Hemlock Well Inactivation Water Supply Permit Amendment

The Hemlock Well Inactivation Water Supply Permit Amendment project, overseen by the State Water Resources Control Board Division of Drinking Water, involves changing the status of the Hemlock Well from standby to inactive. Located at 5640 Hemlock Street in Sacramento, California, the scope of work requires excavating to the connection point and physically disconnecting the well from the distribution system. This project is classified under NAICS code 237110 and was issued as a domestic water supply permit amendment on June 17, 2026. The project is designated as a minor modification to an existing public water system with no change in use. Consequently, it is categorized as exempt under Class 1: Existing Facilities per California Code of Regulations section 15301, meaning no exceptions to the CEQA Guidelines apply. Primary points of contact for the project include Environmental Scientist Adrian Dela Calzada and Water Quality Manager Vanessa Arroyo.
