NOE - Notice of Exemption
Document Description
Golden State Water Company (GSWC) proposes to destroy existing Well 3 and construct Baseline Well 6 at the Project location. The Project construction and staging will be located within existing, developed, and gated facilities. The total construction footprint of Baseline Well 6 will be approximately 200 square feet and contain the well and pump inside a small building on wheels, a pipeline to connect it to the existing system, and another small building. Depending on water quality from the new well, a small chlorination treatment system building, or electrical building may also be built adjacent to the well. If the water only requires chlorination, the chlorination system will be installed, and the well will be connected to the existing distribution system in Baseline Road. If the water needs further treatment for other contaminants, then the well will be connected to an existing transmission main across Baseline Road and conveyed to a nearby treatment plant to be treated before entering the distribution system.
