§ 39-5-113.3. Oil and gas drilling rigs - apportionment of value.

(1) As soon after the assessment date as may be practicable, the assessor shall determine those oil or gas drilling rigs that were operating, stored, or maintained in the county during the preceding calendar year and shall mail or deliver two copies of a declaration to the place of business or drilling operation or to the residence of each person known or believed to own such rigs, or to the agent of such person. Such person or his agent shall list in such declaration all oil or gas drilling rigs owned by him, or in his possession, or under his control that were located in said county during the previous calendar year, attaching thereto the drilling logs of the respective rigs showing their various locations and corresponding dates. In addition, such person or his agent shall provide to the assessor of the first county in Colorado listed on each rig's log an inventory of that rig's equipment sufficient to determine a valuation for assessment. The original copy of the declaration shall be signed and returned to the assessor no later than the April 15 next following.

(2) The assessor, upon receiving such inventory and notification that his county was the first location of the rig in Colorado, shall determine its value and shall apportion such value between the counties in which the drilling rig was located during the preceding year and the districts thereof, in the proportion that the periods of time during which such equipment was located or maintained in such counties bear to the full calendar year. On or before June 15, the assessor shall furnish a copy of such valuation and apportionment to the owner of such equipment or to his agent and shall also transmit a copy thereof to the assessor of each county affected, together with a copy of the drilling log for that rig. For purposes of making such apportionment, the valuation of the oil or gas drilling rig made by the assessor of the first Colorado county on the log shall be used by all county assessors involved. In the subsequent counties, the assessor shall accept the returned declaration with the rig's name and location data as a proper filing.

(3) The values so apportioned shall be included in the affected counties' abstracts of assessment filed pursuant to section 39-5-123.

(4) This section shall apply to the apportionment of value of oil or gas drilling rigs and not the provisions of section 39-5-113.

(5) For purposes of this section "oil and gas drilling rigs" shall be defined by the property tax administrator pursuant to section 39-2-109 (1)(e), which definitions shall be uniform and consistent throughout the state.
