Air Management Data Viewer
The Air Management Data Viewer (AMDV) is the DNR's web-based mapping application that provides information about air permitted facilities, facility emissions and air quality monitoring sites in Wisconsin. The viewer also identifies federally-designated nonattainment and Class I areas. See the tabs below for more information about the data available in the viewer.
The AMDV allows users to view multiple layers of data, which are described below.
- 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.
- 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.
- 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.
- Nonattainment areas: Identifies portions of the state that are currently not attaining a National Ambient Air Quality Standard (NAAQS), 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.
There is a suite of tools available to users of the data viewer. The desktop application has the most comprehensive tool set. The mobile application has a more simplified tool set to accommodate mobile devices. Some basic user tips are available below.
- The Welcome panel, which automatically appears when the Viewer is opened, explains some of the key tools to access the provided data.
- To open the toolbar, click on the toolbar button in the upper right corner near the search bar.
- To view the map layers click on the "Show Layers" button.
- Desktop version – click "Layers" tab on the bottom of the left side bar.
- Mobile version - click "I want to...." and select "Change visible map layers."
- To view information about a facility, follow these steps.
- Under the "Layers" menu, select AM Facilities and Air Management Facilities.
- In the toolbar, select the "Identify" button under "Basic Tools."
- Click on "Identifiable Layers" to the right of the button.
- Click on the facility symbol on the map.
- Along the left sidebar, select from the list of items at that location in the left sidebar, and you can select each one to see more information.
- After clicking on a facility from the AM Facilities layer, learn more about the permits and activities at that facility by clicking the "Air Permit Search Tool" link in the left sidebar.
- The same procedure can be followed to view information about emissions, monitors and nonattainment and Class I areas.
- The more layers you have selected, the more results are listed. For example, having the "Surface Water" layer selected can bring up small creeks and other water landmarks.
- Having a layer set at "visible scale" will reduce the number of results and allow you to more easily find what you are looking for.
