Construction sites have the potential to impact Kansas’s waters through runoff of rainwater containing sediment and other pollutants. Construction sites can cause long term land use changes that alter hydrology and pollutant loading of local streams. The KDHE BOW Industrial Program Unit administers a Construction Stormwater Permit to require best management practices that keep pollutants from running off a site and affecting nearby properties and surface water bodies.
If your construction project disturbs one or more acres of ground, you must get a permit to discharge stormwater from your site. If your project disturbs less than one acre, but is part of a larger plan of development that will ultimately disturb more than one acre, you also need a permit to discharge stormwater from the site.
Soil disturbing activities where contaminated soils or contaminated groundwater may be present on the site are reviewed by KDHE on a case-by-case basis and may require coverage under this NPDES general permit or an individual permit even if less than one acre (< 1.0 acre) of soil is disturbed.
Construction Stormwater Permits require coverage through submittal of a Notice of Intent (NOI) to the KDHE BOW Industrial Program Unit as well as the development and implementation of a Stormwater Pollution Prevention Plan.
To submit an NOI application visit the Kansas Environmental Information Management System (KEIMS).
The Construction Stormwater General Permit can be found here.
Contact the KDHE BOW Industrial Program Unit with questions on exemptions.
Proceed to evaluate your facility’s construction stormwater permit needs.
