Document Description
The Calleguas Regional Salinity Management Pipeline (CRSMP) is a brine and treated wastewater conveyance pipeline designed to manage the use of high salinity groundwater and treated municipal wastewater, dispose of the brine produced by enhanced water treatment, and facilitate the development of water sources otherwise unavailable due to poor water quality. The proposed project would extend the CRSMP approximately 14 miles inland from the existing eastern terminus, enabling connections to additional dischargers in Simi Valley and unincorporated Ventura County. Discharges from these phases, as well as previously constructed phases, would intermingle and combine to create the effluent discharged through the existing ocean outfall. Dischargers connecting to Phases 3 and 4 would be subject to existing NPDES constituent limits at the outfall. Any new infrastructure needed to connect specific dischargers to the project would be subject to separate CEQA review. The majority of the pipeline would be installed via conventional open-cut trench construction methods. Trenchless construction methods would be used to cross below existing drainage channels. Trenchless construction methods would also be used to cross Somis Road, Santa Rosa Road, and busy intersections to minimize traffic impacts. Based on the conclusions of the Initial Study, the following areas of potentially significant environmental impact are anticipated to require analysis in the Draft SEIR: Biological Resources, Cultural Resources, Geology/Soils (Paleontological Resources), Noise, Transportation, and Tribal Cultural Resources.
