Sodium bisulfite

The City of Ukiah, located in Mendocino County, California, is seeking bids for a one-year contract to procure approximately 15 tons of 25% Sodium Bisulfite for its Wastewater Treatment Plant (WWTP). The procurement is structured as a Request for Bid (RFB) with specific technical requirements, including compliance with A.W.W.A./ANSI Standards. Vendors must deliver the chemical in approximately 4.5-ton loads, with deliveries required within five calendar days after order receipt. The bid submission deadline is October 17, 2025, at 1:30 p.m., with both physical and email submissions accepted. The city will evaluate bids based on the lowest overall price, with a local vendor preference that allows a 5% price adjustment (up to $2,500) for vendors meeting specific Mendocino County business criteria. Bidders must possess a current City of Ukiah business license and demonstrate compliance with DOT Hazardous Materials regulations and OSHA standards.

The solicitation does not explicitly mention specific set-aside designations or restrictions for disadvantaged enterprises. Vendors must provide comprehensive insurance coverage and be prepared to indemnify the City against potential claims or damages. Certificates of insurance must be submitted within five days of contract award. While no incumbent vendors are identified, the contract specifications indicate that the city reserves the right to accept or reject any bids and is not obligated to purchase the full estimated quantity. The pricing structure requires quotes to be freight off-loaded at designated city locations, with invoices for Water Treatment Plant deliveries being non-taxable. Although a specific budget range is not disclosed, the procurement is for approximately 15 tons of Sodium Bisulfite, suggesting a moderate-scale contract value that would depend on current market pricing for the chemical.
