§ 1-102 ACM Disturbance, Handling and Removal Procedures.
RCNY § 1-102
The following procedures shall be followed during the conduct of abatement activities: (a) Abatement of asbestos-containing materials shall be by wet methods. ACM shall not be removed or disturbed without being adequately wet. Dry removal of asbestos-containing material is prohibited, unless EPA approval has been obtained. The EPA-approved alternate removal plan shall be submitted to the Department for approval a minimum of 15 days before work is scheduled to begin or begins. The plan shall explain and justify why ACM must be removed dry and how asbestos fibers will be controlled to prevent their release.
(b)When amended water is used, the ACM must be sprayed with sufficient frequency and quantity for enhanced penetration. Sufficient time must be allowed for penetration to occur prior to removal action or other disturbance taking place. Accumulation of standing or free water is prohibited. Soft loosely bound ACM must be saturated. Material that resists wetting, such as tremolite or amosite, must be thoroughly wetted on all surfaces while work is being conducted.
(c)When used, removal encapsulants that minimize fiber generation and enhance penetration, shall be applied per manufacturer's specifications and in accordance with federal guidelines.
(d)ACM on detachment from the substrate is to be bagged directly or dropped onto a flexible catch basin and promptly bagged. Detached ACM is not permitted to lie on the floor for any period of time. Excess air in the bag must be minimized and the bag must be sealed. Material that resists wetting must not be dropped. ACM must not be dropped from a height greater than 10 feet. Above 10 feet in height dust-free enclosed inclined chutes may only be used inside a work area that is under negative pressure. Vertical chutes are prohibited. The angle of the chute must not exceed 60 degrees from horizontal.
(e)Large components removed intact that cannot be containerized shall be maintained wet, wrapped (minimizing excess air) in at least one layer of fire retardant 6-mil polyethylene sheeting, and secured by sealing with tape.
(f)After completion of all stripping work, surfaces from which asbestos-containing materials have been removed shall be cleaned (e.g. wet-brushed and/or wet-cleaned) to remove all visible residue. (Amended City Record 12/7/2018, eff. 1/6/2019; amended City Record 4/28/2022, eff. 5/28/2022)
