I. The State's Submittal

A. What rule did the State submit?

    Table 1 lists the rule addressed by this proposal with the dates 
that it was amended by the ICAPCD and submitted by the California Air 
Resources Board (CARB), which is the governor's designee for California 
SIP submittals.

                                             Table 1--Submitted Rule
----------------------------------------------------------------------------------------------------------------
           Local agency                 Rule No.             Rule title             Amended         Submitted
----------------------------------------------------------------------------------------------------------------
ICAPCD............................             207   New and Modified                  9/11/18          10/5/18
                                                      Stationary Source Review.
----------------------------------------------------------------------------------------------------------------

    On February 22, 2019, the EPA determined that the submittal for 
ICAPCD Rule 207 met the completeness criteria in 40 CFR part 51 
Appendix V, which must be met before formal EPA review.

B. Are there other versions of this rule?

    On September 5, 2017, the EPA finalized a conditional approval of 
Rule 207, as amended October 22, 2013, into the California SIP. 82 FR 
41895.

C. What is the purpose of the submitted rule?

    Section 110(a) of the CAA requires states to submit regulations 
that include a pre-construction permit program for certain new or 
modified stationary sources of pollutants, including a permit program 
as required by Part D of Title I of the CAA.
    The purpose of District Rule 207 is to implement a federal 
preconstruction permit program for new and modified minor sources of 
regulated NSR pollutants, and new and modified major sources of 
regulated NSR pollutants for which the area is designated 
nonattainment. Imperial County is currently designated as a marginal 
nonattainment area for the 2015 8-hr ozone National Ambient Air Quality 
Standard (NAAQS) and a moderate nonattainment area for the 2008 ozone 
NAAQS. Portions of the county are designated as a serious nonattainment 
area for the 1987 24-hr PM10 NAAQS, as a moderate 
nonattainment area for the 2006 24-hr PM2.5 NAAQS, and as a 
moderate nonattainment area for the 2012 annual PM2.5 NAAQS. 
40 CFR 81.305. In addition, Imperial County was designated 
nonattainment for two revoked NAAQS: the 1979 1-hour ozone (moderate) 
and 1997 8-hour ozone (moderate) NAAQS.
    The rule revision corrects a deficiency for which the EPA 
previously finalized a conditional approval. 82 FR 41895. In that 
action, we explained our finding that the rule did not fully satisfy 40 
CFR 51.165(a)(13)'s requirements for regulation of PM2.5 
precursors as they pertain to ammonia. Our conditional approval of Rule 
217 was based on a commitment by CARB and the ICAPCD to submit a 
revised Rule 207 that includes ammonia as a PM2.5 precursor 
within twelve months of the effective date of our action (i.e., by 
October 5, 2018). To fulfill the commitment, the ICAPCD amended Rule 
207 on September 11, 2018 and the California Air Resources Board (CARB) 
submitted revised Rule 207 to the EPA on October 5, 2018.
    We present our evaluation of revised Rule 207, as identified in 
Table 1, in general terms below. Our technical support document (TSD), 
which is available in the docket for the proposed rulemaking, contains 
a more detailed analysis for today's proposed action.

II. The EPA's Evaluation and Action

A. How is the EPA evaluating the rule?

    The submitted rule must meet the CAA's general requirements for 
SIPs and SIP revisions in CAA sections 110(a)(2), 110(l), and 193 as 
well as the applicable requirements contained in part D of title I of 
the Act (sections 172 and 173) for a nonattainment NSR permit program. 
In addition, the submitted rule must contain the applicable regulatory 
provisions of 40 CFR 51.160-51.165 and 40 CFR 51.307.
    Among other things, section 110 of the Act requires that SIP rules 
be enforceable and provides that the EPA may not approve a SIP revision 
if it would interfere with any applicable requirements concerning 
attainment and reasonable further progress or any other requirement of 
the CAA. In addition, section 110(a)(2) and section 110(l) of the Act 
require that each SIP or revision to a SIP submitted by a state must be 
adopted after reasonable notice and public hearing.
    Section 110(a)(2)(c) of the Act requires each SIP to include a 
permit program to regulate the modification and construction of any 
stationary source within the areas covered by the SIP as necessary to 
assure attainment and maintenance of the NAAQS. The EPA's regulations 
at 40 CFR 51.160-51.164 provide general programmatic requirements to 
implement this statutory mandate commonly referred to as the ``minor 
NSR'' or ``general NSR'' permit program. These NSR program regulations 
impose requirements for SIP approval of state and local programs that 
are more general in nature as compared to the specific statutory and 
regulatory requirements for nonattainment NSR permitting programs under 
Part D of title I of the Act.
    Part D of title I of the Act contains the general requirements for 
areas designated nonattainment for a NAAQS (section 172), including 
preconstruction permit requirements for new major sources and major 
modifications proposing to construct in nonattainment areas (section 
173).

[[Page 10755]]

    Additionally, 40 CFR 51.165 sets forth the EPA's regulatory 
requirements for SIP-approval of a nonattainment NSR permit program.
    The protection of visibility requirements that apply to New Source 
Review programs are contained in 40 CFR 51.307. This provision requires 
that certain actions be taken in consultation with the local Federal 
Land Manager if a new major source or major modification may have an 
impact on visibility in any mandatory Class I Federal Area.
    Section 110(l) of the Act prohibits the EPA from approving any SIP 
revisions that would interfere with any applicable requirement 
concerning attainment and reasonable further progress (RFP) or any 
other applicable requirement of the CAA. Section 193 of the Act, which 
only applies in nonattainment areas, prohibits the modification of a 
SIP-approved control requirement in effect before November 15, 1990, in 
any manner unless the modification insures equivalent or greater 
emission reductions of such air pollutant.
    The EPA has reviewed the submitted rule in accordance with the rule 
evaluation criteria described above. With respect to procedures, based 
on our review of the public process documentation included in the 
October 5, 2018 submittal, we are proposing to approve the submitted 
rule in part because we have determined that the ICAPCD has provided 
sufficient evidence of public notice and opportunity for comment and 
public hearings prior to adoption and submittal of this rule, in 
accordance with the requirements of CAA sections 110(a)(2) and 110(l). 
The amendment of Rule 207 now also includes ammonia as a potential 
precursor to PM2.5, thus resolving the conditional approval 
issue from the September 2017 action. Specifically, the revised Rule 
207 updated definitions of ``emission increase'', ``major stationary 
source'', ``precursors'', and ``significant'' to be consistent with 
local and federal regulations and added language to specify when best 
available control technology requirements apply to ammonia emissions. 
Our TSD, which can be found in the docket for this rule, contains a 
more detailed discussion of the approval criteria.

B. Public Comment and Proposed Action

    As authorized in section 110(k)(3) of the Act, the EPA proposes to 
fully approve the submitted rule because it fulfills all relevant 
requirements. We will accept comments from the public on this proposal 
until April 22, 2019. If we take final action to approve the submitted 
rule, our final action will incorporate this rule into the federally-
enforceable SIP.

III. Incorporation by Reference

    In this rule, the EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by 
reference the ICAPCD rule described in Table 1 of this preamble. The 
EPA has made, and will continue to make, these materials available 
through www.regulations.gov and at the EPA Region IX Office (please 
contact the person identified in the FOR FURTHER INFORMATION CONTACT 
section of this preamble for more information).

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
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 Clean Air Act; 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 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 May 21, 2019. 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).)
