The Panel recognizes that these comments are submitted after the close of the comment period, but would like the opportunity to go on the record in support of the proposed changes to Section 172.330(a)(1), Specifically, the Panel maintains that the proposed changes to the tank car marking requirements in proposed Section 172.330 (a) (1) (ii) are appropriate to adequately inform transportation personnel and emergency responders about the tank car contents. By adjusting the marking requirements to allow the use of the "key words of the proper shipping name" or the proper shipping name or common name, the objective of the DOT'S hazardous materials regulations will be attained, without compromising safety. This amendment will enable shippers whose proper shipping name is amended to avoid the costs of remarking the tank cars provided the marking contains the key words of the proper shipping name. The Panel appreciates the opportunity to submit these comments. Please call me at 703-741-5637, if you have any questions or need additional information. Sincerely^ CC; Beth Romo James H.

This action is necessary to update the regulations and to respond to petitions for rulemaking. The intended effect of these regulatory changes is to improve safety and reduce costs to offerors and transporters of hazardous materials.

Special Provision B5 would be revised to authorize use of tank cars, constructed from other than aluminum plate, for ammonium nitrate fertilizer. Consistent with proposed changes to Part 171 Section 171.7. Various American Society for Testing and Materials (ASTM) standards would be updated to reflect the most current version. Other ASTM. standards that no longer would be referenced in the proposed revision of $ 179.12 would be removed. tank car marking requirements discussed previously in conjunction with proposed changes to the Hazardous Materials Table, Special Provision B12 would be removed. The requirement to mark the proper shipping name or common name of a material on a tank car would be limited to certain materials that present a higher risk in Part 172 Section 172.101; The Hazardous Materials Table. In the Hazardous Materials Table, several entries would be revised based on petitions for rulemaking and agency initiative. Proposed revisions include: transportation, as proposed in $ 172.330. - Special Provisions B42, B65, B71, B72, B74, and B76 would be revised for clarity. RSPA and FRA have received numerous inquiries concerning the use of tank cars having higher test pressures than those authorized under these special provisions. RSPA is proposing to --Twenty-nine entries would be revised revise these provisions to clarify that by removing Special Provision B12 any class tank car with a higher test assigned to those entries in Column pressure than authorized also may be (7).

RSPA is proposing that these tank cars remain marked at the higher pressure specification while maintaining the currently applied safety relief device (e.g., DOT 105S300W, Safety Valve 150 LB). RSPA is proposing to remove a requirement in Special Provision 857 that the shipping name CHLOROPRENE must be marked on a tank car. This marking requirement is included in the proposed revision of 172.330(a)(1), RSPA also is revising the first sentence of Special Provision B78 to specify test pressure and clarify which rail cars are authorized. - Section 172.203. Currently, rail carrier shipping paper requirements are contained in both Parts 172 and 174. In this notice, RSPA proposes to move the shipping paper requirements in Part 174 to Pari 172. RSPA and-FRA believe that by consolidating the shipping paper requirements, including additional shipping paper entries for tank cars containing the residue of a hazardous material, compliance will be improved. Paragraph (e)(2) currently references paragraph (e)(3) and $ 174.25 for shipping paper description requirements for residues of hazardous materials in tank cars. These references would be replaced With a specific requirement to precede the basic shipping description with the wording "RESIDUE. LAST CONTAINED." ' Paragraph (g)(1) also would be revised to reflect the incorporation of shipping paper requirements currently contained in Part 174 by a requirement to identify a tail car, freight container, transport vehicle, or portable tank that contains a hazardous material by "reporting mark and number." Section 172.205. Based on a petition IP-1053] from AAR, RSPA would revise paragraph (f) for consistency with Environmental Protection Agency (EPA) hazardous waste manifest requirements for transportation by rail contained in 40 CFR 263.20(f). Section 172:330. Paragraph (a)(1) would be revised to clarify marking requirements for tank cars. Marking requirements currently contained in 172.102 special provisions and in Parts 173 and 179 would be incorporated into 172.330 or removed as part of this revision. The requirement to mark the proper shipping name or common name of a hazardous material on a tank car would be limited to Division 2.1 and 2.3 materials. Division 2.2 materials in a Class DOT 107 tank car, anhydrous ammonia, ammonia solutions with more than 50% ammonia, bromine and bromine solutions, hydrogen cyanide, . - chloroprene, and refrigerant or dispersant gases, as defined in 173.115. Section 172.510. Paragraph (a) would be revised to require the placement of each placard on a white square background for each class DOT 113 tank car used to transport a Division 2.1 (flammable gas) material. The white square background notifies railroad switching crews that the car may not be cut off while in motion. The current regulations only require rail cars containing Divisions 1.1 and 1.2 explosives. Division 2.3 Hazard Zone A materials and Division 6.1 PG1 Hazard Zone A materials to have the white square background, but not the class DOT 113 tank car/This change will simplify the switching requirements for rail cars by communicating, through a white square background, that a class DOT 113 tank car transporting a Division 2.1 material may not be cut off while in motion. RSPA and FRA believe that this requirement will make it easier to train yard switching employees and reduce the potential for overspeed impacts. The inner support system for class 113 tank cars is designed to withstand loads producing accelerations of 7"g" longitudinal, 3"g" transverse, and 3"g" vertical. Consequently, it is imperative that railroads shove this . class of car to rest to prevent yielding . of the support-system.o.s i: Sections 172.510 and 172.526. Provisions applying to the specifications and use of RESIDUE placards would be removed in these sections. Hie RESIDUE placard is not required by any other mode and, because the information provided through a RESIDUE placard can be adequately conveyed through primary and subsidiary placards and shipping paper information, RSPA and FRA believe that this placard is unnecessary. Further, FRA reports that during the last six years its inspectors cited missing, faded, or incorrect placards on nearly 22.000 occasions. By removing the RESIDUE placard requirement; RSPA and FRA believe that offerors will use permanent adhesive placards, such as those used on highway vehicles, thereby increasing compliance with HMR placarding requirements. Also, RSPA and FRA understand that Transport Canada is considering removing the RESIDUE placard from its Transportation of Dangerous Goods Regulations to the extent that, in December 1903, it issued a newsletter asking for public comment. Such an action by Transport Canada would have a direct effect on transborder shipments; consequently, RSPA and FRA believe a proposal to remove this requirement from the HMR is appropriate. Part 173 Section 173.24b. RSPA is proposing to amend paragraph (a) to recognize the insulation properties of thermal protection applied to tank cars. The proposed rule would allow for a "mid range" temperature for the calculation of outage and filling limits, provided the insulation qualities provide an overall thermal conductance at 15.5C (60F) of no more than 10.22 kilojoules per hour'per square meter per degrees Celsius (0.5 Btu per hour per square foot per degree F) temperature differential. This proposal is based on a petition for rulemaking submitted by the Propane - Gas Association of Canada [P-1251], developed in cooperation with Transport Canada. Section 173.29. Paragraph (f) would be removed, consistent with the proposed removal of 172.510(c). Section 173.314. Paragraph (b)(5), which contains provisions for marking the proper shipping name of certain Class 2 materials on tank cars, would be removed because these provisions also appear in 172.330. Paragraph (b)(6) would be redesignated (b)(5) and amended to revise requirements for heat-resistant gaskets. In 1988, the National Transportation Safety Board . (NTSB) recommended that FRA: (1) : establish performance standards for determining the acceptability of heatresistant gaskets on tank cars; and (2) evaluate the effect on gasket : compatibility and heat-resistant performance of sealants used for installing gaskets on tank cars. NTSB recommended that FRA establish performance criteria to decide what sealant is acceptable and conditions for its use. (Butadiene Release and Fire from GATX 55996 at the CSX Terminal Junction Interchange, New Orleans, Louisiana, September 8,1987 (NTSB/ HZM-88/01)). As a result of the NTSB recommendation, RSPA published an Advanced Notice of Proposed Rulemaking (ANPRM) on May 18,1990, under Docket HM-175A [Notice 90-8; 55 FR 20242] requesting comments on gasket specifications and the use of sealant materials. Commenters to the ANPRM expressed concerns regarding the technical complications for defining gasket specifications in the regulations, since there are many variables in torquing values for the fitting closure/' gasket combination and the chemical compatibility of the gasket material. In a Notice of Proposed Rulemaking (NPRM) published October 8,1993 (58 FR 52574] under Docket HM-175A, RSPA and FRA announced that several CMA 111191 65494 Federal Register / Vol. 60, No. 243 / Tuesday, December 19, 1995 / Proposed Rules topics, including gasket specifications, certain commodities, would be raised in earlier notices either were too removed.

Although the commenters to the Part 174 ANPRM pointed out many technical complications associated with defining gasket specifications for all products In 1985, AAR petitioned RSPA (P983) to rewrite Part 174, stating that the regulations in this part are "awkwardly authorized in tank cars, RSPA and FRA arranged, often redundant, and in many believe that a performance standard for places obsolete." AAR supplied a heat-resistant gaskets is necessary for ^ complete rewrite of Part 174 as part of Division 2.1 materials and anhydrous its petition.

The handbook shows that asbestos, a common heat-resistant gasket material, has a maximum temperature range of 230-340C (450- car testing), HM^181 (mandated* performance packaging standards). HM166 (implemented many detailed changes to the HMR), HM-197 (adopted new requirements for TOFC/COFC shipments), and HM-212 (considering new standards for tank car unloading and attendance) have addressed - 650'F). Consequently, RSPA is numerous suggestions contained in proposing tospecify that a heat-resistant petition P-983. This notice proposes gasket can survive temperatures at or- additional changes based on P-983, above 230C. This is comparable to the including simplification of standards for temperature indicated in the Fluid Sealing Association's handbook. This proposal also would expand the use of heat-resistant gaskets to all Division 2.3 materials. - -s Commenters stated that to seal a joint, the installed gasket is compressed (by inspection of tank cars by railroads and revisions in documentation requirements of Part 174.

The use of sealants for installing gaskets is therefore unnecessary and may lead to gasket displacement. Based on these comments, RSPA is proposing to prohibit the use of sealants for installing gaskets on tank cars used to transport Division 2.1 and 2.3 materials and anhydrous ammonia. RSPA also is proposing to authorize The section would be revised to reflect. language contained in Parts 175 and 177 for unacceptable hazardous materials shipments. Section 174.8 through 174.10. Inspection requirements currently contained in 174.8,174.9 and 174.10 would be consolidated into 174.9 to clarify a railroad's inspection duties at points of origination, interchange points and other locations where rail cars must Class DOT 112) and 112T specification be inspected. Sections 174.8 and 174.10 tank cars for the transportation of would be removed. Section 174.9 would dimethyl ether.

This proposal is based on an conditions that may make the car unsafe exemption issued to Aeropres for transportation. Corporation (DOT-E 11000) and a . Under FRA's Railroad Freight Car petition for rulemaking (P-1253). RSPA Safety Standards (FCSS (49 CFR Part also is proposing to remove Note 2 in 215]), each railroad must inspect a paragraph (c) of the table. For the entry freight car at each location where it is "Ammonia, anhydrous or ammonia placed in a train. The inspection must solutions >50 percent ammonia" in the be made by: (1) a "designated inspector" second column "Note 2" would be under 215.11; or (2) a train crew revised to read "Note 3''-This would member where a designated employee is allow shippers to calculate the outage not on duty (see Appendix D to Part and filling limits for tank cars based on 215). As a rule, train crew members changes proposed in 173.24b. inspect for "imminent hazardous In addition, paragraph (i), which conditions" that are likely to cause an .. provides alternate settings for safety accident or casualty before the train relief valves on tank car tanks used for arrives at its destination. Examples provided in Appendix D include: car body leaning or listing to one side, objects dragging below, broken or missing safety appliance, lading leaking from a placarded hazardous materials car, and broken or extensively cracked wheel. In addition to the requirements above, the HMR require an inspection of each placarded railcar when received in "interchange." This notice proposes to remove the requirement to inspect placarded railcars at interchange, simply because railroad operations now permit the interchange of railroad equipment in outlying locations, usually on mainline track, that may not be acceptable for the performance of a proper inspection. For example, in -"run-through" train operations, the train crew of the receiving railroad simply assumes responsibility of the train from the delivering train crew. No locomotives or railcars are added or removed. Since the train may exceed one mile in length, portions of the train, including portions that may have a placarded railcar containing a hazardous material, may not be accessible to the receiving train crew because of bridges, tunnels, or terrain. As proposed, RSPA would make the locations of inspection consistent with those in the FCSS, issued by the FRA. RSPA does not intend to change the . railroad's current inspection practices nor require the railroad to inspect railcars containing a hazardous material on a more frequent basis than the required presently in the HMR and FCSS. The proposed rule simply makes clear that a railroad must inspect a hazardous material laden car at locations that now require an inspection under the FCSS (by the train crew or a designated employee, where such employees are on duty). The proposed rule further clarifies that a railroad employee need not climb each railcar to determine if, in fact, the railcar conforms to the HMR These inspections may be performed at "ground level." Where the rule proposes to require a ground level inspection for "securement of closures," RSPA and FRA believe railroad employees can determine, from the ground, whether or not protective housings are open, whether or not manway openings (on non- or low-pressure tank cars) are in the "up" position, and whether or not the manway bonnet cover (on pressure tank cars) is open. At the bottom of the car, FRA and RSPA believe that railroad employees can determine whether or not the bottom outlet cap is in the proper, applied position. Section 174.11. SectionT74.11 would be removed because it merely references CMA 111192 Federal Register / Vol. 60, No. 243 / Tuesday, December 19. 1995 / Proposed Rules 65495 5 171.12a for transportation of Canadian shipments or packagings by rail car within the U.S. Section 174.18. Section 174.18 concerning the handling of astray packages of hazardous materials is obsolete; therefore this section would be removed. Section 174.24. Shipping paper requirements for rail carriers in Part 174 would be moved to Part 172. Revised 174.24 would cross-reference shipping paper requirements in Part 172. Section 174.25. When an accident occurs on the railroad, it is customary to identify the transport vehicle or freight container involved by the use of reporting marks. These marks are used for routing, cost accounting, and for tracing (or locating) individual - shipments in the transportation system. If an emergency responder were to ask about the contents of an individual shipment by reporting mark, a rail carrier could provide immediate emergency response information, a copy of the shipping paper, routing information, and the name, telephone number, and location of the shipper. This information is much more detailed than simply conveying to the emergency responder the type of placard applied to the packaging. Consequently, RSPA proposes to remove the "placard notation'' requirement since it is outdated for emergency response communication. Removing the placard notation requirement would not, however, prohibit individual rail carriers from adopting comparable requirements, if they so choose. RSPA also is proposing to remove the requirement for a "placard endorsement" placed on a waybill near the reporting mark of each rail car, freight container, transport vehicle, or portable tank that contains a hazardous material when transported by rail. The current rule requires a unique endorsement based on the hazard class of the material shipped. Exceptions to the placard endorsement are provided for materials that do not require placarding (e.g., less than 1,001 pounds of a material listed in 172.504 Table 2, in most types of transport vehicles or freight containers), Class 9 materials, and combustible liquids). RSPA is - proposing to remove this requirement because technological advances in the railroad industry have made the use of the placard endorsement no longer necessary to communicate the presence of hazardous materials to railroad workers. As a general rule, railroads now use electronic data interchange and computer generated train consists (or manifests) to communicate the presence of these materials. Responders and railroad workers rely on the hazardous emergency valve repair or capping kit materials description and emergency under approved conditions. response information on train consists Section 174.55. This section would be and printed waybills rather than the revised for clarity. Based on a petition placard endorsement. As stated earlier, [P-1042] submitted by AAR, suggesting removing the endorsement would not that certain provisions of the existing prohibit individual rail carriers from section are meaningless or confusing, adopting comparable requirements at RSPA is proposing to streamline this their discretion. section.

Paragraph (a) would 'petition (P-942] indicating that these be removed because if a carrier complies pipes need to be left open only 5% of with paragraph (b), the carrier also is complying with paragraph (a), except for the "consecutively numbered ... , j notice." Based on current railroad technology and computer-based information systems, this notice is obsolete. Paragraphs (b) and (c) would be renumbered paragraphs (a) and (b), respectively. Newly designated paragraph (b) would be revised to reference shipping paper requirements of Part 172 and specify use of other forms of car movement documents. the time, 'when steam is applied. Section 174.69. This section would be removed, based on a petition from AAR '[P-1139J,'because it conflicts with applicable requirements in 172.514. Section 174.85. Based on corresponding changes in 172.510 and 172.526 to remove provisions for a RESIDUE placard, paragraph (c) would be revised to reference a rail car " containing a residue of a hazardous material rather than a rail car placarded "RESIDUE". Section 174.45. This section would be Part 179 removed because it merely references 171.15 and 171.16 and is redundant. Sections 174.47 and 174.4$.

No, 243 / Tuesday December 19. 1995 / Proposed Rules 1tj this nnnce, a pressure relief valve means a pressure relief device that is designed to open rapidly, or by opening in proportion to the increase in pressure over the opening pressure, and designed to reclose and prevent further flow of vapor after normal conditions have been restored. A nonreclosing pressure relief device is a pressure relief device actuated bv inlet static pressure and designed to function by rupturing (bursting) a pressure containing disc (rupture disc) and remains open after operation. Two ANPRMs published under Docket HM-175A (May 15, 1990; 55 FR 20242, and August 29,1990; 55 FR 35327) solicited comments on potential costs and safety benefits derived from improvements to the crashworthiness of tank cars and restrictions on continued use of tank cars in hazardous materials service that no longer meet current safety requirements. RSPA issued the ANPRM, in part, to address an AAR petition requesting an increase in the start-to-discharge pressure of a nonreclosing pressure relief device and a reduction in the size of the upstream nozzle (P-1083). Commenters responding to the ANPRM suggested that tanks with a 60 psig test pressure and built with 7/16 inch wall thicknesses could be converted to a 100 psig tank test pressure (subject to an inspection and AAR approval), but opposed any conversion of DOT 115A or AAR 206W tank cars because of wall thickness. Most commenters supported increasing the start-to-distharge pressure of a nonreclosing pressure relief device to prevent rupture of the disc from in-transit pressure surges. The Railway Progress Institute (RPI) suggested in its comment that the optimum flow capacity for a pressure relief device is the minimum required to prevent tank car rupture in fire conditions. The RPI and other commenters opposed increasing the flow capacity of certain pressure relief valves and stated that both large and small capacity pressure relief valves discharge the same amount of product. Large capacity pressure relief valves, as opposed to small capacity valves, release large amounts of product for brief durations. A petition for rulemaking submitted by the Chemical Manufacturers " Association (CMA) supported the ANPRM and AAR's petition (P-1270). CMA suggested that reclosing pressure relief valves should have a start-to- discharge pressure setting consistent with several DOT exemptions for nonreclosing pressure relief devices (i.e., 165 percent of the tank test pressure or 33 percenl of the tank burst pressure). RSPA published an NPRM under Docket HM-175A on October 8,1993 (58 FR 52574) but did not propose changes to the HMR concerning pressure relief devices. Based on the merit of comments to Docket HM-175A and a petition for rulemaking [P-10831, RSPA is proposing to consolidate the pressure relief device requirements now contained in 173.314(i), 179.100-15, 179.200-18, 179.201-7, and 179.220-19 into a new 179.15. This proposal incorporates a performance-based flow capacity requirement to prevent excess pressure build-up within the tank, under fire conditions for both reclosing , and nonreclosing pressure relief devices. Further, RSPA is not proposing an increase in the flow capacity of a pressure relief device (including those devices used on tank cars transporting materials toxic by inhalation), based on comments received to Docket HM175A.' For most tank car specifications, the current start-to-discharge pressure setting for pressure relief devices is 30 percent of the tank burst pressure (33 percent of the tank burst pressure for certain commodities listed in 173.314(i) and in two DOT exemptions: DOT-E 10288 and DOT-E. 10328). Flow capacity of the pressure relief device is set at 33 percent of the tank burst pressure. For nonpressure tank car specifications, however, the start-to-discharge pressure setting of a pressure relief device is about 15 percent of the tank burst pressure. To allow for an equivalent start-todischarge pressure setting for both pressure and nonpressure tank car specifications, RSPA is proposing a start-to-discharge pressure setting of up to 33 percent of the tank burst pressure for all commodities and specifications. Based on the physical-chemical properties of the material (vapor pressure, static head, and gas padding pressure of the product within the tank), this notice also proposes to authorize a reduction in the.start-to-discharge pressure setting. This proposal is consistent with Section VIII, UG-125, of the American Society of Mechanical Engineers Pressure Vessels Code (ASME) and an exemption (DOT-E 11184) that authorizes the transportation of certain flammable liquid products in DOT 105J300W tank cars having a start-to-discharge pressure setting of 75 psig as opposed to 225 psig. Further, because of costs associated with modifying existing tank cars to conform to this proposed requirement and because there is no apparent safety reason to require any modification to existing tank cars, this NPRM proposes to allow the continued use of tank cars having a start-to- discharge pressure set at 15 percent of buret. In addition, this notice proposes that a tank car equipped with a nonreclosing pressure relief device must have installed a rupture disc designed to buret at 33 percent of the tank burst pressure within one year after any final rule issued in this docket. For example, a DOT 111A100W2 tank car would have a rupture disc designed to burst at 165 psig within one year after any final rule issued in this-docket. This proposal is based on provisions in several exemptions (e.g,, DOT-E 10118 and DOT-E 10354), several petitions for rulemaking, and the number of rupture disc failures reported to RSPA's Hazardous Materials Information System. - The location for pressure relief devices would be revised in proposed paragraph (g) to allow for the mounting of pressure relief valves on a hinged manway cover plate. The current regulations require mounting a pressure relief valye on the tank dome, manway cover plate, or on a nozzle on top of the tank shell. This notice proposes to require a pressure relief device to communicate with the vapor space above the lading/ Sections 179.100-15,179.200-18, 179.201-7, and 179320-19. These sections contain provisions for safety relief devices. For consistency with the proposed consolidation of safety relief device provisions in 179.15, RSPA is proposing to remove these sections from the HMR. Sections 179.101-1 and 179.201-1. RSPA proposes to revise individual specification requirements for pressure tank cars and non-pressure tank cars, respectively. The proposed revisions will correct many typographical errors and remove several special references that are no longer applicable. RSPA also proposes to add a new class "DOT 120A" specification tank car and a new "DOT H1A60W6" specification tank car in the table based on two petitions for rulemaking [P-1044 and P-1119] from AAR. Furthermore, RSPA proposes to remove certain entries from the table since these provisions are currently found in the text proceeding the table (see for example 5179.200-11, 179.200-14, and 179.200-16). Section 179.102-4. Paragraph (d), which specifies at least one safety relief valve on a tank car tank used to transport vinyl fluoride, inhibited, would be removed, consistent with the proposed consolidation of safety relief device provisions in 179.15.

(3) The vapor tight pressure of a reclosing pressure relief valve must be at least 80 percent of the start-to- discharge pressure. (4) The valve flow rating pressure must be 110 percent of the start-to- discharge pressure for tanks having a minimum tank burst pressure greater than 34.47 Bar (500 psig) and from 110 percent to 130 percent for tanks having a minimum tank burst pressure less ' than or equal to 34.47 Bar (500 psig). (5) The tolerance for a reclosing pressure relief valve is 3 psi for valves with a start-to-discharge pressure of 6.89 Bar (100 psig) or less and 3 percent for valves with a start-to-discharge pressure greater than 6.89 Bar (100 psig). (c) Flow capacity ofpressure relief systems. The total flow capacity of each reclosing and nonxeclosing pressure relief device must conform to Appendix A of the Association of American ' Railroads Specifications for Tank Cars. (d) Flow capacity tests. The - manufacturer of any reclosing or nonreclosing pressure relief device must design and test the device in accordance with Appendix A of the Association of American Railroads Specifications for Tank Cars. (e) Combination pressure relief . systems. (1) When a reclosing pressure relief valve is used in combination with a breaking pin device,.the breaking pin must be designed to fail at the start-to- discharge pressure specified in paragraph (b) of this section, and the reclosiiig pressure relief valve must be designed to discharge at 95 percent of the start-to-discharge pressure. (2) When a reclosing pressure relief valve is used in combination with a rupture disc, the rupture disc must be designed to fail at the start-to-discharge pressure specified in paragraph (b) of this section, and the.reclosing pressure relief valve must be designed to discharge 95 percent of the start-to- discharge pressure.
