Who Needs Construction Stormwater Permit coverage?
Please answer the following questions:
- Does your construction project disturb 1 or more acres of land
through clearing, grading, excavating, or stockpiling of fill material?
Remember to count the cumulative acreage of the entire project whether in a
single or in a multiphase project. This applies even if you are
responsible for only a small portion (less than one acre) of the larger
project planned over time.
- Is there any possibility that stormwater could run off your site during construction and into surface
waters or conveyance systems leading to surface waters of the state? In
almost every case, the answer to this question is yes. However, if the
topography and location of your site is such that there is no possibility
that rainfall or snowmelt could leave the site or enter a waterway, you do
not need permit coverage.
If you answered "yes" to both of these questions, your construction
site needs a permit. Construction site operators must apply for
a permit 60 days prior to discharging stormwater.
