Notice of Public Review and Comment Period

The federal Clean Water Act provides states the authority to clean up polluted waters and develop related plans known as TMDLs.

In accordance, the Department of Environment is sharing for public review and comment, a Draft Temperature TMDL for Gwynns Falls Watershed in Baltimore County, MD.  This TMDL establishes temperature load reductions in the Gwynns Falls Watershed in order achieve a water temperature that supports a naturally reproducing trout population (68°F/20°C).

The Draft TMDL is posted on MDE’s website at:
https://mde.maryland.gov/programs/water/TMDL/DraftTMDLforPublicComment/Pages/index.aspx. Hard copies of the Draft TMDL may be requested by calling Anna Kasko at (410) 537-3857.

A public meeting will be held upon request.
