Contracts: Chemical Purchases
File ID: 2023-00788
Location: Citywide
Recommendation: Pass a Motion awarding one-year contracts through June 30, 2024 to: 1) Chemtrade Chemicals US LLC for the purchase of aluminum sulfate in an amount not-to-exceed $600,000; 2) Thatcher Company of California, Inc. for the purchase of liquid chlorine in an amount not-to-exceed $750,000; and 3) Olin Corporation for the purchase of sodium hypochlorite in an amount not-to-exceed $300,000.

1-Description/Analysis
2-Contract: Chemtrade
3-Contract: Thatcher Company of California
4-Contract: Olin Corporation
Description/Analysis
Issue Detail: The Department of Utilities (DOU) operates two water treatment plants and various facilities for wastewater treatment. As part of the treatment process, multiple chemicals are used, including liquid chlorine, aluminum sulfate and sodium hypochlorite. DOU has an ongoing need to maintain sufficient inventory of these chemicals to ensure uninterrupted service to customers. The prices for these contracts have been bid on behalf of DOU by the Bay Area Chemical Consortium (BACC).
Policy Considerations: City Code Section 3.56.240 authorizes the City Manager, by cooperative purchasing agreements approved by the City Council, to purchase supplies through legal contracts of other governmental jurisdictions or public agencies without separate competitive bidding by the City.
Economic Impacts: None.
File ID: 2023-00788 6/27/2023 Consent Item 35.
Environmental Considerations:
California Environmental Quality Act (CEQA): The purchase and use of chemicals is an ongoing activity at the City’s water and wastewater plants. The use of these chemicals is regulated by State permit requirements. The Community Development Department, Environmental Services Manager has determined that the proposed activity is not a project pursuant to the California Environmental Quality Act (CEQA). CEQA Guidelines Section 15378 (b). The activity is a continuing administrative or maintenance activity, such as the purchase of supplies, and is not subject to CEQA. CEQA Guidelines Section 15060(c)(3).
Sustainability: Chemicals purchased under these contracts comply with Section 8 of the City’s Sustainability Master Plan as they facilitate the continued treatment and protection of the City’s drinking water.
Commission/Committee Action: Not applicable.
Rationale for Recommendation: The lowest responsible bidders and proposed contract amounts are shown in the following table. In staff’s judgment, the prices for these chemicals obtained through the BACC bid process are lower than prices the City would have been able to obtain bidding on its own.
CONTRACTOR CHEMICAL CONTRACT AMOUNT
Chemtrade Chemical US LLC Aluminum Sulfate $600,000
Thatcher Company of CA Liquid Chlorine $750,000
Olin Corporation Sodium Hypochlorite $300,000
The not-to-exceed amounts of these contracts are based on DOU’s previous experience purchasing chemicals using the BACC bidding process.
Use of this cooperative agreement is in the City’s best interest because by purchasing chemicals through the BACC, the City is able to combine its bid solicitations for these chemicals into one annual bidding process. BACC is an informal cooperative among approximately 60 public water and wastewater agencies working together to purchase chemicals which yield more competitive pricing from vendors.
Financial Considerations: Sufficient funds exist in the proposed FY2023/24 DOU Operating Budget (Funds 6005/6011) to fund the agreements. Funding in future fiscal years will be subject to availability of sufficient funds in the applicable fiscal year.
File ID: 2023-00788 6/27/2023 Consent Item 35.
There are no General Funds allocated or planned for this project.
Local Business Enterprise (LBE): The City’s LBE bid requirements do not apply because the City is using an alternative procurement process and did not conduct the bidding process.

Per Section 2.16 Method of Award
Bids may be awarded by the participating BACC agencies to the lowest, responsive, and responsible bidder meeting the specifications for bulk loads for the chemical. The lowest responsive bidder will be determined by multiplying the estimated annual quantity for each participating BACC agency by the bid price for their region, and adding up the aggregate cost to all of the participating agencies in the regions. The single bid that results in the lowest overall cost to the participating agencies as a group will be determined by BACC to be the low bid, assuming the bid is determined by BACC to be complete and in compliance with the bid requirements. BACC has the right to delete terms or options from the bid contract documents and reserves the right to reject any and all bids and to waive irregularities of said bids.

About the Standard:
NSF/ANSI Standard 60: Drinking Water Treatment Chemicals - Health Effects NSF/ANSI 60 establishes minimum health effects requirements for the chemicals, the chemical contaminants, and the impurities that are directly added to drinking water from drinking water treatment chemicals. It does not establish performance or taste and odor requirements. The standard contains requirements for chemicals that are directly added to water and are intended to be present in the finished water as well as other chemical products that are added to water but are not intended to be present in the finished water. Chemicals covered by this Standard include, but are not limited to, coagulation and flocculation chemicals, softening, precipitation, sequestering, pH adjustment, and corrosion/scale control chemicals, disinfection and oxidation chemicals, miscellaneous treatment chemicals, and miscellaneous water supply chemicals.
The testing performed to this standard is done to estimate the level of contaminants or impurities added to drinking water when the chemical is used at the "Maximum Use Level" under attestment. Prior to testing, information is obtained on the formulation and sources of supply used to manufacture the chemical. This information is then reviewed along with the minimum requirements of the standard to establish the potential contaminants of concern. A representative sample of chemical is obtained for testing. The chemical sample is prepared for analysis through specific methods established in the standard based on the type of chemical and then is analyzed for potential contaminants determined during the formulation review. The laboratory results are normalized to represent potential at-the-tap values and then compared to the "single product allowable concentration" (SPAC) established by the standard.
The product is found in compliance with the standard if the normalized value is less than or equal to the allowable concentration.
