(a) Bulk sampling requirements.
(1) Bulk samples shall be taken by whatever method minimizes the potential for fiber release.
(2) Any material which remains exposed as a result of the sampling procedure shall be sealed.
(b) Area air sampling requirements. Area air sampling equipment for Phase Contrast Microscopy (PCM) shall be utilized in accordance with the equipment and sampling procedures specified within the NIOSH 7400 Method modified for area sampling.
(c) Area air sampling equipment for Transmission Electron Microscopy (TEM) shall be utilized in accordance with the sampling procedures specified within 40 C.F.R. Part 763, Subpart E, Appendix A – Section II Mandatory Transmission Electron Microscopy Method, Subsection B - Sampling.
(d) Air sampling pumps must have a constant controlled flow and must have the flow rate capacity to perform sampling as specified in these rules. A properly calibrated rotometer must be used to check the flow rate. A rotometer, along with its current calibration sheet, must be available at the work place for the duration of air sample collection. Primary and secondary calibration devices must be calibrated as per NYSDOH ELAP requirements.
(e) Sampling pumps, cassettes, and tubing shall be checked before, during and after use. Cassettes must be labelled with a sample identification number prior to the commencement of air sampling. The sampling assembly shall be checked for leaks and occlusions throughout the shift and documented in the project air sampling log by the Asbestos Project Air Sampling Technician or project monitor.
(f) A project air sampling log must be created and maintained in a permanently bound book by the air monitoring company. The project air sampling log must be available at the work site. A copy of the project air sampling log must be submitted to the department within 72 hours of request. The project air sampling log must contain the following information for all area air samples collected on the asbestos project:
(1) Name of the company and the Asbestos Project Air Sampling Technician performing the project air sampling, per work shift or day for all area air samples collected.
(2) Dates of project air sample collection, per work shift or day of area air samples, with appropriate reference to the work area to which the air samples apply.
(3) Sample location sketch, showing the sample ID numbers, identifying all project air sample locations, per work shift or day of area air samples. The sketch must be made within one hour of the beginning of sample collection.
(4) Flow rate primary or secondary calibration device identification number, method of flow rate primary or secondary device calibration and date of last calibration, per work shift or day of area air samples.
(5) Flow rate of sampling pumps with pre and post calibration listed for each area air sample collected.
