Class V Sensitivity

Metadata Updated: April 9, 2015

The c5sens.shp file shows areas where Class 5 automotive waste disposal wells are likely to present a threat to underground sources of drinking water based on geological conditions. The term "Class 5" refers to a broad category of disposal wells defined under federal regulations. Structures such as the drain fields for septic systems, dry wells, and underground gravel pockets that dispose of fluids used by internal combustion engines are identified as automotive waste disposal wells. Fluids include hydraulic fluid, antifreeze, grease, oil, gasoline, diesel fuel, brake fluid, and transmission fluid. The construction of new Class 5 automotive fluid waste disposal wells is not allowed under either federal or state regulations. Existing wells are not allowed in 1) the wellhead protection areas for public water supply wells or in 2) other sensitive areas. The Minnesota Department of Health is the lead agency for protecting public health and administers state and federal regulations that affect the wellhead protection program. The United States Environmental Protection Agency is responsible for administering federal underground injection control regulations in Minnesota. Together, the two agencies have developed a protocol for assessing where Class 5 automotive waste disposal wells present a threat to underground sources of drinking water. A copy of the document called Methodology for Mapping Areas Not Sensitive to Class 5 Automotive Waste Disposal Wells can be obtained from either the Minnesota Department of Health or the United States Environmental Protection Agency. It defines the subsurface geological conditions that must be present in order to reduce the potential risk that a Class 5 automotive waste disposal well presents to underground to prepare a sensitivity map and includes 1) site-specific data such as drilling logs or records of bedrock outcroppings and 2) interpretations of geologic conditions obtained from geologic maps and reports.
