C. :\1innesota Environmental Quality Board (EQB) I. The EQB reminds the City of the closure of the 30-day comment period and details the pro.:.:s:. the City must follow in determining whither or not an EIS is required for the project. Rt!sponse: The City of Rosevilk wiri follo\\ all requirements and regulations as stipulated III Minnesota Rules part 44 r 0.1700. D. Minnesota Historical Societ). (MHS) [. The MHS concurred with the EA \\. statement that there are no properties listed on the National Register of Historic Places, and no known or suspected archaeological properties in the area that wil! be affected by this project.

Response: The type and amount of wastewater generated from the site is expected to be similar to the type and amount of wastewater produced by buildings currently located in the site. The propos~d improvements include the reconstruction of 30 parcels which wI!! result in additional totaf building square footage. The total amount of wastewater now generated from full development is expected to increas~ b;. approximately 84,347 gpd. This increase is based on a ma..\;,imum net increase of office/showroom square footage of 738,8 I 0 square feet. The additional peak wastewater flow anticipated in th<::: interceptor sewer is approximately 0.5 cubic feet per second. 3. MPGA requests infonnation demonstrating that the projected wastewater flows from the project area plus all adjacent contributing areas will not exceed the design of receiving sewers. Response: The existing sanitary sewer capacities have been calculated on the east and west ends of the project area to detennine the available capacity of the existing system. The calculated capacity of the interceptor pipe entering the project area is approximately 24.2 cfs while the pipe exiting the project area has a capacity of 31. 9 cfs. The flow differential of 7.7 cfs equates to availab Ie pipe capacity through the project area. The total amount of sanitary sewerage estimated to enter the system between the entrance and exit points is approximately 4.0 cfs to 6.5 cfs during peak flow conditions. The estimated available capacity is approximately 1.2 cfs greater than the estimated 30.7 cfs of total flow anticipated, therefore, the existing system should be adequate for the proposed development. 3
