Clean Air Act: EPA Should Use Available Data to Monitor the Effects of Its Revisions to the New Source Review Program

A letter report issued by the General Accounting Office with an abstract that begins "A recent Environmental Protection Agency (EPA) final rule changing the Clean Air Act's New Source Review (NSR) program--a key means to protect public health and enhance air quality--has been under scrutiny by the Congress, industry, environmental groups, state and local air quality agencies, and the courts. GAO was asked to determine the basis of EPA's conclusions that (1) the rule's economic impacts would not be significant enough to merit a detailed analysis and (2) the NSR program, prior to the rule, discouraged some energy efficiency projects. GAO, among other things, reviewed EPA's analysis of the rule and its impacts, as well as guidance from EPA and the Office of Management and Budget (OMB) on analyzing such impacts. GAO also met with industry and environmental stakeholders.
