Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Matters We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see Environmental below. While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows. Environmental We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a potentially responsible party. While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our consolidated financial position, results of operations, and cash flows. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $10 million at September 30, 2022 and $11 million at December 31, 2021. Of the total accrual, the current portion is included in accrued expenses and the noncurrent portion is included in other noncurrent liabilities on the Condensed Consolidated Balance Sheets. Our more significant environmental sites include a former plant site in Louisiana and a Houston, Texas plant site. Together, the amounts accrued on a discounted basis related to these sites represented approximately $7 million of the total accrual above at September 30, 2022 and $8 million at December 31, 2021, using discount rates ranging from 3% to 9% for both periods. The aggregate undiscounted amount for these sites were $9 million at September 30, 2022 and $10 million at December 31, 2021.
