National Emission Standards for Hazardous Air Pollutants: Amendments to Standards for Asbestos and Mercury (1975)

EPA amendments to its 1973 national emission standards for asbestos and mercury, signed by Acting Administrator John Quarles on October 3, 1975 and published in the Federal Register of October 14, 1975. The preamble answers comments on the October 1974 proposal. The amendments brought large renovation jobs involving friable asbestos insulation under the demolition rules, allowed local exhaust ventilation where wetting would damage equipment, and added asbestos waste disposal and inactive disposal site requirements. They also extended coverage to fabricating and to molded and wet-applied insulation. Mercury provisions and test-method changes follow.
