Cargo Tank Motor Vehicles in Liquefied Compressed Gas Service
OMB Control No. 2137-0595
(Expiration Date: July 31, 2023)
Introduction
This is to request the Office of Management and Budget’s (OMB) 3-year renewal for the information collection titled, “Cargo Tank Motor Vehicles in Liquefied Compressed Gas Service,” [OMB Control No. 2137-05951] that is currently due to expire on July 31, 2023. The requirements for this information collection originated from a December 29, 1964, final rule [29 FR 18743], which established the regulations for liquefied compressed gas (LPG) service in cargo tank motor vehicles.
Part A. Justification
Circumstances that make collection of information necessary.
This is a request for renewal without change of an information collection approved under [OMB Control No. 2137-0595] regarding cargo tank motor vehicles in Liquified Propane Gas (LPG) service. These information collection and recordkeeping requirements pertain to the manufacture, certification, inspection, repair, maintenance, and operation of Department of Transportation (DOT) specification MC 330, MC 331, and certain non-specification cargo tank motor vehicles used to transport liquefied compressed gases. This information collection supports the Departmental Strategic Goal for Safety.
As result of a serious unloading accidents in 1996, the Research and Special Programs Administration (RSPA), the Pipeline and Hazardous Materials Safety Administration’s (PHMSA) predecessor, learned that the emergency discharge control systems installed on cargo tank motor vehicles did not always function as required by the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) under all operating conditions. In 1997, RSPA issued a temporary regulation designed to permit cargo tank motor vehicles with non-complying emergency discharge control systems to continue to operate. This temporary regulation expired July 1, 1999, and a final rule2 under [Docket No. RSPA-97-2718, HM-225A] was issued May 24, 1999 [64 FR 28029] to replace the temporary regulation. This May 1999 final rule created a comprehensive safety program that combined measures to prevent unintentional releases of liquefied compressed gases during unloading operations with measures that will assure quick identification of releases and effective mitigation.
The final rule was developed through a negotiated rulemaking, during which stakeholders affected by the HMR worked together to analyze safety issues and identify potential solutions. The process gave these parties the opportunity to find creative solutions, improve the information data base for decisions, produce more accurate rules, enhance compliance, and reduce the likelihood of court challenges. The negotiated rulemaking committee included representatives from businesses that transport and deliver propane, anhydrous ammonia, and other liquefied compressed gases; manufacturers and operators of cargo tanks and vehicle components; and State and local public safety and emergency response agencies. The members agreed on the specifics of a proposed regulatory program, and both reviewed and concurred on the requirements of the new rule. After the evaluation of comments, RSPA issued a final rule based on the written agreement concurred on by the rulemaking committee.
The requirements necessitating an information collection under HM-225A included: (1) a requirement that cargo tank operators develop a comprehensive unloading operating procedure and carry it in each cargo tank motor vehicle; (2) new inspection, maintenance, marking, and testing requirements for cargo tank discharge systems, including delivery hose assemblies; and (3) new requirements for state-of-the-art emergency discharge control equipment on certain cargo tank motor vehicles transporting liquefied compressed gases that must be installed and certified by a Registered Inspector (RI). The rule provided a 2-year development and testing period of emergency discharge control technology. After 2 years, newly manufactured MC 331 cargo tank motor vehicles had to be equipped with emergency discharge control equipment that complies with certain performance standards; MC 330, MC 331, and certain non-specification cargo tank motor vehicles must be retrofitted at their first scheduled pressure test after the 2-year period.
The HM-225A final rule was intended to reduce the risk of an unintentional release during unloading, assure prompt identification and control of an unintentional release, and make the requirements easier to understand and with which to comply. The information collection and recordkeeping burdens from this rulemaking are imposed on motor carriers and on cargo tank motor vehicle manufacturers and repairers. Authority for the rulemaking and current regulations is the Federal hazardous materials transportation law, 49 U.S.C. 5101-5127.

Cargo tank motor vehicles in other than metered delivery service - design certification for automatic shutoff - § 173.315(n)(2)(ii)
This information collection is applicable to cargo tank motor vehicles in other than metered delivery service. The HMR requires that a cargo tank motor vehicle in other than metered delivery service must have a means to automatically shut off the flow of product without the need for human intervention within 20 seconds of an unintentional release caused by a complete separation of a liquid delivery hose (passive shut-down capability). This information collections requires that the design for the means to automatically shut off product flow be certified by a design certifying engineer. The certification must consider any specifications of the original component manufacturer and must explain how the passive means to shut off the flow of product operates. It must also outline the parameters (e.g., temperature, pressure, types of product) within which the passive means to shut off the flow of product is designed to operate. All components of the discharge system that are integral to the design must be included in the certification. A copy of the design certification must be provided to the owner of the cargo tank motor vehicle on which the equipment will be installed.
Cargo tank motor vehicles in other than metered delivery service - installation of the shutoff system by a Registered Inspector - § 173.315(n)(2)(iii)
This information collection is applicable to cargo tank motor vehicles in other than metered delivery service. The HMR requires that a cargo tank motor vehicle in other than metered delivery service must have a means to automatically shut off the flow of product without the need for human intervention within 20 seconds of an unintentional release caused by a complete separation of a liquid delivery hose (passive shut-down capability). This information collection requires that the installation must be performed under the supervision of a registered inspector (RI) unless the equipment is installed and removed as part of regular operation (e.g., a hose). The RI must certify that the equipment is installed and tested, if it is possible to do so without damaging the equipment, in accordance with the Design Certifying Engineer's certification. The RI must provide the certification to the owner of the cargo tank motor vehicle.
Cargo tank motor vehicles in metered delivery service - certification of remote control equipment by a Registered Inspector - § 173.315(n)(3)(ii)
This information collection is applicable to cargo tank motor vehicles in metered delivery service. This information collection requires that a cargo tank motor vehicle in meter delivered service must have an off-truck remote to close the internal self-closing stop valve and shut off all motive and auxiliary power equipment upon activation by a qualified person attending the unloading of the cargo tank motor vehicle (off-truck remote shut-off).
This information collection requires that the emergency discharge control equipment be installed under the supervision of a RI. Each wireless transmitter/receiver must be tested to demonstrate that it will close the internal self-closing stop valve and shut off all motive and auxiliary power equipment at 91.44 m (300 feet) under optimum conditions. Emergency discharge control equipment that does not employ a wireless transmitter/receiver must be tested to demonstrate its functioning at the maximum length of the delivery hose. This information collection requires that the RI certify that the remote-control equipment is installed in accordance with the original component manufacturer's specifications. The RI must provide the owner of the cargo tank motor vehicle with this certification.
Extent of automated information collection.
PHMSA has made this burden as simple as possible and requests information that is necessary to ensure safe operation. The information collection and recordkeeping requirements for operating procedures are general requirements that allow motor carriers to develop procedures that are best suited for their operations. The inspection, maintenance, and testing requirements for cargo tank discharge system components are additional certifications for current industry practices to ensure cargo tank motor vehicle safety. The Government Paperwork Elimination Act directs agencies to allow the option for electronic filing and recordkeeping by October 2003, when practicable. Records documenting inspection, testing, and maintenance programs may be kept electronically; however, they are not required to be submitted to PHMSA, so it is not applicable. PHMSA authorizes electronic filing and recordkeeping and additionally requires these records to be available upon request.
Efforts to identify duplication.
There is no duplication as the information is unique to specific situations. Each response is unique, and information derived from one may not be inferred to another. PHMSA has done its best effort to avoid duplication, while still ensuring that all requirements comply with application State requirements.
Efforts to minimize the burden on small businesses.
PHMSA periodically reviews the collection of this information to ensure that the amount of information needed is kept to a minimum.
Impact of less frequent collection of information.
Due to the hazards involved, it is not possible to lessen the frequency of information collection and recordkeeping. The development of an unloading operating procedure is a one-time process. Maintenance of a copy of the procedure on each cargo tank motor vehicle is a continuing requirement. Requirements for discharge system inspection and maintenance are continuing requirements that ensure that each cargo tank in liquefied compressed gas service is subject to a rigorous and systematic safety program. Certification of emergency discharge control equipment installation is a one-time requirement.
