National Pollutant Discharge Elimination System (NPDES)

This layer displays the locations of regulated facilities that discharge pollutants into surface waters in the United States. Location and environmental characteristics about facilities requiring discharge permits is contained in the Environmental Protection Agency (EPA) National Pollutant Discharge Elimination System (NPDES). Facilities requiring permits include industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters (via discrete conveyances such as pipes or man-made ditches). Individual homes that are connected to a municipal system are not reported to the EPA. For more information, please visit the EPA National Pollutant Discharge Elimination System web page.

Physiographic Section Regions

This is a polygon coverage of Physiographic Divisions in the
conterminous United States. It was automated from Fenneman’s
1:7,000,000-scale map, “Physical Divisions of the United
States,” which is based on eight major 1946 divisions, 25 provinces,
and 86 sections representing distinctive areas having common
topography, rock types and structure, and geologic and
geomorphic history.

Ecoegions

Ecoregions are identified by analyzing the patterns and composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity (Omernik 1987, 1995). These phenomena include geology, landforms, soils, vegetation, climate, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another regardless of the hierarchical level. A Roman numeral classification scheme has been adopted for different hierarchical levels of ecoregions, ranging from general regions to more detailed:

Level I – 12 ecoregions in the continental U.S.
Level II – 25 ecoregions in the continental U.S.
Level III -105 ecoregions in the continental U.S.
Level IV – 967 ecoregions in the conterminous U.S.
Explanations of the methods used to define these multi-agency ecoregions are given in Omernik and Griffith (2014), Omernik (1995, 2004), and CEC (1997).
