In fall 1989, the initial implementation of the Asbestos Hazard Emergency Response Act of 1986 (AHERA) was evaluated. This report summarizes evaluation results presented in a two-volume final report and appendices. AHERA regulations required: (1) inspection of all elementary and secondary schools to identify any asbestos-containing building materials present; (2) preparation of an asbestos management plan for each school; (3) notification of parents and staff of the plan's availability for review; and (4) training of school maintenance and custodial workers. The evaluation study focused on buildings occupied by K-12 students; schools in the target population represent about 80 percent of all 106,000 schools in the U.S. The study employed a national statistical sample of 30 communities, in which 198 schools were visited. Specially trained inspectors thoroughly reinspected each participating school building, and findings were compared with the original AHERA inspection as presented in each schools' management plan. In-person and telephone interviews supplemented building inspections. The evaluation comprised six separate research areas: school building inspections; management plans; response actions; original AHERA inspection evaluation; notification; and maintenance and custodial worker training. Original AHERA inspectors had correctly estimated the quantity of each asbestos-containing material in 60 percent of the buildings. A glossary and numerous graphs are included. (MLH)
