TITLE: INDUSTRIAL WASTEWATER TREATMENT FACILITY SEDIMENT REMOVAL PROJECT, CIP NO. 9368 RECOMMENDED MOTION:
A motion to approve a Resolution accepting the Industrial Wastewater Treatment Facility Sediment Removal Project CIP 9368, for maintenance and responsibility.
EXECUTIVE SUMMARY:
On June 25, 2024, City Council awarded the Industrial Wastewater Treatment Facility, Sediment Removal Project, CIP 9368 to American Process Group via Resolution No. 23030 for a contracted amount of $5,988,344.00. Construction began on October 21, 2024 with an allowance of 90 working days for project completion. American Process Group has completed sludge removal for percolation ponds 1-3 under this contract for a total amount, of $5,994,155.25. Substantial completion was issued on January 27, 2025. Staff recommends the approval of a resolution to accept the Industrial Wastewater Treatment Facility Sediment Removal Project, CIP 9368 for maintenance and responsibility.
BACKGROUND:
The City of Salinas owns and operates an Industrial Wastewater Collection and Conveyance System (IWCCS) which takes agricultural process water from 26 industry users. The wastewater is conveyed for disposal or recycling to the Industrial Waste Treatment Facility (IWTF) located south of the City, adjacent to the Salinas River.
The extreme precipitation from the 2023 winter storms resulted in elevated water levels and a breach in the Salinas River. As a result, the IWTF was inundated with flood waters in January and March 2023. This caused damage to earthen berms, levees, an overflow basin, and deposited a layer of sediment across the percolation ponds. The deposited sediment has significantly impacted the percolation capacity of the ponds which limits the ability to dispose of the industrial wastewater to the underlying soils. In response City staff entered into an agreement with Carollo Engineers to provide services including design and preparation of project bid documents, and construction management services per Resolution No. 22762.
On June 24, 2024, pursuant to Resolution No. 23030, City Council awarded the Industrial Wastewater Treatment Facility (IWTF) Sludge Removal Project, CIP 9368 to American Process Group for the sum of $5,387,979.50 and allowing 90 working days for project completion.
The IWTF Sludge Removal Project, CIP 9368 began on October 21, 2024, and in general, called for the removal and dewatering of sediment from Percolations Ponds 1-3 and hauling and proper off-site disposal of the removed sediment. Table No. 1, below, identifies the amount of sediment that was removed from each pond.

CEQA CONSIDERATION:
The City of Salinas has determined that the project is exempt from the California Environmental Quality Act (CEQA) Guidelines (Section 15301(c), Class I) because the work will be maintenance of an existing water reservoir.
Furthermore, the project does not qualify for any of the exceptions to the categorical exemptions found at CEQA Guidelines Section 15300.2 as all exceptions do not relate to the project scope of work for this project.
CALIFORNIA GOVERNMENT CODE §84308:
No. This project was advertised and competitively bid and is therefore exempt from California Government Code §84308.
STRATEGIC PLAN INITIATIVE:
The proposed project meets the City Council’s goal of Infrastructure by maintaining and improving City facilities.
DEPARTMENTAL COORDINATION:
This project was coordinated by the CIP division and the Environmental & Maintenance Services Division in the Public Works Department.
FISCAL AND SUSTAINABILITY IMPACT:
The project was completed within the approved budget. Contract amounts were paid by reallocating budget from various capital projects to CIP 9368 per Resolution No. 23030. The total construction cost was $5,994,155.25.
