15 RCNY § 1-111 Preliminary Clean-up Procedures.

§ 1-111 Preliminary Clean-up Procedures. The following clean-up requirements shall be followed during the conduct of abatement activities on asbestos projects: (a) (1) All waste generated shall be bagged, wrapped or containerized immediately upon removal. The personal and waste decontamination enclosure systems and floor and scaffold surfaces shall be HEPA vacuumed and wet cleaned at the end of each work shift at a minimum. (2) Visible accumulations of asbestos-containing waste material shall be containerized utilizing non-metallic dust pans and non-metallic squeegees or HEPA vacuums. (3) Metal shovels shall not be used to pick up or move accumulated asbestos-containing waste material or any other debris in the vicinity of isolation or surface barriers. (b) The waste decontamination enclosure system shall be wet cleaned twice using wet cleaning methods upon completion of waste removal. When the worker decontamination enclosure shower room alternates as a waste container wash room, the shower room shall be washed immediately with cloths or mops saturated with a detergent solution prior to wet cleaning. (c) The worker decontamination enclosure system shall be wet cleaned / HEPA vacuumed, as appropriate, after each shift change and meal break. (d) If there is free standing water or if flooding occurs in the work area, work must stop until the water is collected and safely and properly removed. (Amended City Record 12/7/2018, eff. 1/6/2019)

15 RCNY § 1-112 Additional Clean-up Procedures (Final).

§ 1-112 Additional Clean-up Procedures (Final). Additional clean-up procedures shall be performed in the order set forth below prior to commencement of clearance air monitoring. (a) After removal of visible accumulations of asbestos-containing waste material, all surfaces must be HEPA vacuumed. To pick up excess water and saturated debris, a wet-dry shop HEPA vacuum, dedicated to asbestos abatement, may be used. (b) All surfaces in the work area shall be wet cleaned (first cleaning). (c) A thin coat of lockdown encapsulant shall be applied to all surfaces in the work area which were not the subject of removal or abatement, including the cleaned layer of the surface barriers and excluding sprinklers, standpipes, and other active elements of the fire suppression system. (d) After the first cleaning, the work area shall be vacated for 12 hours to allow fibers to settle. (e) The cleaned and encapsulated layer of the surface barriers shall be removed from the walls and floors. (f) All objects and surfaces in the work area shall be HEPA vacuumed and wet cleaned a second time. (g) After the second cleaning, the work area shall be vacated for 4 hours before wet cleaning and/or HEPA vacuuming all surfaces in the work area for a third cleaning. (h) After the plastic barriers on the walls and floors have been removed, a third cleaning shall be performed of all surfaces in the work area by wet cleaning and/or HEPA vacuuming. A minimum of a one hour waiting period shall be conducted to allow the work area to dry prior to the visual inspection by the air monitor and asbestos supervisor. (i) Before starting clearance air monitoring, a thorough visual inspection must be conducted to verify the absence of asbestos-containing waste material (e.g. dust). This inspection must be documented in the project air sampling log. (j) All containerized waste shall be removed from the work area through the decontamination enclosures and the holding area. (k) All tools and equipment shall be removed from the work area and decontaminated in the waste decontamination enclosure system. Cloths, mops, and other cleaning aids shall be disposed of as asbestos-containing waste material. (l) After successful clearance air monitoring (see 15 RCNY §§ 1-31 et seq.), the isolation barriers shall be removed and the remaining worker and waste decontamination enclosure(s) must be dismantled and removed from the work site. All plastic sheeting must be cleaned using a HEPA vacuum and disposed of as asbestos contaminated waste. (m) Within 21 days of the completion of all steps set forth above, including successful clearance air monitoring, a project monitor’s report (Form ACP15) must be submitted to DEP. Failure to submit the ACP15 Form will result in suspension of the air monitor’s account and the contractor’s account in the ARTS E-File System until the form is submitted. This report must be based on an inspection performed after the completion of all steps listed in this section, and may not be based on the visual inspection performed prior to the commencement of clearance air monitoring. This inspection must be documented in the project air sampling log. The project monitor who prepares the report must be independent of the abatement contractor. If a project is being performed on multiple floors of a building, a separate project monitor’s report may be submitted as each floor is completed. Compliance with this subdivision is the responsibility of the building owner.
