SUBJECT: WRITTEN DETERMINATION TO ENTER INTO A CONTRACT WITH UNIVAR
SOLUTIONS TO PROVIDE POTASSIUM PERMANGANATE PURSUANT TO NAPA MUNICIPAL CODE SECTION 2.91.050
P
er NMC 2.91.050, the City may enter into a contract for a "specialty item," provided that the City Manager makes a written determination of the following:
1. The project need which the City intends to satisfy through the contract for the specialty item.
The City requires chemicals that are critical to the water treatment process to ensure public health and meet all drinking water regulations and ensure a reliable treatment process. The City uses potassium permanganate at the Hennessey Water Treatment Plant process to treat the raw water as it heads towards the treatment facility. This chemical is used for oxidizing the raw water which facilitates the effectiveness of the other chemicals in the treatment process.
2. The types of property or service which are available (or used by other similarly situated private or public agencies) to meet this need (or similar needs), and the contractors which are available to provide the property or service.
Carus Chemical is the only United States manufacturer of potassium permanganate. There are no other United States suppliers for this chemical.
India and China both manufacture this product, but China is not allowed to import this chemical and India’s product would be cost prohibitive if it were available for use in the U.S.

3. The rea
sons why it is impracticable for a similar service to meet the City’s needs (inc
luding considerations of compatibility with other City services regarding ma
intenance, repair, training, quality, price, or similar consider
ations); or why the City’s needs can only be met by one unique or pro
prietary type of service (the specialty item).
The City has utilized potassium permanganate now for over 25 years in the Henne
ssey Treatment Plant processes. Carus Chemical supplied the equipment to the
City for dosing this chemical into the raw water and Univar Solutions is Carus Chem
ical’s west coast distributor of the specific dry product needed.
4. By entering into a contract for the specialty item from the proposed cont
ractor, the City will meet the purpose and goals identified in NM
C Section 2.91.010.
City Staff researched to confirm that Univar Solutions continues to be the sole distributor to our North Bay region. Hawkins, a potential distributor in Southern California was contacted, but determined shipping costs would be cost prohibitive. For the reasons stated above, entering into a purchase contract wit
h Univar Solutions will ensure the City will meet the purpose and goals of NMC Section 2.91.010.
5. The contract complies with the requirements of NMC Section
2.9 1.030 (B).
Pursuant to NMC Section 2.91.030(B)(2), (a) will be approved as to form by the City Attorney, (b) as determined by the City Auditor, there are sufficient unencumbered funds to cover the cost of the contract, and (c) upon approval by the City Council of the recommended action for the meeting of October 4, 2022, the City Council will have delegated authority to the City Manager’s designee, the Utilities Director, to approve the proposed purchase contract.
