Section 7423-2.0 - Total Maximum Daily Loads (TMDLs) Regulation for Mispillion River

Article 1. The nonpoint source nitrogen load in the Mispillion River watershed shall be reduced from the 2001-2003 baseline level by 88 percent for King's Causeway Branch and 57 percent for the remaining parts of the watershed. This shall result in a yearly-average total nitrogen load of 756.5 pounds per day.

Article 2. The nonpoint source phosphorous load in the Mispillion River watershed shall be reduced from the 2001-2003 baseline level by 88 percent for King's Causeway Branch and 57 percent for the remaining parts of the watershed. This shall result in a yearly-average total phosphorous load of 13.23 pounds per day.

Article 3. The nonpoint source enterococcus bacteria load in the Mispillion River watershed shall be reduced from the 2001-2003 baseline level by 87 percent. This shall result in a yearly-mean enterococcus bacteria load of 2.92E+11 colony forming units (CFU) per day.

Article 4. Based upon water quality model runs and assuming implementation of reductions identified by Article 1 through Article 3 above, DNREC has determined that, with an adequate margin of safety, water quality standards will be met in the Mispillion River.

Article 5. Implementation of this TMDL Regulation shall be achieved through the development and implementation of a Pollution Control Strategy. The Strategy will be developed by DNREC in concert with the Tributary Action Teams, other stakeholders, and the public.
