  1. Is EPA concerned about the decon wash for trucks getting washed away in a heavy rainfall and spreading asbestos? (8-10-2009)

    There is an insignificant possibility of asbestos moving off site due to the decon wash on-site. It is important to emphasize that asbestos, being a fiber, does not readily move in soil, stone, water, etc. The likelihood of asbestos moving off site from the decon pad in amounts that would exceed the maximum contaminant level is minimal.

    The need for a Certified Industrial Hygienist is unwarranted in this case, as the predictable properties of asbestos are best understood by a geologist.

  4. What is the decontamination process and what is going to be done with the waste products generated in the decontamination process? (9-5-2008)

    The decontamination pad was constructed near the existing tennis court. It will primarily be used to wash off gravel dust from truck tires carrying equipment into or out of the site, as necessary. Decon water will be allowed to drain through the decon pad, into the ground surface. Collecting decon water is unnecessary since the only contaminant of concern is asbestos and there is no significant threat of fibers migrating through the ground surface into the ground water. A berm will be constructed around the decon pad to prevent potential migration of asbestos via surface runoff. In addition, since the trucks will be driving on the access roads constructed with clean materials the possibility of the tires getting contaminated is minimal.

    Personal protective equipment worn by the site workers may be contaminated with fibers. It is bagged at the end of the day for off-site disposal.
