D-25 TRENCH PAVEMENT(PERMANENT) REPAIR(E2-19) FOR UTILITY CUTS The unit price bid under the appropriate bid item of the proposal shall cover all cost for providing pavement repair equal to or superior in composition, thickness, etc., to existing pavement as detailed in the Public Works Department typical sections for Pavement and Trench Repair for Utility Cuts, Figures 2000-1 through 2000-3. The results of the street cores that were conducted on the project streets, to determine HMAC depths on existing streets, are provided in these specifications and contract documents. All required paving cuts shall be made with a concrete saw in a true and straight line on both sides of the trench, a minimum of twelve (12)inches outside the trench walls. The trench shall be .. backfilled and the top nine (9) inches shall be filled with required materials as shown on paving details, compacted and level with the finished street surface. This finished grade shall be maintained in a serviceable condition until the paving has been replaced. All residential .. driveways shall be accessible at night and over weekends. It has been determined by the Transportation and Public Works Department that the strip of existing HMAC pavement between the existing gutter and the edge of the trench pavement repair will not hold up if such strip of existing pavement is two (2) feet or less in width. Therefore, at the locations in the project where the trench wall is three (3)feet or less from the lip of the existing gutter, the Contractor shall be required to remove the existing paving to such gutter. The pavement repair shall then be made from a minimum distance of twelve (12) inches outside the trench wall nearest the center of the street to the gutter line. The pavement shall be replaced within a maximum of five (5) working days, providing job placement conditions will permit repaving. If paving conditions are not suitable for repaving, in .. the opinion of the Owner,the repaving shall be done at the earliest possible date. A permit must be obtained from the Department of Engineering Construction Services Section by •� the Contractor in conformance with Ordinance No. 3449 and/or Ordinance No. 792 to make utility cuts in the street.

It is the intent of the City of Fort Worth to comply with the requirements of the Asbestos National Emissions Standards for Hazardous Air Pollutants (NESHAP) found at 40 CFR Part 61, Subpart M. This specification will establish procedures to be used by all Excavators in the removal and disposal of asbestos cement pipe (ACR) in compliance with NESHAP. Nothing in this specification shall be construed to void any provision of a contract or other law, ordinance, regulation or policy whose requirements are more stringent. B. ACP is defined under NESHAP as a Category II, non-friable material in its intact state but which may become friable upon removal, demolition and/or disposal. Consequently, if the removal/ disposal process renders the ACP friable, it is regulated under the disposal requirements of 40 CFR 61.150. A NESHAP notification must be filed with the Texas Department of Health. The notification must be filed at least ten days prior to removal of the material. If it remains in its non - friable state, as defined by the NESHAP, it can be disposed as a conventional construction waste. The Environmental Protection Agency (EPA) defines friable as material, when dry, which may be crumbled, pulverized or reduced to powder by hand pressures. " C. This section defines the generator of hazardous materials. The requirements of Section have been changed for this project (Sanitary Main 244A Village Creek Parallel Collector ON Contract 2). The standard to be used is the Texas Water Development Board Supplemental Contract Conditions CWSRF Tier 3, and DWSFR, page 14, Item 17. Hazardous Materials (See the SRF funding section of the specifications). .. D. It is the intent of the City of Fort Worth that all ACP shall be removed in such careful and prudent manner that it remains intact and does not become friable. The Excavator is responsible to employ those means, methods, techniques and sequences to ensure this result. E. Compliance with all aspects of worker safety and health regulations including but not limited to the OSHA Asbestos Standard is the responsibility of the Excavator. The City of Fort Worth assumes no responsibility for compliance programs, which are the responsibility of the Excavator. (Copy of forms attached) F. The removal and disposal of ACP shall be subsidiary to the cost of installing the new pipe unless otherwise stated or indicated on the project plans or contract documents.

Project Engineer TranSystems Corporation Consultants 500 West 7th Street, Suite 600 Fort Worth,Teras 76102-4773 -. Dear Mr. Lunski: _ Thank you for your initial letter of January 15, 2002, and subsequent submittals concerning - the proposed construction of the City of Fort Worth M-244-A Sanitary Sewer Relief from US 180 to the Village Creek Wastewater Treatment Plant in Fort Worth,Tarrant County,Texas. This project has been assigned Project Number 200200069. Please include this number in all future correspondence concerning this project. Failure to reference the project number may result in a delay. We have reviewed this project in accordance with Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act of 1899. Under Section 404, the U. S. Army Corps of Engineers(US ACE) regulates the discharge of dredged and fill material into waters of the United States, including wetlands. Our responsibility under Section 10 is to regulate any work in, or affecting, navigable waters of the United States. Based on your description of the proposed " work, and other information available to us, we have determined that this project will not involve activities subject to the requirements of Section 10. However, this project will involve activities subject to the requirements of Section 404. Therefore, it will require Department of the Army authorization. It appears that this.project is authorized by nationwide permit 12 for Utility Line Activities. To use this permit, the person responsible for the project must ensure that the work is in compliance with the specifications and conditions listed on the enclosures. Also, if the work occurs on Indian Country/Indian Tribal lands, the person responsible for the project must obtain an individual water quality certification or waiver from the U. S. Environmental Protection Agency, Attention: Marine and Wetlands Section (6WQ-EM), 1445 Ross Avenue, Dallas, Texas 75202, telephone (214)665-6680. Failure to comply with these specifications and conditions invalidates the authorization and may result in a violation of the Clean Water Act. -2— Our verification for the construction of this activity under this nationwide permit is valid until March 18,2007, unless prior to that date the nationwide permit is suspended or revoked,or modified such that the activity would no longer comply with the terms and conditions of the nationwide permit on a regional or national basis. The USACE will issue a public notice announcing the changes when they occur. Furthermore, if you commence,or are under contract to commence, this activity before the date that this nationwide permit is modified or revoked,you will have twelve months from the date of the modification or revocation to complete the activity �- under the present terms and conditions of the nationwide permit. Continued confirmation that an activity complies with the specifications and conditions, and any changes to the nationwide permit, is the responsibility of the permittee. Our review of this project also addressed its effects on endangered species. Based on the information provided,we have determined that this project will not affect any species listed as threatened or endangered by the U.S. Fish and Wildlife Service within our permit area. However, please note that you are responsible for meeting the requirements of general condition 11 on endangered species. - The permitteemust sign and submit to us the enclosed certification that the work, including any required mitigation, was completed in compliance with the nationwide permit. You should submit your certification within 30 days of the completion of work. This permit should not be considered as an approval of the design features of any activity authorized or an implication that such construction is considered adequate for the purpose intended. It does not authorize any damage to private property, invasion of private rights,or any infringement of federal, state, or local laws or regulations.

Lea Chief, Regulatory Branch Enclosures NATIONWIDE PERMIT 12 Utility Line Activities Effective Date: March 18,2002 Activities required for the construction, maintenance and repair of utility lines and associated facilities in waters of the US as follows: (i)Utility lines:The construction,maintenance,or repair of utility lines,including outfall and intake structures and the associated excavation,backfill,or bedding for the utility lines,in all waters of the US,provided there is no change in preconstruction contours. A"utility line"is defined as any pipe or pipeline for the transportation of any gaseous,liquid,liquescent,or slurry substance,for any purpose, and any cable,line,or wire for the transmission for any purpose of electrical energy,telephone,and telegraph messages,and radio and television communication (see Note 1,below).Material resulting from trench excavation may be temporarily sidecast(up to three months) into waters of the US,provided that the material is not placed in such a manner that it is dispersed by currents or other forces.The District Engineer may extend the period of temporary side casting not to exceed a total of 180 days,where appropriate. In wetlands,the top V to 12"of the trench should normally be backfilled with topsoil from the trench.Furthermore,the trench cannot be constructed in such a manner as to drain waters of the US(e.g., backfilling with extensive gravel layers,creating a french drain effect).For example,utility line trenches can be backfilled with clay blocks to ensure that the trench does not drain the waters of the US through which the utility line is installed. Any exposed slopes and stream banks must be stabilized immediately upon completion of the utility line crossing of each waterbody. (ti)Utility line substations:The construction,maintenance,or expansion of a substation facility associated with a power line or utility line in non-tidal waters of the US,excluding non-tidal wetlands adjacent to tidal waters, provided the activity does not result in the loss of greater than 1/2-acre of non-tidal waters of the US. (iii)Foundations for overhead utility line towers,poles,and anchors:The construction or maintenance of foundations for overhead utility line towers,poles,and anchors in all waters of the US,provided the foundations are the minimum size necessary and separate footings for each tower leg(rather than a larger single pad)are used where feasible. (iv)Access roads:The construction of access roads for the construction and maintenance of utility lines, including overhead power lines and utility line substations, in non-tidal waters of the US,excluding non-tidal wetlands adjacent to tidal waters,provided the discharges do not cause the loss of greater than 1/2-acre of non-tidal waters of the US. Access roads shall be the minimum width necessary(see Note 2,below). Access roads must be constructed so that the length of the road minimizes the adverse effects on waters of the US and as near as possible to preconstruction contours and elevations(e.g.,at grade corduroy roads or geotextile/gravel roads).Access roads constructed above preconstruction contours and elevations in waters of the US must be properly bridged or culverted to maintain surface flows. The term"utility line"does not include activities which drain a water of the US,such as drainage tile, or french drains, however,it does apply to pipes conveying drainage from another area_ For the purposes of this NW,the loss of waters of the US includes the filled area plus waters of the US that are adversely affected by flooding, excavation,or drainage as a result of the project.Activities authorized by paragraph(i)through(iv)may not exceed a total of 1/2-acre loss of%caters of the US. Waters of the US temporarily affected by filling,flooding, excavation,or drainage,where the project area is restored to preconstruction contours and elevation,is not included in the calculation of permanent loss of waters of the US.This includes temporary construction mats(e.g., timber, steel,geotextile)used during construction and removed upon completion of the work. Where certain functions and values of waters of the US are permanently adversely affected,such as the conversion of a forested wetland to a herbaceous wetland in the permanently maintained utility line right-of-way, mitigation will be required to reduce the adverse effects of the project to the minimal level. Mechanized land clearing necessary for the construction, maintenance, or repair of utility lines and the construction, maintenance and expansion of utility line substations, foundations for overhead utility lines,and access roads is authorized, provided the cleared area is kept to the minimum necessary and preconstruction ` contours are maintained as near as possible. The area of waters of the US that is filled,excavated, or flooded mast be limited to the minimum necessary to construct the utility line, substations, foundations,and access roads.Excess material must be removed to upland areas immediately upon completion of construction. This NWP may authorize — utility lines in or affecting navigable waters of the US even if there is no associated discharge of dredged or fill material(See 33 CFR part 322). Notification:The permittee must notify the District Engineer in accordance with General Condition 13,if any of the following criteria are met: (a)Mechanized land clearing in a forested wetland for the utility line right-of-way; (b)A Section 10 permit is required; (c)The utility line in waters of the US,excluding overhead lines,exceeds 500 feet; (d)The utility line is placed within a jurisdictional area(Le.,water of the US),and it runs parallel to a stream bed that is within that jurisdictional area; (e)Discharges associated with the construction of utility line substations that result in the loss of greater than 1/10- acre of waters of the US; (f)Permanent access roads constructed above grade in waters of the US for a distance of more than 500 feet;or (g)Permanent access roads constructed in waters of the US with impervious materials.(Sections 10 and 404) Note 1.Overhead utility lines constructed over Section 10 waters and utility lines that are routed in or under Section 10 waters without a discharge of dredged or fill material require a Section 10 permit;except for pipes or pipelines used to transport gaseous,liquid,liquescent,or slung substances over navigable waters of the US,which are considered to be bridges,not utility lines,and may require a permit from the USCG pursuant to section 9 of the Rivers and Harbors Act of 1899.However,any discharges of dredged or fill material associated with such pipelines will require a Corps permit under Section 404. Note 2:Access roads used for both construction and maintenance may be authorized,provided they meet the terms and conditions of this NWP.Access roads used solely for construction of the utility line must be removed upon completion of the work and the area restored to preconstruction contours,elevations,and wetland conditions. Temporary access roads for construction may be authorized by NWP 33. Note 3:Where the proposed utility line is constructed or installed in navigable waters of the US(i.e.,Section 10 waters),copies of the PCN and NWP verification will be sent by the Corps to the National Oceanic and Atmospheric Administration(NOAA),National Ocean Service(NOS),for charting the utility line to protect navigation. NATIONWIDE PERMIT GENERAL CONDITIONS The following General Conditions must be followed in order for any authorization by an NWP to be valid: 1.Navigation.No activity may cause more than a minimal adverse effect on navigation 2.Proper Maintenance.Any structure or fill authorized shall be properly maintained,including maintenance to ensure public safety. 3.Soil Erosion and Sediment Controls.Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction,and all exposed soil and other fills,as well as any work below the ordinary high water mark or high tide line,must be permanently stabilized at the earliest practicable date.Permittees are encouraged to perform work within waters of the United States during periods of low-flow or no-flow. 4.Aquatic Life Movements.No activity may substantially disrupt the necessary life-cycle movements of those species of aquatic life indigenous to the waterbody,including those species that normally migrate through the area, �. unless the activity's primary purpose is to impound water.Culverts placed in streams must be installed to maintain low flow conditions. 5.Equipment. Heavy equipment working in wetlands must be placed on mats,or other measures must be taken to minimize soil disturbance. 6.Regional and Case-By-Case Conditions.The activity must comply with any regional conditions that may have .. 2 been added by the Division Engineer(see 33 CFR 330.4(e))and with any case specific conditions added by the Corps or by the state or tribe in its Section 401 Water Quality Certification and Coastal Zone Management Act consistency determination. Note: Statewide Regional Conditions have been added for activities within Texas. 7.Wild and Scenic Rivers.No activity may occur in a component of the National Wild and Scenic River System;or in a river officially designated by Congress as a"study river"for possible inclusion in the system,while the river is in an official study status;unless the appropriate Federal agency,with direct management responsibility for such river,has determined in writing that the proposed activity will not adversely affect the Wild and Scenic River designation,or study status.Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency in the area(e.g.,National Park Service,U.S.Forest Service,Bureau of Land Management, U.S.Fish and Wildlife Service). 8.Tribal Rights.No activity or its operation may impair reserved tribal rights,including,but not limited to, reserved water rights and treaty fishing and hunting rights. 9.Water Quality.(a)in certain states and tribal lands an individual 401 Water Quality Certification must be obtained or waived(See 33 CFR 330.4(c)). (b)For NWPs 12, 14, 17, 18,32,39,40,42,43,and 44,where the state or tribal 401 certification(either generically or individually)does not require or approve water quality management measures,the permittee must provide water quality management measures that will ensure that the authorized work does not result in more than minimal degradation of water quality(or the Corps determines that compliance with state or local standards,where applicable,will ensure no more than minimal adverse effect on water quality).An important component of water - quality management includes stormwater management that minimizes degradation of the downstream aquatic system, including water quality(refer to General Condition 21 for stormwater management requirements).Another important component of water quality management is the establishment and maintenance of vegetated buffers next to open waters,including streams(refer to General Condition 19 for vegetated buffer requirements for the NWPs). This condition is only applicable to projects that have the potential to affect water quality.While appropriate measures must be taken,in most cases it is not necessary to conduct detailed studies to identify such measures or to require monitoring. 10.Coastal Zone Management.In certain states,an individual state coastal zone management consistency concurrence must be obtained or waived(see 33 CFR 330.4(d)). 11.Endangered Species.(a)No activity is authorized under any NWP which is likely to jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation,as identified under the Federal Endangered Species Act(ESA),or which will destroy or adversely modify the critical habitat of such species.Non-federal permittees shall notify the District Engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project,or is located in the designated critical habitat and shall not begin work on the activity until notified by the District Engineer that the requirements of the ESA have been satisfied and that the activity is authorized.For activities that may affect Federally-listed endangered or threatened species or designated critical habitat,the notification must include the name(s)of the endangered or threatened species that may be affected by the proposed work or that utilize the designated critical habitat that may be affected by the proposed work.As a result of formal or informal consultation with the FWS or NMFS the District Engineer may add species- specific regional endangered species conditions to the NWPs. (b)Authorization of an activity by a NWP does not authorize the"take"of a threatened or endangered species as defined under the FSA.In the absence of separate authorization(e.g.,an FSA Section 10 Permit,a Biological Opinion with"incidental take"provisions,etc.)from the USFWS or the NMFS,both lethal and non-lethal"takes"of protected species are in violation of the ESA.Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the.offices of the USFWS and NMFS or their world wide web pages at httpJ/www.fws.gov/r9endspplendspp.htn-d and http://www.nmfs.noaa.gov/prot_restoverview/es.htn-d respectively. QQ 3U. gQ : '1i�U19 Sb%, 12.Historic Properties.No activity which may affect historic properties listed,or eligible for listing, in the National Register of Historic Places is authorized,until the District Engineer has complied with the provisions of 33 CFR part 325,Appendix C.The prospective permittee must notify the District Engineer if the authorized activity may affect any historic properties listed,determined to be eligible,or which the prospective permittee has reason to believe may be eligible for listing on the National Register of Historic Places,and shall not begin the activity until notified by the District Engineer that the requirements of the National Historic Preservation Act have been satisfied and that the activity is authorized.Information on the location and existence of historic resources can be obtained from the State Historic Preservation Office and the National Register of Historic Places(see 33 CFR 330.4(g)).For activities that may affect historic properties listed in,or eligible for listing in,the National Register of Historic Places,the notification must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. 13.Notification. (a)Timing;where required by the terms of the NWP,the prospective permittee must notify the District Engineer with a preconstruction notification(PCN)as early as possible.The District Engineer must determine if the notification is complete within 30 days of the date of receipt and can request additional information necessary to make the PCN complete only once.However,if the prospective permittee does not provide all of the requested information,then the District Engineer will notify the prospective permittee that the notification is still incomplete and the PCN review process will not commence until all of the requested information has been received by the District Engineer.The prospective permittee shall not begin the activity: (1)Until notified in writing by the District Engineer that the activity may proceed under the NWP with any special conditions imposed by the District or Division Engineer;or (2)If notified in writing by the District or Division Engineer that an Individual Permit is required;or (3)Unless 45 days have passed from the District Engineces receipt of the complete notification and the prospective permittee has not received written notice from the District or Division Engineer.Subsequently,the permittee's right to proceed under the NWP may be modified,suspended,or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2).

In addition,the PCN must include all of the following: (i)Sufficient baseline information identifying the approved channel depths and configurations and existing facilities.Minor deviations are authorized,provided the approved flood control protection or drainage is not increased; (ii)A delineation of any affected special aquatic sites,including wetlands;and, _ (iii)Location of the dredged material disposal site; (11)For NWP 33(Temporary Construction,Access,and Dewatering),the PCN must also include a restoration plan of reasonable measures to avoid and minimize adverse effects to aquatic resources; (12)For NWPs 39,43 and 44,the PCN must also include a written statement to the District Engineer explaining how avoidance and minimization for losses of waters of the US were achieved on the project site; (13)For NWP 39 and NWP 42,the PCN must include a compensatory mitigation proposal to offset losses of waters of the US or justification explaining why compensatory mitigation should not be required.For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; -- (14)For NWP 40(Agricultural Activities),the PCN must include a compensatory mitigation proposal to offset losses of waters of the US.This NWP does not authorize the relocation of greater than 300 linear-feet of existing serviceable drainage ditches constructed in non-tidal streams unless,for drainage ditches constructed in intermittent non-tidal streams,the District Engineer waives this criterion in writing,and the District Engineer has determined that the project complies with all terms and conditions of this NWP,and that any adverse impacts of the project on the aquatic environment are minimal,both individually and cumulatively; (15)For NWP 43(Stormwater Management Facilities),the PCN must include, for the construction of new stormwater management facilities,a maintenance plan(in accordance with state and local requirements,if applicable)and a compensatory mitigation proposal to offset losses of waters of the US.For discharges that cause the loss of greater than 300 linear feet of an intermittent stream bed,to be authorized,the District Engineer must as determine that the activity complies with the other terms and conditions of the NWP,determine adverse environmental effects are minimal both individually and cumulatively,and waive the limitation on stream impacts in writing before the permittee may proceed; (16)For NWP 44(Mining Activities),the PCN must include a description of all waters of the US adversely affected by the project,a description of measures taken to minimize adverse effects to waters of the US,a description of measures taken to comply with the criteria of the NWP,and a reclamation plan(for all aggregate mining activities in isolated waters and non-tidal wetlands adjacent to headwaters and any hard rock/mineral mining activities); (17)For activities that may adversely affect Federally-listed endangered or threatened species,the PCN must include the name(s)of those endangered or threatened species that may be affected by the proposed work or utilize the designated critical habitat that may be affected by the proposed work;and (18)For activities that may affect historic properties listed in,or eligible for listing in,the National Register of Historic Places,the PCN must state which historic property may be affected by the proposed'work or include a vicinity map indicating the location of the historic property. (c)Form of Notification:The standard Individual Permit application form(Form ENG 4345)may be used as the 5 a notification but must clearly indicate that it is a PCN and must include all of the information required in(b)(1)-(18) of General Condition 13.A letter containing the requisite information may also be used. (d)District Engineer's Decision: In reviewing the PCN for the proposed activity,the District Engineer will determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or may be contrary to the public interest.The prospective permittee may submit a proposed mitigation plan with the PCN to expedite the process.The District Engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are minimal.If the District Engineer determines that the activity complies with the terns and conditions of the NWP and that the adverse effects on the aquatic environment are minimal,after considering mitigation,the District Engineer will notify the permittee and include any conditions the District Engineer deems necessary.The District Engineer must approve any compensatory mitigation proposal before the permittee commences work.If the prospective permittee is required to submit a compensatory mitigation proposal with the PCN,the proposal may be either conceptual or detailed.If the prospective permittee elects to submit a compensatory mitigation plan with the PCN,the District Engineer will expeditiously review the proposed compensatory mitigation plan.The District Engineer must review the plan within " 45 days of receiving a complete PCN and determine whether the conceptual or specific proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment.If the net adverse effects of the project on the aquatic environment(after consideration of the compensatory mitigation proposal)are determined by the District ,m Engineer to be minimal,the District Engineer will provide a timely written response to the applicant The response will state that the project can proceed under the terms and conditions of the NWP. If the District Engineer determines that the adverse effects of the proposed work are more than minimal,then the District Engineer will notify the applicant either:(1)That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an Individual Permit;(2)that the project is authorized under the NWP subject to the applicants submission of a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level;or(3)that the project is authorized under the NWP with specific modifications or conditions.Where the District Engineer determines that mitigation is required to ensure no more than minimal adverse effects occur to the aquatic environment,the activity will be authorized within the 45-day PCN period.The authorization will include the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level.When conceptual mitigation is included,or a mitigation plan is required under item(2)above,no work in waters of the US will occur until the District Engineer has approved a specific mitigation plan. (e)Agency Coordination:The District Engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the terms and conditions of the NWPs and the need for mitigation to reduce the projects adverse environmental effects to a minimal level. a* For activities requiring notification to the District Engineer that result in the loss of greater than 1/2-acre of waters of the US,the District Engineer will provide immediately(e.g.,via facsimile transmission,overnight mail,or other expeditious manner)a copy to the appropriate Federal or state offices(USFWS,state natural resource or water quality agency,EPA,State Historic Preservation Officer(SHPO),and,if appropriate,the NMFS).With the exception of NWP 37,these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the District Engineer notice that they intend to provide substantive,site-specific comments.If so contacted by an agency,the District Engineer will wait an additional 15 calendar days before making a decision on the notification.The District Engineer will fully consider agency comments received within the specified time frame, but will provide no response to the resource agency,except as provided below.The District Engineer will indicate in the administrative record associated with each notification that the resource agencies'concerns were considered.As -- required by section 305(b)(4)(B)of the Magnuson-Stevens Fishery Conservation and Management Act,the District Engineer will provide a response to NMFS within 30 days of receipt of any Essential Fish Habitat conservation recommendations.Applicants are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. (f)Wetland Delineations: Wetland delineations must be prepared in accordance with the current method required by the Corps(For NWP 29 see paragraph(b)(9)(iii)for parcels less than(114-acre in size).The permittee may ask the Corps to delineate the special aquatic site.There may be some delay if the Corps does the delineation. 6 Furthermore,the 45-day period will not start until the wetland delineation has been completed and submitted to the Corps,where appropriate. 14,Compliance Certification.Every permittee who has received NWP verification from the Corps will submit a signed certification regarding the completed work and any required mitigation.The certification will be forwarded by the Corps with the authorization letter and will include: (a)A statement that the authorized work was done in accordance with the Corps authorization,including any general or specific conditions; (b)A statement that any required mitigation was completed in accordance with the permit conditions;and (c)The signature of the permittee certifying the completion of the work and mitigation. 15.Use of Multiple Natiomvide Permits.The use of more than one NWP for a single and complete project is prohibited,except when the acreage loss of waters of the US authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit(e.g.if a road crossing over tidal waters is constructed under NWP 14,with associated bank stabilization authorized by NWP 13,the maximum acreage loss of waters of the US for the total project cannot exceed 1/3-acre). 16.Water Supply Intakes.No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may occur in the proximity of a public water supply intake except where the activity is for repair of the public water supply intake structures or adjacent bank stabilization. 17.Shellfish Beds.No activity,including structures and work in navigable waters of the US or discharges of - dredged or fill material,may occur in areas of concentrated shellfish populations,unless the activity is directly related to a shellfish harvesting activity authorized by NWP 4. 18.Suitable Material.No activity,including structures and work in navigable waters of the US or discharges of dredged or fill material,may consist of unsuitable material(e.g.,trash,debris,car bodies,asphalt,etc.)and material used for construction or discharged must be free from toxic pollutants in toxic amounts(see section 307 of the CWA). 19.Mitigation.The District Engineer will consider the factors discussed below when determining the acceptability of appropriate and practicable mitigation necessary to offset adverse effects on the aquatic environment that are more than minimal. (a)The project must be designed and constructed to avoid and minimize adverse effects to waters of the US to the maximum extent practicable at the project site(i.e.,on site). (b)Mitigation in all its forms(avoiding,minimizing,rectifying,reducing or compensating)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. (c)Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland impacts requiring a PCN,unless the District Engineer determines in writing that some other form of mitigation would be more environmentally appropriate and provides a project-specific waiver of this requirement.Consistent with National policy,the District Engineer will establish a preference for restoration of wetlands as compensatory mitigation,with preservation used only in exceptional circumstances. (d)Compensatory mitigation(i.e.,replacement or substitution of aquatic resources for those impacted)will not h� used to increase the acreage losses allowed by the acreage limits of some of the NWPs.For example, 1/4-acre of wetlands cannot be created to change a 3/4-acre loss of wetlands to a 1/2-acre loss associated with NWP 39 verification.However, 1/2-acre of created wetlands can be used to reduce the impacts of a 112-acre loss of wetlands to the minimum impact level in order to meet the minimal impact requirement associated with NWPs. (e)To be practicable,the mitigation must be available and capable of being done considering costs,existing technology,and logistics in light of the overall project purposes.Examples of mitigation that may be appropriate and practicable include,but are not limited to: reducing the size of the project;establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams;and replacing losses of aquatic resource functions and values by creating,restoring,enhancing,or preserving similar functions and values,preferably in the same 7 watershed �^ (f)Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the establishment,maintenance,and legal protection(e.g.,easements,deed restrictions)of vegetated buffers to open waters.In many cases,vegetated buffers will be the only compensatory mitigation required. Vegetated buffers should consist of native species.The width of the vegetated buffers required will address documented water quality or aquatic habitat loss concerns.Normally,the vegetated buffer will be 25 to 50 feet wide on each side of the stream,but the District Engineers may require slightly wider vegetated buffers to address documented water quality or habitat loss concerns.Where both wetlands and open waters exist on the project site, the Corps will determine the appropriate compensatory mitigation(e.g.,stream buffers or wetlands compensation) based on what is best for the aquatic environment on a watershed basis.In cases where vegetated buffers are determined to be the most appropriate form of compensatory mitigation,the District Engineer may waive or reduce -� the requirement to provide wetland compensatory mitigation for wetland impacts. (g)Compensatory mitigation proposals submitted with the"notification"may be either conceptual or detailed. If conceptual plans are approved under the verification,then the Corps will condition the verification to require detailed plans be submitte&and approved by the Corps prior to construction of the authorized activity in waters of the US. (h)Permittees may propose the use of mitigation banks,in-lieu fee arrangements or separate activity-specific compensatory mitigation.In all cases that require compensatory mitigation,the mitigation provisions will specify the party responsible for accomplishing and/or complying with the mitigation plan 20.Spawning Areas.Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material,in spawning areas during spawning seasons must be avoided to the maximum extent practicable.Activities that result in the physical destruction(e.g.,excavate,fill,or smother downstream by substantial turbidity)of an important spawning area are not authorized- 2 1. uthorized.21.Management of Water Flows.To the maximum extent practicable,the activity must be designed to maintain preconstruction downstream flow conditions(e.g.,location,capacity,and flow rates).Furthermore,the activity must not permanently restrict or impede the passage of normal or expected high flows(unless the primary purpose of the " fill is to impound waters)and the structure or discharge of dredged or fill material must withstand expected high flows.The activity must,to the maximum extent practicable,provide for retaining excess flows from the site,provide for maintaining surface flow rates from the site similar to preconstruction conditions,and provide for not increasing water flows from the project site,relocating water,or redirecting water flow beyond preconstruction conditions. Stream channelizing will be reduced to the minimal amount necessary,and the activity must, to the maximum extent practicable,reduce adverse effects such as flooding or erosion downstream and upstream of the project site,unless the activity is part of a larger system designed to manage water flows.In most cases, it will not be a requirement to conduct detailed studies and monitoring of water flow. This condition is only applicable to projects that have the potential to affect waterflows.While appropriate measures must be taken,it is not necessary to conduct detailed studies to identify such measures or require monitoring to ensure their effectiveness.Nomnally,the Corps will defer to state and local authorities regarding management of water flow. 22.Adverse Effects From Impoundments.If the activity creates an impoundment of water, adverse effects to the aquatic system due to the acceleration of the passage of water,and/or the restricting its flow shall be minimized to the maximum extent practicable.This includes structures and work in navigable waters of the US,or discharges of dredged or fill material. 23.Waterfowl Breeding Areas.Activities,including structures and work in navigable waters of the US or discharges of dredged or fill material, into breeding areas for migratory waterfowl must be avoided to the maximum extent practicable. 24.Removal of Temporary Fills.Any temporary fills must be removed in their entirety and the affected areas returned to their preexisting elevation. 8 25.Designated Critical Resource Waters.Critical resource waters include,NOAA-designated marine sanctuaries, National Estuarine Research Reserves,National Wild and Scenic Riven,critical habitat for Federally listed threatened and endangered species,coral reefs,state natural heritage sites,and outstanding national resource waters or other waters officially designated by a state as having particular environmental or ecological significance and identified by the District Engineer after notice and opportunity for public comment.The District Engineer may also designate additional critical resource waters after notice and opportunity for comment. (a)Except as noted below,discharges of dredged or fill material into waters of the US are not authorized by NWPs 7, 12, 14, 16, 17,21,29,31,35,39,40,42,43,and 44 for any activity within,or directly affecting,critical resource waters,including wetlands adjacent to such waters.Discharges of dredged or fill materials into waters of the US may be authorized by the above NWPs in National Wild and Scenic Rivers if the activity complies with General Condition 7.Further,such discharges may be authorized in designated critical habitat for Federally listed threatened or endangered species if the activity complies with General Condition 11 and the USFWS or the NMFS has concurred in a determination of compliance with this condition. m (b)For NWPs 3,8, 10, 13, 15, 18, 19,22,23,25,27,28,30,33,34,36,37,and 38,notification is required in accordance with General Condition 13,for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters.The District Engineer may authorize activities under these NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal 26.Fills Within 100-Year Floodplain.For purposes of this General Condition, 100-year floodplain will be identified through the existing Federal Emergency Management Agency's(FEMA)Flood Insurance Rate Maps or FEMA-approved local floodplain maps. (a)Discharges in Floodplain;Below Headwaters.Discharges of dredged or fill material into waters of the US within the mapped 100-year floodplain,below headwaters(i.e. five cfs),resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,43,and 44. (b)Discharges in Floodway;Above Headwaters.Discharges of dredged or fill material into waters of the US within the FEMA or locally mapped floodway,resulting in permanent above-grade fills,are not authorized by NWPs 39,40,42,and 44. (c)The permittee must comply with any applicable FEMA-approved state or local floodplain management requirements. 27.Construction Period.For activities that have not been verified by the Corps and the project was commenced or under contract to commence by the expiration date of the NWP(or modification or revocation date),the work must be completed within 12-months after such date(including any modification that affects the project). For activities that have been verified and the project was commenced or under contract to continence within the verification period,the work must be completed by the date determined by the Corps. For projects that have been verified by the Corps,an extension of a Corps approved completion date maybe requested.This request must be submitted at least one month before the previously approved completion date. FURTHER INFORb1ATION 1.District Engineers have authority to determine if an activity complies with the terms and conditions of an NWP. 2.NWPs do not ob: to the need to obtain other Federal,state,or local permits,approvals,or authorizations required by law. 3.NWPs do not grant any property rights or exclusive privileges. 4.NWPs do not authorize any injury to the property or rights of others. 5.NWPs do not authorize interference with any existing or proposed Federal project. DFFINITIONS Best Management Practices(BMPs): BMPs are policies,practices,procedures,or structures implemented to mitigate the adverse environmental effects on surface water quality resulting from development.B AN are 9 FFICc,I I ECS 1� �, W'Ogmt YEN, categorized as structural or non-structural.A BMP policy may affect the limits on a development. -- Compensatory Mitigation:For purposes of Section 10/404,compensatory mitigation is the restoration,creation, enhancement,or in exceptional circumstances,preservation of wetlands and/or other aquatic resources for the purpose of compensating for unavoidable adverse impacts which remain after all appropriate and practicable , avoidance and tninimization has been achieved Creation:The establishment of a wetland or other aquatic resource where one did not formerly exist. Enhancement:Activities conducted in existing wetlands or other aquatic resources that increase one or more aquatic functions. Ephemeral Stream An ephemeral stream has flowing water only during and for a short duration after, precipitation events in a typical year.Ephemeral stream beds are located above the water table year-round. Groundwater is not a source of water for the stream.Runoff from rainfall is the primary source of water for stream flow. Farm Tract:A unit of contiguous land under one ownership that is operated as a farm or part of a farm Flood Fringe:That portion of the 100-year floodplain outside of the floodway(often referred to as"floodway „* fringe"). Floodway:The area regulated by Federal,state,or local requirements to provide for the discharge of the base flood so the cumulative increase in water surface elevation is no more than a designated amount(not to exceed one foot as set by the National Flood Insurance Program)within the 100-year floodplain. Independent Utility:A test to determine what constitutes a single and complete project in the Corps regulatory program A project is considered to have independent utility if it would be constructed absent the construction of other projects in the project area.Portions of a multi-phase project that depend upon other phases of the project do not have independent utility.Phases of a project that would be constructed even if the other phases were not built can be considered as separate single and complcte projects with independent utility. Intermittent Stream:An intermittent stream has flowing water during certain times of the year,when groundwater provides water for stream flow.During dry periods,intermittent streams may not have flowing water. Runoff from rainfall is a supplemental source of water for stream flow. Loss of Waters of the US:Waters of the US that include the filled area and other waters that are permanently adversely affected by flooding,excavation,or drainage because of the regulated activity.Permanent adverse effects include permanent above-grade,at-grade,or below-grade fills that change an aquatic area to dry land,increase the bottom elevation of a waterbody,or change the use of a waterbody.The acreage of loss of waters of the US is the threshold measurement of the impact to existing waters for determining whether a project may qualify for an NWP;it is not a net threshold that is calculated after considering compensatory mitigation that may be used to offset losses of aquatic functions and values.The loss of stream bed includes the linear feet of stream bed that is filled or excavated. Impacts to ephemeral streams are not included in the linear foot measurement of loss of stream bed for the purpose of determining compliance with the linear foot limits of NWPs 39,40,42,and 43.Waters of the US temporarily filled,flooded,excavated,or drained,but restored to precoastruction contours and elevations after construction,are not included in the measurement of loss of waters of the US. Non-tidal Wetland:A non-tidal wetland is a wetland(i.e.,a water of the US)that is not subject to the ebb and flow of tidal waters.The definition of a wetland can be found at 33 CFR 328.3(b).Non-tidal wetlands contiguous to tidal waters are located landward of the high tide line(i.e.,spring high tide line). Open Water:An area that,during a year with normal patterns of precipitation,has standing or flowing water for sufficient duration to establish an ordinary high water mark.Aquatic vegetation within the area of standing or flowing water is either non-emergent,sparse,or absent.Vegetated shallows are considered to be open waters.The term"open water"includes rivers,streams,lakes,and ponds.For the purposes of the NWPs,this term does not include ephemeral waters. Perennial Stream:A perennial stream has flowing water year-round during a typical year.The water table is located above the stream bed for most of the year.Groundwater is the primary source of water for stream flow. Runoff from rainfall is a supplemental source of water for stream flow. Permanent Above-grade Fill:A discharge of dredged or fill material into waters of the US,including wetlands, that results in a substantial increase in ground elevation and permanently converts part or all of the waterbody to dry land.Structural fills authorized by NWPs 3,25,36,etc.are not included. Preservation: The protection of ecologically important wetlands or other aquatic resources in perpetuity through 10 the implementation of appropriate legal and physical mechanisms.Preservation may include protection of upland areas adjacent to wetlands as necessary to ensure protection and/or enhancement of the overall aquatic ecosystem Restoration:Re-establishment of wetland and/or other aquatic resource characteristics and function(s)at a site where they have ceased to exist,or exist in a substantially degraded state. Riffle and Pool Complex: Riffle and pool complexes are special aquatic sites under the 404(b)(1)Guidelines. Riffle and pool complexes sometimes characterize steep gradient sections of streams. Such stream sections are recognizable by their hydraulic characteristics.The rapid movement of water over a course substrate in riffles results in a rough flow,a turbulent surface,and high dissolved oxygen levels in the water.Pools are deeper areas associated with riffles.A slower stream velocity,a streaming flow,a smooth surface,and a finer substrate characterize pools. Single and Complete Project:The term"single and complete project"is defined at 33 CFR 330.2(1)as the total project proposed or accomplished by one owner/developer or partnership or other association of owners/developers (see definition of independent utility).For linear projects,the"single and complete project"(i.e.,a single and complete crossing)will apply to each crossing of a separate water of the US(i.e.,a single waterbody)at that location.An exception is for linear projects crossing a single waterbody several times at separate and distant locations:each crossing is considered a single and complete project.However,individual channels in a braided stream or river,or individual amu of a large,irregularly shaped wetland or lake,etc.,are not separate waterbodies. Stormwater Management:Stormwater management is the mechanism for controlling stormwater runoff for the purposes of reducing downstream erosion,water quality degradation,and flooding and mitigating the adverse effects of changes in land use on the aquatic environment. Stormwater Management Facilities:Stormwater management facilities are those facilities,including but not limited to,stormwater retention and detention ponds and BMPs,which retain water for a period of time to control runoff and/or improve the quality(i.e.,by reducing the concentration of nutrients,sediments,hazardous substances and other pollutants)of Stormwater runoff. Stream Bed:The substrate of the stream channel between the ordinary high water marks.The substrate may be bedrock or inorganic particles that range in size from clay to boulders.Wetlands contiguous to the stream bed,but outside of the ordinary high water marks,are not considered part of the stream bed. Stream Channelization:The manipulation of a stream channel to increase the rate of water flow through the stream channel.Manipulation may include deepening,widening,straightening,armoring,or other activities that change the stream cross-section or other aspects of stream channel geometry to increase the rate of water flow through the stream channel.A channelized stream remains a water of the US,despite the modifications to increase the rate of water flow. Tidal Wetland:A tidal wetland is a wetland(i.e.,water of the US)that is inundated by tidal waters.The definitions of a wetland and tidal waters can be found at 33 CFR 328.3(b)and 33 CFR 328.3(f),respectively.Tidal waters rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and sun.Tidal waters end where the rise and fall of the water surface can no longer be practically measured in a predictable rhythm due to masking by other waters,wind,or other effects.Tidal wetlands are located channelward of the high tide line(i.e.,spring high tide line)and are inundated by tidal waters two times per lunar month,during spring high tides. Vegetated Buffer:A vegetated upland or wetland area next to rivers,streams,lakes,or other open waters which separates the open water from developed areas,including agricultural land.Vegetated buffers provide a variety of aquatic habitat functions and values(e.g..aquatic habitat for fish and other aquatic organisms,moderation of water temperature changes,and detritus for aquatic food webs)and help improve or maintain local water quality.A vegetated buffer can be established by maintaining an existing vegetated area or planting native trees,shrubs,and herbaceous plants on land next to open-waters.Mowed lawns are not considered vegetated buffers because they provide little or no aquatic habitat functions and values.The establishment and maintenance of vegetated buffers is a method of compensatory mitigation that can be used in conjunction with the restoration,creation,enhancement,or preservation of aquatic habitats to ensure that activities authorized by NWPs result in minimal adverse effects to the aquatic environment.(See General Condition 19.) . Vegetated Shallows:Vegetated shallows are special aquatic sites under the 404(b)(1)Guidelines.They are areas that are permanently inundated and under normal circumstances have rooted aquatic vegetation,such as seagrasses in marine and estuarine systems and a variety of vascular rooted plants in freshwater systems. Waterbody:A waterbody is any area that in a normal year has water flowing or standing above ground to the "� 11 extent that evidence of an ordinary high water mark is established.Wetlands contiguous to the waterbody are » considered part of the waterbody.

TNRCC appreciates the opportunity to clarify the conditions of the certification of the NWPs. Please consider this letter as the final certification decision for the Notice of Issuance of Nationwide Permits published in the Federal Register(Part II, Vol. 67,No. 10, y. pages 2020-2095)on January 15,2002,with corrections published in the Federal Register(Vol.67,No.30, pages 6692-6695)on February 13,2002. As stated in the March 18,2002 letter the TYRCC certifies that the activities authorized by NWPs 1,2,4, 5,6,9, 10, 11,20,23,24,28,34,and 35 should not result in a violation of established Texas Water Quality Standards as required by Section 401 of the Federal Clean Water Act and pursuant to Title 30, Texas Administrative Code(TAC),Chapter 279. The TNRCC conditionally certifies that the activities authorized by NWPs 3,7, 12, 13, 14, 15, 16, 17, 18, 19,21,22,25,27,29,30,31,32,33,36,37,38,39,40,41,42,43,and 44 should not result in a violation of established Texas Water Quality Standards as required by Section 401 of the Federal Clean Water Act and pursuant to Title 30,TAC,Chapter 279,provided that the conditions in Enclosure 1 are followed. This certification decision is limited to those activities under the jurisdiction of the TNRCC. For activities related to the production and exploration of oil and gas,Texas Railroad Commission certification is required as provided in the Texas Water Code §26.131. Per your request, the TNRCC's has reformatted the conditions of the March 18, 2002, conditional certification letter to make it clear that these are conditions of the TNRCC's water quali cation and added a statement that for those NWPs that are conditionally certified to require �qf a.Best Management Practice(BMP),the applicant must choose at least one of the listed BMP ` Lit--�V ed'. �5�r� P.O.Box 13087 • Austin,Texas 78711-3087 • 512P239-1000 • Internet address: e.o-us or.-:c!w:te;�.!r_7�;e-c>iy,my-based in: Brigadier General David P.Melcher U.S. Army Corps of Engineers Nationwide Permits Certification Page 2 April 4,2002 the statement that if the applicant does not choose a BUT from the list,individual certification from TNRCC will be required. Subsurface drains for erosion control and gravel bag berms for sediment control have been deleted from the list of BMPs.These changes are shown in Enclosure 1. These water quality certification conditions are intended to enhance the water quality protection goals of the Corps NWP General Condition#3,Soil Erosion and Sediment Control and General Condition#9 Water Quality. The TNRCC conditions address three broad categories of water quality management with specific BMPs recommended for each category. Enclosure 2 is provided as a quick reference of TNRCC conditions for all MVPs. A detailed description of the BMPs*is also being provided as Enclosure 3. - The TNRCC is conditioning the water quality certification on our being copied on any written notification to an applicant of a mitigation waiver. Also, while a limited number of waivers for intermittent streams greater than 300 feet are anticipated, NWP 39,40,and 42 are conditionally certified to require the Corps to copy TNRCC on all written approvals of waivers for impacts to these streams. The TNRCC is requesting this information to fulfill its responsibility to ensure water of the state is appropriately protected by . undcrstanding the impact of waivers being granted in Texas. In response to TNRCC's request for including additional information in the annual mitigation report, you m directed TNRCC to the Regulatory Branch at Corps Headquarters. TNRCC staff will continue to work with Corps headquarters to encourage others waters,such as free flowing streams which the Corps has identified as vital aquatic ecosystems,be incorporated into the annual mitigation report on NWPs. As active partners in the regulatory process ofNWPs,the TNRCC would still request that a copy of the NWP mitigation report be sent to the TNRCC. The Corps has indicated they consider the TNRCC's conditional certification of NWP 16 as denied without prejudice because the Corps Considers the standard not reasonably enforceable.The TNRCC routinely issues permits with Total Suspended Solids (TSS) limits and notes that TSS limits are commonly accepted technological requirements for a number of industries identified in 40 CFR§405-472(Effluent Guidelines and Standards). Furthermore,the condition is part of the approved Tier 1 Checklist under the MOA between TNRCC and the Corps. Therefore,we reiterate that NWP 16 is conditionally c:rtified with the requirement that return water from upland contained disposal areas not exceed a TSS concentration of 300 mg/l unless an individual certification has been issued with site-specific TSS limits. Applicants for NWP 16 may request a site-specific TSS limit from the TNRCC for effluent permitted under NWP 16. Applicants should be aware that site-specific TSS limits may be increased or decreased,depending on the characteristics of the receiving water. TNRCC also reserves the right to retain the 300 mg/l limit if no additional information warranting a site-specific modification is presented by the applicant. The TNRCC has reviewed the Notice of Issuance of Nationwide Permits for consistency with the goals and policies of the Texas Coastal Management Program(CMP)in accordance with the regulations of the Coastal Coordination Council,31 TAC§50530,Amendment 1,and determined that the action is consistent with the applicable CMP goals and policies. Brigadier General David P.Melcher U.S. Army Corps of Engineers Nationwide Permits Certification Page 3 April 4,2002 This certification decision was reviewed for consistency with the CMP's development in critical areas policy (31 TAC §501.14(h)) and dredging and dredged material disposal and placement policy (31 TAC §501.146)).This certification decision complies with the CMP goals(31 TAC§501.12(1,2,3,5))applicable to these policies. Wetlands play a major role in maintaining-water quality and are protected by the Texas Surface Water Quality Standards. We support a goal of no net loss of wetlands. To this end, we support wetland impactstlosses being avoided,minimized,or mitigated in accordance with Section 404 Guidelines. The TNRCC reserves the right to modify this certification if additional information identifies specific areas where significant impacts,including cumulative or secondary impacts,are occurring,and the use of these NWPs would be inappropriate. No review of property rights, location of property lines, nor the distinction between public and private ownership has been made, and this certification may not be used in any way with regard to questions of ownership.

Vegetation effectively reduces erosion in swales,stockpiles, berms, mild to medium slopes, and along roadways. Other techniques such as matting, mulches, and grading may be required to assist in the establishment of vegetation. Materials: • The type of temporary vegetation used on a site is a function of the season and the availability of water for irrigation. • Temporary vegetation should be selected appropriately for the area. • County agricultural extension agents are a good source for suggestions for temporary vegetation. • All seed should be high quality,U.S.Dept.of Agriculture certified seed. Installation: • Grading must be completed prior to seeding. • Slopes should be minimized. • Erosion control structures should be installed. • Seedbeds should be well pulverized,loose,and uniform. • Fertilizers should be applied at appropriate rates. • Seeding rates should be applied as recommended by the county agricultural extension agent. • The seed should be applied uniformly. • Steep slopes should covered with appropriate soil stabilization matting. April 4, 2002 -l- Blankets and Matting ' Description: Blankets and Martino material can be used as an aid to control erosion on critical sites during the establishment period of protective vegetation. The most common uses are in channels, interceptor swales, diversion dikes, short,steep slopes, and on tidal or stream banks. ' Materials: New types of blankets and matting materials are continuously being developed. The Texas Department of Transportation (TxDOT) has defined the critical performance factors for these types of products and has established minimum performance standards which must be met for any product seeking to be approved " for use within any of TxDOT's construction or maintenance activities. The products that have been approved by TxDOT are also appropriate for general construction site stabilization. TxDOT maintains a web site at http.//www.dotstate.tx.usAnsdtdot/orgchut/cmd/erosion/contents.httm which is updated as new products are evaluated. Installation: , • Install in accordance with the manufacturer's recommendations. • Proper anchoring of the material. • Prepare a friable seed bed relatively free from clods and rocks and any foreign material. • Fertilize and seed in accordance with seeding or other type of planting plan. • Erosion stops should extend beyond the channel liner to full design cross-section of the channel. ., • A uniform trench perpendicular to line of flow may be duo with a spade or a mechanical trencher. • Erosion stops should be deep enough to penetrate solid material or below level of ruling in sandy soils. • Erosion stop mats should be wide enough to allow turnover at bottom of trench for stapling, while maintaining the top edge flush with channel surface. Mulch Description: Mulching is the process of applying a material to the exposed soil surface to protect it from .. erosive forces and to conserve soil moisture until plants can become established. When seeding critical sites,sites with adverse soil conditions or seeding on other than optimum seeding dates,mulch material should be applied immediately after seeding.Seedingducingoptimumseedingdatesandwithfavorablesoiis and site conditions will not need to be mulched. Materials: • Mulch may be small grain straw which should be applied uniformly. • On slopes 15 percent or greater,a binding chemical must be applied to the surface. April 4, 2002 -2- ..• • Wood-fiber or paper-fiber mulch may be applied by hydro seeding. • Mulch netting may be used. • Wood chips may be used where appropriate. Installation: Mulch anchoring should be accomplished immediately after mulch placement. This may be done by one of the following methods:peg and twine,mulch netting,mulch anchoring tool,or liquid mulch binders. Sod Description: Sod is appropriate for disturbed areas which require immediate vegetative covers,or where sodding is preferred to other means of grass establishment. Locations particularly suited to stabilization with sod are waterways carrying intermittent flow, areas around drop inlets or in grassed swales, and residential or commercial lawns where quick use or aesthetics are factors. Sod is composed of living plants and those plants must receive adequate care in order to provide vegetative stabilization on a disturbed area. p Materials: • Sod should be machine cut at a uniform soil thickness. • Pieces of sod should be cut to the supplier's standard width and length. • Tom or uneven pads are not acceptable. • Sections of sod should be strong enough to support their own weight and retain their size and shape when suspended from a firm grasp. • Sod should be harvested,delivered, and installed within a period of 36 hours. Installation: • Areas to be sodded should be brought to final grade. • The surface should be cleared of all trash and debris. • Fertilize according to soil tests. • Fertilizer should be worked into the soil. • Sod should not be cut or laid in excessively wet or dry weather. • Sod should not be laid on soil surfaces that aie frozen. • During periods of high temperature, the soil should be lightly irrigated. April 4, 2002 -3- NEIL EI 9 ✓�.1 • The first row of sod should be laid in a straight line with subsequent rows placed parallel to and butting tightly against each other. • Lateral joints should be staggered to promote more uniform growth and strength. • Wherever erosion may be a problem,sod should be laid with staggered joints and secured- • Sod should be installed with the length perpendicular to the slope (on the contour). • Sod should be rolled or tamped. • Sod should be irrigated to a sufficient depth. • Watering should be performed as often as necessary to maintain soil moisture. • The first mowing should not be attempted until the sod is firmly rooted. _ • Not more than one third of the grass leaf should be removed at any one cutting. Interceptor Swale Interceptor swales are used to shorten the length of exposed slope by intercepting runoff,prevent off-site runoff from entering the disturbed area,and prevent sediment-laden runoff from leaving a disturbed site. They may have a v-shape or be trapezodiai with a fiat bottom and side slopes of 3:1 or flatter. The outflow from a swale should be directed to a stabilized outlet or sediment trapping device. The swales should remain in place until the disturbed area is permanently stabilized. Materials: • Stabilization should consist of a layer of crushed stone three inches thick,riprap or high velocity erosion control mats. • Stone stabilization should be used when grades exceed 2%or velocities exceed 6 feet per second. • Stabilization should extend across the bottom of the swale and up both sides of the channel to a minimum height of three inches above the design water surface elevation based on a 2-year,24-hour storm. -" Installation: • An interceptor swale should be installed across exposed slopes during construction and should intercept no more than 5 acres of runoff. • All earth removed and not needed in construction should be disposed of in an approved spoils site so that it will not interfere pith the functioning of the swale or contribute to siltation in other areas of the site. • All trees, brush,stumps,obstructions and other material should be removed and disposed of so as not to interfere with the proper functioning of the Swale. f April 4, 2002 -4- Swales should have a maximum depth of 1.5 feet with side slopes of 3:1 or flatter.Swales should have positive drainage for the entire length to an outlet. • When the slope exceeds 2 percent, or velocities exceed 6 feet per second (regardless of slope), stabilization is required.Stabilization should be crushed stone placed in a layer of at least 3 inches thick or may be high velocity erosion control matting. Check dams are also recommended to reduce velocities ■. in the stivales possibly reducing the amount of stabilization necessary. • Minimum compaction for the swale should be 90%standard proctor density. Diversion Dikes A temporary diversion dike is a barrier created by the placement of an earthen embankment to reroute the flow of runoff to an erosion control device or away from an open, easily erodible area_A diversion dike intercepts runofffrom small upland areas and diverts it away from exposed slopes to a stabilized outlet,such as a rock berm,sandbag berm,or stone outlet structure.These controls can be used on tht-perimeter of the site to prevent runoff from entering the construction area. Dikes are generally used for the duration of construction to intercept and reroute runoff from disturbed areas to prevent excessive erosion until permanent drainage features are installed and/or slopes are stabilized. Materials: • Stone stabilization (required for velocities in excess of 6 fps) should consist of riprap placed in a layer at least 3 inches thick and should extend a minimum height of 3 inches above the design water surface up the existing slope and the upstream face of the dike. • Geotextile fabric should be a non-woven polypropylene fabric designed specifically for use as a soil filtration media with an approximate weight of 6 oz./yd', a Mullen burst rating of 140 psi,and having an equivalent opening size (EOS) greater than a 7 50 sieve. Installation: • Diversion dikes should be installed prior to and maintained for the duration of construction and should intercept no more than 10 acres of runoff • Dikes should have a minimum top width of 2 feet and a minimum height of compacted fill of 18 inches measured form the top of the existing ground at the upslope toe to top of the dike and have side slopes of .r 3:1 or flatter. • The soil for the dike should be placed in lifts of 8 inches or less and be compacted to 95 % standard proctor density. • The channel,which is formed by the dike,must have positive drainage for its entire length to an outlet. • When the slope exceeds 2 percent, or velocities exceed 6 feet per second (regardless of slope), stabilization is required.In situations where velocities do not exceed 6 feet per second,vegetation may be used to control erosion- April 4, rosion.Apri19, 2002 -5- SEDRAENT CONTROL BMPS Sand Bag Berm Description: The purpose of a sandbag berm is to detain sediment carried in runoff from disturbed areas. This objective is accomplished by intercepting runoff and causing it to pool behind the sand bag berm. Sediment carried in the runoff is deposited on the upstream side of the sand bag berm due to the reduced flow velocity. Excess runoff volumes are allowed to flow over the top of the sand bag berm. Sand bag berms are used only during construction activities in streambeds when the contributing drainage area is between 5 and 10 acres and the slope is less than 15%, i.e., utility construction in channels, temporary channel crossing for construction equipment,etc. Plastic facing should be installed on the upstream side and the berm should be anchored to the streambed by drilling into the rock and driving,in "T"posts or rebar (#5 or 06)spaced appropriately. Materials: • The.sand bag material should be polypropylene,polyethylene,polyimide or cotton burlap woven fabric, minimum unit weight 4 oz/yd 2,mullen burst strength exceeding 300 psi and ultraviolet stability exceeding " 70 percent. • The bag length should be 24 to 30 inches,width should be 16 to 18 inches and thickness should be 6 to 8 inches. • Sandbags should be filled with coarse grade sand and free from deleterious material. All sand should pass through a No. 10 sieve. The filled bag should have an approximate weight of 40 pounds. • Outlet pipe should be schedule 40 or stronger polyvinyl chloride (PVC) having a nominal internal diameter of 4 inches. Installation: - The berm should be a minimum height of 18 inches,measured from the top of the existing ground at the upslope toe to the top of the berm. - • The berm should be sized as shown in the plans but should have a minimum width of 48 inches measured at the bottom of the berm and 16 inches measured at the top of the berm. • Runoff water should flow over the tops of the sandbags or through 4-inch diameter PVC pipes embedded below the top layer of bags. • When a sandbag is filled with material,the open end of the sandbag should be stapled or tied with nylon or poly cord_ • Sandbags should be stacked in at least three rows abutting each other, and in staggered arrangement. • The base of the berm should have at least 3 sandbags. These can be reduced to 2 and 1 bag in the second and third rows respectively. April 4, 2002 -6- • For each additional 6 inches of height, an additional sandbag must be added to each row width. • A bypass pump-around system,or similar alternative,should be used on conjunction with the berm for t effective dewatering of the work area. Silt Fence Description: A silt fence is a barrier consisting of geotextile fabric supported by metal posts to prevent soil and sediment loss from a site. When properly used, silt fences can be highly effective at controlling •" sediment from disturbed areas. They cause runoff to pond which allows heavier solids to settle. If not properly installed,silt fences are not likely to be effective. The purpose of a silt fence is to intercept and detain water-borne sediment from unprotected areas of a limited extent. Silt fence is used during the period of construction near the perimeter of a disturbed area to intercept sediment while allowing water to percolate through. This fence should remain in place until the disturbed area is permanently stabilized. Silt fence should not be used where there is a concentration of water in a channel or drainage way. If concentrated flow occurs after installation,corrective action must be taken such as placing a rock berm in the areas of concentrated flow. Silt fencing within the site may be temporarily moved during the day to allow construction activity provided it is replaced and properly anchored to the ground at the end of the day. Silt fences on the perimeter of the site or around drainage ways should not be moved at any time. Materials: • Silt fence material should be polypropylene,polyethylene or polyamide woven or nonwoven fabric. The fabric width should be 36 inches,with a minimum unit weight of 4.5 ozlyd,mullen burst strength exceeding - 190 lb/tn 2,ultraviolet stability exceeding 7096,and minimum apparent opening she of U.S.Sieve No.30. • Fence posts should be made of hot rolled steel, at least 4 feet lona with Tee or Y-bar cross section, surface painted or galvanized,minimum nominal weight 1.25 lb/ft 2,and Brindell hardness exceeding 140. • Woven wire backing to support the fabric should be galvanised 2'x 4"welded wire, 12 gauge minimum. Installation: • Steel posts, which support the silt fence, should be installed on a slight angle toward the anticipated runoff source. Post must be embedded a minimum of 1 foot deep and spaced not more than 8 feet on center. Where water concentrates, the maximum spacing should be 6 feet. • Lay out fencing down-slope of disturbed area, following the contour as closely as possible.The fence should be sited so that the maximum drainage area is %acre/100 feet of fence. • The toe of the silt fence should be trenched in with a spade or mechanical trencher,so that the down- slope face of the trench is flat and perpendicular to the line of flow. Where fence cannot be trenched in (e.g.,pavement or rock outcrop),weight fabric flap with 3 inches of pea gravel on uphill side to prevent flow from seeping under fence. -,, The trench must be a minimum of 6 inches deep and 6 inches wide to allow for the silt fence fabric to be laid in the ground and backfilled with compacted material. April 4, 2002 -7- • Silt fence should be securely fastened to each steel support post or to woven wire, which is in turn attached to the steel fence post. There should be a 3-foot overlap,securely fastened where ends of fabric meet. Trian--ular Filter Dike Description: The purpose of a triangular sediment filter dike is to intercept and detain water-borne sediment from unprotected areas of limited extent. The triangular sediment filter dike is used where there is no concentration of water in a channel or other drainage way above the barrier and the contributing drainage area is less than one acre. If the uphill slope above the dike exceeds 10%,the length of the slope above the dike should be less than 50 feet. If concentrated flow occurs after installation,corrective action should be taken such as placing rock berm in the areas of concentrated flow. This measure is effective on paved areas where installation of silt fence is not possible or where vehicle access must be maintained.The advantage of these controls is the ease with which they can be moved to allow vehicle traffic and then reinstalled to maintain sediment Materials: • Silt fence material should be polypropylene,polyethylene or polyamide woven or nonwoven fabric The fabric width should be 36 inches,with a minimum unit weight of4.5 oz4A mullen burst strength exceeding 190 lbtm 2,ultraviolet stability exceeding 70%,and minimum apparent opening sire of U.S.Sieve No.30: • The dike structure should be 6 gauge 6"x 6"wire mesh folded into triangular form being eighteen(18) inches on each side. Installation: • The frame of the triangular sediment filter dike should be constructed of 6"x 6",6 gauge welded wire mesh, 18 inches per side, and wrapped with geotextile fabric the same composition as that used for silt fences. • Filter material should lap over ends six (6)inches to cover dike to dike junction;each junction should be secured by shoat rings. • Position dike parallel to the contours,with the end of each section closely abutting the adjacent sections. • There are several options for fastening the filter dike to the ground.The fabric skirt may be toed-in with 6 inches of compacted'material,or 12 inches of the fabric skirt should extend uphill and be secured with a minimum of 3 inches of open graded rock,or with staples or nails. If these two options are not feasible' the dike structure may be trenched in 4 inches. • Triangular sediment filter dikes should be installed across exposed slopes during construction with ends of the dike tied into existing grades to prevent failure and should intercept no more than one acre of runoff. • When moved to allow vehicular access,the dikes should be reinstalled as soon as possible, but always at the end of the workday. April 4, 2002 -8- Rock Berm Description. The purpose of a rock berm is to serve as a check dam in areas of concentrated flow, to intercept sediment-laden runoff,detain the sediment and release the water in sheet flow. The tock berm should be used when the contributing drainage area is less than 5 acres. Rock berms are used in areas where the volume of runoff is too great for a silt fence to contain. They are less effective for sediment removal than silt fences, particularly for fine particles,but are able to withstand higher flows than a silt fence. As such,rock berms are often used in areas of channel flows (ditches,gullies,etc.). Rock berms are most effective at reducing bed load in channels and should not be substituted for other erosion and sediment control measures further up the watershed. Materials: • The berm structure should be secured with a woven wire sheathing having maximum opening of 1 inch and a minimum wire diameter of 20 gauge galvanized and should be secured with shoat rings. • Clean,open graded 3=to 5-inch diameter rock should be used,except in areas where high velocities or large volumes of flow are expected,where 5- to 8-inch diameter rocks may be used. Installation: • Lay out the woven wire sheathing perpendicular to the flow line. The sheathing should be 20 gauge woven wire mesh with 1 inch openings. • Berm should have a top width of 2 feet minimum with side slopes being 2:1 (H:V) or flatter. • Place the rock along the sheathing to a height not less than 18". • Wrap the wire sheathing around the rock and secure with tie wire so that the ends of the sheathing overlap at least 2 inches, and the berm retains its shape when walked upon. • Berm should be built along the contour at zero percent grade or as near as possible. • The ends of the berm should be tied into existing upslope grade and the berm should be buried in a trench approximately 3 to 4 inches deep to prevent failure of the control. Hay Bale Dike Description: The purpose of a hay or straw bale dike is to intercept and detain small amounts of sediment- - laden runoff from relatively small unprotected areas. Straw bales are to be used when it is not feasible to install other, more effective measures or when the construction phase is expected to last less than 3 months. Straw bales should not be used on areas where rock or other hard surfaces prevent the full and uniform anchoring of the barrier. Materials: Straw: The best quality straw mulch comes from wheat,oats or barley and should be free of weed and grass seed which may not be desired vegetation for the area to be protected. Straw mulch is light and therefore •. must be properly anchored to the ground. April 4, 2002 -9- Hay: This is very similar to straw with the exception that iris made of grasses and weeds and not grain stems. This form of mulch is very inexpensive and is widely available but does introduce weed and grass seed to the area. Like straw,hay is light and must be anchored. • Straw bales should weigh a minimum of 50 pounds and should be at least 30 inches lona. • Bales should be composed entirely of vegetable matter and be free of seeds. • Binding should be either wire or nylon string,jute or cotton binding is unacceptable. Bales should be used for not more than two months before being replaced. Installation: • Bales should be embedded a minimum of 4 inches and securely anchored using 2"x 2"wood stakes or 3/8"diameter rebar driven through the bales into the ground a minimum of 6 inches. • Bales are to be placed directly adjacent to one another leaving no gap between them. - • All bales should be placed on the contour. • The first stake in each bale should be angled toward the previously laid bale to force the bales together: Brush Berne Organic litter and spoil material from site clearing operations is usually burned or hauled away to be dumped elsewhere.Much of this material can be used effectively on the construction site itself. The key to constructing an efficient brush berm is in the method used to obtain and place the brush.It will not be acceptable to simply take a bulldozer and push whole trees into a pile. This method does not assure continuous ground contact with the berm and will allow uncontrolled flows under the berm. Brush berms maybe used where there is little or no concentration of water in a channel or other drainage way above the berm.The sine of the drainage area should be no greater than one-fourth of an acre per 140 feet of barrier length; the maximum slope length behind the barrier should not exceed 100 feet; and the maximum slope gradient behind the barrier should be less than 50 percent (2:1). Materials: • The brush should consist of woody brush and branches,preferably less than 2 inches in diameter. • The filter fabric should conform to the specifications for filter fence fabric. • The rope should be %inch polypropylene or nylon rope. • The anchors should be 3/8-inch diameter rebar stakes that are 18-inches long. Installation: • Lay out the brush berm following the contour as closely as possible. April 4. 2002 -10- • The juniper limbs should be cut and hand placed with the vegetated part of the limb in close contact with the ground.Each subsequent branch should overlap the previous branch providing a shingle effect. • The brush berm should be constructed in lifts with each layer extending the entire length of the berm before the next layer is started. • A trench should be excavated 6-inches wide and 4-inches deep along the length of the barrier and immediately uphill from the barrier. • The filter fabric should be cut into lengths sufficient to lay across the barrier from its up-slope base to just beyond its peak.The lengths of filter fabric should be draped across the width of the barrier with the uphill edge placed in the trench and the edges of adjacent pieces overlapping each other.Where joints are necessary, the fabric should be spliced together with a minimum 6-inch overlap and securely sealed. • The trench should be backfilled and the soil compacted over the filter fabric. • Set stakes into the ground along the downhill edge of the brush barrier,and anchor the fabric.by tying rope from the fabric to the stakes. Drive the rope anchors into the ground at approximately a 45-degree angle to the ground on 6-foot centers. • Fasten the rope to the anchors and tighten berm securely to the ground with a minimum tension of 50 pounds. • The height of the brush berm should be a minimum of 24 inches after the securing ropes have been tightened. Stone Outlet Sediment Trap A stone outlet sediment trap is an impoundment created by the placement of an earthen and stone embankment to prevent soil and sediment loss from a site.The purpose of a sediment trap is to intercept sediment-laden runoffand trap the sediment in order to protect drainage ways,properties and rights of way below the sediment trap from sedimentation.A sediment trap is usually installed at points of discharge from disturbed areas.The drainage area for a sediment trap is recommended to be less than 5 acres. Larger areas should be treated using a sediment basin.A sediment trap differs from a sediment basin mainly in the type of discharge structure. The trap should be located to obtain the maximum storage benefit from the terrain,for ease of clean out and disposal of the trapped sediment and to minimize interference with construction activities.The volume of the trap should be at least 3600 cubic feet per acre of drainage area. -- Materials: • All aggregate should be at test 3 inches in diameter and should not exceed a volume of 0.5 cubic foot. • The geotextile fabric specification should be woven polypropylene,polyethylene or polyamide geotextile, minimum unit weight of 4.5 oz/yd 2, multen burst strength at least 250 1bftn 2, ultraviolet stability exceeding 70%, and equivalent opening size exceeding 40. Installation: April 4, 2002 -11- • Earth Embankment: Place fill material in layers not more than 8 inches in loose depth: Before compaction, moisten or aerate each layer as necessary to provide the optimum moisture content of the material.Compact each layer to 95 percent standard proctor density.Do not place material on surfaces that are muddy or frozen. Side slopes for the embankment are to be 3:1. The minimum width of the embankment should be 3 feet. • A gap is to be left in the embankment in the location where the natural confluence of runoff crosses the embankment line.The gap is to have a width in feet equal to 6 times the drainage area in acres. • Geotextile Covered Rock Core: A core of filter stone having a minimum height of 1.5 feet and a minimum width at the base of 3 feet should be placed across the opening of the earth embankment and should be covered by geotextile fabric which should extend a minimum distance of l feet in either direction from the base of the filter stone core. .- • Filter Stone Embankment. Filter stone should be placed over the geotextile and is to have a side slope which matches:that of the earth embankment of 3:1 and should cover the geotextile/rock core a minimum of 6 inches when installation is complete.The crest of the outlet should be at least 1 foot below the top of the embankment. Sediment Basins: The purpose of a sediment basin is to intercept sediment-laden runoff and trap the sediment in order to protect drainage ways, properties and rights of way below the sediment basin from sedimentation. A sediment basin is usually installed at points of discharge from disturbed areas.The drainage area for a sediment basin is recommended to be less than 100 acres. Sediment basins are effective for capturing and slowly releasing the runoff from larger disturbed areas thereby allowing sedimentation to take place.A sediment basin can be created where a permanent pond BMP is being constructed. Guidelines for construction of the permanent BMP should be followed, but revegetation,placement of underdrain piping,and installation of sand or other filter media should not be carried out until the site construction phase is complete. Materials: • Riser should be corrugated metal or reinforced concrete pipe or box and should have watertight fittings or end to end connections of sections. • An.outlet pipe of corrugated metal or reinforced concrete should be attached to the riser and should have positive flow to a stabilized outlet on the downstream side of the embankment. • An anti-vortex device and rubbish screen should be attached to the top of the riser and should be made of polyvinyl chloride or corrugated metal. Basin Design and Construction: • For common drainage locations that serve an area with ten or more acres disturbed at one time, a sediment basin should provide storage for a volume of runoff from a two-year, 24-hour storm from each disturbed acre drained. • The basin length to width ratio should be at least 2:1 to improve trapping efficiency.The shape may be Anri14 ?nn? -12- attained by excavation or the use of baffles.The lengths should be measured at the elevation of the riser de-watering hole. • Place fill material in layers not more than 8 inches in loose depth.Before compaction,moisten or aerate each layer as necessary to provide the optimum moisture content of the material.Compact each layer to 95 percent standard proctor density.Do not place material on surfaces that are muddy or frozen.Side slopes for the embarikment should be 3:1 (H:). • An emergency spillway should be installed adjacent to the embankment on undisturbed soil and should be sized to carry the full amount of flow generated by a 10-year,3-hour storm with 1 foot of freeboard less the amount which can be carried by the principal outlet control device. • The emergency spillway should be lined with riprap as should the swale leading from the spillway to the normal watercourse at the base of the embankment. • The principal outlet control device should consist of a rigid vertically oriented pipe or box of corrugated metal or reinforced concrete.Attached to this structure should be a horizontal pipe,which should extend through the embankment to the toe of fill to provide a de-watering outlet for the basin. • An anti-vortex device should be attached to the inlet portion of the principal outlet control device to, serve as a rubbish screen. • A concrete base should be used to anchor the principal outlet control device and should be sized to provide a safety factor of 1.5 (downward forces = 1.5 buoyant forces). • The basin should include a permanent stake to indicate the sediment level in the pool and marked to indicate when the sediment occupies 50%of the basin volume (not the top of the stake). • The top of the riser pipe should remain open and be guarded with a trash rack and anti-vortex device. The top of the riser should be 12 inches below the elevation of the emergency spillway.The riser should be sized to convey the runoff from the 2-year,3-hour storm when the water surface is at the emergency spillway elevation. For basins with no spillway the riser must be sized to convey the runoff from the 10-yr, 3-hour storm. • Anti-seep collars should be included when soil conditions or length of service make piping through the backfill a possibility. • The 48-hour drawdown time will be achieved by using a riser pipe perforated at the point measured from the bottom of the riser pipe equal to %z the volume of the basin.This is the maximum sediment storage elevation.The sLe of the perforation may be calculated as follows: -° AS x f2h _ A° C,x 980,000 Where: Ao = Area of the de-watering hole, ft 2hV 'd April 4, 2002 -13- As = Surface area of the basin,ft 2 Cd = Coefficient of contraction,approximately 0.6 . h = head of water above the hole, ft Perforating the riser with multiple holes with a combined surface area equal to Ao is acceptable. POST-CONSTRUCTION TSS CONTROLS Retention/1r i-ation Systems Description: Retention/irrigation systems refer to the capture of runoffin a holding pond,then use of the captured water for irrigation of appropriate landscape areas. Retention/urigation system's are characterized by the capture and disposal of runoff without direct release of captured flow to receiving streams. Retention systems exhibit excellent pollutant removal but can require regular, proper maintenance. Collection of roof runoff for subsequent use (rainwater harvesting) also qualifies as a retention/urigation practice,but should be operated and sized to provide adequate volume.This technology,which emphasizes beneficial use of stormwater runoff, is particularly appropriate for and regions because of increasing demarids on water supplies for agricultural irrigation and urban water supply. - Design Considerations: Retention/Irrigation practices achieve 100%removal efficiency oftotal suspended solids contained within the volume of water captured. Design elements of retention/irrigation systems- include runoffstorage facilityconfiguration and sizing,pump and wet well system components,basin lining, basin detention time, and physical and operational components of the irrigation system. Retention/urigation systems are appropriate for large drainage areas with low to moderate slopes. The retention capacity should be sufficient considering the average rainfall event for the area. CP Maintenance Requirements: Maintenance requirements for retention/rrnigation systems include routine inspections,sediment removal,mowing,debris and litter removal,erosion control,and nuisance control. Extended Detention Basin Description: Extended detention facilities are basins that temporarily store a portion of stormwater runoff following a storm event. Extended detention basins are normally used to remove particulate pollutants and to reduce maximum runoff rates associated with development to their pre-development levels. The water quality benefits are the removal of sediment and buoyant materials. Furthermore,nutrients,heavy metals, toxic materials, and oxygen-demanding materials associated with the particles also are removed. The control of the maximum runoff rates serves to protect drainage channels below the device from erosion and to reduce downstream flooding. Although detention facilities designed for flood control have different design requirements than those used for water quality enhancement, it is possible to achieve these two objectives in a single facility. Design Considerations: Extended detention basins can remove approximately 75%of the total suspended solids contained within the volume of runoff captured in the basin. Design elements of extended detention basins include basin sizing,basin configuration,basin side slopes,basin lining,inlet/outlet structures,and erosion controls. Extended detention basins are appropriate for large drainage areas with low to moderate slopes. The retention capacity should be sufficient considering the average rainfall event for the area. April 4, 2002 -14- Maintenance Requirements: Maintenance requirements for extended detention basins include routine inspections, mowing,debris and litter removal, erosion control,structural repairs,nuisance control,and sediment removal. Vegetative Filter Strips Description: Filter strips,also known as vegetated buffer strips, are vegetated sections of land similar to grassy swales, except they are essentially flat with low slopes, and are designed only to accept runoff as overland sheet flow. They may appear in any vegetated form from grassland to forest,and are designed to intercept upstream flow, lower flow velocity, and spread water out as sheet flow.The dense vegetative cover facilitates conventional pollutant removal through detention, filtration by vegetation, and infiltration. Filter strips cannot treat high velocity flows,and do not provide enough storage or infiltration to effectively reduce peak discharges to predevelopment levels for design storms.This lack of quantity control favors use in rural or low-density development; however, they can provide water quality benefits even where the impervious cover is as high as 50%.The primary highway application for vegetative filter strips is along rural roadways where runoff that would otherwise discharge directly to a receiving water, passes through the filter strip before entering a conveyance system. Properly designed roadway medians and shoulders make effective buffer strips.These devices also can be used on other types of development where land is available and hydraulic conditions are appropriate. Flat slopes and low to fair permeability of natural subsoil are required for effective performance of filter strips.Although an inexpensive control measure,they are most useful in contributing watershed areas where peak runoff velocities are low,as they are unable to treat the high floe velocities typically associated with high impervious cover. The most important criteria for selection and use of this BMP are soils,space, and slope. Design Considerations: Vegetative filter strips can remove approximately 85%of the total suspended solids contained within the volume of runoff captured. Design elements of vegetative filter strips include uniform,shallow overland flow across the entire filter strip area, hydraulic loading rate,inlet structures, slope, and vegetative cover. The area should be free of gullies or rills which can concentrate flow. - Vegetative filter strips are appropriate for small drainage areas with moderate slopes. Maintenance Requirements: Maintenance requirements for vegetative filter strips include pest management, seasonal mowing and lawn care, routine inspections, debris and litter removal, sediment removal, and grass reseeding and mulching. Constructed Wetlands Description: Constructed wetlands provide physical,chemical,and biological water quality treatment of stormwater runoff. Physical treatment occurs as a result of decreasing flow velocities in the wetland,and is present in the form of evaporation, sedimentation, adsorption, and/or filtration. Chemical processes include chelation, precipitation, and chemical adsorption. Biological processes include decomposition, plant uptake and removal of nutrients,plus biological transformation and degradation. Hydrology is one of the most influential factors in pollutant removal due to its effects on sedimentation,aeration,biological transformation, and adsorption onto bottom sediments. The wetland should be designed such that a minimum amount of maintenance is required. The natural surroundings,including such things as the potential energy of a stream or flooding river,should be utilized April 4, 2002 -15- as much as possible. The wetland should approximate a natural situation and unnatural attributes,such as rectangular shape or rigid channel,should be avoided. Site considerations should include the water table depth,soil/substrate,and space requirements.Because the wetland must have a source of flow,it is desirable that the water table is at or near the surface. If runoff is the onlysource ofinflow for the wetland,the water level often fluctuates and establishment of vegetation may be difficult. The soil or substrate of an artificial wetland should be loose loam to clay. A perennial baseflow must be present to sustain the artificial wedand. The presence of organic material is often helpful in increasing pollutant removal and retention. A greater amount of space is required for a wetland system than is required for a detention facility treating the same amount of area. Design Considerations: Constructed wetlands can remove over 90% of the total suspended solids contained within the volume of runoff captured in the wetland. Design elements of constructed wetlands include wetland sizing,wetland configuration,sediment forebay,vegetation, outflow structure,depth of inundation duringstorm events,depth of micropools,and aeration. Constructed wetlands are appropriate for large drainage areas with low to moderate slopes. Maintenance Requirements: Maintenance requirements for constructed wetlands include mowing, routine inspections,debris and litter removal,erosion control,nuisance control,structural repairs,sediment removal,harvesting,and maintenance of water levels. Wet Basins Description: Wet basins are runoff control facilities that maintain a permanent wet pool and a standing crop of emergent littoral vegetation. These facilities may vary in appearance from natural ponds to enlarged,termed(manmade)sections of drainage systems and may function as online or offline facilities, although offline configuration is preferable. Offline designs can prevent scour and other damage to the wet pond and minimize costly outflow structure elements needed to accommodate extreme runoff events. During storm events,runoff inflows displace part or all of the existing basin volume and are retained and treated in the facility until the next storm event. The pollutant removal mechanisms are settling of solids, wetland plant uptake, and microbial degradation. When the wet basin is adequately sized, pollutant removal performance can be excellent,especially for the dissolved fraction. Wet basins also help provide erosion protection for the receiving channel by limiting peak flows during larger storm events. Wet basins are often perceived as a positive aesthetic element in a community and offer significant opportunity for creative pond configuration and landscape design. Participation of an experienced wetland designer is suggested. A significant potential drawback for wet ponds in and climates is that the contributing watershed for these facilities is often incapable of providing an adequate water supply to maintain the .� permanent pool, especially during the summer months. Makeup water (i.e., well water or municipal drinking water) is sometimes used to supplement the rainfalVrunoff process, especially for wet basin facilities treating watersheds that generate insufficient runoff. Design Considerations: Wet basins can remove over 90%of the total suspended solids contained within the volume of runoff captured in the basin. Design elements of wet basins include basin sizing, basin configuration, basin side slopes, sediment forebay, inflow and outflow structures, vegetation, depth of permanent pool, aeration, and erosion control. Wet basins are appropriate for large drainage areas with low to moderate slopes. April 4, 2002 -16- Maintenance Requirements: Maintenance requirements for wet basins include mowing, routine inspections, debris and litter removal, erosion control, nuisance control, structural repairs, sediment removal, and harvesting. Grassy Swales Grassy swales are vegetated channels that convey stormwater and remove pollutants by filtration through grass and infiltration through soil.They require shallow slopes and soils that drain well.Pollutant removal capability is related to channel dimensions,longitudinal slope,and type of vegetation.Optimum design of these components will increase contact time of runoff through the swale and improve pollutant removal rates-Grassy swales are primarilystormwater conveyance systems.They can provide sufficient control under light to moderate runoff conditions,but their ability to control large storms is limited.Therefore,they are most applicable in low to moderate sloped areas or along highway medians as an alternative to ditches and curb and gutter drainage.Their performance diminishes sharply in highly urbanized settings, and they are generally not effective-enough to receive construction stage runoff where high sediment loads can overwhelm the system.Grassy swales can be used as a pretreatment measure for other downstream BMPs, such as extended detention basins_ Enhanced grassy swales utilize check dams and wide depressions to increase runoff storage and promote greater settling of pollutants. Grassy swales can be more aesthetically pleasing than concrete or rock-lined drainage systems and are generally less expensive to construct and maintain.Swales can slightly reduce impervious area and reduce the pollutant accumulation and delivery associated with curbs and gutters. The disadvantages of this technique include the possibility of erosion and channelization over time,and the need for more right-of- way as compared to a storm drain system.When properly constructed,inspected,and maintained,the life expectancy of a swale is estimated to be 20 years. Design Considerations: - Comparable performance to wet basins - limited to treating a few acres - Availability of water during dry periods to maintain vegetation CP - Sufficient available land area The suitability of a swab at a site will depend on land use, size of the area serviced, soil type, slope, imperviousness of the contributing watershed,and dimensions and slope of the swale system.In general, swales can be used to serve areas of less than 10 acres,with slopes nob eater than S%.The seasonal high water table should be at least 4 feet below the surface.Use of natural topographic lows is encouraged,and natural drainage courses should be regarded as significant local resources to be kept in use. Maintenance Requirements: Research in the Austin area indicates that vegetated controls are effective at removing pollutants even when dormant.Therefore, irrigation is not required to maintain growth during dry periods,but may be April 4, 2002 -17- necessary only to prevent the vegetation from dying. Vegetative Filter Strias Filter strips, also known as vegetated buffer strips, are vegetated sections of land similar to grassy.swales except they are essentially flat with low slopes,and are designed only to accept runoff as overland sheet flow.A schematic of a vegetated buffer strip is shown in Figure 33.They may appear in any vegetated form from grassland to forest;and are designed to intercept upstream flow,lower flow velocity,and spread water out as sheet flow.The dense vegetative cover facilitates conventional pollutant removal through detention, filtration by vegetation, andutfiltration. Filter strips cannot treat high velocity flows,and do not provide enough storage or infiltration to effectively reduce peak discharges to predevelopment levels for design storms.This lack of quantity control favors use in rural or low-density development; however, they can provide water quality benefits even where the impervious cover is as high as 50%.The primary highway application for vegetative filter strips is along rural roadways where runoffthat would otherwise discharge directly to a receiving water passes through the filter strip before entering a conveyance system.Properlydesigned roadway -medians and shoulders make effective buffer strips.These devices also can be used on other types of development where land is available and hydraulic conditions are appropriate. Flat slopes and low to fair permeability of natural subsoil are required for effective performance of filter strips. Although an inexpensive control measure, they are most useful in contributing watershed areas where peak runoff velocities are low as they are unable to treat the high flow velocities typically associated with high impervious cover. Successful performance of filter strips relies heavily on maintaining shallow unconcentrated flow.To avoid flow channelization and maintain performance,a filter strip should: • Be equipped with a level spreading device for even distribution of runoff • Contain dense vegetation with a mix of erosion resistant,soil binding species • Be graded to a uniform, even and relatively low slope • Laterally traverse the contributing runoff area Filter strips can be used upgradient from watercourses,wetlands,or other water bodies along toes and tops of slopes and at outlets of other stormwater management structures.They should be incorporated into street drainage and master drainage planning.The most important criteria for selection and use of this BMP are soils,space,and slope. Design Considerations: • Soils and moisture are adequate to grow relatively dense vegetative stands CP • Sufficient space is available • Slope is less than 12% April 4. 2002 '18- , • Comparable performance to more expensive structural controls Sand Filter Systems The objective of sand filters is to remove sediment and the pollutants from the first flush of pavement and impervious area runoff.The filtration of nutrients,organics, and coliform bacteria is enhanced by a mat of bacterial slime that develops during normal operations.One of the main advantages of sand filters is their adaptability;they can be used on areas with thin soils,high evaporation rates,low-soil infiltration rates,in limited-space areas, and where groundwater is to be protected. Since their original inception in Austin, Texas, hundreds of intermittent sand filters have been implemented to treat stormwater runoff:There have been numerous alterations or variations in the original design as engineers in other jurisdictions have improved and adapted the technology to meet their specific requirements.Major types include the Austin Sand Filter, the District of Columbia Underground Sand Filter, the Alexandria Dry Vault Sand Filter, the Delaware Sand Filter, and peat-sand filters which are adapted,to provide a sorption layer and vegetative cover to various sand filter designs. Design Considerations: • Appropriate for space-limited areas • Applicable in and climates where wet basins and constructed wetlands are not appropriate • High TSS removal efficiency Cost Considerations: Filtration Systems may require less land than some other BMPs, reducing the land acquisition cost; howevr the structure itself is one of the more expensive BMPs. In addition,maintenance cost can be substantial.

TMI No.FE02-169 February,2003 --__=— Consulting—Geotechnical-Environmental Construction Materials Testing 1.0 PROJECT DESCRIPTION, PURPOSE AND SCOPE The project consists of the installation of 72-inch and 90-inch diameter, 23,000 foot long sanitary sewer pipeline. The sanitary sewer main alignment is generally located from the Village Creek WWTP south to West Division Street (Highway 80). The project includes about 33 manhole structures and 16 to 20 other major structures including siphons and special boxes. Five long sewer bores are presently planned at the following locations: along Meadowbrook Boulevard and beneath Village Creek, 1-30, Dottie Lynn Parkway and West Division Street. These bore locations could be accomplished by pipe jacking or tunneling. The bottom of the pipe and/or manholes varies from 15 to 27 feet deep in open cut trenches and from 20 to 53 feet deep in the bore locations. The sewer mains are expected to consist of fiberglass pipe or concrete rigid-pipe. The investigation was designed to explore subsurface conditions along the proposed pipeline alignment, and from the results of the exploration, develop engineering parameters and recommendations to be used in its design and construction. Our services included: • A detailed description of subsurface and groundwater conditions at the project site, and their effect on design and construction, including a description of the soil stratigraphy, underlying rock formation, and any noteworthy geological conditions. • The effects of groundwater on the design and installation of the project elements. • Recommendations regarding pipe embedment and trench construction. • Recommendations for pipe design including deflection and modulus of subgrade reaction; and • Corrosion potential of subgrade materials. 2.0 FIELD AND LABORATORY INVESTIGATIONS Subsurface conditions were evaluated by a total of 16 borings drilled from October 20, 2002 to January 7, 2003 to depths of 21 to 60 feet below the existing grades. Approximate boring locations are indicated on the Plan of Borings, Figure 1. A detailed description of the field and laboratory procedures used in the drilling and testing of the soil samples can be found in the Appendix. The results of the field and laboratory testing procedures, along with the soil classification by the Unified Soil Classification System, can be found at the appropriate depths on the Logs of Borings, Page 1 of 19 Sanitary Sewer Main 442 ReAef;Fort Worth,Texas TERRA-MAR, /NC. TMI No.FE02-169 February,2003 Consulting—Geotechnical-Environmental Construction Materials Testing Figures 2 through 21. A key to the boring log terms and symbols is presented on Figures 22 and 23. Results of sieve analysis tests are presented on Figures 24 and 25. 3.0 SITE AND SUBSURFACE CONDITIONS 3.1 Site Geology According to the Dallas Sheet of the Geologic Atlas of Texas, the proposed alignment is geologically located in the Woodbine Formation of the Upper Cretaceous Age. The overburden soils are Alluvial and Terrace deposits associated with the flood plain of the Trinity River and Village Creek. The Woodbine Formation, in its unweathered state, consists primarily of shale, cemented sand and extremely hard sandstone boulders. Significant groundwater seepage can be encountered in the Woodbine, Alluvial and Terrace deposits, particularly in the more granular materials. 3.2 General Stratigraphy .- The stratigraphy along the alignment was noted as being variable, due mainly to the length of the alignment and changes in geology along the project alignment. This makes a broad generalization of the subsurface conditions for the entire project difficult. Therefore, we have provided generalized subsurface conditions for the following segments of the alignment: Borings B-1 through B-6, B-10 and B-16: These borings were typically characterized by the presence of clays with some silty and sandy clays and occasional sands and gravel. The clays were generally dark brown, dark gray, brown and gray and contained sand and calcareous nodules. These soils were fill in Borings B-1, B-4, B-6 and B-16 above depths of 2 to 7 feet. They had Liquid Limits (LL) varying from 52 to 65 percent and Plasticity Indices (PI) varying from 35 to 44 and classified as CH by the Unified Soil Classification System (USCS). The silty and sandy clays were generally brown, tan and gray with LL's varying from 29 to 49 percent and PI's varying from 16 to 32 and classified as CL by the USCS. Dense reddish brown sands with clay and gravel were encountered in Boring B-1 between the depths of 18 and 24 feet and were underlain by tan and gray shaley clays. Borings B-1, B-3, B-4 and B-16 were terminated in the clays and silty clays at depths of 29 to 47 feet. Page 2 of 19 Sanitary Sewer Main 442 Relief.fort Worth,Texas TERRA-MAR, INC. TMI No.FE02-169 _ February,2003 — Consulting—Geotechnical-Envirorwnental Construction Materials Testing Gray shale was present in Borings B-5 and B-6 at a depth of about 18 feet and continued to termination at depths of 25 to 26 feet. Gray shale was encountered in Boring B-2 at a depth of 38 feet and continued to termination at a depth of 50 feet. Borings B-7, B-8& B-9, and B-11 through B-15: The subsurface conditions in this portion of the alignment were typically characterized by silty and sandy clays with some layers of clays and sands. The silty and sandy clays were dark brown, brown and reddish brown in color near the surface and became brown, tan and gray in color with depth. Brown, reddish brown and tan sands and clayey sands were present near the surface in Borings B-7 and B-9 extending to depths of 17 and 31 feet, respectively, and in Boring B-8 between the depths of 26 and 41 feet. Boring B-9 was terminated in the sands at a depth of 31 feet. The sands were underlain by clays in Boring B-7 and by shale in Boring B-8 at a depth of 41 feet, which continued to boring termination at a depth of 60 feet. Shale was also encountered in Boring B-12 at a depth of 11 feet and continued to termination at a depth of 26 feet. The remaining borings were terminated in the various sandy and silty clays at depths of 21 to 55 feet. The sandy and silty clays had LL's varying from 19 to 47 percent and PI'S varying from 6 to 30 and classified as CL by the USCS. The clays had LL's varying from 50 to 71 percent and Pi's varying from 31 to 41 percent and classified as CH by the USCS. 3.3 Groundwater The borings were advanced using continuous fight augers which allows relatively accurate measurement of seepage during drilling. Groundwater seepage was encountered during drilling in all the borings, except in Borings B-4, B-6, B-11, B-12 and B-15, at depths ranging from 8.5 to 38 feet below existing grade. Water levels at completion were typically measured within a few feet of the observed seepage levels. .. It is not possible to accurately predict the magnitude of subsurface water fluctuation that might occur based upon these short-term observations, and it should be recognized that groundwater levels will fluctuate with variations in seasonal precipitation and 'surficial runoff. However, we anticipate that groundwater levels near the observed levels will be present throughout the year where the granular materials are present. If there is a noticeable change from the conditions reported herein, Terra-Mar should be notified immediately to review the effects it may have on the design.

Approximately 5,100 feet will be constructed using bores for the various crossings and about 820 feet will be constructed using a siphon structure. The trench excavations will generally extend to depths on the order of 15 to 27 feet. The bore locations typically extend to depths of 20 to 28 feet except for the long bore beneath Meadowbrook Boulevard, which extends up to 53 feet below grade. The approximate excavation depths, manhole depth and anticipated soil conditions at each boring location are summarized in the following Table 1 TABLE 1 —ANTICIPATED SOIL CONDITIONS AT THE PIPE ELEVATION STATION BORING STRUCTURE ANTICIPATED STRATA NO.

For excavations less than 5 feet deep through the Page 4 of 19 Sanitary Sewer Main 442 Relief.Fort Worth.Texas �_ TERRA-MAR, INC. TMI No.FE02-169 February.2003 =_— Consulting—Geotechnical-Environmental Constriction Materials Testing various clays, silty clays and sandy clays, it is expected that near vertical excavation walls will be possible. However, for excavations through soft clays, granular soils, non-compacted fill, or submerged soil it will be necessary to either slope the excavation sidewalls or provide temporary bracing to control excavation wall instability. In addition, for excavations deeper than 5 feet, the excavation sidewalls must be sloped or temporary bracing must be provided, regardless of the soil conditions encountered. According to OSHA standards, the stiff to hard naturally occurring clays are classified as Type A - deposits and the silty and sandy clays are classified as Type B deposits. The granular soils, soft clays, non-compact fills, and soils which occur below the groundwater table or through which seepage water is encountered, are classified as Type C deposits. Excavated slopes should be no steeper than 1HAV in clays above the groundwater level, or 2HAV in granular soils and submerged soil conditions. A 2HAV slope is recommended in clays overlying sands. For sloped excavations, surcharge loads, such as those resulting from excavation spoil or equipment should be placed no closer than 2 feet from the crest of the slope in accordance with OSHA regulations. In addition, vehicle traffic should be maintained at least 5 feet from the edge of the slope crest. Open-cut slope excavations should take into account any existing utilities in order to avoid undermining pipelines. The following guidelines are presented to aid in the development of the excavation plans: 1. Surface areas behind the crest of the excavations should be graded so that surface water does not pond within 15 feet of the crest, nor drain into the excavation. 2. Heavy material stockpiles should not be placed near the crest of slopes per OSHA requirements. Similarly, heavy construction equipment should not pass over or be parked within 10 feet of the crest. 3. The crest of slopes should be continually monitored for evidence of movement or potential problems. Freestanding slopes will become less stable when influenced by groundwater or saturation by rain. rr 4.3 Trench Bracing Where site limitations require excavations to have vertical sidewalls, an internal bracing system will be necessary. Bracing may consist of steel sheet piling, timber, or steel shoring or Page 5 of 19 sanitary sewer Main 442 Relief,Fort Wath.Texas TERRA-MAR, /NC. TMI No.FE02-169 _ February.2003 iqW� = Consulting—Geotechnical-Environmental - Construction Materials Testing manufactured steel trench braces. The trench bracing and bore pit shoring should be designed for a constant lateral earth pressure of'30nH', in psf; where, H is the excavation height in feet; n equals 1.3 for excavations in clays and sandy clays; and n equals 1.0 for excavations in clayey sands and sands. Surcharge loads and traffic live loads, if present, must be included in bracing design. In lieu of a shoring system, a trench shield consisting of a prefabricated rigid steel unit, adequate to withstand anticipated lateral pressures, may be used where lateral movements will not affect the stability of the existing pipelines. Trench excavation in the area of Boring B-1 and bore pits in the area of Borings B-7, B-8 and B-9 will extend into loose to dense sands. Sand could also be present in other areas of the alignment. Vertical trench walls are not expected to have sufficient standup time to allow placement of trench boxes or shields where sands and clayey sands are present in the trench walls. For these conditions, the trench walls will need to be sloped or have a driven sheet piling system or some other type of shoring that maintains continuous shoring against the soil. Depending upon the conditions encountered during construction, it may also be necessary to dewater the sand deposit in order to control excavation wall and base stability. 4.4 Jack Allowable Bearing Pressure Surficial clays and sandy clays encountered along the alignment are generally stiff to hard in consistency exhibiting unconfined compressive strengths of about 1 to 2.5 tsf with some harder zones. An allowable bearing pressure of 2,000 psf may be used for jack supports if the supporting soils are dry and relatively undisturbed. The bearing value includes a safety factor of 2, and assumes that jack supports are at least 8 feet below adjacent grade. Clayey sands and sands could be encountered at jacking locations. These materials will not provide comparable bearing pressures unless they are confined_ Page 6 of 19 Sanitary Sewer Main 442 Relief;Fort Worth.Texas TERRA-MAR, /NC. TMI No.FE02-169 February,2003 Consulting—Geotechnical-Environmental — Construction Materials Testing 4.5 Trench/Bore Pit Dewatering Based on the groundwater observations it is expected that groundwater seepage will occur in a majority of the excavations. Controlling groundwater is essential to construction of the pipeline. Failure to control the groundwater level could result in trench wall collapse, trench bottom heave, an unstable trench bottom and detrimental pipeline settlement and pipe deflections after backfilling. Groundwater levels should be maintained at least two feet below the bases of the excavation for the full term of construction. Protection of the open excavations should be provided during periods of moderate to heavy rainfall, as surface water will most likely channel and collect in the excavations. The water level should be lowered prior to excavating and should be maintained at this lowered level until the pipe trench is backfilled. It is likely that seepage in the clays may be controlled by means of collection ditches, sumps, and pumping. However, in the event that water infiltration rates are high, it may be necessary to install a more elaborate dewatering system. In some areas, water-bearing sand layers may be encountered during construction. A system of wells or well points will likely be required where water-bearing sands are present in the trench excavation in order to maintain the trench wall and bottom stability. Dewatering methods should consider the difficulty associated with the relatively low permeability of the clayey sands present at some locations. Dewatering of the sands is not necessary for sheet pile walls, provided the walls are designed for both earth and water pressures. Seepage from sheet pile joints should be anticipated. This seepage water should be collected and removed from the excavation. The Contractor should verify the presence and depth to groundwater prior to construction in order to determine dewatering requirements. The design of the actual dewatering system required is the contractor's responsibility. The groundwater control system should provide continuous system operation at all times. This includes the control of tailwater flow through the backfilled sections of ` previous utility construction. 4.6 Soft Trench Bottom Conditions Soft trench bottom conditions may be encountered. Unstable trench bottoms are considered to be unsuitable for support of the pipe. Sands, clayey sands and soft clays could be present that when exposed become unstable due to construction activity, improperly dewatering water bearing Page 7 of 19 Sanitary Sewer Main 442 Relief;Fat Worth.Texas TERRA-MAR, INC. TMI No.FE02-169 __ _ February,2003 ==-= consulting—Geotechnical-Environmental - construction Materials Testing sands or the presence of saturated low PI sandy clays or clayey sands that cannot be effectively dewatered. In any areas where unsuitable bearing deposits are encountered at the planned invert elevation the trench bottom can be prepared using one of the following methods: 1. Under cut to a suitable bearing subgrade and replace with a.structural compacted fill. The over excavation should extend laterally a distance of at least 1 foot beyond the edges of the pipe, and then at least 1 foot laterally for every 1.5 feet of fill required beneath the pipe. The overexcavation backfill should be completely surrounded With a geotextile consisting of Mirafi ° 140NL, Amoco 4545, or equivalent. The backfill should consist of a free draining aggregate (i.e. sands, gravels, crushed limestone, or crushed concrete) approved by the geotechnical engineer. The backfill should be placed in maximum 9-inch loose lifts and uniformly compacted to a minimum relative density of 65 percent as determined by test methods ASTM 4253 and 4254. _ 2. Casting a 6-inch thick reinforced concrete slab. The concrete should have a minimum 3,000 psi compressive strength at 28 days. Exposed shale in the bottom of the pipe trench or bore pit can deteriorate rapidly. Should the surface of the shale breakdown to a soft consistency prior to placing the pipe embedment material, the softened shale should be undercut and replaced with a thicker bedding layer. 4.7 Excavation Considerations If open trench cuts are performed within 1.25 times the trench depth of any surface structure, trench shoring (not trench boxes) should be used within open trench cuts performed within this distance. Hydraulic shoring struts should be used and installed during excavation as needed to provide full lateral support to vertical trench sidewalls and thereby, help reduce lateral ground movements near existing structures. A pre-construction condition survey should be performed prior to beginning excavation near any structure that could be affected by the trench excavation to verify existing conditions (existing distress) prior to construction. Construction monitoring should be performed to verify that existing structures are not impacted or damaged by construction operations. Conventional earth moving equipment is expected to be suitable for excavating the overburden soils and most shales. However, heavy-duty excavation equipment consisting of hoe-rams or backhoes with buckets with rock teeth may be required to excavate harder shale layers. While not encountered in the borings lightly to highly cemented sands and extremely hard sandstones .. can be encountered along the alignment. This material will require heavy-duty excavation equipment to excavate. Page 8 of 19 Sanitary Sewer Main 442 Relief;Fort Worth,Texas TERRA-MAR, //VC. TMI No,FE02-169 February,2003 Consulting—Geotechnical-Environmental Construction Materials Testing 4.8 Trench Backfill Pipe embedment should be a coarse-grained cohesion-less material that will properly fill the area below the spring line of the pipe. This bedding should extend above the pipe a minimum of 6 inches to provide protection of the pipe during placement of the trench backfill. Site excavated materials are generally considered suitable for use as backfill above the pipe bedding materials. All trench backfill should be free of deleterious materials. However, significant processing of shales or cemented sands and sandstones (if encountered) will be required to use this material as fill. Excavated rock used as fill should be pulverized to a maximum size of 6 inches with at least 50 percent passing a No. 4 sieve. Use of rock fragments greater than 6 W. inches in any dimension should be prohibited, since attaining a uniform moisture and density without voids would be difficult. Shale and rock fragments larger than 6 inches in diameter should - be crushed by tracking over the material with a dozer. It may be necessary to remove larger hard rock fragments that will not crush under the loads of the construction equipment. Backfill should be compacted in maximum 9 inch loose lifts at a minimum of 95% of the Standard Proctor density (ASTM D698). Shale should not be used for backfill if large settlements are a concern. The shale will weather in place to a soil. This weathering can result in larger ground subsidence as discussed in the next report section. Clay soils having a PI over 20 should be compacted at a moisture content ranging from 0 to + 4 percent above the optimum moisture content. Granular soils having a PI less than 20 should be �. compacted at a moisture content ranging from —3 to +3 percent of the optimum moisture content. Jetting to compact the pipe backfill should not be allowed. In areas where settlement of the backfill must be closely controlled, the trench excavation should be backfilled with either cement stabilized sand or consideration can also be given to fiowable concrete having a 28-day - compressive strength ranging between 50 and 200 psi as an alternative. 4.9 Trench Backfill Settlement Settlement of the backfill soils should be anticipated. It is anticipated that properly compacted on- site clay fill soils will settle between about 1 and 2 percent of the fill thickness. For example, 25 feet of fill would be expected to settle on the order of 3 to 6 inches. A greater amount of fill settlement could occur if shale fragments are used as fill due to the breakdown of the shale Page 9 of 19 Sanitary Sewer Main 442 Reef;Fort Worth,Texas TERRA-MAR, /NC. CMI No.FE02-169 February,2003 Consulting—Geotechnical-Environmental Construction Materials Testing fragments into individual clay-size particles over time. These settlements could approach 3 to 5 percent of the fill thickness depending on the thickness of shale placed as backfill. The trench backfill could be overbuilt in order to reduce the potential for a surface depression along the trench centerline. We recommend the backfill be crowned. The centerline of the excavation should be over built one foot and sloped down to match grade at the edge of the excavation. 4.10 Provisions to Reduce Backfill Settlement Field testing :will be a critical element in controlling the compaction of the backfill to limit settlement. All trench backfilling in these critical areas shall include full-time observation of soil compaction by an experienced geotechnician under the supervision of the geotechnical engineer. The contractor should provide protection for the testingfinspection personnel while working in the trenches, and shall move the protective shield/shoring such that areas to be tested are readily accessible. The compacted moistureldensity of all backfill soils should be tested at a rate of one test per 100 linear feet of trench, for each lift of fill placed, during construction. Digging through existing lifts of backfill to access and test underlying lifts should not be allowed. In addition, to limit settlement, where Class 1 and Class 2 crushed stone materials are used as pipe bedding materials, they should be wrapped with a suitable geotextile to limit the intrusion of fines into the crushed stone material. 4.11 BorelTunnel Considerations The sanitary sewer line has 6 bores which total approximately 5,100 feet. The approximate bore .� depths, bore length and anticipated soil conditions at the representative boring location(s) is summarized in the following Table 2.

The 700 foot bore will encounter clay at the invert elevation in the vicinity of Boring B-4 changing from clay to shale at the invert elevation between Boring B-4 and B-5, to the south with significant water seepage in Boring B-5. The strata at the invert elevation for the 3289 foot bore varies from shale in the vicinity of Borings B-6 and B-8; shaley clays in the vicinity of Boring B-7; and clayey sands in the vicinity of Boring B-9. Seepage was present in the sandy clays in Boring B-8 and in the sands in Borings B-7 and B-9. Boring and tunneling in the clayey sands and sands will be difficult because the clayey sands and sands are not expected to have sufficient standup time to allow open face excavations. In addition, tunnel roof stability and floor stability problems may develop in boring and tunneling in the sands. Dewatering prior to boring/tunneling operations and/or special boring/tunneling techniques will be required to control excavation instability associated with the clayey sands and sands to prevent ground loss and subsequent settlement of structures overlying the tunnel. Joints present in the shale can result in separation with rock falls into bore/tunnel excavations. Groundwater could seep into bore/tunnel excavations. Joints in the shale and shaley clays can serve as conduits to direct water towards the bore excavation. Water seepage can decrease the stability of the bore/tunnel excavation and result in ground subsidence. The shales and highly active clays are expansive and will swell when water is available to them subjecting the pipe to uplift pressures. The'swell pressures will reduce as the material swells.

TMI No.FE02-169 February,2003 =-__— Consulting—Geotechnical-Environmental Construction Materials Testing 5.0 PIPE DESIGN RECOMMENDATIONS 5.9 Flexible Pipe Deflection The modified Iowa formula is typically used to estimate vertical deflection of flexible pipe. One form of the modified Iowa formula is given below: AY__ 0 L x WS +WL)<K X o — x100% D 0.149xPS +0.061xEd Where: oy/D = predicted vertical pipe deflection as a percent of the outside pipe diameter. Ay = change in vertical diameter of pipe, inches. D = diameter of pipe, inches WS = vertical soil load on pipe, psi. WL = live load on pipe from trucks or construction equipment, psi. DL = deflection lag factor to adjust for changes in bedding stiffness or trench fill settlement, dimensionless. KX = bedding coefficient, dimensionless. Ed = design modulus of soil reaction, psi. PS = pipe stiffness, Ib/in./in., psi. The modified Iowa formula models the major factors influencing pipe-soil interaction resulting from soil and live loads acting on the pipe and support provided by the bedding material surrounding the pipe. Pipe deflections due to self-weight and due to placement and compaction of backfill are not addressed by the modified Iowa formula. The actual deflections may vary from the deflections calculated using the modified Iowa formula due to variations soil loads, live loads, embedment materials, methods of construction, and the inherent variability of subsurface conditions along the pipeline alignment. Reasonable predictions of pipe deflections can be made using the modified Iowa formula if pipe bedding and backfill materials are properly placed and compacted using good construction practices and appropriate equipment.

February,2003 __=- Consulting-Geotechnical-Environmental Construction Materials Testing w� 5.2 Vertical Soil Loads We recommend that the long-term vertical soil pressure, W.i acting on the top of flexible pipe be taken as the soil unit weight times the depth of cover above the pipe. The soil pressure can be computed from the following relationship: YsxH _ 125xH _ Ws . 144 144 'PSI Where: WS = vertical soil pressure, psi 75 = unit weight of soil above top of pipe, pcf. A soil unit weight of 125 pcf is recommended for design H = depth from ground surface to top of pipe, feet. Cautionary Note: The vertical soil pressures computed using the above equation should not be used to estimate the sliding frictional resistance for the design of restrained pressure pipe joints for pipes installed in trenches. The vertical soil pressure may be less than computed by the above equation when the pipe is pressure tested. The vertical soil pressures may be less - because of soil arching on the sidewall of the trench will prevent the full overburden pressure from acting on the force main pipe. The vertical loads acting on a rigid pipe can be computed using Marston's equations for computing the estimated soil loads on rigid pipe installed in trenches or in embankment conditions. A soil unit weight of 125 pcf is recommended for design. If the trench will be backfilled primarily with shaley clays and/or shale, we recommend that the vertical earth load be based on the full weight of the soil above the pipe. This recommendation is made because the shaley clays and shales placed as trench back fill will deteriorate and soften. This softening will result in large backfill settlements and that could result in complete or partial loss of soil arching effects. For this reason, shaley clay or shale arching should not be relied upon for computing soil loads on rigid pipe. salt Of R1,1HARY Page 13 of 19 OR°H! 0.

TMI No.FEO2-169 February,2003 —__ Consulting–Geotechnical-Environmental Construction Materials Testing 5.3 Live Loads Live loads, WL, from trucks and construction equipment should be included in the pipe deflection calculations. Live loads from trucks do not need to be included where the top of the pipe is 8 or more feet below finished grade. ,® Impact loads from trucks should be included where the top of the pipe is less than 3 feet below the truck tire. An impact factor of 1.35 is recommended for depths less than or equal to two feet and an impact factor of 1.15 is recommended for depths between two and three feet. The impact factor should be applied to the wheel load. 5.4 Deflection Lag Factor The deflection lag factor, DL, is a coefficient to correct for long term deflection of the pipe. A deflection lag factor of 1 is recommended if the vertical soil pressure is computed as recommended in Section 5.2 and the pipe is constructed above the water table. A deflection lag factor of 1.5 is recommended where groundwater will rise above granular pipe embedment in the pipe zone for pipe embedment backfill placed at less than 70 percent relative density. A deflection lag factor of 1.0 is recommended for Class 3 Pipe Embedment Backfill. 5.5 Bedding Coefficient The bedding coefficient, Kx, is a factor that takes into account the degree of support the bedding +� material provides under the pipe. A bedding coefficient of 0.1 is recommended for use for granular bedding layers. A bedding coefficient of 0.083 is recommended for use with Plowable �. backfill. 5.6 Modulus of Soil Reaction The modulus of soil reaction, Ed, is a measure of the lateral stiffness of the pipe zone backfill material and the native soil in the sidewall of the trench resisting horizontal movement of the pipe. The moduli of soil reaction are dependent`on the material type and amount of compaction in the e, native soil characteristics, trench width, and cover depth. The design modulus, Ed, can A� ., uted from the following relationship: E x S,, psi Pana 14 of 19 Sanitary Sewer Main 442 Relief;Fort worth.Texas TERRA-MAR, INC.

S, is a stiffness correction factor to account for trench soils with a lower stiffness than the pipe backfill materials. We recommend a stiffness correction factor of 1.0. 5.7 Corrosion Potential Various laboratory tests were performed to evaluate the soil corrosion potential to buried iron and metals including soil resistivity, pH, oxidation-reduction (redox) potential and sulfides determinations. The results of these tests are reported on Figure 26. The tests indicate that the subsurface soils are considered to be nearly non-corrosive to buried ductile iron or cast iron pipe. The tests also indicate the soils are nearly non-corrosive to buried concrete structures in the tested areas. Methodology outlined in the Handbook: Ductile Iron Pipe, Cast Iron Pipe, 51h Edition, published by the Cast Iron Pipe Research Association was used to evaluate the corrosivity of the subgrade -- soils with respect to buried pipe. The American Concrete Institute methodology was used to establish corrosion potential of buried concrete structures. A key to test results and point system - summary is given on Figures 27 and 28.

Sanitary Sewer Main 442 Relief;Fort Worth,Texas .� TERRA-MAR, INC. TMI No.FE02-169 i February,2003 —_g= Consulting—Geotechnical-Environmental Construction Materials Testing 6.0 MANHOLE & JUNCTION BOX DESIGN RECOMMENDATIONS 6.1 Allowable Bearing Pressure The proposed manholes and junction boxes will be supported in clays, shale and occasionally sands and clayey sands. These structure foundations can be designed using a maximum net allowable bearing pressure of 2,000 psf. This allowable bearing pressure includes a factor of safety of at least 3. It is expected that the total settlement will not exceed 1 inch where the bearing materials are undisturbed. At least half of the settlement is expected to occur as the manholes are constructed. .� Clays and shales at the bottom of the structure can soften when exposed to water. In addition, sands and clayey sands and clays, if near the zone of seepage, are subject to bottom instability .. where influenced by groundwater. The bearing surface of the structure foundation should be protected as previously described in Section 4.6. 6.2 Manhole and Junction Box Backfill .� The manhole and junction box excavations along the cut and cover sections of the alignment can be backfilled with on-site soils. The manhole and junction box excavations along the bore/tunneled sections of the line are recommended to be backfilled with flowable fill or cement- treated sand. On-site clays are not recommended for use as backfill along the bored/tunneled sections of the line since excessive settlement of these soils is expected. 6.3 Lateral Earth Pressures The manhole and junction box walls will be restrained from movement and should therefore be designed for an at-rest earth pressure condition. We understand the ground elevations for all structures are below the 100-year flood level except for structures near Borings 8-6, B-7 and B-8 which are about 1 to 2.5 feet above the 100-year flood level. Therefore, undrained conditions are assumed for all structures. Recommended equivalent fluid pressures for a level ground surface. and undrained walls are presented below in Table 4. The undrained conditions include hydrostatic pressures. The equivalent fluid pressures for the flowable backfill are applicable only after the fill has set-up. Immediately following fill placement, when the fill is in a plastic state, it is expected to have an Page 17 of 19 Sanitary Sewer Main 442 Relief.Fort Worth,Texas TERRA-MAR, /NC. TMI No.FE02-169 _ February,2003 z= Consulting—Geotechnical-Environmental Construction Materials Testing equivalent fluid pressure of about 150 pcf. If the fill is to be placed in a single pour, the walls should be designed to resist the lateral pressures induced by the full column of fill. As an altemate, the fill could be placed in several lifts, allowing each lift to harden prior to the placement of the next lift. The plans should specify the allowable lift thickness so that the lateral pressures induced by the fill do not exceed the design lateral pressures. TABLE 4— RECOMMENDED EQUIVALENT FLUID PRESSURE Type of Backfill Equivalent Fluid Pressure (pcf) Flowable Fill 70 pcf Cement Treated Sand 80 pcf - Site Clays 114 pcf Surcharge loads should be included in the wall design. A lateral earth pressure coefficient of 0.5 is recommended for design if site clays are used. Surcharge loads do not need to be included if flowable fill is used. 6.4 Wall Backfill The flowable fill should have a 28-day compressive strength ranging between 50 and 200 psi. i The on-site shale is not recommended for use as fill due to the potential for large backfill settlement caused by.a softening of the shale and increased lateral wall loads with time. The site clays should be placed in maximum 8-inch lifts and uniformly compacted to at least 95 percent of the Standard Proctor density (ASTM D 698) for cohesive soils. The moisture content for cohesive soils should be within 2 to 5 percentage points above the optimum moisture content (ASTM D-698). Heavy compaction equipment should not be used directly against the walls. Hand operated equipment should be used within 4 feet of the walls. The backfill should be brought up in a relatively uniform rate to avoid differential fill heights of greater than two feet.

'- TMI No.FE02-169 February,2003 —_- Consulting-Geotechnical-Environmental Construction Materials Testing 6.5 Backfill Settlement It is estimated that settlement of the flowable fill or cement stabilized sand is expected to be less than about 1 inch. Site clay is expected to settle on the order of up to 2 percent of the total height of the fill. 7.0 INSPECTION AND TESTING Many problems can be avoided or solved in the field if proper inspection and testing services are provided. It is recommended that all field operations related to soil placement and compaction be ®► monitored by a qualified engineering technician. Field density and moisture content determinations should be made on each lift of fill with a minimum of 1 test per lift per 200 linear feet of trench backfill.

TMI No.FE02-169 _ February,2003 —__ _ Consu"—Geotechnical-Environmental Construction Materials Testing APPENDIX - STANDARD FIELD AND LABORATORY INVESTIGATION PROCEDURES ^� FIELD INVESTIGATION PROCEDURES The borings for this investigation were staked in the field by a Terra-Mar engineer using simple } taping procedures from reference points noted on the site plan provided by the client. A field log of each boring was recorded during field drilling operations. These field logs and soil �. classifications were reviewed/verified by a geotechnical engineer in the laboratory through visual classification. Samples were visually classified according to color, texture, predominant material type, consistency and density. Results from the laboratory testing.program along with the visual classification of each soil stratum were used in the determination of the USCS classification for each soil stratum (ASTM D-2487). Finalized boring logs are provided in the report, as noted in the table of contents. Please note that the lines of soil demarcation represent the approximate soil boundary between differing material types, and that the actual transition between the soil strata in the field may be gradual. Truck mounted drilling equipment was used to advance the borings to the completion depths using solid stem auger procedures. Soil samples were foil wrapped and sealed in plastic bags, for moisture control, and were marked to identify the boring number, sample depth, and job number. Unless notified to the contrary, soil/rock samples/cores will be stored for 90 days, and then discarded. Field soil/rock sampling procedures were performed in accordance with the following standards: Thin Walled "Shelby" Tube Sampling (ASTM D-1587) This sampling method consists of pushing thin walled steel tubes, with an approximate 3 inch outside diameter, into the soil to be sampled using pressure provided hydraulically by the drilling .r rig, or manually by the field technicians. This sampling method is typically used on cohesive soil samples, and produces samples that are relatively undisturbed and suitable for shear strength testing, consolidation testing, permeability testing, and in-situ density approximation. TxDOT Cone Penetrometer Test "THD" (TEX-132E) The THD Cone Penetrometer Test is a field test established by the Texas Department of Transportation to determine the relative density and load carrying capacity of deep foundation materials (typically rock formations). In this test, a 3 inch diameter penetrometer cone is seated into the strata to be sampled. The cone is then driven into the strata using a 170 pound weight freely falling over a distance of 24 inches. The cone is driven until either the blow count reaches 50, or the penetrometer has been driven 6 inches. The number of blows and the distance driven is then recorded on the field logs. The results of the field test are then used in a table that correlates the load carrying capacity and skin friction of the proposed bearing strata to the field test results. Sampling by Auger Boring Method "Grab Sample" (ASTM D-1452) This sampling method consists of sampling the soil samples by removing representative soil samples from the continuous flight augers used to drill the boring, or by removing soil samples + + from the cuttings brought to the surface by the augers. This method provides highly disturbed samples that are appropriate for classification purposes only. .r Sanitary Sewer Main 442 Relief.Fort Worth.Texas TERRA-MAR, IMC. TMI No.FE02-169 February,2003 —_ -- Consulting—Geotechnical-Environmental Construction Materials Testing Standard Penetration Test (SPT) and Split Barrel Sampling of Soils (ASTM D-1586) This sampling method consists of driving a 2-inch outside diameter split barrel sampler into the soil strata using a 140 pound hammer freely falling through a distance of 30 inches. The sampler is first seated 6 inches into the soil to be sampled, and is then driven an additional 12 inches in 6 inch increments. The number of blows required to drive the sampler the final 12 inches is then known as the Standard Penetration Resistance. The results of the SPT tests are given in blow counts per 6 inches on the boring logs. This sampling method is typically used for sampling non- cohesive or low cohesion soils, and gives an indication of the relative density of the in-situ soils, which can then be used to estimate allowable bearing capacities and potential elastic settlement Within the soil mass. Diamond or Carbide Core Drilling for Site Investigation (ASTM D-2113) This sampling method consists of sampling very hard strata (typically rock formations) by advancing a rotating double tube core barrel equipped with a diamond or carbide cutting bit. During this procedure, wash water or highly compressed air is used to remove excess material cuttings, and to cool the cutting bit. Typically, a 3 inch outside diameter by 2-1/8 inch inside diameter coring bit is used, unless otherwise noted. The recovered material is then examined in ®' the field and stored according to the procedures mentioned at the beginning of this section. The soundness of the recovered cores were evaluated in two ways. These included calculating the Recovery Ratio (REC) and the Rock Quality Designation (RQD). These values are calculated according to the following formulas: REC = (Total Length of Core Recovered / Length of Core Run) x 100 RQD = (Total Length of Cores Rec. Greater than 4 inches/ Length of Core Run) x 100 Higher REC and RQD values are an indication of the cored material quality and its suitability as a bearing material. Generally speaking, the closer the REC and RQD values are to 100%, the higher the quality of the cored material. These values are recording on the boring logs next to the sample run when appropriate. Please note that RQD values can sometimes be rather low due to the presence of hard layers in the rock strata and/or mechanical breakage in the coring tube. In these instances, the REC and RQD values are not recorded on the boring logs. Groundwater Observations Groundwater observations were made during drilling operations, and after a period of at least 24 hours, unless otherwise noted on the boring logs. It should be noted that the use of water during coring operations can make the determination of groundwater conditions difficult. When necessary, wash water was bailed out of the borehole to a depth below the depth of seepage observed during drilling operations. LABORATORY INVESTIGATION PROCEDURES Sanitary Sewer Main 442 Relief;Fort Worth.Texas TERRA-MAR, INC. TMI No.FE02-169 _ February,2003 Consulting—Geotechnical-Environmental Construction Materials Testing The laboratory-testing program was directed primarily toward the evaluation of the physical and engineering characteristics of the underlying site soils. A Geotechnical Engineer performed �• identification tests, unless otherwise noted. The results of this laboratory-testing program are shown at the appropriate sample depths on the boring logs, or on the appropriate figures. Unless otherwise noted, laboratory procedures were performed according to the following procedures: Moisture Content (ASTM D-2216) Natural moisture contents of the soil samples (based on the dry weight of the soil) were .� determined for selected samples at selected depths. These moisture contents are useful in delineating the depth of the zone of moisture change with an increase in subsurface depth, and can be useful in locating the groundwater table. The moisture content can also be useful in analyzing and evaluating the expansion potential and/or shear strength of soil samples. The results of the test(s) are reported at the appropriate depth(s) on the boring log(s). Atterberg Limits "Liquid and Plastic Limits" (ASTM D-4318) The Atterberg Limits are given as the particular moisture contents of fine grained soil materials when they meet the requirements of a predefined test. In particular, the Plastic Limit (PL) is given as the approximate moisture content at which the soil material begins to behave more like a plastic material than a semi-solid material. Similarly, the Liquid Limit (LL) is given as the moisture content at which the soil material begins to behave more like a liquid material than a plastic *• material. The difference of these two test values can then be calculated, and is known as the Plasticity Index (PI). Larger PI values indicate an increased ability of the soil material to remain in a plastic state with changes in the moisture content. The results of the test(s) are reported at the An appropriate depth(s) on the boring log(s). The Atterberg Limits can then be used in conjunction with other parameters to classify the soil according to the Unified Soil Classification System (USCS). These parameters are also useful in evaluating the expansion potential of the fine grained soil materials with fluctuations in the moisture content. Unconfined Compressive Strength of Soil Samples (ASTM D-2166) The unconfined compressive strength testing of the soil sample(s) was performed in order to evaluate the undrained shear strength of the soil material(s). For this test, a sample with a minimum length to diameter ratio of 2:1 was used whenever possible in order to reduce end +I• effects during testing. If the ratio was less than 2, a correction was applied according to standards listed in the ASTM manual. The results of the unconfined compressive strength test is useful in evaluating the shear strength of soil materials in undrained conditions and can also be used to determine the amounts of cohesion present. The results of the test(s) are reported at the appropriate depth(s) on the boring log(s). Unconfined Compressive Strength of Rock Cores (ASTM D-2938) The unconfined compressive strength of the rock material(s) was determined in order to evaluate the soundness of the rock material, and give a general indication of the ultimate bearing capacity of the bearing formation. For this test, the sample(s), with a minimum length to diameter ratio of Sanitary Sewer Main 442 Relief.Fort worth,Texas TERRA-MAR, MC. TMI No.FE02-169 February,2003 =_ _ Consulting-Geotechnical-Environmental -! construction Materials Testing 2:1, was used whenever possible in order to reduce end effects during testing. If the ratio was less than 2, a correction was applied according to standards listed in the ASTM manual. The results of the test(s) are reported at the appropriate depth(s) on the boring log(s). Pocket Penetrometer Shear Strength Evaluation A small hand held penetrometer device was used in the laboratory to evaluate the shear strength of relatively undisturbed cohesive soil samples. In this test, the flat tip of the device is placed on a flat portion of the undisturbed sample. A constant pressure is then applied until the device penetrates the sample a predetermined amount. The approximate shear strength developed is then read on the side of the device in tons per square foot, and is reported at the appropriate depth on the boring log(s). This test is valuable in developing relative correlations of the consistency of soils across the site, and can also be used as an indication of the in-situ moisture content relative to other samples. Percentage Passing the Number 200 Sieve (ASTM D-1140) The amount of material passing a Standard Number 200 sieve was determined by wet washing the material over a number 200 sieve nested with a number 8 sieve (to protect the No. 200 mesh). The results of the test(s) are useful in the classification of the soil material, and are shown at the appropriate depth(s) on the boring log(s). Grain Size Analysis (ASTM D-422) Grain size analysis tests were performed on selected samples to determine the particle size and distribution of selected soil samples. The distribution of the soils coarser than the Standard Number 200 Sieve were determined by washing and dry sieving the soil materials over a set of nested wire cloth sieves. When necessary, the distribution of the soil materials finer than a Standard Number 200 sieve were determined using a hydrometer sedimentation process. The results of the test(s) are given on the Grain Size Distribution Report as noted in the Table of Contents.
