Abstract |
The Permit Compliance System (PCS) is an Environmental Protection Agency (EPA) national computerized management information system that records water-discharge permit data on more than 64,000 wastewater treatment facilities nationwide. This system automates entry, updating, and retrieval of National Pollutant Discharge Elimination System (NPDES) data and tracks permit issuance, permit limits, monitoring data, and other pertaining to facilities regulated under NPDES. The Permit Compliance System (PCS) Facility Address and Permit Information File contains primary mailing address information as well as permit number, facility type, and cognizant official for all active NPDES permitted facilities, general facility and permit events (e.g., issuance and expiration dates, type of ownership code, SIC code, and location including longitude and latitude) for all active NPDES permitted facilities for the most recent year. There are approximately 49,000 industrial facilities and 15,000 municipal facilities regulated by NPDES. This data is updated twice a year. This diskette contains only major facilities which are facilities having a design or actual flow of one million gallons per day or greater, a service population of 10,000 or greater, or a significant impact on water quality (i.e., with a potential for toxic discharge, located close to a drinking water intake, discharging into stressed receiving waters, or requiring advanced treatment). Approximately 7100 permits are issued to major facilities. Municipal and non-municipal facilities not meeting the above requirements are categorized as minor. |
