Title
Resolution to Approve the Purchase of High Calcium Dust Quicklime from Mintek Lime for the Wastewater Treatment Plant, Bid No. ITB-4168A ($75,000.00)
Memorandum
Your approval is requested to authorize the purchase of high calcium dust quicklime from Mintek Lime for the City's Wastewater Treatment Plant (WWTP) at an estimated cost of $75,000.00 for FY12.
The WWTP uses two varieties of high calcium quicklime, dust lime and pebble lime. Dust lime is used to help control odors from biosolids destined for disposal in a landfill. Pebble lime is slaked and added to biosolids to stabilize it for land application. High calcium quicklime is essential for the WWTP's continued compliance with state regulations.
An invitation to bid (ITB) to supply high calcium quicklime for the WWTP was initially offered in ITB-4168. There was just one respondent to the invitation. Upon review of that bid, it was determined that based on the anticipated amount of lime to be purchased, the cost would substantially exceed the WWTP's budgeted amount for the chemical.
An invitation to bid was re-offered under ITB-4168A. The following suppliers submitted bids in response to ITB-4168A:
Minteck Lime $44.80 / ton dust lime, delivered
Huron Lime, Inc. $125.00 / ton dust lime, delivered
Mintek Lime offered an alternative high calcium dust quicklime for approval that is a byproduct of another industrial process rather than a manufactured product. Staff reviewed the alternative quicklime specifications, compared it to ITB specifications and recommends that Mintek Lime be approved as the lowest responsible bidder to supply high calcium dust quicklime to the WWTP for FY12.
Additionally, it is recommended that the agreement be extended for up to three additional years at no increase in cost if the supplier and the City Administrator agree. Approval for subsequent fiscal years is subject to the availability of funding.
Mintek Lime received Contract Compliance approval from Human Resources on August 5, 2011.
Funds to finance this purchase are included in the approved FY12 WWTP Operation and Maintenance budget for the Sewage Disposal System.
