Section NR 664.0144 - Cost estimate for long-term care

(1) The owner or operator of a disposal surface impoundment, disposal miscellaneous unit or landfill unit, or of a surface impoundment or waste pile required under ss. NR 664.0228 and 664.0258 to prepare a contingent closure and long-term care plan, shall have a detailed written estimate, in current dollars, of the annual cost of long-term care monitoring and maintenance of the facility according to the applicable long-term care rules in ss. NR 664.0117 to 664.0120, 664.0228, 664.0258, 664.0310 and 664.0603.

(2) During the active life of the facility, the owner or operator shall adjust the long-term care cost estimate for inflation within 60 days prior to the anniversary date of the establishment of the financial instrument or instruments used to comply with s. NR 664.0145. For owners or operators of disposal facilities using the net worth test, the long-term care cost estimate shall be updated for inflation as specified in s. 289.41(5) (d), Stats. The adjustment may be made by recalculating the long-term care cost estimate in current dollars or by using an inflation factor derived from the most recent implicit price deflator for gross domestic product published by the U.S. department of commerce in its Survey of Current Business as specified in pars. (a) and (b). The inflation factor is the result of dividing the latest published annual deflator by the deflator for the previous year.

(3) During the active life of the facility, the owner or operator shall revise the long-term care cost estimate within 30 days after the department has approved the request to modify the long-term care plan, if the change in the long-term care plan increases the cost of long-term care. The revised long-term care cost estimate shall be adjusted for inflation as specified in sub. (2).

(4) The owner or operator shall keep the following at the facility during the operating life of the facility: The latest long-term care cost estimate prepared in accordance with subs. (1) and (3) and, when this estimate has been adjusted in accordance with sub. (2), the latest adjusted long-term care cost estimate.
