Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | 10. Commitments and Contingencies Hazardous Waste In connection with our waste management services, we process both hazardous and non-hazardous waste, which we transport to our own, or other, facilities for destruction or disposal. As a result of disposing of hazardous substances, in the event any cleanup is required, we could be a potentially responsible party for the costs of the cleanup notwithstanding any absence of fault on our part. Legal Matters In the normal course of conducting our business, we are involved in various litigation. We are not a party to any litigation or governmental proceeding which our management believes could result in any judgments or fines against us that would have a material adverse effect on our financial position, liquidity or results of future operations. Insurance The Company has a 25-year finite risk insurance policy entered into in June 2003 (“2003 Closure Policy”) with AIG Specialty Insurance Company (“AIG”), which provides financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure. The 2003 Closure Policy, as amended, provides for a maximum allowable coverage of $28,177,000 which includes available capacity to allow for annual inflation and other performance and surety bond requirements. Total coverage under the 2003 Closure Policy, as amended, was $19,651,000 at March 31, 2020. At March 31, 2020 and December 31, 2019, finite risk sinking funds contributed by the Company related to the 2003 Closure Policy which is included in other long term assets on the accompanying Consolidated Balance Sheets totaled $11,363,000 and $11,307,000, respectively, which included interest earned of $1,892,000 and $1,836,000 on the finite risk sinking funds as of March 31, 2020 and December 31, 2019, respectively. Interest income for the three months ended March 31, 2020 and 2019 was approximately $56,000 and $81,000, respectively. If we so elect, AIG is obligated to pay us an amount equal to 100% of the finite risk sinking fund account balance in return for complete release of liability from both us and any applicable regulatory agency using this policy as an instrument to comply with financial assurance requirements. Letter of Credits and Bonding Requirements From time to time, the Company is required to post standby letters of credit and various bonds to support contractual obligations to customers and other obligations, including facility closures. At March 31, 2020, the total amount of standby letters of credit outstanding was approximately $3,139,000 and the total amount of bonds outstanding was approximately $51,538,000.
