PERMANENT RULES
DEPARTMENT OF TRANSPORTATION
[Filed August 22, 2013, 10:53 a.m., effective September 22, 2013]
Effective Date of Rule: Thirty-one days after filing.
Purpose: The proposed change will authorize the department to issue permits and set limits for moving overweight divisible loads when a national emergency is declared by the president of the United States. The federal Moving Ahead for Progress in the 21st Century (MAP -21) provided the states the authority and criteria to establish a permitting process for allowing commercial vehicles to exceed the legal weight limits when transporting relief supplies to a declared emergency location.
Citation of Existing Rules Affected by this Order: Amending WAC 468-38-071.
Statutory Authority for Adoption: RCW 46.44.098 and 46.44.090.
Other Authority: Public Law 112-141, MAP 21, Section 1511.
Adopted under notice filed as WSR 13-13-056 on June 17, 2013.
Changes Other than Editing from Proposed to Adopted Version: The proposed rule as published in the Register, did not include the text in subsection (3)(H) [(4)(c)(iv)(H)] "except for activities that clear roadways, staging areas, or locations for temporary structures in specific areas in the disaster area."
Stakeholders agreed text should be added due to situations present in northeast coast states using emergency permitting following hurricane Sandy.

AMENDATORY SECTION (Amending WSR 11-17-130, filed 8/24/11, effective 9/24/11)
WAC 468-38-071 Maximums and other criteria for special permits—Divisible.
(1) Can a vehicle, or vehicle combination, acquire a permit to exceed the dimensions for legal vehicles in regular operation when moving items of a divisible nature? Yes. There are specific configurations that receive extra length, extra width, or extra height when carrying a divisible load.
(2) What configurations can be issued a permit, and how are they measured? The configurations and measurement criteria are:
(a) An overlength permit may be issued to a truck-tractor to pull a single trailer or semi-trailer, with a trailer length not to exceed fifty-six feet. The measurement for the single trailing unit will be from the front of the trailer (including draw bar when used), or load, to the rear of the trailer, or load, whichever provides the greater distance up to fifty-six feet. Rear overhang may not exceed fifteen feet.
(b) An overlength permit may be issued to a truck-tractor to pull a set of double trailers, composed of a semi-trailer and full trailer or second semi-trailer, with a combined trailer length not to exceed sixty-eight feet. The measurement for double trailers will be from the front of the first trailer, or load, to the end of the second trailer or load, whichever provides the greatest distance up to sixty-eight feet. Note: If the truck-tractor is carrying an allowable small freight compartment (dromedary box), the total combined length of the combination, combined trailer length notwithstanding, is limited to seventy-five feet.
(c) An overlength permit may be issued to a log truck pulling a pole-trailer, trailer combination, carrying two distinct and separate loads, as if it was a truck-tractor pulling a set of double trailers. Measurement for the log truck, pole-trailer, trailer combination will be from the front of the first bunk on the truck to the rear of the second trailer, or load, whichever provides the greatest distance up to sixty-eight feet.
(d) An overheight permit may be issued to a vehicle or vehicle combination, hauling empty apple bins, not to exceed fifteen feet high. Measurement is taken from a level roadbed. This permit may be used in conjunction with either of the overlength permits in (a) or (b) of this subsection. The permit may also provide an exemption from a front pilot/escort vehicle as required by WAC 468-38-100 (1)(h). The exemption does not limit the liability assumed by the permit applicant.
(e) An overheight permit may be issued to a vehicle or vehicle combination owned by a rancher and used to haul the rancher's own hay from the rancher's own fields to feed the rancher's own livestock, not to exceed fifteen feet high, measured from a level roadbed. This permit may be used in conjunction with either of the overlength permits in (a) or (b) of this subsection. The permit may also provide an exemption from a front pilot/escort vehicle as required by WAC 468-38-100 (1)(h). The exemption does not limit the liability assumed by the permit applicant.
(f) An overwidth permit, termed a tarping system permit, may be issued to a vehicle or vehicle combination for a divisible load when such vehicle is equipped with a tarping system as defined in WAC 468-38-073 (5)(n) and under the following conditions:
(i) The divisible load must be authorized by a tarping system permit in order to display the special conditions on the permit;
(ii) A tarping system permit is required for any divisible load exceeding one hundred and two inches (eight feet six inches) in width but not exceeding nine feet in width, all of which must be within the confines of the tarping system dimensions. For example, bulging of the tarping material, to accommodate the load, is not authorized;
(iii) A tarping system permit is authorized to be used in conjunction with either of the overlength permits authorized under (a) or (b) of this subsection; and
(iv) Vehicles operating with a tarping system permit are exempt from the requirements and restrictions listed in WAC 468-38-075(1).
(3) Are there any measurement exclusive devices related to these permits? Measurements should not include nonload-carrying devices designed for the safe and/or efficient operation of the vehicle, or vehicle combination components, for example: An external refrigeration unit, a resilient bumper, an aerodynamic shell, etc. Safety and efficiency appurtenances, such as, but not limited to, tarp rails and splash suppression devices, may not extend more than three inches beyond the width of a vehicle. The examples are not all inclusive.
(4) Are overweight permits available for divisible loads? Yes. There are specific criteria authorizing overweight permits to divisible loads.
(a) The secretary of transportation, or designee, may issue permits to department vehicles used for the emergent preservation of public safety and/or the infrastructure (i.e., snow removal, sanding highways during emergency winter conditions, emergent debris removal or retainment, etc.). The permits will also be valid for the vehicles in transit to or from the emergent worksite. The special permits may allow:
(i) Weight on axles in excess of what is allowed in RCW 46.44.041;
(ii) Movement during hours of the day, or days of the week, that may be restricted in WAC 468-38-175;
(iii) Exemption from the sign requirements of WAC 468-38-155(7) if weather conditions render such signs ineffectual; and
(iv) Movement at night, that may be restricted by WAC 468-38-175(3), by vehicles with lights that meet the standards for emergency maintenance vehicles established by the commission on equipment.
(b) Additional weight allowances are authorized through special permit for a segment of US-97 from the Canadian border to milepost 331.12 designated as a heavy haul industrial corridor. The permits will authorize vehicles to haul divisible loads weighing up to the Canadian inter-provincial weight limits and must comply with the following requirements:
(i) Vehicles applying for the Canadian weight special permit must be licensed to their maximum legal weight limit in Washington state.
(ii) Displaying the US-97 heavy haul industrial corridor permit does not waive registration fees, fuel taxes, operating authority requirements, future legislative or regulatory changes. Except as provided in the provisions for the heavy weight industrial corridor on US-97, all Washington state and federal laws must be complied with.
(iii) Routes of travel are strictly limited: Both directions of US-97 from the Canadian border at milepost 336.48 to milepost 331.12.
(iv) A Washington state axle spacing report is required for Canadian weight verification.
(v) The following descriptions indicate the maximum weight limits that will be permitted:
(A) Primary steering axle - 600 lbs. (272 kg) per inch (25.4 mm) of width of tire* with a maximum limit of 12,100 lbs.
(B) Other axles - 500 lbs. (227 kg) per inch of width of tire*.
(C) Single axles - 20,000 lbs. (9,100 kg) maximum.
(D) Tandem axles - 37,500 lbs. (17,000 kg) maximum.
*Width of tire is determined by tire side-wall nomenclature.
(E) Tridem axles.
