On September 13, 2018, the California Public Utilities Commission certified the Environmental Impact Report/Environmental Impact Statement and issued California American Water Company (Cal Am) a Certificate of Public Convenience and Necessity for the Monterey Peninsula Water Supply project. The Monterey Peninsula Water Supply Project includes constructing a new desalination plant in Marina and new transmission mains to deliver water to storage facilities in Marina, Seaside, Pacific Grove, and Castroville.
As part of the water project's implementation, Cal Am water pipelines are planned to be installed within TAMC's Monterey Branch Line rail right-of-way, from Lightfighter Drive in the City of Seaside to Merritt Street in Castroville. Cal Am requested an easement for the planned water pipelines within the TAMC rail right-of-way (web attachment 4). TAMC Board approval of the Easement Purchase Agreement (web attachment 1) and the Operations Plan and Agreement (web attachment 2) would authorize the grant to Cal Am of a 20'-25' wide permanent easement and the grant temporary construction easements to install approximately 50,000 feet of water pipelines within the 100' wide Monterey Branch Line rail right-of-way in exchange for annual payments as noted above.
Prior Environmental Analysis
The entirety of the water supply project was the subject of an extensive environmental analysis, culminating in an EIR/EIS in excess of 2,000 pages. The installation of a pipeline along portions of the Monterey Branch Line was expressly identified in the EIR/EIS, and impacts of the construction and operation of the pipeline were identified, analyzed, and mitigation measures developed. The EIR/EIS was certified as prepared in compliance with CEQA by the CPUC in September, 2018.
The Monterey Branch Line area, which is the subject of the Easement Purchase Agreement and Operations Plan and Agreement, is generally undeveloped open space. No new activity in the Monterey Branch Line has occurred since the certification of the EIS/EIR. Pursuant to CEQA, once an EIR has been certified and approved, no further analysis is required unless significant changes to the approved project or to the circumstances under which the approved project will be undertaken, are shown. No such significant changes have occurred since Project approval.
Exceptions to Design Standards
The pipeline is designed to generally run through the outer 25' of the rail right-of-way with various crossings to optimize both Cal Am operations and preserve TAMC's right-of-way for future rail service. Cal Am will install the pipeline to meet the American Railway Engineering and Maintenance-of-Way Association design standards with specific spot exceptions to avoid obstructions, which are included in this approval (web attachment 3). Agency staff reviewed the request for exceptions and concurs with all of the exceptions. Cal Am also requested approval of three underground vaults to accommodate a flow meter, pressure reducing station, and actuated valve, plus one above ground backflow device within the TAMC rail right-of-way near Nashua Road. Staff also concurs with the locations of the vaults and backflow device.
None of the proposed exceptions affect the environmental conditions of the Project or preclude TAMC from implementing rail or transit service along the Monterey Branch Line in the future. Upon completion of the pipeline construction, Cal Am operations staff will assume responsibility for all operations, maintenance and monitoring of the new water pipelines.
