This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.
WTP's were downloaded from the EPA's PCS (Permit Compliance System) database at: <http://www.epa.gov/waterscience/ftp/basins/gis_data/>

The attributes were derived directly from the EPA PCS database. <http://www.epa.gov/waterscience/ftp/basins/gis_data/>
The locations of the WWTP's were checked against the NAIP imagery from 2005 as well as compared to Google Earth which has higher resolution imagery. Most points were not located accurately with respect to the WWTP. The points were edited to accurately reflect the location of the plants according to aerial imagery.

Data set has been visually inspected.
The dataset is topologically correct.
