Privacy Act This final rule is the culmination of two rulemaking proceedings initiated by the Research and Special Programs Administration (RSPA), the predecessor agency to the Pipeline and Hazardous Materials Safety Administration (PHMSA), in order to reduce the risks of battery-related fires in transportation and in response to incident reports and recommendations of the Federal Aviation Administration (FAA) and National Transportation Safety Board (NTSB). The final rule continues in force a limited ban on the transportation of certain lithium batteries as cargo aboard passenger aircraft. It tightens other standards for the testing, handling, and packaging of lithium batteries, in each case to reduce the likelihood or consequence of a lithium battery-related fire in transportation. Although we developed these standards in separate rulemaking proceedings, we have combined them for publication in this single final rule in the interests of clarity and consistency and to minimize regulatory burdens. I. Background The final rule adopted today is one of several actions PHMSA is taking, in consultation with the FAA, to improve the safety of lithium batteries in transportation. Beyond rulemaking and enforcement, PHMSA and FAA are promoting and advancing non-regulatory solutions through a broad group of public and private sector stakeholders that share our interest in battery and transportation safety. We are working with representatives of the NTSB, the Consumer Product Safety Commission, manufacturers of lithium batteries and battery-powered products, airlines, airline employee organizations, testing laboratories, and the emergency response and law enforcement communities to share and disseminate information about battery-related risks and developments and to promote improvements in industry standards and best practices. We report on these non-regulatory activities through our public Web site at http://safetravel.dot.gov . A. Overview of Lithium Battery Risks Lithium batteries are considered a hazardous material for purposes of transportation regulation because they can overheat and ignite in certain conditions and, once ignited, can be especially difficult to extinguish. In general, the risks posed by lithium batteries are a function of battery size (the amount of lithium content and corresponding energy density) and the likelihood of short-circuiting or rupture. By comparison to standard alkaline batteries, most lithium-ion batteries manufactured today contain a flammable electrolyte and have a very high energy density. A lithium battery is susceptible to thermal runaway, a chain reaction leading to self-heating and release of its stored energy. The increasing manifestation of these risks, inside and outside of transportation, drives the need for stricter safety standards. Once used primarily in industrial and military applications, lithium batteries are now found in a variety of popular consumer items, including cameras, laptop computers, and mobile telephones. The numbers, types, and sizes of lithium batteries moving in transportation have grown steadily in recent years with the increasing popularity of these and other portable devices and the corresponding proliferation of battery designs, manufacturers, and applications. Like other products that contain hazardous materials, lithium batteries can be transported safely, provided appropriate precautions are taken in design, packaging, handling, and emergency response. The rule adopted in this proceeding strengthens the current regulatory framework by imposing stricter and more effective safeguards, including design testing, packaging, and hazard communication measures, for certain types and sizes of lithium batteries in certain transportation contexts. These adjustments are risk-based and data-driven, reflecting incident reports, laboratory testing, and other information that together promote better understanding of risks and [[Page 44931]] consequences in relationship to specific risk variables: Battery technology. In the rulemaking proposals that gave rise to the final rule, we differentiated between ``primary'' (or non- rechargeable) and ``secondary'' (or rechargeable) lithium batteries. This distinction, which is well established in international standards, is related to the battery composition. ``Primary'' (non-rechargeable) lithium batteries generally contain lithium metal, while most ``secondary'' (rechargeable) lithium batteries contain an ionic form of lithium (lithium-ion). The technology used in lithium batteries has a significant impact on the battery application and, all other factors being equal, on corresponding transportation risks. For purposes of this rulemaking, we use the term ``primary lithium battery'' to refer to a non-rechargeable battery and the term ``secondary lithium battery'' to refer to a rechargeable battery. In most cases, this distinction will differentiate between different battery technologies. Although we understand that the distinction is being called into question by technological and market developments, we believe the regulatory definitions continue to have merit at this time, recognizing that further regulatory refinement will be necessary to respond to further technological developments and our growing understanding of transportation risks. Transportation mode. The consequence of a lithium battery-related fire depends largely on the transportation context. In weighing the costs and benefits of regulation, we consider the mode of transportation and impose the strictest standards in air transportation, particularly passenger service. Although most battery- related fires have caused only property damage or delays in ground transportation, even a small fire aboard an in-flight aircraft threatens catastrophic consequences. Battery size. The degree of risk posed by lithium batteries is largely a function of the amount of stored energy, which is in turn a function of the number and relative lithium content of battery cells. These size standards are the accepted categorization of lithium batteries under the United Nations Recommendations and international regulatory bodies such as the International Civil Aviation Organization (ICAO). A cell is a single electro-chemical unit; a battery consists of one or more connected cells. The size of a cell or battery is determined by its lithium content, as summarized in the following chart: Table 1.--Battery and Cell Category Definitions ---------------------------------------------------------------------------------------------------------------- Small (no more than) Medium (between) Large (more than) ---------------------------------------------------------------------------------------------------------------- Cells: Primary...................... 1 g Li. 1 g and 5 g Li. 5 g Li. Secondary.................... 1.5 g ELC.* 1.5 g and 5 g ELC. 5 g ELC. Batteries: Primary...................... 2 g Li. 2 g and 25 g Li. 25 g Li. Secondary.................... 8 g ELC. 8 g and 25 g ELC. 25 g ELC. ---------------------------------------------------------------------------------------------------------------- * ELC (Equivalent Lithium Content). Quantity. The number of lithium batteries in a shipment can also affect the severity of an incident. For example, several thousand small lithium batteries consolidated together present a higher potential risk than a shipment of a single lithium battery, because one burning primary lithium or secondary lithium battery can produce enough heat and energy to propagate to other lithium batteries in the same overpack, freight container, or cargo hold. Product Design, Package Integrity, and Transportation Handling. The risks that a lithium battery will short-circuit or rupture are a function of design, packaging, and handling. As with many hazardous materials, the risk of a transportation incident involving lithium batteries can be reduced by strengthening packaging and reducing the likelihood and impact of rough handling. The amendments adopted here include tightened testing standards to ensure that batteries that pose the greatest risk in transportation are designed to withstand normal conditions of transportation and packaged to minimize risks of mishandling or damage in transit. Emergency Response. In developing the final rule, we paid special attention to the potential consequences of lithium battery-related fires. Although we take fire hazards seriously in all modes, we must be particularly concerned about the possibility of an uncontrolled fire aboard an aircraft. To evaluate the hazards posed by primary lithium batteries in air transportation, FAA's Technical Center initiated a series of tests to assess their flammability characteristics. FAA published a technical report detailing the results of the tests in June 2004 (DOT/FAAIARI-04/ 26). The battery tests were designed to test the batteries in an environment that is similar to actual conditions possible in a suppressed cargo fire. The FAA tests showed that the packaging materials delayed the ignition of the batteries, but eventually added to the fire loading and contributed to the battery ignition, even after the original (alcohol) fire had been exhausted. In addition, the packaging material held the batteries together, allowing the plastic outer coating to fuse the batteries together. This enhanced the probability of a burning battery igniting adjacent batteries, increasing the propagation rate. The technical report, which can be found in the docket for this rulemaking, concluded that the presence of a shipment of primary lithium batteries can significantly increase the severity of an in-flight cargo compartment fire. In addition, the report concluded that primary lithium batteries pose a unique threat in the cargo compartment of an aircraft because primary lithium battery fires cannot be suppressed by means of Halon, the only FAA-certified fire suppression system permitted for use in cargo compartments of a passenger-carrying aircraft operating in the United States. FAA also conducted a series of test to determine the flammability of secondary lithium batteries and cells and issued a final report detailing the results in September 2006 (DOT/FAA/AR-06/38). This report can be found in the docket for this rulemaking. Flames produced by the batteries are hot enough to cause adjacent cells to vent and ignite. The report also concluded that Halon is effective in suppressing the electrolyte fire and preventing any additional fire from subsequent cell venting. The lithium-ion cells will continue to vent due to high temperatures but will not ignite in the presence of Halon. [[Page 44932]] B. LAX Incident and NTSB Recommendations The notices of proposed rulemaking (NPRMs) in these proceedings both tied the need for tighter safety standards to an April 28, 1999 fire at Los Angeles International Airport (LAX). The LAX incident involved a shipment of two pallets of primary lithium batteries that caught fire and burned after being off-loaded from a Northwest Airlines flight originating in Osaka, Japan. The two pallets involved in the fire contained 120,000 small primary lithium batteries that were excepted from domestic and international regulatory requirements applicable to hazard communication (i.e., marking, labeling, and shipping papers) and packaging. The packages on the pallets were damaged during handling at LAX, and this damage is believed to have initiated the subsequent fire. Northwest ground employees initially fought the fire with portable fire extinguishers and a fire hose. Each time the fire appeared to be extinguished, it flared up again. The LAX incident illustrated the unique transportation safety problems posed by lithium batteries, including the risk of rough handling in transit, resulting short-circuiting, thermal runaway, ignition of adjacent batteries, and the ineffectiveness of halon as an extinguishing agent. The NTSB conducted a full investigation of the LAX incident. The NTSB's final report, issued November 16, 1999, included five safety recommendations addressed to RSPA: A-99-80: Together with the Federal Aviation Administration, evaluate the fire hazards posed by lithium batteries in an air transportation environment and require that appropriate safety measures be taken to protect aircraft and occupants. The evaluation should consider the testing requirements for lithium batteries in the United Nation's Transport of Dangerous Goods Manual of Tests and Criteria, the involvement of packages containing large quantities of tightly packed batteries in a cargo compartment fire, and the possible exposure of batteries to rough handling in an air transportation environment, including being or abraded open. A-99-81: Pending completion of your evaluation of the fire hazards posed by lithium batteries in an air transportation environment, prohibit the transportation of lithium batteries on passenger-carrying aircraft. A-99-82: Require that packages containing lithium batteries be identified as hazardous materials, including appropriate marking and labeling of the packages and proper identification in shipping documents, when transported on aircraft. A-99-83: Pending completion of your evaluation of the fire hazards posed by lithium batteries in an air transportation environment, notify the International Civil Aviation Organization's Dangerous Goods Panel (ICAO DGP) about the circumstances of the fire in the Northwest Airlines cargo facility at Los Angeles International Airport on April 28, 1999. Also pending completion of your evaluation of the fire hazards posed by lithium batteries in an air transportation environment, initiate action through the Dangerous Goods Panel to revise the Technical Instructions for the Safe Transportation of Dangerous Goods by Air to prohibit the transportation of lithium batteries on passenger-carrying aircraft. A-99-84: Initiate action through the Dangerous Goods Panel to revise the Technical Instructions for the Safe Transportation of Dangerous Goods by Air to require that packages containing lithium batteries be identified as hazardous materials when transported on aircraft. C. Additional Incidents The April 1999 LAX incident was not an isolated event; numerous incidents involving lithium batteries have been reported in the intervening years, most in the period since we initiated these rulemaking proceedings. Fortunately, none of the aviation-related incidents has resulted in death or serious injury; most of the incidents occurred either before or after flight. Some of these additional incidents are described below: On November 3, 2000, in Portland, Oregon, a small primary lithium battery short-circuited, causing a small fire and rupture of the battery. The primary lithium battery burned through its inner packaging and charred an adjacent package. The short-circuited battery had long flexible protruding positive and negative terminals. On April 12, 2002, small primary lithium batteries packaged in a fiberboard box ignited during handling in Indianapolis, Indiana. On August 9, 2002, a small secondary lithium battery in an electronic handheld device short-circuited, causing surrounding packing materials (bubble wrap) to catch fire. On August 7, 2004, large prototype secondary lithium batteries shipped under a competent authority approval from California to Europe apparently started a fire in a unit load device (ULD) during loading for a transatlantic flight (Memphis-Paris). The ULD and many other packages in it were damaged or destroyed by fire. On February 11, 2005, an undeclared package containing 18 small primary lithium batteries caught fire during unloading in White Bear Lake, Minnesota. Cargo handlers reported hearing a ``pop'' sound and then seeing the box ``lifted'' off the conveyor belt by the force. The package had been flown from Los Angeles to Minneapolis and was to be trucked to Clear Lake, Wisconsin. On or about June 29, 2005, the contents of a ULD caught fire onboard a flight from Shanghai, China to the United States. Airline ground personnel discovered evidence of the fire after the plane landed safely in Ontario, California. A package containing a secondary lithium battery pack was identified as the source of the fire. On March 3, 2006, a U.S.-bound package containing secondary lithium batteries ignited in an outbound air transport station in Shenzhen, China. On July 17, 2006, a package with no marking or labeling containing 122 secondary lithium batteries of various sizes caught fire while being held in bond for customs clearance in Korea, after transportation by air from Vienna, Austria. On February 10, 2007, shortly after takeoff of a commercial flight, a fire ignited in a passenger bag stowed in an overhead bin. Although the fire is still under investigation, preliminary reports indicate both small lithium ion and small primary batteries were involved in the incident. On March 1, 2007, a package sent by an eBay vendor via the United States Postal Service, containing 24 primary lithium batteries, caught fire at the Sydney Australia Mail Gateway Facility. The package had been transported to Sydney from Los Angeles on a passenger aircraft. D. Recalls In August and October of 2006 and March of 2007, several leading computer manufacturers recalled nearly 10 million notebook computer secondary lithium batteries based on manufacturing defects. The batteries in the 2006 recalls, manufactured by Sony Energy Devices Corporation, were voluntarily recalled in coordination with the U.S. Consumer Product Safety Commission (CPSC). According to CPSC reports, these defective secondary lithium batteries can spontaneously overheat and cause fires. The batteries in the March 2007 voluntary recall were manufactured by Sanyo Electric Company, Ltd. and designed to be extended-life batteries for Lenovo ThinkPad notebook computers. According to CPSC, the Sanyo lithium-ion batteries pose a fire hazard if the battery is struck forcefully on the corner (e.g., a direct fall to the ground). E. Regulatory Actions To Address Transportation Risks Posed by Lithium Batteries of All Types As we explained above, the regulatory actions we are taking today are part of [[Page 44933]] a broader and ongoing effort to address the transportation risks posed by lithium batteries. Even as the measures adopted in this final rule progressed through the rulemaking process, more data surfaced concerning lithium battery risks. These developments have lent further support to the proposed approaches and spurred additional proposals for regulatory and non-regulatory change. Inevitably, further technological advances, new product development, and market shifts will drive continued change in risks and benefits. We are committed to addressing those changes in a manner that safeguards our transportation systems and the traveling public, while promoting positive technological advances and minimizing regulatory costs and burdens for consumers and industry, including small businesses. To that end, we will continue to collect and analyze data concerning the risks posed by batteries and battery-powered devices of all types. We are committed to working with all affected stakeholders to identify risks and develop solutions, especially including non- regulatory solutions. In keeping with DOT regulatory policies and procedures, we will analyze the effectiveness of our rules over time, with a commitment to updating or eliminating any regulations that become unnecessary or unduly costly with changes in technology or transportation operations. Recognizing that the risk and benefit profile is and has been dynamic, the final rule adopted today is best understood against the backdrop of existing and ongoing regulatory actions, including the separate rulemaking proposals that gave rise to this consolidated proceeding. By way of background, we begin with a discussion of regulatory requirements in place at the time of the LAX incident and NTSB recommendations. 1. Regulatory Requirements Prior to Adoption of this Final Rule. Under the Hazardous Materials Regulations (HMR, 49 CFR Parts 171-180), most lithium batteries and cells of all types and equipment containing or packed with lithium batteries or cells of all types are regulated as a Class 9 (Miscellaneous) hazardous material. A Class 9 material is one that presents a hazard during transportation, but that does not meet the definition of any other hazard class. The HMR require lithium batteries to be tested in accordance with a series of tests in Section 38.3 of the UN Test Manual. The tests are designed to ensure that a battery design type is capable of withstanding conditions encountered in transportation. The tests include: (1) Test T.1 Altitude simulation, (2) Test T.2 Thermal test, (3) Test T.3 Vibration, (4) Test T.4 Shock, (5) Test T.5 External short circuit, (6) Test T.6 Impact, (7) Test T.7 Overcharge, and (8) Test T.8 Forced discharge. In addition, lithium batteries and cells must be: (1) Equipped with an effective means of preventing short circuits; (2) packaged in UN standard packagings meeting the Packing Group II performance level; and (3) identified on shipping papers and by package markings and hazard warning labels. See Sec. 173.185(e). Section 173.185 of the HMR contains exceptions from the packaging and hazard communication requirements of the HMR for small and medium- size lithium batteries and cells. Small and medium-size lithium batteries and cells must be packaged in strong outer packagings, and in a manner to protect against short circuits, but UN standard packagings are not required, and the requirements in Part 172 of the HMR applicable to shipping papers, marking, labeling, and emergency response information do not apply. Small lithium batteries and cells are also excepted from testing in accordance with the UN Test Manual. 2. Changes to International Regulations. Acting on a proposal by the United States, in December 2000, the United Nations Sub-Committee of Experts on the Transport of Dangerous Goods revised the UN Recommendations to: (1) Revise the lithium battery testing requirements in the UN Test Manual to provide more precise descriptions of the testing procedures and criteria and require more extensive testing to measure temperature, altitude, vibration, shock, impact, overcharge, forced discharge and intentional short; (2) eliminate an exception that permitted medium-size lithium batteries to be transported as unregulated material; (3) require testing of small lithium batteries to ensure they can withstand conditions encountered during transportation; (4) impose hazard communication and packaging requirements for small lithium batteries; and (5) provide exceptions for passengers and crew to carry lithium battery-powered equipment aboard an aircraft. These revisions were subsequently included in the 2003-2004 ICAO Technical Instructions. As a result of these revisions to the international regulations, NTSB classified recommendations A-99-83 and -84 as ``Closed-Acceptable Alternate Action.'' 3. HM-224C Rulemaking. On April 2, 2002, we issued an NPRM (HM- 224C; 67 FR 15510) proposing changes to current HMR requirements for the transport of lithium batteries consistent with the changes adopted in the UN Recommendations and ICAO Technical Instructions. These amendments were intended to improve the safety of lithium batteries in transportation and harmonize U.S. and international standards. Specifically, we proposed to: (1) Adopt the revised lithium battery test scheme in the UN Test Manual; (2) eliminate the exception for medium-size lithium batteries; (3) require testing of small lithium batteries; (4) impose hazard communication and packaging requirements for small lithium batteries; and (5) provide exceptions for passengers and crew to carry lithium battery-powered equipment aboard an aircraft. 4. HM-224E Rulemaking. Based in part on the June 2004 FAA technical report concerning the flammability characteristics of primary lithium batteries, discussed earlier in this preamble, on December 15, 2004, PHMSA published an interim final rule (IFR; Docket HM-224E; 69 FR 75208) prohibiting the shipment of primary lithium batteries as cargo on passenger-carrying aircraft. The IFR prohibits the offering for transportation and transportation in commerce of primary lithium batteries and cells, and equipment containing or packed with large primary lithium batteries (i.e., batteries containing greater than 25 grams of lithium) as cargo aboard passenger-carrying aircraft. In addition, equipment packed with or containing small or medium-size primary lithium batteries (i.e., batteries containing 25 grams or less of lithium) must be transported in accordance with Special Provisions A101 or A102. Under these Special Provisions, a primary lithium battery or cell packed with or contained in equipment may not exceed a net weight of 5 kg (11 pounds). Finally, the outside of each package that contains a primary lithium battery or cell forbidden for transport aboard passenger carrying aircraft must be marked ``PRIMARY LITHIUM BATTERIES--FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT.'' 5. Additional Recent Amendments to International Regulations. At the international level, interest in the safe transportation of lithium batteries continues to grow as the number of lithium battery incidents (including non-transportation-related fires and product recalls) increases. The following activities and discussions of the ICAO Dangerous Goods Panel and the UN Sub-Committee of Experts on the Transport of Dangerous Goods signal further safety enhancements to the [[Page 44934]] ICAO Technical Instructions and UN Recommendations: At its 2006 meeting (October 25--November 3, 2006), the ICAO Dangerous Goods Panel further considered amendments to the ICAO Technical Instructions concerning lithium battery safety. Based on a recommendation by the Panel, the ICAO Air Navigation Commission agreed to issue an addendum to the ICAO 2007-2008 Technical Instructions to prohibit the transport of lithium batteries that have the potential of producing a dangerous evolution of heat, fire, or short circuit as a result of being damaged or defective (e.g., those being returned to the manufacturer for safety reasons). In December 2006, the United Nations Committee of Experts on the Transport of Dangerous Goods, based in part on U.S. proposals, revised Special Provision 188 (SP 188) of the UN Recommendations to address the risk that lithium cells and batteries currently excepted from regulation may short circuit in transportation. These revisions (1) require individual packaging of lithium cells or batteries, (2) require protection against short circuits, accidental activation, and outer packaging of lithium battery-powered equipment; (3) eliminate the current exception from marking, documentation, drop testing, and gross weight limit for packages containing less than 24 lithium cells or 12 lithium batteries, and (4) standardize marking requirements for lithium batteries. Additionally, the UN Recommendations were amended to include separate dangerous goods list entries for metallic lithium and lithium ion batteries to assist shippers, transport personnel, and carriers in complying with the applicable regulations. PHMSA will carefully review any amendments to the international regulation and will consider further rulemaking action based on a robust notice and comment process. As previously stated, we are committed to working with all affected stakeholders to evaluate risks and develop potential solutions, especially non-regulatory solutions. II. Provisions of this Final Rule The continuing incidents and recalls and the results of the FAA testing discussed above reinforce the actions we are taking in this final rule and the need for ongoing analysis of the transportation risks presented by lithium batteries. As we explain in the following sections, the provisions of this final rule will provide additional protection against all lithium battery-related fires, regardless of their source, by enhancing hazard communication and emergency response and limiting transportation options based on the availability of effective fire suppression technology. This final rule addresses the proposals advanced in 2002 under Docket HM-224C and the provisions of the 2004 IFR published under Docket HM-224E. The following tables are provided for your convenience: ------------------------------------------------------------------------ ------------------------------------------------------------------------- As a result of HM-224E IFR the following requirements are already in effect: Primary lithium batteries are forbidden for transport aboard passenger aircraft. Primary lithium batteries transported by any means other than passenger aircraft must be marked ``PRIMARY LITHIUM BATTERIES-- FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT''. ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------- The following provision pertaining to lithium batteries is unchanged by this combined final rule: Requirements for large lithium batteries (> 25 grams). ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------- The following provisions have been modified as a result of this combined final rule: Section 175.10(a)(17) in that the equipment containing batteries and spares must be in carry-on luggage. ------------------------------------------------------------------------ ------------------------------------------------------------------------ ------------------------------------------------------------------------- The following new requirements will take effect as a result of this combined final rule: The exception for medium batteries is eliminated by aircraft and vessel. Small battery exception from UN testing is eliminated. A new marking paperwork requirement is added for medium batteries shipped as excepted via highway and rail transportation. A new marking paperwork requirement is added for small batteries that are shipped excepted. ------------------------------------------------------------------------ A. Docket HM-224C 1. Background: Proposed Requirements As mentioned above, our April 2, 2002, NPRM (67 FR 15510) proposed to: (1) Adopt the revised lithium battery test scheme in the UN Test Manual; (2) eliminate the current exceptions for medium-size lithium batteries of all types; (3) require testing of small lithium batteries of all types; (4) impose hazard communication and packaging requirements for small lithium batteries of all types; and (5) provide exceptions for passengers and crew to carry lithium battery-powered equipment aboard an aircraft. On June 15, 2005, we published an Initial Regulatory Flexibility Analysis (IRFA) (70 FR 34729) and requested comments on the potential small business impacts of the proposals in our April 2, 2002 NPRM. The issues raised by commenters to the IRFA are addressed in this document and the final regulatory flexibility analysis (FRFA), which can be found in the public docket for this rulemaking. 2.

Elimination of the Exception for Medium-size Lithium Cells and Batteries. In the NPRM, we proposed to eliminate the exception from most HMR requirements for medium-size lithium cells (including when packed or contained in equipment) containing 5 grams or less of lithium or lithium alloy and batteries (including when packed or contained in equipment) containing not more than 25 grams of lithium or lithium alloy per battery if they pass tests specified in Section 38.3 of the UN Test Manual. With the elimination of this exception, medium-size lithium batteries and cells of all types would have to be transported as Class 9 hazardous materials and conform to all associated hazard communication and packaging requirements. This exception has already been removed from the IMDG Code and the ICAO Technical Instructions, effectively requiring these lithium batteries to be transported as Class 9 materials when transported internationally by aircraft or vessel and in regulations applicable in other countries and regions throughout the world (e.g. European Road and Rail Agreements (ADR/RID). Several commenters urge PHMSA to retain this exception for domestic surface transportation. The Portable Rechargeable Battery Association (PRBA) states that retention of the exception for medium-size lithium batteries of all types will have the largest positive effect on reducing the cost impacts on small businesses and recommends PHMSA retain the exception for lithium-ion batteries containing no more than 16 grams of equivalent lithium content shipped at a state of charge of no more than 50%. PRBA states testing data clearly show that the degree to which a lithium-ion cell reacts to abuse is significantly affected by state of charge. PRBA also suggests we should consider retaining the exception for medium-size lithium batteries when the batteries are contained in or packed with equipment and shipped by ground only. PRBA states this exception would substantially reduce costs associated with shipping products as Class 9 materials and cover a significant number of products shipped by small businesses. In response to the proposal to eliminate the exception of medium sized batteries, Valence Technology, Inc. states PHMSA did not provide sufficient justification for eliminating the exception. SION Power asserts eliminating the exception for medium-size lithium batteries will adversely affect its commercial development and suggests that, in the case of primary lithium batteries, eliminating the exception will limit the size of batteries using smaller cells. SkyBitz favors scaling back the exception for medium-size lithium batteries by limiting the number of cells or batteries per package, rather than eliminating the exception. ACR Electronics, Inc. states PHMSA should retain the exception for medium-size lithium batteries provided they are contained in strong, waterproof safety equipment. We continue to believe that significant safety benefits can be achieved by requiring medium-size lithium batteries and cells of all types to be shipped with appropriate hazard communication information. As recent incidents demonstrate, the hazards associated with these shipments should be communicated to transport workers and emergency response personnel to ensure safe handling in transportation and appropriate incident response actions. We are not convinced that requiring medium-size batteries to be transported with appropriate hazard communication information will impede the development or marketi","truncated":true,"body_characters":148559}
