New Source Review
Policy and Guidance Database

EPA has issued a number of policy and guidance documents interpreting the New Source Review (NSR) and Prevention of Significant Deterioration (PSD) construction permit regulations. The database contains over 600 EPA-issued policy and guidance documents and can be searched online or by downloading the full compilation to your computer or network. You can also view an index sorted by document date, title and author for a quick link to each document in the database. For correspondence related to the Title V operating permit program, please see the Title V Policy and Guidance Database.

In addition, you might find an abstract [1,876 Kb PDF format] prepared by the Stationary Source Compliance Division useful. This compendium provides an overview of older NSR related documents, dated May, 1976, to February, 1983, in brief question and answer format. As of April, 2005, most of the documents listed in the abstract have not been scanned into the database.
