§ 1-128 Clean-up Procedures: Preparation for Clearance Air Monitoring.
RCNY § 1-128
The following final clean-up procedures for pre-demolition abatement shall be performed prior to commencement of clearance air monitoring: (a) All visible accumulations of asbestos-containing waste material shall be removed and containerized. Metal shovels may be used to pick up or move accumulated waste EXCEPT in the vicinity of plastic sheet isolation and surface barriers which could be perforated by these tools. The areas around the plastic sheet isolation barriers shall be cleaned of visible accumulations utilizing rubber dust pans and rubber squeegees. To pick up excess water and gross wet debris, a wet-dry shop HEPA vacuum dedicated to asbestos abatement may be used.
(b)All containerized waste shall be removed from the work area through the decontamination enclosures and the holding area.
(c)All surfaces in the work area shall be wet cleaned using rags or mops. After allowing sufficient time for drying of the work area, HEPA vacuums shall be used to thoroughly clean all surfaces after gross clean-up.
(d)The plastic sheeting installed, pursuant to 15 RCNY § 1-125(j), must be cleaned as in subdivision (c) above, then sprayed with a lockdown encapsulant and removed when dry.
(e)All surfaces in the work area which were not the subject of removal or abatement shall be sprayed with a lockdown encapsulant, which upon drying will not dissolve upon rewetting. Sufficient time for drying shall be allowed.
(f)All tools and equipment shall be removed from the work area and decontaminated in the equipment decontamination enclosure system.
(g)After successful clearance air monitoring (see 15 RCNY §§ 1-31 et seq.), a HEPA vacuum must be used to clean up any dust or debris when removing the isolation barriers.
(h)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. (Amended City Record 12/7/2018, eff. 1/6/2019; amended City Record 1/15/2025, eff. 2/14/2025)
