Turbidty Sic Total Maximum Daily Loads For The Lower Cimarron River Skeleton Creek Area Ok620910 PDF Download

"This report documents the data and assessment used to establish a TMDL for Sulphur Creek, a tributary of the Blue River. The 2008 Integrated Water Quality Assessment Report (Oklahoma Department of Environmental Quality [ODEQ] 2008) identified Sulphur Creek as impaired for turbidity. Data assessment and TMDL calculations are conducted in accordance with requirements of Section 303(d) of the CWA, Water Quality Planning and Management Regulations (40 CFR Part 130), USEPA guidance, and ODEQ guidance and procedures. ODEQ is required to submit all TMDLs to USEPA for review and approval. Once the USEPA approves a TMDL, the waterbody may be moved to Category 4a of a state's Integrated Water Quality Monitoring and Assessment Report, where it remains until compliance with water quality standards (WQS) is achieved (USEPA 2003). The purpose of this TMDL report is to establish pollutant load allocations for turbidity in impaired waterbodies, which is the first step toward restoring water quality. TMDLs determine the pollutant loading a waterbody can assimilate without exceeding the WQS for that pollutant."--Executive summary.
