During this reporting period, the EPA expects to receive approximately 4,000 emissions data submissions. Sources are encouraged to begin working on their submissions as early as possible in order to give them sufficient time to complete all submissions by the deadline.

If you wait until later in the month to begin working with your data and you run into problems that require technical support, your request will be added to a much longer queue of technical support requests.
