NR 851.52(7) (7) The diversion will result in no significant adverse individual impacts or cumulative impacts to the quantity or quality of the waters of the Great Lakes basin or to water-dependent natural resources, including cumulative impacts that might result due to any precedent-setting aspects of the proposed diversion, based upon a determination that the proposed diversion does not have any significant adverse impacts on the sustainable management of the waters of the Great Lakes basin.

NR 851.52(8) (8) The applicant has a Tier 3 water conservation plan developed in compliance with ch. NR 852 and commits to implementing the water conservation plan.
