Commitments and Contingencies Disclosure [Abstract] |
Contingent Liabilities | Contingent Liabilities In 2012, it was determined a Company owned site in Decatur, Alabama, contained hazardous substances in the soil and groundwater as a result of historical operations prior to the Company's ownership. The Company retained an environmental consulting firm to further investigate the contamination, prepare a remediation plan, and enroll the site in the Alabama Department of Environmental Management (“ADEM") voluntary cleanup program. The remediation plan, approved by ADEM in 2018, consists of chemical injections throughout the affected area and subsequent monitoring. The injection process was completed in the first quarter of 2019 and monitoring is ongoing pending certification by ADEM. At September 30, 2021 estimated costs for future monitoring are not significant and have been fully accrued. The Company does not expect to capitalize any amounts related to the remediation plan.
