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.

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.
