The EPA is accepting comments on its Draft Field-Based Methods for Developing Aquatic Life Criteria for Specific Conductivity, a document that provides guidance to states on determining appropriate levels of conductivity, an indicator of water pollution.

The agency has already determined the appropriate level of conductivity to protect aquatic ecosystems in Central Appalachia. But conductivity levels near mines are typically twice as high and can be more than 10 times as high than that limit. Conductivity pollution from mountaintop removal mines harms aquatic ecosystems, and the associated water pollution, air pollution and blasting harm nearby communities. These destructive practices will continue until the EPA steps in.

Currently, no Central Appalachian state limits the levels of conductivity coal companies can discharge from mines. EPA should finalize its methodology and then begin a rulemaking process. Without a rulemaking, it is unlikely that coal companies will ever have to limit conductivity to protect water quality or aquatic life.

Tell the EPA to finalize its methodology and begin a rulemaking process for conductivity pollution.
