7. Although regulations may not require special waste disposal waste disposal in certain situations, some landfills place restrictions on the methods and packaging for receiving

Category I non-friable wastes. It is the AC’s responsibility to make disposal arrangements for the wastes it generates and to include such arrangements in its scope of work.

3.9 Asbestos Waste Disposal Procedures:

A. Package, label, and remove all asbestos waste from the Work Area as specified below. Packaging shall be accomplished in a manner that minimizes waste volume but ensures waste containers shall not tear or break. Transportation and disposal of the containerized waste at a landfill previously accepted by the Engineer shall be the responsibility of the AC.

B. Waste Labeling:

1. Warning labels, having waterproof print and permanent adhesive in compliance with OSHA, EPA and Department of Transportation requirements, shall be affixed to or printed on the sides of all waste bags or transfer containers. Warning labels shall be conspicuous and legible.

2. In compliance with NESHAPS, 40 CFR, Part 61.150, all waste containers or bags shall be labeled in accordance with applicable regulations and include the name of waste generator and location of where waste was generated.

C. Wetting of Waste: A fine water spray shall be used to keep the top layers of waste in containers thoroughly wet at all times. When a waste bag is full, air within the bags shall be evacuated with a HEPA equipped vacuum and be securely sealed with tape or other secure fastener.

D. Waste Container Storage: The container used for the storage of bagged contaminated waste shall be an enclosed dumpster. Line the cargo area with two layers of a 6 mil polyethylene sheeting to prevent contamination from damaged or leaking containers. Floor sheeting shall be installed first and shall extend up the sidewalls 24 inches minimum. Wall sheeting shall be overlapped and taped securely into place. No un-bagged contaminated waste or non-asbestos waste shall be stored in these dumpsters. Ensure that bags placed in dumpsters are undamaged. Warning signs shall be posted on the dumpster in accordance with Sections 29 CFR 1926.1101 of the OSHA regulations.

E. Waste Removal Scheduling: All waste containers generated during asbestos removal operations shall be decontaminated and removed from the work area before final cleanup is started and isolation barriers are taken down. No waste shall be removed without the hygienist being present.

Receipts shall be submitted to Owner within NESHAPS specified timeframes, and prior to the time of request for final payment.

G. Waste Transportation and Disposal Regulations: It is the responsibility of the AC to determine and ensure that AC is complying with 1) the current waste handling regulations applicable to each work site; and 2) the current regulations for transporting and disposing waste at each ultimate disposal landfill. The AC must comply fully with these regulations; and with all U.S. Department of Transportation, state, local, and EPA requirements.

H. Only landfills approved and permitted by Texas for accepting asbestos wastes shall be used for disposal.

I. Waste Shipment Records (WSR): The AC shall be responsible for supplying, preparing and signing all WSRs using a multi-part carbonless form set in the form specified in 40 CFR 61.149 figure 4, as required by 40 CFR 61.150 (d)(1).

1. On the date of shipment, the AC’s Authorized Agent shall sign the WSR as the operator and record waste information (type and quantity of waste) on the WSR. The Hygienist will initial the WSR prior to the shipment leaving the site. A copy of the WSR (part of the multi-part

WSR form), shall be provided to the Hygienist prior to the waste leaving the site.

2. In the event a WSR is not returned within 45 Days of the waste leaving the Site, the AC shall be responsible for notifying the EPA of the discrepancy and take immediate measures to locate the waste. If the waste is not received by the disposal facility within applicable regulatory time frame, the AC is responsible for determining the location of the waste and immediately reporting all information regarding the waste to the Engineer and the Owner. If the Engineer does not receive the WSR within five (5) days, the Engineer shall notify the AC and shall suspend further waste shipments. The AC shall be required to provide written documentation of the location of the waste associated with the missing WSR within five (5) days of being notified by the Engineer.

B. Wet clean all surfaces and remove excess water. Remove outer layer of poly and dispose as ACM waste. Completion of the final Clean shall be determined and documented by the IH.

C. Visual inspection: IH and AC shall jointly inspect the work area for visible residue and excess water and, if observed, repeat the clean cycle until residues are not detected and work area is dry.

D. Apply lock-down encapsulants after all the asbestos flooring and associated mastics are removed, bagged and area clean up, free of debris and excess water removed and dry.

3.11 Final Clearance
