Current through Register Vol. 48, No. 28, July 12, 2024
a) For
				tank removals, the following requirements and procedures shall be followed:
1) Compliance with subsections (a)(2) through
				(a)(18) is the responsibility of the licensed contractor.
2) Except as otherwise provided in this
				Section, the procedures of API 1604, incorporated by reference in 41 Ill. Adm.
				Code 174.210, shall be followed for
				vapor freeing and inerting procedures.
3) Secure proper permitting and schedule
				removal date with OSFM. A new permit and fee will be required when there is a
				failure to meet the Date Certain schedule established under Section
				175.320, including not showing
				for the inspection, not being completely ready for the inspection, allowing the
				permit to expire before the inspection, or not cancelling the job before 6:00
				a.m. the morning of the scheduled activity. (See Section
				175.300 for additional permit
				requirements.)
4) Maintain all
				combustible gas indicator equipment according to manufacturer's
				specifications.
5) Establish an
				exclusion zone within which smoking is prohibited, which shall include all
				hazardous (classified) locations/areas where work related to removal is being
				conducted. The use of spark producing/non-explosion proof equipment is
				prohibited in the vapor hazard area prior to removal of product and sludges and
				attaining the lower explosive limit (LEL)/oxygen levels required in subsection
				(a)(9).
6) Excavate to the top of
				the tank. Drain product from piping into the tank or into approved drums, being
				careful to avoid any spillage to the excavation area. Safely disconnect product
				piping from the tank. Further excavation below the top of the tank is not
				allowed until STSS has verified that tank conditions meet the LEL/oxygen
				criteria of subsection (a)(9).
7)
				Remove all liquids from the tank using explosion-proof pumps or hand pumps.
				When suctioning product out of tanks, plastic pipes shall not be allowed as a
				suction tube.
8) Regularly monitor
				the tank atmosphere and the excavation area with a combustible gas indicator
				for flammable or combustible vapor concentration until the tank is removed from
				both the excavation and the site. Monitoring the UST shall be done at 3 levels
				in the tank: top, middle and bottom. A confined space entry permit shall be
				obtained prior to tank entry and Safety Data Sheets (SDS) must be on
				site.
9) Regularly monitor the tank
				to insure explosive conditions do not exist. A maximum of 5% of the LEL, or 5%
				or less oxygen concentration, shall be attained before the tank is considered
				safe for removal, instead of 10%, as required in the API 1604. Dry ice shall
				not be allowed as a method of inerting tanks as referred to in API
				1604.
10) Bond all devices to the
				tank and ground the tank to a separate ground when vapor freeing the tank with
				compressed air or using inert gases under pressure. When using inert gases the
				cylinder shall be equipped with a pressure gauge, so that no more than 5 psi
				can be discharged into the tank during vapor freeing procedures. To ensure and
				maintain proper grounding and bonding, the connections shall be tested by the
				contractor for continuity. This testing shall be done with equipment designed
				for continuity testing. When vapor freeing of tanks, plastic pipes shall not be
				allowed as a vent tube on eductors.
11) Plug and cap all accessible tank holes.
				One plug should have an 1/8 inch vent hole.
12) Excavate around the tank to prepare for
				removal. This shall include excavation along one side and one end, from top to
				bottom.
13) A STSS shall be on site
				before any tanks and piping are removed.
14) With STSS on site, remove tank and piping
				from the ground. Equipment with sufficient lifting capacity shall be used to
				lift the tank from the excavation and must be rated as appropriate for the
				particular site and excavation.
15)
				Protective Equipment and Tank Cleaning Requirements
A) Cleaning procedures shall be in accordance
				with API 2015, incorporated by reference in 41 Ill. Adm. Code 174.210. Personal
				protection requirements for tank cleaning personnel shall, at a minimum,
				include the following:
i) protective
				respiratory equipment for tank cleaning personnel shall be the type that
				provides supplied positive air pressure to a full-face mask throughout the
				breathing cycle during all cleaning operations, in accordance with API
				2015;
ii) level B personal
				protective equipment with body harness and tag line;
iii) protective booties;
iv) continual monitoring of LEL and oxygen
				during cleaning; and
v)
				attendant/observer.
B)
				Requirements in subsection (a)(15)(A) shall not apply in the event that no
				physical entry is made into the tank.
16) Any UST removed from the excavation zone
				shall be properly cleaned on site the day of the removal and removed from the
				site within 24 hours.
17) Tanks
				larger than 2,000 gallons in capacity shall have holes or openings no less than
				3 feet x 3 feet, one on each end or side, for cleaning. Tanks less than 2,000
				gallons capacity shall have one entire side removed from end to end and shall
				be no less than 3 feet wide.
18)
				The use of spark producing/non-explosion proof equipment is prohibited in the
				vapor hazard area prior to attaining the LEL/oxygen levels required in
				subsection (a)(9).
19) If an STSS
				has observed evidence of a release, the owner, operator or designated
				representative of the UST owner/operator must notify the Illinois Emergency
				Management Agency. This is to be done at the site immediately following the
				field determination and the incident number shall be given to the STSS prior to
				his/her leaving the site.
20) All
				removals require a site assessment pursuant to 41 Ill. Adm. Code
				176.330.
21) Any tank being removed without an OSFM
				permit will be required to be put back in the excavation and vented to 12 feet
				above grade if it has not been removed from the site and covered with backfill
				until a permit and licensed contractor can remove it properly.
