Onsite Wastewater Treatment Systems

The Local Agency Management Program (LAMP) is the culmination of the actions required by Assembly Bill 885 (AB 885) which directed the State Water Resources Control Board (SWRCB) to develop regulations or standards for onsite wastewater treatment systems (Septic Treatment Systems) to be implemented by qualified local agencies. The SWRCB adopted the Water Quality Control Policy for Siting, Design, Operation, and Maintenance of Onsite Wastewater Treatment Systems on June 19, 2012 (OWTS Policy). The OWTS Policy allows local agencies, such as the County of San Luis Obispo, to permit and approve Septic Treatment Systems, based on a local ordinance, after approval of a LAMP by the Central Coast Regional Water Quality Control Board (Central Coast Water Board). 

The County of San Luis Obispo LAMP is designed to protect groundwater sources and surface water bodies from contamination through the proper design, placement, installation, maintenance, and assessment of individual Septic Treatment Systems. 

The LAMP develops minimum standards for the treatment and ultimate disposal of sewage though the use of Septic Treatment Systems in non-sewered unincorporated areas of San Luis Obispo County. The LAMP will also expand the ability of Planning & Building to permit and regulate alternative Septic Treatment Systems while protecting water quality and public health.
