(1) Bids for new rigs will be solicited from manufacturers of oil drilling rigs to determine current replacement costs based on the depth rating listed below. For each depth rating listed below for oil drilling rigs, there will be two replacement cost categories. One category will represent current replacement cost of a mechanical rig and the second category will represent current replacement cost of an electric rig. Each rig as it is assessed will be placed in a value category based on its depth.

The depth capacity for drilling rigs will be based on the "Manufacturers Depth Rating." These replacement costs will then be depreciated to arrive at market value according to the schedule mentioned in (2) .

(2) The department shall prepare a ten-year trended depreciation schedule for oil drilling rigs. The trended depreciation schedule shall be derived from depreciation factors published by Marshall and Swift Publication Company. The "% good" for all drill rigs less than one year old shall be 100%. The trended depreciation schedule for tax year 2007 is listed below.

(3) In any year that the information required in (1) is not available for use by the department, oil drilling rigs shall be valued by using the previous year's schedule.

(4) This rule is effective for tax years beginning after December 31, 2006.
