Subject: Recommendation to Award a Contract for Quicklime

STAFF RECOMMENDATION
Executive Summary
This item will allow Miami-Dade Water and Sewer Department (WASD) to continue purchasing quicklime (calcium oxide, CaO), delivered in bulk by truck and railcar, to support water treatment operations at the County�s three regional water treatment plants: John E. Preston, Hialeah, and Alexander Orr, on an as-needed basis. Quicklime is a critical chemical used in the water treatment process for water softening, pH adjustment, alkalinity control, and overall process optimization to ensure compliance with applicable federal, state, and local regulatory requirements, including those established by the Florida Department of Environmental Protection (FDEP) and the United States Environmental Protection Agency (EPA).

WASD treats an average of approximately 320 million gallons of drinking water per day, with a total system treatment capacity of approximately 439 million gallons per day. WASD operates two lime kilns at the Alexander Orr and Hialeah Water Treatment Plants, which produce lime for their respective facilities. Additionally, the Hialeah kiln supplies approximately fifty percent (50%) of the lime used at the John E. Preston Water Treatment Plant. To meet the remaining demand at the John E. Preston plant and to ensure operational continuity during scheduled maintenance, equipment downtime, or unforeseen outages, WASD must procure supplemental quicklime through this contract. To support these operations, WASD requires approximately 42,000 tons of quicklime annually. This contract will ensure a reliable supply of quicklime necessary to maintain continuous treatment operations, protect public health, and support regulatory compliance.

Recommendation
It is recommended that the Board of County Commissioners (Board) approve a competitive contract award, Contract No. EVN0013501, Quicklime, to Carmeuse Lime & Stone, Inc. (Carmeuse) in the amount of $124,080,000 for a five-year term for WASD. This contract will replace Contract No. FB-01772, approved by the Board via Resolution No. R-767-21.

Background
An Invitation to Bid (ITB) was issued under full and open competition on March 9, 2026. On the closing date of March 31, 2026, the County received two (2) bids. A total of 188 vendors were notified of the solicitation. An award is being recommended to the lowest priced responsive and responsible bidder. Outreach efforts included notifying vendors identified through market research, as well as the incumbent vendor, Carmeuse. Market research determined that only two vendors in South Florida are capable of supplying the required chemical in accordance with the technical specifications. No certified Small Business Enterprise (SBE) firms were able to meet the solicitation requirements.

The resulting contract provides for the purchase and delivery of quicklime (calcium oxide, CaO) in bulk quantities by truck and rail for use in potable water treatment. Due to the specialized nature of this chemical, the product must meet stringent quality and regulatory requirements. Quicklime shall have a minimum average calcium oxide (CaO) concentration of 90 percent by weight, as determined in accordance with ASTM C25-24, Standard Test Methods for Chemical Analysis of Limestone, Quicklime, and Hydrated Lime, or the latest revision approved by ASTM International.
The product must also conform to the requirements of the American Water Works Association (AWWA) Standard B202-25, or the latest revision approved by the American National Standards Institute (ANSI/AWWA B202-25), and be certified in accordance with NSF/ANSI Standard 60 for Drinking Water Treatment Chemicals. In addition, the product must comply with the standards referenced in paragraph 62-555.320(3)(a) of the Florida Administrative Code (F.A.C.), ensuring that it is suitable for use in potable water treatment and free from contaminants that could impact County water sources. The manufacturing process shall also comply with all applicable rules promulgated by the EPA governing health effects, contaminants, and impurities. Approval of this contract is essential to ensure the continued and uninterrupted operation of WASD�s water treatment facilities, thereby protecting public health, maintaining environmental compliance, and supporting the reliable delivery of safe drinking water to County residents.

Scope
The scope of this item is countywide in nature.

Fiscal Impact/Funding Source
The fiscal impact for the five-year term is $124,080,000. The current contract is valued at $84,156,816 for a five-year and three-month term and expires on October 31, 2026. The allocation under this replacement contract is higher than the current contract due to increases in unit pricing for the quicklime. Under the current contract, unit prices are $513.14 per ton for deliveries by truck and $489.11 per ton for deliveries by rail. The proposed contract reflects updated unit prices of $596.28 per ton (truck) and $577.30 per ton (rail), consistent with current market conditions, and allows for annual price adjustment based on the applicable index allowed by the contract.

Due Diligence
Pursuant to Resolution No. R-187-12, due diligence was conducted in accordance with SPD�s Procurement Guidelines to determine vendor responsibility, including verifying corporate status and that there are no performance and compliance issues through various vendor responsibility lists and a keyword internet search. The lists that were referenced included convicted vendors, debarred vendors, delinquent contractors, suspended vendors, and federal excluded parties. There were no adverse findings relating to vendor responsibility.

Pursuant to Resolution No. R-140-15, prior to re-procurement, a comprehensive review of the scope of services was conducted to ensure the replacement contract reflects the County�s current operational needs. This review included market research, posting a draft solicitation for industry comment, and conducting meetings and drafting sessions with the user department. As a result, the scope of services was refined to enhance the quicklime specifications, including product quality requirements and guaranteed available calcium oxide (CaO) content, to ensure compliance with all applicable federal, state, and local regulations.

Pursuant to Resolution No. R-252-25, efforts were made to identify potential piggybacking opportunities prior to issuing a competitive solicitation. No comparable contracts were identified with specifications consistent with the County�s requirements for access. Accordingly, establishing a new competitively solicited contract supports increased competition and reduces operational risk to the County.

Applicability of Ordinances and Contract Measures
� The two percent User Access Program applies where permitted by funding source.
� The SBE Bid Preference and Local Preference applied.
� The Living Wage Ordinance does not apply.
