How long is my NPDES stormwater individual permit valid?

The MS4 individual permits expire after a term of five years, requiring re-application efforts to continue coverage (see Rule 62-624.420 F.A.C.) (Note: Permit effectiveness is continued by the timely filing of a renewal application.)

How do I re-apply for permit coverage?

You may re-apply for permit coverage concurrently with a timely filing of the fourth year annual report, or, as an alternative, you may re-apply by submitting an application 180 days prior to the expiration of the permit. The required contents of a re-application are specified in Rule 62-624.440 F.A.C..

What does "reserved" mean as it appears in my permit?

When used in a permit, the term "reserved" is simply a place holder to let the permittee know that no requirement is being imposed at this time but some condition or requirement might be imposed in the future for that specific subject area.

How do I submit an annual report? 

Annual Report Forms are located in the DEP Public Files. Annual reports should be mailed or emailed to the MS4 Coordinator.
