Water Quality Rule – Petroleum, Hazardous and Deleterious Materials Water Quality Standards (IDAPA ) defines release as: “Any unauthorized spilling, leaking, emitting, discharging, escaping, leaching or disposing into soil, groundwater, or surface water.”

Water Quality Rule – Petroleum IDAPA Water Quality Standards Requires clean up and reporting of used oil and petroleum releases by owners and operators Contain and immediately clean up an above ground spill only after mitigating any fire, explosion and vapor hazards. An above ground spill exceeding 25 gallons…shall be reported to DEQ within 24 hours and owners shall begin corrective action.  Note: a includes spills causing a sheen on surface water An above ground spill less than 25 gallons…shall be reported to DEQ only if cleanup cannot be accomplished within 24 hours.
