Description: Indicates that the facility does not inject the toxic chemical into a Class II-IV Underground Injection Well onsite. Class II wells are oil and gas related wells which re-inject produced fluids for disposal, enhanced recovery of oil, or hydrocarbon storage. Class III wells are those wells associated with the solution mining of minerals. Class IV wells are those wells which may inject hazardous or radioactive fluids directly or indirectly into USDW, only if injection is part of an authorized CERCLA/RCRA clean up operation. Class V wells, which include all types of injection wells which do not fall under I-IV, may inject only if they do not endanger USDW, public health or the environment. Class V wells are, generally, shallow drainage wells, such as floor drains connected to dry wells or drain fields. Values: 1 = 'Yes', 0 = 'No'.
