In response to a congressional request, GAO examined the legality of the Environmental Protection Agency's (EPA) proposed ozone policy, focusing on: (1) legal and other problems EPA might encounter in implementing the policy; and (2) whether the policy would correct problems associated with past ozone programs.GAO found that, under the proposed policy, EPA would: (1) extend from 3 to 5 years the d...
Management of the National Acid Precipitation Assessment Program and EPA's Proposals To Control Vehicle Refueling and Evaporative Emissions
T-RCED-88-2: Published: Oct 2, 1987. Publicly Released: Oct 2, 1987.
GAO discussed the National Acid Precipitation Assessment Program's (NAPAP) research into acid rain and the Environmental Protection Agency's (EPA) proposed action to reduce gasoline vapors from motor vehicles. GAO found that: (1) although the first NAPAP assessment's purpose was to summarize current knowledge about acid rain, it generated considerable controversy; and (2) management changes and st...

Status of EPA's Efforts To Regulate Chemical Substances as Hazardous Air Pollutants Under the Clean Air Act
RCED-85-168: Published: Sep 30, 1985. Publicly Released: Oct 8, 1985.
GAO reported on the status of EPA efforts to fulfill a commitment to make a decision regarding the need for regulation of 20 to 25 chemical substances as hazardous air pollutants.GAO noted that EPA now issues notices of intent to list or regulate specific chemicals where regulation seems warranted.
