2.3. All work shall comply with codes and standards applicable to each type of work through the course of this project. The contractor shall also comply with the requirements of GSA BuildGreen standards, and PBS P- 100.

3. VISUAL CLEARANCE INSPECTION REQUIREMENTS

3.1. Visual inspections of the work area(s) shall be conducted in accordance with Section 6.4.1 of the EPA Guidance for Controlling Asbestos-Containing Materials (EPA 560/5-85-024) and the Completeness of Removal inspection in ASTM Standard E1368-14 Standard Practice for Visual Inspection of Asbestos Abatement Projects.

3.2. Final visual inspections shall be completed upon conclusion of the asbestos abatement activities to ensure the effectiveness of the controls, confirm job completeness, to ensure that the work area is visibly clean of debris, and to ensure the abatement work methods complied with applicable regulations and GSA protocols.

3.3. Final visual inspections shall include the entire work area(s) including all surfaces, ceilings, walls, flooring, decontamination units, remaining plastic sheeting / critical barriers, etc. looking for debris from any source, residue on surfaces, dust, or other matter.

3.4. If the area does not pass visual inspection, the abatement contractor shall be directed to re-clean the area at no additional cost, and the process will be repeated until clearance is achieved.

4. FINAL AIR MONITORING CLEARANCE REQUIREMENTS

4.1. Where feasible, five (5) aggressive air clearance samples per containment / regulated area shall be collected. For smaller work areas and multiple glove bags in a single functional space, please consult with the GSA OFM Industrial Hygiene Group for clearance sample requirements.

4.2. Air samples collection methodology shall be in accordance with the NIOSH 7400 PCM method.

4.3. Air samples shall be collected on open-faced, 0.8-micron, 25-millimeter (mm), mixed cellulose ester (MCE) filter air sampling cassettes using electric high-volume sampling pumps.

4.4. Air sampling cassettes shall be placed on a sampling stand to achieve cassette heights between 3 to 5 feet above floor level and with the cassette opening orientated downward at a 45° angle.

4.5. Each air sampling pump shall be calibrated with the cassette in-line with a rotameter before and after air sampling; adjusting the flow as necessary to obtain the desired flow rate. Rotameters shall be properly calibrated against a primary standard.

4.6. Sample flow rates shall be approximately 10 liters (L) per minute.

4.7. A minimum sample volume of 1,200 liters (L) per sample shall be collected.

Version 1.0, May 2022 Page 3

4.8. An appropriate number of field blanks shall be used pursuant with the NIOSH Method 7400.

4.9. Asbestos air sample analysis shall be conducted either onsite by a NIOSH 582 trained microscopist participating in the American Industrial Hygiene Association Proficiency Analytical Testing (PAT) Program for PCM or performed by an American Industrial Hygiene Association (AIHA) and/or National Institute of Standards and Technology (NIST) National Voluntary Laboratory Accreditation Program (NVLAP) -accredited analytical laboratory.

4.10. Final clearance sample results shall be compared to the AHERA PCM clearance criteria threshold of

0.01 fibers per cubic centimeter (f/cc).

4.11. Work area shall not be cleared or abatement contractor released until all final air clearance samples collected are less than the clearance criteria. If clearance samples fail, please contact GSA Project Manager and Regional Industrial Hygienist for direction. The regulated area may have to be re-cleaned or re-cleared or samples reanalyzed by TEM.

5. DELIVERABLE REQUIREMENTS
