Industrial effluent discharges to receiving waters are regulated by federal and state Environmental Protection Agencies. To discharge treated effluent, industrial facilities must obtain a National Pollutant Discharge Elimination System (NPDES) permit that specifies discharge limits for specific chemical constituents. These limits depend on constituent type, receiving water flow regime and assimilative capacity, tolerance of aquatic species within the water body, background water quality, etc. The goal of the project was to determine the appropriate waste load allocations to meet the EPA guidelines for "best practicable control technology currently available" (BPT) and maintain the dissolved oxygen (DO) standard within the river during dry season, while remaining cost effective. A water quality modeling package was developed to assess the waste load assimilative capacity of the receiving water as a function of flow and temperature. The model was applied to develop tables of permissible discharges based on previous day flow and today's temperature to be submitted in support of NPDES permit application.
