New Source Review
Policy and Guidance Database

EPA has issued a number of policy and guidance documents that interpret the New Source Review (NSR) and Prevention of Significant Deterioration (PSD) construction permit regulations. Region 7 has developed a searchable database which contains over 550 EPA-issued policy and guidance documents. For an index of the documents currently in the database click here.

You can search the database online or download the database. Downloading the database will give you quicker searches and a more powerful search engine.

In addition to the database, we are making available abstracts (1,876 Kb PDF format), created by the Stationary Source Compliance Division, of a large number of older NSR related documents dating from May, 1976 to February, 1983 that you might find useful. As of August, 2000, most of the documents listed in this abstract file are not in our database.

Download the Database

To use the database you must have the Adobe Acrobat reader with the search plug-in installed on your computer. The Adobe Acrobat reader with the search plug-in can be downloaded from https://www.adobe.com/ and is available for many types of computers and operating systems. Also, the Region has created a similar database for title V policy and guidance documents.

The database was last revised on February 11, 2003.

There are two sets of files for the database. One set is the complete database. The other set is an update to the previous version of the database. You can install or update the database by downloading a zip file, or if you are using Windows, a self extracting executable file. If you use the zip file you will need software that can unzip the file.

Instructions for downloading entire database:

1. Download nsrpg.exe (16.5 Mb) to the directory under which the nsrp&g directory will be created. For example, if you download the file to your computer's root directory on the C: drive the path to the install database will be C:\nsrp&g.
2. Execute nsrpg.exe by double clicking on its file name in Windows Explorer or File Manager.
3. Click "Unzip" to extract the files and then close the program.
4. You may then delete nsrpg.exe from your computer.
