Box 633 Delano, Minnesota 55328 Dear Mr. Stevens, Mr. Moe, and Mr. Hirsch: Subject: Request for a Variance From Minnesota Rules, Chapter 4725 on the Wyatt Moe Property, 1230 Spruce Place, Orono, Township 117 North, Range 23 West, Section 8, Hennepin Count�Minnesota This letter is in response to your request for a variance from Minnesota Rules, Chapter 4725 to construct a we1138 feet from a floor drain located in the basement of the neighboring property at 1220 Spruce Place, Orono Minnesota. Minnesota Rules, part 4725.4450 requires that a well be located at least 50 feet from a buried sewer line or at least 20 feet from a buried sewer line constructed of cast-iron or approved plastic pipe with air-tested, watertight joints. Mr. James Stevens, well inspector with the Minnesota Department of Health (MDH), inspected the site on October 24, 1997. Mr. Stevens' inspection indicates that there is no location on the property that satisfies all of the required isolation distances. Based on the information submitted with the variance request, the site inspection by Mr. Stevens, and in accordance with Minnesota Rules, Chapter 4725, the variance is granted. The variance is granted because there is no location in the house on the above-mentioned property where it is feasible to place the sewer line and which satisfies all other required isolation distances. The proposed location, 38 feet north of the existing sewer, provides the most feasible separation between the existing floor drain and the proposed new well. Records of wells in the area, including wells on Spruce Street, indicate the presence of a clay confining layer extending from the surface to a depth of at least 60 feet. The presence of the confining layer and the requirement to grout through the confining layer should provide additional protection for the well.
