The quicklime shall meet the following requirements. Failure to meet any of them will be sufficient cause for rejection.

Definition: Quicklime is the product resulting from the calcinations of limestone, shell, or equivalent. This standard covers only limes, which are composed mainly of calcium oxide.

Special limes such as dolomitic limes are not subject to the specifications contained herein.

Quicklime consists primarily of calcium oxide (CaO), and to a lesser extent magnesium oxide (MgO). Hydrated lime is a finely divided powder, which results from the hydration of quicklime with enough water to satisfy its chemical affinity.

The following definitions shall apply in this standard:

Manufacturer: The party that produces quicklime, as covered in this standard.

Purchaser: The party entering into a contract or agreement to purchase quicklime (typically from the Vendor) in accordance with this standard, in this case the CITY OF MT. PLEASANT, MICHIGAN, henceforth known as the City.

Compliance: The City requires (1) An affidavit of compliance from the manufacturer or vendor that the quicklime furnished under the purchaser's specification complies with all applicable requirements of this standard; (2) A certified analysis of the quicklime furnished by either the vendor or the manufacturer; and (3) An affidavit of compliance with AWWA B202-02 and NSF/ANSI 60/61.

Purchase of Quicklime: The purchase of quicklime shall be based on 90% available calcium oxide (CaO). If any shipment has a calcium oxide content of less than 90%, the City shall deduct a penalty of 5% of the contract price for each 1% of calcium content below 90%. In no case shall the available calcium oxide (CaO) content be less than 80%.

The quicklime provided shall be of the "quick slaking" type and shall disintegrate into a solution of finely divided particles upon addition to water. This reaction shall be evidenced by a production of heat, raising the temperature of the solution to 40o C in three minutes, and the entire slaking reaction should be complete in approximately ten minutes. Slaking of the quicklime shall not produce an objectionable amount of undissolved or insoluble material and shall not in any way interfere with the feeding machinery used to feed quicklime.

Basis for Rejection: Failure to meet the specifications of this standard shall be considered grounds for rejection of the material.

The basis of rejection shall be the following:

A. Available CaO content is less than 80 percent. This percentage represents a minimum chemical requirement.

B. Failure of the quicklime to produce more than 10o rise in temperature in three minutes.

C. The production of more than five percent insoluble material upon slaking.

D. Determination of impurities more than those specified in the section labeled

"Impurities".

Notice of Nonconformance: Notice of Nonconformance with a shipment as caused by the failure of the material to meet the specifications contained herein, shall be provided to the vendor within 15 calendar days after receipt of the shipment in question. The purchaser's results shall prevail unless the vendor notifies the purchaser, within five working days after receipt of the Notice of Nonconformance, that a retest is desired.

The results of the referee laboratory shall be accepted as final. The vendor shall pay the cost of the referee analysis if the material in question is found not to meet the specifications of this standard and by the purchaser if the material does meet the specifications.

If the material does not meet the requirements of the purchaser, the vendor shall assume full responsibility for the removal of the material from the premises of the purchaser or the point of destination unless some agreement is reached between the purchaser and the vendor that a price adjustment can be made.

Physical Requirements: The quicklime supplied shall be three quarter inch pebble lime and in no case shall it exceed the following limits: None shall be retained on a one-inch sieve and not more than 5% shall pass a one quarter inch (0.25") sieve.

Chemical Requirements: Quicklime supplied under this specification shall be freshly burned and free of carbonate solids and siliceous residue. Insoluble material shall not exceed 5% by weight upon slaking.

Impurities: The quicklime supplied under this specification shall contain no inorganic or organic material in quantities capable of producing deleterious or injurious effects on the health of people consuming water that has been properly treated with lime and/or lime products. The quicklime shall conform both to NSF/ANSI standard 60/61 and to AWWA B202-02.

Sampling Method: Samples shall be collected as per AWWA B202-02 or any applicable standard from the material being loaded into the delivery truck at the point of origin and provided to the plant operator before unloading can begin. Samples shall be collected in airtight containers.

Testing Methods: Sample collection, testing methods, and any other relevant tests shall be performed in accordance with the AWWA Standard for Quicklime, ANSI/AWWA B202-02.

The City shall accept weekday delivery between 8:00 a.m. hours and 3:00 p.m. hours, unless otherwise arranged by purchaser.

The net weight of the shipment shall not deviate from the recorded weight by more than 1.5 percent. The City may require that the vendor supply, on receipt of the shipment, a certificate of certified weight attesting to the actual weight of the shipment in question.

If the reported weight of the shipment is found to be less than the actual weight, using any of the methods described above or as agreed to by the City and the vendor, the City may accept the shipment, reject the shipment, or agree to a price adjustment accounting for the weight deficiency.

Delivery of Non-Water Treatment Grade Lime: Quicklime must be water treatment quality grade unless by special arrangement with the City.
