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.

Data Sections

April 2021 update. This update adds the 2020 yearly data and updates data tables from 2018 and 2019. The dates for “Interim solutions” have been removed from the data sets. The reason for this change is that this interim date is periodically updated to reflect the status of the claim. Because this date is not static, calculations for “days to interim solution” do not generate a meaningful time frame. Therefore, only the final resolution date remains in the data tables. Also for this update, additional values are added to each claim including a general “description” of the problem, “depth to mining”, “mining distance”, and “RPZ” (Is the claim area within the rebuttable presumption zone?). Blank cells means that no data is present in the BUMIS database.
