Air Pollution: Status of Implementation and Issues of the Clean Air Act Amendments of 1990.

摘要

With reauthorization of the Clean Air Act impending, you asked us to provide information on the implementation of the first six titles of the 1990 Clean Air Act amendments. Specifically, you asked us to (1) provide information on the status of EPA's implementation of the requirements established by the 1990 amendments and (2) obtain views from state governments, local programs, industries that are regulated under the act, and environmental advocacy groups (collectively referred to as stakeholders) on the issues that have either helped or hindered the implementation of the 1990 amendments.
