Air quality plan approval is required for the applicant to commence construction of an air contamination source and may allow for temporary operation. A plan approval is not the same as an operating permit, which is required for long-term operation. Publication of a draft air quality plan approval and notice of intent signals that DEP has performed its evaluation of the application and begins the regulatory public participation process.
