Suspended Solids Limits In Runoff To Chesapeake Bay

EPA has announced plans to issue draft sediment limits as the next step in establishing the Watershed Implementation Plans (WIPs) for the Chesapeake Bay Total Maximum Daily Load (TMDL). The six States within the Bay watershed are expected to use sediment limits, along with those previously issued for nitrogen and phosphorus, as the basis for completing their WIPs This plans would also detail how States will further divide these limits among pollution sources, and what best management practices and stormwater controls will be implemented to meet water quality standards.

The first drafts of the State WIPs are due to EPA by September 1. On September 24, EPA plans to issue a draft TMDL and open a 45-day public comment period, including 18 public meetings. The final WIPs are due November 29, and EPA will establish the final Bay TMDL by December 31.

MS4 Enforcement Action In Pennsylvania

U.S. Environmental Protection Agency has sent orders to four south central Pennsylvania municipalities requiring improvements to their respective Municipal Separate Storm Sewer System (MS4) programs. Orders went to Silver Spring Township and Lower Allen Township in Cumberland County, and Wyomissing Borough and West Reading Borough in Berks County. EPA issued similar orders last April to 79 other municipalities in this south central part of the state, an area that drains to the Chesapeake Bay.

The orders require the municipalities to correct problems with their respective MS4 programs and come into compliance with their stormwater discharge permit. In order to comply with their permit, municipalities are required to develop stormwater management programs to control pollutants from entering their drainage systems, which include storm drains, pipes, and ditches, designed to collect and convey stormwater runoff.

EPA continues to perform on-the-ground MS4 inspections of municipalities throughout Pennsylvania and other mid-Atlantic states for compliance with existing MS4 permit provisions. The Pennsylvania Department of Environmental Protection (PDEP) is in the process of completing a 5-year renewal of the MS4 general permit which is scheduled to be completed in the latter half of 2011.
