Universal Citation: 7 DE Admin Code 7414-1.0
Current through Register Vol. 28, No. 3, September 1, 2024

Water quality monitoring performed by the Department of Natural Resources and Environmental Control (DNREC) has shown that the Marshyhope Creek is impaired by high levels of bacteria, elevated levels of nutrients nitrogen and phosphorous, and low dissolved oxygen, and that the designated uses are not fully supported by water quality in the stream.

Section 303(d) of the Federal Clean Water Act (CWA) requires states to develop a list (303(d) List) of waterbodies for which existing pollution control activities are not sufficient to attain applicable water quality criteria and to develop Total Maximum Daily Loads (TMDLs) for pollutants or stressors causing the impairment. A TMDL sets a limit on the amount of a pollutant that can be discharged into a waterbody and still protect water quality. TMDLs are composed of three components, including Waste Load Allocations (WLAs) for point source discharges, Load Allocations (LAs) for nonpoint sources, and a Margin of Safety (MOS).

DNREC listed Marshyhope Creek on several of the State's 303(d) Lists and proposes the following Total Maximum Daily Load regulation for nitrogen and phosphorous.
