Review of modified Class 2 and Class 7 waters

The Clean Water Act directs states to review all waters in accordance with the provisions of 40 CFR §131.20 (a) which in part states: “… Any water body segment with water quality standards that do not include the uses specified in section 101(a)(2) of the (Clean Water) Act shall be re-examined every three years to determine if any new information has become available.”

This review includes all listed modified Class 2 and Class 7 Limited Resource Value Waters (LRVWs) (Minn. R. 7050.0470).

MPCA is interested in the public’s comments regarding the need for updates and revisions to modified Class 2 and Class 7 waters as listed in Minn. R. 7050.0470.
