A.
Facility Lockout.
When a facility is not in use or under competent
				supervision for a period of 7 consecutive days or longer, the gates and other
				access ways must be closed and locked, and the loading valves, filling and
				gauging pipes must be locked. All tanks, piping, equipment and other devices
				must be capped or blanked in a manner to prevent their use. Valves that isolate
				tanks, piping and equipment or that could permit a discharge must be locked in
				the closed position. Any dedicated electrical or hydraulic control devices
				serving the tank, piping or other equipment must be locked in the closed
				position. The owner or operator shall notify the Department at least 10 days
				prior to a facility lockout.
B.
Temporarily Out of Service.
Facility owners or operators shall
				notify the Department of storage tanks or facilities that are planned to be or
				have been temporarily out of service for 12 or more months. The storage tanks
				or facility must be temporarily closed as follows:
(1) All oil must be removed from the tank and
				piping system to the lowest drawoff point. Any waste oil generated from the
				tank or piping must be disposed of in accordance with all applicable state and
				federal requirements;
(2) Tanks
				must be protected from flotation in accordance with good engineering practices
				if in an area within four feet above the 100-year floodplain;
(3) All openings must be secured and locked.
				Fill pipes, downloading pipes and any other pipes and openings must be capped
				or secured to prevent access, or accidental or unauthorized use or
				tampering;
(4) Storage tanks or
				facilities that are temporarily out of service are subject to all requirements
				of this Chapter including, but not limited to, periodic testing, inspection,
				licensing and reporting requirements;
(5) Tanks or piping that are temporarily out
				of service for more than 2 years must be cleaned, and certified to be gas free
				by a marine chemist or a certified industrial hygienist. Oil and oil residue
				must be removed from the tank and all connecting pipes. Connecting pipes must
				be disconnected or blanked to ensure product is not able to be inadvertently
				transferred into the closed tanks or piping:
(6) A tank that has been temporarily out of
				service may not be reactivated for petroleum storage unless a suitability for
				service inspection is performed that finds the tank suitable for its intended
				service in accordance with
API 653
. Suitability for service
				inspections may only be conducted by a qualified engineer with expertise in the
				construction and design of field constructed aboveground storage tanks and who
				is a State of Maine licensed professional engineer or an engineer otherwise
				working in compliance with Maine's professional regulation statutes. A report
				detailing the results of the inspection must be provided to the Department that
				is signed and sealed by the professional engineer conducting the
				inspection.
