1. (a) Permit fee formulas.

   1. (1) The permit fee for a time permit is calculated by the following formula:

2. (b) Hubometer mileage.

   1. (1) A unit operated with a time permit must be equipped with a hubometer. The permittee must maintain the hubometer in good working condition.
   2. (2) Mileage for a time permit is determined by an amount estimated by the applicant for the first time permit, or from the unit's hubometer mileage reading from the previous time permit.
   3. (3) Actual mileage to be traveled is used to calculate the permit fee for a single-trip permit.

3. (c) Highway use factor.

   1. (1) The highway use factor for a time permit is 0.3.
   2. (2) The highway use factor for a single-trip permit is 0.6.

4. (d) Total rate per mile.

   1. (1) The total rate per mile is the combined mileage rates for width, height, and weight for the unit.
   2. (2) The mileage rate for width is $.06 per mile for each foot (or fraction thereof) above legal width.
   3. (3) The mileage rate for height is $.04 per mile for each foot (or fraction thereof) above legal height.
   4. (4) The mileage rate for a single axle or any axle within a group that exceeds 20,000 pounds, but is less than or equal to 25,000 pounds, is calculated by multiplying $.045 times the amount by which the axle or axle group weight exceeds the legal weight for the axle or axle group and dividing the resultant figure by 1,000 pounds.
   5. (5) The mileage rate for a single axle or any axle within a group that exceeds 25,000 pounds, but is less than or equal to 30,000 pounds, is calculated by multiplying $.055 times the amount by which the axle or axle group weight exceeds the legal weight for the axle or axle group and dividing the resultant figure by 1,000 pounds.

5. (e) Permit fees.

   1. (1) The minimum fee for a single-trip permit or time permit is either the calculated permit fee or $31, whichever is the greater amount.
   2. (2) The annual permit fee for an oil field rig-up truck is $52.
   3. (3) A unit that is overlength only must obtain a time permit with a fee of $31, and is not required to have a hubometer.
   4. (4) A unit that does not exceed legal size and weight limits and is licensed with a permit plate must purchase an annual permit with a permit fee of $52 per axle. The unit is not required to have a hubometer.
   5. (5) An applicant using a credit card to purchase a permit will pay a service charge of $1.00 in addition to the permit fee.
   6. (6) The permit fee for a trailer mounted unit is based on the overall width, overall height, and all axle weights, including the truck-tractor axles.

   7. (7) A unit with two or more axle groups that does not have a spacing of at least 12 feet between the closest axles of the opposing groups must have the permit fee calculated by the following method.

      1. (A) The axle group with the lowest weight will have the axle closest to the next axle group temporarily disregarded from its group in order to create a spacing of at least 12 feet between the two groups for fee calculation purposes.
      2. (B) An axle group will not have more than one axle disregarded.
      3. (C) The permit fee for the axle group with the temporarily disregarded axle must be based on the actual weight of the entire axle group minus the legal weight for the remaining axles of the group.

   8. (8) The CPO will calculate the renewed time permit fee in the following method.

      1. (A) An applicant requesting a permit for a unit that has traveled in excess of the mileage stated in the previous time permit must pay for the excess mileage traveled, in addition to the fee for the renewed time permit.
      2. (B) An applicant requesting a permit for a unit that has traveled less than the mileage stated on the previous time permit will receive a credit on the purchase price of the renewed time permit for that unit or another unit.
   9. (9) A refund is made to the applicant when the time permit process is stopped for all units listed in the applicant's account, provided the amount of the refund exceeds $31.

6. (f) Registration reduction.

   1. (1) A unit licensed for maximum legal weight will receive a reduction of 25% in the computation of the permit fee.
   2. (2) A unit licensed with a permit plate or a 72/144 hour temporary registration does not receive a registration reduction in the computation of the permit fee.
