Industrial Programs Section Stormwater Program

There are three types of stormwater Permits: Construction, Industrial and Municipal Separate Storm Sewer System/MS4.

The Stormwater Program at KDHE is administered jointly by the Industrial and Municipal Programs Sections within the Bureau of Water. The Industrial Programs Section issues permits for stormwater discharges associated with construction and industrial activities and the Municipal Programs Section issues permits for the MS4 systems.

Construction Stormwater

KDHE has reissued the Kansas General Permit for Stormwater Runoff from Construction Activities effective August 1, 2022. The new permit expires July 31, 2027 and replaces the previous general permit which expired July 31, 2022. Projects authorized prior to August 1, 2022 may operate under the previous general permit for 18 months, ending January 31, 2024. If these projects are not terminated by January 31, 2024, they must meet the requirements of the new general permit.

Coverage under this NPDES general permit authorizes the discharge of stormwater runoff from construction activities for sites where the discharge point is located in Kansas and for discharges and construction activities that are conducted in accordance with the provisions and requirements of this permit and in accordance with a site specific stormwater pollution prevention plan. Coverage continues from the date of Authorization until the site is stabilized and the construction stormwater discharge Notice of Termination (NOT) is received by KDHE or the permit is revoked/terminated for cause by KDHE.

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 under the Stormwater Runoff from Construction Activities General Permit S-MCST-2208-1. Construction activities consist of any activity (e.g. clearing, grubbing, excavating, and grading) which disturb a cumulative total of one (1.0) or more acres or when the site is a part of a larger common plan of development or sale which will disturb a cumulative total of one or more acres.

Owners or operators of construction activities which disturb less than one acre (<1.0 acre), and which are not part of a larger common plan of development or sale, must have authorization to discharge stormwater runoff from construction activities under this NPDES general permit when KDHE notifies the owner or operator that the water quality impact from discharge of stormwater runoff from construction activity warrants consideration because the proposed construction activities constitute a significant pollution potential.
