[EPA-R08-OAR-2012-0761; FRL-9907-11-Region-8]

Approval and Promulgation of State Implementation Plan Revisions; 
Revisions to the Air Pollution Control Rules; North Dakota

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve State Implementation Plan (SIP) revisions submitted by the 
Governor of North Dakota on April 14, 2011. The revisions affect North 
Dakota's air pollution control rules regarding general provisions, 
ambient air quality standards (sulfur dioxide (SO2), 
nitrogen dioxide (NOX), and lead), and permitting. EPA acted 
separately on other provisions in the April 14, 2011 submittal related 
to North Dakota's regulation of greenhouse gases (GHGs) under its 
Prevention of Significant Deterioration (PSD) program. This action is 
being taken under section 110 of the Clean Air Act.

DATES: Written comments must be received on or before March 27, 2014.

II. Background

    The Act requires states to follow certain procedures in developing 
implementation plans and plan revisions for submission to EPA. Sections 
110(a)(2) and 110(l) of the Act provide that each implementation plan 
must be adopted after reasonable notice and public hearing.
    To provide for public comment, the North Dakota Department of 
Health (NDDH), after providing notice, held a public hearing on August 
19, 2010 to consider the revisions to its Air Pollution Control Rules. 
Following the public hearing, comment period, and legal review by the 
North Dakota Attorney General's Office, NDDH adopted the revisions. The 
revisions to the Air Pollution Control Rules became effective on April 
1, 2011. The North Dakota Governor submitted the SIP revisions to us 
with a letter dated April 14, 2011.

III. Analysis of SIP Revisions

    We are proposing action on the April 14, 2011 submittal for SIP 
revisions that involve the following chapters of the North Dakota 
Administrative Code (NDAC): 33-15-01, ``General Provisions;'' 33-15-02, 
``Ambient Air Quality Standards;'' and 33-15-14, ``Designated Air 
Contaminant Sources, Permit to Construct, Minor Source Permit to 
Operate, Title V permit to Operate.'' We previously acted on the 
revisions to NDAC 33-15-15, ``Prevention of Significant Deterioration 
of Air Quality'' in the April 14, 2011 submittal regarding regulation 
of GHGs and fine particulate matter (PM2.5) under North 
Dakota's PSD program in 2012 (77 FR 64734, October 23, 2012). The 
following is our description and analysis of the revisions in this 
proposed action which the State submitted to us for approval.

A. Chapter 33-15-01, NDAC, General Provisions

    The State revised section 33-15-01-04.52 and cross-referenced and 
incorporated by reference the version of 40 CFR 51.100(s) as it existed 
on July 2, 2010 for purposes of defining ``volatile organic compounds'' 
(the prior date used was March 1, 2008). This change is minor and is 
consistent with relevant CAA and regulatory requirements.

B. Chapter 33-15-02, NDAC, Ambient Air Quality Standards

    In section 33-15-02-04.1, ``Particulates and Gases,'' the State 
deleted the language, ``Except as provided in section 33-15-02-07 . . 
.'' at EPA's request. We were concerned that the cross reference to 
subsection 33-15-02-07.4 in 33-15-02-07, ``Concentrations of Air 
Contaminants in the Ambient Air Restricted,'' gave discretion to the 
state director to exempt, from ambient air quality standards, emissions 
during malfunctions and maintenance shutdowns. We asked the State to 
address our concern. The deletion of subsection 33-15-02-07.4 from 33-
15-02-07 and the deletion of the language cross referencing to it in 
subsections 33-15-02-04.1, 33-15-02-07.1 and 33-15-02-07.2 addresses 
our concern and is consistent with CAA requirements.
    In section 33-15-02-07, ``Concentrations of Air Contaminants in the 
Ambient Air Restricted,'' the State deleted subsection 33-15-02-07.3 
and the cross references to this subsection in 33-15-02-07.1 and 33-15-
02-07.2. Prior to this revision, there was a 1-hour state ambient air 
quality standard (SAAQS) for SO2 of 273 parts per billion 
(ppb). There was no 1-hour SO2 national ambient air quality 
standard (NAAQS) at that time. Because there were both a 24-hour and 
annual SAAQS and NAAQS for SO2, coal conversion facilities 
and petroleum refineries were exempt from the SAAQS per North Dakota 
Century Code (NDCC) 23-25-03.2. North Dakota NDAC 33-15-02-07.3 
clarified that these source categories only had to meet the NAAQS. The 
State's rule revision eliminated the 1-hour SAAQS for SO2 
and adopted the 1-hour NAAQS (75 ppb). The revision makes the 
SO2 SAAQS and the NAAQS the same; NDAC 33-15-02-07.3 is thus 
unnecessary. This revision is consistent with CAA and regulatory 
requirements.
    Also in section 33-15-02-07, Tables 1 and 2 were revised. Table 1, 
``Ambient Air Quality Standards,'' that lists the State ambient air 
quality standards was revised to add the new 2010 federal 1-hour 
standards for NOX and SO2 and to amend the 
standard for lead to the 2008 federal standard. Table 2, ``National 
Ambient Air Quality Standards,'' includes the old federal standards for 
SO2. The State initially proposed that Table 2 be deleted 
and that the new federal SO2 standards be incorporated into 
Table 1. We asked the State to retain the old federal SO2 
standards for one year after designation of the new standard.\1\ The 
State addressed our concerns by retaining the old primary 
SO2 standards in Table 2, by adding the new primary 
SO2 standards to Table 1, and by moving the secondary 
SO2 standard from Table 2 to Table 1. The State added an 
explanation after Table 2 regarding the federal requirement to retain 
the standards for one year after designation. These revisions were made 
to reflect the federal standards and are consistent with CAA and 
regulatory requirements.
---------------------------------------------------------------------------

    \1\ Per revised 40 CFR 50.4, effective August 23, 2010 (75 FR 
35520, June 22, 2010), ``[t]he SO2 NAAQS set forth in 
this section will no longer apply to an area one year after the 
effective date of the designation of that area, pursuant to section 
107 of the Clean Air Act, for SO2 NAAQS set forth in 
Sec.  50.17 . . .''
---------------------------------------------------------------------------

C. Chapter 33-15-14, NDAC, Designated Air Contaminant Sources, Permit 
To Construct, Minor Source Permit To Operate, Title V Permit To Operate

    In Chapter 33-15-14, in addition to several housekeeping revisions, 
the State made revisions to sections 33-15-14-01 and 33-15-14-02 with 
the intent to change the permitting requirement for sources subject to 
a new source performance standard (NSPS) or national emission standard 
for

[[Page 10450]]

hazardous air pollutant (NESHAP). Previously, the SIP-approved minor 
source permit rule required any source subject to a NSPS or NESHAP to 
obtain a permit from the State regardless of the quantity of source 
emissions. The State has changed the rule so the permit requirement 
only applies to sources subject to a state-adopted NSPS or NESHAP. The 
State made this change to avoid the burden of permitting the numerous 
oil and gas facilities that became subject to the newly promulgated 
federal NSPS at 40 CFR part 60, subpart OOOO (Standards of Performance 
for Crude Oil and Natural Gas Production, Transmission and 
Distribution). The effect of these revisions is the State, by not 
adopting subpart OOOO into state law (and with no intention to adopt it 
in the future) will not have to permit the sources subject to subpart 
OOOO. Coupled with an existing exemption for oil and gas production 
operations at subsection 33-15-14-02.13.o and the State's oil and gas 
registration program at Chapter 33-15-20, the sources the State intends 
to exclude from permitting include the multitude of small units, such 
as tanks, engines, and other oil and gas production related units 
normally subject to the State's minor source New Source Review (NSR) 
program. State permitting requirements aside, national emissions 
standards in any NSPS or NESHAP including 40 CFR part 60, subpart OOOO 
still apply to the subject sources. The revisions related to NSPS and 
NESHAP permitting result in a relaxation of North Dakota's SIP since 
now a narrower subset of sources subject to NSPS and NESHAP 
requirements (only those sources subject to NSPS and NESHAP 
requirements that are adopted by the State) are subject to permitting. 
While the State has not indicated any intention to return delegation of 
any currently state-adopted NSPS or NESHAP requirements, EPA has 
considered this possibility. Regarding the potential impacts to any 
future relaxation related to such returned delegation, should this 
occur, EPA will continue to work closely with the State to review these 
requirements as well as the rest of its minor NSR program. Like other 
states, EPA has some concerns with the stringency of North Dakota's 
minor NSR program, and we acknowledge that there are ongoing 
discussions with North Dakota to clarify and strengthen the State's 
minor NSR program including addressing oil and gas production. North 
Dakota approached this current SIP revision in a prospective manner, 
revising its rules prior to EPA issuing the subpart OOOO requirements.
    CAA section 110(l) requires a demonstration that a SIP revision 
does not interfere with any requirement concerning attainment and that 
a relaxation is sufficiently protective of air quality and other CAA 
requirements in order for EPA to approve the relaxation. EPA conducted 
such a demonstration for the permitting rule revision in the April 2011 
submittal finding the revisions are not presently interfering with the 
State's SIP control strategy or causing NAAQS violations in North 
Dakota. Our demonstration is included in the docket for this action.
    The specific revisions related to the minor source NSPS and NESHAP 
permitting issue as well as other revisions to the minor source NSR 
program are described below.
    In section 33-15-14-01, ``Designated Air Contaminant Sources,'' the 
State revised the list of sources ``capable of causing or contributing 
to air pollution.'' The revised sections read as follows:

    33-15-14-01.9. Any source for which an applicable federal 
standard of performance (40 CFR 60) has been adopted in chapter 33-
15-12.
    33-15-14-01.10. Any source for which an applicable national 
emission standard for hazardous air pollutants (40 CFR 61) has been 
adopted in chapter 33-15-13.

    In section 33-15-14-02, ``Permit to construct,'' the State made the 
following revisions:

    In subsection 33-15-14-02.1, ``Permit to construct required,'' 
the State deleted the following language from the end of the first 
paragraph, ``This requirement shall also apply to any source for 
which a federal standard of performance has been promulgated prior 
to such filing of an application for a permit to construct. A list 
of sources for which a federal standard has been promulgated, and 
the standards which apply to such sources, must be available at the 
department's offices.'' The subsection now reads, ``No construction, 
installation or establishment of a new stationary source within a 
source category designated in section 33-15-14-01 may be commenced 
unless the owner or operator thereof shall file an application for, 
and receive, a permit to construct in accordance with this 
chapter.''
    In subsection 33-15-14-02.13, ``Exemptions,'' the State deleted 
the following language from the end of the introductory sentence, 
``and there is no applicable new source performance standard, or 
national emission standard for hazardous air pollutants.'' This 
subsection now reads, ``A permit to construct is not required for 
the following stationary sources provided there is no federal 
requirement for a permit or approval for construction or 
operation.''
    In subsection 33-15-14-02.13.o, the State made a revision 
deleting an unnecessary subsection reference for the definition of 
major source which we are approving. The subsection now reads, ``Oil 
and gas production facilities as defined in chapter 33-15-20 which 
are not a major source as defined in section 33-15-14-06.'' The 
State is moving towards less precise numbering references, in some 
cases, to simplify any future rule renumbering requirements. In 
addition, under this provision, oil and gas production facilities 
that are not major sources are exempted from review and permitting. 
While EPA approved this provision in 1995, we do have concerns now 
that the provision may need to be strengthened in order to conform 
with the CAA and EPA's minor NSR regulations 40 CFR 51.150-51.164. 
EPA has not reviewed the substance of this rule as part of this 
action. The EPA is now merely approving the deletion of the 
numbering cross reference submitted by the State. The current 
version of the NDAC rule does not contain substantive changes from 
the prior codification that we approved into the SIP. EPA 
acknowledges that there are ongoing discussions with North Dakota to 
address EPA's concerns with the rule language that EPA previously 
approved into the North Dakota SIP. In a December 10, 2013 letter 
from Terry O'Clair, Director of North Dakota's Division of Air 
Quality to Gail Fallon, EPA Region 8, North Dakota committed to 
provide clarification of the applicability of the oil and gas 
production operations registration program and guidance. Because 
this rule revision in the SIP only deletes a numbering cross 
reference, we are proposing to approve this revision

    Also in Chapter 33-15-14, the State made several housekeeping 
revisions. A revision in subsection 1.12 is clarifying in nature and 
replaced language about a source's emissions ``affecting'' state air 
quality with language regarding a source that the State determined to 
``cause or contribute to a violation'' of air quality standards. A 
revision in subsection 1.15 added the word ``stationary'' to clarify 
the State's intent to regulate only stationary sources under its 
permitting program.\2\ The revised subsections read as follows:
---------------------------------------------------------------------------

    \2\ We acted previously on other revisions in the April 14, 2011 
submittal, pertaining to the State's regulation of greenhouse gases. 
Federal greenhouse gas requirements deal largely with mobile 
sources. See our 2012 action, 77 FR 64734, October 23, 2012, for a 
more detailed explanation.

    33-15-14-01.12. Any source which is determined by the department 
to cause or contribute to a violation of any SAAQS or violates the 
other provisions of chapter 33-15-02.
    33-15-14-01.15. Other stationary sources subject to a standard 
or requirement under the Federal Clean Air Act as amended.

    In section 33-15-14-03, ``Minor source permit to operate,'' the 
State deleted exception language in subsection 33-15-14-03.1.c related 
to the requirement for a minor source

[[Page 10451]]

permit to operate when a source is transitioning to a title V permit to 
operate as well as language for fees related to such sources that meet 
the title V applicability requirements. The subsection now reads, 
``Sources that are subject to the title V permitting requirements of 
section 33-15-14-06 are exempt from the requirements of this section.'' 
While the time frame related to the State issuing initial title V 
permits has largely passed, in the event a minor source's emissions 
grow to the extent that a title V permit becomes necessary, any 
applicable requirements in the minor source permit to operate will 
transition into the title V permit to operate. In such a case, until a 
title V permit is issued, the minor source permit remains in effect.
    The changes in Chapter 33-15-14 only affect the applicability of 
certain permitting requirements contained in this Chapter. These 
changes do not affect emission limits in the SIP or other requirements 
that would affect ambient concentrations of criteria pollutants. These 
changes are consistent with CAA and regulatory requirements.

IV. Proposed Action

    EPA is proposing to approve revisions to the North Dakota SIP that 
the Governor of North Dakota submitted with a letter dated April 14, 
2011 and that were state-effective April 1, 2011. Specifically, EPA is 
proposing to approve North Dakota's revisions to the following portions 
of the North Dakota Administrative Code: Chapter 33-15-01, ``General 
Provisions,'' section 33-15-01-04.52 ; Chapter 33-15-02, ``Ambient Air 
Quality Standards,'' sections 33-15-02-04.1, 33-15-02-07.1, 33-15-02-
07.2, 33-15-02-07.3, 33-15-02-07.4, section 33-15-02, Tables 1 and 2. 
EPA is proposing to approve Chapter 33-15-14, ``Designated Air 
Contaminant Sources, Permit to Construct, Minor Source Permit to 
Operate, Title V Permit to Operate,'' sections 33-15-14-01.9, 33-15-14-
01.10, 33-15-14-01.12, 33-15-14-01.15, 33-15-14-02.1, 33-15-14-02.13, 
33-15-14-02.13.o, 33-15-14-03.1c with the understanding that the State 
and EPA will continue discussions to clarify and strengthen the State's 
current minor source program as it relates to oil and gas production 
facilities. See section III of this action for a description of these 
revisions. EPA acted previously on the revisions to Chapter 33-15-15, 
``Prevention of Significant Deterioration of Air Quality,'' that were 
also included in the April 14, 2011 submittal. See 77 FR 64734, October 
23, 2012.

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 (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 
proposed action merely approves state law as meeting federal 
requirements; this proposed action 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 Order 
12866 (58 FR 51735, October 4, 1993);
     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.
