This is a collection of questions commonly asked about the new Asbestos-Containing Materials in Schools rule, promulgated by the U.S. Environmental Protection Agency in October 1987 under the Asbestos Hazard Emergency Response Act (AHERA) of 1986. Many questions are answered directly and completely, as they are clearly addressed by provisions of the rule. Other questions, however, must be answered more generally, for the Agency's response to the question may change depending upon the specific circumstances in a particular school. Schools, of course, may also be subject to State or local asbestos management and abatement requirements, not reflected in this document. This '100 Commonly Asked Questions' document is offered as a guide to help school officials, training providers and accredited persons better understand the new AHERA schools rule.
