DEP Urges Homeowners to Check Mine Maps to Eliminate Risk of Subsidence


PITTSBURGH, ALLEGHENY COUNTY (WBRE/WYOU)- The Pennsylvania Department of Environmental Protection (DEP) urges homeowners to check updated mine maps to determine if their home is at risk of a mine subsidence.

Over one million homes in Pennsylvania sit on top of abandoned mines, including many in our region.

The DEP reminds homeowner’s that mine subsidence is not covered by a standard insurance company. The DEP can administer mine subsidence insurance coverage through the commonwealth.

“If you’ve checked before and think your property is not at risk, now is the time to check again,” says John Stefanko, deputy secretary of active and abandoned mine operations.

Homeowners should visit or call 1-800-922-1678 to check if their home is over an abandoned mine or for more information on the Mine Subsidence Insurance Program.
