Construction Stormwater Program

The purpose of the construction stormwater program is to protect the waters of the State from contamination. Owners or operators of any project or combination of projects who engage in construction activities which will disturb one or more acres must have authorization to discharge stormwater runoff under the construction stormwater general permit S-MCST-1703-1. Anyone who disturbs less than one acre may require authorization to discharge stormwater runoff when KDHE believes the water quality impact warrants consideration.

Application for the construction stormwater permit is made by completing a Notice of Intent (NOI) form which should be submitted at least 60 days before the start of the scheduled construction to avoid any unplanned delays. The permit fee for this general permit for stormwater runoff from construction activity is $60 per year. The primary requirement of the general permit is for the permittee to develop and implement a Stormwater Pollution Prevention (SWP2) plan. When the soil disturbing activity is completed and final stabilization of the site is achieved, the permittee must notify KDHE to terminate the authorization to discharge.
