Z IN E S O T A MENToFHEAITH Protecting, maintaining and improving the health of all Minnesotans May 22, 2003 Refer to: License Number 27172 (TN 2921) Mr. Mark Stodola Mr. Bob Pieper Don Stodola Well Drilling Company, Inc. 4753 North Shore Drive 3841 North Main Street Orono, Minnesota 55364 St. Bonifacius, Minnesota 55375 Dear Mr. Stodola and Mr. Pieper: Subject: Request for a Variance from Minnesota Rules, Chapter 4725, to Construct a Water-Supply Well, Minnesota Unique Well Number 688985, on the Bob Pieper Property at 4753 North Shore Drive, Orono, Located in Township 117 North,. Range 23 West, Section 7, Hennepin County, Minnesota This letter is in response to your request for a variance from Minnesota Rules, Chapter 4725, to construct the subject water-supply well 30 feet from an untested buried sewer located on the subject property. Minnesota Rules, part 4725.4450, subpart 1, item E (12) requires that a water-supply well must be located at least 50 feet from a buried sewer, including a collector or municipal sewer. Minnesota Rules, part 4725.4450, subpart 1, item F (5) does allow a well to be located a minimum of 20 feet from a buried sewer that is pressurized and serves one single-family residence or is a gravity sewer which is not a collector or municipal sewer, and that is constructed of cast-iron or plastic pipe that meets the materials and pressure testing specifications of Minnesota Rules, parts 4715.0530 and 4715.2820 (Minnesota Plumbing Code). Mr. Douglas Edson of the Minnesota Department of Health (MDH) St. Paul district office inspected the subject property on May 7, 2003, with Mr. Bob Pieper, and Mr. Rick Stodola of Don Stodola Well Co.. Mr. Pieper reported that a new home is planned for construction after the existing house is demolished. The existing well will be sealed since it is located where a new driveway is planned. Mr. Pieper indicated that the existing sewer extending north from the house to the city sewer main will be replaced, except for the portion under North Shore Drive. He added that the new sewers under the house will be constructed of approved materials and will be air tested. Mr. Edson reported that, because of the narrow lot, the existing municipal sewer under North Shore Drive and on neighboring properties, there is no accessible location on the subject property to construct a new well which would satisfy all isolation requirements of Minnesota Rules, Chapter 4725. Mr. Edson and Mr. Rick Stodola identified an accessible location which maximizes the isolation from known sources of contamination, located 30 feet from an untested buried sewer under North Shore Drive. The location is in excess of 50 feet from the municipal sewer under North Shore Drive.
