Rob Carlson Rob Carlson Builders, Inc. 1680 99th Lane Northeast Blaine, Minnesota 55449 Dear Mr. Carlson: Subject: Abandoned, Unsealed, 2- Inch - Diameter Water - Supply Well at 3250 Twin Lake Boulevard Little Canada, Ramsey County, Minnesota This letter is written to inform you of the presence of an unsealed, abandoned, 2- inch - diameter well on your property at 3250 Twin Lake Boulevard, Little Canada, Minnesota. A 2 -inch- diameter well, approximately 105 feet deep, served the property until the 1960s when the well failed. During an attempt to repair the well, drill tools became stuck in the well and could not be removed_ A 137- foot -deep, 4- inch - diameter water- supply well was constructed in the same well pit, directly adjacent to the 2- inch - diameter well, in au attempt to loosen the 2 -inch well so that it could be pulled out to retrieve the lost drilling tools. During the attempt to pull out the 2 -inch well, the 2 -inch well casing broke off between 20 and 40 feet below the surface. The tools .lost in the 2 -inch well included 42 feet of 1- inch - diameter extra heavy pipe and a 3 -foot string of tools, which included a taper tap and drilling jars. In May of 2003, the 4- inch - diameter well was sealed by Johnson Brothers Well Drilling Company. In addition, Ray Anderson Excavating Company attempted to uncover the 2 -inch well with a track -hoe excavator so that it also could be sealed. A hole was excavated to a depth of approximately 12 feet below the surface; however, the 2 -inch well was not located. Minnesota rules governing well sealing require that debris, obstructions, or other materials that could interfere with sealing be removed from a well prior to sealing. Once a well is cleared of obstructions, a grout pipe must be inserted to the bottom of the well and a cement or bentonite grout must be pumped into the well until it is full. We understand that you wish to develop the property and build several homes on it. Lf the well is not located and properly sealed by a licensed well contactor, you must apply to the Minnesota Department of Health for a variance to postpone permanent sealing of the well until it can be accessed and sealed. The variance must be recorded with the deed for the property at the county General Information: (651) 215 -5800 a TDD /TTY: (651) 215.8980 • Minnesota .Relay Service.
