Minnesota Administrative Rules

7045.0512 COST ESTIMATE FOR CORRECTIVE ACTION.

Subpart 1.

Cost estimate requirements.

The owner or operator shall have a written estimate, in current dollars, of the cost of performing corrective action in accordance with the requirements in part 7045.0484, subparts 2, item D; and 14. The corrective action cost estimate must equal the cost of implementing the corrective action plan when a concentration limit is first exceeded at the compliance point.

Subp. 2.

Yearly update of cost estimate.

The owner or operator shall adjust the corrective action cost estimate for inflation within 30 days after each anniversary of the date on which the first corrective action cost estimate was prepared. The adjustment must be made as specified in items A and B using an inflation factor derived from the annual Implicit Price Deflator for Gross National Product as found in the Survey of Current Business issued by the United States Department of Commerce. The inflation factor is the result of dividing the latest published annual deflator by the deflator for the previous year. Adjustments are made as follows:

A.

The first adjustment is made by multiplying the corrective action cost estimate by the inflation factor. The result is the adjusted corrective action cost estimate.

B.

Subsequent adjustments are made by multiplying the latest adjusted corrective action cost estimate by the latest inflation factor.

Subp. 3.

Cost estimate revisions.

The owner or operator shall revise the corrective action cost estimate whenever a change in the corrective action plan increases the cost of corrective action. The revised corrective action cost estimate must be adjusted for inflation as specified in subpart 2.

Subp. 4.

Record retention.

The owner or operator shall keep the following at the facility during the operating life and postclosure care period of the facility: the latest corrective action cost estimate prepared in accordance with subparts 1 and 3 and, when this estimate has been adjusted in accordance with subpart 2, the latest adjusted corrective action cost estimate.
