A waste load allocation is the maximum amount of pollutants in treated wastewater that can safely be discharged into a waterbody without adversely affecting its quality. DEQ, along with the U.S. Environmental Protection Agency (EPA), has evaluated the Poteau River to develop these recommended maximum amounts that may be discharged into it with a design flow of 0.55 MGD: Year round: 30 mg/L BOD5 (5-day biochemical oxygen demand) 30 mg/L TSS (total suspended solids) The comment period will be open for 45 days. If you have any concerns regarding these proposed limits, please submit your comments in writing by the end of the workday on March 19, 2015 to: David Akakpo Water Quality Division Oklahoma Department of Environmental Quality P.O.
