Calleguas Regional Salinity Management Pipeline Phases 3 and 4

Calleguas Regional Salinity Management Pipeline Phases 3 and 4

The proposed project consists of Phases 3 and 4 of the Calleguas Regional Salinity Management Pipeline (CRSMP). The proposed project would install an underground pipeline composed of polyvinyl chloride and high-density polyethylene materials. Phases 3 and 4 would connect additional dischargers to the CRSMP. Discharges from these phases, as well as previously constructed phases, would intermingle and combine to create the effluent discharged through the ocean outfall. Effluent would be subject to existing National Pollutant Discharge Elimination System (NPDES) constituent limits at the outfall. 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. The pipeline would cross Calleguas Creek inside an existing vacant utility cell in the deck of the Upland Road bridge. Construction work would be performed from the inside of the utility cell or at ground level on the Upland Road bridge. Pedestrian access to Calleguas Creek under the bridge may be required, but the project does not propose ground disturbance, vegetation removal, or operation of mechanical construction equipment within the Calleguas Creek bed or bank. This document analyzes the environmental impacts of Phases 3 and 4 of the CRSMP.
