    SUMMARY: On August 18, 1997, RSPA published a final rule adopting 
    certain safety standards applicable to cargo tank motor vehicles in 
    liquefied compressed gas service. In response to petitions for 
    reconsideration filed by Farmland Industries, Inc. (Farmland), The 
    Fertilizer Institute (TFI), and AmeriGas Propane, L.P. (AmeriGas), RSPA 
    is revising a requirement concerning the daily pressure testing of 
    transfer hoses on these cargo tank motor vehicles, and the agency is 
    revising Sec. 171.5(a) for consistency with Sec. 178.337-11(a)(1)(i) by 
    removing a hose rupture (i.e., incomplete separation) as a condition 
    that causes the internal self-closing stop valve to function. This 
    action grants certain petitions for reconsideration of the final rule 
    pertaining to effective and practical standards to assure the integrity 
    of transfer hoses used in unloading operations. Also, in this final 
    rule, RSPA is granting the request by Farmland and TFI to extend the 
    expiration of the final rule requirements for four months, to July 1, 
    1999. RSPA is denying the request by AmeriGas for an immediate stay of 
    the provisions of Sec. 171.5(a)(1)(iii) and the AmeriGas request for 
    reconsideration of: The provision in Sec. 171.5(c) setting forth an 
    expiration date for the final rule requirements; and RSPA's 
    interpretation of the attendance requirements in Sec. 177.834(i) that a 
    qualified person must always maintain an unobstructed view of the cargo 
    tank. Additionally, this action makes editorial revisions and clarifies 
    certain provisions adopted in the final rule.
    
    DATES: This final rule is effective December 10, 1997.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        On August 18, 1997, RSPA published a final rule under Docket No. 
    RSPA-97-2133 (HM-225) [62 FR 44038]. The final rule revised and 
    extended requirements published in an interim final rule (IFR) on 
    February 19, 1997, concerning the operation of cargo tank motor 
    vehicles (CTMVs) in certain liquefied compressed gas service. The final 
    rule requires a specific marking on affected CTMVs and requires motor 
    carriers to comply with additional operational controls intended to 
    compensate for the failure of passive emergency discharge control 
    systems to function as required by the Hazardous Materials Regulations 
    (HMR; 49 CFR Parts 171-180). The operational controls specified in the 
    final rule provide an alternative to compliance with Sec. 178.337-
    11(a)(1)(i) and are intended to ensure an acceptable level of safety 
    while the industry and government continue to work to develop an 
    emergency discharge control system that effectively stops the discharge 
    of hazardous materials from a cargo tank if any attached hose or piping 
    is separated.
        Petitions for reconsideration of the August 18, 1997 final rule 
    were filed by The National Propane Gas Association (NPGA), Farmland 
    Industries, Inc. (Farmland), The Fertilizer Institute (TFI) and jointly 
    by Ferrellgas, L.P., Suburban Propane, L.P., AmeriGas Propane, L.P. 
    (AmeriGas), Agway Petroleum Corporation, Cornerstone Propane Partners, 
    L.P., and National Propane, L.P. On September 26, 1997, Ferrellgas, 
    L.P., Suburban Propane, L.P., Agway Petroleum Corporation, Cornerstone 
    Propane Partners, L.P., and National Propane, L.P. withdrew their names 
    from the jointly-filed petition for reconsideration. Petitioner 
    AmeriGas, however, continues to seek relief through the September 17, 
    1997 petition for reconsideration. On October 2, 1997, NPGA withdrew 
    its petition for reconsideration. On November 5, 1997, National Private 
    Truck Council (NPTC) filed a petition for reconsideration. Although the 
    petition was filed by NPTC after the close of the petition period, and 
    RSPA has not accepted the petition, all NPTC's issues have been 
    considered since NPTC raised issues identical to those raised by other 
    petitioners.
        Petitioners Farmland and TFI seek reconsideration of two provisions 
    of the August 18, 1997 final rule. Specifically, they request 
    reconsideration of the requirement in Sec. 171.5(a)(1)(i) that a 
    transfer hose be subjected to full transfer pressure before commencing 
    the first transfer each day. They also ask RSPA to reconsider the 
    expiration date of the August 18, 1997 final rule requirements; they 
    request a four-month extension of the expiration date to July 1, 1999.
        AmeriGas seeks: (1) Reconsideration and an immediate stay of the 
    requirement in Sec. 171.5(a)(1)(iii) that the qualified person 
    unloading a CTMV promptly activate the internal self-closing stop valve 
    and promptly shut down all motive and auxiliary power in the event of 
    an unintentional release of lading to the environment during transfer; 
    (2) immediate withdrawal of RSPA's interpretation of its long-standing 
    attendance requirements in Sec. 177.834(i) pending further rulemaking 
    after notice and comment; (3) withdrawal of the expiration date in 
    Sec. 171.5(c); (4) deletion of the word ``rupture'' as it appears in 
    Sec. 171.5(a); and (5) withdrawal of the requirement in 
    Sec. 171.5(a)(1)(i) that the transfer hose be subjected to full 
    transfer pressure before commencing the first transfer each day.
    
    II. Petitions Granted
    
    A. Daily Pressure Testing of Transfer Hoses
    
        In Sec. 171.5(a)(1)(i), RSPA required that a transfer hose be 
    subject to full transfer pressure before the first unloading of product 
    each day. This provision applied to all CTMVs operating under the terms 
    of the temporary regulation specified in Sec. 171.5.
        Petitioners assert that, because most large CTMVs (``transports,'' 
    typically used for bulk plant deliveries) do not have a separate back-
    to-tank product bypass line, energizing the pump when the receiving 
    tank's liquid shutoff valve is closed may damage the pump vanes, result 
    in failure of the shaft seals and other components, and place high 
    torsional loads on the power take-off (PTO) drive shaft.
        In addition, petitioners state that no additional safety measures 
    are needed for small CTMVs (``bobtails,'' typically used for local 
    deliveries) because they are generally equipped with a separate back-
    to-tank product bypass valve. Petitioners state that, in the process of 
    preparing lines for product transfer from a small CTMV, the full length 
    of transfer hose is charged to pump discharge
    
    [[Page 65189]]
    
    pressure, thereby providing an opportunity to prove the integrity of 
    the transfer system prior to each delivery.
        Recognizing the merit of the petitioners' comments regarding the 
    transfer hose pressure standard adopted in the final rule, RSPA 
    published an advisory guidance that communicated the agency's agreement 
    with the petitioners' claim that some cargo tank pumping systems are 
    not capable of safely pumping against a closed product valve without 
    being damaged (62 FR 49171; September 19, 1997) . Therefore, 
    Sec. 171.5(a)(1)(i) is revised to allow an operator to determine the 
    leakproofness of a discharge system (including hose) by requiring that 
    the pressure in the discharge system reach at least equilibrium with 
    the pressure inside the cargo tank prior to transfer. After the 
    operator verifies leakproofness of the discharge system, delivery may 
    commence.
        RSPA is also amending Sec. 171.5(a)(1)(i) by removing the wording 
    ``and equipment'' from the third sentence to clarify that only the 
    piping, hose and hose fittings must be tested daily. There is no 
    requirement to test the entire cargo tank on a daily basis.
    
    B. Hose Separation Versus Hose Rupture
    
        Petitioner AmeriGas notes RSPA's use of the word ``rupture[d]'' in 
    Sec. 171.5(a) with respect to comparable requirements in Sec. 178.337-
    11(a)(1)(i) concerning operation of the internal self-closing stop 
    valve. The petitioner states that the word ``rupture[d]'' is more 
    commonly used to denote a ``leak or partial failure'' rather than an 
    actual separation, thus creating an undesirable potential for 
    confusion. Therefore, AmeriGas requests that the word ``rupture[d]'' be 
    stricken from the regulatory language.
        RSPA agrees that the word ``ruptured'' could be construed as adding 
    new meaning to requirements pertaining to the emergency operation of 
    the internal self-closing stop valve that was not intended in the 
    development of the final rule. Therefore, Sec. 171.5(a) is amended by 
    removing the wording ``ruptured or'' to make this provision consistent 
    with requirements in Sec. 178.337-11(a)(1)(i).
    
    C. March 1, 1999 Expiration Date of the Temporary Final Rule
    
        Petitioners TFI and Farmland request that RSPA reconsider the March 
    1, 1999 expiration date of the requirements in Sec. 171.5. The 
    petitioners request a four-month extension of the alternative 
    requirements in Sec. 171.5--until July 1, 1999--to avoid expiration of 
    the requirements at the beginning of the fertilizer industry's peak 
    delivery season.
        RSPA is granting a request by TFI and Farmland to extend the 
    expiration date until July 1, 1999. This decision is based on RSPA's 
    understanding that industry will continue to make good faith efforts in 
    developing an emergency discharge control system that offers an equal 
    or higher level of safety as that in longstanding provisions in 
    Sec. 178.337-11(a)(1)(i).
    
    III. Petitions Denied
    
    A. Prompt Activation of the Internal Self-Closing Stop Valve
    
        In its petition, AmeriGas contends that it is impossible to achieve 
    immediate full compliance with the requirement in Sec. 171.5(a)(1)(iii) 
    that a qualified person unloading a small CTMV promptly activate the 
    internal self-closing stop valve and promptly shut down all motive and 
    auxiliary power equipment if there is an unintentional release of 
    lading to the environment during transfer. AmeriGas claims this rule 
    constitutes a new operator attendance requirement that can only be 
    satisfied by using remote-controlled equipment that is not currently in 
    service on more than an experimental basis and that such equipment 
    cannot be put into service in less than a matter of months.
        In the February 1997 emergency interim final rule (IFR), RSPA first 
    adopted additional requirements for the person who attends the 
    unloading of a CTMV to be within arm's reach of a means for closure 
    (emergency shut-down device) of the internal self-closing stop valve or 
    other device that will immediately stop the discharge of product from 
    the cargo tank [62 FR 7643, February 19, 1997]. Use of an ``electro-
    mechanical'' device as a means of closure was discussed in that rule. 
    Based on comments to the IFR, RSPA revised Sec. 171.5(a)(1)(iii)(C), in 
    the August final rule, to set forth three ways to achieve prompt 
    stoppage of lading discharge from the cargo tank by: (1) complying with 
    the requirements in Sec. 178.337-11(a)(1)(i); (2) using a qualified 
    person positioned within arm's reach of the mechanical means of closure 
    of the internal self-closing stop valve throughout the unloading 
    operation, except during the short period necessary to engage or 
    disengage the motor vehicle PTO or other mechanical, electrical, or 
    hydraulic means used to energize the pump and other components of a 
    cargo tank's discharge system; or (3) using a remote-controlled system 
    that is capable of stopping the transfer of lading by use of a 
    transmitter carried by a qualified person unloading the cargo tank.
        RSPA notes that the NPGA special task force, organized in part to 
    develop plans to provide for continued safe operation of existing 
    propane cargo tanks, concentrated much of its efforts on development of 
    remote-controlled devices that may be activated by the person attending 
    an unloading operation [comments of Mr. McHenry, NPGA, June 23, 1997 
    public meeting]. A representative of the NPGA special task force 
    reported progress on the development of remote-controlled devices at a 
    June 23, 1997 public meeting [comments of Mr. McHenry, NPGA]. 
    Petitioner AmeriGas also provided a report on its progress in 
    developing an effective, low-cost remote-controlled system using radio 
    frequency technology [comments of Mr. McEnroe, AmeriGas, June 23, 1997 
    public meeting transcript, pages 5, 45, 56, and 57]. AmeriGas provided 
    RSPA with an update on its progress in a November 13, 1997 meeting. The 
    NPGA's July 24, 1997 petition for rulemaking (P-1346) calls for RSPA to 
    adopt a new provision in Sec. 178.337-11(a)(1)(iii) for a variety of 
    systems that are capable of closing the internal liquid discharge valve 
    by remote means.
        The public record contains favorable accounts by several propane 
    dealers who have installed remote-controlled systems on their fleets of 
    CTMVs [comments of Mr. Schuler, REMTRON, June 23, 1997 public meeting 
    transcript, pages 59 and 60; comments of Mr. Stillwaggon, H.R. Weaver 
    Co.; and comments of Mr. McEnroe, AmeriGas, September 30, 1997 public 
    meeting transcript, pages 42 and 61, respectively].
        Industry representatives have stated that they have had good 
    results with using radio-frequency, remote-controlled systems [comments 
    of Mr. McEnroe, AmeriGas, public meeting transcript, June 23, 1997, 
    page 46; Dr. Coady, Hick's Gas, June 23, 1997 public meeting 
    transcript, pages 92 and 102]. A representative of Hicks Gas, one of 
    the larger independent marketers of propane, stated that his company 
    has been developing and refining remote-control shutdown systems on 
    some of its trucks for the past three years [comments of Dr. Coady, 
    Hick's Gas, June 23, 1997 public meeting transcript, page 92].
        During two public meetings (June 23, 1997 and September 30, 1997) 
    industry representatives presented information on radio frequency, 
    remote-controlled systems, some with basic features and others with 
    more sophisticated applications, that can be used on most
    
    [[Page 65190]]
    
    CTMVs. Additionally, they represented that the installation 
    instructions for these systems are simple enough that a fleet mechanic 
    who has a working knowledge of a vehicle's air and electrical systems 
    generally has the experience and tools necessary to install and proof-
    test a system within a period of two or three hours.
        The advantage of a remote-controlled device has been demonstrated 
    during an incident involving a propane release on November 3, 1997 near 
    Udina, Illinois. The driver, using a remote-controlled device, promptly 
    activated closure of the internal self-closing stop valve without 
    ignition of the propane.
        RSPA does not agree that operators of CTMVs have no practical means 
    of compliance. The public record contains information that some 
    operators began installing remote-controlled systems shortly after 
    issuance of the February 19, 1997 interim final rule. In addition, the 
    Federal Highway Administration's (FHWA) compliance policy emphasizes 
    increased awareness about the rule and its safety benefits, as opposed 
    to immediate enforcement. If a company shows good faith efforts to 
    comply with the provisions of Sec. 171.5, FHWA's policy is to not 
    pursue civil penalty enforcement actions.
        Therefore, based on the above information, this part of the 
    AmeriGas petition for reconsideration of the final rule is denied.
        RSPA believes there is a need to clarify that while the first 
    sentence of Sec. 171.5(a)(1)(iii)(C) allows use of a remote-controlled 
    system to promptly activate the internal self-closing stop valve in the 
    event of an unintentional discharge, the second sentence provides 
    limited relief from the attendance requirements in Sec. 177.834(i)(3). 
    Specifically, Sec. 177.834(i)(3) requires a qualified person who is 
    attending the unloading of a cargo tank to be awake, have an 
    unobstructed view of the cargo tank, and be within 25 feet of the cargo 
    tank at all times during unloading. Therefore, the second sentence in 
    Sec. 171.5(a)(1)(iii)(C) is revised to clarify that where a remote-
    controlled system is used, the attendance requirements in 
    Sec. 177.834(i)(3) are satisfied when the qualified person attending is 
    awake, is carrying a transmitter that can activate the closure of the 
    internal self-closing stop valve, remains within the operating range of 
    the transmitter, and maintains an unobstructed view of the cargo tank 
    when the internal self-closing stop valve is open.
        Also, Sec. 171.5(a)(1)(iii)(B) is revised to clarify that a 
    qualified person must be positioned within arm's reach of a mechanical 
    means of closure for the internal self-closing stop valve only when 
    this valve is open, except for the short duration necessary to engage 
    or disengage the motor vehicle PTO or other mechanical, electrical or 
    hydraulic means used to energize the pump and other components of a 
    cargo tank motor vehicle's discharge system. All of these functions 
    occur at or immediately adjacent to the cargo tank in proximity to a 
    means for closure of the internal self-closing stop valve.
    
    B. RSPA Has Not Developed a ``New Interpretation'' of Its Long-Standing 
    Attendance Requirement in Sec. 177.834(i)
    
        In its petition, AmeriGas states that, in the August 18, 1997 final 
    rule, RSPA announced a new interpretation of the long-standing 
    attendance requirements set forth at Sec. 177.834(i). AmeriGas contends 
    that this interpretation should be withdrawn because it: (1) is 
    inconsistent with the regulatory language; (2) was announced without 
    notice or opportunity to comment, in violation of the Administrative 
    Procedure Act (APA) (see 5 U.S.C. 553); and (3) is inconsistent with 
    normal industry practice that has been ``accepted for decades without 
    question.''
        AmeriGas's arguments are invalid because RSPA's position with 
    regard to the meaning of Sec. 177.834(i) is consistent with the 
    regulatory history and plain language of that requirement. Furthermore, 
    the public was given notice of the rulemaking that gave rise to the 
    attendance requirements and an opportunity to comment. Indeed, comments 
    to that rulemaking reflect that industry understood that restrictions 
    on the person attending the unloading of hazardous materials from 
    CTMV's were being proposed. Additional notice and an opportunity to 
    comment are, therefore, not required under the APA. Finally, there is 
    no validity to the assertion that, for decades, the Department has 
    accepted widespread industry non-compliance with the attendance 
    requirements. For these reasons, AmeriGas's petition for 
    reconsideration of RSPA's position regarding the Sec. 177.834(i) 
    attendance requirements is denied.
    1. RSPA's Position Is Consistent With the Regulatory History and Plain 
    Language of the Attendance Requirements in Sec. 177.834(i)
        AmeriGas argues in favor of an industry interpretation that 
    compliance with Sec. 177.834(i) can be achieved by having a single 
    operator remain in proximity to, and maintain an unobstructed view of, 
    any part of the delivery hose.
        The position that RSPA has taken with regard to the meaning of the 
    attendance requirements in 49 CFR 177.834(i) is not only consistent 
    with the plain language of the regulation but the regulatory history of 
    the regulation as well. Section 177.834(i) states:
    * * * * *
        (2) Unloading. A motor carrier who transports hazardous materials 
    by a cargo tank must ensure that the cargo tank is attended by a 
    qualified person at all times during unloading. . . .
        (3) A person ``attends'' the loading or unloading of a cargo tank 
    if, throughout the process, he is awake, has an unobstructed view of 
    the cargo tank, and is within 7.62 meters (25 feet) of the cargo tank.
    * * * * *
        (5) A delivery hose, when attached to the cargo tank, is considered 
    a part of the vehicle (Emphasis added.)
        RSPA's position consistently has been that the plain language of 
    Sec. 177.834(i) requires an attendant to maintain an unobstructed view 
    of the cargo tank and be within 25 feet of the cargo tank during the 
    unloading process.1 Contrary to AmeriGas's assertion, the 
    term ``cargo tank'' means the cargo tank itself and does not mean the 
    hose or CTMV. The language of Sec. 177.834(i)(5) plainly states that 
    the hose is part of the vehicle not the cargo tank.
    ---------------------------------------------------------------------------
    
        \1\ RSPA's position is supported by National Fire Protection 
    Association publication ``Standard for the Storage and Handling of 
    Liquefied Compressed Gases'' (NFPA 58), reported as adopted by 49 of 
    50 states. Section 4-2.3.3 requires, during unloading into storage 
    containers, that ``the shutoff valves on both the truck and the 
    container are readily accessible.''
    ---------------------------------------------------------------------------
    
        AmeriGas contends that there is support for industry's 
    interpretation of the Sec. 177.834(i)(3) requirements in the regulatory 
    history of these requirements. Specifically, AmeriGas relies on 
    language that appeared in a republication of 49 CFR Parts 71-90 by the 
    Interstate Commerce Commission (ICC) on December 29, 1964 (29 FR 
    18652). (The ICC regulated hazardous materials transportation by 
    highway and rail prior to 1967, the year the Department of 
    Transportation (DOT) was established). The regulatory text AmeriGas 
    relies on reads, ``Under no circumstances shall a tank motor vehicle be 
    left unattended during the loading or unloading process. For the 
    purpose of this part, the delivery hose, when attached to the motor 
    vehicle, shall be deemed a part thereof.'' (December 29, 1964; 29 FR 
    18801). RSPA believes this regulatory language makes it clear that a 
    CTMV operator must attend the CTMV and any delivery hose attached to 
    the motor vehicle
    
    [[Page 65191]]
    
    during loading and unloading. The intent of this provision was to 
    ensure that the operator took responsibility for the entire delivery 
    system which, for purposes of Part 77, included not only the motor 
    vehicle itself but also the delivery hose when attached to the motor 
    vehicle. However, the 1964 language in Sec. 77.834(i) was not specific 
    as to what actions constituted ``attendance.''
        Realizing that the word ``attendance'' was vague and that there was 
    industry confusion regarding what was required under the attendance 
    regulation, the Hazardous Materials Regulations Board (the Board), the 
    predecessor to RSPA's Office of the Associate Administrator for 
    Hazardous Materials Safety, initiated a rulemaking in Docket HM-110 to 
    clarify the attendance requirement. Language in the notice of proposed 
    rulemaking (NPRM) and the final rule in Docket HM-110 serves as the 
    basis for RSPA's interpretation of the current attendance requirement. 
    Specifically, in the preamble to the HM-110 NPRM, the Board stated:
    
        The Board has found that several dangerous incidents have 
    occurred during the loading or unloading of tank motor vehicles 
    which could have been avoided, if there had been someone near the 
    cargo tank to take corrective action or precautionary action. The 
    Board feels that there may be some confusion as to the intent of the 
    term ``attendance'' as it is used in Sec. 177.834(i). (Emphasis 
    added).
    
    38 FR 22901, August 27, 1973.
        Based on this concern, the Board proposed to revise the regulation 
    to include a requirement that an operator remain within 25 feet of the 
    cargo tank motor vehicle. The Board also proposed to delete the 
    limiting language ``for the purpose of this part'' from the hose 
    provision of the attendance requirements, thereby making the delivery 
    hose part of the tank motor vehicle not only for loading and unloading 
    purposes, but for other regulatory purposes as well (e.g., incident 
    reporting). Specifically, the Board proposed to revise the attendance 
    requirements in Sec. 177.834(i) to state:
    
        (1) A tank motor vehicle is attended when the person in charge 
    of the vehicle is awake and not in a sleeper berth, and is within 25 
    feet of the tank motor vehicle and has it within his unobstructed 
    field of view. . . . (3) The delivery hose, when attached to the 
    tank motor vehicle, is a part of the vehicle.
    
    Id. at 22902.
        In its January 11, 1973 comments to the Board's proposed revision 
    to Sec. 177.834(i), the National LP-Gas Association (NLPGA) (now NPGA) 
    proposed to revise the language to reinsert the limiting language ``for 
    the purpose of this part'' with regard to the hose provision of the 
    attendance requirements. Specifically, the NLPGA proposed to revise 
    Sec. 177.834(i)(3) to read ``For the purposes of this part the delivery 
    hose, when attached to the tank motor vehicle, is a part of the 
    vehicle.'' In explaining the proposed reinsertion of limiting words 
    ``for the purposes of this part,'' the NLPGA stated: ``We have no 
    objection to a requirement that the motor vehicle operator or motor 
    vehicle attendant be expected to attend the unloading hose as well as 
    the vehicle since in most cases he will provide the hose and will have 
    connected it to the unloading equipment. We don't feel the delivery 
    hose should be considered as a part of the motor vehicle.'' (Emphasis 
    added). Industry's comments on the HM-110 NPRM indicate that industry 
    fully understood that the Board proposed to require an attendant to 
    remain within 25 feet of the cargo tank motor vehicle and hose, and 
    maintain an unobstructed view of the cargo tank motor vehicle and hose. 
    It is apparent from the NLPGA's comments to the proposed changes to 
    Sec. 177.834(i) that it understood the Board's concerns and its intent.
        In the HM-110 final rule, the language that currently appears at 
    Sec. 177.834(i)(3), other than the addition of metric conversion of 25 
    feet, was adopted by the Board. Section 177.834(i)(3) currently reads, 
    ``A person `attends' the loading or unloading of a cargo tank if, 
    throughout the process, he is awake, has an unobstructed view of the 
    cargo tank, and is within 7.62 meters (25 feet) of the cargo tank.'' 
    Section 177.834(i)(5) currently reads, ``A delivery hose, when attached 
    to the cargo tank, is considered a part of the vehicle.'' In the final 
    rule, the Board adopted the language in Sec. 177.834(i)(3) that refers 
    to the ``cargo tank'' and not the ``tank motor vehicle,'' as proposed 
    in the NPRM. The language in Sec. 177.834(i)(5), however, continues to 
    refer to the hose as part of the vehicle. The final rule requires a 
    qualified person attending the loading or unloading of a cargo tank to 
    remain within 25 feet of the cargo tank, maintain an unobstructed view 
    of the cargo tank, and to attend the hose to the same extent that the 
    qualified person attends to the cargo tank motor vehicle under the HMR.
        AmeriGas also cites Shell Oil Company's October 26, 1973 comments 
    to the Board's proposed revision of the attendance requirements in 
    Docket HM-110 as support for its interpretation of the attendance 
    requirements and evidence that the agency was aware of the industry's 
    interpretation of the attendance requirements. Specifically, AmeriGas 
    points to Shell Oil's comment that ``Section 177.834(i)(1) requiring an 
    attendant within 25 feet of the tank motor vehicle or its hose is over 
    restrictive in cases where tight fill connections are used which are 
    now in the majority.'' (Emphasis added.) AmeriGas places great weight 
    on the fact that Shell used the word ``or'' rather than ``and'' to 
    describe the proposed requirements. AmeriGas states that the word 
    ``or'' put DOT on notice that the proposed language was being 
    interpreted to allow an operator to comply with the attendance 
    requirements by remaining within 25 feet of any part of the hose and 
    maintaining an unobstructed view of any part of the hose.
        AmeriGas, however, did not recognize or discuss the next sentence 
    in Shell's comments which reads, ``This restriction prohibits 
    performance of other duties and would unnecessarily increase delivery 
    costs.'' (Emphasis added). AmeriGas's interpretation of the attendance 
    requirements would allow an operator to be within 25 feet of and have 
    an unobstructed view of, any part of the CTMV including, any part of 
    its hose. Under AmeriGas's interpretation, there is virtually no 
    restriction on an operator's ability to perform other duties--an 
    operator can be virtually anywhere between the cargo tank motor vehicle 
    and the receiving tank--and a single operator can always satisfy the 
    industry interpretation of the attendance requirements. The preceding 
    regulatory history indicates that the Board intended to restrict the 
    movement of the person unloading a cargo tank by requiring the operator 
    to remain within 25 feet of the cargo tank and maintain an unobstructed 
    view of the cargo tank, resulting in a limitation on the attendant's 
    ability to perform other duties or activities. The type of 
    precautionary action the Board contemplated when it initiated HM-110 
    cannot be taken if a cargo tank attendant is more than 25 feet away 
    from the cargo tank, out of sight behind a building or other 
    obstruction, or both. This sentence indicates that Shell understood 
    that the Board was proposing new restrictions on unloading operations.
        RSPA squarely rejected industry's interpretation of the attendance 
    requirements during public meetings and workshops, in written 
    correspondence,2 and in the preamble to
    
    [[Page 65192]]
    
    the August 18, 1997 final rule.3 Specifically, the preamble 
    to the final rule states:
    
        \2\ See October 3, 1997 letter to Barton Day, Esq., counsel for 
    Ferrellgas, L.P., Suburban Propane, L.P., AmeriGas Propane L.P., 
    Agway Petroleum Corporation, Cornerstone Propane Partners, L.P., and 
    National Propane, L.P. (item no. 188 in RSPA docket 97-2133).
        \3\ Because of industry's concerns about the attendance 
    requirements, RSPA indicated in a June 9, 1997 notice [62 FR 31363] 
    that it would initiate a new rulemaking to review and possibly 
    revise the attendance and other regulatory requirements (see Docket 
    No. RSPA-97-2718).
    ---------------------------------------------------------------------------
    
        RSPA rejects the industry's interpretation of the long-standing 
    operator attendance rules in Sec. 177.834(i)(3) that a single 
    operator satisfies requirements for an unobstructed view of the 
    cargo tank, and is within 25 feet of the cargo tank, merely by being 
    in proximity to, and having an unobstructed view of, any part of the 
    delivery hose, which may be 100 feet or more away from the cargo 
    tank motor vehicle, during the unloading (transfer) operation. The 
    rule clearly requires an operator be in a position from which the 
    earliest signs of problems that may occur during the unloading 
    operation are readily detectable, thereby permitting an operator to 
    promptly take corrective measures, including moving the cargo tank, 
    actuating the remote means of automatic closure of the internal 
    self-closing stop valve, or other action, as appropriate. RSPA 
    contends the rule requires that an operator always be within 25 feet 
    of the cargo tank. Simply being within 25 feet of any one of the 
    cargo tank motor vehicle's appurtenances or auxiliary equipment does 
    not constitute compliance.
    
    62 FR at 44044.
        Because RSPA's position is consistent with the regulatory history 
    and plain language of 49 CFR 177.834(i), petitioner's request that RSPA 
    withdraw its interpretation is denied.
    2. Additional Notice and Comment Are Not Required Under the APA.
        AmeriGas alleges that RSPA's ``new interpretation'' was announced 
    without notice or opportunity to comment, in violation of the APA.
        Section 553 of the APA requires that Federal agencies give the 
    public an opportunity to participate in the rulemaking process by 
    giving notice, in the Federal Register, of either the terms or 
    substance of a proposed rule or a description of the subjects and 
    issues involved, and an opportunity to submit written data, views, or 
    arguments. As discussed above, the Board realized that the word 
    ``attendance'' was vague, as used in the original ICC attendance 
    regulations, and that there was industry confusion regarding what was 
    required. Consequently the Board issued an NPRM, in docket HM-110, 
    proposing to clarify the attendance requirements. In issuing the NPRM, 
    the Board specifically noted that there had been several dangerous 
    incidents during the loading or unloading of cargo tank motor vehicles 
    that the Board felt could have been avoided had someone been near the 
    cargo tank to take corrective or precautionary action.
        The Board's clearly specified reasons for undertaking the HM-110 
    rulemaking, in conjunction with the proposed regulatory language, 
    NLPGA's and Shell Oil's comments on that language, and the language of 
    the final regulatory requirements all demonstrate that: (1) the public 
    was given notice of the Board's intent to require an operator to be 
    near the cargo tank during unloading, and an opportunity to comment; 
    and (2) RSPA's position on the Sec. 177.834(i) attendance requirement 
    is long-standing and reflects industry understanding of the 
    requirements at the time they were proposed and adopted. Therefore, 
    RSPA's statements concerning the attendance requirements in 
    Sec. 177.834(i) do not in any way change the regulations or constitute 
    rulemaking. Consequently, further notice and comment under the APA is 
    not necessary.
    3. DOT Was Not Aware of Widespread Non-Compliance.
        AmeriGas claims that in the decades before--and 22 years since--the 
    attendance requirements in Sec. 177.834(i) were adopted, small CTMVs 
    typically carried delivery hoses of 100 feet or more in length and were 
    attended during at least a substantial portion of the unloading process 
    from the position of the customer tank. AmeriGas states that these 
    vehicles have operated openly and have been inspected by DOT officials 
    on hundreds of occasions over the years without any suggestion that the 
    routine operation of these vehicles under the industry's interpretation 
    of Sec. 177.834(i)(3) was improper. AmeriGas thus asserts that DOT has 
    accepted for decades without question industry's long-standing practice 
    of not remaining within 25 feet of the cargo tank and not maintaining 
    an unobstructed view of it.
        Although, FHWA inspectors occasionally inspect small CTMVs at 
    roadside inspection facilities, they do not inspect the hose to 
    determine its length as part of their routine inspection procedures. 
    Neither the HMR nor the Federal Motor Carrier Safety Regulations, 49 
    U.S.C. Parts 350-399, restrict hose length. Additionally, neither FHWA 
    nor RSPA inspectors routinely inspect small CTMV unloading operations. 
    Thus, the Department was not aware that small CTMV deliveries of 
    propane were being made in violation of the HMR. The fact that FHWA 
    inspectors may have observed small CTMVs with hose lengths in excess of 
    100 feet does not support the argument that DOT knew that deliveries 
    were being made in violation of the HMR.
        The National Fire Protection Association (NFPA) publication 
    ``Standard for the Storage and Handling of Liquefied Compressed Gases'' 
    (NFPA 58) reported by NFPA as adopted by 49 of 50 states (with Texas 
    preparing to adopt NFPA 58 next year), has unloading requirements that 
    are consistent with and provide support to the HMR requirement that a 
    qualified person maintain an unobstructed view of the cargo tank, and 
    be in a position to promptly effect emergency procedures should there 
    be a line separation or other problem requiring immediate attention. 
    Specifically, at Section 4-2.1.1, NFPA 58 states:
    
        Transfer operations shall be conducted by qualified personnel 
    meeting the provisions of Section 1-5. At least one qualified person 
    shall remain in attendance at the transfer operation from the time 
    connections are made until the transfer is completed, shutoff valves 
    are closed, and lines are disconnected. (Emphasis added).
    
    In addition, Section 4-2.3.3 of NFPA-58 requires:
    
        Cargo vehicles (see Section 6-3) unloading into storage 
    containers shall be at least 10 feet (3.0 m) from the container and 
    so positioned that the shutoff valves on both the truck and the 
    container are readily accessible. (Emphasis added).
    
        The fourth edition of the LP Gases Handbook, published by the NFPA 
    interprets Section 4-2.3.3 as follows: ``* * * The unloading cargo 
    vehicle should be a distance from the container receiving the product 
    so that if something happens at either point, the other will not be 
    involved to the extent that it would be if it were in close proximity. 
    Also, it is important to have the cargo vehicle so located that it is 
    easy to get to the valves on both the truck and the container so that 
    they can quickly be shut off if there is an emergency need to do so. * 
    * * '' 4 NFPA recognizes the importance of attending both 
    the receiving tank and the cargo tank. RSPA believes that both warrant 
    attention during unloading and that it is important to position these 
    tanks so that this safety objective is achievable.
    ---------------------------------------------------------------------------
    
        \4\ Theodore C. Lemoff, ed., LP-GASES Handbook, 4th ed. (Quincy: 
    National Fire Protection Association, 1995), p. 307.
    ---------------------------------------------------------------------------
    
        The importance of having a qualified person in a position to 
    promptly effect closure of the internal valve and to shut down all 
    motive and auxiliary power has been re-affirmed by two recent unloading 
    incidents that resulted in the death of one operator and injury to
    
    [[Page 65193]]
    
    another.5 These incidents did not involve the separation of 
    hose or piping, which emergency discharge control system requirements 
    are meant to address, but were the result of equipment failures, which 
    the attendance requirements in Sec. 177.834(i) are meant to address. 
    The CTMV was the suspected source of ignition in both of these 
    incidents. Based on initial reports, had a qualified person been in 
    attendance within 25 feet of the CTMV, he would have had a better 
    chance of closing the internal self-closing stop valve prior to 
    ignition.
    ---------------------------------------------------------------------------
    
        \5\ Initial reports from the Fire Marshall of Burke County, 
    North Carolina indicate that on September 23, 1997, in Morganton, 
    North Carolina, a Piedmont Natural Gas operator was at the receiving 
    tank (approximately 80 feet from the cargo tank motor vehicle) when 
    the hose nozzle became clogged with a foreign object believed to be 
    part of the meter, thus preventing the operator from closing the 
    nozzle when the customer tank became full. Consequently, the 
    receiving tank overfilled and propane continued to flow from the 
    hose at full pressure when the operator disconnected the hose from 
    the receiving tank. The operator began to approach the cargo tank 
    motor vehicle in order to manually shut the internal self-closing 
    stop valve, but there was an explosion and fire before he could take 
    emergency action. The operator received second-and third-degree 
    burns over most of his body and died shortly thereafter.
        On June 6, 1997, in Fayetteville, North Carolina, an AmeriGas 
    operator stopped product transfer and was in the process of 
    disconnecting the transfer hose from the receiving tank when he 
    observed white fog escaping from under the truck. He immediately 
    dropped the transfer hose and ran toward the truck (approximately 60 
    feet) to activate the engine kill switch and the emergency internal 
    self-closing stop valve. When he was within 10 to 12 feet of the 
    truck, the escaped gas vapors ignited, causing second degree burns 
    to the operator's face and right thigh.
    ---------------------------------------------------------------------------
    
        Therefore, based on the above information, RSPA denies that part of 
    AmeriGas's petition for reconsideration concerning the attendance 
    requirements. The attendance requirement is intended to address a 
    number of potentially serious threats to safety that may arise during 
    the course of unloading, including failure of a parking brake to 
    prevent movement of a motor vehicle; equipment failures (e.g., pump 
    leaks and leaks at a hose reel); and entry into the vicinity of the 
    motor vehicle by persons who are carrying smoking materials. In all 
    such instances, the qualified person attending the unloading operation 
    must be aware of potential and actual threats to safety and be prepared 
    to implement emergency procedures intended to minimize or eliminate 
    those threats.
    
    C. Need for Additional Operational Controls
    
        AmeriGas states that RSPA's central basis for the interim 
    requirements imposed under the August rule is that there is a need to 
    address safety concerns that exist due to the inability of the 
    emergency discharge control system currently in service on ``bobtail 
    vehicles'' in compressed gas service to function in accordance with the 
    HMR as specified under Sec. 178.337-11(a)(1)(i). The petitioner then 
    states that the record does not demonstrate the need for new 
    requirements because the record does not include even a single 
    documented incident involving the failure of the emergency discharge 
    control system on a bobtail vehicle. Further, the petitioner states 
    that the risk of such an event is extraordinarily remote and that there 
    is no safety threat sufficient to warrant the imposition of burdensome 
    interim operator attendance requirements for bobtails. Finally, the 
    petitioner claims that RSPA's decision to impose burdensome interim 
    operator attendance requirements for small CTMVs reflects a disregard 
    of the evidence before it and arbitrarily fails to consider less 
    burdensome regulatory alternatives.
        In response, RSPA's underlying purpose of alternative operational 
    controls adopted in the current requirements is to assure that persons 
    who are dependent upon propane, anhydrous ammonia, and other liquefied 
    compressed gases continue to receive those essential materials in a 
    manner that does not impose unacceptable threats to public health and 
    safety. The challenge was to develop rules for approximately 25,000 
    pump-equipped cargo tank motor vehicles (estimated to comprise the 
    universe of specification MC-330, MC-331, and related non-specification 
    cargo tanks) that industry determined may not conform to the long-
    standing requirements in Sec. 178.337-11(a)(1)(i) for an emergency 
    discharge control system (see emergency exemption applications filed by 
    Mississippi Tank, National Tank Truck Carriers, NPGA and TFI; December 
    1996).
        In developing the temporary alternative requirements, RSPA first 
    determined there must be an effective means of providing for prompt 
    closure of the internal self-closing stop valve under emergency 
    conditions until industry could develop a system that provides a level 
    of safety equal to that provided by Sec. 178.337-11. The risks posed by 
    an uncontrolled release of propane from a cargo tank motor vehicle are 
    so great that, while RSPA sought to minimize the cost of compliance 
    with the alternative requirements, safety was RSPA's primary concern. 
    Additional training and hose testing requirements adopted in Sec. 171.5 
    may reduce the risks of a release, but such measures do not provide a 
    means of stopping the flow of propane once a release occurs.
        The petitioner relies on a small number of incidents cited in the 
    public docket to support its contention that the safety concern with 
    regard to small CTMVs is minuscule. However, RSPA notes that: (1) 
    industry is not required to report to DOT the occurrence of propane 
    incidents or accidents that occur in intrastate commerce--which 
    encompasses the vast majority of small CTMV deliveries; and (2) the 
    small number of incidents in the record are not representative of the 
    entire universe of incidents of which RSPA is aware. Federal hazardous 
    materials transportation law at 49 U.S.C. 5103 directs the Secretary of 
    Transportation to prescribe regulations for the safe transportation of 
    a hazardous material when the Secretary determines that transporting a 
    material in commerce in a particular amount and form may pose an 
    unreasonable risk to health and safety or property. In developing 
    safety regulations, RSPA must consider potential hazards posed by a 
    material and may not base its regulatory decisions solely on the number 
    of reported incidents.
        For the reasons discussed above, RSPA denies this element of the 
    petitioner's request for reconsideration of the final rule.
    
    D. March 1, 1999 Expiration Date of the Temporary Final Rule 
    Requirements
    
        AmeriGas states that the legal effect of the expiration clause in 
    the final rule is to require operators of small CTMVs to have in place 
    passive emergency discharge control systems that will meet RSPA's 
    requirements under Sec. 178.337-11(a)(1)(i) by March 1, 1999. AmeriGas 
    requests that the expiration date specified in Sec. 171.5(c) be 
    stricken pending completion of the rulemaking proceeding under Docket 
    RSPA-97-2718 (HM-225A) that addresses long-term compliance issues.
        On August 18, 1997, RSPA published an advance notice of proposed 
    rulemaking (ANPRM) in Docket HM-225A (62 FR 44059) requesting comments 
    regarding jurisdiction, emergency discharge controls, qualification and 
    use of delivery hoses, and attendance requirements. The questions posed 
    in the ANPRM are indicative of the range of options RSPA is 
    considering, this includes various retrofit schedules for installation 
    of new equipment. RSPA is mindful of industry's concerns and will take 
    them into consideration in formulating a long-term compliance plan 
    under HM-225A. Additionally, affected parties may choose to install 
    systems that meet the
    
    [[Page 65194]]
    
    current requirements in Sec. 178.337-11(a)(1)(i). For these reasons, 
    RSPA denies AmeriGas's request for reconsideration of that part of the 
    final rule concerning the expiration date of Sec. 171.5.
    
    IV. Rulemaking Analyses and Notices
    
    A. Executive Order 12866 and DOT Regulatory Policies and Procedures
    
        This final rule is not considered a significant regulatory action 
    under section 3(f) of Executive Order 12866 and was not reviewed by the 
    Office of Management and Budget. This rule is not considered 
    significant under the regulatory policies and procedures of the 
    Department of Transportation (44 FR 11034; February 26, 1979). This 
    rule revises a safety standard for verifying the integrity of transfer 
    hoses on cargo tank motor vehicles in liquefied compressed gas service 
    and makes other minor, non-substantive changes.
        The final rule published on August 18, 1997, was a significant 
    regulatory action under section 3(f) of Executive Order 12866 and was 
    reviewed by the Office of Management and Budget. The rule also was 
    considered significant under the Regulatory Policies and Procedures of 
    the Department of Transportation (44 FR 11034).
        RSPA did not prepare a regulatory evaluation for this final rule 
    addressing the issue of revising the transfer hose pressure 
    requirement. However, a final regulatory evaluation was prepared in 
    support of the final rule published on August 18, 1997. The final 
    regulatory evaluation is available for review in the public docket.
    
    B. Executive Order 12612
    
        This final rule has been analyzed in accordance with the principles 
    and criteria contained in Executive Order 12612 (``Federalism''). The 
    Federal hazardous materials transportation law, 49 U.S.C. 5101-5127, 
    contains an express preemption provision (49 U.S.C. 5125(b)) that 
    preempts State, local, and Indian tribe requirements on certain covered 
    subjects. Covered subjects are:
        (1) The designation, description, and classification of hazardous 
    materials;
        (2) The packing, repacking, handling, labeling, marking, and 
    placarding of hazardous materials;
        (3) The preparation, execution, and use of shipping documents 
    related to hazardous materials and requirements related to the number, 
    contents, and placement of those documents;
        (4) The written notification, recording, and reporting of the 
    unintentional release in transportation of hazardous material; or
        (5) The design, manufacture, fabrication, marking, maintenance, 
    recondition, repair, or testing of a packaging or container 
    represented, marked, certified, or sold as qualified for use in 
    transporting hazardous material.
        This rule addresses covered subject item (5) above and preempts 
    State, local, and Indian tribe requirements not meeting the 
    ``substantively the same'' standard. Federal hazardous materials 
    transportation law provides at Sec. 5125(b)(2) that, if DOT issues a 
    regulation concerning any of the covered subjects, DOT 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. RSPA has determined that the 
    effective date of Federal preemption for these requirements will be 
    March 10, 1996. Thus, RSPA lacks discretion in this area, and 
    preparation of a federalism assessment is not warranted.
    
    C. Regulatory Flexibility Act
    
        The Regulatory Flexibility Act (Act), as amended, 5 U.S.C. 601-612, 
    directs agencies to consider the potential impact of regulations on 
    small business and other small entities. The Act, however, applies only 
    to rules for which an agency is required to publish a notice of 
    proposed rulemaking pursuant to Sec. 553 of the Administrative 
    Procedure Act (APA), 5 U.S.C. 553. See 5 U.S.C. 603(a) and 604(a). 
    Because of the emergency nature of the final rule published on August 
    18, 1997, RSPA was authorized under sections 553(b)(B) and 553(d)(3) of 
    the APA to forego notice and comment and to issue the final rule with 
    an immediate effective date. Nevertheless, RSPA was concerned about the 
    effect the final rule would have on small businesses and, in preparing 
    preliminary and final regulatory evaluations under Executive Order 
    12866, analyzed the impact of the interim final rule and final rule on 
    all affected parties, including small businesses. Consequently, RSPA is 
    not required under the Act to do a regulatory flexibility analysis for 
    this final rule.
    
    D. Unfunded Mandates Reform Act
    
        This rule does not impose unfunded mandates under the Unfunded 
    Mandates Reform Act of 1995. It does not result in costs of $100 
    million or more to either State, local, or tribal governments, in the 
    aggregate, or to the private sector, and is the least burdensome 
    alternative that achieves the objective of the rule.
    
    E. Paperwork Reduction Act
    
        This rule does not impose any new information collection burdens. 
    The information collection and recordkeeping requirements contained in 
    the final rule were submitted for renewal to the Office of Management 
    and Budget (OMB) under the provisions of the Paperwork Reduction Act of 
    1995. The requirement has been approved under OMB Control Number 2137-
    0595.
    
    F. Regulation Identifier Number (RIN)
    
        A regulation identifier number (RIN) is assigned to each regulatory 
    action listed in the Unified Agenda of Federal Regulations. The 
    Regulatory Information Service Center publishes the Unified Agenda in 
    April and October of each year. The RIN number contained in the heading 
    of this document can be used to cross-reference this action with the 
    Unified Agenda.
    
    List of Subjects in 49 CFR Part 171
    
        Exports, Hazardous materials transportation, Hazardous waste, 
    Imports, Reporting and recordkeeping requirements.

        (i) Before initiating each transfer from a cargo tank motor vehicle 
    to a receiving system, the person performing the function shall 
    determine that each component of the discharge system (including hose) 
    is of sound quality and free of leaks and that connections are secure. 
    This determination shall be made after the pressure in the discharge 
    system has reached no less than equilibrium with the pressure in the 
    cargo tank.
    * * * * *
        (iii) * * *
        (B) A qualified person positioned within arm's reach of a 
    mechanical means of closure of the internal self-
    
    [[Page 65195]]
    
    closing stop valve at all times the internal self-closing stop valve is 
    open; except, that person may be away from the mechanical means only 
    for the short duration necessary to engage or disengage the motor 
    vehicle power take-off or other mechanical, electrical, or hydraulic 
    means used to energize the pump and other components of the cargo tank 
    motor vehicle's discharge system; or
        (C) * * *
        (3) Is awake throughout the unloading process, and has an

    Sec. 171.5  [Amended]
    
        3. In addition, in Sec. 171.5 the following changes are made:
        a. In paragraph (a) introductory text, in the first sentence, 
    ``ruptured or'' is removed.
        b. In paragraph (a)(1)(ii), in the third sentence, ``and 
    equipment'' is removed.
        c. In paragraph (c), the date ``March 1, 1999'' is revised to read
