The Discharger indicated the receiving water temperature exceedance at RSW-002D occurred because of low flow conditions and recent snow melt causing the RSW-001U temperature to be much lower than the effluent-dominated temperature at RSW-002D. Violation B Report
1079063 04/08/2020 Order Conditions The difference between the upstream and downstream receiving water was 7*F. The limit in the WDRs is 5*F. The temperature differential exceedance was due to very low flow upstream of the Facility's discharge location. Violation B Report
