The project consists of street improvements of Merrick and Bourine Streets including the replacement of the existing water lines, sewer lines, and storm drains(see Plans). Trenches for the water line will be approximately 2 feet wide and 5 feet deep. Trenches for the sewer line and storm drain are called out on the plans. Erosion control measures in the form of hay bales, silt fences,filter dikes, and inlet protectors will be used during construction to minimize storm water pollution resulting from the construction. Erosion control measures will be available on-site prior to construction. The contractor will use work practices described in this Storm Water Pollution Prevention Plan (SWPPP) to minimize the introduction of sediment to the extent possible without violating the conditions set forth in the contract documents. b. Notice of Intent All parties defined as owners or operators must submit a Notice of Intent(NOI)at least 2 days prior to commencement of on site construction activities. Submittal of late NOI's is not prohibited,however, authorization under the construction general permit is only for discharges that occur after permit coverage is granted. Unpermitted discharges may be subject to enforcement actions by the EPA. For the purpose of this permit,an operator is defined as any party meeting either of the following requirements: 1. The party has operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications. 2. The party has day-to-day operational control of those activities at a project,which are necessary to ensure compliance with a storm water pollution prevention plan for the site or other permit conditions. Copies of all NOI's associated with this project are included in Attachment 1 of this SWPPP.A copy of the NOI must be posted at the construction site in a location where it is readily available for viewing prior to construction activities. The notice shall remain in the location until construction activities have been completed. C. Operator Compliance Certification and Authorized Signatory This SWPPP must be compliance certified by the appropriate authorized representative of the City of Fort Worth on the Operator Compliance Certification sheet and Authorized Signatory sheet located in Attachment 2. d. Certification Sheets All contractors, subcontractors and operators engaged in activities under this SWPPP that ' disturb surface soil must be identified and must sign a certification statement located in Attachment 3. r e. Sequence of Major Activities It is desired that the Contractor apply generally accepted erosion control, sediment loss prevention, and waste management practices as described in the North Central Texas Council of Governments'Storm Water Quality Best Management Practices for Construction Activities. At a minimum,the Contractor will use a combination of silt fences and straw bale dikes to control sediment loss and geotextile mats for erosion control (See Attachment 4). 1. Place sediment control structures at downstream inlets, including all culverts under the roadway, prior to beginning the clearing of trees and other vegetation from the portion of the project in inlet's drainage area. The erosion control measures are shown in this SWPPP. 2. Provide a silt fence around all areas used to store fill materials. 3. Provide stabilized construction entrance(See Attachment 5)for any equipment staging areas. 4. The Contractor shall provide sediment control methods along the area of active construction. 5. The disturbed areas shall be covered with permanent stabilizing material within 14 calendar days of closing trenches for water lines, sewer lines, or storm drains,and when the reconstruction of the roadway is complete. Once the permanent stabilizing material is in place,the active construction erosion control devices shall be removed. 6. Water newly seeded areas with an amount of water and at a frequency needed to establish ground cover. Do not remove sediment controls structures at inlets until ground cover has been reestablished. 7. Inspect sediment and erosion controls after each rainfall and modify controls as needed to correct deficiencies. f. Estimated Total Site Area Disturbed Area Approximately 3.8 acres of the site will be disturbed at one time or another during the project. Natural vegetation, including trees, shrubs, grasses,and weeds will be disturbed during the construction activities. g. Ground Cover The ground cover that will be disturbed consists of natural vegetation including grasses, weeds, shrubs, and some trees. h. Runoff Coefficient The runoff coefficient "c" for the paved areas that will be disturbed is 0.9. The runoff coefficient for the vegetated areas will vary from 0.2 to 0.3. The estimated runoff coefficient for the overall project is 0.80. Completion of this project is not expected to alter the above runoff coefficients. i. Site Map A USGS topographic map is attached(Attachment 6). j. Soil Type,Topography,and Climate The soil map, soil types, and descriptions for the soils are shown in Attachment 7. k. Name of the Receiving Water and Extent of Wetlands Lake Como,which is owned by the City of Fort Worth. I. Location and description of any discharge associated with industrial activity other than construction: None. M. Endangered and Threatened Species. The habitat for endangered species within Tarrant County will not be disturbed for this project. n. National Register of Historic Places. The areas that will be disturbed by the proposed project are not listed in the National Register of Historic Places. o. Notice of Termination Compliance of the site with the General Construction Permit remains the responsibility of all operators that have submitted an NOI until such time as they have submitted a Notice of Termination(NOT). The permittee's authorization to discharge under the General ' Construction Permit terminates at midnight of the day the NOT is signed. All permittees must submit an NOT within thirty(30)days after one or more of the following conditions have been met: I. Final stabilization has been achieved for all portions of the site for which the permittee was responsible. 2. Another operator/permittee has assumed control over all areas of the site that have not been finally submitted. 3. In residential construction operations,temporary stabilization has been completed and the residence has been transferred to the homeowner. A copy of the NOT associated with this construction operation is included in Attachment 8. P. TCEQ Permit Requirements A copy of the Texas Commission on Environmental Quality TPDES General Permit to discharge waste for construction sites is provided in Attachment 9. 2.0 Controls All controls described herein will be constructed in accordance with the North Central Texas Council of Governments'Storm Water Quality Best Management Practices for Construction Activities for the referenced project. Construction details are provided in Appendix A and Attachment 4. a. Performance Standards In keeping in compliance with Part IV.D.2.a of the EPA's General Construction Permit the following short and long term goals and criteria need to be applied.It is EPA's intent that erosion and sediment controls should be designed to retain sediment on site to the extent practicable. All control measures must be properly selected, installed, and maintained in accordance with the manufacturer's specifications and good engineering practices. If periodic inspections or other information indicates a control has been used inappropriately, or incorrectly,the permittee must replace or modify the control for site conditions. If sediment escapes the construction site, off-site accumulations of sediment must be removed at a frequency sufficient to minimize off-site impacts(e.g., fugitive sediment in street could be washed into storm sewers by the next rain and/or pose a safety hazard to users of public streets). b. Erosion and Sediment Controls Major erosion and sediment controls will be installed as shown on the plans prior to the start of construction as outlined under this SWPPP and will be maintained by the Contractors or his Subcontractors. 1. Nonstructural Practices i. Upon the installation of the water lines, sewer lines, or storm drains, and the street improvements have been performed, a seeded erosion control y mat will be provided for disturbed areas by the contractor. ii. When all construction activity is completed and the site is stabilized, temporary structural control devices will be removed and soils disturbed by their removal will be reseeded. Stabilization occurs when 70%of the vegetation is growing in disturbed areas. The General Permit provides that stabilization measures must be initiated on portions of disturbed areas where construction activities have temporarily or permanently ceased as soon as practicable, but no more than 14 days after construction activity on that particular portion of the site has temporarily or permanently ceased unless construction activities will resume on that portion of the site within 21 days from the date that construction activities ceased. } 2. Structural Practices i. Sediment control devices such as a silt fence will be placed in drainage ways to trap any sediment generated from construction. These will be removed upon stabilization of the site. ii. Haybales, burlap bag barriers, inlet control devices,triangular sediment filter dikes will be placed on either side of existing and proposed inlets to trap sediment that escapes silt fences. The erosion control measures will be removed after final stabilization of the site. C. Storm Water Management Storm water from adjacent properties will be discharged by overland flow to the proposed or existing storm drain system,then into the natural drainage system. d. Other Controls 1. Waste Disposal i. Waste Materials All trash and construction debris from the site will be disposed of off-site by the Contractor. The trash and debris will be hauled to an approved landfill. No construction waste material will be buried onsite.All personnel will be instructed regarding the correct procedure for waste disposal. The Contractor's foreman,who manages the day-to-day site operations,will be responsible for seeing that these procedures are followed. ii. Hazardous Waste No hazardous waste is expected to be generated or encountered in this project. In the event that hazardous waste is encountered, all hazardous waste materials will be disposed of in the manner specified by local or state regulation or by the manufacturer. The Contractor's foreman,who manages day-to-day site operations,will be responsible for seeing that these practices are followed. iii. Sanitary Waste All sanitary waste will be regularly collected from the portable units provided by a licensed sanitary waste management contractor. 2. Dust Control The contractor will use appropriate measures to control dust. - 3. Demonstration of Compliance with State and Local Regulations The proposed project will be in compliance with applicable state and local waste disposal and sanitary sewer regulations. e. Approved State or Local Plans There are no approved state or local site plan requirements for storm water management or erosion and sediment control. Guidelines presented in the North Central Texas Council of Governments'Storm Water Quality Best Management Practices for Construction Activities should be followed during construction. f. Off-Site Vehicle Tracking Normally,off-site vehicle tracking of sediments is not a problem at the site. However, as mentioned, a stabilized construction entrance should be provided,if needed,to help reduce vehicle tracking of sediments on paved roadways. Attachment 5 shows a typical stabilized construction entrance. Paved streets can be swept whenever it is necessary to remove excess mud,dirt, or rock tracked from the site. g. Petroleum Products All on-site vehicles will be monitored for leaks and will receive regular preventive maintenance to reduce the chance of leakage. Petroleum products will be stored in tightly sealed containers, which are clearly labeled. h. Paints and Sealers In instances where paints and sealers are needed, all containers will be tightly sealed a stored when not required for use. Excess paint will not be discharged to the storm sewer system but will be properly disposed of according to the manufacturer's instructions a state and local regulations. L Concrete Trucks Contractor shall provide a location for concrete trucks to wash out or discharge surplus concrete or drum wash water on the site. The concrete wash out location shall be enclosed with silt fence and shall have a slight depression to catch the concrete. When concrete has set,the waste concrete shall be disposed in an appropriate landfill. 3.0 Maintenance The following is a list of erosion and sediment controls to be used on this project. a. Stabilization Practices i b. Structural Practices I. Filter fabric fences. 2. Haybales on upstream side of existing headwalls. 3. Triangular Sediment Filter Dikes at intersections. 4. Inlet protection devices(shown in plans)at all existing or proposed inlets,during construction activities. 5. Any other method of reducing sediment deemed appropriate by the contractor. C. To maintain the practices described above,the following will be performed by Contractor 1. Maintenance and repairs will be conducted within 24 hours of inspection report (see Section 4.0 below). 2. Sediment will be removed from behind the sediment fences when it becomes about one-third the height of the fence. - 3. Sediment will be removed from the sediment trap when storage capacity has been 50%filled. 4. All temporary controls will be removed after the disturbed areas have been stabilized. 5. Paved streets adjacent to the construction staging entrance will be cleaned z regularly to remove excess mud and dirt tracked from the site. d. Seeded areas will be inspected to confirm that a healthy stand of vegetation is maintained. The site has achieved final stabilization once all areas are covered with pavement, or have a stand of vegetation with at least 70%of the background vegetation density. The density of 70%or greater must be maintained to be considered as stabilized. The operator or their representative will water, fertilize and reseed disturbed areas as needed to achieve this goal e. In the event that sediment escapes the construction site, off-site accumulations of sediment must be removed at a frequency sufficient to minimize adverse impacts. An example of this may be the situation where sediment has washed into the street and could be carried into the storm sewers by the next rainfall and/or pose a safety hazard to users of public streets. { f. Specific individuals will be responsible for inspections, maintenance and repair activities, and filling out the inspection and maintenance report. g. Personnel selected for inspection and maintenance responsibilities will receive training. They will be trained in the inspection and maintenance practices necessary for keeping the erosion and sediment controls in good working order. h. Based on inspection results, any necessary modification to this SWPPP shall be implemented within seven(7)calendar days of the inspection. A modification is necessary if a control measure or operational procedure does not provide adequate pollutant control. All revisions shall be recorded on the Record of Revisions(included in Attachment 10)within 7 calendar days of the inspection. Revisions must be shown on the job site copy. i. It is the responsibility of the operator to maintain effective pollutant discharge controls. Physical site conditions or contractor/subcontractor practices could make it necessary to install more controls than were originally planned. For example, localized concentrations of surface runoff or unusually steep areas could require additional silt barrier,or other structural controls. Assessing the need for, and installing additional controls will be a continuing contractor/subcontractor responsibility until final stabilization is achieved. Contractors and subcontractors implementing this SWPPP must remain alert to the need to periodically refine and update this SWPPP in order to accomplish the intended goals. 4.0 Inspections a. The Contractor will designate a qualified person or persons to perform the following inspections: 1. Disturbed areas and areas used for storage of materials that are exposed to precipitation will be inspected for evidence of, or the potential for,pollutants entering the drainage system. 2. Erosion and sediment control measures identified in the plan will be observed to assure that they are operating correctly. 3. Where discharge locations or points are accessible,they will be inspected to ascertain whether erosion control measures are effective in preventing significant Y impacts to receiving waters. 4. Locations where vehicles enter or exit the site will be inspected for evidence of offsite sediment tracking. The inspection will be conducted by the responsible person at least once every seven- calendar days and within 24 hours after a storm of 0.5 inches or greater. After a portion of the site is finally stabilized, inspection will be conducted at least once every month. b. Based on the results of the inspection,the site description (Section 1)and control measures(Section 2)of this Pollution Prevention Plan will be revised as appropriate, but in no case later than seven calendar days following the inspection. C. A report summarizing the scope of the inspection,name(s)and qualifications of personnel making the inspection,the date(s)of the inspection, major observations relating to the implementation of the storm water pollution prevention plan, and actions taken in accordance with item "b" above will be made and retained as part of the storm water • pollution prevention plan for at least three years from the date that the site finally is stabilized. The report will be signed in accordance with Part VI.G of the General Permit. A copy of the signed report will be submitted to the City of Fort Worth with the Contractor's monthly pay estimate. Copies of the forms to be used for the Inspection and Maintenance Report are included in Attachment 11 as apart of this SWPPP. 5.0 Non-Storm Water Discharges a. Inventory for Pollution Prevention Plan The following substances listed below are expected to be present onsite during construction: Concrete Fuels Stone Detergents Lubricants Mortar Wood Fire Fighting Discharges Spring Water Uncontaminated Groundwater Pavement Wash Water Air conditioner Condensate A copy of the Non-Storm Water Discharge Inspection Report is Available in Attachment 12. b.

O The ends of the fence shall be turned upstream to prevent bypass of stormwater. LIMI-ATIONS Minor ponding will likely occur at the upstream side of the silt fence resulting in minor localized flooding. Fences which are constructed in swales or low areas subject to concentrated flow may be overtopped resulting in failure of the filter fence. Silt fences subject to areas of concentrated flow (waterways with flows> 1 ds)are not acceptable. Silt fence can interfere with construction operations, therefore planning of access routes onto the site is critical. Silt fence can fail structurally under heavy storm flows, creating maintenance problems and reducing the effectiveness of the system. MAINTENANCE REQUIREMENTS Inspections should be made on a weekly basis, especially after large storm events. If the fabric becomes clogged,it should be cleaned or if necessary,replaced. Sediment should be removed when it reaches approximately one-half the height of the fence.

O The ends of the dike shall be turned upgrade to prevent bypass of stormwater. O Place bales on sides such that bindings are not buried. LIMITATIONS Due to a short effective life caused by biological decomposition,straw bales must be replaced after a period of no more than 3 months. During the wet and warm seasons, however, they must be replaced more frequently as is determined by periodic inspections for structural integrity. Straw bale dikes are not recommended for use with concentrated flows of any kind except for small check flows in which they can serve as a check dam. The effectiveness of straw bales in reducing sediment is very limited. Improperly maintained,straw bales can have a negative impact on the water quality of the runoff. MAINTENANCE REQUIREMENTS Straw bales shall be replaced if there are signs of degradation such as straw located downstream from the bales, structural deficiencies due to rotting straw in the bale or other signs of deterioration. Sediment should be removed from behind the bales when it reaches a depth of approximately 6 inches.

North Central Texas Council of Governments NCTCOG Construction BMP Manual 4-25 February 1993 Section 4-Construction BMPs Triangular Sediment Filter Dike O If 85% or more of soil,by weight,passes the U.S.Standard sieve No.200,triangular sediment dike shall not be used due to clogging. O Sufficient room for the operation of sediment removal equipment shall be provided between the dike and other obstructions in order to properly remove sediment. O The ends of the dike shall be turned upgrade to prevent bypass of stormwater. LIMITATIONS Ponding will likely occur directly adjacent to the dike which may possibly cause flooding. Triangular sediment filter dikes are not effective for conditions which include substantial concentrated flows or when they are not constructed along a contour line due to the potential for flow concentration and overtopping. MAINTENANCE REQUIREMENTS Inspections should be made on a weekly basis, especially after large (> 0.5 inches) storm events. If the fabric becomes clogged,it should be cleaned or if necessary,replaced. Sediment should be removed when it reaches approximately 6 inches in depth. In addition, inspections should be made on a regular basis to check the structural integrity of the dike. If structural deficiencies are found,the dike should be immediately repaired or replaced. As with silt fence,integrity of the filter fabric is important to the effectiveness of the dike.Overlap between dike sections must be checked on a regular basis and repaired if deficient.

Smaller volumes can be used for reduced effectiveness.(See details Section 9). DESIGN CRITERIA O Filter fabric protection shall be designed and maintained in a manner similar to silt fence. O Maximum depth of flow shall be eight (8) inches or less depending on vehicular and pedestrian traffic. O Positive drainage is critical in the design of inlet protection. If overflow is not proded for at the inlet, flows which exceed the capacity of the inlet protection system shall be routed through established swales, streets or other watercourses to minimize damage due to ponding and to provide for public safety. LIMITATIONS Ponding will occur at the inlet with possible flooding as a result. Inlet protection is only viable at low point inlets.Inlets which are on a slope cannot be effectively protected because stormwater will bypass the inlet and continue downstream,causing an overload condition at inlets beyond. MAINTENANCE REQUIREMENTS Inspections should be made on a weekly basis,especially after large(>0.5 inches)storm events. When silt fence is used and the fabric becomes clogged,it should be cleaned or if necessary,replaced. Also,sediment should be removed when it reaches approximately one-half the height of the fence. If a sump is used, sediment should be removed when the volume of the basin is reduced by 50%. For systems using stone filters, when the stone filter becomes clogged with sediment, the stones must be pulled away from the inlet and cleaned or replaced. Since cleaning of gravel at a construction site may be difficult, an alternative approach would be to use the clogged stone as fill material and put new stone around the inlet.

Stabilized entrances are rather expensive considering that it must be installed in combination with one or more other sediment control techniques, but it may be cost effective compared to labor intensive street cleaning. MAINTENANCE REQUIREMENTS Inspections should be made on a regular basis and after large storm events in order to ascertain whether or not sediment and pollution are being effectively detained on site. When sediment has substantially clogged the void area between the rocks, the aggregate mat must be washed down or replaced. Periodic re-grading and top dressing with additional stone must be done to keep the efficiency of the entrance from diminishing.
