Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) Sites Version Date ------------------------------------------------------------ Identification Information Data Layer Name: Comprehensive Environment Response, Compensation and Liability Information System (CERCLIS) data for PA, MD, DE, DC, VA, and WV Description: This data layer includes point and attribute data for 4,709 CERCLIS sites within EPA Region 3 (PA, MD, DE, DC, VA, WV). This Region 3 data layer consists of a single coverage and a related data file. Site name, EPA Region, state, county, zip code, physical site classification, National Priority List status, and CERCLIS latitude and longitude source include attribute information contained within this data layer. This selected data was obtained from the CERCLIS database which contains the official inventory of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) sites. The database was designed to support EPA personnel with site, program and project management. Keywords: CERCLIS, superfund, sites, npl Citation: none File Format: The data layer is in one Arc/Info point coverage and is available in compressed Arc/Info export format. Use Restrictions: Data set must be cited when used.

An ARC/INFO point coverage was generated using CERCLIS identification numbers and corresponding site latitude and longitude data. Two additional items were added to the coverage point attribute table (PAT) to represent each coordinate in degrees, minutes, seconds format. An item representing an unique identifier number used to relate the point coverage to additional data files was also added. 2. An ARC/INFO data file was created to contain coordinate/site specific attribute information. Items contained within this data file are described in the following section. ------------------------------------------------------------ Entity/Attribute Information ITEM DESCRIPTION NAME: facility name COUNTY: county name STATE: state name FIPS: state and county code STATUS: status of CERCLIS site; 'F' is NPL site and 'N' is CERCLIS site.
