Restoration and Protection

Regulations

Maryland is trying to stop erosion and sedimentation from development-related activities. Projects that will involve disturbing soil must have an approved plan for controlling erosion and sedimentation

You can help us make these laws work by reporting erosion or sediment control problems you see. Help us clean up our waterways and save the Chesapeake Bay. Call MDE, or your local sediment control authority:

MDE and DNR work together to determine Total Maximum Daily Loads (TMDLs) and produce the "303d" list.

Total Maximum Daily Loads (TMDLs) are a requirement, found in section 303(d), of the federal Clean Water Act (CWA) that became law in 1972. The "303(d)" list, as it is historically known, is a list of a jurisdiction’s impaired surface waters.

For more information about TMDLs, see MDE's pages at: http://www.mde.state.md.us/Programs/WaterPrograms/TMDL/index.asp
