Preamble Table of Contents Back to Top
The decision to consider the incorporation of these special permits into the HMR is based on special permits issued by PHMSA under 49 CFR part 107, subpart B (§§ 107.101 to 107.127) and the length of time these special permits have been in use with demonstrated records of safety. A special permit sets forth alternative requirements to the HMR by means that achieve a level of safety equal to or greater than that required by regulation and that are consistent with the public interest. Congress expressly authorized DOT to issue these variances in the Hazardous Materials Transportation Act of 1975.

Comments that addressed the recommendation of additional revisions to those proposed in the NPRM are beyond the scope of this rulemaking and, therefore, cannot be addressed for incorporation into the HMR in this final rule. Such revisions must first be presented in an NPRM to provide opportunity for comment from industry and the public. While we agree that certain beyond-the-scope issues merit PHMSA's consideration, we urge those commenters who submitted beyond-the-scope issues to request a change in the regulations by filing the recommendations as petitions for rulemakings in accordance with §§ 106.95 and 106.100.
Beyond-the-Scope comments to this rulemaking include the following:
The National Tank Truck Carriers (NTTC) had concerns about carrier-type status and limitations to non-agricultural operations, stating that all special permits should have these limitations removed. This rulemaking addresses incorporating special permits as currently written.
For SP 11209 and SP 13113, the American Trucking Association (ATA) contended that the special permits should not be limited to private motor carriers and agricultural operations, adding that PHMSA must provide evidence that for-hire carriers and non-agricultural activities are unsafe. As stated previously, this rulemaking addresses incorporating special permits as currently written. ATA is encouraged to further explain its arguments in favor of wider applicability of the provisions and submit a petition for rulemaking.
For SP 11209, the National Fire Protection Association (NFPA) questioned why the special permit requires that the cargo tanks be painted white, aluminum, or other light reflecting color, because it is not a requirement in NFPA 58 for propane storage tanks. This rulemaking addresses incorporating special permits as currently written.
For SP 11209, NTTC asked whether a carrier should follow the HMR requirements or the NFPA requirements in cases where the HMR adopts an NFPA requirement by citing it in the HMR regulatory text. NTTC states that in such cases, there are a number of places in NFPA pamphlets that conflict with requirements in the HMR. The commenter suggests that special permits should include a statement that cargo tanks must conform to a certain NFPA requirement unless that requirement conflicts with an HMR requirement. In its comment, NFPA provided the following example: “NFPA requires double bulkheads between compartments on cargo tanks hauling flammable liquids while Title 49 CFR does not.” While this may be an issue that requires further investigation, SP 11209 authorizes the transport of liquefied petroleum gases, not flammable liquids. We are unaware of conflicts between NFPA Pamphlet 58 and SP 11209 or any other incorporated by reference material, but we invite NTTC to identify any conflicts and present their issues in a petition for rulemaking. This rulemaking addresses incorporating special permits as currently written.
For SP 13113, the Agricultural Retailers Association (ARA) suggested that movements of liquid pesticide fumigants in MC 306, DOT 406, and DOT 57 containers should be authorized from distribution point to retail facility. The association stated that there is no safety difference between movements from distribution point to retail facility and movements from retail facility to farm. This rulemaking addresses incorporating special permits as currently written.
For SP 10950, the Far West Agribusiness Association, the Fertilizer Institute, and Dusty Farm Co-Op support the rulemaking, but recommend that we expand the current 50 air mile radius to a 100 air mile radius for consistency with the Federal Motor Carrier Safety Administration's (FMCSA) regulations. This rulemaking addresses incorporating special permits as currently written.
For SP 13554, Trinity Containers requested that, for nurse tanks, a percentage of the actual material thickness or five percent be used for the head and shell minimum thickness allowance. ARA stated that when SP 13554 was originally granted, the specifications of older nurse tanks were used to determine a minimum head and body thickness for a tank to pass the thickness test. The commenter stated that, currently, nurse tanks are built with a different diameter and grade of material, which allows the tanks to be built thinner than previously built, yet still conform to the ASME Code standards. The result is that many new nurse tanks do not meet the thickness thresholds in SP 13554 due to improved engineering. American Welding and Tank LLC stated that PHMSA should take into consideration the ASME Code thickness changes throughout the years applicable to one thickness for heads and one for shells. The commenter states that the head and shell minimum thickness allowance does not consider the tank diameter or the edition of the ASME Code in effect when the tanks were manufactured. American Welding requests that we incorporate an allowable reduction material thickness based on the actual thickness of the tank. This rulemaking addresses incorporating special permits as currently written.
Under its SP 13554 comments, ATA recommends that PHMSA incorporate standards that are available free of charge. No new standards were proposed to be incorporated into the HMR, nor adopted in this final rule. The free-of-charge comment is beyond the scope of this rulemaking.
Fisk Tank Carrier requested that we add the provisions of a seventh special permit, SP 14980, which authorizes the one-way transportation in commerce of liquefied petroleum gas (LPG) in certain non-DOT specification storage tanks by private carrier motor vehicle.
NFPA suggested that we incorporate by reference the 2011 edition of the NFPA 58 that was published in September of 2010. If not possible due to time constraints, they recommend that we adopt the 2008 edition.
NTTC objected to PHMSA incorporating by reference materials that are prepared by third party private entities when the material is not made publicly available to the regulated industry.
The Fertilizer Institute requested that we address a petition for rulemaking that they previously submitted and that requested PHMSA to require the testing of all nurse tanks regardless of illegible identification plates. The petition will be addressed in a separate future rulemaking.
III. Discussion of Amendments and Applicable Comments Back to Top
The six special permits addressed in this final rule that authorize cargo tank transportation operations not specifically permitted under the HMR were initially issued to members of industry associations or similar organizations. They have well-established safety records and therefore PHMSA has determined that they are excellent candidates for incorporation into the HMR. Incorporating these special permits into the HMR will eliminate the need for over 10,000 current grantees to reapply for the renewal of six special permits every four years and for PHMSA to process the renewal applications, thereby eliminating a significant paperwork burden both on industry and the government.
A discussion of incorporating the provisions of six special permits into the HMR and their applicable comments follows below. As discussed earlier in this preamble, most of the commenters are supportive of this rulemaking. Those comments that are within the scope of this rulemaking are discussed below.
The Fertilizer Institute pointed out that in the NPRM's preamble, we reversed the paragraph numbers in the preamble from the regulatory text for § 173.315(m)(2) and (m)(3). The NPRM's preamble error is noted. The regulatory text was correct in the proposed regulatory text, and the preamble discussion in this final rule reflects the correction of the printing error.
Lisa Anderson is opposed to incorporating some of the proposed special permits because she contends that they do not provide an equivalent level of safety as cargo tanks tested under the current requirements in Part 180 of the HMR. As discussed in the preambles of the NPRM and this final rule, we chose the six permits addressed in this rulemaking precisely because of their demonstrated safety records. Although the comment is duly noted, we do suggest that the commenter submit a petition for rulemaking.
SP 11209 authorizes the transportation of LPG in non-DOT specification cargo tank motor vehicles, commonly known as moveable fuel storage tenders, used exclusively for agricultural purposes. Moveable fuel storage tenders are used to supply LPG fuel to farmers for crop drying, crop irrigation, flame weeding, plant defoliation prior to harvest, and other agricultural operations.
This special permit has been in effect since 1994 and has been utilized by over 3,400 grantees. A review of the Hazardous Materials Incident Data library did not reveal any incidents related to this special permit over the past ten years. Each vehicle operated under this special permit conforms to the ASME Code in effect at the time of its manufacture. Provisions governing the design and use of these vehicles are included in NFPA 58, Liquefied Petroleum Gas Code.
Mr. James T. Osterhaus, NPGA, CHS Inc., and CHS Agri Service Center, submitted the following comments (see their full comments at http://www.regulations.gov). James Osterhaus took issue with the following sentence from the preamble text of the NPRM: “In addition, transportation of a moveable fuel storage tender to an LPG distribution facility for re-filling would be permitted only if it contains no more than five percent of its water capacity.” Mr. Osterhaus is correct that this sentence could be misleading because moveable fuel storage tenders are not permitted to be “refilled” at any location except the point of use. However, we believe that proposed § 173.5(d)(9), taken from the special permit, is clear: “Transportation of the movable fuel storage tender between its point of use and a liquefied petroleum gas distribution facility is authorized only if the cargo tank contains no more than five percent of its water capacity.” Mr. Osterhaus suggests that we add the following language for clarity, “A movable fuel storage tender may only be filled at the consumer's premises or point of use. Transportation of a moveable fuel storage tender containing more than five percent of its water capacity from a liquefied distribution facility to a consumer's premises or point of use is prohibited.” We agree that the first sentence of Mr. Osterhaus' suggestion would ensure clarity, and we have added it to § 173.5(d)(9). We believe the addition of the second sentence would be redundant.
The National Fire Protection Association (NFPA) recommends that we revise “NFPA Pamphlet 58” to read more correctly as “NFPA 58, Liquefied Petroleum Gas Code.” We agree and have made the correction each place it appears in this rulemaking (§§ 173.5 and 173.315 for SP 11209 and SP 13554, respectively). NFPA also recommends that we incorporate a more current edition of this Code into the HMR (see Beyond-the-Scope comments in Section II of this preamble).
Additionally, NFPA suggests that we revise the regulatory text for incorporating SP 11209 into § 173.5 by removing paragraphs (d)(1), (d)(2), (d)(3) and (d)(6) because the paragraphs duplicate the requirements in NFPA 58, Liquefied Petroleum Gas Code. We disagree with NFPA. We believe that deleting these paragraphs from the HMR is unnecessary and that the inclusion of the paragraphs provides a user-friendly aspect to this section. We are, therefore, leaving the paragraphs in place.
This final rule incorporates the terms of SP 11209 into the HMR as proposed in the NPRM with the exception of the addition of the following sentence to § 173.5(d)(9) for clarification: “A movable fuel storage tender may only be filled at the consumer's premises or point of use.” PHMSA is amending § 173.5 to authorize the transportation of LPG in moveable fuel storage tenders used exclusively for agricultural purposes and operated by a private motor carrier. (A “private motor carrier,” as defined in interpretation letters issued by PHMSA, is a carrier who transports the business's own products and does not provide such transportation service to other businesses). As proposed in the NPRM, a non-DOT specification cargo tank motor vehicle used as a moveable fuel storage tender must: (1) Have a minimum design pressure of 250 psig; (2) conform to the requirements of the ASME Code in effect at the time the cargo tank was manufactured and marked accordingly; (3) have a water capacity of 1,200 gallons or less; (4) conform to applicable requirements in NFPA 58, Liquefied Petroleum Gas Code; and (5) be mounted securely on a motor vehicle. In addition, the cargo tank must be filled as prescribed in § 173.315(b). When filled, transportation of a moveable fuel storage tender would be limited to movements over local roads between fields using the shortest practical distance. In addition, transportation of a moveable storage fuel tender to a moveable fuel storage tender facility would be permitted only if it contains no more than five percent of its water capacity.
SP 13113 authorizes the transportation of Division 6.1 liquid soil pesticide fumigants in MC 306 and DOT 406 cargo tank motor vehicles and DOT 57 portable tanks used exclusively for agricultural purposes. Liquid soil pesticide fumigants are used by farmers as an alternative to the agricultural use of methyl bromide to ensure the adequate protection of crops from pest infestation and to preserve agricultural productivity. Transportation of these materials is limited to private motor carriage and must be between a bulk loading facility and farms (including between farms) not exceeding 150 miles from one another.
This special permit has been in effect since 2002 and has been utilized by hundreds of grantees. A review of the Hazardous Materials Incident Data library did not reveal any incidents related to this special permit since the date of its issuance. Prior to 2002, when this material was classed as Dichloropropenes, 6.1, UN2047, PG III, it was routinely shipped, in accordance with § 173.242, in MC 306 and DOT 406 cargo tanks and DOT 57 portable tanks. The same tanks have been widely used to transport gasoline, a low flashpoint PG II liquid. The pressure relief systems and bottom discharge equipment on the cargo tanks offer equivalent safety in terms of containment and operation of pressure relief systems. Also, stainless steel DOT 57 portable tanks provide comparable containment to metal, rigid plastic, and composite Intermediate Bulk Containers (IBCs), which are authorized for transport of Division 6.1 liquid soil pesticide fumigants under § 173.202.
PHMSA is incorporating the terms of SP 13113 into the HMR by amending § 173.5. MC 306 and DOT 406 cargo tank motor vehicles used for the transportation of these fumigants must: (1) meet qualification and maintenance requirements (including periodic testing and inspection) in accordance with Subpart E of Part 180; and (2) conform to the pressure relief system requirements specified in § 173.243(b)(1). In addition, MC 306 cargo tank motor vehicles must be equipped with stop-valves capable of being remotely closed by manual and mechanical means; and DOT 406 cargo tanks must conform to the bottom outlet requirements specified in § 173.243(b)(2). DOT 57 portable tanks used to transport Division 6.1 liquid soil pesticide fumigants must be constructed of stainless steel.
SP 12284 authorizes the transportation in commerce of certain hazardous materials used for roadway striping in non-DOT specification cargo tanks. These non-DOT specification cargo tanks are used for the low hazard job of applying roadway striping to paved roads throughout the United States.
This special permit has been in effect since 1999 and has been utilized by over 100 grantees. A review of the Hazardous Materials Incident Data library did not reveal any incidents related to this special permit since the date of its issuance. Based on this safety record, PHMSA is incorporating the provisions of SP 12284 into the HMR by adding a new paragraph (c) to § 173.5a to authorize the transportation of certain hazardous materials used for roadway striping in non-DOT specification cargo tanks provided the conditions specified in the new paragraph are met. The new paragraph (c) specifies conditions that include packaging specifications, inspection and testing requirements, requirements for maintaining records, and operational controls. Consistent with the special permit, paragraph (c) includes certain/special marking requirements that are in addition to the applicable marking and placarding requirements in subparts D and F. The section title heading is also revised to reflect the addition of non-DOT specification cargo tanks used for roadway striping into this section. Finally, § 173.242(b) is revised to include the authorization to use non-DOT specification cargo tanks used for roadway striping.
SP 13341 authorizes the transportation by private motor carrier of LPG in consumer storage containers in quantities greater than five percent of the container's water capacity. The storage containers designated in the special permit are designed for permanent installation on consumer premises. The special permit authorizes one-way transportation only, from the consumer location to the container owner's nearest LPG plant.
This special permit has been in effect since 2004 and has been utilized by several thousand grantees. A review of the Hazardous Materials Incident Data library did not reveal any incidents related to this special permit since the date of its issuance. Prior to 1998, consumer storage containers filled with LPG to greater than five percent water capacity were routinely transported without any known incidents. The prohibition of transporting containers filled to more than five percent water capacity resulted from concern of the potential for confusion between ASME and DOT tanks, as ASME tanks are not designed to be lifted by the lugs with product inside. This final rule requires lifting with slings, not by the lugs. Also, transporting a tank with some product is sometimes preferable from a safety standpoint than removing LPG from a tank at a residence. NPGA, CHS Inc., and CHS Agri Service Center offered additional safety and efficiency information concerning this special permit in their comments (see their comments at http://www.regulations.gov).
PHMSA is incorporating the terms of SP 13341 into the HMR by revising § 173.315(j) to authorize the transportation of LPG in consumer storage containers in quantities greater than five percent of the container's water capacity. The storage container must have a water capacity not exceeding 500 gallons and be ASME “U” stamped to indicate that it was designed and constructed in accordance with ASME Code requirements. In addition, the container must be inspected for leaks, corroded or abraded areas, dents, weld distortions, or any other conditions that could make the container unsafe for transportation. PHMSA is also requiring that: (1) Only one storage container be transported at one time on a motor vehicle; (2) the storage container be lifted by slings, not by lifting lugs; and (3) the storage container be loaded and secured on the motor vehicle so that the container is well-secured against movement and completely within the envelope of the vehicle. Finally, transportation is limited to one-way movement from the consumer's premises to the container owner's nearest facility.
Nurse tanks mounted on field trucks. SP 10950 authorizes the use of a nurse tank securely mounted on a field truck. Field trucks are specifically designed and equipped to improve safety and efficiency by being more maneuverable and more stable than a farm wagon when moving over hilly terrain. A definition for field trucks is specified in § 173.315 as new paragraph (m)(3)(iv). These trucks are operated in remote rural areas in eastern Washington, Oregon, and northern Idaho within a short distance of the fertilizer distribution point. The special permit has been in effect since 1993 and has been utilized by over one hundred grantees. A review of the Hazardous Materials Incident Data library did not reveal any incidents related to this special permit since the date of its issuance. Tanks operated under this special permit are subject to the periodic testing requirements under Subpart E of Part 180.
For SP 10950 provisions, ATA also requested that we incorporate an exception from the security plan requirements “similar to the exemption afforded to users of anhydrous ammonia nurse tanks.” If ATA is referring to SP 13554, Item 11, second bullet, that provision specifically requires conformance to the security plan requirements. Users of SP 13554 were not excepted from security requirements, and as stated earlier in this preamble, we are not deviating from the current special permit provisions in this rulemaking. Therefore, the security plan requirements in Subpart I of Part 172 will remain applicable to nurse tanks mounted on field trucks. PHMSA is incorporating the provisions of SP 10950 into the HMR by adding a new paragraph (m)(3) to § 173.315.
Nurse tanks with missing or illegible ASME plates. As indicated above, nurse tanks must be manufactured in accordance with the applicable ASME Code requirements in effect at the time of manufacture. The ASME Code requires tanks built to its specifications to have an attached plate that lists the manufacturer, maximum allowable working pressure, minimum design metal temperature, and the year of manufacture. A number of nurse tanks are missing the required ASME plates or have illegible ASME plates. SP 13554 permits the continued use in anhydrous ammonia service of nurse tanks with missing or illegible ASME plates provided the tanks are inspected and tested. Specifically, the tanks must undergo an external visual inspection and testing using the procedures specified in § 180.407(d), a thickness test using the procedures specified in § 180.407(i), and a pressure test using the procedures specified in § 180.407(g). The special permit also establishes minimum head and shell thickness, and nurse tanks not meeting those levels must be removed from service. Nurse tanks that pass the above-described tests must be marked with a unique owner's identification number and must pass the same tests at least every five years to remain in service.
In this final rule, PHMSA is incorporating the terms of SP 13554 into the HMR by adding a new paragraph (m)(2) in § 173.315. Existing nurse tanks with missing or illegible ASME plates that successfully pass the required inspections and tests and are marked with a unique identifier are authorized to remain in service.
Additionally, in § 171.7, we are revising the entry, American Society of Mechanical Engineers (ASME) and the National Fire Protection Association (NFPA) to reflect the addition of the incorporated by reference materials to the applicable adopted regulatory text.
In § 173.23, we are redesignating current paragraph (h) as new paragraph (i) and adding a provision to new paragraph (h) that authorizes packagings permanently marked with a special permit number for which the provisions of the special permit were incorporated into the HMR to continue to be used for the life of the packagings without removing or obliterating the special permit markings. This provision will serve to avoid imposing the burden of requiring the removal from service of such packagings while the markings are removed or obliterated.
Finally, in § 173.242, we are revising paragraph (b) to reflect the authorization of non-DOT specification cargo tanks used for roadway striping. IV. Rulemaking Analyses and Notices Back to Top
This final rule addresses covered subject items (2), (3), and (5) and would preempt any State, local, or Indian tribe requirements not meeting the “substantively the same” standard. Federal hazardous materials transportation law provides at 49 U.S.C. § 5125(b)(2) that, if PHMSA issues a regulation concerning any of the covered subjects, PHMSA must determine and publish in the Federal Register the effective date of Federal preemption. The effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. The effective date of Federal preemption is 90 days after the publication of this final rule in the Federal Register.
Decrease in Annual Burden Costs:$7,400.
In an aquatic or wetland environment, ammonium hydroxide would cause fish, planktonic, and benthic organism mortality in the vicinity of the release, the amount depending on the volume of anhydrous ammonia released. The chemical would also strip protective oils from the feathers of shore birds, causing drowning or infection. Such die-offs could spur high nutrient levels that could stimulate noxious blooms of algae. Terrestrial vegetation would also be either damaged or killed, depending on atmospheric concentrations.
2.In § 171.7, in the paragraph (a)(3) table, in the second column, “49 CFR reference,” under the entry, National Fire Protection Association, the entry “NFPA 58—Liquefied Petroleum Gas Code, 2001 Edition” is amended by adding the section “173.5” in appropriate numerical order.
