All facilities requiring permit coverage must assess for industrial activities and materials, and consider the potential pollutants that can come from these activities and materials. Choose the best stormwater control measures for your facility, so that you do not discharge contaminated stormwater to the ground or surface waters.
How do I choose stormwater control measures?
Identifying control measures that you will install at your facility is a SWPPP requirement. You are not required to have structural BMPs implemented by the time you apply for permit coverage.You must document in your SWPPP which ones you will be utilizing at your facility.

Many of the recommendations for No Exposure offer ideas for non-structural and simple structural control measures that can be implemented at your facility.

Start with the simple BMPs first, such as moving materials indoors or under cover.
