Description:
Abstract:
CERCLIS is a national computerized management information system that automates entry, updating, and retrieval of Comprehensive Environmental Response, Compensation, and Liability Information System data and tracks site and non-site specific Superfund data in support of the Comprehensive Environmental Response, Compensation, and Liability Act. It contains information on hazardous waste site assessment and remediation.

For distribution with BASINS v.2.0, the spatial attributes of the database were prepared in Arcview shape file format while selected relational attributes were prepared in Arcview DBF file format.


Purpose:

The CERCLIS database was developed as a repository for site and non-site specific Superfund data in support of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

Limitations_of_Data: Not all CERCLIS sites reported in the conterminous U.S. are included. Superfund National Priority List Sites are found in this dataset. For example, sites with no assigned locational coordinates cannot be included.

Reviews_Applied: Positional and attribute accuracy are verified by taking independent samples of the data, viewing the data using ARCEDIT, and comparing the displayed data with matching records from Envirofacts.

ARC/INFO watch files are created during the extraction of data from the EF Oracle database, the processing of the EF data into ARC/INFO point coverages, and the insertion of the point coverages into ESDLS. These files are created to monitor and verify that the processing occurred without error.

Process_Description:
The BASINS CERCLIS data layer for the conterminous U.S. was created through further processing of ESDLS spatial coverage of EPA regulated facilities and from selected CERCLIS data downloaded from the Envirofacts Oracle database. The ESDLS coverage is broken into four separate Arc/Info coverages representing the NE, SE, NW and SW quadrants of the conterminous U.S. was downloaded from <ftp://ftp.epa.gov/pub/spdata/ef> as compressed Arc/Info export (e00) files. The coverages were reprojected from Albers Conic Equal Area projection with datum NAD83 to geographic decimal degrees. They were then converted to Arcview shape files using the Arc/Info ARCSHAPE command. Using Arcview, the shape files were merged to produce a single shape file that contains the point locations of EPA regulated facilities for the entire conterminous U.S. The shape file that contains the point locations of the facilities was generated by selecting only the facilities that fall under the CERCLIS program system. Facilities that are shown to be located (e.g. based on lat-long coordinates) outside the land boundary of the conterminous U.S. were excluded. Selected attribute tables were downloaded from the Envirofacts database to supplement the attribute data that was available in the ESDLS coverage. The CER_SITE_SUMMARY table in the Envirofacts database is joined permanently with the primary attribute table of the ESDLS coverage to produce the new primary attribute table of the BASINS CERCLIS data layer. No related tables were created for this data layer.

For distribution with BASINS v2.0, the national coverage was split into a series of coverages that included the spatial extent of each of the ten U.S. EPA Regions, plus the hydrologic accounting units that crossed region boundaries. The ten regional coverages therefore overlapped at regional boundaries. The coverages were distributed in PC ARC/INFO coverage format.
