Project Monitoring:
Project Monitoring: Throughout the decontamination activities, project air monitoring will be conducted in addition to the Perimeter Monitoring described above. Project Monitoring will be conducted in strict accordance with RCNY Title 15 Chapter 1, Section 1-41 to 1-45, with the exception that all sample analyses will be by TEM.
Clearance Testing: Aggressive area clearance testing for asbestos will be conducted for all work areas by TEM. Aggressive clearance testing for metals will be conducted by NIOSH 7300.
Clearance Criteria
Clearance testing for asbestos will be acceptable when all samples for a given work area meet the 70 structures per square millimeter TEM standard. Clearance testing for metals will be acceptable when all samples meet the following criteria:
Antimony 250 ug/m3 Barium 250 ug/m3 Beryllium 1.0 ug/m3 Cadmium 5.0 ug/m3 Chromium (III) 250 ug/m3 Copper 500 ug/m3 Lead 25 ug/m3 Manganese 100 ug/m3 Mercury 12.5 ug/m3 Nickel 50 ug/m3 Zinc 1,000 ug/m3
Structural Framing:
Due to the impossibility of removing structural framing without the risk of building collapse, all structural framing will be wet-wiped, HEPA vacuumed, and encapsulated with penetrating encapsulant. As a part of the conventional demolition that will follow the decontamination, these materials will be characterized for asbestos content and RCRA characteristics, and will be disposed of as appropriate based on the test results.
Thank you for your time and consideration,
Sincerely, f(ie4e€ o't&% Michael Porter Senior Project Manager
