File ID: 2024-01038 6/18/2024 Consent Item 22.

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: Aluminum Sulfate, Liquid Chlorine, Hydrofluosilicic Acid, Sodium Hydroxide, Sodium Bisulfite, 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.

The Sacramento City Code Section 4.04.020 and Council Rules of Procedure (Chapter 7, Section E.2.d) mandate that unless waived by a 2/3 vote of the City Council, all labor agreements, and all agreements greater than $1,000,000 shall be made available to the public at least ten (10) days prior to council action. This item was published for 10-day review on June 7, 2024, in compliance with the City Code.

Economic Impacts: None.

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: Per historical data, 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.

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

File ID: 2024-01038 6/18/2024 Consent Item 22.
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 Fiscal Year (FY) 2024/2025 DOU Operating Budget to fund the agreements, please see table below for more details.. Funding for future fiscal years shall be subject to funding availability in the adopted budgets for the applicable fiscal year.

There are no General Funds allocated or planned for this project.

RE: Bid 08-2024 Hydrofluosilicic Acid
Dear Jennifer,
Please be advised I was just informed that the prices we submitted on the abovementioned bid were entered as a per wet ton unit of measure instead of per gallon . Please find below the correct unit of measure pricing.

Proper conversion is: Wet ton price / 2000 = wet lb price x 10.2 ppg = per gallon price.

Lot 1 East Bay - $647/wet ton = $3.30/gallon
Lot 2 Marina Sonoma Napa - $624.00/wet ton = $3.18/gallon Lot 3 North Bay - $597.00/wet ton = $3.04/gallon
Lot 4 Sacramento - $577.00/wet ton = $2.94/gallon
Lot 5 Tri Valley - $597.00/wet ton = $3.04/gallon
Please note, the additional comments submitted with the bid for 2 locations still stand. We apologize for inconvenience and appreciate your review.

If you have any questions or require additional information, please do not hesitate to contact me.

Sincerely,

Any Concentration shown as a range is due to batch variation.

SECTION 4. FIRST AID MEASURES
General advice : Move out of dangerous area.

Consult a physician.

Show this safety data sheet to the doctor in attendance.

Do not leave the victim unattended.

If inhaled : If unconscious, place in recovery position and seek medical advice.

If symptoms persist, call a physician.

In case of skin contact : Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and with difficulty.

If on skin, rinse well with water.

If on clothes, remove clothes.

In case of eye contact : Small amounts splashed into eyes can cause irreversible tissue damage and blindness.

In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

Continue rinsing eyes during transport to hospital.

Remove contact lenses.

Protect unharmed eye.

Keep eye wide open while rinsing.

If eye irritation persists, consult a specialist.

Take victim immediately to hospital.

If swallowed : Keep respiratory tract clear.

SECTION 5. FIREFIGHTING MEASURES
Suitable extinguishing media : Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Unsuitable extinguishing
media
: High volume water jet
Specific hazards during firefighting : Do not allow run-off from fire fighting to enter drains or water courses.

Hazardous combustion products : No hazardous combustion products are known Further information : Collect contaminated fire extinguishing water separately. This must not be discharged into drains.

Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

Special protective equipment
for firefighters
: Wear self-contained breathing apparatus for firefighting if necessary.

SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures : Use personal protective equipment.

Environmental precautions : Prevent product from entering drains.

Prevent further leakage or spillage if safe to do so.

If the product contaminates rivers and lakes or drains inform respective authorities.

Methods and materials for
containment and cleaning up
: Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust).

Keep in suitable, closed containers for disposal.

SECTION 7. HANDLING AND STORAGE
