  1. Does EPA consider the material at the BoRit Site and at the Whitpain Park friable? (8-8-2007)

    EPA's opinion is that, for the most part, we are not dealing with friable asbestos on surface soils. Most of what may be considered friable asbestos waste is buried and inaccessible unless the ground is dug into. The asbestos of concern at the Site is that which may become airborne on surface soils or through unauthorized and uncontrolled digging or excavation.

    Friable asbestos-containing material (ACM), is defined by the Asbestos National Emission Standards for Hazardous Air Pollutants regulations, as any material containing more than one percent asbestos as determined using the method specified in Appendix A, Subpart F, 40 CFR Part 763, Section 1, Polarized Light Microscopy (PLM), that, when dry, can be crumbled, pulverized or reduced to powder by hand pressure.

    Non-friable ACM is any material containing more than one percent asbestos as determined using the method specified in Appendix A, Subpart F, 40 CFR Part 763, Section 1, PLM, that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure.

    The majority of the ACM (e.g., pipes, shingles, and tiles) seen throughout the Site cannot be pulverized by hand, and therefore is not considered to be friable.

  2. What is the difference between “asbestos" and "asbestos-containing material"? (9-2006)

    Asbestos is a generic term used to describe naturally occurring fibrous minerals found in certain types of rock formations. Asbestos containing material describes man-made substances that are created by mixing or binding asbestos fibers with other materials for use in a variety of products - such as floor tile, wallboard, brake lining and thermal insulation.
