Under the California Porter-Cologne Water Quality Control Act,discharges to all waters of the State, including all wetlands and other waters of the State including, but not limited to, isolated wetlands, are subject to State regulation. For more information on the Waste Discharges to Surface Water NPDES Program and WDR processes, visit the Central Valley Water Board website at:https:/Iwww.waterboards.ca.gov/centralvalley/water issues/waste to surface wat er/ Projects involving excavation or fill activities impacting less than 0.2 acre or 400 linear feet of non-jurisdictional waters of the state and projects involving dredging activities impacting less than 50 cubic yards of non-jurisdictional waters of the state may be eligible for coverage under the State Water Resources Control Board Water Quality Order No.2004-0004-DWQ (General Order 2004-0004). For more information on the General Order 2004-0004,visit the State Water Resources Control Board website at: httos:l/www.waterboards.ca.gov/board decisions/ado ted orders/water quality/200 4/wg o/wgo2004-0004.pdf Waste Discharge Requirements—Discharges to Land Pursuant to the State Board's Onsite Wastewater Treatment Systems Policy,the regulation of the septic system may be regulated under the local agency's management program. Please note that only domestic wastewater coming from bathrooms and kitchens should be discharged to septic systems. Cannabis cultivation can generate other wastewaters such as irrigation runoff,water treatment effluent, cleaning agents, and wash waters. Discharges of these wastewaters to an on-site wastewater system such as a septic tank and leach field must obtain separate regulatory authorization, such as waste discharge requirements(WDRs), a conditional waiver of WDRs, or other permit mechanism, prior to discharge.The application to obtain WDRs or a conditional waiver of WDRs can take over a year to process and requires that you characterize the wastewater chemistry and volume. In lieu of discharging to a septic system,Water Board staff recommends that wastewaters from cannabis cultivation activities be discharged to a holding tank and then hauled by a servicing company to a community wastewater treatment plant for disposal.
