The Enforcement Document Retrieval System (EDRS) is a full text database for documents related to enforcement policy and procedures, administrative decisions, judicial decisions, and model/sample forms. All environmental statutes the Environmental Protection Agency (EPA) enforces are covered. These EPA enforcement related documents cover the time period from approximately 1972 to the present. Each document has been retyped in order to upload it to the mainframe so it may not be exactly like the original. Any graphics and/or extensive tables or exhibits were not uploaded from the original document. EPA uses BASIS software as its text retrieval package on their mainframe computer. Any commercially available mainframe text retrieval package can be used. Please note that the database is not indexed.
