Total Maximum Daily Load Implementation Plan

A Total Maximum Daily Load (TMDL) Implementation Plan is the county’s statement of how it will reach the pollution reduction requirements of the Total Maximum Daily Loads issued by MDE for the various pollutants and watersheds in Baltimore County.

A TMDL has two different meanings. It is the document that is produced by MDE when any Maryland waterbody is listed on the state’s 303(d) list of impaired and threatened waters. MDE must then submit the TMDL to EPA for approval. Any time a TMDL document is developed, extensive scientific study is done on the pollutant of concern in the listed waterbody. This study is done with the goal of finding the maximum load of the pollutant that the waterbody can receive and still meet Maryland’s water quality standards. It is often thought of as a “pollution diet” for the watershed. All of the studying and monitoring that is done in preparing the TMDL document boils down to a single maximum load number that will be the target for pollution reduction in the waterbody. This number is also called a TMDL. In other words, the goal of the TMDL document is to justify the TMDL number, which can be found within the TMDL document.
