Class Code: 1655
Per NCCI's Scopes Code Description:
Code 1655 contemplates surface quarries operated by lime manufacturers, provided that at least 75% of the stone quarried is used in the actual lime manufacture. If more than 25% of the quarry output is used for other than lime manufacture, such operations shall be classified under 1624—Quarry NOC.
The crushing of the limestone at the quarry site prior to processing at the plant is contemplated within this classification. Code 1655 does not apply to the production of crushed stone to produce agricultural lime. Refer to Code 1624 for this exposure.
(MA) State Addendum: Code 1655 also applies to the manufacture of lime from limestone in that it contemplates the use of kilns in which the operation of limestone burning or calcination produces lime or quicklime. Additionally, the manufacture of hydraulic lime and hydrated lime is contemplated under Code 1655.
