A sensitive well has less than 50 feet of watertight casing, and which is not cased below a confining layer or confining materials of at least 10' in thickness. These sources, known as Class V underground injection wells, are regulated by the federal U.S. Environmental Protection Agency. These sources are classified as illegal by Minnesota Rules, Chapter 4725. 4 Isolation distance is determined by average flow per day or if a facility handles infectious or pathological wastes. A community public water -supply well must be a minimum of 50 feet from a petroleum tank or container, unless the tank or container is used for emergency pumping and is located in a room or building separate from the community well; and is of double -wall construction with leak detection between walls; or is protected with secondary containment. This form is based on the new isolation distances in Minnesota Rules, Chapter 4725, related to wells and borings adopted August 4, 2008, and Minnesota Rules, Chapter 4720, related to wellhead protection. 6/21/2019 3
