California does not have state-level regulations for sub-surface wastewater (e.g., septics) disposal. Sub-surface wastewater systems are regulated on the local level. Questions dealing with sub-surface wastewater regulations can be directed to the local county Public Health Departments. The following web site can be used to locate your county's public health department: http://www.waterboards.ca.gov/rwqcb5/adopted_orders/GeneralOrders/Winery_TankHaul_GenWDR.pdf
