Permit Terms and Conditions

The following applies to each permittee and permitted source with respect to only the affected emissions units 

and any associated air pollution control technologies in that permitted source’s Approval of the Request for 

Coverage.

Section 1 – General Provisions

1. Construction and Operation 

The permittee shall construct or modify and shall operate the affected emissions units and any associated 

air pollution control technologies in compliance with this permit and all other applicable federal air quality 

regulations; and in a manner consistent with representations made by the permittee in the Request for 

Coverage, to the extent the reviewing authority relies upon these representations in issuing the Approval of 

the Request for Coverage. 

2. Locations 

This permit only authorizes the permittee to construct or modify and to operate the permitted source in the 

location(s) listed in the reviewing authority’s Approval of the Request for Coverage for that permitted 

source.

3. Liability 

This permit does not release the permittee from any liability for compliance with other applicable federal 

and tribal environmental laws and regulations, including the CAA. 

4. Severability 

The provisions of this permit are severable. If any portion of this permit is held invalid, the remaining 

terms and conditions of this permit shall remain valid and in force. 

5. Compliance 

The permittee must comply with all provisions of this permit, including emission limitations that apply to the 

affected emissions units at the permitted source. Noncompliance with any permit provision is a violation of 

the permit and may constitute a violation of the CAA; is grounds for an enforcement action; and is grounds 

for the reviewing authority to revoke the Approval of the Request for Coverage and terminate the permitted 

source’s coverage under this general permit. 

6. National Ambient Air Quality Standards (NAAQS)/Prevention of Significant Deterioration (PSD) Protection 

The permitted source must not cause or contribute to a NAAQS violation or, in an attainment area, must not 

cause or contribute to a PSD increment violation. 

7. Unavailable Defense 

It is not a defense for the permittee in an enforcement action that it would have been necessary to halt or 

reduce the permitted activity in order to maintain compliance with the provisions of this permit. 

8. Property Rights

The permit does not convey any property rights of any sort or any exclusive privilege.

and reissuing, or terminating the permit or to determine compliance with the permit. For any such 

information claimed to be confidential, the permittee must submit a claim of confidentiality in accordance 

with 40 CFR part 2 subpart B. 

10. Inspection and Entry

Upon presentation of proper credentials, the permittee must allow a representative of the reviewing 

authority to:

a. Enter upon the premises where a permitted source is located or emissions-related activity is conducted 

or where records are required to be kept under the conditions of the permit;

b. Have access to and copy, at reasonable times, any records that are required to be kept under the

compliance with the permit or other applicable requirements and

e. Record any inspection by use of written, electronic, magnetic and photographic media.

11. Posting of Coverage 

This general permit, and the most current Approval of the Request for Coverage for the permitted 

source, must be posted prominently at the facility, and each affected emissions unit and any associated 

air pollution control technology must be labeled with the identification number listed in the Approval of 

the Request for Coverage for that permitted source. 

12. Duty to Obtain Source-specific Permit 

If the reviewing authority intends to terminate a permitted source’s coverage under this general permit for 

cause as provided in Section 6 of this general permit, then the permittee shall apply for and obtain a caseby-case permit under 40 CFR 49.155 as required by the reviewing authority. 

13. Credible Evidence

For the purpose of establishing whether the permittee violated or is in violation of any requirement of this 

permit, nothing shall preclude the use, including the exclusive use, of any credible evidence or information 

relevant to whether a permitted source would have been in compliance with applicable requirements if the 

permittee had performed the appropriate performance or compliance test or procedure.

Section 7: Obtaining Coverage under this General Permit

58. To obtain coverage under this general permit, an applicant must submit a Request for Coverage to the 

appropriate reviewing authority for the area in which the permitted source is or will be located. Attachment 

D contains a list of reviewing authorities and their area of coverage. 

59. If the plant will locate in area covered by more than one reviewing authority, the applicant need only submit 

a Request for Coverage to one reviewing authority with regard to all intended locations of operation. The 

Request for Coverage must contain the information requested in the standard application form for this 

permit. You must also submit a copy of the Request for Coverage to the Indian governing body for any area 

in which the permitted source will operate.
