The Air Guard and main terminal facilities can be accessed via north Trunk Highway 53, then north on Stebner Road. Haines Road and Rice Lake Road run east of the airport. Strip-type commercial development abuts the south and some of the east boundary. The west and north sides are forested with some wetlands. The current uses are airport facility, commercial, and industrial. The National Guard also still uses some of the property. (Source: U.S. Army Corps of Engineers) « see less
3 Hazardous Sites
Below are the locations of hazardous sites associated with this military installation, according to the DOD. A site’s contamination may affect a much larger area, including public and private lands and the water supplies beneath them.
High Risk
Medium Risk
Low Risk
Risk Not Evaluated or Not Required
Response Complete
We haven't independently confirmed the location of every site. If you notice a site placed at the incorrect location, please contact us.
Not all sites in the DOD data include location information, so there may be sites listed below that are missing from the map. The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
1 Active Site
Sites where military cleanup actions are still ongoing. The risk level of a site refers to a relative risk assessment made by the DOD, which prioritizes the cleanup of sites that pose greatest threat to safety, human health, and the environment.

Contaminated Areas
Groundwater: High Risk
There is VOC contamination present in the groundwater that exceeds health risk limits. There is no use of site groundwater and there are no nearby wells. Excess risk has been calculated for potential future construction/excavation workers from inhalatio It is unlikely that there are receptors for ingestion of groundwater. Potential for inhalation of groundwater vapors for future excavation/construction workers is a concern based on 2007 RI.
Contaminants: Naphthalene 130.0 ug/L 1,3,5-Trimethylbenzene 172.0 ug/L 1,2,4-Trimethylbenzene 510.0 ug/L Trichloroethylene (TCE) 1900.0 ug/L Benzene 5200.0 ug/L
Soil: Risk Not Evaluated
The Site Investigation Report indicates that at the Cirrus Project Area (CPA), 2 surface samples exceeded the Minnesota benzo(a)pyrene (B(a)P)equivalent Soil Reference Value (SRV). There were also VOC detections in the subsurface soil. At the Lot 3 Proj The CPA property is used for the design, production and assembly of aircraft and therefore has active site workers. The area where the B(a)P detections were located is used for temporary plane storage and initial start-up and system testing operations. The L3PA property is used by the Commemorative Air Force for storage, display and restoration of vintage aircraft and miscellaneous other military artifacts. The Minnesota Air National Guard also uses a building on the property as a hangar. In each case, there is a potential that workers present at the site could be exposed to contamination at the surface. All soil detections were below risk-based levels in the 2007 RI.
2 Inactive Sites
Sites where military cleanup actions are complete, according to the DOD. Note that this status does not necessarily mean the site is no longer hazardous, as many of these sites are put under long-term monitoring or other restrictions.

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
