Federal Register / Vol. 87, No. 16 / Tuesday, January 25, 2022 / Rules and Regulations 3663 

1Hereinafter, the terms ‘‘North Carolina SIP’’ and 

‘‘SIP’’ refer to the North Carolina regulatory portion 

of the North Carolina SIP (i.e., the portion that 

contains SIP-approved North Carolina regulations). 2The Mecklenburg County, North Carolina 

revision that is dated April 24, 2020, and received 

by EPA on June 19, 2020, is comprised of three 

previous submittals—one dated January 21, 2016; 

one dated October 25, 2017; and one dated January 

14, 2019. 

3Additionally, EPA notes that NCDAQ did not 

request EPA approval into the LIP of several Section 

2.2600 rules, including: Rules 2.2616, Fluorides; 

2.2618, Mercury; 2.2619, Arsenic, Beryllium, 

Cadmium, Hexavalent Chromium; and 2.2620, 

Dioxins and Furans. Provisions for these pollutants 

were not previously included in the Mecklenburg 

LIP. 

4Except for the addition of paragraph 2.0501(e), 

with an effective date of June 1, 2008; and except 

for changes to remove and recodify the prefatory 

text at 2.0501(c) and for subparagraphs (c)(3), (c)(4), 

(c)(5), (c)(6), (c)10, (c)(15), (c)(16), and (c)(18), 

which will remain unchanged with a state effective 

date of June 14, 1990. Because EPA is acting on 

other portions of Rule 2.0501, which includes 

moving former paragraph (e) to paragraph (c) with 

an effective date of June 1, 2008, there will be two 

paragraphs 2.0501(c), with different state effective 

dates. EPA will consider the remaining portions of 

the June 14, 1990 version of paragraph (c) in a 

separate action. 

5Except for paragraph 2.2602(i), which 

corresponds to existing 2.0501(c)(18) in the LIP.

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is finalizing approval of 

a State Implementation Plan (SIP) 

revision to the Mecklenburg County 

portion of the North Carolina SIP, 

hereinafter referred to as the 

Mecklenburg County Local 

Implementation Plan (LIP). The revision 

was submitted through the North 

Carolina Division of Air Quality 

(NCDAQ), on behalf of Mecklenburg 

County Air Pollution Control (MCAQ), 

via a letter dated April 24, 2020, which 

was received by EPA on June 19, 2020. 

This SIP revision includes changes to 

Mecklenburg County Air Pollution 

Control Ordinance (MCAPCO) rules 

incorporated into the LIP regarding 

performance testing for stationary 

sources of air pollution. EPA is 

approving these changes pursuant to the 

Clean Air Act (CAA or Act). 

DATES: This rule is effective February 

24, 2022.

SUPPLEMENTARY INFORMATION: 

I. Background and Overview 

The Mecklenburg LIP was submitted 

to EPA on June 14, 1990, and EPA 

approved the plan on May 2, 1991. See 

56 FR 20140. Mecklenburg County is 

now requesting that EPA approve 

changes to the LIP for, among other 

things, general consistency with the 

North Carolina SIP.1 Mecklenburg 

County prepared three submittals in 

order to update the LIP and reflect 

regulatory and administrative changes 

that NCDAQ made to the North Carolina 

SIP since EPA’s 1991 LIP approval.2 The 

three submittals were submitted as 

follows: NCDAQ transmitted the 

October 25, 2017, submittal to EPA but 

later withdrew it from review through a 

letter dated February 15, 2019. On April 

24, 2020, NCDAQ resubmitted the 

October 25, 2017, update to EPA and 

also submitted the January 21, 2016, and 

January 14, 2019, updates. Due to an 

inconsistency with public notices at the 

local level, these submittals were 

withdrawn from EPA through the letter 

dated February 15, 2019. Mecklenburg 

County corrected this error, and NCDAQ 

submitted the updates to EPA in a 

submittal dated April 24, 2020. 

This final rule modifies the LIP by 

revising, adding, and removing several 

rules related to the source testing rules, 

located in MCAPCO Article 2.0000, Air 

Pollution and Control Regulations and 

Procedures. The specific sections 

addressed in this final rule are Section 

2.2600, Source Testing, Section 2.0900, 

Volatile Organic Compounds, and Rule 

2.0501 of Section 2.0500, Compliance 

with Emission Control Standards.3 The 

April 24, 2020, LIP revision first makes 

minor changes to recodify portions of 

Rules 2.0501 of Section 2.0500 and 

several rules in Section 2.0900. Next, 

the LIP revision removes Rule 2.0941, 

Alternative Method for Leak Testing, 

from the SIP, which in effect removes an 

alternative test for vapor leaks in 

gasoline tank trucks which is no longer 

available in Mecklenburg County. In 

addition, other changes modify the LIP 

by updating or incorporating new 

performance testing requirements, and 

by making other minor changes to 

language throughout the recodified rules 

for consistency. See EPA’s November 

26, 2021, notice of proposed rulemaking 

(NPRM) for further detail on these 

changes and EPA’s rationale for 

approving them. See 86 FR 67412. EPA 

did not receive public comments on the 

November 26, 2021, NPRM. 

II. Incorporation by Reference

Volatile Organic Compound Testing 

Methods; Rule 2.2614, Determination of 

VOC Emission Control System 

Efficiency; and Rule 2.2615, 

Determination of Leak Tightness and 

Vapor Leaks. EPA is also incorporating 

by reference Rule 2.0901, Definitions, 

with an effective date of January 1, 

2009. Also in this document, EPA is 

finalizing the removal of the following 

Mecklenburg County rules from the 

Mecklenburg portion of the North 

Carolina State Implementation Plan, 

which are incorporated by reference in 

accordance with the requirements of 1 

CFR part 51: Rule 2.0913, Determination 

of Volatile Content of Surface Coatings; 

Rule 2.0914, Determination of VOC 

Emission Control System Efficiency; 

Rule 2.0915, Determination of Solvent 

Metal Cleaning VOC Emissions; Rule 

2.0916, Determination: VOC Emissions 

from Bulk Gasoline Terminals; Rule 

2.0939, Determination of Volatile 

Organic Compound Emissions; Rule 

2.0940, Determination of Leak Tightness 

and Vapor Leaks; Rule 2.0941, 

Alternative Method for Leak Tightness; 

and Rule 2.0942, Determination of 

Solvent in Filter Waste. EPA has made, 

and will continue to make the State 

Implementation Plan generally available 

at the EPA Region 4 Office (please 

contact the person identified in the FOR

FURTHER INFORMATION CONTACT section of 

this preamble for more information). 

Therefore, the revised materials as 

stated above, have been approved by 

EPA for inclusion in the SIP, 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.6

III. Final Action 

EPA is approving the April 24, 2020, 

SIP revision to revise, add, and remove 

several source testing rules from the LIP, 

as described above. EPA believes these 

changes are consistent with the CAA, 

and this revision will not impact the 

national ambient air quality standards 

or interfere with any other applicable 

requirement of the Act. 

IV. Statutory and Executive Order 

Reviews 

Under the CAA, the Administrator is 

required to approve a SIP submission 

that complies with the provisions of the 

Act and applicable Federal regulations. 

See 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. 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); 

• 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). 

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 as specified by Executive 

Order 13175 (65 FR 67249, November 9, 

2000), nor will it impose substantial 

direct 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 CAA, 

petitions for judicial review of this 

action must be filed in the United States 

Court of Appeals for the appropriate 

circuit by March 28, 2022. 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).

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is approving multiple 

state implementation plan (SIP) 

revisions submitted by the 

Commonwealth of Pennsylvania. These 

revisions were submitted by the 

Pennsylvania Department of 

Environmental Protection (PADEP) to 

establish and require reasonably

14 major volatile organic compound 

(VOC) and/or nitrogen oxide (NOX) 

emitting facilities pursuant to the 

Commonwealth of Pennsylvania’s 

conditionally approved RACT 

regulations. In this rule action, EPA is 

approving source-specific (also referred 

to as ‘‘case-by-case’’ or CbC) RACT 

determinations or alternative NOX

emissions limits for sources at 14 major 

NOX and VOC emitting facilities within 

the Commonwealth submitted by 

PADEP. These RACT evaluations were 

submitted to meet RACT requirements 

for the 1997 and 2008 8-hour ozone 

national ambient air quality standards 

(NAAQS). EPA is approving these 

revisions to the Pennsylvania SIP in 

accordance with the requirements of the 

Clean Air Act (CAA) and EPA’s 

implementing regulations. 

DATES: This final rule is effective on 

February 24, 2022.

SUPPLEMENTARY INFORMATION: 

I. Background 

On August 2, 2021, EPA published a 

notice of proposed rulemaking (NPRM). 

86 FR 41421. In the NPRM, EPA 

proposed approval of case-by-case 

RACT determinations or alternative 

NOX emissions limits for sources 14 

facilities, as EPA found that the RACT 

controls for these sources met the CAA 

RACT requirements for the 1997 and 

2008 8-hour ozone NAAQS. PADEP 

submitted the SIP revisions for sources 

at these facilities on May 7, 2020. 

Under certain circumstances, states 

are required to submit SIP revisions to 

address RACT requirements for both 

major sources of NOX and VOC and any 

source covered by control technique 

guidelines (CTG) for each ozone 

NAAQS. Which NOX and VOC sources 

in Pennsylvania are considered ‘‘major,’’ 

and are therefore subject to RACT, is 

dependent on the location of each 

source within the Commonwealth. 

Sources located in nonattainment areas 

would be subject to the ‘‘major source’’ 

definitions established under the CAA 

based on the area’s current 

classification(s). In Pennsylvania, 

sources located in any ozone 

nonattainment areas outside of 

moderate or above are subject to source 

thresholds of 50 tons per year (tpy) 

because of the Ozone Transport Region 

(OTR) requirements in CAA section 

184(b)(2). 

On May 16, 2016, PADEP submitted 

a SIP revision addressing RACT for both 

the 1997 and 2008 8-hour ozone 

NAAQS in Pennsylvania. PADEP’s May 

16, 2016 SIP revision intended to 

address certain outstanding non-CTG 

VOC RACT, VOC CTG RACT, and major 

source VOC and NOX RACT 

requirements for both standards. The 

SIP revision requested approval of 

Pennsylvania’s 25 Pa. Code 129.96–100,
