Power Plants

This layer shows the location of electricity generating power-plants in the U.S., the total capacity of each plant, and the primary fuel source.

Brownfield Sites

This layer displays the locations of the Environmental Protection Agency (EPA) Assessment, Cleanup and Redevelopment Exchange System (ACRES) sites. ACRES stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on Targeted Brownfields Assessments performed by EPA Regions. A brownfield site consists of land previously used for industrial purposes or some commercial uses. The land may be contaminated by low concentrations of hazardous waste or pollution, and has the potential to be reused once it is cleaned up. For more information, please visit the EPA Brownfields and Land Revitalization website or the ACRES Information web page.

Ethanol Plants

This feature class/shapefile represents Ethanol Plants. An Ethanol Plant is a facility that uses various biomass source to produce ethanol for use as a fuel.

Air Facility System Sites

This layer displays the locations of regulated facilities that discharge air pollutants in the United States. The Air Facility System (AFS) contains compliance and permit data for stationary sources of air pollution (such as electric power plants, steel mills, factories, and universities) regulated by EPA, state and local air pollution agencies. The information in AFS is used by the states to prepare State Implementation Plans (SIPs) and to track the compliance status of point sources with various regulatory programs under Clean Air Act. For more information, please visit the EPA Air Facility System web page.

Coal Fields

This data set shows the coal fields of Alaska and the conterminous United States. Most of the material for the conterminous United States was collected from James Trumbull’s “Coal Fields of the United States, Conterminous United States” map (sheet 1, 1960). The Gulf Coast region was updated using generalized, coal-bearing geology obtained from State geologic maps. The Alaska coal fields were collected from Farrell Barnes’s “Coal Fields of the United States, Alaska” map (sheet 2, 1961).

Army Corps Leveed Areas

This layer displays United States Army Core of Engineers surveyed Leveed Areas. The USACE defines a Levee Areas as the area of a floodplain from which flood water is excluded by the levee system. For more information about USACE data, visit the National Levee Database.

Air Quality System Sites

This layer displays the locations of air quality monitoring stations in the United States. The Air Quality System (AQS) contains ambient air pollution data collected by EPA, state, Local, and tribal air pollution control agencies from thousands of monitoring stations. AQS also contains meteorological data, descriptive information about each monitoring station (including its geographic location and its operator), and data quality assurance/quality control information. For more information, please visit the EPA Air Quality System web page.

Wind Turbine Density

This layer was created using point data of Wind Turbine locations within the U.S. from USGS. Density was calculated using a circular neighborhood of 1 mile and each cell is 1 square mile in area.
