USER NOTES:

The Envirofacts point coverage provides Geographic Information System (GIS) applications with a valuable data layer for base mapping offacilities regulated by EPA. Facility locations areused in numerous types of analysis, e.g., proximity ofpopulations to one or more facilities. Currently, EPA's Gateway/GIS subsystem, Ecological Sensitivity Targetingand Assessment Tool (ESTAT), and various EPA publicuse webbasedGIS applications utilize this data set.

FGDL QUALITY ASSURANCE STATUS:

-Set tolerances to FGDL standards.
-Reprojected from Dat83, Spheroid GRS1980, to FGDL standard projection.
-Relocated 49 points from the ocean to 1) the original lat/long coordinates (as defined in LONG_DMS and LAT_DMS), or 2) to the nearest land feature, or 3) to the point location of the facility as defined in other FGDL datasets (sewtrt, pwrplts). Each relocated point has an EDITED value of 'Y'. Original lat/long coordinates were in decimal degrees, Datum83, GRS1980. They were reprojected to Datum27, degrees/minutes/seconds.
-Dropped the following "REDEFINED" items:

   SYSTEM_ID       Unique ID from respective program system; equal to the first
                      15 characters of ID item.
   CER_FAC_ID      CERCLIS unique ID name;  equal to the first 12 characeters 
                      of the ID item.  
   HANDLER_ID      RCRIS unique ID name; equal to the first 12 characeters of 
                      the ID item.
   TRI_FACILITY_ID TRIS unique ID name; equal to 1st 15 characters of ID item.
   EF_AFS_ID       AFS unique ID name; equal to the 1st 9 characters of ID item.

   PADS_ID         Not defined; equal to the first 12 characters of ID item.
   SITE_ID         Unique ID for Envirofacts point coverage; equal to the 
                      SYSTEMCODE plus the first 15 characters of the ID item.

DATA LINEAGE SUMMARY:

Facility data from various EPA program system tables were converted into a point coverage. Only coordinate pairswith the highest accuracy values represent each facility.The Envirofacts point coverage contains data from the following EPAprogram 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
   

The latitude/longitude attribute values come from the program systemdatabases and may or may not be populated. For facilities with Latitude/longitude values ofzeros, coordinates were obtained from the EPA program systems named in COORD_SRC.
