Reg. 19.405 Action on Application. ARd33-6
As approved by the Arkansas Pollution Control and Ecology Commission
February 26, 2016 effective March 14, 2016. Submitted to EPA March 24, 2017 (AR-46), 
Regulations.gov document EPA-R06-OAR-2019-0301-0006 [AR029.06] adobe page 898.
Approved by EPA August 23, 2019 (84 FR 44235) SIP effective September 23, 2019 (ARd33),
Regulations.gov docket EPA-R06-OAR-2019-0301 [AR029].

     (A) Technical Review
     The Department will review the application submitted under this chapter in order to 
ensure to their reasonable satisfaction that:
          (1) the stationary source will be constructed or modified to operate without
interfering with attainment or maintenance of a national ambient air quality standard;
          (2) the stationary source will be constructed or modified to operate without violating
any applicable regulation adopted by the EPA pursuant to §§ 111, 112, and 114 of
the Clean Air Act as amended;
          (3) the stationary source will be constructed or modified to operate without resulting
in a violation of any applicable provisions of this regulation;
          (4) the emission rate calculations are complete and accurate; and
          (5) if the facility wishes to measure and/or monitor operating parameters rather than
actual emissions, the application describes a process which will be used to ensure
that the calculations are translated into enforceable limits on operational
parameters rather than emissions.
     (B) Proposed Action
          (1) If the Department initially determines the requirements of Reg. 19.405(A) are
met, they shall prepare a draft permit which:
               (a) contains such conditions as are necessary to comply with this Regulation;
               (b) addresses all federally regulated air pollutant emissions and all federally
regulated air pollutant emitting equipment at the stationary source except
pollutants or equipment specifically exempt or as specifically provided
for in paragraph (c) below; and
               (c) establishes Best Available Control Technology (BACT) permitted
emission rates, emission limitations or other enforceable conditions for
GHG emissions pursuant to Chapter 9 of this Regulation, if applicable.
Draft permits for facilities not subject to a BACT determination in regard
to GHG emissions pursuant to the provisions at Chapter 9 of this
Regulation shall not contain permitted emission rates, emission limitations
or other enforceable conditions related to GHG emissions. However, the
applicant may request that the Department include permitted emission
rates, emission limitations or other enforceable conditions related to GHG
emissions in the draft permit in order to set enforceable limits for the
purpose of establishing synthetic minor status. In the event any provision
of Regulation 19 is found to be in conflict with this Section 19.405(B)(1),
this Section shall take precedence.
          (2) If the Department initially determines the requirements of this chapter are not
met, they shall prepare a notice of intent to deny. This notice will state the
reasons for the Department's denial of the stationary source's submittal.
          (3) Except as provided in Reg. 19.407, the public shall have an opportunity to
comment on the Department's proposed permit decision in accordance with Reg. 19.406.
          (4) Within 90 days of receipt by the Department of an initial permit application, or an
application for a major modification which contains such information as required
by the Department (unless said period is extended by mutual agreement between
the Department and the applicant), the Department shall notify the applicant in
writing of its draft permitting decision. If the Department fails to take action of
the application within the prescribed time frames, the aggrieved applicant may
petition the Commission for relief from Department inaction. The Commission
shall either grant or deny the petition within 45 days of its submittal.
     (C) Final Action
     The Department shall take final action on a permit application after the close of the public
comment period. The Department shall notify in writing the owner/operator and any person that
submitted a written comment, of the Department’s final action and the Department’s reasons for
its final action.

               (d) incorporates a change in the permit involving the retiring of equipment or
emission units, or the decrease of permitted emissions from equipment or
emission units; or
               (e) incorporates a change to the facility’s insignificant activities list.
          (2) The Department shall revise the permit as expeditiously as practicable and may
incorporate such revisions without providing notice to the public.
          (3) The applicant may implement the changes addressed in the request for an
administrative amendment immediately upon approval.
     (B) Change in Ownership
          (1) Permits issued under this regulation shall remain freely transferable, provided the
applicant for the transfer:
               (a) notifies the Director at least thirty (30) days in advance of the proposed
transfer date on such forms as the Director may reasonably require, and
               (b) submits a disclosure statement in accordance with Commission Regulation 8, 
Administrative Procedures, or other such documents as required by the Department.
          (2) The Director may deny the issuance or transfer of any permit, license,
certification, or operational authority if he or she finds, based upon the disclosure
statement and other investigation which he or she deems appropriate, that:
               (a) The applicant has a history of non-compliance with the environmental
laws or regulations of this state or any other jurisdiction;
               (b) An applicant which owns or operates other facilities in the state is not in
substantial compliance with, or on a legally enforceable schedule that will
result in compliance with, the environmental laws or regulations of this
state; or
               (c) A person with a history of non-compliance with environmental laws or
regulations of this state or any other jurisdiction is affiliated with the
applicant to the extent of being capable of significantly influencing the
practices or operations of the applicant which could have an impact upon
the environment.
          (3) Public notice requirements shall not apply to changes in ownership or changes in
name.
     (C) De Minimis Changes
          (1) A proposed change to a facility will be considered De Minimis if:
               (a) minimal judgment is required to establish the permit requirements for the
change; and
               (b) the change will result in a trivial environmental impact.
          (2) The environmental impact of a proposed change generally will be considered
trivial if the emission increase, based on the differences between the sum of the
proposed permitted rates for all emissions units and the sum of previously
permitted emission rates for all units will either:
               (a) be less than the following amounts:
                    i. Seventy-five (75) tons per year of carbon monoxide;
                    ii. Forty (40) tons per year of nitrogen dioxides, sulfur dioxides, or
volatile organic compounds;
                    iii. Twenty-five (25) tons per year of particulate matter emissions;
                    iv. Ten (10) tons per year of direct PM2.5;
                    v. Fifteen (15) tons per year of PM10 emissions; and
                    vi. One-half (0.5) a ton per year of lead;
               (b) or, result in an air quality impact less than:

Pollutant De Minimis
Concentration
Averaging Time
carbon monoxide 500 μg/m3 8-hour
nitrogen dioxide 10 μg/m3 Annual
PM2.5 2 μg/m3 24-hour
PM10 8 μg/m3 24-hour
sulfur dioxide 18 μg/m3 24-hour
lead 0.1 μg/m3 3-month

          (3) A proposed change will be considered De Minimis if the increases are less than
75,000 tpy of CO2e and other pollutant emission increases otherwise qualify as
De Minimis under this section.
          (4) The following changes will not be considered De Minimis changes:
               (a) any increase in the permitted emission rate at a stationary source without
a corresponding physical change or change in the method of operation at
the source;
               (b) any change which would result in a violation of the Clean Air Act;
               (c) any change seeking to change a case-by-case determination of an emission
limitation established pursuant to Best Available Control Technology
(BACT), §112(g), §112(i)(5), §112(j), or §111(d) of the Clean Air Act as
amended as of February 15, 1999;
               (d) a change that would result in a violation of any provision of this
regulation;
               (e) any change in a permit term, condition, or limit that a source has assumed
to avoid an applicable requirement to which the source would otherwise
be subject;
               (f) any significant change or relaxation to existing testing, monitoring,
reporting, or recordkeeping requirements; or
               (g) any proposed change which requires more than minimal judgment to
determine eligibility.
          (5) A source may not submit multiple applications for De Minimis changes that are
designed to conceal a larger modification that would not be considered a De
Minimis change. The Department will require such multiple applications be
processed as a permit modification with public notice and reconstruction
requirements. Deliberate misrepresentation may be grounds for permit
revocation.
          (6) The applicant may implement De Minimis changes immediately upon approval by
the Department.
          (7) The Department shall revise the permit as expeditiously as practicable and may
incorporate De Minimis changes without providing notice to the public. The
applicant may implement De Minimis changes immediately upon approval by the
Department.

     Information which constitutes a trade secret shall be held confidential and segregated from the
public files of the Department if requested in writing by the permit applicant in accordance with
this subsection.
     (A) For purposes of this subsection, “Trade Secret” means any information, including
formula, pattern, compilation, program, device, method, technique, process, or rate of
production that:
          (1) Derives independent economic value (actual or potential) from not being
generally known to, and not being readily ascertainable through, proper means by
other persons who can obtain economic value from its disclosure or use, and
          (2) Is the subject of efforts that are reasonable under the circumstances to maintain its
secrecy.
     (B) In order to establish entitlement to confidentiality, the applicant must submit a sworn
affidavit to the Department that is subject to public scrutiny which describes in a
manner that does not reveal trade secrets, the processes or market conditions that
supports the applicant’s confidentiality claim in the terms of Reg. 19.413(A)(1) and (2). 
This affidavit must also recite the following:
“The applicant agrees to act as an indispensable party and to exercise
extraordinary diligence in any legal action arising from the Department’s denial
of public access to the documents or information claimed herein to be a trade secret.”
If an applicant anticipates numerous permit modifications that may involve regulatory
review of trade secrets, it may submit an omnibus affidavit establishing the prerequisites
of Reg. 19.413(A)(1) and (2) and reference this document in future confidentiality
claims.
     (C) Confidentiality claims shall be afforded interim protected status until the Department
determines whether the requirements of Reg. 19.413(B) are satisfied. The Department
shall make such determination prior to the issuance of any permit or publication of any
draft permit. In the event the Department does not make such determination prior to
permit issuance, the information shall be deemed confidential until a request is made.
If a third party request to review information claimed as confidential is received before
the Department provides its written determination concerning the claim, the
Department shall not release such information before notifying the applicant of the
request. The Department shall notify the applicant of the request and the Department’s
determination on the confidentiality claim at least two business days before releasing
the information, at which time the applicant may choose to supplement its affidavit
supporting confidentiality or seek legal recourse.
     (D) For any permit application submitted subject to a claim of trade secret, the applicant
shall provide two copies of the application; one prominently marked as confidential
and another that is subject to public review with confidential information excised. The
Department will not accept applications that are deemed totally confidential except
under extraordinary circumstances guaranteeing future disclosure at a meaningful time
for public review.

scenarios in the permit.

frame that the Department allows for emergencies. The source and the Department shall attach
each such notice to their copy of the relevant permit. For each such change, the written
notification required above shall include a brief description of the change within the permitted
facility, the date on which the change will occur, any change in emissions, and any permit term
or condition that is no longer applicable as a result of the change.
