40 CFR Part 55

[EPA-R03-OAR-2021-0767; FRL-9366-02-R3]


Outer Continental Shelf Air Regulations; Consistency Update for 
Virginia

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is updating a 
portion of the Outer Continental Shelf (OCS) Air Regulations. 
Requirements applying to OCS sources located within 25 miles of states' 
seaward boundaries must be updated periodically to remain consistent 
with the requirements of the corresponding onshore area (COA), as 
mandated by the Clean Air Act (CAA). The portion of the OCS air 
regulations that is being updated pertains to the requirements for OCS 
sources for which Virginia is the designated COA. The Commonwealth of 
Virginia's requirements discussed in this document will be incorporated 
by reference into the Code of Federal Regulations (CFR) and listed in 
the appendix to the Federal OCS air regulations.

DATES: This final rule is effective on November 22, 2023. The 
incorporation by reference of certain publications listed in this rule 
is approved by the Director of the Federal Register as of November 22, 
2023.

ADDRESSES: EPA has established a docket for this action under Docket ID 
Number EPA-R03-OAR-2021-0767. All documents in the docket are listed on

I. Background and Purpose

    On September 4, 1992, EPA promulgated 40 CFR part 55,\1\ which 
established requirements to control air pollution from OCS sources in 
order to attain and maintain Federal and state ambient air quality 
standards and to comply with the provisions of part C of title I of the 
CAA. The regulations at 40 CFR part 55 apply to all OCS sources 
offshore of the states except those located in the Gulf of Mexico west 
of 87.5 degrees longitude. Section 328 of the CAA requires that for 
such sources located within 25 miles of a state's seaward boundary, the 
requirements shall be the same as would be applicable if the sources 
were located in the COA. Because the OCS requirements are based on 
onshore requirements, and onshore requirements may change, section 
328(a)(1) requires that EPA update the OCS requirements as

[[Page 72692]]

necessary to maintain consistency with onshore requirements.
---------------------------------------------------------------------------

    \1\ The reader may refer to the notice of proposed rulemaking, 
December 5, 1991 (56 FR 63774), and the preamble to the final rule 
promulgated September 4, 1992 (57 FR 40792), for further background 
and information on the OCS regulations.
---------------------------------------------------------------------------

    On February 10, 2022 (87 FR 7790), EPA published a notice of 
proposed rulemaking (NPRM) proposing to incorporate various Virginia 
air pollution control requirements into 40 CFR part 55. Pursuant to 40 
CFR 55.12, consistency reviews will occur: (1) at least annually; (2) 
upon receipt of a Notice of Intent (NOI) under 40 CFR 55.4; or (3) when 
a state or local agency submits a rule to EPA to be considered for 
incorporation by reference in 40 CFR part 55. EPA's NPRM proposed to 
approve an annual update pursuant to 40 CFR 55.12(b). Subsequent to 
EPA's February 10, 2022, NPRM, Virginia amended state regulations 
relevant to the OCS, effective March 15, 2023. EPA intends to address 
these post-NPRM state amendments in its next annual update consistent 
with 40 CFR 55.12. This action addresses only those regulations 
identified for incorporation in NPRM, namely the Virginia regulations 
that were updated as of September 8, 2021.
    EPA reviewed the Virginia Department of Environmental Quality 
(``Virginia DEQ'') air rules for inclusion in 40 CFR part 55 in this 
action to ensure that they are rationally related to the attainment or 
maintenance of Federal or state ambient air quality standards and 
compliance with part C of title I of the CAA, that they are not 
designed expressly to prevent exploration and development of the OCS, 
and that they are potentially applicable to OCS sources. See 40 CFR 
55.1. EPA has also evaluated the rules to ensure they are not arbitrary 
or capricious. See 40 CFR 55.12(e). In addition, EPA has excluded 
administrative or procedural rules,\2\ and requirements that regulate 
toxics which are not related to the attainment and maintenance of 
Federal and state ambient air quality standards.
---------------------------------------------------------------------------

    \2\ Each COA which has been delegated the authority to implement 
and enforce part 55 will use its administrative and procedural rules 
as onshore. However, in those instances where EPA has not delegated 
authority to implement and enforce 40 CFR part 55, EPA will use its 
own administrative and procedural requirements to implement the 
substantive requirements. See 40 CFR 55.14(c)(4).
---------------------------------------------------------------------------

    Section 328(a) of the CAA requires that EPA establish requirements 
to control air pollution from OCS sources located within 25 miles of 
states' seaward boundaries that are the same as onshore requirements. 
To comply with this statutory mandate, EPA must incorporate applicable 
onshore rules into 40 CFR part 55 as they exist onshore. This limits 
EPA's flexibility in deciding which requirements will be incorporated 
into 40 CFR part 55 and prevents EPA from making substantive changes to 
the requirements it incorporates. As a result, EPA may be incorporating 
rules into 40 CFR part 55 that do not conform to all of EPA's state 
implementation plan (SIP) guidance or certain requirements of the CAA. 
Consistency updates may result in the inclusion of state or local rules 
or regulations into 40 CFR part 55, even though the same rules may 
ultimately be disapproved for inclusion as part of the SIP. Inclusion 
in the OCS rule does not imply that a rule meets the requirements of 
the CAA for SIP approval, nor does it imply that the rule will be 
approved by EPA for inclusion in the SIP.
    The specific requirements of the consistency update and the 
rationale for EPA's action are explained in the February 10, 2022, 
NPRM. No comments were received on the NPRM.

II. Public Comments and EPA Responses

    EPA did not receive any comments on the February 10, 2022, NPRM, 87 
FR 7790.

III. Final Action

    EPA is taking final action to incorporate the rules potentially 
applicable to OCS sources for which the Commonwealth of Virginia will 
be the COA. The rules that EPA is taking final action to incorporate 
are applicable provisions of the Virginia Administrative Code (VAC). 
The Virginia regulatory changes that EPA is taking final action to 
incorporate are (1) Chapter 20, General Provisions-- 9VAC5-20-21, 
Documents incorporated by reference; (2) Chapter 50, New and Modified 
Stationary Sources--9VAC5-50-400. General; (3) Chapter 60, Hazardous 
Air Pollutant Sources--9VAC5-60-60. General; (4) Chapter 60, Hazardous 
Air Pollutant Sources--9VAC5-60-90, as amended through September 8, 
2021. The rules that EPA is taking final action to incorporate will 
replace the rules identified in the February 10, 2022, NPRM and 
previously incorporated into ``Commonwealth of Virginia Requirements 
Applicable to OCS Sources,'' dated February 20, 2019. See 84 FR 56121; 
October 21, 2019. This action will have no effect on any provisions 
that were not subject to changes by Virginia and were also previously 
incorporated by reference into 40 CFR part 55 through EPA's October 21, 
2019 (84 FR 56121) final rule.

IV. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with the requirements of 1 
CFR 51.5, EPA is finalizing the incorporation by reference of 
``Commonwealth of Virginia Requirements Applicable to OCS Sources,'' 
dated September 8, 2021, which provides the text of the Virginia DEQ 
air rules in effect as of September 8, 2021, that would apply to OCS 
sources. EPA has made, and will continue to make, these materials 
available through www.regulations.gov and at the EPA Region III Office 
(please contact the person identified in the FOR FURTHER INFORMATION 
CONTACT section of this preamble for more information).

V. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to establish 
requirements to control air pollution from OCS sources located within 
25 miles of states' seaward boundaries that are the same as onshore air 
pollution control requirements. To comply with this statutory mandate, 
EPA must incorporate applicable onshore rules into 40 CFR part 55 as 
they exist onshore. See 42 U.S.C. 7627(a)(1); 40 CFR 55.12. Thus, in 
promulgating OCS consistency updates, EPA's role is to maintain 
consistency between OCS regulations and the regulations of onshore 
areas, provided that they meet the criteria of the CAA. Accordingly, 
this action simply updates the existing OCS requirements to make them 
consistent with requirements onshore, without the exercise of any 
policy direction by EPA. 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);
     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

[[Page 72693]]

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); and
     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.
    Additionally, Executive Order 12898 (59 FR 7629, February 16, 1994) 
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 (people of color and/
or Indigenous peoples) and low-income populations.
    EPA believes that this specific action does not concern human 
health or environmental conditions and therefore cannot be evaluated 
with respect to potentially disproportionate and adverse effects on 
people of color, low-income populations and/or Indigenous peoples. This 
action simply fulfills EPA's statutory mandate to ensure regulatory 
consistency between the COA and inner OCS consistent with the stated 
objectives of CAA section 328(a)(1). Specifically, section 328(a)(1) 
requires EPA to establish requirements to control air pollution from 
OCS sources ``to attain and maintain Federal and State ambient air 
quality standards and to comply with the provisions of part C of [title 
I of the CAA]'' and, for inner OCS sources (located within 25 miles of 
the seaward boundary of such states), to establish requirements that 
are ``the same as would be applicable if the source were located in the 
COA.'' This section of the Act also states that ``the Administrator 
shall update such requirements as necessary to maintain consistency 
with onshore regulations and this chapter.'' As noted in the preamble, 
compliance with this requirement limits EPA's discretion in deciding 
what will be incorporated into 40 CFR part 55.
    From the time of EPA's last consistency update for Virginia (84 FR 
56121, October 21, 2019) to the publication of the NPRM (87 FR 7790, 
February 10, 2022), state regulations relevant to the OCS were simply 
amended to update references to the CFR. This action incorporates into 
the CFR those minor updates to state regulations, which are already 
effective onshore, to ensure regulatory consistency with the COA as 
mandated by CAA section 328(a)(1). This is a routine and ministerial 
consistency update that does not directly affect any human health or 
environmental conditions in the commonwealth of Virginia. In addition, 
EPA provided for meaningful public involvement on this rule through the 
notice and comment process, through which EPA received no comments. 
This rule was in addition to the State-level notice and comment process 
held by Virginia.
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because it does 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, nor does it impose 
substantial direct compliance costs on tribal governments or preempt 
tribal law.
    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 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 December 22, 2023. 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).).
    This action does not impose any new information collection burden 
under the Paper Reduction Act (PRA). See 44 U.S.C 3501. The Office of 
Management and Budget (OMB) has previously approved the information 
collection activities contained in the existing regulations at 40 CFR 
part 55 and, by extension, this update to part 55, and has assigned OMB 
control number 2060-0249.\3\ This action does not impose a new 
information burden under PRA because this action only updates the state 
rules that are incorporated by reference into 40 CFR part 55, appendix 
A.
