Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 17. COMMITMENTS AND CONTINGENCIES In the ordinary course of conducting its business, the Company becomes involved in litigation, administrative proceedings and governmental investigations, including environmental matters. At August 31, 2021 and 2020, the Company had $0.5 million and $0.7 million, respectively, accrued for cleanup and remediation costs at certain sites in response to statues enforced by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA"). Total accrued environmental liabilities, including CERCLA sites, were $7.1 million and $3.4 million as of August 31, 2021 and 2020, respectively, of which $2.3 million and $2.7 million were classified as other long-term liabilities as of August 31, 2021 and 2020, respectively. These amounts have not been discounted to their present values. Due to evolving remediation technology, changing regulations, possible third-party contributions, the inherent uncertainties of the estimation process and other factors, amounts accrued could vary significantly from amounts paid.
