NOTE 12

ACCRUED CLOSURE COSTS AND ARO

 

Accrued closure costs represent our estimated environmental liability to clean up our fixed-based regulated facilities as required by our permits, in the event of closure. Changes to reported closure liabilities (current and long-term) for the years ended December 31, 2021 and 2020, were as follows:

 

Amounts in thousands    
Balance as of December 31, 2019  $6,041 
Accretion expense   335 
Spending   (11)
Balance as of December 31, 2020  $6,365 
Accretion expense   377 
Addition to closure liability   499 
Spending   (50)
Balance as of December 31, 2021  $7,191 

 

 

The addition to closure liabilities for 2021 reflects primarily estimated costs for decommissioning activities required to restore the leased property at our EWOC facility back to its original condition at the end of its lease term. As of December 31, 2021, current portion of the closure liabilities totaled approximately $578,000 which consists primarily of the closure liabilities for our EWOC facility.

 

The reported closure asset or ARO, is reported as a component of “Net Property and equipment” in the Consolidated Balance Sheets at December 31, 2021 and 2020 with the following activity for the years ended December 31, 2021 and 2020:

 

Amounts in thousands    
Balance as of December 31, 2019  $3,539 
Amortization of closure and post-closure asset   (191)
Balance as of December 31, 2020  $3,348 
Addition to closure and post-closure asset   478 
Amortization of closure and post-closure asset   (250)
Balance as of December 31, 2021  $3,576 

 

The addition to ARO reflects closure obligations related to our EWOC facility as discussed above.
