Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | NOTE 15 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 at the disposal site, 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, 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 $39,000,000 and has available capacity to allow for annual inflation and other performance and surety bond requirements. At December 31, 2018, our financial assurance coverage amount under this 2003 Closure Policy totaled approximately $29,977,000. The Company has recorded $15,971,000 and $15,676,000 in sinking fund related to this policy in other long term assets on the accompanying Consolidated Balance Sheets at December 31, 2018 and 2017, respectively, which includes interest earned of $1,500,000 and $1,205,000 on the sinking fund as of December 31, 2018 and 2017, respectively. Interest income for the years ended 2018 and 2017 was approximately $295,000 and $130,000, respectively. If the Company so elects, AIG is obligated to pay the Company an amount equal to 100% of the 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. The Company also had a finite risk insurance policy dated August 2007 for our PFNWR facility with AIG (“PFNWR policy”) which provided financial assurance to the State of Washington in the event of closure of the PFNWR facility. In April 2017, the Company received final releases from state and federal regulators for the PFNWR policy which enabled the Company to cancel the PFNWR policy resulting in the release of approximately $5,951,000 (which had been recorded in other long term assets on the Company’s Consolidated Balance Sheets) on May 1, 2017 in finite sinking funds previously held by AIG as collateral for the PFNWR policy. The Company used the released finite sinking funds to pay off our revolving credit with the remaining funds used for general working capital needs. The Company acquired new bonds in the required amount of approximately $7,000,000 (“new bonds”) to replace the PFNWR policy in providing financial assurance for the PFNWR facility. Upon receipt of the $5,951,000 in finite sinking funds from AIG, the Company and its lender executed a standby letter of credit in the amount of $2,500,000 as collateral for the new bonds for the PFNWR facility. 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 December 31, 2018, the total amount of standby letters of credit outstanding totaled approximately $2,648,000 and the total amount of bonds outstanding totaled approximately $11,284,000. Operating Leases The Company leases certain facilities and equipment under non-cancelable operating leases. The following table lists future minimum rental payments at December 31, 2018 under these (in thousands):

2021 |  |  | 308 |

Total rent expense under these leases was $766,000 and $754,000 for the years ended 2018 and 2017, respectively.
