The department is developing a new general permit. This permit would authorize discharges from the following activities:
The permit 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 the new permit.
Draft General Permit #9 – October 12, 2017
Currently, people conducting discharges that would be authorized by the permit 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.
This permit 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 GP#9. It also provides dischargers with guidance for minimizing the impact of these discharges on water quality. This permit will benefit the environment by providing requirements and guidance for conducting these discharges in a manner that will avoid negative impacts on water quality. This permit 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.
General permits must be adopted into rule. Most importantly, the discharges authorized by the permit must be added to the list at 567 IAC 64.3(4) and the permit must be added to the list of general permits at 567 IAC 64.15. Other rule changes may also be necessary. This page will be updated as rulemaking proceeds.
DNR has held three stakeholder meetings on the draft permit. The presentation and notes from the stakeholder meetings are linked below.
