the Operation and Maintenance Plan meets the requirements of Section 402 not

later than 30 days after receipt of the Plan, or within a longer period of time

agreed upon by the parties. The Air Pollution Control Officer shall approve an

Operation and Maintenance Plan unless it fails to demonstrate continuous

operations of the emissions control equipment during periods of emissions
