Storm Events – What They Are & How to Tackle Them

One of the most important requirements of your Construction Generic Permit (CGP) is the NPDES Stormwater Inspections. In the State of Florida, NPDES inspections have 2 components: routine inspections and storm event inspections. So—what is the difference between them? A big difference between the two is frequency. Routine inspections must be conducted once every 7 days, not once a calendar week. There should never be a lapse of more than 7 days between routine inspections.

Storm event inspections are weather-dependent. A storm event is classified as rainfall event with greater than 0.5 inches of rain. A storm event must not have period greater than 4 hours between rainfall events. For example, imagine if it were to rain 0.3 inches from 2:00-3:00pm. It then rains again, later in the evening, an additional 0.3 inches from 9:00-11:00pm. This would not be a storm event because there are more than 4 hours between the end of the initial rainfall and the beginning of the second rainfall. Therefore, it was not a storm event dropping 0.6 inches of rain, it was two separate rainfall events dropping 0.3 inches each.

An important requirement to storm events is that an NPDES inspections must be conducted on site within 24 hours of the end of a storm event. The State of Florida does not make exceptions for weekends or holidays. The good news is that neither does KCI.
