N.Y. Comp. Codes R. & Regs. Tit. 12 §§ 56-8.1 - Air sampling requirements

(a) Personal air sampling. Air sampling shall be performed in the worker's breathing zone, by the asbestos contractor for his personnel, as required by current OSHA regulations.

(b) Daily air sampling. Project air sampling shall be conducted daily for the full workshift for large projects. If more than one daily workshift is required to accomplish the work, air sampling shall be performed on each workshift. Air sampling is not required on days when there are no Phase II B activities.

(1) Number and location of samples -- large asbestos projects. A minimum of five samples shall be taken on a daily basis. The locations of samples to be taken are the same as specified for Phase II A. (See section 56-7.1 and table 2 within section 56-4.9 of this Part.)

(2) Work stoppage criteria during Phase II B abatement procedures. If air samples collected outside the regulated abatement work area, indicate airborne fiber concentrations at or above 0.01 fibers per cubic centimeter, or the established background level, whichever is greater, work shall stop immediately for inspection and repair of barriers and negative air ventilation systems as necessary. Clean up of surfaces outside of the regulated abatement work area using HEPA-vacuums and wet-cleaning methods shall be performed prior to resumption of abatement activities. A summary of clean up activities and the results of barrier inspections including any necessary repairs, shall be documented in the supervisor's daily project log. Work methods shall be altered accordingly to reduce fiber concentrations to acceptable levels.

(c) Exemption from daily air sampling. Daily air sampling is not required on exterior asbestos projects with abatement of non-friable ACM roofing, siding, caulking or glazing compound, tars, sealers, coatings or other NOB ACMs, unless the ACM is rendered friable during removal or debris falls inside the building/structure.
