Total maximum daily load (TMDL) Action Plans
The City’s ’stormwater permit’, also referred to as an MS4 (Municipal Separate Storm Sewer System) permit, directs that the City develop strategies / plans to address reduction of specific pollutants. The strategies are referred to as a Total Maximum Daily Load (TMDL) Action Plans. The Action Plans guide the City’s pollutant run-off reduction strategy for designated ’pollutants of concern’- nitrogen, phosphorus, sediment, and bacteria. The City has developed two Action Plans; one to address nitrogen (N), phosphorus (P), and sediment(s)- collectively referred to as the Chesapeake Bay TMDL Action Plan, Phase 2 (PDF).

The second plan is prepared to recognize a City strategy for addressing bacteria pollution (e.g. fecal coliform / e. coli bacterias). Bacteria presence is a measure of E. coli, an indicator of overall bacteria presence potentially in the waters. The presence of bacteria has been verified through water monitoring resulting in development of a state-level Rappahannock River TMDL Action Plan. The City is required to develop a Bacteria TMDL Action Plan, a Fredericksburg Bacteria TMDL Action Plan - FINAL 2020 (PDF) has been developed to document bacteria reduction efforts in stormwater runoff.
