Opal provided waste removal services for a defunct Georgia-Pacific Gypsum Corporation wallboard plant in Florence, Colorado. The work consisted of:
A prior hazardous materials survey identified the presence of friable asbestos within the lower 30-foot section of the middle pipe and along the entire length of the northernmost water line. Work was performed in accordance with the Colorado Department of Public Health and Environment’s (CDPHE’s) Regulation No. 8 Control of Hazardous Air Pollutants 5CCR 1001-10. The project was particularly complex because the water lines were located on steep slopes adjacent to the main plant building. A variance was issued by the CDPHE approving an alternate procedure for asbestos removal, rather than typically encapsulating the pipes on the steep slope in negative-pressure tents. The alternate procedure included continuous plastic wrap sealing of the asbestos covered pipes, removal and end-sealing of an approximate two-foot long section of asbestos at approximate 18 to 20-foot long intervals on each line using glove bags and smoke testing to ensure a tight seal, torch cutting of the pipe sections, and crane removal of the sealed pipe sections into double-lined containers for off-site disposal at an approved facility. During the asbestos abatement, asbestos materials that were found below the pipes from previous insulation removal activities were collected along with surrounding soils, bagged and disposed as friable asbestos materials along with the pipe sections.
