The standards and guidelines in this part shall be used in �+etland creation and , restoration efforts to ensure adequate replacement of wetland functions and values. , In evaluating a Wetland replacement plan, the local `government unit must determine whether the Wetland type stated ' as the replacement plan goal will result from the replacement plan specifications. If a Wetland type other than the - replacement plan goal is likely to result, the locel government unit must evaluate the plan basea on this dete=mination. The ' local government unit must also determine thnt the proposed replacement plan will adequately =eplace functions and public values lost. If adequate replacement of function ana public , value is not likely to result, the local government must determine ahat further measures are necessary to obtnin afiequate� replacenent or deny the replacement plan. ' Subp. 2. Specific requiretents. The stnndttrds in itens A • to 8 shall be folloWed in all wetland replaceaents unless the . technicnl evaluation panel deteruines that a standard is clearly not dpproprinte. ' A. Hater cvnttol structures must be aanstructed uBing specifications provided in the Minnesota Hetland Restoration Guide or their equivalent. Control structuzes may be subject to , the Department of Nntural Resources dnn safetp reguldtiofls. B. Best manage�►ent practices must be established and maintained adjacent to the entire pe=iaeter of all replacea�ent Wetlands. ' C. For replacement vetlande vrhere native, noninvasive vegetation that is cha=acteristic of the r+etland type identified ae the =eplacenent goal in part 8420.0530, item D, is not likelp to become domina�nt naturally in a five-year period, th� � replacenent Wetlnnd shall be seeded or planted with appropLiate nntive, noninvasive species, as determined by the technical evrsluation panel. If the replacement wetland is seeded or � planted, the seed or planting stock st�ould be froa native, i�vuliivaeii�c OlIC�.aCO 'v: �a.y�:.:..� ::^�-��`r ^=�.^y�^_ T��rinu the nonitoring period, the applicant must take reasonable steps to contro� invasion by any nonnative or 3nvasive species, for ' exaiaple., reed canary gra►ss, Canada thietle, comnon buckthocn, spotted knapweed, leafy apurge, purple loosestrife, and Eurasian wdter silfoil, that would defeat the revegetation goal of the , replace4ent plan. D. Erosfon cont=ol measures as deternined by the soil and water coaserv�tion district must be enployed during construction end until per�anent ground cover is estnblished to , ' prevent siltation of the replacement wetlnnd or nearbp water i bodies. � E. For all restored wetlands Where the orfginal ' � o=gnnic substrate has been stripped away and for all cteated Wetlands, proviaione must be mz�de for providing an organic ! substrate unless ttie technical evaluation panel recommends i othe=Wfse. fihen feasible, the orga�nic soil used for backfill ' should be taken from the drained or filled wetland domineted bg native, noninvaeive species. Organic soil for backfill from Wetlands domindted by nonnative, invasive species should be ' avoided. F. The bottom contours of created types� 3, 4, and 5 wetlands should be undulating, rather than flat, to provide a variety of vater depths, compa►rable to natural Wetlands in the � vicinity of Ehe replacement, and be consist-ent With part 8l20.0547, subpart 2.
