Triennial Review

Under the Clean Water Act, a state shall from time-to-time hold public meetings for the purpose of reviewing applicable water quality standards and, as appropriate, modifying and adopting standards. See Chapter 61: Water Quality Standards. This review includes, but is not necessarily limited to:

  • Designated Uses:
    Any water body segment with a water quality standard that does not include A1, B(WW-1) shall be re-examined to determine if there is any new information available.
     
  • Criteria:
    New or old criteria for different constituents
     
  • Antidegradation:
    Protect existing water quality
The steps in this process will include the following: 
     
  • DNR has already met internally with DNR staff and other interested parties from the previous Triennial Review to update them on the status of the 2011 Triennial Review Work Plan. 
             
  • DNR will meet with external stakeholder groups to understand their interests and concerns.  
         
  • Concurrently, the department will then seek public input regarding the Water Quality Standards by holding public meeting(s) in the six field office regions and listen to and obtain the interests of the public in regards to water quality standards.
     
  • After all the public comments have been received, the department will consider this information and use it in determining a prioritized work plan for the 2015 - 2017 period.   
     
  • A Draft Triennial Review Process Summary and Work Plan will be prepared that identifies the selected goals for the next three years and details the process the department used to reach this determination.  A request for public feedback will be conducted and feedback received.  A Responsiveness Summary will also be prepared to address those comments. 
     
  • The Triennial Review process and its final results will be detailed in the Final Triennial Review Process Summary and Work Plan.  A link to those document will be provided after they are prepared. 

Links to the documents relating to the previous 2012-2014 Triennial Review period are below.  For those that would like to skip to just the final determinations, a Work Plan Only document has also been included.
