Section 7426-2.0 - Total Maximum Daily Loads (TMDLs) Regulation for St. Jones River

Article 1. The total nitrogen load from the two point source facilities in the watershed (Dover McKee Run and Reichhold Chemicals) shall be limited to 9.2 pounds per day. The nitrogen waste load allocation for Dover McKee Run will be 7.7 pounds per day and for Reichhold Chemicals will be 1.5 pounds per day.

Article 2. The total phosphorous load from the two point source facilities in the watershed (Dover McKee Run and Reichhold Chemicals) shall be limited to 0.37 pounds per day. The phosphorous waste load allocation for Dover McKee Run will be 0.24 pounds per day and for Reichhold Chemicals will be 0.13 pounds per day.

Article 3. The enterococcus bacteria load from the two point source facilities in the watershed (Dover McKee Run and Reichhold Chemicals) shall be limited to 1.67E+09 colony forming units (CFU) per day. The enterococcus bacteria waste load allocation for Dover McKee Run will be 1.1E+09 CFU per day and for Reichhold Chemicals will be 5.7E+08 CFU per day.

Article 4. The nonpoint source nitrogen load in the entire St. Jones River watershed shall be reduced by 40 percent from the 2002-2003 baseline level. This shall result in a yearly-average total nitrogen load of 860.3 pounds per day.

Article 5. The nonpoint source phosphorous load in the entire St. Jones River watershed shall be reduced by 40 percent from the 2002-2003 baseline level. This shall result in a yearly-average total phosphorus load of 63.01 pounds per day.

Article 6. The nonpoint source enterococcus load in the entire St. Jones River watershed shall be reduced by 90 percent from the 2002-2003 baseline level. This shall result in a yearly-average enterococcus load of 1.63E+11 CFU per day.

Article 7. Based upon water quality model runs and assuming implementation of reductions identified by Article 1 through Article 6 above, DNREC has determined that, with an adequate margin of safety, water quality standards will be met in the St. Jones River.

Article 8. 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.
