Resolution No.
STOCKTON CITY COUNCIL
ADOPT A RESOLUTION AUTHORIZING CONTRACT AMENDMENT NO. 5 FOR $910,000 WITH KEMIRA WATER SOLUTIONS FOR THE PURCHASE OF FERRIC AND FERROUS CHLORIDE FOR WASTEWATER TREATMENT The Regional Wastewater Control Facility (RWCF) uses various chemicals as part of the wastewater treatment process to reduce hazardous conditions and remove specific impurities; and Ferric chloride and ferrous chloride are used to control hydrogen sulfide gas production. Elevated hydrogen sulfide levels can be dangerous and are regulated under a permit with the San Joaquin Valley Air Pollution Control District; and On March 22, 2022, by Resolution 2022-03-22-1213, the City Council authorized a $3,330,620 contract with Kemira Water Solutions, Inc. (Kemira) to purchase ferric chloride and ferrous chloride. The contract expires on December 31, 2026; and Amendments No. 1 and No. 2 were approved under the City Manager's authority to accept annual price adjustments, increase the total compensation by $125,000, and revise the contract amount for the five-year term to $3,455,620; and On September 26, 2023, the City Council approved Amendment No. 3 by Resolution 2023-09-26-1203. Amendment No. 3 accepted a chemical cost adjustment lowering the unit price for both ferric chloride and ferrous chloride. It also increased the contract cost by $2,003,771 because of the additional chemicals necessary in the activated sludge sewer treatment process. Amendment No. 3 also revised the total contract amount to $5,459,391; and Amendment No. 4 was approved under the City Manager’s authority to accept annual price adjustments. The total contract amount remained at $5,459,391; and Staff reviewed the contract and determined that additional funds are needed to purchase chemicals through June 30, 2026. Ferric chloride will be procured through the formal Bay Area Chemical Consortium bid process. Staff will request City Council approval for a new contract starting July 1, 2026; and Staff recommend that the City Council adopt a resolution to approve Amendment No. 5 with Kemira Water Solutions, Inc., adding $910,000 to the contract, and revising the total contract amount to $6,369,391; now, therefore, //
