Description This TMDL established wasteload allocations (WLAs) for Weaver Creek, due to not meeting state water quality standards for dissolved oxygen (DO). The DO depletion was found downstream of a sewage treatment plant. The caused was linked to the carbanaceous biochemical oxygen demand (BOD) of the sewage effluent, so a WLA was set for BOD. A WLA was also set for ammonia-nitrogen levels in the effluent, which was the cause of the oxygen depletion.
