§820.402. Closure Cost Estimate

a)         A written estimate of the cost to complete closure under Section 820.305 for the maximum amount of GCDD that will be accumulated at the GCDD recovery facility at any time must be submitted to the Agency for approval as part of each permit application. 

 

b)         The cost estimate must include all costs for all activities necessary to complete closure in compliance with Section 820.305.

 

c)         Before making or having made any change at the GCDD recovery facility that would increase the closure cost estimate, the owner or operator must revise the cost estimate and submit the revised closure cost estimate as a permit application to the Agency.  The Agency’s issuance of the permit with the revised cost estimate constitutes approval of the cost estimate.

 

d)         By January 1, 2024, and every January 1 after, the owner or operator of a GCDD recovery facility must certify to the Agency on Agency forms that the most recent approved cost estimate has not increased.
