Inc. — Liquid Carbon Dioxide for Fiscal Year 2023 in an
amount not to exceed $112,500.00

STAFF REVIEW: Joseph Munder, Water Treatment Plant Superintendent SIGNAT
APPROVED BY CITY ADMINISTRATOR: Michael L. Guttman SIGNATURE
ITEM SUMMARY:
Liquid Carbon Dioxide is one of the various chemicals used at the City’s Water Treatment Plant.
Approximately 300 tons of Liquid Carbon Dioxide are used annually. Liquid Carbon Dioxide is used in
the treatment process to stabilize the water chemistry after the softening process is complete. This
process, known as Recarbonation, lowers the pH of the softened water to an acceptable level.
A Notice to Bidders was advertised in the Daily Herald on September 6, 2022, and sealed bids were
opened on September 27, 2022. No bids were received; however, MacCARB, Inc. of Elgin, Illinois, the
contracted supplier for FY 2022 did submit a proposal for a total contract price of $112,500.00.00
($375.00/ton delivered). The price represents a 200% increase from the Fiscal Year 2022 delivered
price. Per the supplier, the Carbon Dioxide market is in a high degree of flux, and they are wary of
committing to a contract price at this time. The provided proposal price is safeguarding the supplier
against the inflationary economic environment, driver shortage, etc.
Staff recommends that a contract be awarded to MacCARB, Inc. for procurement of Liquid Carbon
Dioxide, at a unit price of $375.00/ton delivered, for an amount not to exceed $112,500.00 for Fiscal Year
2022.
Adequate funds will be budgeted in the Water Fund, Water Treatment Plant Operations — Chemicals (06-
34-48-4626) to cover this expenditure.
ACTIONS PROPOSED:
Approve Resolution No. 22-R-0065 authorizing the Mayor to execute a contract with MacCARB, Inc. of
Elgin, Illinois, for the procurement of Liquid Carbon Dioxide for Fiscal Year 2023 in an amount not to
exceed $112,500.00.
COMMITTEE RECOMMENDATION:
Pending recommendation from the Infrastructure Committee at its meeting on November 3, 2022.
