NOTICE OF PUBLIC HEARING

concerning TENTATIVE ORDER

WASTE DISCHARGE REQUIREMENTS ORDER R5-2022-XXXX NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMIT CA0079651

FOR

LINDA COUNTY WATER DISTRICT WASTEWATER TREATMENT PLANT YUBA COUNTY AND SUTTER COUNTY

Discharger and Tentative Order Information

The Discharger provides sewerage service to wastewater customers for the community of Linda, portions of unincorporated Yuba County south of Marysville, and the City of Marysville. The City of Marysville wastewater conveyance to the WWTP began in November 2019. Wastewater primarily consists of domestic residential connections with limited commercial customers. No industrial uses occur within the current service area. The current design average dry weather flow capacity of the Facility is 5.0 million gallons per day. The Discharger is planning a regionalization project with the City of Marysville to accommodate planned and approved growth within the service area. The Discharger anticipates that the current permitted discharger rate is adequate for the service area needs through the next permit term with a current average dry weather flowrate of 2.6 million gallons per day.

The tentative Order includes new or revised effluent limitations for ammonia, biochemical oxygen demand, pH, and total suspended solids. The tentative Order proposes to maintain the human health mixing zones and dilution credits for development of the effluent limitations for chlorodibromomethane and dichlorobromomethane. The tentative Order removes effluent limits for flow because it is not a contaminant and bis (2-ethylhexyl) phthalate because it does not exhibit reasonable potential to exceed its respective water quality objective. Removal of these limits will not result in an increase in the pollutants or in the degradation of the receiving water. The tentative Order also grants an Instream Waste Concentration of 8.3% for chronic toxicity based on establishment of a 11:1 dilution ratio chronic mixing zone.
