NYC 9/11 Public Portal Document

(a) Timing of Waste Transfer Activities. During Phase II B of the project, after ACM, PACM, asbestos material and debris is bagged, wrapped, or containerized, waste transfer from the regulated abatement work area as per this Section, shall occur when no gross removal is taking place.

(b) First Cleaning. External surfaces of contaminated bags/containers and equipment shall be cleaned by wet wiping or HEPA-vacuuming or both in the regulated abatement work area before moving such items into the waste decontamination system washroom by persons assigned to this duty.

(1) Exception. Minor size regulated abatement work areas that do not have a contiguous washroom, are allowed to have all waste bag/container cleaning with additional containerization completed within that work area. The waste generated shall be immediately bagged/containerized within the regulated abatement work area. Once the abatement and cleaning is complete within the regulated abatement work area, each waste bag/container shall be wet-wiped, placed in a second bag/container and sealed airtight (except for non-porous drums which shall be washed and dried only), then moved to the airlock. The waste bags/container shall then be transferred to the secured waste trailer/dumpster for disposal by appropriate legal method.

(c) Washroom Procedures. All bagged/containerized contaminated items and asbestos waste shall be passed into the washroom during waste transfer operations. Workers from uncontaminated areas in full protective clothing and appropriate respiratory protection shall enter the washroom and place the appropriate supply of specified clean waste bags/containers within the washroom. One team of workers shall be stationed in the washroom for bag/container cleaning and additional containerization as necessary. The workers shall ensure all curtained doorways are closed during the waste container transfer procedure and that all bags/containers are sealed properly before removing for transport and disposal. (1) Additional Cleaning. Once in the waste decontamination system, external surfaces of the contaminated bags/containers and equipment shall be cleaned an additional time by wet cleaning in the washroom. (2) Additional Containerizing. Once the additional cleaning is completed and the cleaned bags/containers of asbestos waste are dried of any excessive pooled or beaded liquid, they shall be placed in a clean uncontaminated plastic bag or wrapped in sheeting (except for non-porous drums which shall be washed and dried only), as the items physical characteristics demand, and sealed airtight. When the bags/containers are moved to the holding area, lockable trailer, or lockable hardtop dumpster, the bags/containers shall be appropriately labeled with the date they are moved from the waste decontamination system marked on the container in waterproof markings. Caution labels as per the requirements of current ERA NESHAP regulations shall also be affixed at this time.
