Today, the Environmental Protection Agency (EPA) is announcing a final determination for all sub-classes of Class V injection wells not included in the final rulemaking on Class V motor vehicle waste disposal wells and large-capacity cesspools (December 7, 1999). These include shallow non-hazardous industrial waste disposal wells, large- capacity septic systems, agricultural and storm water drainage wells, and other wells. The Agency has determined that the existing Federal underground injection control (UIC) regulations are adequate to prevent these Class V wells from endangering underground sources of drinking water (USDWs) and no new rulemaking is necessary at this time. Because today's action fulfills the Agency's obligation with regard to Class V wells as stated in section 1421 of the Safe Drinking Water Act, EPA is also amending its UIC rules by removing outdated references regarding future Class V regulations. In addition, some minor changes were made to correct mistakes and omissions within the CFR.
