    SUMMARY: The EPA is proposing to disapprove a revision to Michigan's 
    State Implementation Plan (SIP) which would change the State's 
    definition of volatile organic compound (VOC). The Michigan Department 
    of Environmental Quality (MDEQ) submitted this revision on August 20, 
    1998 and supplemented it with a November 3, 1998, letter.
    
    DATES: Comments on this proposed action must be received by July 12, 
    1999.

    A. Background Information
    B. Contents of State Submittal and EPA's Evaluation
    C. EPA's Proposed Action
    
    A. Background
    
        On August 20, 1998, the MDEQ submitted to EPA a proposed revision 
    to the Michigan SIP. MDEQ supplemented the proposed revision with a 
    November 3, 1998, letter from Robert Irvine. The submittal included a 
    revision to the State's definition of VOC, as well as other rule 
    revisions and rescissions. In this document EPA is proposing action 
    only on the revision to the definition of VOC, R 336.1122(f). We will 
    address the remaining rule revisions and rescissions in separate 
    rulemaking actions.
    
    B. Contents of State Submittal and EPA's Evaluation
    
        The State's definition of the term ``volatile organic compound'' is 
    ``any compound of carbon, or mixture of compounds of carbon that 
    participates in photochemical reactions, excluding the following 
    materials, all of which do not contribute appreciably to the formation 
    of ozone: * * * *'' The definition goes on to list the exempt 
    compounds. The wording of the State definition is ambiguous, in that it 
    could
    
    [[Page 31169]]
    
    imply that there are compounds, other than those listed, which arguably 
    do not ``participate in photochemical reactions,'' and therefore may be 
    excluded from the definition of VOC. Instead, the State should define 
    the term VOC as all organic compounds except those that EPA has listed 
    as negligibly photochemically reactive. (See 40 CFR 51.100(s).) As 
    worded, the definition is unacceptable.
        The State has added the following substances as materials excluded 
    from the State definition of VOC: acetone; cyclic, branched, or linear 
    completely-methylated siloxanes; parachlorobenzotriflouride; 
    trichlorofluoromethane (CFC-11); dichlorodifluoromethane (CFC-12); 
    1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113); 1,2-dichloro 1,1,2,2-
    tetrafluoroethane (CFC-114); chloropentafluoroethane (CFC-115); 1,1-
    dichloro 1-fluoroethane (HCFC-141b); 1-chloro 1,1-difluoroethane (HCFC-
    142b); chlorodifluoromethane (HCFC-22); 1,1,1-trifluoro 2,2-
    dichloroethane (HCFC-123); 2-chloro-1,1,1,2-tetrafluoroethane (HCFC-
    124); trifluoromethane (HFC-23); pentafluoroethane (HFC-125); 1,1,2,2-
    tetrafluoroethane (HFC-134); 1,1,1,2-tetrafluoroethane (HFC-134a); 
    1,1,1-trifluoroethane (HFC-143a); 1,1-difluoroethane (HFC-152a); and 
    perfluorocarbon compounds which fall into these classes: cyclic, 
    branched, or linear, completely fluorinated alkanes; cyclic, branched, 
    or linear, completely fluorinated ethers with no unsaturations; cyclic, 
    branched, or linear, completely fluorinated tertiary amines with no 
    unsaturations; and sulfur containing perfluorocarbons with no 
    unsaturations and with sulfur bonds only to carbon and fluorine. These 
    compounds are on the list of compounds exempted from the Federal 
    definition of VOC in 40 CFR 51.100(s), and their exclusion is 
    acceptable.
        In addition to the compounds listed above, however, the State has 
    included as an exempt compound, ``ingredient compounds in materials 
    other than surface coatings that have a vapor pressure less than or 
    equal to 0.1 millimeters of mercury at the temperature at which they 
    are used.'' This is unacceptable because it contradicts established EPA 
    policy and is inconsistent with the Federal definition of VOC found in 
    40 CFR 51.100(s).
        In the past, MDEQ has cited EPA's similar treatment of certain VOCs 
    in our Consumer Products rule to justify its proposed change. However, 
    we noted in our proposed Consumer Products rule (61 FR 14531) that the 
    we adopted the volatility threshold specifically for consumer products, 
    to differentiate between products containing ingredients with higher 
    volatility. Many consumer products would contain 100 percent VOC by 
    definition, making all of them subject to rules designed to reduce VOCs 
    from consumer products, unless we devised a means to distinguish them. 
    To address this problem, we examined the possibility of targeting only 
    those consumer products with relatively higher volatility. We also 
    noted in the proposed rule for Consumer Products that it did not alter 
    our overall VOC policy, which does not allow vapor pressure cutoffs, 
    such as 0.1 mm Hg, to exempt compounds from the definition of VOC. 
    Thus, the proposed Consumer Products rule did not redefine VOC, it 
    proposed to adopt an applicability threshold based on pressure for that 
    specific source category only.
        Michigan has proposed a change to the definition of VOC which would 
    allow the State to use ``other methods and procedures acceptable to the 
    department'' to determine compliance with emission limits if the 
    methods listed in rules 336.2004 and 336.2040 do not result in accurate 
    or reliable results. This represents unacceptable State discretion. The 
    State must submit any change in test methods to EPA for our approval as 
    a SIP revision.
    
    C. EPA's Proposed Action
    
        To determine a rule's approvability, we must evaluate the rule for 
    consistency with the requirements of the Clean Air Act, EPA regulations 
    and the our interpretation of these requirements as expressed in EPA 
    policy guidance documents. We have found Michigan's proposed SIP 
    revision to be inconsistent with the Federal definition of VOC in 40 
    CFR 51.100(s). The proposed revision is also inconsistent with EPA 
    policy guidance documents, including: ``Issues Relating to VOC 
    Regulation Cutpoints, Deficiencies and Deviations, Clarification to 
    Appendix D of November 24, 1987 Federal Register Notice'' dated May 25, 
    1988; EPA's policy memorandum dated June 8, 1989, from G. T. Helms, 
    Chief, Ozone/Carbon Monoxide Programs Branch, entitled ``Definition of 
    VOC: Rationale;'' EPA's policy memorandum dated April 17, 1987, from G. 
    T. Helms, Chief, Control Programs Operations Branch, entitled 
    ``Definition of VOC;'' and EPA's policy memorandum dated April 17, 
    1987, from G. T. Helms, Chief, Control Programs Operations Branch, 
    entitled ``Definition of Volatile Organic Compounds (VOC's).'' 
    Therefore, we are proposing to disapprove Michigan's SIP revision 
    request.
    
    II. Administrative Requirements
    
    A. Executive Order 12866
    
        The Office of Management and Budget (OMB) has exempted this 
    regulatory action from Executive Order (E.O.) 12866, entitled 
    ``Regulatory Planning and Review.''
    
    B. Executive Order 12875
    
        Under E.O. 12875, EPA may not issue a regulation that is not 
    required by statute and that creates a mandate upon a state, local or 
    tribal government, unless the Federal government provides the funds 
    necessary to pay the direct compliance costs incurred by those 
    governments. If the mandate is unfunded, EPA must provide to the OMB a 
    description of the extent of EPA's prior consultation with 
    representatives of affected State, local and tribal governments, the 
    nature of their concerns, copies of any written communications from the 
    governments, and a statement supporting the need to issue the 
    regulation. In addition, E.O. 12875 requires EPA to develop an 
    effective process permitting elective officials and other 
    representatives of State, local and tribal governments ``to provide 
    meaningful and timely input in the development of regulatory proposals 
    containing significant unfunded mandates.'' This rule does not create a 
    mandate on state, local or tribal governments. The rule does not impose 
    any enforceable duties on these entities. Accordingly, the requirements 
    of section 1(a) of E.O. 12875 do not apply to this rule.
    
    C. Executive Order 13045
    
        Protection of Children from Environmental Health Risks and Safety 
    Risks (62 FR 19885, April 23, 1997), applies to any rule that: (1) is 
    determined to be ``economically significant'' as defined under E.O. 
    12866, and (2) concerns an environmental health or safety risk that EPA 
    has reason to believe may have a disproportionate effect on children. 
    If the regulatory action meets both criteria, the Agency must evaluate 
    the environmental health or safety effects of the planned rule on 
    children, and explain why the planned regulation is preferable to other 
    potentially effective and reasonably feasible alternatives considered 
    by the Agency.
        This rule is not subject to E.O. 13045 because it is does not 
    involve decisions intended to mitigate environmental health or safety 
    risks.
    
    [[Page 31170]]
    
    D. Executive Order 13084
    
        Under E.O. 13084, EPA may not issue a regulation that is not 
    required by statute, that significantly affects or uniquely affects the 
    communities of Indian tribal governments, and that imposes substantial 
    direct compliance costs on those communities, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by the tribal governments. If the mandate is unfunded, 
    EPA must provide to the OMB, in a separately identified section of the 
    preamble to the rule, a description of the extent of EPA's prior 
    consultation with representatives of affected tribal governments, a 
    summary of the nature of their concerns, and a statement supporting the 
    need to issue the regulation. In addition, E.O. 13084 requires EPA to 
    develop an effective process permitting elected officials and other 
    representatives of tribal governments ``to provide meaningful and 
    timely input in the development of regulatory policies on matters that 
    significantly or uniquely affect their communities.'' This rule does 
    not significantly or uniquely affect the communities of Indian tribal 
    governments. Accordingly, the requirements of section 3(b) of E.O. 
    13084 do not apply to this rule.
    
    E. Regulatory Flexibility
    
        The Regulatory Flexibility Act (RFA) generally requires an agency 
    to conduct a regulatory flexibility analysis of any rule subject to 
    notice and comment rulemaking requirements 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 not-for-profit enterprises, and small governmental 
    jurisdictions. EPA's disapproval of the State request under Section 110 
    and subchapter I, part D of the Clean Air Act does not affect any 
    existing requirements applicable to small entities. Any pre-existing 
    Federal requirements remain in place after this disapproval. Federal 
    disapproval of the state submittal does not affect its state 
    enforceability. Moreover, EPA's disapproval of the submittal does not 
    impose any new Federal requirements. Therefore, EPA certifies that this 
    disapproval action does not have a significant impact on a substantial 
    number of small entities because it does not remove existing 
    requirements and impose any new Federal requirements
    
    F. Unfunded Mandates
    
        Under section 202 of the Unfunded Mandates Reform Act of 1995 
    (``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
    must prepare a budgetary impact statement to accompany any proposed or 
    final rule that includes a Federal mandate that may result in estimated 
    annual costs to State, local, or tribal governments in the aggregate; 
    or to private sector, of $100 million or more. Under section 205, EPA 
    must select the most cost-effective and least burdensome alternative 
    that achieves the objectives of the rule and is consistent with 
    statutory requirements. Section 203 requires EPA to establish a plan 
    for informing and advising any small governments that may be 
    significantly or uniquely impacted by the rule.
        The EPA has determined that the disapproval action proposed does 
    not include a Federal mandate that may result in estimated annual costs 
    of $100 million or more to either State, local, or tribal governments 
    in the aggregate, or to the private sector. This Federal disapproval 
    action imposes no new requirements. Accordingly, no additional costs to 
    State, local, or tribal governments, or to the private sector, result 
    from this action.
