On Feb. 27, 2021, the Pennsylvania Department of Environmental Protection (PADEP) published the final revision to the technical guidance document (TGD) No. 562-4180-306, titled "Civil Penalty Assessments for Coal Mining Operations," 51 Pa.B. 1083 (Feb. 27, 2021). The previous version of the TGD was last updated in 2005. The PADEP first published draft revisions to the TGD on May 4, 2019, and subsequently re-published an updated draft on Oct. 3, 2020 because substantial changes were made in response to public comments.

The TGD sets the procedure and formula that the PADEP will generally follow in assessing penalties against coal mining operators for violations of Pennsylvania's coal mining laws and the Clean Streams Law. The revised TGD makes several significant changes to how such penalties are calculated, including new, separate procedures for assessing penalties for water quality violations and revisions to the calculation of penalties for all other violations based on the seriousness of the violation and the culpability of the operator.
