Wastewater and Solid Waste Permitting
Overview 
The  Wastewater Permitting Programs regulates discharges of waste that may affect  the quality of waters of the state (surface water and groundwater). These  Programs cover a wide variety of discharges including wastewater (sewage)  treatment facilities, onsite wastewater treatment systems (OWTS, a.k.a., septic  systems), food processing industries (including wineries), municipal solid waste  (landfills), and other industries that discharge non-hazardous wastes.
National Pollutant Discharge Elimination System (NPDES)  Wastewater
       The National  Pollutant Discharge Elimination System (NPDES) program is a federal program,  which has been delegated to the State of California for implementation. NPDES  permits, also referred to as Waste Discharge Requirements, are issued to  regulate the discharge of municipal wastewater or industrial process, cleaning,  or cooling, wastewaters, commercial wastewater, treated groundwater from  cleanup projects, or other wastes to surface waters only.

       If the waste  discharge consists only of non-process storm water, it may be regulated under  the NPDES Storm  Water program. 
Onsite Wastewater Treatment Systems (OWTS) / Septic Systems
       Onsite wastewater treatment systems (OWTS) commonly known as septic  systems that primarily treat domestic wastewater and employ subsurface  disposal. On June 19, 2012,  the State Water Resources Control Board (State Water Board) adopted Resolution No. 2012-0032, adopting the Water Quality Control Policy for  Siting, Design, Operation, and Maintenance of Onsite Wastewater Treatment  Systems (OWTS Policy).

Solid Waste Land Disposal Program / Landfills 
       The Solid  Waste Land Disposal Program regulates the discharge to land of certain solid  and liquid wastes. These wastes include municipal solid waste (MSW), hazardous  wastes, designated wastes, and nonhazardous and inert solid wastes. In general,  these wastes cannot be discharged directly to the ground surface without  adversely affecting groundwater or surface water, and therefore must be  contained to isolate them from the environment.

Waste Discharge Requirements for Wastewater, Waste Residuals, & Recycled Water
       The Waste  Discharge Requirements (WDR) Program regulates all discharges of waste to  land.  Waste discharge requirements  adopted under the WDR Program protect surface water by either prohibiting  discharge of a pollutant to waters of the U.S. or prescribing requirements for  discharge to surface waters not waters of the U.S., and they protect  groundwater by prescribing waste containment, treatment, and control  requirements. The WDR program, also known as the Non-Chapter 15 Permitting,  Surveillance and Enforcement Program, is a mandated program under which WDRs  are issued to regulate the discharge of municipal, industrial, commercial and  other wastes to land.

Waste  Classification  
       Section 13260(a) of the California Water Code requires that any  person discharging waste or proposing to discharge waste within any region,  other than to a community sewer system, that could affect the quality of the  waters of the State, must file a report of waste discharge. This report must  outline the types of wastes to be discharged in order to determine appropriate  waste management unit design, operation, monitoring, closure and post closure  maintenance requirements. The first step in obtaining Waste Discharge  Requirement is determining the classification of wastes discharged to land according to risk they pose to water quality, and determine  appropriate waste management options.
