SUMMARY EXPLANATION AND BACKGROUND:

 

1.  The Utilities Department Wastewater Treatment Plant (WWTP) requires the use of sodium hydroxide (NaOH) as part of the treatment process for odor control. The WWTP East Scrubber uses NaOH 50% concentration by weight while the WWTP Central Air Scrubber uses NaOH 25% by weight.

 

2.  On March 6, 2024, City Commission approved the purchase of NaOH 25% concentration from Brenntag Mid-South, Inc., utilizing pricing from the Pinellas County agreement, Bid No. ITB # 23-0392 for an estimated amount not to exceed $61,720.

 

3.  On April 16, 2025, the Contracts Database report listed the caustic soda agreement as a non-renewal because the awarded vendor, Brenntag Mid-South, Inc., chose not to renew its contract with the City. Brenntag’s decision was based on the fact that the City did not purchase any caustic soda during the original contract term.

 

During that term, both scrubbers at the Wastewater Treatment Plant (WWTP) were inoperable, so caustic soda was not required for odor control. Now that the scrubbers are operational again, caustic soda is once more necessary for proper operation.

 

4.  Pinellas County renewed its agreement (ITB #23-0392) with Brenntag Mid-South, Inc. for an additional 24 months, extending the term from July 17, 2025, through July 17, 2027. Under the terms of the contract, Brenntag Mid-South, Inc. is eligible to request an annual CPI-based price adjustment; however, the vendor has opted to maintain its original contract rates, as shown below.

5.  The Central Air Scrubber, which uses NaOH 25%, has a 6,700-gallon holding tank and can accept bulk tanker loads.  The annual estimated usage for NaOH 25% is 18,000 gallons at the bulk delivery rate of $1.22. The estimated annual cost is $21,960.

 

6.  The City’s East Scrubber, which uses NaOH 50%, has a 900-gallon holding tank and can only accept non-bulk deliveries. The annual estimated usage for NaOH 50% is 8,000 gallons at the non-bulk delivery rate of $3.14, equating to an estimated annual cost of $25,120.

 

7.  Staff recommends City Commission’s authorization of the purchase of sodium hydroxide 25% and 50% by weight on an as-needed basis from Brenntag Mid-South, Inc. utilizing the Pinellas County agreement bid #23-0392-ITB for an annual amount not to exceed $47,080, pursuant to Section 35.18(C)(5) of the City's Code of Ordinances.
