Air Management Data Viewer

Map Layers

Map Layers

The AMDV allows users to view multiple layers of data, which are described below.

AM facilities

• Includes the active facilities in the Air Program's Permit Search Tool.
• Does not include closed facilities or facilities that are not designated as a major or minor source of air emissions based on U.S. Environmental Protection Agency (EPA) Class Code.
• Each facility entry provides a link to the facility's permits and additional information.
• The layer is updated on a quarterly basis to include new facilities within the database.
• Facilities without an assigned compliance inspector should contact the compliance supervisor listed for the source under the "DNR Air Contacts" tab in the Air Program's Permit Search Tool.
• For attributes that end in question marks (e.g., "PSD Source?"), "Y" indicates the facility has been designated as the specified source type and "N" indicates the facility has not been designated that source type.

Emissions

• Includes annual emissions from facilities required to report emissions to the Air Program (facilities whose emissions exceed the reporting threshold) in tons per year.
• Emissions layers are updated after inventories from the previous year have been certified, usually in June.

Monitors

• Includes the air quality monitoring sites operated by the Air Program.
• Monitor locations and attributes are based on the most recent Final Monitoring Network Plan.
• For information about current and historical data from the monitors, see Wisconsin's current air quality and Wisconsin's air quality trends.

Statewide Layers

• Nonattainment areas: Identifies portions of the state that are currently not attaining a National Ambient Air Quality Standard (NAAQS) [exit DNR], as designated by EPA. For more information about nonattainment areas in Wisconsin, visit Ozone and SO2 NAAQS implementation.
• Class I areas: Identifies EPA-designated federal and nonfederal Class I areas.
• Pending nonattainment or nonfederal Class I areas will be added to the map once finalized by EPA.
