Note: This is a PROPOSED GENERAL PERMIT. No discharges are authorized under this permit at this time.
The department is developing a new general permit. Proposed General Permit #9 (GP9) would authorize discharges from the following activities:
Proposed GP9 would cover dewatering discharges to surface waters of the state and to the ground surface. Discharges from geothermal systems that do not reach navigable waters are already exempted by rule from obtaining operation permits. Therefore, only discharges to navigable waters from residential geothermal systems will by authorized by GP9.
Please use the links below to view proposed General Permit #9, the changes made to GP9 in response to public comments, and the permit rationale.

General Permit 8 & 9 Responsiveness Summary - March 26, 2018
Two documents have been developed to help people determine what GP9 requirements are applicable in a given situation. The GP9 Matrix is a series of yes/no questions. As you answer each question, you will be directed to the next applicable question. You may prefer this if you are a linear thinker or like flow charts. The GP9 Requirements Summary has all the requirements laid out in one document, so you can easily find the requirements for your situation. You may prefer this if you are a visual thinker, or if you wish to compare requirements among different situations.
General Permit #9 Decision Matrix
General Permit #9 Requirements Summary
Currently, people conducting discharges that would be authorized by GP9 can either pursue an individual permit or discharge illegally. Obtaining an individual permit requires an investment of time and money that is disproportionate to the impact these discharges usually have on the environment. Not only is discharging without a permit illegal, but the discharges may occur without environmental controls. DNR receives many requests for guidance from those who are interested in avoiding negative environmental impacts.
Proposed General Permit #9 will benefit dischargers by providing them a permit shield without the time and cost of obtaining an individual permit. Unlike individual permits, no fees are associated with GP9. It will also provides dischargers with guidance for minimizing the impact of discharges on water quality. Proposed GP9 will benefit the environment by providing requirements and guidance for conducting these discharges in a manner that will avoid negative impacts on water quality. Proposed GP9 will benefit DNR by providing a mechanism to authorize these discharges using very little staff time, which can then be spent on higher-risk discharges.
What GP9 will do:
General permits must be adopted into rule and discharges authorized by the permits must be added to the list at 567 IAC 64.3(4).
The Notice of Intended Action for Proposed General Permits #8 and #9 was approved by the Environmental Protection Commission (EPC) on January 17th. The Notice was published in the Iowa Administrative Bulletin on February 14th as ARC 3625C.
The Administrative Rules Review Committee (ARRC) took no action on the rules at its meeting on March 9, 2018. The final general permits and rules were presented to the EPC at their meeting on April 17, 2018, and published in the Iowa Administrative Bulletin as ARC 3786C on May 9, 2018.
Three public hearings were held in March 2018, and written comments were accepted until March 19th. The Responsiveness Summary addressing all of the comments regarding GP9 is included to the left with the other General Permit 8 & 9 rulemaking documents.
