C. Minnesota Environmental Quality Board (EQB) 1. The EQB reminds the City of the closure of the 30-day comment period and details the process the City must follow in determining whether or not an EIS is required for the project. Response: The City of Roseville will follow all requirements and regulations as stipulated In Minnesota Rules part 4410.1700. D. Minnesota Historical Society (MHS) 1. The MHS concurred with the EA W 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 will be affected by this project. E. Minnesota Pollution Control Agency (MPCA) I. MPCA requests information for the runoff analysis for a two-year event in addition to the ten year and 100 year events documented in the EA W. Response: The proposed project would reduce storm water runoff over the 126 acres of development parcels and public roadway areas by 1.56 acre-feet from 26.20 acre-feet to 24,64 acre-feet during a 2 year, 24 hour event. 2, MPCA requests a description of how wastewater flow is expected to change compared to previous uses in the project area. 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 proposed improvements include the reconstruction 000 parcels which will result in additional total building square footage. The total amount of wastewater flow generated from full development is expected to increase by approximately 84,347 gpd, This increase is based on a maximum net increase of office/showroom square footage of 738,810 square feet. The additional peak wastewater flow anticipated in the interceptor sewer is approximately 0,5 cubic feet per second, 3. MPCA requests information 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 determine 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 available 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
