Description:

Abstract:

The Envirofacts (EF) point shapefile layer in the National Shapefile Repository provides locations of EPA-regulated facilities from the Envirofacts Oracle table LRT_EF_COVERAGE_SRC, which is located within the Locational Reference Tables (LRT) contained in the Envirofacts Oracle Database. The spatial extent for this point shapefile is the conterminous U.S., Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands.

Facility data from various EPA program system tables are loaded into the LRT_EF_COVERAGE_SRC table. Only coordinate pairs with the highest accuracy values will represent each facility. The Envirofacts point shapefile contains data from the following EPA program systems:

AFS     - Aerometric Information Retrieval System (AIRS) Facility
          Subsystem
PCS     - Permit Compliance System
TRIS    - Toxic Release Inventory System
CERCLIS - Comprehensive Environmental Response, Compensation, and
          Liability Information System
RCRIS   - Resource Conservation and Recovery Information System
BRS     - Biennial Reporting System

Purpose:

The Envirofacts point shapefile layer provides Geographic Information System (GIS) applications with a valuable data layer for base mapping of facilities regulated by EPA. Currently, EPA's EnviroMapper and other various EPA public-use web-based GIS applications utilize this data set.

Supplemental_Information:

Intended_Use_of_Data:

The Envirofacts point shapefile layer is intended to be used with Environmental Systems Research Institute, Inc. (ESRI) software-based GIS applications that require access to shapefiles containing the geographic location of EPA-regulated facilities.

Limitations_of_Data:

None. Acknowledgement of the U.S. EPA would be appreciated.

Procedures:

The Envirofacts point coverage is created by the following process:

The unique identifiers and positional information is extracted from the Oracle Spatial EF_LAYER, which is registered through ArcSDE. The data are then converted to unprojected ArcView Shapefiles using the ArcSDE utility 'sde2shp' and then inserted into the National Shapefile Repository at the county and state levels for each state.

Reviews_Applied:

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

Log files are created during the extraction of data from the EF Oracle database and conversion to Shapefiles. These files are created to monitor and verify that the processing occurred without error.

Other_Related_Data_Sets:

Records from the following Envirofacts program system tables are included in the LRT_EF_COVERAGE_SRC table located within the LRT and are used to create the Envirofacts point shapefile:

EF         ef_program_facility
AFS        afs_plant_general
CERCLIS    cer_location
RCRIS      rcr_facility
PCS        pcs_permit_facility
TRIS       tri_facility

Process_Step:

Process_Description:: The latitude/longitude attribute values that come from the program system databases may or may not be populated. Latitude/longitude values of blanks or zeros are replaced in the coverage by associating the latitude/longitude values from another program facility reporting that facility as defined by the Facility Linkage Application (FLA) linkage identifier (facility_uin). In these cases, two attribute fields (source_acrnm and source_id) in the LRT will be populated by the acronym name and the code of the EPA program system from which the latitude/longitude values were borrowed.
