' NWI has not been field verified for a portion of the Proposed Route off of Xcel Energy property, <br /> and sometimes contains inaccuracies. However, it is a good tool for initial wetland identification <br /> and assessment. <br /> Xcel Energy engaged Westwood Professional Services, Inc. ("Westwood") to perform a wetland <br /> delineation of the 16 acre Orono Substation site and prepared a Wetland Delineation Report (dated <br /> ' July.2,2010). The wetland area within the 16 acre site was identified as a type 3 Palustrine Emergent <br /> ("PEM") (Shallow Marsh) wetland. Additionally this wetland is classified as seasonally flooded, <br /> partially drained/ditched ("PEMCd"). The dominate vegetation within the wetland consisted of <br /> ' cattail and reed canary grass, with lesser amounts of Box Elder. The vegetation within the upland <br /> areas of the site transitioned from hydrophytic vegetation in the wetland areas to non-hydrophytic <br /> vegetation in the upland areas. Westwood prepared the Wetland Delineation Report (dated July 2, <br /> ' 2010); Xcel Energy submitted the Wetland Delineation Report to the Minnehaha Creek Watershed <br /> District ("MCWD") on August 4, 2010; the MCWD issued a Notice of Application for the <br /> delineation and requested comments on August 10, 2010; and the MCWD issued a Notice of <br /> Decision accepting the wetland delineation on September 14, 2010. The Wetland Delineation <br /> Report can be found in Appendix F along with the Minnesota Wetland Conservation Act <br /> ("WCA'),Notice of Decision (dated September 14,2010) by the MWCD. <br /> In total, two wetlands were identified within the 400 foot wide route width for the proposed <br /> transmission line (see Appendix B-6). One additional wetland was identified just outside of the 400 <br /> foot wide route width. Overall,the 400 foot transmission line corridor extends approximately 3,136 <br /> ' feet and encompasses approximately 28.8 acres, of which approximately 13.63 acres (47%) are <br /> wetlands. Approximately 3.29 acres of the 75 foot right-of-way required for the transmission line <br /> are wetlands. Based upon preliminary structure locations and design spans nine transmission <br /> ' structures will be necessary for the proposed Project. It is estimated that five or six of these <br /> structures will fall within or on the edge of wetlands (see Appendix B-2 and B-6). <br /> ' The wetland present within the Proposed Route is classified as a Palustrine type wetland. Other <br /> wetlands near the Project site are also Palustrine type wetlands. The Palustrine System includes all <br /> nontidal wetlands dominated by trees, shrubs,emergents,mosses or lichens (Cowardin et al. 1979). <br /> Vegetation within the wetland crossed on the 16 acre Orono Substation site consists of emergent <br /> vegetation with a mixture of grasses, cattail, shrubs and herbaceous vegetation (see Wetland <br /> Delineation Report in Appendix F). The wetland present on the Orono Substation site is a large <br /> ' portion of PWI unnamed (27-916 W) crossed by the Project. The other PWI unnamed (27-917 W) <br /> crossed by the Project appears to have once been connected to unnamed (27-916 W) and likely will <br /> be of similar make up. Both of these wetlands are identified as public water wetlands (MnDNR <br /> ' 2010d). However, human impact in the form of residential development has since separated these <br /> two wetlands for construction of a road within the HFA. <br /> ' The proposed Project will have minor, mostly short term effects on surface water resources and <br /> associated wetlands. Most potential effects on surface waters and wetlands will be related to <br /> construction of the proposed transmission line across the existing wetlands. The Project may <br /> ' require wetland and water resource approvals from the U.S. Army Corps of Engineers ("USACE"), <br /> MnDNR,Hennepin County and the MWCD. USACE administers the federal Clean Water Act and <br /> Rivers and Harbors Act. A license from the MnDNR is required to cross public water wetlands. <br /> ' Orono Project June 7, 2011 <br /> MPUC Docket No. E002/TL-11-223 55 <br />
