For scoping EAWs, written com- ments should address the accuracy and completeness of the information and suggest issues for investigation in the EiS. Such comments must be submitted to the Responsible Government Unit (RGU) during the 30 -day period following notice of the EAW's availability in the EQB Monitor. Contact the EQB (metro: 612/296-8253; non -metro: 1-800-652-9747, ask for envi- ronmental review program) or the RGU to find out when the 30 -day comment period ends. 1.

(Figures 4-8) 5e Describe'the proposed project completely (attach additional sheets as necessarv). The project consists of a 209 unit single family detached housing development. Utility service to this area was identified in an earlier EAW, (published 5/19/86), prepared by the MnPCA on the trunk sewer system in Section 31, Township 115, Range 19, Dakota County, Minnesota. That EAW described the phases of trunk sewer construction and the ultimate development of (1,920 housing units) Section 31. Wensmann Additions will be served ultimately by the trunk sewer system identified. The 209 unit Wensmann Additions has been designed to be constructed in two phases with phase 1 to be served by the Rosemount WWTP and phase 2 to be served by the Empire WWTP. 94 lots will be served to the east through the O'Leary's Hills and Wind's Crossing develop- ments to the Rosemount WWTP. The remaining 126 units would be served through West Ridge Additions to the south in 1989 or when the Empire WWTP has been expanded. 1 + 6e Reason for EAW preparation: eFit r RK -9 8 13 List all mandatory category rule #'s which apply: 6 KAK 5 J.

Elevated concentrations of nitrates have been reported in bedrock wells in the vicinity. However, a minimum of 145 feet of unconsolidated material is covering the bedrock and these sinks are not active. Present drainage to these basins is from agricultural land which tends to carry a higher nitrate load than does residential runoff. Therefore, the development of this section may result in a reduction of nitrate infiltration to the bedrock aquifer. 22. a.l This project will utilize 23.2 acre feet of permanent ponding for surface and storm water runoff. The quality of runoff should improve due to the reduction in concentrations of pesticides, herbicides and fertilizer as land is removed from agricultural production. a.2 207 homes @ 3 persons/ household and a maximum of 300 gallons/ household equals 62,700 gallons/day. 23. b. & c. Dust and noise will be limited to levels normally associated with subdivision construction. Both conditions are temporary; and, because of phasing, are expected to be short in duration (one to three months) in any given phase. Dust may be suppressed by watering, by limiting the amount of exposed soil and use of the erosion control measures described in Item 21. Noise can be limited by use of properly muffled equipment and limiting construction to daytime hours. 27. Construction of this subdivision and contiguous acreage in Section 31 will result in the loss of prime farmland. Section 31 is in an area well suited for planned extensions of urban development, both locally and regionally. Efforts to protect other areas with prime farmlands are being implemented by the City. 28. At ultimate development (1,920 homes), Section 31 could generate 19,000 ADT. Vehicle trips will be well distributed to existing and planned collector streets and minor arterial highways. It is estimated that the ADT on CSAH 42, west of Section 31, will be 5,100. The ADT on CSAH 42, east of Section 31, will be 4,900. The ADT on TH 3 (east of Section 31), north of CSAH 42, will be 2,800. Maximum ADT on 160th Street, in either direction, will be 2,000. Maximum ADT on Chippendale Avenue, at any point, will be 6,000. ADT on either Chippendale Avenue or Shannon Parkway (north -south collectors proposed at center section), north of CSAR 42, is 2,400.
