(a) General. The information in this section applies to single-trip permits issued under Transportation Code, Chapter 623, Subchapter D. The department will issue permits under this section in accordance with the requirements of §219.11 of this title (relating to General Oversize/Overweight Permit Requirements and Procedures).     
      (b) Overweight loads.      
        (1) The maximum weight limits for an overweight permit are specified in §219.11(d).       
        (2) The applicant shall pay, in addition to the single-trip permit fee of $60, the applicable highway maintenance fee.       
        (3) The applicant must also pay the vehicle supervision fee (VSF) for a permit issued for an overweight vehicle and load exceeding 200,000 pounds gross weight.                  (A) The VSF is $35 if:                      (i) the vehicle and load do not exceed 254,300 pounds gross weight;                       (ii) there is at least 95 feet of overall axle spacing; and                       (iii) the vehicle and load do not exceed maximum permit weight on any axle or axle group, as described in §219.11(d).                     (B) The VSF is $500 if:                      (i) there is less than 95 feet of overall axle spacing;                       (ii) the vehicle and load exceed maximum permit weight on any axle or axle group, as described in §219.11(d); or                       (iii) the vehicle and load exceed 254,300 pounds gross weight. However, for a vehicle and load described in this subparagraph, the VSF is reduced from $500 to $100 if no bridges are crossed, and the VSF is reduced from $500 to $35 for an additional identical load that is to be moved over the same route within 30 days of the movement date of the original permit.                     (C) An applicant must pay the VSF at the time of permit application in order to offset department costs for analyses performed in advance of issuing the permit. A request for cancellation must be in writing and received by the department prior to collection of the structural information associated with the permit application. If the application is canceled, the department will return the vehicle supervision fee.         
        (4) An applicant applying for a permit to move a load that is required for the fulfillment of a fixed price public works contract that was entered into prior to the effective date of this section, and administered by federal, state, or local governmental entities, will not be required to pay the vehicle supervision fee, provided the applicant presents proof of the contract to the department prior to permit issuance.       
        (5) When the department has determined that a permit can be issued for an overdimension load exceeding 200,000 pounds gross weight, all remaining fees are due at the time the permit is issued.       
        (6) Unless the permit is issued for a load under subsection (c) of this section, this permit may not be used for a container, including a trailer or an intermodal container, loaded with divisible cargo.       
        (7) An applicant requesting a permit to move an overdimension load that is between 200,001 and 254,300 pounds total with less than 95 feet overall axle spacing, or is over the maximum permitted weight on any axle or axle group, or is over 254,300 pounds gross weight, or the weight limits described in §219.11(d), must submit the following items to the department to determine if the permit can be issued:                  (A) a detailed loading diagram which indicates the number of axles, the number of tires on each axle, the tire size on each axle, the distance between each axle, the tare and gross weight on each axle, the transverse spacing of each set of dual wheels, the distance between each set of dual wheels, the load's center of gravity, the distance from the center of gravity to the center of the front bolster, the distance from the center of gravity to the center of the rear bolster, the distance from the center of the front bolster to the center of the fifth wheel of the truck, the distance from the center of the rear bolster to the center of the closest axle, and any other measurements as may be needed to verify that the weight of the overdimension load is adequately distributed among the various axle groups in the amounts indicated by the loading diagram;                   (B) a map indicating the exact beginning and ending points relative to a state highway;                   (C) a completed form prescribed by the department, attesting to the facts regarding the applicant's agreement to transport the shipment;                   (D) the vehicle supervision fee as specified in paragraph (3) of this subsection; and                   (E) the name, phone number, and fax number of the applicant's licensed professional engineer who has been approved by the department.         
        (8) The department will select a tentative route based on the physical size of the overdimension load excluding the weight. The tentative route must be investigated by the applicant, and the department must be advised, in writing, that the route is capable of accommodating the overdimension load.       
        (9) Before the permit is issued, the applicant's TxDOT approved licensed professional engineer shall submit to the department and TxDOT a written certification that includes a detailed structural analysis of the bridges on the proposed route demonstrating that the bridges and culverts on the travel route are capable of sustaining the load. The certification must be approved by TxDOT and submitted to the department before the permit will be issued.       
      (c) Drill pipe and drill collars hauled in a pipe box.      
        (1) A vehicle or combination of vehicles may be issued a permit under Transportation Code, §623.071, to haul drill pipe and drill collars in a pipe box.       
        (2) The maximum width must not exceed 10 feet.       
        (3) The axle weight limits must not exceed the maximum weight limits as specified in §219.11(d)(3).       
        (4) The height and length must not exceed the legal limits specified in Transportation Code, Chapter 621, Subchapter C.       
        (5) The permit will be issued for a single-trip only. For loads over 80,000 pounds, the applicant must pay the single-trip permit fee, in addition to the highway maintenance fee specified in Transportation Code, §623.077.       
        (6) The permit is valid only for travel on any farm-to-market and ranch-to-market road, and such road will be specified on the permit; however, the permitted vehicle will not be allowed to cross any load restricted bridge when exceeding the posted capacity of the bridge.       
        (7) Movement will be restricted to daylight hours only.       
      (d) Houses and storage tanks.      
        (1) Unless an exception is granted by TxDOT, the department will not issue a permit for a house or storage tank exceeding 20 feet in width.       
        (2) The issuance of a permit for a house or storage tank exceeding 20 feet in width will be based on:                  (A) the amount of inconvenience and hazard to the traveling public, based on traffic volume;                   (B) highway geometrics and time of movement; and                   (C) the overall width, measured to the nearest inch, of the house, including the eaves or porches.         
        (3) A storage tank must be empty.       
        (4) The proposed route must include the beginning and ending points on a state highway.       
        (5) A permit may be issued for the movement of an overweight house provided:                  (A) the applicant completes and submits to the department a copy of a diagram for moving overweight houses, as shown in Figure: 43 TAC §219.12(e) of this section;                   (B) each support beam, parallel to the centerline of the highway, is equipped with an identical number of two axle groups which may be placed directly in line and across from the other corresponding two axle group or may be placed in a staggered offset arrangement to provide for proper weight distribution;                   (C) that, when a support beam is equipped with two or more two axle groups, each two axle group is connected to a common mechanical or hydraulic system to ensure that each two axle group shares equally in the weight distribution at all times during the movement; and when the spacing between the two axle groups, measured from the center of the last axle of the front group to the center of the first axle of the following group, is eight feet or more, the front two axle group is equipped for self-steering in a manner that will guide or direct the axle group in turning movements without tire scrubbing or pavement scuffing; and                   (D) the department conducts a detailed analysis of each structure on the proposed route and determines the load can be moved without damaging the roads and bridges.         
        (6) The department may waive the requirement that a loading diagram be submitted for the movement of an overweight house if the total weight of all axle groups located in the same transverse plane across the house does not exceed the maximum weight limits specified in §219.11(d)(2).       
      (e) Diagram for moving overweight houses. The following Figure: 43 TAC §219.12(e) indicates the type of diagram that is to be completed by the permit applicant for moving an overweight house. All measurements must be stated to the nearest inch.
