Page 13 <br /> 6.4.5 EXHIBIT I/J - Soils and Vegetation Information <br /> A portion of in situ soils may be used in an over the shoulder method to resoil the completed <br /> banks of basin slopes or other upland areas in time. Commonly, soils will be parked in stockpiles <br /> until ready for application in a manner more fully described below. <br /> Consistent with existing zoned agricultural practices, soil from an adjacent wetland bank was <br /> approved by the City of Evans, and completed in early 2021. The City of Evans approved (refer to <br /> the Addendum at the back of this Exhibit) the placement of these soils within the floodplain of the <br /> upper North-East portion of Central Field, as shown on Exhibit C-2: Extraction Plan Map. These <br /> orphan soils are in place, seeded, and the area remains under continuing agricultural production, <br /> yet are no longer part of the area floodplain. The current extent of this 200,000± cu.yd. stockpile <br /> is represented on Exhibit L: Financial Warranty Map. This stockpile location area will also receive <br /> a portion of soils removed from planned extraction locations over other areas of Central and <br /> North-West Fields. It should be noted that a monoculture of cultivated corn occupies a majority of <br /> the planned areas of extraction, and will gradually be turned out of production through extraction. <br /> This soil may be utilized to line the resulting basins, for reclamation of affected lands above the <br /> static water level, or for market as warranted. <br /> 'As described in Exhibit D, wetland conditions appear confined within portions of the stream <br /> terrace and bank-full stage of the rivers, and along segments internal to the Evans Canal. <br /> Excavation and processing activities will not take place within these areas. <br /> Under Exhibit M is an approved U.S. Army Corps of Engineers report designating 'No Permit <br /> Req ui red.' <br /> If and when a conveyor is built upon the projected line, the footings are not expected to exceed <br /> the requirements for a Nationwide Permit, but if they will, a Nationwide Permit will be applied for <br /> and secured prior to affecting such areas. If a Nationwide Permit is necessary, the OMLR will be <br /> provided with the necessary justification or approval under an OMLR Technical Revision to that <br /> end. <br /> At this time there is little to find in dominant preferred species of cover typifying the cropped fields <br /> or riverine areas. Beyond the row crops, the former pasturelands appear impacted by overgrazing, <br /> monocultures of smooth brome, annuals, and other comparatively recent impacts. Reclamation <br /> will not return the former Fields to agricultural crop production. Further, present day impacts over <br /> the planned Processing and Wash Pond locations do not reflect representative or realistic percent <br /> cover of a desirable matrix of native vegetation communities intended for reclamation. <br /> Consequently, the reclamation target will be to establish a stabilizing foliar cover of predominantly <br /> native vegetation (refer to seed mixture) of approximately 20 percent [determined as measured at <br /> the stem three inches above the ground surface respective of the foliar diameter of the <br /> established grass species, as determined by ocular estimates, or utilizing standard vegetation <br /> cover analysis such as line transect, as warranted]. <br /> For clarity, topsoil is generally regarded as the plow layer (upper six inches) on agricultural soils, <br /> or the A-1 soil profile horizon otherwise. The solum, or soil, includes the topsoil plus all other <br /> material found above the regolith of the parent rock, and generally no deeper than the optimal <br /> 'Adequacy Item 49 <br /> VARRA COMPANIES, INC.
