Monterey Bay Regional Desalination

Location: Monterey, CA

California American Water (CalAm) is required to replace 10,730-acre-feet / year pumped from the Carmel Valley Aquifer with a new water supply source as a result of State Water Resources Control Board Order 95-10. To accomplish this, CalAm is moving forward in the planning, permitting and engineering of a seawater desalination project called the Coastal Water Project (CWP). Michael Baker International prepared the Proponent’s Environmental Assessment (PEA), which included a comprehensive range of engineering and technical studies. The PEA included an extensive community involvement process with over 50 public meetings. Michael Baker International served as the Environmental Task Manager for the Aquifer Storage and Recovery (ASR) facilities, and the pipeline. The project includes a 10 MGD seawater desalination facility at LS Power's Moss Landing Power Plant, and over 20 miles of conveyance pipelines. Michael Baker International prepared two NEPA documents for the project for components of the project on federal (US Army) land; third party review and coordination of project-wide CEQA (EIR) and NEPA (EA) documents; and assistance with acquiring permits, land and ROW. The EA process included design and permitting for infrastructure for the pilot plant. The EA required extensive coordination with Presidio of Monterey (POM). Michael Baker International continues to provide engineering and environmental support to California American Water for CalAm’s facilities as the project moves forward through the California Public Utilities Commission (PUC) regulatory approval process, permitting, design and construction. Michael Baker International also provided seawater pilot plant program management; coordination with California Department of Public Health (CDPH) of study plans, protocols, and sampling and analysis programs for pilot plant and watershed sanitary survey programs; design, construction, and operation of a corrosion control pilot plant; coordination of water quality requirements for water to be received by Cal Am from the regional desalination plant; and modeling studies for purposes of flow and pressure integration of the desalinated water into the existing CalAm system.
