California American Water Company Monterey Operation of Begonia Well 3 Water Supply Permit Amendment

The California American Water Company seeks approval to operate Begonia Well 3, a newly constructed water supply well in Monterey County that replaces an existing well within its system. The proposal is submitted as an amendment to the water supply permit under the jurisdiction of the State Water Resources Control Board, with the well site located in California and subject to local regulatory oversight. The well was constructed under a permit issued by Monterey County, and the amendment seeks formal recognition and authorization for its integration into the company’s water supply network to maintain service reliability and compliance with state standards. Key contacts for this permit amendment include Jonathan Weininger, District Engineer at the State Water Resources Control Board, who serves as the primary point of contact for regulatory review, and Spencer Vartanian, Director of Operations for California American Water Company, representing the applicant’s operational perspective. Roger Van Horn from Monterey County’s Drinking Water Protection Program also plays a critical role in local permitting and well compliance. The request was posted on July 31, 2026, and additional details can be accessed through the California Environmental Quality Act network portal, reflecting the procedural and environmental review process required for such water infrastructure changes.
