ITEM SUMMARY:

Carbon Dioxide is one of the various chemicals used at the City's Water Treatment Plant. Approximately
180 tons of 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.

On November 20, 2023, the City Council approved Resolution No. 23-R-0085, entering a contract with
MacCarb, Inc. for the procurement of liquid Carbon Dioxide for Fiscal Year 2024 in the amount of
$54,000.00. Staff had made an error in estimating the amount Carbon Dioxide required for Fiscal Year
2024. Staff recommends approving Change Order No. 1 to MacCarb's original contract for the
procurement of Carbon Dioxide for Fiscal Year 2024 in the amount not to exceed $4,000.00, bringing the
total contract value to $58,000.00.

Adequate funds are available the Water Fund, Water Treatment Plant Operations - Chemicals (06-34-48-
4626) to cover this expenditure in FY2024.

ACTIONS PROPOSED:

Approve Resolution No. 24-R-0083 authorizing the Mayor to execute Change Order No. 1 with MacCarb,
Inc. of Elgin, Illinois, for the procurement of Carbon Dioxide for Fiscal Year 2024 in an amount not to
exceed $4,000.00.
