In recent years, the National Enforcement Investigations Center (NEIC) has developed an automated process for identifying those facilities which are not complying with environmental regulations across media within a specific geographic area. Eventually, this effort expanded in scope to include the entire United States and attempted to disclose corporate noncompliance. This resulted in the development, in late 1986, of what were termed "Potential Noncompliance Profiles for all 10 Regions. Following receipt of that report, the Region IV Deputy Regional Administrator requested that the Region IV report be updated for Fiscal Year 1986. Computerized data processing is essential to a facility noncompliance identification process due to the volume of data to be examined for 10 Regions in air, water and hazardous waste. NEIC recognizes that data availability and quality from the program databases [Air - Compliance Data System (CDS), Water - Permit Compliance System (PCS), Hazardous Waste - Hazardous Waste Data Management System (HWDMS)] may vary from very good to very poor and that the quality of the report is largely a direct result of the quality and reliability of the data. Acknowledging these limitations, the purpose of the noncompliance profile is to provide a comprehensive, automated strategy using the best available technology to identify facility multi-media noncompliance.
