    ii. Follow directions—The agency may ask you to respond to specific questions or organize comments referencing a Code of FederalRegulations (CFR) part or section number.

    iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

    iv. Describe any assumptions and provide any technical information and/or data that you used.

    v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

    vi. Provide specific examples to illustrate your concerns, and suggest alternatives.

    vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

    viii. Make sure to submit your comments by the comment period deadline identified.

    II. Proposed Rule Changes A. Updating ASTM Test Methods to Their Most Recent Version

    Refiners, importers and oxygenate blenders producing gasoline and diesel motor vehicle fuel are required to test reformulated gasoline (RFG), conventional gasoline (CG) and diesel fuel for various fuel parameters including aromatics, benzene, distillation, olefins, Reid Vapor Pressure, oxygenate content and sulfur. American Society for Testing and Materials (ASTM) test method D2622 is currently the designated test method for measuring sulfur1, 2 in gasoline and diesel fuel at the 500 ppm sulfur standard. ASTM test methods D5453, D6920, D3120 and D7039 are currently alternative test methods for measuring sulfur3, 4, 5, 6 in gasoline. ASTM test methods D5453 and D6920 are also alternative test methods for measuring sulfur7 in diesel fuel at the 500 ppm sulfur standard. ASTM D1319 is currently the designated test method for measuring olefins8 in gasoline and aromatics9 in diesel fuel and is also allowed as an alternative test method for measuring aromatics10 in gasoline. ASTM test method D5599 is currently the designated test method for measuring oxygenates11 in gasoline. ASTM test method D4815 is currently an alternative test method for measuring oxygenates12 in gasoline. ASTM test method D5769 is currently the designated test method for measuring aromatics13 in gasoline. ASTM test method D3606 is currently the designated test method for measuring benzene14 in gasoline. ASTM test method D86 is currently the designated test method for measuring the distillation15 of gasoline. ASTM test method D5191 is currently the designated test method for measuring the Reid Vapor Pressure16 of gasoline.

    Table 1 lists the designated analytical test methods and alternative analytical test methods which are being proposed to be updated for parameters measured under RFG, CG, and diesel fuels program in today's action. The Agency has reviewed these updated ASTM test methods and we are in agreement with the revisions contained in them which will result in improvements in the utilization of these test methods for the regulated industry. We believe that the revisions in the test method changes in today's proposed action are not significant changes that would cause a user of an older version of the same method to incur significant costs. All of the revisions were deemed necessary by ASTM so that improvements in the test method's procedures would ensure better operation for the user of the test method. Thus, EPA is proposing today to update the regulations for the following ASTM test methods: (1) ASTM D2622-05, the designated test method for measuring sulfur in RFG, CG, and alternative test method for diesel fuel at the 500 ppm sulfur standard, (2) ASTM D3120-06 1, alternative test method for sulfur in gasoline, (3) ASTM D5453-08a, alternative test method for sulfur in gasoline and diesel fuel at the 500 ppm sulfur standard, (4) ASTM D6920-07, alternative test method for sulfur in gasoline and diesel fuel at the 500 ppm sulfur standard, (5) ASTM D7039-07, alternative test method for sulfur in gasoline, (6) ASTM D1319-03 1, designated test method for measuring olefins in gasoline and aromatics in diesel fuel, as well as the alternative test method for measuring aromatics in gasoline, (7) ASTM D4815-04, alternative test method for measuring oxygenate content in gasoline, (8) ASTM D5599-00 (2005), the designated test method for measuring oxygen content in gasoline, (9) ASTM D5769-04, the designated test method for measuring aromatics in gasoline, (10) ASTM D3606-07, the designated test method for measuring benzene in gasoline, (11) ASTM D86-07b, the designated test method for measuring distillation properties of gasoline, and (12) ASTM D5191-07, the designated test method for measuring the Reid Vapor Pressure of gasoline.

Reid Vapor Pressure (gasoline) ASTM D5191-07, entitled, “Standard Test Method for Vapor Pressure of Petroleum Products (Mini-Method)”. B. Alternative Test Method for Olefins in Gasoline

    Refiners, importers and oxygenate blenders producing gasoline are required to test RFG, and CG for various fuel parameters including olefins. The test method for determining olefin content is specified in the regulation.

    Recently, the American Petroleum Institute (API) requested in a letter to EPA that ASTM D 6550-05 be designated by EPA as an alternative test method in the regulations for olefins15 in gasoline. EPA has evaluated API's request on this test method issue and agrees. Thus, EPA is proposing to allow ASTM D6550-05 as an alternative test method in the regulations for olefins in gasoline, provided that its results are correlated to ASTM D1319. The allowance of this additional alternative test method for olefins in gasoline will provide the regulated community additional flexibility in meeting their testing requirements.

    15See Air Docket # EPA-HQ-OAR-2008-0558-0001.

    In the “Final Rules” section of today'sFederal Register, we are publishing a direct final rule that matches the substance of this proposed rule. If the Agency receives adverse comment or a request for public hearing by January 7, 2009, we will withdraw the direct final rule by publishing a timely withdrawal notice in theFederal Register. If the Agency receives no adverse comment or a request for public hearing by January 7, 2009, these test method changes will be effective sixty (60) days after publication of the final rule in theFederal Register. We are confident that sixty (60) days is sufficient lead time for industry to become familiar and implement these ASTM standard test methods for the applications mentioned above.

    III. Statutory and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and Review

    This action is not a “significant regulatory action” under the terms of Executive Order (EO)12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under the EO.

    B. Paperwork Reduction Act

    This proposed rule does not impose any new information collection burden. However, the Office of Management and Budget (OMB), under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501et seq., has approved the information collection requirements contained in the final RFG and anti-dumping rulemaking and gasoline sulfur control rulemaking, and has assigned OMB control number 2060-0277. OMB, under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501et seq., has also approved the information collection requirements contained in the final Tax Exempt (Dyed) Highway Diesel Fuel rulemaking, and has assigned OMB control number 2060-0308. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

    C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

    For purposes of assessing the impacts of today's proposed rule on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administrations' regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field. The impact of concern is any significantadverseeconomic impact on small entities since the primary purpose of the regulatory flexibility analysis is to identify and address regulatory alternatives “which minimize any significant economicimpact of the rule on small entities.” 5 U.S.C. 603 and 604.

    After considering the economic impacts of today's proposed final rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. In determining whether a rule has a significant economic impact on a substantial number of small entities, the impact of concern is any significantadverseeconomic impact on small entities, since the primary purpose of the regulatory flexibility analyses is to identify and address regulatory alternatives “which minimize any significant economic impact of the rule on small entities.” 5 U.S.C. 603 and 604. Thus an Agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, or otherwise has a positive economic effect on all of the small entities subject to the rule.

    All of the test method updates in this proposed rule will improve the performance and/or utilization by industry of ASTM standard test methods. This proposed rule does not impose a regulatory burden on anyone, including small businesses. Instead, this proposed rule will have a positive impact by improving performance of the industry, including small businesses, by enabling them to use more current voluntary consensus-based standard test methods. In addition, the allowance of ASTM D6550-05 will provide additional flexibility to the regulated community, including small businesses, in meeting olefins in gasoline testing requirements. We have therefore concluded that today's proposed rule will relieve regulatory burden for all effected small entities. We continue to be interested in the potential impacts of the proposed rule on small entities and welcome comments on issues related to such impacts.

    D. Unfunded Mandates Reform Act of 1995 (UMRA)

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531-1538, requires Federal agencies, unless otherwise prohibited by law, to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Federal agencies must also develop a plan to provide notice to small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates and must inform, educate, and advise small governments on compliance with the regulatory requirements.

    This proposed rule does not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any one year. All of the test method updates in today's action will improve the performance and/or utilization by industry of the test methods already allowed by our regulations. The allowance of ASTM D6550-05 will provide additional flexibility to the regulated community in meeting olefins in gasoline testing requirements. Thus, this proposed rule is not subject to the requirements of sections 202 and 205 of the UMRA. This action is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments.

    E. Executive Order 13132: Federalism

    Executive Order 13132, entitled “Federalism” (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.”

    This proposed rule does not have federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. All of the test method updates in today's action will improve the performance and/or utilization by industry of ASTM standard test methods. The allowance of ASTM D6550-05 will provide additional flexibility to the regulated community in meeting olefins in gasoline testing requirements. Thus, Executive Order 13132 does not apply to this proposed rule.

    F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

    This action does not have tribal implications, as specified in Executive Order 13175 (65 FR 67249, November 6, 2000). This action applies to gasoline refiners, blenders and importers that supply gasoline or diesel fuel. All of the test method updates in today's action will improve the performance and/or utilization by industry of the test methods. The allowance of ASTM D6500-05 will provide additional flexibility to the regulated community in meeting olefins in gasoline testing requirements. Thus, Executive Order 13175 does not apply to this action.

    G. Executive Order 13045: Protection of Children From Environmental Health Safety Risk

    EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying only to those regulatory actions that concern health or safety risks, such that the analysis required under section 5-501 of the Executive Order has the potential to influence the regulation. This action is not subject to Executive Order 13045 because it does not establish an environmental standard intended to mitigate health or safety risks.

    H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 (66 FR 18355 (May 22, 2001)) because it is not a significant regulatory action under Executive Order 12866.

    I. National Technology Transfer Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (“NTTAA”), Public Law 104-113, section 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards.

    This proposed rule involves technical standards. EPA will adopt ASTM standards as described in Units II.A, and II.B of theSUPPLEMENTARY INFORMATIONsection of this document. All technical standards included in today's rule are standards developed by ASTM, a voluntary consensus standards body, and thus raises no issues under the NTTAA. The ASTM standards in today's action may be obtained fromASTM International at 100 Barr Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428-2959, 610-832-9585 (phone), 610-832-9555 (fax), orservice@astm.org(e-mail); or through the ASTM Web site (http://www.astm.org).

    J. Executive Order 12898: Federal Actions To Address Environmental Justice and Minority Populations and Low-Income Populations

    Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.

    EPA has determined that this proposed rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it does not affect the level of protection provided to human health or the environment. All of the test method updates in this direct final rule will improve the performance and/or utilization by industry of the test methods. The allowance of ASTM D6500-05 will provide additional flexibility to the regulated community in meeting olefins in gasoline testing requirements. This proposed rule amendment does not relax control measures on sources regulated by the rule and therefore will not cause emission increases from these sources.

    IV. Statutory Provisions and Legal Authority

    Statutory authority for today's proposed rule comes from sections 211(c), 211(i) and 211(k) of the CAA (42 U.S.C. 7545(c) and (k)). Section 211(c) and 211(i) allow EPA to regulate fuels that contribute to air pollution which endangers public health or welfare, or which impairs emission control equipment. Section 211(k) prescribes requirements for RFG and CG and requires EPA to promulgate regulations establishing these requirements. Additional support for the fuels controls in today's proposed rule comes from sections 114(a) and 301(a) of the CAA.
