text: On June 13, 2002, the Environmental Protection Agency (EPA) released its Report to the President on New Source Review (NSR), a program created by the Clean Air Act Amendments of 1977 to regulate emissions from new or substantially modified factories and power plants. We have been asked whether the recommendations for NSR reform contained in EPA's 2002 Report to the President are justified by the record and consistent with the need for continued protection and improvement of air quality, Congressional intent, and benefit-cost analysis.
