(2) Complied with the requirements of § 270.10 governing submission of part A applications;
(b) Failure to qualify for interim status. If EPA has reason to believe upon examination of a part A application that it fails to meet the requirements of § 270.13, it shall notify the owner or operator in writing of the apparent deficiency. Such notice shall specify the grounds for EPA's belief that the application is deficient.

If, after such notification and opportunity for response, EPA determines that the application is deficient it may take appropriate enforcement action.
