The DEQ's Water Resources Division (WRD), has launched a new information system called MiWaters. MiWaters is a web-based permitting and compliance database. MiWaters establishes a streamlined electronic permitting process, allowing Michigan to fulfill federal electronic reporting requirements and providing an online component for access to public information. The focus of MiWaters is permitting and compliance, including National Pollutant Discharge Elimination System (NPDES) Permits (including Pesticide permits).
One of our focuses in developing MiWaters is to create a system that makes it easier for the WRD to communicate with, and provide services electronically to, our regulated community. Below is a list of some of the functions and features that MiWaters provides:
- Permit applications will be submitted electronically.
- The Electronic Environmental Discharge Monitoring Reporting (e-DMR) system is replaced with a more sophisticated system that will provide additional validation and feedback to permittees, and help detect and prevent errors prior to submittal.
- All permit-required submittals will be submitted electronically.
- Those with a MiWaters account will be able to manage permissions, deciding who can view, edit, and submit applications or submittals.
- MiWaters will provide near real-time notifications, to the permittee, of any violations determined by the system or by staff, providing permittees with an early "heads up" and opportunity to correct problems.
MiWaters training information is available as seminars, webinars, and videos.
*Paper Annual Report Forms are no longer accepted now that MiWaters is implemented.*

In addition, any water treatment additive (WTA) that is discharged to a surface water of the state from an National Pollutant Discharge Elimination System (NPDES) permitted discharge requires prior review and approval by the WRD. Pesticides used for controlling mosquito larvae in waters discharged under NPDES permits are considered WTAs. Requests to perform pesticide treatment in wastewater treatment systems and catch basins covered by an NPDES permit must originate from the permittee and be made under the Water Treatment Additive approval process.
For applications of pesticides to catch basins and/or waters in a storm sewer system or wastewater treatment system that are covered by a National Pollutant Discharge Elimination System (NPDES) permit, an approval under the Water Treatment Additive approval process is necessary. This includes municipalities, industries and storm water sewer systems under the Phase I and Phase II storm water regulations.
