ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R05-OAR-2017-0165; FRL-9985-13-Region 5]

Air Plan Approval; Ohio; Approval of Sulfur Dioxide Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving Ohio's
revisions to its State Implementation Plan (SIP) for sulfur dioxide
(SO2) under the Clean Air Act (CAA). These revisions update
facility information statewide and add new emission limits for selected
sources in Lake and Jefferson Counties. EPA proposed to approve Ohio's
SIP revision request on August 16, 2018. The revised regulations do not
impose additional emission restrictions except for certain site-
specific provisions which have been included in response to Ohio's
nonattainment area designations of August 5, 2013. EPA received no
adverse comments and is finalizing the approval.

DATES: This final rule is effective on November 13, 2018.

I. Background

II. Public Comment and EPA Response
III. What Action is EPA Taking?
IV. Incorporation by Reference
V. Statutory and Executive Order Reviews

I. Background

    On March 13, 2017, Ohio submitted revisions to the Ohio
Administrative Code Chapter 3745-18 (OAC 3745-18), effective on
February 16, 2017, for incorporation by EPA into the Ohio
SO2 SIP. OAC 3745-18 contains Ohio's air emission
regulations for SO2, which include both generally applicable
requirements and specific SO2 emission limits for each Ohio
county. The revisions update facility information statewide, remove
obsolete emission limits, and add new emission limits for selected
sources in Lake and Jefferson Counties. On August 16, 2018 (83 FR
40723), EPA proposed to approve the submitted revisions. EPA is taking
no action on certain parts of OAC 3745-18-04. EPA received no adverse
public comments on this proposal; see the discussion in section II
below.
    Ohio's March 13, 2017 submittal included rules which Ohio had
developed to address CAA requirements for its 1-hour SO2
nonattainment areas. EPA proposed to approve the revised rules
applicable to Ohio's nonattainment areas because these revisions update
and strengthen the state's SO2 SIP. See section II C of the
August 16, 2018 (83 FR 40723) notice of proposed rulemaking. The
approval of these rules is not intended to address whether Ohio has
fully satisfied EPA's nonattainment planning requirements for the
nonattainment areas. EPA proposed to approve Ohio's nonattainment plan
for the Lake County nonattainment area on August 21, 2018 (83 FR
42235), and intends to address nonattainment planning requirements for
the remaining nonattainment areas in subsequent actions.

II. Public Comment and EPA Response

    The comment period on EPA's August 16, 2018 (83 FR 40723) notice of
proposed rulemaking closed on September 17, 2018. EPA received one
public comment, which generally supported EPA's proposed action. This
comment and EPA's response are described below.
    Comment: The commenter stated that fewer emissions are better
emissions, and advocated the use of silicon for harnessing energy in
solar cells.
    EPA Response: The revised rules do represent a reduction in total
SO2 emissions in Ohio. The remainder of this comment is
beyond the scope of EPA's action on Ohio's submittal.

III. What action is EPA taking?

    EPA is approving Ohio's March 13, 2017 submittal of OAC 3745-18-01;
OAC 3745-18-03; and OAC 3745-18-04

[except OAC 3745-18-04(D)(2), (D)(3), (D)(5), (D)(6), and (D)(9)(c),
and OAC 3745-18-04 (E)(2), (E)(3) and (E)(4)]. EPA is also approving
OAC 3745-18-05 and OAC 3745-18-07 through OAC 3745-18-94. Ohio's
adoption of these rules was effective on February 16, 2017. EPA is
taking no action on OAC 3745-18-04(D)(2), (D)(3), (D)(5), (D)(6), and
(D)(9)(c), and OAC 3745-18-04 (E)(2), (E)(3) and (E)(4). EPA is also
removing OAC 3745-18-02 from the Ohio SO2 SIP, pursuant to
Ohio's request of September 10, 2009 \1\. In the codification of this
rule, besides specifying the approved rules in 40 CFR 52.1870, EPA is
also removing text in 40 CFR 52.1881 that provided a duplicated and
outdated listing of approved and disapproved Ohio rules.
---------------------------------------------------------------------------

    \1\ Correction: The August 16, 2018 (83 FR 40723) notice of
proposed rulemaking erroneously gave Ohio's 2009 SIP revision
submittal date as September 17, 2009. Ohio's submittal requesting
the removal of 3745-18-02 was dated September 10, 2009.
---------------------------------------------------------------------------

IV. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with requirements of 1 CFR
51.5, EPA is finalizing the incorporation by reference of the Ohio
regulations described in the amendments to 40 CFR part 52 set forth
below. EPA has made, and will continue to make, these documents
generally available through www.regulations.gov and at the EPA Region 5
Office (please contact the person identified in the FOR FURTHER
INFORMATION CONTACT section of this preamble for more information).
Therefore, these materials have been approved by EPA for inclusion in
the State implementation plan, have been incorporated by reference by
EPA into that plan, are fully federally enforceable under sections 110
and 113 of the CAA as of the effective date of the final rulemaking of
EPA's approval, and will be incorporated by reference in the next
update to the SIP compilation.\2\

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

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the CAA. Accordingly, this
action merely approves state law as meeting Federal requirements and
does not impose additional requirements beyond those imposed by state
law. For that reason, this action:
     Is not a significant regulatory action subject to review
by the Office of Management and Budget under Executive Orders 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2,
2017) regulatory action because SIP approvals are exempted under
Executive Order 12866;
     Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
     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);
     Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
     Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
     Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where EPA or an Indian tribe has
demonstrated that a tribe has jurisdiction. In those areas of Indian
country, the rule does not have tribal implications and will not impose
substantial direct costs on tribal governments or preempt tribal law as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
    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 action 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 CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by December 10, 2018. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this action 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).)

	OFFICE OF                                                               AIR AND RADIATION

George (Tad) S. Aburn, Jr. Director, Air and Radiation Administration Maryland Department of the Environment 1800 Washington Boulevard Baltimore, MD 21230

Dear Mr. Aburn:

      Thank you for your letter dated January 28, 2021 in which you request that the U.S. Environmental Protection Agency (EPA) extend the comment period for the above EPA notice by 30 days.

      The Agency will grant the request for the extension and will publish a notice in the Federal Register announcing the extension. EPA is extending the comment period for the following reasons: (1) the legal and technical complexity of the analysis of the recommendation; (2) the need for stakeholders to consider the interaction of this decision with other actions the Agency is concurrently considering; (3) the stakeholders' need for additional time to review and develop constructive comments and related analyses on the recommendation.

      Again, thank you for your letter.  I appreciate the opportunity to be of service and trust the information provided is helpful.

                              Sincerely,

                              Christopher Grundler  						Director, Office of Atmospheric Programs
