METADATA FOR COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY INFORMATION SYSTEM LOCATIONS - REGION 8
Description:
The Region 8 data are located in the ARC/INFO coverage, R8CER_PTS, which was derived from the Envirofacts point shapefile layer in the National Shapefile Repository. This Repository provides locations of EPA-regulated facilities from the Oracle table LRT_EF_COVERAGE_SRC, which is located within the Locational Reference Tables (LRT) contained in the Envirofacts (EF) Oracle Database. The spatial extent for this point coverage is the conterminous U.S., Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands. The spatial extent for Region 8 is Colorado, Utah, Wyoming, Montana, North Dakota and South Dakota. Facility data from various EPA program system tables were loaded into the LRT_EF_COVERAGE_SRC table. Only coordinate pairs with the highest accuracy values will represent each facility. The Envirofacts point coverage contains data from the following EPA program systems: AIRS/AFS - Aerometric Information Retrieval System (AIRS) Facility Subsystem, BRS - Biennial Reports System, CERCLIS - Comprehensive Environmental Response, Compensation, and Liability Information System, PCS - Permit Compliance System, RCRIS - Resource Conservation and Recovery Information System and TRIS - Toxic Release Inventory System
