Chesapeake Bay and Local Waterway Restoration

The Federal Clean Water Act (CWA) was put in place to ensure chemical, physical, and biological integrity of the Nation’s waters. It established requirements for each State to develop programs to address water pollution including: establishment of water quality standards; implementation of water quality monitoring programs; identification and reporting of impaired waters; and establishment of Total Maximum Daily Loads (TMDLs), a tool that sets pollution limits necessary to maintain applicable water quality standards. development of maximum pollutant loads (wasteload allocations) that maintain water quality standards, called Total Maximum Daily Load (TMDL) documents. One means for the EPA to enforce these standards is through the National Pollutant Discharge Elimination System program (NPDES), which regulates discharges from point sources. The Maryland Department of the Environment (MDE) is delegated authority to issue NPDES discharge permits within Maryland. SHA is covered under a Municipal Separate Storm Sewer System (MS4) permit.

SHA MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4) DISCHARGE PERMIT
The MS4 permit requires SHA to adhere to Maryland water quality standards for discharges from SHA storm drain systems within urbanized counties in Maryland (Anne Arundel, Baltimore, Carroll, Cecil, Charles, Frederick, Harford, Howard, Montgomery, Prince George’s and Washington).  It includes a requirement to put practices in place that restore water quality impacts from past roadway construction and meet waste load allocations in TMDLs.  SHA’s recent focus has been on the Chesapeake Bay TMDL, issued in December 2010.  TMDLs exist for local waters that also must be met.

SHA RESTORATION PROJECTS NEAR YOU
SHA is utilizing a number of practices to reduce nutrients, sediments, bacteria, trash and PCBs to restore the State’s local waters and the Bay.  Using the interactive map, you can find projects in your area that SHA is implementing.  These projects will ensure SHA is in compliance.  As new TMDLs are issued, new plans will be developed for implementing additional projects.

Read descriptions and view photos of the types of projects SHA is using to reduce pollutants in stormwater runoff and improve water quality in local waterways and the Bay. These practices include changing land uses, reducing pollutant loads on roadways and implementing structural controls and non-structural techniques.
