Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES General Estimated losses from loss contingencies are accrued by a charge to income when information is available prior to the issuance of the financial statements that indicates it is probable that a liability could be incurred, and the amount of the loss can be reasonably estimated. Legal expenses associated with the loss contingency are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred. Environmental matters The Company uses surety bonds to support certain environmental bonding obligations. As of December 31, 2021 and 2020, the Company had surety bonds totaling $117.0 million and $117.5 million outstanding, respectively. Other commitments and contingencies The Company is involved in legal proceedings related to its course of business. Management does not believe that these legal cases will have a material effect on the Company’s financial condition or results of the operation.
