Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Infrastructure Requirements for the 2015 Ozone National 
Ambient Air Quality Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving a state 
implementation plan (SIP) revision submitted by the State of Maryland 
for the 2015 ozone national ambient air quality standard (NAAQS or 
standard). Whenever EPA promulgates a new or revised NAAQS, states are 
required to make a SIP submission showing how the existing approved SIP 
has all the provisions necessary to meet certain SIP requirements for 
the new or revised NAAQS, or to add any needed provisions necessary to 
meet these requirements. The SIP revision is required to address basic 
program elements, including, but not limited to, regulatory structure, 
monitoring, modeling, legal authority, and adequate resources necessary 
to assure attainment and maintenance of the standards. These elements 
are referred to as infrastructure requirements. Maryland has made a 
submittal addressing the infrastructure requirements for the 2015 ozone 
NAAQS. EPA is approving Maryland's SIP revision addressing the 
infrastructure requirements for the 2015 ozone NAAQS in accordance with 
the requirements of section 110(a) of the Clean Air Act (CAA).

DATES: This final rule is effective on October 18, 2019.

SUPPLEMENTARY INFORMATION: 

I. Background

    On October 26, 2015, EPA issued a final rule revising both the 
primary and secondary NAAQS for ozone to 0.070 parts per million (ppm) 
based on 8-hour average concentrations. Pursuant to section 110(a)(1) 
of the CAA, states are required to make SIP submissions to meet the 
applicable requirements of section 110(a)(2) within three years after 
EPA promulgates a new or revised NAAQS, or within a shorter period as 
EPA may prescribe. Section 110(a)(2) requires states to address basic 
SIP elements such as requirements for monitoring, basic program 
requirements and legal authority that are designed to assure 
implementation, maintenance, and enforcement of the new or revised 
NAAQS. EPA refers to this type of SIP submission as an ``infrastructure 
SIP submission'' because it focuses on the basic requirements that a 
state must have to provide for implementation, maintenance, and 
enforcement of the NAAQS at issue in the submission.

II. Summary of SIP Revision and EPA Analysis

    On October 11, 2018, EPA received from the State of Maryland, 
through the Maryland Department of the Environment (MDE), a formal SIP 
submission (#18-06) to satisfy the requirements of section 110(a) of 
the CAA for the 2015 ozone NAAQS. EPA reviewed Maryland's submittal 
and, subsequently on April 24, 2019, published a notice of proposed 
rulemaking (NPRM) regarding this submittal. See 84 FR 17125. The SIP 
submission addressed the following infrastructure elements, or portions 
thereof, for the 2015 ozone NAAQS: CAA section 110(a)(2)(A), (B), (C), 
(D)(i)(II), D(ii), (E), (F), (G), (H), (J), (K), (L), and (M).
    The rationale supporting EPA's proposed rulemaking action, 
including the scope of infrastructure SIP submissions in general, is 
explained in the published NPRM and the technical support document 
(TSD) and will not be restated here. The NPRM and TSD are available in 
the docket for this rulemaking at https://www.regulations.gov, Docket 
ID Number EPA-R03-OAR-2019-0036.

III. Public Comment and EPA's Response

    EPA received comments from one commenter in response to the April 
24, 2019 proposed approval of Maryland's 2015 ozone NAAQS 
infrastructure SIP. The commenter did not provide any personal 
information, such as a name or group affiliation, and therefore is 
considered anonymous. The commenter opposed EPA's proposed approval of 
the SIP submission on several grounds. The full text of the comment is 
in the docket for this rulemaking action.
    Comment 1: The commenter claims that EPA was incorrect in proposing 
to find that Maryland's 2015 ozone NAAQS infrastructure SIP submittal 
met the requirements of section 110(a)(2)(A) of the CAA, because 
Maryland is not attaining the 2015 ozone NAAQS of 70 parts per billion 
(ppb).\1\ The commenter cites and includes data from MDE's website 
showing 16 days when monitor data showed exceedances of the NAAQS in 
2018, and notes that the number of exceedances increased from 11 in 
2014.
---------------------------------------------------------------------------

    \1\ 70 ppb converts to 0.070 ppm.
---------------------------------------------------------------------------

    EPA Response: EPA disagrees with the commenter regarding the 
approvability of Maryland's infrastructure SIP submittal with respect 
to the requirements of CAA section 110(a)(2)(A) for the 2015 ozone 
NAAQS. First, in this action, EPA is evaluating the State's 
infrastructure SIP submission. In this context, EPA is not determining 
whether or not Maryland has met all of the potential emissions control 
requirements that may or may not ultimately be necessary in order to 
comply with CAA section 110(a)(2)(I), and part D, subpart 2 SIP 
requirements for nonattainment areas. In the context of evaluating an 
infrastructure SIP submission, EPA interprets section 110(a)(2)(A) of 
the CAA at this early stage of planning for a new or revised NAAQS only 
to require a state to identify the existing control measures already in 
the existing SIP that provide for implementation, maintenance, and 
enforcement of the 2015 ozone NAAQS. Section 110(a)(2) requires that 
each SIP ``include enforceable emission limitations and other control 
measures, means, or techniques . . . as well as schedules and 
timetables for compliance, as may be necessary or appropriate to meet 
the applicable requirements of [the CAA],'' which in this case is the 
2015 ozone standard. In later phases of SIP planning, in particular to 
meet requirements for nonattainment plan SIP submissions in designated 
nonattainment areas, states are required to adopt additional measures 
to provide for attainment of the NAAQS, as applicable. EPA has provided 
guidance explaining that nonattainment plan SIP submission requirements 
are separate from infrastructure SIP submission requirements.\2\
---------------------------------------------------------------------------

    \2\ See, Memorandum dated September 13, 2013, entitled 
``Guidance on Infrastructure State Implementation Plan (SIP) 
Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2),'' 
from Stephen D. Page, Director, Office of Air Quality Planning and 
Standards, to Regional Air Directors, Regions 1--10. A copy of this 
guidance is in the docket for this action.
---------------------------------------------------------------------------

    Second, to the extent that Maryland needs to adopt and submit any 
additional emission controls in nonattainment areas in order to attain 
the 2015 ozone NAAQS, the State will need to do so in a different type 
of SIP submission that it must submit later. EPA reviews an 
infrastructure SIP submittal to verify that the state's SIP provides 
for the implementation, maintenance, and enforcement of the NAAQS and 
that any additional requirements for a new NAAQS is met, but not to 
evaluate whether the state has met any potential nonattainment area 
plan requirements that apply separately and later. Under subpart 2 of 
part D of title I of the CAA, state planning and emissions control 
requirements in a nonattainment area for ozone are determined, in part, 
by the area's classification. Under subpart 2, EPA initially classified 
ozone nonattainment areas based on the severity of their ozone levels, 
as determined by the area's design value relative to the lower and 
upper design value thresholds for each classification. Nonattainment 
areas with a lower classification, such as ``marginal,'' have ozone 
levels at the time of designation that are closer to the standard than 
areas with a higher classification. Ozone nonattainment areas in the 
lower classification levels have fewer initial mandatory air quality 
planning and control requirements than those in higher classifications. 
EPA designated several areas within Maryland as marginal nonattainment 
areas for the 2015 ozone NAAQS. 83 FR 25776, 25812 (June 4, 2018); 40 
CFR 81.321. Section 182 of the CAA requires states with ozone 
nonattainment areas to submit various SIP elements within specified 
time frames. States with areas designated as marginal nonattainment 
have two years from the effective date of designation to submit SIP 
revisions addressing emissions inventories (required by CAA section 
182(a)(1)), reasonably available control technology (CAA section 
182(b)(2)) and certain emissions statement regulations.\3\ Maryland's 
effective date for the initial nonattainment designation for the 2015 
ozone NAAQS was August 3, 2018, so

[[Page 49064]]

the nonattainment SIP elements for Maryland for the 2015 ozone NAAQS 
are not due until August 3, 2020. CAA section 181 provides an 
increasing amount of maximum time from the date of designation to 
attain the standards for the progressively higher classifications: 
Marginal--3 years, moderate--6 years, serious--9 years, severe--15 or 
17 years, and extreme--20 years. Under EPA's interpretation of section 
181 of the CAA, marginal nonattainment areas have up to three years 
after the effective date of the nonattainment designation to attain the 
2015 ozone NAAQS. 40 CFR 51.1302. Thus, Maryland's marginal 
nonattainment areas for the 2015 ozone NAAQS have until June 4, 2021 to 
come into attainment. EPA's review of Maryland's infrastructure SIP 
submittal indicated that the State has numerous SIP approved 
regulations in place to control and reduce emissions of the ozone 
precursors nitrogen oxides (NOX) and volatile organic 
compounds (VOCs).

Standards for Ozone: Nonattainment Area State Implementation Plan 
Requirements. 83 FR 62998 (December 6, 2018).
---------------------------------------------------------------------------

    Third, regarding the ambient ozone measurements referenced by the 
commenter, EPA agrees that some of these preliminary 8-hour 
concentrations exceed the 0.070 ppm numerical level of the 2015 ozone 
NAAQS. However, an individual 8-hour average measurement at an 
individual monitor is not indicative of whether the 2015 ozone NAAQS 
has been violated in an area. The standard is met at an air quality 
monitor when the 3-year average of the annual fourth-highest daily 
maximum 8-hour average ozone concentration is less than or equal to the 
2015 ozone NAAQS (0.070 ppm). 40 CFR 50.19(b). Thus, three full years 
of data for each monitor is required, and more specifically, it is the 
3-year average of the annual fourth-highest daily maximum 8-hour 
average ozone concentration that is needed to ascertain if a monitor is 
attaining or not. None of the numerical values cited by the commenter, 
by themselves, can be used to determine if the monitor or area is 
violating the NAAQS. The commenter referred several times to 
preliminary daily ozone values and seemed to infer that these daily 
values could be compared to the 2015 ozone standard. This is misleading 
as the 2015 ozone standard is not measured by a singular day's reading. 
Therefore, the daily monitor readings are not comparable. Finally, EPA 
disagrees with the commenter that the Agency stated in the proposed 
approval notice that Maryland is currently attaining the 2015 ozone 
NAAQS. However, as mentioned previously, the State has until 2021 to 
attain.
    Comment 2: The commenter questioned EPA's proposed finding that 
Maryland has the necessary funding and personnel to implement the SIP, 
as required by CAA section 110(a)(2)(E)(i), and EPA's proposed finding 
that the SIP required major stationary sources to pay adequate permit 
fees to cover the cost of reviewing and acting upon a permit 
application, and that it was adequate to cover the cost of ensuring the 
permits are followed, as required by CAA section 110(a)(2)(L). The 
commenter questioned whether EPA has a formula for making these 
determinations, or hired a qualified forensic accountant to comb 
through MDE's finances to determine the financial stability of MDE. The 
commenter questions EPA's methods for evaluating the adequacy of 
Maryland's staffing and budget levels.
    EPA Response: As stated in the proposed approval for this action, 
EPA's evaluation indicates that the State of Maryland has the staffing 
and funding resources to meet SIP obligations in accordance with 
section 110(a)(2)(E) of the CAA. Maryland's infrastructure SIP 
submission for the 2015 ozone NAAQS (SIP submittal) indicated that 
MDE's Air and Radiation Division has a budget of $19.5 million for 
fiscal year 2019, which is on par with its budgets in 2017 and 2018, 
and currently has 167 personnel in the Air and Radiation Division. SIP 
submittal, pp. 7-8. These budget and staff levels have been consistent 
over the past number of years and over these years Maryland has been 
able to meet its statutory commitments, including submitting the 
required air quality data, attainment plans, and monitoring network 
plans.
    In addition, the SIP submittal cited the state law allowing MDE to 
seek funding, as well as the various funding sources for its programs, 
including CAA section 103 and 105 grants, the Maryland Clean Air Fund, 
permit fees, fees from vehicle emission inspections, and funds received 
from the Maryland Department of Transportation to help fund 
transportation-related air pollution programs. SIP submittal, pp. 7-8. 
Maryland also has an EPA-approved fee program under CAA title V which 
is used to support title V program elements such as permitting, 
monitoring, testing, inspections, and enforcement. EPA conducts 
periodic title V fee and program audits in accordance with generally 
accepted government auditing standards. Maryland regulation COMAR 
26.11.02.19 provides fee schedules and other relevant fee information 
regarding title V permits and state permits to operate. Regarding 
Maryland's CAA section 105 funding, Maryland's use of the funds is 
evaluated through the evaluation process requirements of 40 CFR part 
35, subpart A, which call for the State and EPA to jointly evaluate and 
report progress and accomplishments under the work plan.\4\ Maryland 
also has various permit programs that are self-funded as they apply 
fees for permit applications. Most of these permit program fees can be 
adjusted if the State determines that the fee does not cover the 
reasonable costs of reviewing and acting upon the permit applications. 
Based on EPA's various reviews of these existing resources, EPA 
reasonably concluded that Maryland has adequate funding and personnel 
to implement its SIP.
---------------------------------------------------------------------------

    \4\ A programmatic joint evaluation review of Maryland's Air 
Pollution Control Section 105 Grant work plan was conducted most 
recently between MDE and EPA on April 17, 2019.
---------------------------------------------------------------------------

    Comment 3: The commenter asserts that EPA cannot find this 
infrastructure SIP meets CAA section 110(a)(2)(B) because EPA had to 
issue a Data Requirements Rule (DRR) for sulfur dioxide 
(SO2) because Maryland did not have enough SO2 
monitors to adequately measure SO2.
    EPA Response: EPA disagrees with the commenter's assertion that the 
SO2 Data Requirements Rule is proof that Maryland currently 
does not have an adequate monitoring network for SO2, and 
therefore cannot meet the section 110(a)(2)(B) requirements. EPA 
disagrees with the commenter for three reasons.
    First, in this action, EPA is evaluating the state's infrastructure 
SIP submission for the 2015 ozone NAAQS. Accordingly, for purposes of 
section 110(a)(2)(B), EPA is evaluating whether Maryland has SIP 
provisions that provide for things such as required air quality 
monitoring and submission of required data with respect to the ozone 
NAAQS, not the SO2 NAAQS. The scope of EPA's evaluation of 
section 110(a)(2)(B) is described in the agency's guidance for 
infrastructure SIP submissions.\5\

Standards for Ozone: Nonattainment Area State Implementation Plan 
Requirements. 83 FR 62998 (December 6, 2018).
---------------------------------------------------------------------------

    Second, EPA has determined that Maryland has met the requirements 
of section 110(a)(2)(B) for the 2015 ozone NAAQS. Section 110(a)(2)(B) 
of the CAA requires that each plan shall provide for the establishment 
and operation of appropriate devices, methods, systems, and procedures 
necessary to monitor, compile, and analyze data on ambient air quality, 
and upon request, make such data available to EPA. As part of its 
determination, EPA verified the scope and continuing validity of the 
State law authority cited in Maryland's October 11, 2018

[[Page 49065]]

infrastructure SIP submission. Additionally, Maryland has SIP approved 
regulations located under COMAR 26.11.04.02 specifying that methods of 
measuring ambient air quality levels shall be aligned with those 
specified in 40 CFR parts 50, 51, 53 and 58, as amended. In addition, 
the State has submitted, and EPA has approved, annual network 
monitoring plans that specifically address the monitoring network 
requirements for the ozone NAAQS throughout Maryland. Most recently, 
EPA approved the 2018 annual network monitoring plan and concluded that 
Maryland's network of monitors meets regulatory requirements and is 
consistent with applicable guidance.\6\
---------------------------------------------------------------------------

    \6\ A copy of EPA's approval letter is in the docket for this 
action.
---------------------------------------------------------------------------

    Finally, the commenter is also incorrect with respect to the 
current status of SO2 monitoring in Maryland. Although not 
relevant in the context of this action on an infrastructure SIP 
submission for the 2015 ozone NAAQS, EPA notes that the DRR cited by 
the commenter did not specifically find that Maryland lacked sufficient 
SO2 monitors to monitor adequately for purposes of the 
SO2 NAAQS. Instead, the DRR required that states identify to 
EPA by January 15, 2016, those sources of SO2 within their 
jurisdiction emitting more than 2,000 tons per year (tpy) of 
SO2, or other SO2 sources or clusters of 
SO2 sources warranting evaluation. The DRR then gave states 
three options for characterizing SO2 concentrations around 
these sources: (1) By installing and using SO2 monitors; (2) 
by modelling SO2 concentrations; or (3) by adopting 
SO2 limits for the source to keep it below the 2,000 tpy 
threshold. States were required to choose an option for each source by 
July 1, 2016. For installation of a new SO2 monitor(s), 
states were to include information about the new monitor in the annual 
network monitoring plan by July 1, 2016. Maryland's 2016 annual 
monitoring plan identified any new SO2 monitors to be 
installed, and EPA's approval of that plan confirmed that the placement 
of any new SO2 monitors was acceptable.\7\ More importantly, 
Maryland was not even required to install monitors if it chose to do 
SO2 modeling instead, so any perceived lack of 
SO2 monitors could be remedied by modeling. EPA has no 
information that Maryland is not at this time meeting its obligations 
under the DRR, even if that were relevant in the context of EPA's 
evaluation of the State's compliance with section 110(a)(2)(B) in the 
context of an infrastructure SIP submission for the 2015 ozone NAAQS, 
which it is not.
---------------------------------------------------------------------------

    \7\ MDE included its DRR monitoring information in an addendum 
to the State's 2016 annual monitoring network plan. Maryland's 2016 
annual monitoring network plan was approved by EPA on November 10, 
2016. For reference, a copy of MDE's DRR addendum to their 2016 
annual monitoring network plan can be located in the docket for this 
rulemaking action at https://www.regulations.gov, Docket ID Number 
EPA-R03-OAR-2019-0036.
---------------------------------------------------------------------------

III. Final Action

    EPA is approving Maryland's October 11, 2018 infrastructure SIP 
submission which addresses the basic program elements, or portions 
thereof, specified in sections 110(a)(2)(A), (B), (C), (D)(i)(II), 
(D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M) of the CAA, 
necessary to implement, maintain, and enforce the 2015 ozone NAAQS. 
This rulemaking does not address section 110(a)(2)(I), or the NNSR 
permitting program requirements of section 110(a)(2)(C), which pertain 
to the nonattainment planning requirements of part D of the CAA. States 
are required to make other SIP submissions to meet those nonattainment 
area requirements later, after completion of designations, and, if 
required, would be due to EPA by the dates statutorily prescribed in 
CAA part D, subpart 2. Because the CAA directs states to make SIP 
submissions to address nonattainment plan requirements on a separate 
schedule, EPA does not interpret the CAA to require states to address 
these requirements in the infrastructure SIP submission due three years 
after adoption of a new or revised NAAQS.
    Additionally, this rulemaking does not address CAA section 
110(a)(2)(D)(i)(I) (significant contribution to nonattainment or 
interference of maintenance through interstate transport of air 
emissions) for the 2015 ozone NAAQS because Maryland's infrastructure 
SIP submission did not include these elements. EPA will take later, 
separate action on these requirements once they have been submitted.

IV. Statutory and Executive Order Reviews

A. General Requirements

    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, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.

B. Submission to Congress and the Comptroller General

    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

[[Page 49066]]

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).

C. Petitions for Judicial Review

    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 November 18, 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 pertaining to Maryland's section 110(a)(2) 
infrastructure elements for the 2015 ozone NAAQS may not be challenged 
later in proceedings to enforce its requirements. (See section 
307(b)(2).)
