| Abstract |
This document establishes Total Maximum Daily Loads (TMDLs) that address the control of pollutants affecting dissolved oxygen levels in Georges Creek (02-14-10-04). Georges Creek is a free-flowing freshwater stream. It is a tributary of the North Branch Potomac River. The water quality goal of the TMDLs is to establish allowable Carbonaceous Biochemical Oxygen Demand (CBOD) and Nitrogenous Biochemical Oxygen Demand (NBOD) inputs at levels that will ensure the ambient dissolved oxygen standard is maintained in Georges Creek. The TMDLs were developed using a mathematical model for free-flowing streams. The model was used to determine allowable CBOD and NBOD loading resulting in the maintenance of the high receiving stream dissolved oxygen concentrations. The model was also used to investigate seasonal variations in stream conditions and to establish margins of safety that are environmentally conservative. Load allocations were determined for distributing allowable loads between point and nonpoint sources. |
