Approval and Promulgation of Implementation Plans; Michigan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The EPA is partially approving and partially disapproving 
revisions to the Michigan State Implementation Plan (SIP). These 
revisions were submitted to the EPA by the Michigan Department of 
Environmental Quality (MDEQ) on April 3, 2003, May 28, 2003, September 
17, 2004, October 25, 2004 and June 8, 2005. The following sections of 
Michigan's rules are affected: Part 3: Emission Limitations and 
Prohibitions--Particulate Matter; Part 4: Emission Limitations and 
Prohibitions--Sulfur-bearing Compounds; Part 6: Emission Limitations 
and Prohibitions--Existing Sources of Volatile Organic Compound 
Emissions; Part 7: Emission Limitations and Prohibitions--New Sources 
of Volatile Organic Compound Emissions; Part 9: Emission Limitations 
and Prohibitions--Miscellaneous; Part 10: Intermittent Testing and 
Sampling; and Part 11: Continuous Emission Monitoring. The revisions 
are primarily administrative changes and minor corrections. EPA's 
proposed partial approval and partial disapproval was published on 
December 29, 2005.

DATES: This final rule is effective on July 3, 2006.

I. What Is the Background for This Rule?

    On April 3, 2003, May 28, 2003, September 17, 2004, October 25, 
2004, and June 8, 2005 the MDEQ submitted revisions to the Michigan 
SIP. These submissions revise the following sections of Michigan's Air 
Pollution Control Rules: R 336.1301, R 336.1303, R 336.1330, R 336.1331 
except item C8 of Table 31, R 336.1358, R 336.1361, R 336.1362, R 
336.1363, R 336.1371, R 336.1372, R 336.1374, R 336.1401, R 336.1403, R 
336.1601, R 336.1602, R 336.1604 to R 336.1608, R 336.1615 to R 
336.1619, R 336.1622, R 336.1623, R 336.1625, R 336.1627 to R 336.1631, 
R 336.1702, R 336.1705, R 336.1906, R 336.1911, R 336.1930, R 336.2001 
to R 336.2005, R 336.2007, R 336.2011 to R 336.2014, R 336.2021, R 
336.2040 except subrules (9) and (10), R 336.2041, R 336.2101, R 
336.2150, R 336.2155, R 336.2159, R 336.2170, R 336.2175, R 336.2189, 
and R 336.2190. The revisions are primarily administrative changes and 
minor corrections.
    On December 29, 2005 (70 FR 77113), we proposed to partially 
approve and partially disapprove the State's submittal. We proposed to 
disapprove Rules R 336.1602 and R 336.2041 and to approve the remainder 
of the rules submitted by the State. The rationale for EPA's proposed 
action is explained in the notice of proposed rulemaking and will not 
be restated here.

II. What Comments Did We Receive and What Are Our Responses?

    This section summarizes the comments submitted during the public 
comment period for the notice of proposed rulemaking and provides EPA's 
response to those comments. The comment period closed January 30, 2006. 
Adverse comments were received from the MDEQ.
    Comment: The proposed Rule 602 revisions are appropriate and 
necessary to conform to the current version of Rule 610. Further, EPA's 
concern about eliminating the approved references should not be an 
issue because the version of Rules 602 and 610 that are approved in the 
SIP contain identical language as the current MDEQ Rules 602 and 610 in 
the specific subrules in question. The revisions being made to Rule 602 
are simply changing the Rule 610 references to align with numbering 
changes to the relevant subrules in Rule 610. The fact that there are 
some other portions of MDEQ's current Rule 610 that are not approved by 
EPA and in the SIP should not impact the specific revisions that EPA is 
proposing to disapprove.
    Response: Rule R 336.1602 (Rule 602) contains general provisions 
for sources of volatile organic compound (VOC) emissions. Rule R 
336.1610 (Rule 610) regulates VOC emissions from coating lines. These 
rules were submitted by Michigan and approved by EPA pursuant to the 
Reasonably Available Control Technology (RACT) requirements of sections 
182(a)(2)(A) and (b)(2) of the Clean Air Act (CAA). See 59 FR 46182. 
Further, MDEQ has made revisions to the state version of R 336.1610 
which EPA has not approved into the SIP, and which are not currently 
before EPA for review.
    In reviewing the revisions to Rule 602 that MDEQ has submitted for 
approval into the SIP, EPA must evaluate their impact on the version of 
Rule 610 currently approved into the SIP. With respect to the SIP, the 
non-SIP approved, non-federally enforceable state version of Rule 610 
is irrelevant. Further, the versions of Rules 602 and 610 currently 
approved into the SIP do not contain identical language to the versions 
currently effective at the state level.
    The SIP approved version of Rule 602 requires any approval of 
equivalent emission rates, alternate emission rates, or compliance 
methods that are authorized pursuant to R 336.1610(7)(a) or R 
336.1610(14), table 63, to be submitted to EPA as a revision to the 
SIP. Correspondingly, R 336.1610(7)(a) allows the state to ``authorize 
compliance to be based upon a longer averaging period, which shall not 
be more than 1 calendar month.'' R 336.1610(14) table 63 (Column B--
transfer efficiency) allows credit for greater transfer efficiencies, 
with state approval of the transfer efficiency test method. It is the 
references to Rule 610 in Rule 602 that require these deviations to be 
submitted to EPA as a revision to the SIP.
    If the changes to Rule 602 were approved by EPA as a revision to 
Michigan's SIP, the state would then be required to submit any approval 
of equivalent emission rates, alternate emission rates, or compliance 
methods that are authorized pursuant to sections R 336.1610(5)(a) or R 
336.1610(11), table 63, to EPA as revisions to the SIP. However, in the 
version of Rule 610 contained in the SIP, R 336.1610(5)(a) requires 
sources to submit a written program for compliance with Rule 610, and 
there is no table 63 in R 336.1610(11). Neither section contains 
provisions authorizing approval of equivalent emission rates, alternate 
emission rates, or compliance methods. Further, the deviations allowed 
under SIP-approved R 336.1610(7)(a) and R 336.1610(14), table 63, would 
no longer be required to be submitted to EPA as revisions to the SIP.
    As articulated in EPA's December 29, 2005 proposal, approval of the 
revision to R 336.1602 would relax RACT by allowing the State to alter 
the SIP without EPA review and approval (director's discretion). This 
is inconsistent with the requirements of the CAA and with RACT 
requirements as set forth in 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. For this reason, EPA is 
disapproving the revisions to R 336.1602.
    Comment: The MDEQ agrees that language was added to subrule (1) of 
R 336.2041 (Rule 1041) that could allow recordkeeping requirements to 
be accepted by the MDEQ that are not SIP-approved. This was added to 
address any existing orders, agreements, contracts or rules that 
contain recordkeeping provisions but are not made part of the SIP. The 
intent was to prevent the unacceptable burden to these sources of 
having to revise previously approved recordkeeping provisions to fit 
the new Rule 1041 provisions. All recordkeeping in orders, agreements, 
contracts, or rules that are initiated after Rule 1041 became effective 
would be expected to follow the requirements in Rule 1041. EPA should 
accept the language in subrule (1) and approve it into the SIP.
    Response: It should be noted that Rule 1041 was submitted by 
Michigan and approved by EPA pursuant to the RACT requirements of 
sections 182(a)(2)(A) and (b)(2) of the CAA. See 59 FR 46182.
    In revising Rule 1041, it may have been the intention of MDEQ to 
allow recordkeeping flexibility only for those sources subject to 
orders, agreements, contracts or rules containing recordkeeping 
provisions which had been approved prior to adoption of Rule 1041 in 
1993, but not regulated under the SIP. However, these limitations are 
not set forth in the rule. As written, the revised rule would allow the 
State to alter recordkeeping requirements for sources subject to the 
SIP and therefore alter the SIP without EPA review and approval.
    This is inconsistent with the requirements of the CAA and with RACT 
requirements as set forth in EPA policy guidance documents, including 
``Issues Relating to VOC Regulation Cutpoints, Deficiencies and 
Deviations, Clarification to Appendix D of November 24, 1987 Federal 
Register

[[Page 31095]]

Notice'' dated May 25, 1988. For this reason, Rule 1041, as revised, is 
not approvable.
    Comment: MDEQ recognizes that there may be provisions in Rule 1041 
that impact portions of Rule 610 that are not approved into the SIP, 
but requests that EPA specifically identify these provisions. MDEQ also 
requests that EPA approve any portions of Rule 1041 that reference 
parts of Rule 610 that have basically remained the same in the earlier 
SIP-approved version of Rule 610 and the revised version.
    Response: In reviewing the revisions to Rule 1041, EPA must 
evaluate their impact on the version of Rule 610 currently approved 
into the SIP. With respect to the SIP, the non-SIP approved, non-
federally enforceable state version of Rule 610 is irrelevant. The 
problem noted in EPA's December 29, 2005 proposal is that Rule 1041 was 
revised to state that sources:

subject to emission limits in R 336.1610(11), table 62 shall keep 
records as required in the publication entitled ``Protocol for 
Determining the Daily Volatile Organic Compound Emission Rate of 
Automobile and Light-duty Truck Topcoat Operations,'' EPA-450/3-88-
018, December, 1988, which is referenced in R 336.1610(6)(b).

In the SIP approved version of Rule 610, there is no table 62 in 
subpart 11, and the publication noted is not referenced in subsection 
(6)(b). The revisions are confusing and inconsistent with the SIP.
    Comment: The MDEQ requested that EPA specifically identify 
rewording in Rule 1041 that is confusing.
    Response: The wording of subsections (2), (3), (4), (5), (6), (7), 
(8), (9), (10), (11), and (12) is confusing. Each subsection begins 
with similar language. For example, subsection (2) states:

    If a coating line does not have an add-on emissions control 
device for which emission limits are expressed in pounds of volatile 
organic compounds per gallon of coating, minus water, as applied, 
and if only 1 coating is used on the coating line during the 
averaging time, then a person shall keep records. * * *

 .It is not clear from the wording of the rule if the emission limits 
referred to are coating line emission limits or control device emission 
limits. If the intention is that the emission limits, and the units in 
which they are expressed, refer to the coating line, clearer wording is 
advisable. For example, the requirement could be expressed as follows:

    If a coating line for which emission limits are expressed in 
pounds of volatile organic compounds per gallon of coating, minus 
water, as applied, does not have an add-on emissions control device, 
and if only 1 coating is used on the coating line during the 
averaging time, then a person shall keep records. * * *.

III. What Action Is EPA Taking?

    To determine the approvability of a rule, EPA must evaluate the 
rule for consistency with the requirements of the CAA, EPA regulations 
and the EPA's interpretation of these requirements as expressed in EPA 
policy guidance documents. While we understand the concerns raised by 
MDEQ, Rules R 336.1602 and R 336.2041 remain inconsistent with the CAA 
and the applicable policies by which EPA must evaluate submittals, 
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. Therefore, EPA is 
finalizing its disapproval of rules R 336.1602 and R 336.2041. We are 
also finalizing our approval of the remainder of the rules submitted by 
the State.

IV. Statutory and Executive Order Reviews

Executive Order 12866: Regulatory Planning and Review

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget.

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

    Because it is not a ``significant regulatory action'' under 
Executive Order 12866 or a ``significant energy action,'' this action 
is also not subject to Executive Order 13211, ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001).

Regulatory Flexibility Act

    This action merely approves state law as meeting Federal 
requirements and imposes no additional requirements beyond those 
imposed by state law. Accordingly, the Administrator certifies that 
this rule will not have a significant economic impact on a substantial 
number of small entities under the Regulatory Flexibility Act (5 U.S.C. 
601 et seq.).

Unfunded Mandates Reform Act

    Because this rule approves pre-existing requirements under state 
law and does not impose any additional enforceable duty beyond that 
required by state law, it does not contain any unfunded mandate or 
significantly or uniquely affect small governments, as described in the 
Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

Executive Order 13175: Consultation and Coordination With Indian Tribal 
Governments

    This rule also does not have tribal implications because it will 
not have a substantial direct effect on one or more Indian tribes, on 
the relationship between the Federal Government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000).

Executive Order 13132: Federalism

    This action also does not have Federalism implications because it 
does 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 (64 FR 43255, August 
10, 1999). This action merely approves a state rule implementing a 
Federal standard, and does not alter the relationship or the 
distribution of power and responsibilities established in the Clean Air 
Act.

Executive Order 13045: Protection of Children From Environmental Health 
and Safety Risks

    This rule also is not subject to Executive Order 13045 ``Protection 
of Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997), because it is not economically significant.

National Technology Transfer Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (NTTA), 15 U.S.C. 272, requires Federal agencies to use 
technical standards that are developed or adopted by voluntary 
consensus to carry out policy objectives, so long as such standards are 
not inconsistent with applicable law or otherwise impracticable. In 
reviewing program submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the Act. Absent a prior 
existing requirement for the state to use voluntary consensus 
standards, EPA has no authority to disapprove a program submission for 
failure to use such standards, and it would thus be inconsistent with 
applicable law for EPA to use voluntary consensus standards in place of 
a program submission that otherwise satisfies the

[[Page 31096]]

provisions of the Act. Therefore, the requirements of section 12(d) of 
the NTTA do not apply.

Paperwork Reduction Act

    This rule does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 
et seq.).

Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by July 31, 2006. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule for the purposes of judicial 
review nor does it extend the time within which a petition for judicial 
review may be filed, and shall not postpone the effectiveness of such 
rule or action. This action may not be challenged later in proceedings 
to enforce its requirements. (See Section 307(b)(2).)
