4. Number of parking stalls, existing and additional <br />Designated parking spaces and undesignated space are available within the campus for the plant <br />operators, as well as contracted construction and maintenance personnel. Given that no more than two <br />new permanent staff might be added, Great River Energy does not intend to add additional parking <br />spaces specifically for the new combustion turbine operation. <br />(Independent of the proposed project, Great River Energy is considering utilizing a portion of the current <br />paved area on the south side of the ERERS for additional/overflow parking of business -related vehicles. <br />The size/number of stalls is yet to be determine and is planned to be addressed as part of the site <br />restoration when demolition is complete. The conceptual parking area is shown in Figure 4.) <br />S. Is there proposed screening of the site? <br />If the proposed unit were to be installed east of the existing 200 MW combustion turbine, existing trees <br />along the west side of Highway 169 provide an effective screen. The current fence along this side of the <br />facility also has a privacy screen. <br />If the proposed unit were to be installed within the existing RDF Barn, the building would provide <br />effective screening. <br />6. Proposed building materials <br />6.1. How do they comply with applicable design standards? <br />The combustion turbine is comprised of modular or semi -modular components that would be brought <br />on site and assembled together. Great River Energy is currently exploring weatherization issues with the <br />equipment vendor. If enclosures are necessary for either project location, materials would be <br />compatible for Elk River's meteorological conditions and any local building codes. <br />7. Signage — (at time of installation, a separate permit is required for each sign) <br />We do not anticipate any changes to existing signage for the proposed combustion turbine. <br />7.1. How many? Not Applicable <br />7.2. Proposed sizes? Not Applicable <br />7.3. Locations? Not Applicable <br />7.4. What type? Not Applicable <br />8. Is there outdoor storage? <br />As noted, the existing backup fuel oil storage tank will be sufficient to supply the proposed and existing <br />combustion turbines. Accordingly, the proposed project is not expected to involve any additional <br />permanent outdoor storage. During construction, materials and project components may be temporarily <br />stored in close proximity to the final project site and/or within the existing RDF building. <br />(Within the existing campus footprint, multiple outdoor storage areas are present. Independent of the <br />proposed project, and part of the site restoration following demolition of the ERERS, Great River Energy <br />is intending to relocate one of these existing storage yards to the former ERERS footprint area as shown <br />in Figure 4.) <br />Project Narrative <br />Great River Energy — Proposed Combustion Turbine Addition <br />
