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 (ACP) in compliance with NESHAP. Nothing in th is 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 . The Generator of the hazardous material is responsible for the identification and proper handling, transportation , and disposal of the material. Therefore, it is the policy of the City of Fort Worth that the Excavator is the Generator regardless of whether the pipe is friable or not. 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} 11129104 SC-56 - - - - PART D -SPECIAL CONDITIONS F.

The appropriate blanks in Section A must be filled out by all out-of-state or non resident bidders in order for your bid to meet specifications. The failure of out-of-state or non- resident contractors to do so will automatically disqualify that bidder. Resident bidders must check the box in Section B. A. Non-resident vendors in (give state), our principal place of business, are required to be ___________ _ percent lower than resident bidders by state law. A copy of the statute is attached. Non-resident vendors in (give state), our principal place of business are not required to underbid resident bidders. B.

Pl.~TEJS TECHNICAL MEMORANDUM Geotechnical Properties -Southside II Water Transmission Main PREPARED FOR : PREPARED BY : COPIES : DATE : Introduction Doug Biglen, P.E ./DFW Robert K. Cullwell, P.E./SAN Steve Smith, P .E./ AUS January 17, 2005 CH2MHILL On November 5, 2004, Fugro Consultants, LP (Fugro), performed Geotechnical sampling along the proposed a lignment for the Southside II Water Transmission Main, in Fort Worth, TX. Approximately 22 borings were drilled. The resulting soil samples were transferred to the Fugro facility in Dallas, Texas for laboratory t esting. Laboratory Analysis and General Lithology A summary of the laboratory results, and general lithology is as follows : Stratum Soil Type Dark Brown, Brown, Stratum I Reddish Bro wn CLAY (CH), w ith Trace Sand. FIL L: Dark Bro wn, Stratum Ia Brown CLAYS (CH - CL), w ith trace sand and limestone fragments Ye ll owish Brow n , Brown, Dark Brown Silty Cla y Stratum II (CL), w ith trace sand, calcareous n odules, and limestone fra g ments Stratum Tan LIME STONE, with clay seam s, weathered to III hard .

These clays are in a slightly moist to wet condition. They are considered soft to hard with pocket penetrometer values ranging from 1.0 to 4.5 ts£. Unconfined compression tests within this zone range from 0.4 to 4.9 tons per square feet. Minus #200 laboratory tests indicates these materials generally contain 31 to 88 percent clay and silt sized particles. The low minus #200 test value of 31 suggests intermittent sand seams may exist within this zone. Stratum Ia: This stratum is comprised of unclassified fill material. Laboratory tests indicate these fill materials are highly plastic clayey soils with a PI of 44. These clays are in a slightly moist to wet condition. They are considered soft to hard with pocket penetrometer values ranging from 1.5 to 4.5 ts£. Unconfined compression tests within this zone range from 1.4 to 1.5 tons per square feet. Minus #200 laboratory tests indicates these materials generally contain approximately 64 percent clay and silt sized particles . Stratum II: This stratum is comprised of low to moderate plastic (silty to sandy) clay soils with Plasticity Indices ranging from 16 to 23. These clays are in a slightly moist to wet condition. They are considered soft to hard with pocket penetrometer values ranging from 1.0 to 4.5 ts£. Unconfined compression tests within this zone range from 1.2 to 3.5 tons per square feet. Minus #200 laboratory tests indicates these materials generally contain 70 to 85 percent clay and silt sized particles. Stratum Ill: This stratum is comprised of limestone. The surface limestone appears to be slightly weathered with clay and silt seams. The limestone materials are hard with SPT "N" values ranging from 100 blows per 3.5" of penetration to 100 blows per 0.75" of penetration. Ground Wate r Groundwater was encountered in 3 of the 22 boring drilled along the alignment. The groundwater occurrence is as follows: Boring Approx.

Based on the provided data from Fugro a project specific recommendation can not be provided. General values of (E') are provided in the following table: Proposed Bedding Material Modulus of Soil Reaction E' (psi) No compaction Compacted to 90 % of standard proctor On-site Soils 50 400 Clean (Washed) Gravel 200 2,000 Crushed Limestone Base 1,000 3,000 Summary and Co nclusions Nearly all of the boring data provided by Fugro t erminated below the invert of the proposed pipeline. The pipeline w ill traverse through varied lithology including undocumented fill material, clay, silty clay, and limestone. For the purposes of pipeline design the worst soil condition (Fill) should be assumed. Conversely, Limestone was observed above the pipeline invert in m any loc a tions . Construction in these areas will require rock excavation equipm ent. Ground water was observed in borings B-7, B-14, B-15. The presence of groundwater at B-7 appears to be the result of IH-35 drainage at Sta. 80+50. The groundwater occurrence in B- 14 and B-15 appears to be associated with an un-named creek crossing of the pipeline alignment at approximate Sta. 193+00. During the d esign process, the affects of groundwater should be acco unte d for approximately 1,500 feet upstream and downstream from these p oints. CHREPORT _JAN_ 18_2005.DOC 3
