This permit is for the installation, operation and maintenance of a disposal system or part thereof, for the direct or indirect discharge of treated sewage into the waters of the State. It is applicable to private sewage treatment facilities and Publicly Owned Treatment Works (POTWs), although terms and conditions may vary by facility type. Any size sewage treatment facility may be regulated by an individual WV/NPDES Permit, but small facilities (less than or equal to50,000 GPD) should review information on the available General Permit. Owners/operators of small facilities will prefer registration under the General Permit due to its less burdensome application requirements and lower application fees.
All individual Permits contain effluent limitations that require compliance with the BOD-5-,TSS, and pH standards of the Secondary Treatment Regulations of 40 CFR 133. More stringent water quality-based effluent limitations for BOD-5 and Nitrogen may be imposed in Permits where such are required to protect the dissolved oxygen water quality standard in the receiving stream. Permits may also contain water quality based effluent limitations for Fecal Coliform, Total Residual Chlorine, Copper, Lead, Zinc, or any other toxic pollutant expected present in the discharge in amounts that could violate Water Quality Standards. Permits for POTWs may also include requirements for the control of Combined Sewer Overflows (CSOs) and Sanitary Sewer Overflows (SSOs), the control of indirect discharges to the POTW, the development and implementation of POTW Pretreatment Programs, where required, and requirements for the proper disposal or reuse of biosolids. A wasteload allocation must be otained for each permit application.
*May be required if the facility is new or is proposed.
