ACCRUED CLOSURE COSTS AND ARO

 

Accrued closure costs represent our estimated environmental liability to clean up our Treatment Segment 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, 2025, and 2024, were as follows:

 

Amounts in thousands      
Balance as of December 31, 2023   $ 8,130  
Accretion expense     433  
Spending     (223 )
Balance as of December 31, 2024   $ 8,340  
Accretion expense     457  
Spending     (99 )
Addition     27  
Balance as of December 31, 2025   $ 8,725  

 

As of December 31, 2025, and 2024, the current portion of the closure liabilities totaled approximately $27,000 and $50,000, respectively, which reflect closure liabilities for our EWOC facility. The spending made in each of the years 2025 and 2024 was primarily at our EWOC facility. The additional closure costs accrual added in 2025 was 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 as of December 31, 2025, and 2024 with the following activity for the years ended December 31, 2025, and 2024:

 

Amounts in thousands      
Balance as of December 31, 2023   $ 3,223  
Amortization of closure and post-closure asset     (202 )
Balance as of December 31, 2024   $ 3,021  
Amortization of closure and post-closure asset     (202 )
Addition to closure and post-closure asset     27  
Balance as of December 31, 2025   $ 2,846  

 

The addition to ARO in 2025 reflects addition to closure obligation as discussed above.
