Cal. Code Regs. tit. 23 § 3979.3
This amendment to the Water Quality Control Plan for the Santa Ana River Basin (Basin Plan) revises Chapter 5, Waste Discharge Prohibitions, Section D, "Prohibitions Applying to Groundwaters" in the Basin Plan per Resolution No. R8-2006-0024 of the Regional Water Quality Control Board, Santa Ana Region. The regulatory provisions in the Basin Plan are modified by establishing a phased waste discharge prohibition on the use of septic tank-subsurface disposal systems (septic systems) in the Quail Valley area of Riverside County. Currently, the Basin Plan has a prohibition on the use of septic systems for a number of locations within the Region. This Basin Plan amendment phases in the Quail Valley area to the list of areas where septic systems are prohibited.
The Basin Plan amendment prohibits the use of new septic systems in high density areas (sub areas four and nine) upon the effective date of the Resolution and requires all existing septic systems to connect to the sewer within one year of availability of sewers. However, it does not prohibit septic systems in areas where sewers are not feasible (low density areas).
