# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule.

# SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve portions of revisions to a State Implementation Plan (SIP) submitted by the State of North Carolina through the North Carolina Department of Environmental Quality, Division of Air Quality (DAQ), on September 18, 2009, and July 10, 2019. These SIP revisions seek to modify the State's rules that define the categories of facilities that are exempted from Title V permitting requirements by limiting their potential emissions (“exclusionary rules”) and the categories of facilities that are exempted from the State's rules that address the permitting requirements for non-Title V facilities (“permit exemption rules”). EPA is proposing to approve this revision pursuant to the Clean Air Act (CAA or Act).

# SUPPLEMENTARY INFORMATION:

## I. Background

### A. Submittal—September 18, 2009

                    On September 18, 2009, DAQ submitted revisions to 15A North Carolina Administrative Code (NCAC) Subchapter 02Q, Section .0902,                     *Temporary Crushers,*[1]                                          for review and approval into the SIP. These changes are part of North Carolina's permit exemption rules at Section .0900 that define the categories of facilities that are exempted from the State's regulations that address the permitting requirements for non-Title V facilities. These changes are discussed in more detail in Section II.                

### B. Submittal—July 10, 2019

                    On July 10, 2019, DAQ submitted SIP revisions to EPA with changes to the following rules in 15A NCAC 02Q Section .0800 that define the categories of facilities that are exempted from Title V permitting requirements by limiting their potential emissions: Section .0801,                     *Purpose and Scope;*                     Section .0802,                     *Gasoline Service Stations and Dispensing Facilities;*                     Section .0803,                     *Coating, Solvent Cleaning, Graphic Arts Operations;*                     Section .0804,                     *Dry Cleaning Facilities;*                     Section .0805,                     *Grain Elevators;*                     Section .0806,                     *Cotton Gins;*                     and Section .0807,                     *Emergency Generators;*                     and Section .0809,                     *Concrete Batch Plants.*[2]                                          The July 10, 2019, SIP revisions also contain changes to the following permit exemption rules: Section .0901,                     *Purpose and Scope;*                     and Section .0902,                     *Temporary Crushers.*                     These changes are discussed in more detail in Section II.                

## II. Analysis of the State Submittals

                    The revisions that are the subject of this proposed rulemaking make changes to exclusionary rules and permit exemption rules under Subchapter 2Q [3]                                          of the North Carolina SIP. These changes revise the recordkeeping and reporting requirements of the exclusionary rules; remove Section .0809,                     *Concrete Batch Plants;*                     revise the provisions of Section .0902,                     *Temporary Crushers;*                     and revise language and reformat the regulatory citations contained in the exclusionary and permit exemption rules. Detailed descriptions of the changes are provided below.                

                    Section .0801,                     *Purpose and Scope,*                     is revised to modify language and reformat the regulatory citations of this section. In addition, the recordkeeping and reporting requirement exemptions are removed. New paragraphs have been created using the existing text of this section. The language changes in this section pertain to updates to subject-verb agreements and word tense. EPA is proposing to approve these changes to these rules because they are grammatical and organizational in                           ( print page 5092)                        nature and therefore do not interfere with any applicable requirement concerning attainment or any other applicable requirement of the Act.                

                    North Carolina submitted changes to several rules within Section .0800 which do not alter the meaning or make significant changes to those rules. Specifically, the following rules are submitted with changes to update a cross-reference to where the “responsible official” at a facility is defined in the North Carolina regulations, reformat regulatory citations, make minor language edits, and correct typographical errors, where applicable: Sections .0802,                     *Gasoline Service Stations and Dispensing Facilities;*                     [4]                                          .0803,                     *Coating, Solvent Cleaning,*[5] *Graphic Arts Operations;*.0804,                     *Dry Cleaning Facilities;*.0805,                     *Grain Elevators;*.0806,                     *Cotton Gins;*.0807,                     *Emergency Generators;*                     and Section .0901,                     *Purpose and Scope.*                     EPA is proposing to approve these changes to these rules because they do not alter the meaning of the regulations. . . .                

                    DAQ has repealed Section .0809,                     *Concrete Batch Plans*                     and is proposing to remove it from the SIP. This rule covered certain sizes of concrete batch plants that use fabric filters or equivalently effective control devices to control particulate emissions to limit production such that the potential to emit (PTE) would remain below applicable Title V thresholds as determined by the State. Under the rule, these facilities were not required to obtain major source operating permits pursuant to 02Q .0500,                     *Title V Procedures.*                     Section .0809 functioned as a flexible permitting mechanism to cover certain types of concrete batch plants that wished to avoid Title V permitting. Sources previously covered by this rule can elect to obtain synthetic minor operating permits pursuant to 02Q .0315,                     *Synthetic Minor Facilities,*                     or otherwise have the option to obtain a Title V permit pursuant to 02Q .0500 if their PTE is above the Title V thresholds. EPA has preliminarily determined that repealing Section .0809 does not interfere with any applicable requirement concerning attainment or any other applicable requirement of the Act because it simply removes a mechanism sources could use to avoid Title V permitting. Accordingly, EPA is proposing to remove Section .0809 from the SIP.                

                    Section .0902,                     *Temporary Crushers,*                     is revised with edits from the September 18, 2009,[6]                                          and July 10, 2019, submittals that include clarifying edits, changes to formatting, minor modifications to language, correction of typographical errors, and renumbering.[7]                                          First, the permit exemption regarding temporary crushers is revised to remove language related to the diesel fuel burning equipment at these facilities. Previously, to qualify for the exemption from 02Q .0300,                     *Construction and Operating Permits,*                     temporary crushers that used a diesel-fired generator or diesel engine to drive the crusher could not burn more than 17,000 gallons of diesel at the facility. North Carolina explains that removing this language is necessary because DAQ does not regulate engines such as these, which are subject to Title II of the CAA,                     *Emissions Standards for Moving Sources.*                     Any associated engines at such temporary sources would be defined as portable and, as such, not considered part of a stationary source. Therefore, the effect of removing these engines from the rule exempting temporary crushers is clarifying in nature and does not alter existing permitting requirements. The edits also add a new paragraph (i), which requires an owner or operator of a crusher to apply for and receive an air quality permit before beginning operations (should they plan to operate for more than twelve months). Other revisions include updated cross-references to applicable rules and updated recordkeeping and reporting requirements to reflect the removal of these engines from the exemption. Remaining edits include updates to numbering, minor changes to existing language, and correction of typographical errors. EPA is proposing to approve these minor and clarifying changes to Section .0902 because they do not interfere with any applicable requirement concerning attainment or any other applicable requirement of the Act.                

## III. Incorporation by Reference

                    In this notice, 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, EPA is proposing to incorporate by reference the following sections of 15A NCAC Subchapter 02Q with a state-effective date of April 1, 2018: Section .0801,                     *Purpose and Scope;*                     Section .0802,                     *Gasoline Service Stations and Dispensing Facilities;*                     Section .0803,                     *Coating, Solvent Cleaning, Graphic Arts Operations;*                     Section .0804,                     *Dry Cleaning Facilities;*                     Section .0805,                     *Grain Elevators;*                     Section .0806,                     *Cotton Gins;*                     Section .0807,                     *Emergency Generators;*                     Section .0901,                     *Purpose and Scope*                     and Section .0902,                     *Temporary Crushers*                     (with the exception of .0902(d)). EPA is also proposing to remove North Carolina regulation 15A NCAC Subchapter 02Q Section .0809,                     *Concrete Batch Plants,*                     from the North Carolina SIP, which is incorporated by reference in accordance with the requirements of 1 CFR part 51. These changes are proposed to revise the recordkeeping and reporting requirements of the permitting exclusionary rules, remove the “Concrete Batch Plants” regulation, revise language, and reformat the regulatory citations contained in these regulations. EPA has made, and will continue to make, these materials generally available through                     *www.regulations.gov*                     and at the EPA Region 4 office (please contact the person identified in the                     **For Further Information Contact**                    section of this preamble for more information).                

## IV. Proposed Action

                    EPA is proposing to approve the changes described above to the North Carolina SIP submitted by the State of North Carolina on September 18, 2009, and July 10, 2019. The changes under Subchapter 02Q Section .0801,                     *Purpose and Scope;*                     Section .0802,                     *Gasoline Service Stations and Dispensing                               ( print page 5093)                            Facilities;*                     Section .0803,                     *Coating, Solvent Cleaning, Graphic Arts Operations;*                     Section .0804,                     *Dry Cleaning Facilities;*                     Section .0805,                     *Grain Elevators;*                     Section .0806,                     *Cotton Gins;*                     Section .0807,                     *Emergency Generators;*                     Section .0901,                     *Purpose and Scope;*                     and                     *Section*.0902,                     *Temporary Crushers,*                     are proposed to revise the recordkeeping and reporting requirements of the permitting exclusionary rules, remove Section .0809, the                     *Concrete Batch Plants*                     regulation, revise language, and reformat the regulatory citations contained in these regulations. The proposed changes are consistent with the CAA.                

## 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 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 proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed 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).

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.
