ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: The Pipeline and Hazardous Materials Safety Administration is proposing to amend the Hazardous Materials Regulations to incorporate provisions contained in certain widely used or longstanding special permits that have general applicability and established safety records. Special permits allow a company or individual to package or ship a hazardous material in a manner that varies from the regulations provided that an equivalent level of safety is maintained. The revisions in this proposed rule are intended to provide wider access to the regulatory flexibility offered in special permits and eliminate the need for numerous renewal requests, thus reducing paperwork burdens and facilitating commerce while maintaining an appropriate level of safety. This rulemaking also proposes to respond to two petitions for rulemaking, P-1497 concerning the use of electronic shipping papers, and P-1567 concerning the removal of the Association of American Railroad's (AAR's) AAR-600 portable tank program for previously adopted standards that meet or exceed the AAR-600 requirements. DATES: Written comments should be submitted on or before October 17, 2011.#

SUPPLEMENTARY INFORMATION: I. Background II. Overview of Proposed Amendments III. Regulatory Analyses and Notices#

Passage 3The Pipeline and Hazardous Materials Safety Administration (PHMSA) is proposing to amend the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) to incorporate certain requirements based on existing special permits for transportation by railroad issued by PHMSA under 49 CFR part 107, subpart B (Sec. Sec. 107.101 to 107.127). A special permit sets forth alternative requirements (variances) to the requirements in the HMR by means that achieve a safety level that at a minimum corresponds to the safety level required under the regulations and is consistent with the public interest. Congress expressly authorized DOT to issue these variances in the Hazardous Materials Transportation Act of 1975. The HMR generally are performance-oriented regulations that provide the regulated community a certain amount of flexibility in meeting safety requirements. Even so, not every transportation situation can be anticipated and built into the regulations. Innovation is a strength of our economy, and the hazardous materials community is particularly strong at developing new materials and technologies as well as innovative ways of transporting materials. Special permits enable the hazardous materials industry to quickly, effectively, and safely integrate new products and technologies into the production and transportation streams. Thus, special permits provide a mechanism for testing new technologies, promoting increased transportation efficiency and productivity, and ensuring global competitiveness. A special permit must achieve at least an equivalent level of safety to that specified in the HMR. Implementation of new technologies and operational techniques can enhance safety because the authorized operations or activities may achieve a greater level of safety than currently required under the regulations. Special permits also reduce the volume and complexity of the HMR by addressing unique or infrequent transportation situations that would be difficult to accommodate in regulations intended for use by a wide range of shippers and carriers. PHMSA conducts ongoing reviews of special permits to identify widely used and longstanding special permits having general applicability with established safety records for adoption into regulations for broader applicability. To#

Passage 4obtain a special permit, interested parties must prepare and submit a detailed application that PHMSA reviews extensively. If granted and its use is needed after the expiration date assigned, the person authorized to use the special permit must submit an application to continue their use of it and undergo an extensive PHMSA renewal process. Converting these special permits into regulations reduces paperwork burdens and facilitates commerce while maintaining an acceptable level of safety. Additionally, adoption of special permits as rules of general applicability provides wider access to the benefits and regulatory flexibility of the provisions granted in the special permits. Factors that influence whether a specific special permit is a candidate for regulatory action include: the safety record for hazardous materials transported, or the transport operations conducted, under a special permit; the potential for broad application of a special permit; suitability of provisions in the special permit for incorporation into the HMR; rulemaking activity in related areas; and agency priorities. Special permits involving packaging used by a large number of persons-- such as those issued to many persons with party status or issued to a manufacturer as a ``manufacture, mark, and sell''--are potentially among the most suitable types of special permits for adoption into the HMR. Such special permits have broad applicability; moreover, many of them have been in effect for a number of years and have demonstrated safety records. Further, although we make every effort to stay as true as possible to the conditions prescribed in each special permit when converting it to proposed regulatory text, PHMSA recognizes that sometimes, due to existing regulations or historical interpretations, provisions in a special permit may require revision to convert them into regulations of general applicability. In addition, when converting special permits we often have to modify the language to describe documents and procedures that are authorized under the special permit but not specifically described in it or to modify the language to comply with requirements for proposed regulatory text prescribed by this agency, the Department of Transportation, and the Federal Register. This notice of proposed rulemaking (NPRM) proposes to incorporate seven (7) special permits that authorize tank car trans#

Passage 5portation operations not specifically permitted under the HMR. These special permits were initially issued to members of industry associations or similar organizations. They are DOT-SP: 1. 7616 2. 9388 3. 11184 4. 12095 5. 12905 6. 14333 7. 14622 These special permits have well-established safety records and, thus, are candidates for incorporation into the HMR. A few of the special permits in this NPRM have expired for various reasons, such as from delays that occur during the renewal process, or as a result of modifications to the HMR, packagings, processes, or other technologies that eliminate the need for the special permit. PHMSA has included them in this NPRM because both PHMSA and the Federal Railroad Administration (FRA) have determined these special permits also have well-established safety records and would benefit the regulated industry if incorporated into the HMR. Incorporating these special permits into the HMR would eliminate the need for over 250 current grantees to reapply for the renewal of these special permits every four years and for PHMSA to process the renewal applications. Incorporation of these special permits into the HMR also eliminates a significant paperwork burden for the recipient. Unless otherwise excepted by this agency, a copy of each special permit must be: maintained at each facility where a packaging is manufactured under a special permit, maintained at each facility where a package is offered or re-offered for transportation under a special permit, carried on board each cargo vessel or aircraft, and, in some cases, carried on board each transport vehicle when used to transport a hazardous material under a special permit. Two proposals PHMSA is addressing in this proposed rulemaking were also presented to PHMSA in petitions for rulemaking. A more detailed description of each is provided below.#

Passage 6The petition from the International Vessel Operators Hazardous Materials Association, Inc. (IVOHMA) (P-1497), dated March 15, 2007, is similar to relief authorized under DOT-SP 7616 in that it requests PHMSA allow shipping paper information required under 49 CFR Part 172, Subpart C (shipping papers) to be transmitted electronically by computer through use of electronic data interchange (EDI). The IVOHMA states ``differences in hazard communication or the interpretation of their application are a principle[sic] source of disharmony in intermodal and/or international transportation of [hazardous materials].'' The IVOHMA also states ``electronic data interchange has become a recognized method of efficient and accurate communication currently being used successfully throughout the industrialized world'' that permits ``immediate access to hazard communication by all those involved in the transportation infrastructure as well as by emergency responders equipped'' with this technology. Further, the IVOHMA states in its petition that the proposals it submitted were vetted with its staff and members and determined to be opportunities for regulatory amendment to promote efficiencies in the modal interchange of these containers in both domestic and international transportation. PHMSA and the FRA met with the IVOHMA, on January 17, 2007, to discuss several issues concerning the HMR and containerized hazardous materials cargo that the association and its members believe may be presenting operational difficulties, impediments, and obstacles to efficient and safe intermodal transportation. These issues included inconsistencies between the shipping paper requirements for each mode for documents that can be construed as meeting the HMR shipping paper requirements, ``such as work orders, dock receipts or train consists,'' and determining which shipping document is considered legally in control of the shipment. The IVOHMA also identified two problems associated with the train consist. The first problem is Sec. Sec. 174.24 and 174.26 do not require that the agency or person be identified that corresponds to the emergency response information telephone number on the document. The HMR requires this information on a shipping paper document under Sec. 172.604(b). The IVOHMA states ``valuable time is often lost'' while emergency responders using these telephone numbers or inspectors#

Passage 7checking their validity track down the correct individual and/or organization associated with a specific telephone number. The IVOHMA also states a similar problem occurs when international telephone numbers are offered as the emergency response telephone number that provides access from the United States to the emergency responder, and includes delays that occur obtaining a telephonic connection while using the international access codes. The second problem is the#

Passage 8emergency response telephone number needs to be accessible by all the persons associated with the transport of the shipment, such as those carriers trying to obtain information to respond to a shipboard emergency. To address these concerns, the IVOHMA submitted proposed regulatory language that would define the term ``interlining carrier'' in Sec. 171.8, establish requirements for ``interlining carrier documents'' in a new Sec. 172.206, and make several additional related revisions concerning shipping papers and emergency response information in Sec. Sec. 172.204(d), 172.604(a), and 174.26(b). Although the petition the IVOHMA submitted primarily concerned the transportation of containerized hazardous materials between railcars and vessels, the regulatory language the IVOHMA proposed would apply to interlining carriers in all modes. This rulemaking applies to rail transportation only. Therefore, PHMSA determined proposing regulations that apply to carriers in all modes would exceed the scope of this rulemaking. PHMSA considered revising the IVOHMA's proposals to limit them to rail transport only with the possibility of considering their application to other modes of transport in a future rulemaking. However, FRA determined the IVOHMA's proposals are not needed because the language in existing Sec. 174.24(a) applies to the transfer of all interlining documents. This section requires that each person accept a hazardous material for rail transportation or transport a hazardous material by rail only if that person has received a shipping paper for that material. If the material is excepted from the shipping paper requirements under the HMR, this section does not apply. PHMSA requests public comment not only on the proposals in this rulemaking, but on IVOHMA's suggestions not included in this rulemaking and on the possible effects EDI may have on distributing hazardous materials shipping paper information if its use is permitted in all modes of transport. Based on the comments received, PHMSA may consider the use of EDI in other modes of transport in a future rulemaking.#

Passage 9PHMSA adopted standards for portable tanks in container-on-flat-car (COFC) or trailer-on-flat-car (TOFC) service under Sec. 174.63 and other sections of the HMR that meet or exceed the AAR-600 requirements. The petition from the Gold Tank Inspection Service, Inc. (P-1567), requests that PHMSA discontinue the AAR-600 program and amend Sec. 174.63(c) to remove the requirement that portable tanks in COFC or TOFC service comply with the standard ``AAR-600'' of the Association of American Railroad's (AAR's) Specification for Tank Cars, entitled ``Specifications for the Acceptability of Tank Containers,'' because: (1) The current HMR regulations exceed the AAR 600 requirements; (2) after January 1, 2003, all the specifications for original portable tank construction listed in the AAR 600 standard are not allowed to be built except DOT Specification 60 and International standard 1496-3 portable tanks, which are already covered under Sec. Sec. 178.255 and 178.274, respectively, of the HMR; and (3) after January 1, 2010, the AAR 600 standard will no longer be needed since, in accordance with Sec. 171.14, all portable tanks will have to meet or exceed the AAR 600 requirements and AAR 600 does not cover portable tank requirements. In a May 20, 2009 letter of clarification PHMSA issued to Robert E. Fronczak, Assistant Vice President, Environment and Hazardous Materials, Association of American Railroads, under Reference No. 09- 0125, PHMSA states ``most of the portable tanks listed in the AAR-600 standard are prohibited from new construction, although they may remain in service provided they continue to meet the applicable standard,'' and that ``we intend to propose a revision to Sec. 174.63(c) as soon as practicable.'' The changes Mr. Fronczak described have effectively made the HMR's reference to the AAR-600 standard outdated. Therefore, PHMSA proposes to revise Sec. 173.63(c) to remove its reference to the AAR 600 standard and to require that portable tanks transported in COFC or TOFC service must conform to all HMR requirements applicable to portable tanks in this type of service.#

Passage 10In this NPRM, PHMSA is proposing to incorporate into the HMR provisions that: (a) Establish an alternative tank car qualification program; (b) permit the electronic transmission of shipping paper information; (c) permit straight threads in the clean out and/or inspection port openings of a DOT Specification 110A500W multi-unit tank car tank; (d) permit alternative start-to-discharge pressure requirements for certain DOT Specification 105J500W tank cars containing chlorine; (e) permit alternative pressure relief requirements for pressure relief devices for DOT Specification 105J300W tank cars containing certain flammable liquids; (f) permit certain DOT and AAR specification tank cars with stainless steel identification plates to have their specification and other required information stamped on the identification plate instead of the tank car head provided certain requirements are met; (g) permit liquefied anhydrous ammonia gas to be measured by a metering device when loaded into a tank car as an alternative to measuring the cars by weight; (h) revise Sec. 179.13(b) to require that rail tank cars with a gross weight that exceeds 263,000 but not 286,000 pounds containing poisonous-by- inhalation (PIH) materials must be approved for use by the Federal Railroad Administration's (FRA's) Associate Administrator for Railroad Safety; and (i) eliminate use of the AAR 600 program concerning the FRA's approval of bulk packagings in COFC and TOFC service that is incorporated into Sec. 174.63(c)(2). PHMSA invites comment on the potential costs and safety benefits associated with the proposals in this NPRM, including any information that may be used in a cost-benefit safety analysis. Each proposal is discussed in greater detail in the following preamble sections. A. Alternative Tank Car Qualification Program#

Passage 11The FRA established the Alternative Tank Car Qualification Program, also known as TCQ-1, in 1998 in collaboration with the railroad industry and PHMSA under Special Permit DOT-SP 12095. The TCQ-1 program serves as a minimally acceptable framework for owners to qualify their DOT specification and non-specification tank cars and components using requirements in place of those prescribed in 49 CFR Part 180. The TCQ-1 program permits owners to develop tank car inspection requirements specific to their construction and use, provided the FRA has determined the new methods are as safe or safer than those prescribed in the HMR. FRA determined the new program is successful and its use has dramatically increased since its inception. In fact, FRA and PHMSA have determined the industry's use of the TCQ-1 program is so complete that it essentially is the only tank car inspection standard used today. Currently, 559 parties are operating under TCQ-1. PHMSA and FRA are not aware of any incidents that have occurred as a result of the issuance of special permits for the tank car qualification program. PHMSA and FRA believe incorporating Special Permit DOT-SP 12095 into the HMR will provide an equivalent level of safety for the qualification of both specification and non-specification rail tank cars, and will reduce the administrative burden of reapplying for this special permit. Therefore, in this NPRM, PHMSA and FRA are proposing to incorporate Special Permit DOT-SP 12095 into the HMR. This proposal pertains to: marking and stamping; adding new definitions pertaining to tank cars; adding qualifications for tank car inspections and tests; revising the requirements for tank car repairs, alterations, conversions, and modifications; clarifying recordkeeping requirements; and listing hazardous and other materials corrosive to tanks or service equipment. The following table summarizes the proposed changes:#

Paragraph (b)(5)........ This TCQ-1 paragraph is omitted but language is used from existing Sec. 180.507(b)(5). 4............. 180.509................. Paragraph (a)(4)........ Added last sentence to ameliorate a concern from tank car owners that modifications have been made to their cars without their knowledge; minor edits. Paragraph (b)(4)........ Replaced ``probable cause'' with the wording ``objectively reasonable and articulable belief'' because the former is a term of art in criminal law and is also used in FRA drug and alcohol regulations. The intent of Sec. 180.509(b)(4) is to create a standard less strict than that of an emergency order, but rigorous enough to compel a tank car owner to reinspect and repair, if necessary, tank cars considered potential hazards irrespective of their periodic test and inspection requirements. Paragraph (c)(1)........ Minor edits. Paragraph (d)........... Minor edits. Paragraph (d)(2)........ Added last sentence for clarity. Paragraph (d)(3)........ Added ``Corrosion'' as specific element for inspection. Paragraph (d)(5)........ To insure inclusiveness, added ``all closures'' as substitute for specific item names. Paragraph (d)(6)........ Dropped ``operability'' test of excess flow valves because it is not a practical test and a successful result might damage the excess valve seat and preclude seating in a future event. Paragraph (e)(1)........ Replace ``high-stressed structural elements'' with the simpler words ``structural elements.''#

Passage 14Paragraph (f)(1)........ Added the responsibility of the tank car owner for clarity. Paragraph (f)(4)........ Added a general prohibition against operating overly thin tank cars; this responsibility is changed from putting it solely on tank car owners who often have no control over the day to day movements of their tank cars. Paragraph (g)........... Minor edits; removes the language that implies only a ``qualified individual'' could find a thin tank car and invoke the restrictions in this paragraph. Paragraph (h)........... No change. Paragraph (i)........... Minor edits. Paragraph (j)...........

Paragraph (l)........... Minor edits. Paragraph (m)........... After 12/2010 the requirements of paragraph (m) should have been fulfilled. There may be late tank cars or tank cars with extended alternate inspection intervals; therefore, this provision will be retained for an additional 5-10 years. 5............. 180.511................. ........................ Added minor edits; included those in Part 180, Subpart F, to capture requirements for qualifying service equipment. 6............. 180.513................. Paragraph (a)........... Reworded to encompass the entire AAR Tank Car Manual rather than certain appendices. Paragraph (b)........... Added for clarification and as a reminder that tank car or component owners are responsible for verifying compliance with the owner's maintenance instructions. Paragraph (c)........... Is the same language as existing paragraph (b) from DOT-SP 12095. The last sentence was added for clarification. 7............. 180.515................. Paragraph (a)........... Added last sentence to clarify the primacy of dates marked in Appendix C of the AAR Tank Car Manual. 8............. 180.517................. ........................ Revised to clarify that marking or retaining the specification on the tank, either after initial construction in paragraph (a) or subsequent qualification in paragraph (b), is the ``representation'' of ``qualification'' defined in Sec. 180.503. ----------------------------------------------------------------------------------------------------------------#

Passage 15Additional provisions from Special Permit DOT-SP 12095 as proposed will be in Sec. Sec. 179.201-10, 179.220-25, and 180.501, and 180.503, 180.507, 180.509, 180.511, 180.513, 180.515, 180.517, and Appendix D of part 180. B. Telephone and Electronic Data Interchange Shipping Papers#

Passage 16Special Permit DOT-SP 7616 permits the transmission of shipping paper information by telephone and electronic data interchange (EDI). Special Permit DOT-SP 7616 is currently used by 626 parties. Prior to this special permit, shippers entered information on shipping papers by hand, typewriter, or with the use of a computer and then transmitted these documents by hand, railroad agent, facsimile, or postal system to a train crew or rail yard. These methods were very time consuming. This shipping information would then be entered into the receiver's tracking system, a process that resulted in a large number of key entry errors for hazardous materials shipments. Starting in the 1960s, many companies began using in-house computer systems and networks to assist with preparing and tracking shipping information, but technological limitations often prevented or restricted one company's system from communicating with another's. Rail companies and shippers attempting to address these issues and find solutions formed the Transportation Data Coordination Committee (TDCC) in 1968, and started publishing standards on EDI in 1975. In the mid- 1970's, the U.S. Department of Transportation (USDOT) issued Exemption DOT-E 7616 to permit railroad companies to ``certify'' their shipping papers for hazardous materials by permitting the shipper to leave a ``voice'' message stating that a hazardous materials shipment loaded on a railcar was being offered for transportation. Eventually, the exemption was revised to allow an ``electronic'' shipping document to be faxed and later transmitted electronically from computer to computer. Today, EDI standards are used worldwide for most industries that rely on electronic data transfer of information, such as banks, medical institutions, and shipping companies outside of railroad- related businesses. In consultation with USDOT, the TDCC evolved, and the EDI standards were published as guidelines on electronic data standards for the transportation industry. These guidelines established format codes and protocols for communicating and verifying the accuracy of electronic information, including hazardous materials information on a shipping paper, for hazardous materials shippers and carriers. Currently, the Accredited Standards ``X12'' Committee (ACS) of the American National Standards Institute (ANSI) creates standards specifically for EDI. Indu#

Passage 17stry organizations take these standards and modify them to fit the types of electronic transmissions and/or transactions needed by each industry. This is what is done in the railway industry. As a result, there is no one specific standard that includes all the electronic transmissions permitted as EDI. Special Permit DOT-SP 7616 allows a carrier to accept shipping paper information via telephone (i.e., voice communications) for hazardous material shipments that have been transported by railroad, and authorizes several variations in the certification requirement when this information is transmitted telephonically or through EDI. The Federal Aviation Administration and Federal Motor Carrier Safety Administration have informed PHMSA and FRA that some#

Passage 18inconsistencies exist when these standards are applied between the different transportation modes. Therefore, in this NPRM, PHMSA and FRA are proposing to incorporate into the HMR the provisions for EDI prescribed in Special Permit DOT-SP 7616 and requested in Petition No. P-1497 for any hazardous materials shipment transported by rail only. This will exclude, for example, the use of voice communications as an authorized method for carriers to accept hazardous materials shipping paper information for transporting these shipments by aircraft or motor vehicle. Further, PHMSA and FRA are proposing to allow a signature in the signature block of an EDI form to represent completion of the shipper's certification prescribed under Sec. 172.204. Users of EDI may wish to consult the ANSI's ACS X12 Committee for guidance on EDI transmissions and transactions for electronic shipping documents, along with any other guidance developed on this subject by the Department's agencies, such as the FRA. PHMSA and FRA are not aware of any incidents that have occurred as a result of the issuance of Special Permit DOT-SP 7616. PHMSA and FRA have also determined the overall effect of the special permit has improved the timely and accurate receipt of hazardous materials information, thereby improving safety. As mentioned earlier in this preamble, the IVOHMA also requested through a petition for rulemaking (P-1497) that PHMSA revise the HMR to include the transmission of shipping documents through EDI. PHMSA and FRA acknowledge that hazardous materials shipping document information is routinely transmitted by computer but no provision in the HMR specifically addresses this. PHMSA and FRA also note that the use of EDI to transmit this information does not eliminate the requirement for the printed copy of a shipping paper to accompany a hazardous materials shipment. PHMSA and FRA specifically request comments on the costs and safety benefits associated with these proposals, as well as the possible effects and/or modifications needed to permit EDI to transmit successfully the shipping paper information for hazardous materials in all transportation modes. The provisions for Special Permit DOT-SP 7616 and Petition No. P- 1497 are proposed in Sec. Sec. 172.201, 172.202, 172.204, and 172.604. The changes that IVOHMA proposed for Sec. 174.24 are also located in Sec. 172.202; therefore, they a#

Passage 19re not needed in Sec. 174.24 and we are not proposing to revise that section. C. Straight Threads on Multi-Unit Tank Cars#

Passage 20Special Permit DOT-SP 14333 authorizes the manufacture, marking, sale and use of a non-DOT specification tank car conforming to all the regulations applicable to the DOT Specification 110A500W multi-unit tank car tank, except that the tank must be equipped with straight threads in the clean-out/inspection port openings instead of the National Gas Taper Threads. Four parties currently use this special permit. This special permit also permits retrofitting. Section 179.300- 13(b) requires that taper threads must be used on the valve opening. In the safety equivalency evaluation for Special Permit DOT-SP 14333, PHMSA and FRA determined that straight threads on the clean-out/ inspection port opening would provide an equivalent level of safety. Tapered threads are designed to provide a seal when torqued. The seal is a result of the compression of the male and female threads. Because they compress, there is an inevitable degree of deformation. This deformation decreases the likelihood that a proper seal can be obtained upon subsequent applications. Straight threads are used on connections where a gasket is compressed to create a seal. Therefore, a seal can be obtained by repeated application as long as the gasket has not degraded. The clean-out/inspection port openings are used repeatedly and introduce an opportunity for leaks. The straight threads on these openings help to minimize leaking. Special Permit DOT-SP 14333 limits the use of the straight threads opening to certain high-hazard Division 2.3 (poisonous gas), Division 6.1 (poisonous), and Class 8 (corrosive) hazardous materials, as well as those materials authorized to be transported in DOT Specification 110A500W multi-unit tank car tanks. However, PHMSA and FRA believe straight threads in inspection ports can be used for all hazardous materials authorized to be transported in DOT Specification 110A multi-unit tank car tanks and are proposing this action in this NPRM. PHMSA and FRA are not aware of any incidents that have occurred as a result of the issuance of this special permit, and believe these provisions, if adopted, will provide an adequate level of safety. Therefore, PHMSA and FRA are proposing to incorporate Special Permit DOT-SP 14333 into the HMR and further allowing straight threads in inspection ports to be used for all hazardous materials authorized to be transported in DOT Specification 110A#

Passage 21multi-unit tank car tanks. The provisions for this special permit are proposed in Sec. 179.300-13(b) for DOT Specification 110A multi-unit tank cars only. D. Alternative Start-to-Discharge Pressure Requirements for Tank Cars Containing Chlorine#

Passage 22Special Permit DOT-SP 14622 authorizes the transportation of certain DOT Specification 105J500W tank cars containing chlorine that have start-to-discharge settings that do not meet the regulatory requirements for pressure relief devices. Three parties currently use this special permit. In its original application for this special permit, Occidental Chemical Corporation (OxyChem) requested relief from Sec. 179.15(b) to allow tank cars in chlorine service to be equipped with combination pressure relief valves (PRV) with a set pressure of 360 pounds per square inch (psi) rather than the required set pressure of 356 psi. OxyChem justified its request based on its history of operating tank cars safely in a manner similar to what it was requesting. OxyChem also based its request on the HMR's regulatory history prior to the final rule issued under Docket No. HM-216, effective on October 1, 1996 (61 FR 28666; 61 FR 38642; 61 FR 50252), which permitted DOT Specification 105J500W tank cars used to transport chlorine to be equipped with a PRV with a set pressure of 356 psi. The FRA conducted an evaluation of the level of safety provided by the terms and allowances of Special Permit DOT-SP 14622. As part of this evaluation, FRA staff contacted the Chlorine Institute, which represents all of the companies that are a party to this special permit. The Chlorine Institute reported it has not received a report of any incident related to the conditions allowed under Special Permit DOT-SP 14622. In addition, the Chlorine Institute found the PRV setting does not affect the standard start-to-discharge pressure that is the basis for the flow rating pressure. The flow rating pressure, in turn, is used to calculate the required PRV flow capacity. Therefore, the FRA finds the valve is sized appropriately for the required design conditions. The FRA has one safety concern related to Special Permit DOT-SP 14622. If the relief discs or pins burst or break within their tolerances, there is the potential that the valve will be exposed to the lading and its vapor for an extended period of time. A rupture disc or breaking pin is used in conjunction with a reclosing PRV to#

Passage 23provide a barrier between the valve and its components from the lading and the vapor of the lading, as exposure to these can lead to corrosion and ultimately the malfunctioning of the valve. Furthermore, the FRA believes it is important that combination PRVs are equipped with ``tell-tale devices'' located outboard (outside) of the rupture disc (or breaking pin) and inboard (inside) of the valve. When the disc or breaking pin is intact, the valve indicates no pressure. If the disc or pin has been compromised, the valve will show an elevated pressure. An operator inspecting the condition of the tell-tale device can determine if the rupture disc or breaking pin has been compromised. A rupture disc has a rated pressure burst-pressure tolerance of +/- 5 percent. A breaking pin has a rated pressure burst-pressure tolerance of +/- 10 percent (see ASME Section VIII, UG-126 Pressure Relief Valves). An evaluation of the special permit relative to both the rupture disc and breaking pin is provided in the following paragraph. Special Permit DOT-SP 14622 allows for the PRV to have a set pressure of 360 psi. The special permit allows the burst pressure of the relief device to be 96 percent of the start-to-discharge pressure rather than the required maximum of 95 percent. As stated earlier, the set pressure in SP-14622 is within the rated pressure burst tolerance of the rupture disc and rated pressure burst tolerance of the breaking pin described earlier in this paragraph. However, it is possible that a rupture disc could burst at the limit of its negative tolerance at 356 psi. In this case, the valve with a set pressure of 360 psi would be undetected and exposed to the lading or the vapor of the lading. While this sequence is possible, the negative effects to the valve are very limited. This can be demonstrated by reviewing the thermodynamic properties of chlorine and the time needed to increase the vapor pressure of the chlorine to the set pressure of the PRV. Based on the vapor pressure-temperature relationship of chlorine, the temperature of chlorine at a vapor pressure of 356 psi is approximately 165 [deg]F and its temperature at 360 psi is approximately 170 [deg]F. It is evident that as the temperature of chlorine increases, the vapor pressure of the chlorine also increases at a slightly faster rate. A pool fire represents the only scenario in which the temperature o#

Passage 24f chlorine in a tank could reach 165 [deg]F. In this scenario, the heat input is so great that the specific heat and heat of vaporization requirements would be met quickly and raise the temperature and the respective vapor pressure of the chlorine in the tank car to a level that would actuate the PRV, causing the PRV to function and vent the pressure in the tank. Under these hazardous conditions, corrosion of the PRV body and components are very minor considerations. Regarding the breaking pin, as stated earlier, the rated pressure tolerance is +/- 10 percent. Both the start-to-discharge pressure requested in Special Permit DOT-SP 14622 and required in the HMR are within the design tolerance of the breaking pin. As a result, neither poses a greater risk to the safe operation of the relief valve and tank car. Based on this analysis, PHMSA and FRA believe operation of a tank car under the terms of Special Permit DOT-SP 14622 provides a level of safety that is equivalent to that of a similar tank car operated under the HMR. Therefore, we propose to adopt this requirement into the HMR. The provisions for this special permit are proposed in Sec. 173.314(k)(2). E. Alternative Pressure Relief Requirements for Pressure Relief Devices for Tank Cars Containing Certain Flammable Liquid Materials#

Passage 25Special Permit DOT-SP 11184 authorized the transportation in commerce of certain Class 3 materials in DOT Specification 105J300W tank cars with a pressure relief device rated at 25 percent of tank test pressure. The commodities authorized under this special permit were typically shipped in general purpose (GP) tank cars (e.g., DOT Specification 111A100W). In 1996, PHMSA, then known as the Research and Special Programs Administration, added Sec. 179.15 to the HMR in a final rule it issued on June 5, 1996, under Docket No. HM-216 (61 FR 28666). In paragraph (b)(2)(i) of that section, the agency added the requirement that reclosing pressure relief devices in tank cars, other than DOT Class 106, 107, 110, and 113 tank cars, may not have a start- to-discharge pressure setting lower than 5.17 Bar (75 psig) or higher than 33 percent of the minimum tank burst pressure, a range that included the 25 percent of tank test pressure relief device rating required in paragraph 2.a of DOT-SP 11184. As a result, DOT-SP 11184 was no longer needed and PHMSA let it expire. When it was active, 21 parties used this special permit. PHMSA and FRA are discussing DOT-SP 11184 in this NPRM to clarify that the rulemaking action issued under Docket No. HM-216 eliminated the need for this special permit, and to emphasize that this revision improved safety in two ways. First, it lowered the start-to-discharge pressure for the PRV, which allowed the car to vent at lower pressures when in an overheated condition--such as a pool fire. Commodities listed in this special permit when exposed to extreme heat and pressure will undergo rapid polymerization that could result in an energetic and catastrophic failure of the tank car. Second, the DOT Specification 105J300W tank car's thicker shell and head will result in the tank car having a significantly greater survivability than its GP tank car counterparts. PHMSA and FRA have determined these revisions to the HMR are performing satisfactorily; therefore, we are expiring this special permit. PHMSA and FRA are not aware of any incidents that have occurred as a result of the issuance of Special Permit DOT-SP 11184. F. Transportation in Commerce of Certain Tank Cars With Identification Plates in Lieu of Stamping the Tank Car Heads#

Passage 26Special Permit DOT-SP 12905 permits certain DOT and AAR specification tank cars with stainless steel identification plates to have their specification and other required information stamped on the identification plate instead of the tank car heads if certain requirements are met. The AAR requires all cars built after December 31, 2003, to be equipped with identification plates as specified in Appendix C, paragraph 4.0. Additionally, for several years manufacturers have built portable tanks and cargo tanks with a data plate containing all pertinent information related to the construction of the tank. Incorporating Special Permit DOT-SP 12905 into the HMR will bring the railcar data identification in line with the AAR standards and the portable tank and cargo tank industries. Also, FRA acknowledges that stamping this information into the tank car wall may introduce a defect into its steel. Although minimal, stamping results in a stress concentration in the area of the stamp. Use of a data plate would eliminate this defect. Currently, 22 parties use this special permit. PHMSA and FRA are not aware of any incidents that have occurred as a result of the issuance of Special Permit DOT-SP 12905. PHMSA and FRA believe that incorporating this special permit into the HMR will provide an equivalent level of safety for the qualification of both specification and non-specification rail tank cars. AAR tank cars are required to have an identification plate after December 31, 2011. Therefore, PHMSA and FRA are proposing to amend the HMR to require tank cars to have a stamped identification plate one year after the publication date of the final rule issued as a result of this proposed rulemaking. We propose to adopt this requirement into new section Sec. 179.24 and existing sections Sec. Sec. 179.100-20, 179.200-24, 179.201-10, and 179.220-25 of the HMR. G. Measuring Liquefied Gases Loaded into a Tank Car With Metering Devices as an Alternative to Measuring These Cars by Weight#

Passage 27Special Permit DOT-SP 9388 authorizes the transportation in commerce of DOT specification tank cars that have ``UN 1005, Ammonia, anhydrous, 2.2 (non-flammable gas)'' liquefied gas measured by a metering device when loaded into the tank. Although anhydrous ammonia is defined as meeting both a Division 2.3 (poisonous gas) and Class 8 (corrosive) hazard class under the United Nations Recommendations on the Transport of Dangerous Goods, International Civil Aviation Organization Technical Instructions on the Transport of Dangerous Goods by Air, and International Maritime Dangerous Goods Code, the HMR permits anhydrous ammonia to be defined as meeting the Division 2.2 hazard class in domestic transportation only. For increased safety, DOT-SP 9388 requires that each of these tank cars must be loaded and unloaded using procedures that specify at a minimum: Employee safety equipment; proper signage; set brakes and installed wheel blocks; an examination of the tank and/or jacket, its undercarriage assembly, hoses, connections, valves, and accessories inside the loading dome for damage; recording of defects; certification of inspection and completion of loading and/or unloading procedures, as well as other recordkeeping requirements. PHMSA and FRA propose to incorporate these requirements in new Sec. 173.314(e)(2)(i). Also, DOT-SP 9388 requires that one out of every 10 tanks cars must have the metered gauge verified with the tank car gauge in accordance with certain procedures to determine the current capacity of the car. PHMSA and FRA propose to incorporate these procedures in new Sec. 173.314(e)(2)(ii). Although Special Permit DOT-SP 9388 is currently expired, 28 parties previously used it. Since the original issuance of DOT-SP 9388, flow meter technology is much more accurate and reliable. PHMSA and FRA are not aware of any incidents that have occurred as a result of the issuance of this special permit. PHMSA and FRA believe that incorporating this special permit into the HMR will provide an equivalent level of safety for the qualification of both specification and non-specification rail tank cars. Therefore, we propose to adopt this requirement, with the additions noted above, into Sec. 173.314(e) of the HMR. H. Approval for Gross Weight on Rail Tank Cars#

Passage 28Special Permits DOT-SP 11241, 11654, 11803, 12423, 12561, 12613, 12768, 12858, 12903, 13856, 13936, 14004, 14038, 14442, 14505, 14520, 14570, and 14619, allowed rail tank cars with a gross weight on rail that exceeded 263,000 pounds but not exceeding 286,000 pounds to be used to transport certain hazardous materials provided the tank car is approved by the FRA's Associate Administrator for Railroad Safety. PHMSA adopted these special permits, along with several others, in a final rule issued under Docket No. PHMSA-2009-0289 (HM-233A; 75 FR 27205, 5/14/2010) because they were widely used and had established safety records. However, the final rule erroneously omitted from Sec. 179.13(b) a provision to require FRA approval for those gross-weight- on-rail tank cars authorized to contain materials that are poisonous- by-inhalation. PHMSA is proposing to correct this omission in this rulemaking by revising Sec. 179.13(b) to add the FRA approval statement. I. Reference to the Association of American Railroads AAR 600 Program#

Passage 29The AAR Tank Car Committee and the AAR Hazardous Materials Committee have recommended the discontinuance of the AAR 600 program as incorporated in Sec. 174.63(c)(2). Currently, this program requires that a bulk packaging, including a portable tank, transported in COFC or TOFC service must conform to the conditions specified in Sec. 174.63 of the HMR. These regulations require approval by FRA's Associate Administrator for Railroad Safety, unless, among other things, the tank conforms to requirements in AAR 600 of the AAR Specifications for Tank Cars, ``Specifications for Acceptability of Tank Containers.'' In accordance with AAR 600, approval and registration of compliant portable tanks is required based on a determination that the tank meets all applicable standards and payment of a registration fee. Since incorporation of the AAR 600 standard into the HMR, PHMSA has adopted standards for portable tanks that meet or exceed the AAR 600 requirements. The AAR committees believe that the current HMR portable tank regulations have now exceeded the AAR 600 requirements and that all of the specifications for original construction listed in the AAR 600 Standard were not allowed to be built after January 1, 2003, except for the DOT Specification 60 and other United Nations (UN) portable tanks that are authorized in the HMR. As stated earlier in this rulemaking, PHMSA agreed with the AAR proposal in a letter dated May 20, 2009 and stated we would propose a revision to Sec. 174.63(c). As also discussed earlier in this preamble, PHMSA received a petition (P- 1567) dated July 9, 2010, from Gold Tank Inspection Services, Inc., requesting the removal of the reference to the AAR 600 program in Sec. 174.63 because the HMR now includes standards for portable tanks that meet or exceed AAR 600 requirements. Accordingly, in this NPRM, PHMSA is proposing to require that portable tanks transported in COFC or TOFC service must conform to all HMR requirements applicable to portable tanks. Consistent with this proposed revision, PHMSA is proposing to remove the reference in Sec. 171.7(a)(3) to Sec. 173.63 under the listing ``AAR Manual of Standards and Recommended Practices, Section C- Part III, Specifications for Tank Cars, Specification M-1002, (AAR Specifications for Tank Cars), December 2000.'' A. Statutory/Legal Authority for This Rulemaking#

Passage 30This NPRM is published under the authority of 49 U.S.C. 5103(b) which authorizes the Secretary to prescribe regulations for the safe transportation, including security, of hazardous material in intrastate, interstate, and foreign commerce. 49 U.S.C. 5117(a) authorizes the Secretary of Transportation to issue a special permit from a regulation prescribed in sections 5103(b), 5104, 5110, or 5112 of the Federal Hazardous Materials Transportation Law to a person transporting, or causing to be transported, hazardous material in a way that achieves a safety level at least equal to the safety level required under the law, or consistent with the public interest, if a required safety level does not exist. If adopted as proposed, the final rule would amend the regulations incorporating provisions from certain widely used and longstanding special permits that have established a history of safety and which may, therefore, be converted into the regulations for general use. B. Executive Order 12866, Executive Order 13563, and DOT Regulatory Policies and Procedures#

Passage 31This proposed rule is not considered a significant regulatory action under section 3(f) and was not reviewed by the Office of Management and Budget (OMB). The proposed rule is not considered a significant rule under the Regulatory Policies and Procedures order issued by the Department of Transportation [44 FR 11034]. Executive Orders 12866 (``Regulatory Planning and Review'') and 13563 (``Improving Regulation and Regulatory Review'') require agencies to regulate in the ``most cost-effective manner,'' to make a ``reasoned determination that the benefits of the intended regulation justify its costs,'' and to develop regulations that ``impose the least burden on society.'' In this notice, PHMSA proposes to amend the HMR by incorporating alternatives this agency has permitted under widely used and longstanding special permits with established safety records that we have determined meet the safety criteria for inclusion in the HMR. Incorporation of these special permits into regulations of general applicability will provide shippers and carriers with additional flexibility to comply with established safety requirements, thereby reducing transportation costs and increasing productivity. In addition, the proposals in this NPRM will reduce the paperwork burden on industry and this agency caused by continued renewals of special permits. The provisions of this proposed rule will promote the continued safe transportation of hazardous materials while reducing transportation costs for the industry and administrative costs for the agency. Therefore, the requirements of Executive Orders 12866 and 13563, and the DOT policies and procedures concerning these orders have been satisfied.#

Passage 32This proposed rule was analyzed in accordance with the principles and criteria contained in Executive Order 13132 (``Federalism''). This proposed rule would preempt state, local and Indian Tribe requirements but does not propose any regulation that has substantial direct effects on the states, the relationship between the national government and the states, or the distribution of power and responsibilities among the various levels of governments. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply. Federal hazardous material transportation law, 49 U.S.C. 5101, et seq., contains an express preemption provision (49 U.S.C. 5125(b)) preempting state, local and Indian Tribe requirements on certain covered subjects. Covered subjects are: (1) The designation, description, and classification of hazardous material; (2) The packing, repacking, handling, labeling, marking, and placarding of hazardous material; (3) The preparation, execution, and use of shipping documents related to hazardous material 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 designing, manufacturing, fabricating, marking, maintaining, reconditioning, repairing, or testing of a package, container or packaging component that is represented, marked, certified, or sold as qualified for use in transporting hazardous material in commerce. This proposed 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. PHMSA proposes the effective date of Federal preemption be 90 days from publication of a final rule in this matter in the Federal Register.#

Passage 33This proposed rule was analyzed in accordance with the principles and criteria contained in Executive Order 13175 (``Consultation and Coordination with Indian Tribal Governments''). Because this proposed rule does not have Tribal implications and does not impose substantial direct compliance costs on Indian Tribal governments, the funding and consultation requirements of Executive Order 13175 do not apply. E. Regulatory Flexibility Act, Executive Order 13272, and DOT Procedures and Policies The Regulatory Flexibility Act (5 U.S.C. 601-611) requires each agency to analyze regulations and assess their impact on small businesses and other small entities to determine whether the rule is expected to have a significant impact on a substantial number of small entities. The NPRM proposes to amend the HMR to incorporate provisions contained in seven widely used or longstanding railroad special permits that have an established safety record. Although many of the applicants may be small businesses or other small entities, PHMSA believes that the revisions in this proposed rule are intended to provide wider access to the regulatory flexibility offered in special permits and eliminate the need for numerous renewal requests, thus reducing paperwork burdens and facilitating commerce while maintaining an appropriate level of safety. Therefore, PHMSA certifies that the provisions of this NPRM would not have a significant economic impact on a substantial number of small entities. This proposed rule has been developed in accordance with Executive Order 13272 (``Proper Consideration of Small Entities in Agency Rulemaking'') and DOT's procedures and policies to promote compliance with the Regulatory Flexibility Act to ensure that potential impacts of draft rules on small entities are properly considered.#

Passage 34PHMSA has approved information collections under OMB Control Number 2137-0051, ``Rulemaking, Special Permits, and Preemption Requirements,'' OMB Control Number 2137-0557, ``Approvals for Hazardous Materials,'' and OMB Control Number 2137-0559, ``(Rail Carriers and Tank Car Requirements) Requirements for Rail Tank Cars--Transportation of Hazardous Materials by Rail. This NPRM may result in a decrease in the annual burden and costs under OMB Control Number 2137-0051 and an increase in the annual burden and costs under OMB Control Number 2137- 0557 and OMB Control Number 2137-0559 due to proposed changes to incorporate provisions contained in certain widely used or longstanding special permits that have an established safety record. Under the Paperwork Reduction Act of 1995, no person is required to respond to an information collection unless it has been approved by OMB and displays a valid OMB control number. Section 1320.8(d), title 5, Code of Federal Regulations requires that PHMSA provide interested members of the public and affected agencies an opportunity to comment on information and recordkeeping requests. This notice identifies a revised information collection request that PHMSA will submit to OMB for approval based on the requirements in this proposed rule. PHMSA has developed burden estimates to reflect changes in this proposed rule. PHMSA estimates that the information collection and recordkeeping burden as proposed in this rule is as follows: ------------------------------------------------------------------------ ------------------------------------------------------------------------ OMB Control No. 2137-0051: Decrease in Annual Number of Respondents..................... 255 Decrease in Annual Responses:................................ 255 Decrease in Annual Burden Hours.............................. 255 Decrease in Annual Burden Costs.............................. $9,500 ------------------------------------------------------------------------ ------------------------------------------------------------------------#

Passage 35------------------------------------------------------------------------ OMB Control No. 2137-0557: Increase in Annual Number of Respondents..................... 200 Increase in Annual Responses:................................ 200 Increase in Annual Burden Hours.............................. 50 Increase in Annual Burden Costs.............................. $1,100 ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------ OMB Control No. 2137-0559: Increase in Annual Number of Respondents................. 350 Increase in Annual Responses............................. 350 Increase in Annual Burden Hours.......................... 350 Increase in Annual Burden Costs.......................... $10,500 ------------------------------------------------------------------------ PHMSA specifically requests comments on these information collections and recordkeeping burdens associated with developing, implementing, and maintaining these requirements for approval under this proposed rule. Requests for a copy of this information collection should be directed to Deborah Boothe or Steven Andrews, Standards and Rulemaking Division, (PHH-10), Pipeline and Hazardous Materials Safety Administration, 1200 New Jersey Avenue, SE., Washington, DC 20590-0001, Telephone (202) 366-8553. Address written comments to the Dockets Unit as identified in the ADDRESSES section of this rulemaking. We must receive comments regarding information collection burdens prior to the close of the comment period identified in the DATES section of this rulemaking. In addition, you may submit comments specifically related to the information collection burden to the PHMSA Desk Officer, Office of Management and Budget, at fax number 202-395-6974. 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 contained in the heading of this document may be used to cross-reference this action with the Unified Agenda.#

Passage 36This proposed rule does not impose unfunded mandates under the Unfunded Mandates Reform Act of 1995. It does not result in costs of $141.3 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.#

Passage 37The National Environmental Policy Act of 1969 (NEPA), as amended (42 U.S.C. 4321-4347), and implementing regulations by the Council on Environmental Quality (40 CFR part 1500) require Federal agencies to consider the consequences of Federal actions and prepare a detailed statement on actions that significantly affect the quality of the human environment. The hazardous materials regulatory system is a risk management system that is prevention oriented and focused on identifying a hazard and reducing the probability and quantity of a hazardous materials release. This rulemaking is concerned with the transportation of hazardous materials by rail, but is prepared with the understanding that these materials are often transported by aircraft, vessel, and highway before or after they are transported by rail. The need for hazardous materials to support essential services means transportation of highly hazardous materials is unavoidable. However, these shipments frequently move through densely populated or environmentally sensitive areas where the consequences of an incident could be loss of life, serious injury, or significant environmental damage. The ecosystems that also could be affected by a hazardous materials release during transportation include atmospheric, aquatic, terrestrial, and vegetal resources (for example, wildlife habitats). The adverse environmental impacts associated with releases of most hazardous materials are short- term impacts that can be greatly reduced or eliminated through prompt clean-up of the incident scene. In this NPRM, we are requesting comments on the potential environmental impacts of the proposals. In all modes of transport, the potential for environmental damage or contamination exists when packages of hazardous materials are involved in transportation incidents. Most of the special permits considered in this rulemaking involve bulk packages of hazardous materials in DOT specification and non-specification tank cars. While the volume of hazardous material present in these packagings has the potential to be released into the environment during a transportation incident, these packagings are constructed to withstand greater forces during impact and are also equipped with safety relief devices and valves specifically designed to maintain the containment ability of the tank car. The purpose and need of this rulemaking is to incorpora#

Passage 38te widely used special permits or those with an established safety record into the HMR for universal use. More information about benefits of the proposed action can be found in the preamble (i.e., ``Overview of Proposed Amendments) to this rulemaking. The alternatives considered in the analysis include (1) the proposed action, that is, incorporation of the proposed special permits as amendments to the HMR; (2) incorporation of some subset of the proposed special permits (i.e., only some of the proposed special permits) as amendments to the HMR; and (3) the ``no action'' alternative, meaning that none of the proposed special permits would be incorporated into the HMR. PHMSA believes that the each of these alternatives would result in equal environmental risk and/or impact because special permits are intended to offer equivalent safety and environmental protection as the HMR. In considering the potential environmental impacts of the proposed action, PHMSA does not anticipate that the incorporation of the listed special permits will result in any significant impact on the human environment because the process through which special permits are issued requires the applicant to demonstrate that the alternative transportation method or packaging proposed provides an equivalent level of safety as that provided in the HMR. However, PHMSA welcomes and will consider and address comments about foreseeable environmental impacts or risk associated with the incorporation of any proposed special permit. The agencies and persons consulted in the development of this regulatory proposal include the International Vessel Operators Hazardous Materials Association, Inc.; Gold Tank Inspection Services, Inc.; Surface Deployment and Distribution Command (SDDC); Conrail; Agrium N.A.Wholesale Transportation Compliance; Koch Nitrogen Company; Columbiana Boiler Company; and subject matter expert staff in FRA and PHMSA. Given that this rulemaking proposes to amend the HMR to incorporate provisions contained in certain widely used or longstanding railroad special permits that have an established safety record, these proposed change in regulation would increase safety and environmental protections. There are no significant environmental impacts associated with this proposed rule.#

Passage 40Authority: 49 U.S.C. 5101-5128, 44701; 49 CFR 1.53. 5. In Sec. 172.201, revise paragraph (a)(2) and add paragraph (a)(5) to read as follows: Sec. 172.201 Preparation and retention of shipping papers.#

Passage 41(a) * * * (2) The required shipping description on a shipping paper and all copies of the shipping paper used for transportation purposes must be legible and printed (manually or mechanically) in English. * * * * * (5) Electronic shipping papers. For transportation by rail, a rail carrier may accept shipping paper information either telephonically (i.e., voice communications and facsimiles) or electronically (EDI) from an offeror of a hazardous materials shipment in accordance with the provisions in paragraphs (a)(5)(i) through (v) of this section. For the purposes of this section electronic data interchange (EDI) means the computer-to-computer exchange of business data in standard formats. In EDI, information is organized according to a specific format (electronic transmission protocol) agreed upon by the sender and receiver of this information, and transmitted through a computer transaction that requires no human intervention or retyping at either end of the transmission.

A tank car found with a thickness below the required minimum thickness after forming for its specification, as stated in part 179 of this subchapter, may continue in service if any reduction in the required minimum thickness is not more than that provided in the following table:#

Passage 61Allowable Shell Thickness Reductions ------------------------------------------------------------------------ Top shell and tank Marked tank test pressure head Bottom shell ------------------------------------------------------------------------ 60 psig =200 psig..................... 0.79 mm........... 0.79 mm 1/32 inch......... \1/32\-inch ------------------------------------------------------------------------ Note 1. A tank car owner may add an extra 1.58 mm (1/16 inch) to the values in the table for local reductions. Local reductions are those that do not exceed 20.32 linear centimeters (8 linear inches) measured at the longest diameter, and are separated from the other local reductions by at least 40.64 cm (16 inches). Note 2. Any reduction in the tank car shell thickness may not affect the structural strength of the tank car to the extent that the tank car no longer conforms to Section 6.2 of the AAR Specifications for Tank Cars (IBR, see Sec. 171.7 of this subchapter). Note 3. For DOT 115 class tank cars, shell thickness reductions apply only to the outer shell of the tank car. There is no shell or head thickness reduction authorized for the inner tank.#

Passage 62(h) Safety system inspections. Each tank car owner must ensure qualification of the tank car safety systems. However, inspections of foam or cork insulation systems are not required. (i) Lining and coating inspection and test. (1) At a minimum, the owner of a lining or coating applied to protect a tank used to transport a material that is corrosive or reactive to the tank must ensure accomplishment of an inspection adequate to detect defects or other conditions that could reduce the reliability of the tank. In addition, the owner of a lining of tank cars used to transport hazardous materials must ensure the lining complies with Sec. 173.24(b)(2) and (3) of this subchapter. (2) The owner of the lining or coating must establish and maintain a record of the service life of the lining or coating and commodity combination, that is, the specific hazardous materials that were loaded into a tank and the lining or coating in place at the time of loading. The owner of the lining or coating must use its knowledge of the service life of each lining or coating and commodity combination to establish an appropriate inspection interval for that lining or coating and commodity combination. This interval must not exceed eight (8) years, unless the lining or coating owner can establish, document, and show that the service history or scientific analysis of the lining or coating and commodity pairing supports a longer inspection interval. The owner must maintain at its principal place of business a written procedure for collecting and documenting the life of the lining or coating applied within the tank car. The lining or coating owner must provide this documentation, including inspection and test, repair, removal, and application procedures, to the FRA or car owner upon request. In addition, any person who offers a loaded tank car into transportation must provide commodity information to the car owner and the owner of the lining or coating upon request. (3) The owner of the lining or coating must provide the test method and acceptance criteria for the lining or coating to the tank car owner and to the person responsible for qualifying the lining or coating. The tank car facility inspecting and testing the lining or coating must follow the inspection and test requirements, including the acceptance requirements, established by the lining or coating owner. (j) Leakage pressure tes#

Passage 63t. Unless the design of the service equipment arrangement precludes it (e.g., there is no fitting to pressurize the tank), each owner of a tank car must ensure that the tank, service equipment, and closures installed, replaced, or reinstalled on the tank car are leak tested. The test may be conducted with the lading in the tank. When the test pressure exceeds the start- to-discharge or burst pressure of a pressure relief device, the device must be rendered inoperative. The written procedures and test method for leak testing must ensure for the sensitivity and reliability of the test method and for the serviceability of components to prevent premature failure. This section does not apply to facilities that remove closures for the sole purpose of loading or unloading the lading (e.g., blind flanges, pipe plugs, etc.). (k) Service equipment inspection and test. (1) Each tank car owner must ensure for the qualification of tank car service equipment at least once every ten (10) years. The tank car owner must analyze the service equipment inspection and test results for any given lading and, based on the analysis, adjust the inspection and test frequency to ensure that the design level of reliability and safety of the equipment is met. The owner must maintain at its principal place of business all supporting documentation used to make such analyses and inspection and test frequency adjustments. The supporting documentation must be made available to FRA or an authorized representative of the Department upon request. (2) Each tank car facility must qualify service equipment, including reclosing pressure relief devices and interior heater systems in accordance with Appendix D of the AAR Specifications for Tank Cars (IBR, see Sec. 171.7 of this subchapter). (l) Alternative inspection and test procedures. When approved by the#

Passage 64Associate Administrator for Railroad Safety, FRA, a tank car owner, or a lining or coating owner may use an alternative inspection and test procedure or interval based on a damage-tolerance analysis (that must include a determination of the probable locations and modes of damage due to fatigue, corrosion, and accidental damage), or based on a service reliability assessment (that must be supported by analysis of systematically collected data) in lieu of the other requirements of this section. (m) Qualification compliance date for tank cars. (1) After July 1, 2000, each tank car with a metal jacket or with a thermal protection system must have an inspection and test conforming to this section no later than the date the tank car requires a periodic hydrostatic pressure test (i.e., the marked due date on the tank car for the hydrostatic test). (2) For insulated or jacketed tank cars on a 20-year periodic hydrostatic pressure test interval (i.e., Class DOT 103W, 104W, 111A60W1, 111A100W1, and 111A100W3 tank cars), the next inspection and the test date is the midpoint between the compliance date in paragraph (m)(1) of this section and the remaining years until the tank would have had a hydrostatic pressure test. 26. In Sec. 180.511, revise the introductory text and paragraphs (d) and (g) and add paragraph (h) to read as follows: Sec. 180.511 Acceptable results of inspections and tests.#

Passage 65Provided it conforms to other applicable requirements of this subchapter, a tank car is qualified for use if it successfully passes the inspections and tests set forth below conducted in accordance with this subpart. A representation of that qualification must consist of marking the tank in accordance with Sec. 180.515. * * * * * (d) Safety system inspection. A tank car successfully passes the safety system inspection when each thermal protection system, tank head puncture resistance system, coupler vertical restraint system, and system used to protect discontinuities (e.g., breakage grooves on bottom outlets and protective housings) on the tank car conform to this subchapter and show no indication of a defect that may reduce reliability before the next inspection and test interval. * * * * * (g) Hydrostatic test. A Class 107 tank car, the inner tank of a Class 115 tank car, or a riveted tank car successfully passes the hydrostatic test when it shows no leakage, distortion, excessive permanent expansion, or other evidence of weakness that might render the tank car unsafe for transportation service. (h) Service equipment. A tank car successfully passes the service equipment inspection and test when this equipment equipment conforms to this subchapter and AAR Appendix D (IBR, see Sec. 171.7 of this subchapter) and shows no indication of a defect that may reduce reliability before the next inspection and test interval. 27. Revise Sec. 180.513 to read as follows: Sec. 180.513 Repairs, alterations, conversions, and modifications.#

Passage 66(a) To work on tank cars, a tank car facility must comply with the applicable requirements of this subpart, the AAR Specifications for Tank Cars (IBR, see Sec. 171.7 of this subchapter), and the owner's requirements. (b) An owner of a tank car or component is responsible for ensuring that each tank car facility complies with the owner's maintenance program by conducting periodic analyses and surveillance activities. (c) Unless the exterior tank car shell or interior tank car jacket has a protective coating, after a repair that requires the complete removal of the tank car jacket, the exterior tank car shell and the interior tank car jacket must have a protective coating applied to prevent the deterioration of the tank shell and tank jacket. Previously applied coatings that still provide effective protection need not be covered over. (d) After repair, replacement, or qualification of tank car service equipment, the tank service equipment must successfully pass the leak test prescribed in Sec. 180.509(j). 28. Revise Sec. 180.515 to read as follows:#

Passage 67(a) When a tank car passes the required inspection and test with acceptable results, the tank car facility must mark the date of the inspection and test and the due date of the next inspection and test qualified on the tank car in accordance with Appendix C of the AAR Specifications for Tank Cars (IBR, see Sec. 171.7 of this subchapter). When a tank car facility performs multiple inspections and tests at the same time, one date may be used to satisfy the requirements of this section. One date also may be shown when multiple inspections and test have the same due date. Dates displayed on the ``consolidated stencil'' (see Appendix C of the AAR specifications for Tank Cars) take precedence over dates modified, and not stenciled, pursuant to interval adjustments for service equipment, linings, and granted alternative inspection intervals. (b) Converted DOT 105, 109, 112, 114, or 120 class tank cars must have the new specification and conversion date permanently marked in letters and figures at least 0.95 cm (0.375 inch) high on the outside of the manway nozzle or the edge of the manway nozzle flange on the left side of the car. The marking may have the last numeral of the specification number omitted (e.g., ``DOT 111A100W'' instead of ``DOT 111A100W1''). (c) When qualified within six months of installation and protected from deterioration, the test date marking of a reclosing pressure relief device is the installation date on the tank car. 29. In Sec. 180.517, revise paragraph (a), paragraph (b) introductory text, and paragraphs (b)(3). (4), and (7), and add paragraph (b)(8) to read as follows: Sec. 180.517 Reporting and record retention requirements.#

Passage 68(a) Certification and representation. Each owner of a specification tank car must retain the certificate of construction (AAR Form 4-2) and related papers certifying that the manufacture of the specification tank car identified in the documents is in accordance with the applicable specification. The builder's signature on the certificate of construction, and the marking of the tank car with the tank specification is the representation that all of the appropriate inspections and tests were successfully performed to qualify the tank for use. The owner must retain the documents throughout the period of ownership of the specification tank car and for one year thereafter. Upon a change of ownership, the requirements in Section 1.3.15 of the AAR Specifications for Tank Cars (IBR, see Sec. 171.7 of this subchapter) apply. The builder of the car or a facility performing work on the car may retain copies of relevant records. (b) Inspection and test reporting. Each tank car that is inspected and tested as specified in Sec. 180.509 must have a written report, in English, prepared according to this paragraph. For qualification inspections and tests performed after initial service, marking the tank car with the specification (or retaining the specification marking on the tank) is the representation that all of the appropriate inspections and tests were successfully performed to qualify the car for continued use. The report may be created and retained electronically, but, upon request by FRA for a copy of the report, it must be made available in common readable form. The owner must retain a copy of the inspection and test reports until successfully completing the next inspection and test of the same type. The inspection and test report must include the following: * * * * * (3) Tank car reporting mark and number; (4) Tank car specification; * * * * * (7) The name and address of the tank car facility and the name and signature of inspector; and (8) The unique code (station stencil) identifying the facility. 30. Add Appendix D to Part 180 to read as follows: Appendix D to Part 180--Hazardous Materials Corrosive to Tanks or Service Equipment#

Passage 69This list contains materials identified either by proper shipping name in 49 CFR 172.101 or shipped under an ``n.o.s.'' shipping description that, under certain conditions, can corrode carbon steel tanks or service equipment at a rate that will reduce the design level of reliability and safety of the tank or equipment to an unsafe level before the next qualification. Materials identified on this list are considered corrosive to the tank or service equipment. While every effort was made to identify materials deemed corrosive to the tank or service equipment, owners and operators are cautioned that this list may not be inclusive. Tank car owners and operators are reminded of their duty to ensure that no in-service tank will deteriorate below the specified minimum thickness requirements in this subchapter. See Sec. 180.509(f)(3). In addition, FRA states a tank car owner must designate an interior coating or lining appropriately based on their knowledge of the chemical and not rely simply on this list. Regarding future thickness tests, this list may also be modified based on an analysis of the test results by the car owner, the Department of Transportation, or the Association of American Railroads' Tank Car Committee.
