This page provides resources for subpart FF reporters, including implementation information as well as supporting documents for relevant rulemakings.
Summary
This source category consists of both underground coal mines under development and underground mines categorized by the Mine Safety & Health Administration (MSHA) as active (where coal is currently being produced or has been produced within the previous 90 days). It includes all underground coal mines that have operational pre-mining and post-mining degasification systems. Abandoned (closed) mines, surface coal mines, and post-coal mining activities are not included in this source category.
This source category consists of the following emission points:
- Each ventilation shaft.
- Each degasification system well, including degasification systems deployed before, during, or after mining operations.
