The narrative statement must demonstrate the applicant's capability consistent with the applicable provisions of the Clean Air Act and implementing regulations and, if requested by the Regional Administrator, may include:

A tribe relying on a consortium in this manner must provide reasonable assurances that the tribe has responsibility for carrying out necessary functions in the event the consortium fails to.

(6) Where applicable Clean Air Act or implementing regulatory requirements mandate criminal enforcement authority, an application submitted by an Indian tribe may be approved if it meets the requirements of § 49.8.

(8) Where the applicant has previously received authorization for a Clean Air Act program or for any other EPA-administered program, the applicant need only identify the prior authorization and provide the required information which has not been submitted in the previous application.

(b) A tribe may simultaneously submit a request for an eligibility determination and a request for approval of a Clean Air Act program.

(c) A request for Clean Air Act program approval must meet any applicable Clean Air Act statutory and regulatory requirements.
