Section 807.622  Cost Estimate for Post-closure Care

a)         The operator of a disposal site must have a written estimate of the annual current cost of post-closure monitoring and maintenance of the site in accordance with the applicable post-closure care regulations of this Part.  The post-closure care cost estimate is calculated by multiplying the annual cost estimate by the number of years of post-closure care required by this Part.  The post-closure care cost estimate shall be a condition of the permit.

b)         Until the Agency has issued a certificate of closure for the site, the operator must revise the post-closure care cost estimate whenever a change in the post-closure care plan increases the cost estimate.

c)         Assumptions:

1)         The post-closure cost estimate must be based on the assumption that the Agency will contract with a third party to implement the post-closure care plan;

2)         The post-closure cost estimate may not be reduced by allowance for salvage value of equipment or waste, or for resale value of land.

d)         The post-closure care cost estimate must, at a minimum, include the following elements if required in the site permit for post-closure care of the site:

1)         Number of years of post-closure care required.

2)         Groundwater monitoring:

A)        Number of monitoring points;

B)        Parameters to be monitored;

C)        Frequency of sampling;

D)        Cost per parameter per sampling.

3)         Cover stabilization:

A)        Estimate of the area which is expected annually to require residual settlement or erosion control work;

B)        Annual cost of residual settlement and erosion control work;

C)        Annual cost of mowing.

e)         This Section does not grant authority to the Agency to require the operator to perform any of the indicated activities; however, if the site permit requires a closure activity, the operator must include the cost in the cost estimate.  Once the operator has completed an activity, the operator may file a permit application indicating that the activity has been completed, and zeroing that element of the cost estimate.
