  Note: The party conducting the project shall determine the method of analysis which will be utilized to meet the air sampling requirements of this Part (rule). Phase Contrast Microscopy (PCM) is the minimally acceptable method of analysis which may be elected. Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) are other acceptable methods of analysis. Whichever methodology is selected must be used consistently for pre-abatement, abatement and post-abatement monitoring. However, where the use of PCM has resulted in fiber counts which exceed the air clearance levels acceptable under this Part (rule), TEM may be utilized to obtain a more accurate asbestos fiber count. Where such election is made, both the PCM and TEM results must be made available to the commissioner or his/her designee in accordance with the provisions of this Part (rule).

*Required on glovebag or tent failure or loss of integrity.

§ 56-17.2   Pre-abatement and post-abatement monitoring (clearance air monitoring).

     (a)   Drying time.  Sampling shall not commence until:

     (1)  at least 12 hours after wet cleaning has been completed; and

     (2)  no visible pools of liquid or condensation remain.

     (b)   Number of samples - large asbestos projects.  For large asbestos project pre-abatement and post-abatement monitoring (clearance air monitoring), a minimum of five area samples inside and five area samples outside each homogeneous work area shall be taken.

     (c)   Additional samples.  In addition to the five-sample minimum requirement set forth in subdivision (b) of this section, one representative area sample, for every 5,000 square feet above 25,000 square feet of floor space, shall be taken.

     (d)   Number of samples - small asbestos projects.  For small asbestos project pre-abatement and post-abatement monitoring, a minimum of three samples inside and three samples outside the work area shall be taken.

     (e)   Placement of air-sampling equipment.  Air-sampling equipment shall not be placed in corners of rooms or near obstructions. Within the above constraints, samplers shall be placed at random around the work area. If the work area contains the number of rooms equivalent to the number of required samples based on floor area, place a sampler in each room. When the number of rooms is greater than the required number of samples, a representative sample of rooms shall be selected.

     (f)   Aggressive sampling techniques.  The following aggressive sampling techniques shall be used for all clearance air monitoring:

     (1)  Presampling agitation.  Before starting the sampling pumps, the exhaust of forced-air equipment shall be directed against all walls, ceilings, floors, ledges and other surfaces in the rooms. This shall continue for at least five minutes per 1,000 square feet of floor.

     (2)  Ongoing agitation.  At least a 20-inch fan shall be placed in the center of each room. One fan per 10,000 cubic feet of room space shall be used. The fan shall be operated on slow speed and pointed toward the ceiling.

     (3)  Begin sampling.  The sampling pumps shall then be turned on.

     (4)  End sampling.  When sampling has been completed, the sampling pumps shall be turned off first, followed by the fan.

     (g)   Air changes.  During clearance air monitoring, the negative air pressure equipment shall be operated at a maximum of two air changes per hour.

     (h)   Samplers outside of the work area.  For clearance air monitoring, the samplers, placed outside the work area but within the building or structure, shall be so located as to avoid any air that might escape through the isolation barriers.

Note:   Minimum distances should be at least 50 feet from the entrance to the work area and 25 feet from the plastic barriers.

     (i)   Placement of outdoor samplers.  Outdoor background samplers shall be placed at approximately grade level six feet above and away from obstructions that may influence wind patterns. If access to electricity and concerns about security dictate a rooftop site, locations near vents or other structures on the roof shall be avoided.

Historical Note:  Sec. filed July 7, 1987; amd. filed Oct. 18, 1991 eff. Jan. 1, 1992.

§ 56-17.3   Air sampling during abatement.

     (a)   Sample locations—large asbestos projects.  Once abatement activities have begun, the following schedule of samples shall be required, as a minimum, for large asbestos projects on a daily basis.

Note:  The size of the abatement activity will determine the number of samples necessary.
     (1)  Two area samples shall be taken outside the work area and the enclosures, but within the building or structure, in uncontaminated areas that are within 10 feet of the isolation barriers. Where negative ventilation exhaust ducts run through uncontaminated areas, one of the area samples shall be taken in one of these areas. Where adjacent nonwork areas do not exist, an additional exterior area sample, remote from that in paragraph (3) of this subdivision, shall be taken.

     (2)  One area sample shall be taken outside the work area, in uncontaminated areas that are within 10 feet of and within the actual environment of the entrance/exit of each personal decontamination and waste decontamination enclosure.

     (3)  One area sample shall be taken outside the building or structure.

     (4)  One area sample shall be taken within 10 feet of each unobstructed, negative pressure ventilation equipment exhaust.

Historical Note:  Sec. filed July 7, 1987; amd. filed Oct. 18, 1991 eff. Jan. 1, 1992.

§ 56-17.4   Air sampling and analysis.

     (a)   Air sampling and analysis.  Air sampling and analysis shall not be performed by any party involved with the asbestos project, except as follows: Air sampling and analysis shall not be performed by any party involved with the asbestos project, except as follows:

     (1)  The individual or firm acting as the project monitor may perform air sampling and analysis so long as the individual or firm acting as the project monitor has not performed any other function on the project.

     (2)   Any party to the project, other than the abatement contractor, may perform air monitoring functions on the project provided that:(i) all air samples shall be analyzed at an independent laboratory conforming to the requirements of section 56-17.4(c) of this Subpart; and (ii) copies of all air clearance monitoring results shall be furnished pursuant to section 56-17.8 of this Subpart; and (iii) the name and address of the laboratory performing analysis shall be provided to the commissioner in accordance with section 56-1.8(e)(5) of this Part.

     (b)   Qualifications of person(s).   The air sampling shall be conducted by an industrial hygienist, air sampling technician or air sampling technologist who has been trained in the selected methodology of sampling and analysis of asbestos and who possesses an asbestos project air sampling technician certificate issued by the department.

     (c)   Certification of laboratory.  The laboratory used for analysis shall be one accredited by the AIHA or by the New York State Department of Health for the selected methodology of sampling and analysis of asbestos.

     (d)   Consistency of methodologies.  The selected methodology of sampling of asbestos shall be consistent with the selected methodology of analysis.
