Reported Effects of Underground Mining

Under the Act 54 (of 1994) amendments to Bituminous Mine Subsidence and Land Conservation Act (BMSLCA) of 1966, the Department (DEP) is required to compile data and report findings regarding the effects of underground mining on land, structures and water resources.

The Department compiles, on an ongoing basis, claims of effects from bituminous underground mining relating to land damage/subsidence, methane intrusion, structure damage, utility damage, water supply contamination and water loss, and stream impairments. With the availability of tools and applications that allow for real time data compiling and public release, the Department is publishing the data from the Bituminous Underground Mining Information System (BUMIS) in an understandable format each year beginning with the data from 2018.
