Information about changes to Waste Site Cleanup Release Tracking Numbers
Web page

This database contains the Release Tracking Number (RTN), address and status of all regulated Waste Site Cleanup notifications: over 33,000 records. This includes the same information that is available to search on-line, as well some additional site data, in a collection of five linked files (in DBase IV format):

release.dbf - Primary release info
actions.dbf - Actions that occurred against releases
chemical.dbf - Chemicals that were released
location.dbf - Location type for a release
source.dbf - Sources of the release

If you are not comfortable using decompression and database software, we recommend that you use the Searchable Sites Database instead.

Pre-1993 Spills Database

Archived Spills Database
The Spills Database was the release notification tracking system for spills that occurred prior to October 1, 1993. This information should be considered to be primarily of historical interest since all of the listed spills have either been cleaned up or assigned new tracking numbers and moved to the databases described above. Note that these files are considered a permanent version of the Spills Database and are unlikely to be updated.
The files have been compressed using PKZIP and need to be decompressed using PKWARE or similar programs.
