CRA and five other Riverkeeper organizations sued EPA on March 8, challenging EPA’s removal of most of the Chester, and all of the Chester’s creeks and streams, from the list of waters requiring development of a TMDL (total maximum daily load - commonly known as a "pollution diet") to limit pollution. In all, 53 Maryland impaired water segments were de-listed, leaving the Chesapeake Bay TMDL to be the applicable pollution limit for those waters.

The problem is, the limits included in the Bay TMDL were based on monitoring data designed to protect the main stem of the Chesapeake Bay, not the Chester River, and our years of monitoring show that the pollution in the Chester River comes from local sources, not the Bay. CRA believes that using the Bay data to set pollution limits in the Chester River will result in less protection for the Chester.
