Asbestos Control Options for Schools 1979 Environmental Protection Agency EPA

The four approaches for controlling asbestos exposure are an Operations & Maintenance Program - a program of training, cleaning, work practices, and periodic surveillance to maintain the asbestos in good condition, ensure clean-up of asbestos fibers previously released, and prevent further release by minimizing and controlling asbestos disturbance; Repair - returning damaged asbestos to an undamaged condition or to an intact state through limited replacement and patching' Encapsulation - treating asbestos with a liquid that, after proper application, surrounds or embeds asbestos fibers in an adhesive matrix to prevent fiber release. The material may be a penetrant, which adds cohesion by penetrating the asbestos material, or a bridging encapsulant, which covers the surface of the material using airless spray equipment at low pressure in order to reduce fiber release during applications. Enclosure - an airtight (or as close to air tight as is possible to construct) barrier installed between the friable asbestos and the building environment. They are typically constructed by mechanical attachment or spray application. For example, materials such as PVC or corrugated metal may be fastened around insulated piping or a barrier may be constructed around asbestos fireproofing on structural members by spraying material that cures into a hard shell; and Removal - stripping asbestos from its substrate. Asbestos material is separated from the underlying surface, collected, and placed in containers for burial in an approved disposal site. This is clipped from the March 16, 1979 EPA press conference by Administrator Doug Costle introducing the EPA's Asbestos in schools campaign that included technical guidance packets; toll free assistance number; & seminars offered to combat the exposure to hazardous asbestos present for school age children. In 1979, under the Toxic Substances Control Act (TSCA), EPA began an asbestos technical assistance program for building owners, environmental groups, contractors and industry. In May 1982, EPA issued the first regulation intended to control asbestos in schools under the authority of TSCA; this regulation was known as the Asbestos-in-Schools Rule. Starting in 1985, loans and grants have been given each year to aid Local Education Agencies (LEAs) in conducting asbestos abatement projects under the Asbestos School Hazard Abatement Act (ASHAA). In 1986, the Asbestos Hazard Emergency Response Act (AHERA; Asbestos Containing Materials in Schools, was signed into law by then President Reagan. AHERA is more inclusive than the May 1982 Asbestos-in-Schools Rule. AHERA requires LEAs to inspect their schools for asbestos containing building materials (ACBM) and prepare management plans which recommend the best way to reduce the asbestos hazard. Options include repairing damaged ACM, spraying it with sealants, enclosing it, removing it, or keeping it in good condition so that it does not release fibers. The plans must be developed by accredited management planners and approved by the State. LEAs must notify parent, teacher and employer organizations of the plans, and then the plans must be implemented. AHERA also requires accreditation of abatement designers, contractor supervisors and workers, building inspectors, and school management plan writers. Those responsible for enforcing AHERA have concentrated on educating LEAs, in an effort to ensure that they comply with the regulations. Contractors that improperly remove asbestos from schools can be liable under both AHERA and NESHAP. Doug Costle was EPA Administrator under President Carter from March 1977 to January 1981.

ADAO seeks to give asbestos victims and concerned citizens a united voice to raise public awareness about the dangers of asbestos exposure. ADAO is an independent global organization dedicated to preventing asbestos-related diseases through education, advocacy and community. ADAO's mission includes supporting global advocacy and advancing asbestos awareness, prevention, early detection, treatment, and resources for asbestos-related disease.
