Exemption 8420.0420 Subp. 6(A) Solar panels will be installed within the delineated boundary of wetlands 1 and 2 on a rack system that utilizes driven posts to support the panel. The applicant is requesting an exemption for the installation of the panel posts based on MN Rule 8420.0420 Subp. 6(A). The applicant has demonstrated that the project has avoided and minimized wetland impacts to the greatest extent possible and that less than'/2 acre of wetlands will be impacted. No -loss 8420.0415 Subp.(A) and MN Rule 8420.0415 Subp. H Fence posts will be installed within the delineated boundaries of wetlands 1 and 2. The applicant is requesting a no -loss under the criteria of MN Rule 8420.0415 Subp.(A) as is supported by MN Rule 8420.0111 Subps. 26 and 32. The applicant is also requesting a no -loss under MN Rule 8420.0415 Subp. H for temporary impacts associated with ground disturbing activities from heavy equipment. This project, as proposed, will satisfy the requirements for no -loss under the MN Rule 8420 sections and subparts referenced above. The application for sequencing, no -loss, exemption, and replacement for permanent wetland impacts is approved with the following conditions to protect the high quality vegetative community, reduce permanent impacts to on -site wetlands, and reduce the loss in the quantity, quality, and biological diversity of on -site wetlands. Conditions: 1.) The layout area (shown in the site plan provided with the application and dated 10-10-18) and delineated wetland boundaries will be clearly marked and communicated to contractors to avoid heavy equipment operation in any wetland areas outside of the proposed array. 2.) Grading will be minimized to only areas needed to install footings or posts in high quality wetland; no mass grading. 3.) Ground disturbing activities only to be completed during dormant period (October -March) and when frost is present at a depth sufficient to minimize soil compaction. Frozen ground conditions may be enhanced or created by clearing snow from the construction corridors by plowing. If frost is not present at a depth that will prevent compaction, the contractor will take precautions that may include the use of mats and/or tracked equipment. 4.) As described in the applicant's permit request, disturbed areas will be restored using a native seed mix. The seed mix shall be a custom mix that is limited to and includes high quality native species that are currently found on site. 5.) Panels will be installed no higher than the maximum height as allowed by Hugo City ordinance, but the distance between the ground elevation and the panel should be maximized to reduce shading of ground vegetation. 6.) The LGU will be allowed access to the site to inspect the facility and complete vegetation monitoring surveys to assess changes in the vegetative community as needed during the 25-year lifespan of the project. 7.) Future maintenance activities may require no -loss approval. BWSR Forms 11-25-09 Page 3 of 4
