In the nine months ended September 30, 2020, the Company increased its remedial liabilities for an inactive site by $3.3 million and increased its remedial liabilities for a Superfund site by $1.8 million due to changes in the estimates of the related liabilities. These changes in estimates were triggered by the receipts of updated regulatory approval requirements for remediation. Other than these charges, there were no significant charges (benefits) resulting from changes in estimates for remedial liabilities.
