A minimum of 2 layers of 6-mil polyethylene sheeting shall be installed on all interior walls and floors in the unit. Install black sheeting as necessary for privacy. Construct each section of the unit with sufficient size to adequately accommodate decontamination and other work activities. Provide flap doors separating each section of the unit. Fabricate from two (2) overlapping sheets with openings a minimum of three feet (3') wide. Configure so that sheeting overlaps adjacent surfaces. Weigh sheets at bottoms as required so that they quickly close after being released. One sheet shall be secured at the top and left side, the other sheet at the top and right side.

The name of the waste





generator (Owner) and the project location address shall also be placed on each bag/drum. At the end of each work shift all packaged asbestos waste shall be placed into a secured and demarked waste container.

9. Fine cleaning of residual ACM shall consist of carefully scraping and brushing using wet methods, and wet wiping the material from surfaces.

10. Air testing may be performed outside the regulated asbestos areas by the Owner’s third-party project monitor in accordance with Commonwealth of Massachusetts regulations. If fiber concentrations exceed 0.010 fibers per cubic centimeter (fibers/cc), or background levels, Work shall stop, and the Contractor shall perform clean-up activities in the affected areas and check the integrity of all critical barriers at no additional cost to Owner or General Contractor. No Work shall commence until air testing verifies that air quality levels are acceptable.

11. Clean-up activities shall include, but not be limited to, wet-wiping and vacuuming surfaces with a HEPA equipped vacuum. Work may continue only after the source of contamination is identified, corrected, and proper cleaning activities are implemented.

12. After brushing, scraping, vacuuming, and wet wiping surfaces shall be free of visible debris and fibers. A final wipe-down of the substrate with wet, lint-free cloths shall take place in order to ensure proper cleaning. All surfaces shall also be HEPA vacuumed clean.

13. After the substrate has been cleaned and all polyethylene barriers of the Work area are cleaned of all visible debris, the Contractor shall request a visual inspection of the Work area by the Owner’s third-party project monitor. The removal substrate must be clean and bare, and the entire Work area must be free and clear of any suspect material for the Contractor to pass this visual inspection.





C. Removal of Critical Barriers

1. No critical barrier shall be taken down until the final visual inspection is in

compliance.

2. After a successful final visual inspection by the Owner’s third-party project monitor and a successful clearance visual inspection, as applicable, the Contractor shall conduct the post abatement takedown.

Dear Customer:

Enclosed are asbestos analysis results for PLM Bulk samples received at our laboratory onMay 20, 2016. The samples were analyzed for asbestos using polarizing light microscopy(PLM) per the EPA 600 Method.

Sample results containing >1% asbestos are considered asbestos-containing materials(ACMs) per EPA regulatory requirements. The detection limit for the EPA 600 Method is <1%asbestos by weight as determined by visual estimation.

Thank you for your business and we look forward to continuing good relations. If you have anyquestions, please feel free to call our office at 919-481-1413.

Due to the limitations of the EPA 600 method, nonfriable organically bound materials (NOBs) such asvinyl floor tiles can be difficult to analyze via polarized light microscopy (PLM). EPA recommends thatall NOBs analyzed by PLM, and found not to contain asbestos, be further analyzed by TransmissionElectron Microscopy (TEM). Please note that PLM analysis of dust and soil samples for asbestos is notcovered under NVLAP accreditation.
