Operation of Dominguez Station 216 Well and Treatment-Water Supply Permit Amendment (Project)

The Operation of Dominguez Station 216 Well and Treatment project is a water supply permit amendment overseen by the California State Water Resources Control Board, Division of Drinking Water. Located in Carson, California, at 21718 Alameda Street, the project focuses on the operational activation of Well 2016-02, which was originally constructed in 2022 but remained inactive due to a lack of necessary treatment capabilities. To enable the well's operation, the project includes the implementation and operation of a new chloramination treatment system at the existing Station 216 Plant. The project is classified under NAICS code 221310 and was issued a Notice of Exemption on September 4, 2025. It is categorically exempt under Class 1 for Existing Facilities, as it involves the operation of an existing well and the addition of a treatment system at an existing water utility. Administrative oversight is managed by District Engineer Bill Liang of the Division of Drinking Water, with the California Water Service Company serving as the applicant.
