# PART I: STANDARD CONDITIONS 

**ALL CONDITIONS IN THIS PERMIT ARE FEDERALLY ENFORCEABLE UNLESS
EXPLICITLY DENOTED OTHERWISE.** *\[Authority: AQR § 19.4.2 (Amended
07/01/04)\]*

A-1. In the event of any changes in control or ownership of the
facility, all conditions in this permit shall be binding on all
subsequent owners and operators, upon execution of an administrative
permit amendment. *\[Authority: AQR § 19.5.4.1.d (Amended 07/01/04)\]*

A-2. This operating permit has a fixed term not to exceed five (5)
years. The Part 70 permit issuance date is the beginning of the permit
term. *\[Authority: AQR § 19.4.1.2 (Amended 07/01/04)\]*

A-3. If any term or condition of this permit becomes invalid as a result
of a challenge to a portion of this permit, the other terms and
conditions of this permit shall not be affected and shall remain valid.
*\[Authority: AQR § 19.4.1.5 (Amended 07/01/04)\]*

A-4. The owner/operator shall comply with all terms and conditions of
this permit. Any permit noncompliance constitutes a violation of the
Clean Air Act (Act) and is grounds for enforcement action; for permit
termination, suspension, reopening, or amendment; or for denial of a
permit renewal application. *\[Authority: AQR § 19.4.1.6.a (Amended
07/01/04)\]*

A-5. The owner/operator shall not use as a defense in an enforcement
action that it would have been necessary to halt or reduce the permitted
activity to maintain compliance with the terms and conditions of this
permit. *\[Authority: AQR § 19.4.1.6.b (Amended 07/01/04)\]*

A-6. The permit may be modified, revoked, reopened, and reissued, or
terminated for cause. The filing of a request by the owner/operator for
the permit modification, revocation, reissuance, or termination, or of a
notification of planned changes or anticipated noncompliance does not
stay any permit condition. *\[Authority: AQR § 19.4.1.6.c (Amended
07/01/04)\]*

A-7. The permit does not convey any property rights of any sort, or any
exclusive privilege. *\[Authority: AQR § 19.4.1.6.d (Amended
07/01/04)\]*

A-8. The owner/operator shall furnish to the Control Officer, within a
reasonable time, any information that the Control Officer may request in
writing to determine whether cause exists for modifying, revoking and
reissuing, or terminating the permit or to determine compliance with the
permit. Upon request, the owner/operator shall also furnish to the
Control Officer copies of records required to be kept by the permit or,
for information claimed to be confidential, the owner/operator may
furnish such records directly to the Administrator along with a claim of
confidentiality. *\[Authority: AQR § 19.4.1.6.e (Amended 07/01/04)\]*

A-9. Requirements for compliance certification with terms and conditions
contained in the operating permit, including emission limitations,
standards, or work practices, are as follows:

> a\. compliance certifications shall be submitted annually in writing
> to the DAQEM Compliance Reporting Supervisor and the Administrator at
> USEPA Region 9 by the owner/operator. A compliance certification is
> due on January 30 of each year;
>
> b\. compliance shall be determined in accordance with the requirements
> detailed in AQR § 19.4.1.3 (Amended 07/01/04), record of periodic
> monitoring, or any credible evidence; and
>
> c\. the compliance certification shall include:
>
> i\. identification of each term or condition of the permit that is the
> basis of the certification;
>
> ii\. the source\'s compliance status and whether compliance was
> continuous or intermittent;
>
> iii\. methods used in determining the compliance status of the source
> currently and over the reporting period consistent with Subsection
> 19.4.1.3; and
>
> iv\. other specific information required by the Control Officer to
> determine the compliance status of the source. *\[Authority: AQR §
> 19.4.3.5 (Amended 07/01/04)\]*

A-10. The owner/operator shall not make a Modification, as defined in
AQR Section 0, to the existing facility prior to receiving an Authority
to Construct Certificate (ATC) from the Control Officer. *\[Authority:
AQR § 12.1.1.1 (Amended 10/07/04)\]*

A-11. Any request for a Part 70 permit modification must comply with the
requirements of AQR Section 12, Section 55 and AQR Subsection 19.5.5.
*\[Authority: AQR § 12.1 (Amended 10/07/04), AQR § 55 (Amended 12/21/04)
and AQR § 19.5.5.1 (Amended 07/01/04)\]*

A-12. Application for permit renewal shall be deemed timely if a
complete application is submitted between six months and 18 months prior
to the date of permit expiration. *\[Authority: AQR § 19.3.1.1.c
(*Amended *07/01/04)\]*

A-13. Any applicant who fails to submit any relevant facts or who has
submitted incorrect information in a permit application shall, upon
becoming aware of such failure or incorrect submittal, promptly submit
such supplementary facts or corrected information. *\[Authority: AQR §
19.3.2 (Amended 07/01/04)\]*

A-14. An emergency, as defined in Section 0 of the AQR (Amended
10/07/04), can constitute an affirmative defense to actions brought for
noncompliance with a technology-based standard provided the properly
signed contemporaneous operating logs or other relevant evidence
demonstrate:

> a\. an emergency occurred and that the owner/operator can identify the
> cause(s) of the emergency;
>
> b\. the permitted facility was properly operated during claimed
> emergency;
>
> c\. the owner/operator took all reasonable steps to minimize levels of
> emissions that exceeded the emission standards or other requirements
> in the permit during the period of the emergency; and
>
> d\. the owner/operator submitted notice of the emergency to the
> Control Officer within one (1) hour of the time when emission
> limitations were exceeded due to the emergency. This notice must
> contain a description of the emergency, any steps taken to mitigate
> emissions, and corrective actions taken. *\[Authority: AQR § 19.4.7.1
> (Amended 07/01/04)\]*

A-15. In any enforcement proceeding, the owner/operator has the burden
of proof in seeking to establish the occurrence of an emergency.
*\[Authority: AQR § 19.4.7.2 (Amended 07/01/04)\]*

A-16. The owner/operator may request confidential treatment of any
records in accordance with Subsection 19.3.1.3 of the Department of Air
Quality and Environmental Management (DAQEM) regulations. Emission data,
standards or limitations \[all terms as defined in 40 CFR § 2.301(a)\]
or other information as specified in 40 CFR § 2.301 shall not be
considered eligible for confidential treatment. The Administrator and
the Control Officer shall each retain the authority to determine whether
information is eligible for confidential treatment on a case-by-case
basis. *\[Authority: AQR § 19.3.1.3 (Amended 07/01/04) and 40 CFR §
2.301\]*

A-17. Permit fees, including annual emission fees, shall be determined
pursuant to Section 18 of the AQR (Amended 01/20/06). Failure to pay
Part 70 permit fees may result in citations or suspensions or revocation
of the Part 70 Permit. *\[Authority: AQR § 19.4.1.7 (Amended
07/01/04)\]*

A-18. The owner/operator shall allow the Control Officer or an
authorized representative, upon presentation of credentials:

> applicable requirements. *\[Authority: AQR §§ 4.3 (Amended 07/01/04)
> and 19.4.3.2 (Amended 07/01/04)\]*

A-19. The Control Officer at any time may require from any person such
information or analyses as will disclose the nature, extent, quantity or
degree of air contaminants which are or may be discharged by such
source, and type or nature of control equipment in use, and may require
that such disclosures be certified by a professional engineer registered
in the state. In addition to such report, the Control Officer may
designate an authorized agent to make an independent study and report as
to the nature, extent, quantity or degree of any air contaminants which
are or may be discharged from source. An authorized agent so designated
is authorized to inspect any article, machine, equipment, or other
contrivance necessary to make the inspection and report. *\[Authority:
AQR § 4.4 (Amended 07/01/04)\]*

A-20. The Control Officer may require any person responsible for
emission of air contaminants to test or have tests performed to
determine the emissions of air contaminants from any source whenever the
Control Officer has reason to believe that an emission in excess of that

be necessary for proper determination of the emission of air
contaminants. *\[Authority: AQR § 4.6 (Amended 07/01/04)\]*

A-22. It is unlawful for any person:

> a\. to hinder, obstruct, delay, resist, interfere with, or attempt to
> interfere with the Control Officer, or any individual to whom
> authority has been duly delegated for the performance of any duty by
> the AQR;
>
> b\. to refuse to permit the Control Officer, or any individual to whom
> such authority has been delegated, to administer or perform any
> function provided for herein by refusing him/her at any reasonable
> time entrance to property or premises, except a private residence,
> containing equipment or open fire, discharging, or suspected and
> believed to be discharging, smoke, dust, gas, vapor, or odor into the
> open air; and
>
> c\. to fail to disclose information when requested, under oath or
> otherwise, to the Control Officer or any individual to whom such
> authority has been delegated. *\[Authority: AQR §§ 5.1, 5.1.1, 5.1.2,

punishment imposed by and under the AQR. *\[Authority: AQR § 8.1
(Amended 07/01/04)\]*

A-24. It shall be a defense to any prosecution instituted against any
employee of a person owning, operating, or conducting any business,
industry, or operation that the acts complained of were done and
performed pursuant to the orders and directions of such owner or
operator, or his agent or representative, conducting such business,
industry or operation. *\[Authority: AQR § 8.2 (Amended 07/01/04)\]*

A-25. Any person who violates any provision of this operating permit,
including, but not limited to, any application requirement; any permit
condition; any fee or filing requirement; any duty to allow or carry out
inspection, entry or monitoring activities or any requirements by DAQEM
is guilty of a civil offense and shall pay civil penalty levied by the
Hearing Board of not more than \$10,000. Each day of violation
constitutes a separate offense. *\[Authority: AQR § 9.1 (Amended
07/01/04)\]*

A-27. The owner/operator shall not build, erect, install or use any
article, machine, equipment or other contrivance, the use of which,
without resulting in a reduction in the total release of air
contaminants to the atmosphere, reduces or conceals an emission, which
would otherwise constitute a violation of the AQR. This condition shall
not apply to cases of AQR Section 40. *\[Authority: AQR § 80.1 (Amended
07/01/04) and 40 CFR § 60.12\]*

name of the responsible official certifying compliance and the date of
signature. *\[Authority: AQR § 19.3.4 (Amended 07/01/04)\]*

A-29. Permit expiration terminates the owner/operator's right to operate
unless a timely and complete renewal application has been submitted
consistent with AQR Subsections 19.3.1.d and 19.5.2 in which case the
permit shall not expire and all terms and conditions of the permit shall
remain in effect until the renewal permit has been issued or denied.
*\[Authority: AQR § 19.5.3.2 (Amended 07/01/04)\]*

A-30. This permit can be reopened for any of the following conditions:

> a\. additional applicable requirements under the Act become applicable
> with a remaining permit term of three (3) or more years. Such a
> reopening shall be completed within eighteen (18) months after
> promulgation of the applicable requirement. No such reopening is
> required if the effective date of the requirement is later than the
> date on which the permit is due to expire, unless the original permit
> or any of its terms and conditions have been extended;
>
> b\. the Control Officer or EPA determines that the permit contains a
> material mistake or that inaccurate statements were made in
> establishing the emission standards or other terms or conditions of
> the permit;
>
> c\. the Control Officer or EPA determines that the permit must be
> revised or revoked to assure compliance with the applicable
> requirements; and
>
> d\. in addition to items a. through c. above, the Control Officer may
> reopen a permit of his/her own accord or in response to a written
> request from any person if he/she determines that there are grounds
> for reopening and such grounds arose entirely after the deadline set
> forth in AQR § 7.10.2.3. *\[Authority: AQR § 19.5.6.1 (Amended
> 07/01/04)\]*

A-31. Proceedings to reopen and issue a permit shall follow the same
procedure that applies to initial permit issuance and shall affect only
those parts of the permit for which cause to reopen exists.
*\[Authority: AQR § 19.5.6.2 (Amended 07/01/04)\]*

1.  A-32. Any person operating any article, machine, equipment, or other
    contrivance for which registration is required by these Regulations,
    shall permit the Control Officer, or his agent, to install and
    maintain sampling and testing facilities as are reasonable and
    necessary for measurement of emissions of air contaminants. Where
    existing facilities for sampling or testing are inadequate, the
    Control Officer may, in writing, require the Owner/Operator to
    provide and maintain access to such facilities as are reasonably
    necessary for sampling and testing purposes by the Control Officer,
    or his authorized agent, in order to secure information that will
    disclose the nature, extent, quantity, or degree of air contaminants
    discharged into the atmosphere from the article, machine, equipment,
    or other contrivance described in the Registration form or records.
    *\[Authority: AQR § 24.1 (Amended 07/01/04)\]*
