Dewatering Centrifuge Diverter Gate Improvements at Plant No. 1, Project No. FR1-0018

The Dewatering Centrifuge Diverter Gate Improvements at Plant No. 1, Project No. FR1-0018, is a forecast project managed by the Orange County Sanitation District. The scope of work involves modifying three dewatering centrifuge diverter gates currently positioned horizontally on cake chute assemblies. These will be replaced with three new sloped diverter gates specifically designed to hold slop and liquids. The project is located at 10844 Ellis Ave, near Ward Street, in Fountain Valley, California. The project is classified under NAICS code 237990 and is designated as exempt from CEQA under Class 1 categorical exemptions, as the modifications are considered minor alterations that do not involve an expansion of use. Andrew Brown, Engineering Supervisor, serves as the primary point of contact and lead agency representative. The project was formally noted in a Notice of Exemption dated September 9, 2025.
