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 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. 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) an F.

The Texas Commission on Environmental Quality(TCEQ), in coordination with the National Weather Service, will issue the Air Pollution Watch by 3:00 p.m. on the afternoon prior to the WATCH day. On designated Air Pollution Watch Days, the Contractor shall bear the responsibility of being aware that such days have been designated Air Pollution Watch Days and as such shall not begin work until 10:00 a.m. whenever construction phasing requires the use of motorized equipment for periods in excess of 1 hour. However, the Contractor may begin work prior to 10:00 a.m. if use of motorized equipment is less than 1 hour, or if equipment is new and certified by EPA as "Low Emitting`, or equipment bums Ultra Low Sulfur Diesel (ULSD), diesel emulsions, or alternative fuels such as CNG. If the Contractor is unable to perform continuous work for a period of at least seven hours between the hours of 7:00 a.m. -6:00 p.m., on a designated Air Pollution Watch Day, that day will be considered as a weather day and added onto the allowable weather days of a given month. D-73 FEE FOR STREET USE PERMITS AND RE-INSPECTIONS A fee for street use permits is in effect. In addition, a separate fee for re-inspections for parkway _ construction, such as driveways, sidewalks, etc., will be required. The fees are as follows: 1. The street permit fee is $50.00 per permit with payment due at the time of permit application. 2. A re-inspection fee of $25.00 will be assessed when work for which an inspection called for is incomplete. Payment is due prior to the City performing re-inspection. Payment by the contractor for all street use permits and re-inspections shall be considered subsidiary to the contract cost and no additional compensation shall be made. .. om .. .. 1W7104 SC-54 ..

This pilot hole shall serve as the centerline of the larger diameter hole to be bored. Other methods of maintaining line and grade on the casing may be approved if acceptable to the Engineer. Excavated material shall be placed near the top of the working pit and disposed of as required. The use of water or +� other fluids in connection with the boring operation will be permitted only to the extent required to lubricate cuttings. Jetting or sluicing will not be permitted. r b: In unconsolidated soil formations, a gel-forming colloidal drilling fluid consisting of at least 10 percent of high grade carefully processed bentonite may be used to consolidate cuttings of the bit, seal the walls of the hole, and furnish lubrication for subsequent removal of cuttings and installation of the pipe immediately thereafter. C. Allowable variation from the line and grade shall be as specified under paragraph A.2. All voids between bore and outside of casing shall be pressure grouted. 11/02104 ASC-5 PART DA - ADDITIONAL SPECIAL CONDITIONS 4. Installation of Carrier Pipe in Casing: a. Sanitary sewer pipe located within the encasement pipe shall be supported by "skids" or "bands" to prevent the pipe and bells from snagging on the inside of the casing, and to keep the installed line from resting on the bells. b. All skids shall be treated with a wood preservative. Skids should extend for the full length of the pipe with the exception of the bell area and spigot area necessary for assembly unless otherwise specified. C. The Contractor shall prevent over-belling the pipe while installing it through the casing. A method of restricting the movement between the assembled bell and spigot where applicable shall be provided. d. At all bored, jacked, or tunneled installations, the annular space between the carrier pipe and casing shall be filled with grout. Care must be taken that not too much water is forced into the casing so as not to float the pipe. The backfill material will not be required unless specified on the plans and specified by the Engineer. F e. Closure of the casing after the pipe has been installed shall be plugged at the ends of the casing as shown on the drawings or as required by the Engineer. ,. 5. Boring and Jacking Ductile Iron Pipe without Casing Pipe: a. As indicated on drawings and as required and directed by the Engineer sewer shall be constructed of bore and jacked ductile iron pipe. b. When a casing pipe is not designated on the drawings, the contractor shall provide a casing pipe if necessary to achieve line and grade. Casing pipe shall be provided at no additional cost and shall be subsidiary to the cost bid for installation By Other than Open Cut. C. Bore and jack in accordance with paragraph C.3. above. d. Short length of sewer consisting of a single pipe section may be installed by jacking without a bore hole if permitted by the Engineer and in soft soil layer. All voids outside of installed pipe shall be pressure grouted. 6. Tunneling: Where the characteristics of the soil, the size of the proposed pipe, or the use of monolithic sewer would make the use of tunneling more satisfactory than jacking or boring, or when shown on the plans, a tunneling method may be used, with the approval of the Engineer or railroad/highway officials. a. When tunneling is permitted, the lining of the tunnel shall be of sufficient .E strength of support the overburden. The Contractor shall submit the proposed liner method to the Engineer for approval. The tunnel liner design shall bear the seal of a licensed professional engineer in the State I tea ASO-6 PART DA - ADDITIONAL SPECIAL CONDITIONS of Texas. Approval by the Engineer shall not relieve the Contractor of the responsibility for the adequacy of the liner method. b. The space between the tunnel liner and the limits of excavation shall be pressure grouted or mud jacked. C. Access holes for placing concrete shall be space at maximum intervals of 10 feet. .. D. MEASUREMENT AND PAYMENT: Installation of pipe by other than open cut will be measured by the linear foot of pipe, complete in place. Such measurement will be made between the ends of the pipe along the central axis as installed. The work performed and .. materials furnished as prescribed by this item will be paid for at the Contract Unit Price bid per linear foot for Pipe Installed by Other Than Open Cut of the type, size, and class of pipe specified as shown on plans. The furnishing of all materials, pipe, liner materials required for installation, for all preparation, hauling and installing of same, and for all labor, tools, equipment and incidentals necessary to complete the work, including excavation, backfilling and disposal of surplus material shall be included in the Contract Unit Price as shown in the Bid Proposal.
