The file contains data compiled for the Resource Conservation and Recovery Act, using the Hazardous Waste Data Management System (HWDMS) database. Notification of Regulated Waste Activity, EPA Form 8700-12 was used to collect the data. The file was updated with information compiled from the Application for a Hazardous Waste Permit-Part A, EPA form 8700-23. The data includes each facility name, EPA Identification number, addresses, owner and operator information, facility contact name and phone number. The data also indicate whether a facility is a generator, treatment/storer/disposer, and/or transporter of hazardous waste. Also included is a listing of wastes handled, taken from 40CFR Pt. 261, SIC codes, Permit Process Codes, Permit Issuance data, and non-sensitive compliance and enforcement data. Data is included for all Regions and states except for Mississippi, which has already been implemented in RCRIS. PLEASE NOTE: The computer tape product consists of two separate tape files: the Hazardous Waste Data Management System (HWDMS) database, and the Resource Conservation and Recovery Information System (RCRIS) database. RCRIS is replacing HWDMS as the official RCRA notification database. During the first year of RCRIS implementation, both systems will be operational. As a state converts to RCRIS from HWDMS, the HWDMS data for that state is archived; the current plan is to archive all data that is stored in HWDMS by the end of 1991. In order to have a complete record of all RCRA notification data, the User must have both tapes.
