Cost Estimate for Post-closure Care

Section 807 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.
