Industrial Stormwater Permit and Associated Forms

General Information

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 reissued the Kansas General Permit for Stormwater Runoff Associated with Construction Activities on January 2, 2007. The new permit expires December 31, 2011. Owners or operators of any project or combination of projects who engage in construction activities which will disturb one (1) or more acres must have authorization to discharge stormwater runoff under the construction stormwater general permit S-MCST-0701-1.

Major modifications in the reissued permit include the removal of references to large construction activity (5 acres or more) as all construction activity of one (1.0) acre or more of soil disturbance now requires authorization to discharge stormwater runoff, clarification on a complete Notice of Intent submittal, redefining the termination criteria for subdivision projects, and various wording changes to clarify permit requirements.

Industrial Stormwater:

KDHE has reissued the Kansas General Permit for Stormwater Runoff Associated with Industrial Activity effective November 1, 2011 through October 31, 2016.  The reissued permit and forms contain new and additional requirements.

Owners or operators of new or existing unpermitted facilities subject to regulation of stormwater runoff associated with industrial activity as defined in 40 CFR 122.26(b)(14) or are otherwise designated by KDHE must utilize the new Notice of Intent (NOI) form to apply for and obtain coverage under the industrial stormwater general permit S-ISWA-1111-1. 

Facilities that currently have industrial stormwater discharge coverage with an Authorized Notice of Intent (NOI) from the previous Kansas General Permit for Stormwater Runoff Associated with Industrial Activity (effective September 1, 2006 through August 31, 2011), S-ISWA-0507­-1, do not need to submit a new NOI, but need to comply with the requirements of the new general permit.  Existing permitted facilities that wish to decline coverage under the new permit must submit an application for coverage under an individual permit by February 1, 2012 and must continue to comply with the conditions of the previous general permit until the individual permit is issued.

Existing facilities that have not submitted an NOI form and obtained coverage under the previous Kansas General Permit for Stormwater Runoff Associated with Industrial Activity do not have authorization to discharge stormwater from industrial activities.  Facilities that have submitted historical individual applications, EPA group applications, or Notice of Intent (NOI) forms in the past but have not received an Authorized NOI since September 1, 2006 will be contacted in the near future regarding coverage under the new Kansas/NPDES general permit for stormwater runoff from industrial activities.

The principal requirement of the Kansas General Permit for Stormwater Runoff from Industrial Activity is for the owner to develop and implement a Stormwater Pollution Prevention plan.

Municipal Separate Storm Sewer Systems (MS4s):

The Municipal Programs Section permits the municipal separate storm sewer systems (MS4s). The permits are divided into Phase I and Phase II permits. Kansas issued three Phase I MS4 permits to communities serving populations of 100,000 or greater: The three Phase I permits were issued to Topeka, Wichita and the Unified Government of Wyandotte County & Kansas City. A total of 61 Phase II permits have been issued to 57 different MS4s. Five separate Phase II permits were issued to the Kansas Department of Transportation (KDOT) to provide permit coverage in the five urbanized areas. The five urbanized areas in Kansas are Wichita, Topeka, Lawrence, Kansas City Missouri- Kansas and St. Joseph Missouri-Kansas. A list of the Phase I & 2 MS4s is available on the KDHE website. Contact Rance Walker (785) 296-5537 for MS4 permit questions.

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 (1) or more acres must have authorization to discharge stormwater runoff under the construction stormwater general permit S-MCST-0701-1. Anyone who disturbs less than one acre may require authorization to discharge stormwater runoff when KDHE believes the water quality impact warrants consideration. All Municipal Separate Storm Sewer System (MS4) operators previously exempt from construction stormwater permitting requirements must now also apply for authorization to discharge stormwater runoff from construction activities under the requirements of this general NPDES permit.

Application for the construction stormwater permit is made by completing a Notice of Intent (NOI) form at least 60 days before starting construction. 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.
