Summary
body
Summary: The Warren Facility produces up to 1,300 wet tons of biosolids per day. Biosolids are conveyed via a series of belt conveyors to storage silos and truck loading stations. The metal truss structures that support the conveyor belts are approximately 25 to 55 years old. In September 2023, the Board approved Phase I repairs to 19 severely corroded areas of the conveyor truss supports, which were completed in 2024. Based on a structural survey of the remaining truss support structures, it is recommended that an additional 51 severely corroded areas be rehabilitated immediately, while a design for refurbishment of the truss support structures and other truck loading station improvements is completed. Pursuant to authority previously granted by the Board, the Project will be completed utilizing the Job Order Contracting Program which relies on pre-established competitively-bid construction tasks that will accelerate project delivery and reduce administration and design costs. Staff has determined that the activities described herein are exempt or otherwise not subject to the provisions of the California Environmental Quality Act (CEQA) pursuant to California Public Resources Code Section 21084 and Title 14 of the California Code of Regulations (“CEQA Guidelines”) Section 15301. This item is consistent with the Districts’ Guiding Principles to protect financial and facility assets through prudent investment and maintenance programs; and commitment to operational excellence (protection of public health and the environment, regulatory compliance, and cost effectiveness).
