Section 7417-2.0 - Total Maximum Daily Loads (TMDLs) Regulation for Blackbird Creek

Article 1. The nonpoint source nitrogen load in the entire Blackbird Creek watershed shall be reduced by 40 percent from the 2002-2003 baseline level. This shall result in a yearly-average total nitrogen load of 175.5 pounds per day.

Article 2. The nonpoint source phosphorous load in the entire Blackbird Creek watershed shall be reduced by 40 percent from the 2002-2003 baseline level. This shall result in a yearly-average total phosphorous load of 19.97 pounds per day.

Article 3. The nonpoint source enterococcus bacteria load in the entire Blackbird Creek watershed shall be reduced by 80 percent from the 2002-2003 baseline level. This shall result in a yearly-mean enterococcus bacteria load of 4.67E+10 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 Blackbird Creek.

Article 5. Implementation of this TMDLs 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.
