DISPOSITION OF BUSINESS	Dec. 31, 2023
Discontinued Operations and Disposal Groups [Abstract]
DISPOSITION OF BUSINESS	DISPOSITION OF BUSINESS On June 30, 2022, the Company completed the sale of a line of business as part of its continuous focus on divesting certain non-core operations. The divested line of business was previously included within the Environmental Sales & Service reporting unit of the Environmental Services segment. The Company determined that the disposition did not constitute a strategic shift and that the impact on the Company's overall operations and financial results was not material. Accordingly, the operations associated with the disposal were not reported in discontinued operations. The final purchase price for the line of business was $18.8 million, after settling working capital, of which $1.5 million was held in escrow, half of which was received in 2023, and the remaining amount received in early 2024. The gain on sale of $8.9 million, after accounting for the assets sold, liabilities transferred upon sale and transaction costs, was included in gain on sale of business in the Company's consolidated statement of operations for the year ended December 31, 2022.
