New Kansas Industrial Discharge Permit

The Kansas General Permit for Stormwater Runoff Associated with Industrial Activities became effective on November 1, 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 must complete the new Notice of Intent (NOI) form to apply for and obtain coverage under the industrial stormwater general permit S-ISWA-1611-1.
Facilities that currently have industrial stormwater discharge coverage under the previous Kansas General Permit 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, 2017 and must continue to comply with the conditions of the previous general permit until the individual permit is issued.


The principal requirement of the Kansas General Permit for Stormwater Runoff from Industrial Activity has remained the same - for the owner to develop, implement and maintain a Stormwater Pollution Prevention Plan (SWPPP). Caltha LLP has prepared a SWPPP Template to align with the 2016 Kansas permit requirements.

2017 Georgia General Pemit | What If I Exceeded Benchmarks Under Current Permit?

The current Georgia industrial stormwater general discharge permit expires on May 30, 2017. The revised NPDES General Storm Water Permit For Discharges of Stormwater Associated With Industrial Activity (2017 IGP) was finalized in 2016 and becomes effective on June 1, 2017. The revised permit made some modifications to requirements permitted facilities must meet, but not as substantial of changes as compared to the release of the 2012 IGP.

If a facility exceeded the impaired waters benchmark based on the criteria presented in 2012 IGP permit, then the facility has the option to conduct 12 months of flow-weighted composite sampling to demonstrate the discharge does not cause or contribute to an exceedance of water quality standards, or make the necessary improvements to the facility to achieve the instream water quality standard as an effluent limit within 36 months. If the facility still is unable to meet the impaired waters benchmark(s), they may not be authorized to discharge stormwater under this permit and may be required to apply for an individual NPDES permit or alternative general permit. Facilities that failed to meet the applicable benchmarks of the 2012 IGP permit have the option to sample their discharge(s) for 12 months to confirm whether the facility causes or contributes to an exceedance of the applicable Water Quality Standard, or prevent all exposure of industrial processes, materials, and equipment to stormwater, and/or capture and treat storm events of up to 1.2 inches within industrial areas exposed to stormwater within 36 months.
