EPA has developed draft Underground Injection Control (UIC) Class II permitting guidance for oil and gas hydraulic fracturing activities using diesel fuels. This document describes information useful in permitting the underground injection of oil- and gas-related hydraulic fracturing using diesel fuels where EPA is the permitting authority. EPA’s goal is to improve compliance with the Safe Drinking Water Act (SDWA) requirements and strengthen environmental protections consistent with existing law.
