inspection, hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or other systems of
<br /> non-destructive testing.You must keep comparison records and you must also inspect the container's supports and
<br /> foundations. In addition, you must frequently inspect the outside of the container for signs of deterioration, discharges,
<br /> or accumulation of oil inside diked areas. Records of inspections and tests kept under usual and customary business
<br /> practices satisfy the recordkeeping requirements of this paragraph.
<br /> (7)Control leakage through defective internal heating coils by monitoring the steam return and exhaust lines for
<br /> contamination from internal heating coils that discharge into an open watercourse, or pass the steam return or exhaust
<br /> lines through a settling tank, skimmer, or other separation or retention system.
<br /> (8) Engineer or update each container installation in accordance with good engineering practice to avoid discharges.
<br /> You must provide at least one of the following devices:
<br /> (i) High liquid level alarms with an audible or visual signal at a constantly attended operation or surveillance station. In
<br /> smaller facilities an audible air vent may suffice.
<br /> (ii) High liquid level pump cutoff devices set to stop flow at a predetermined container content level.
<br /> (iii) Direct audible or code signal communication between the container gauger and the pumping station.
<br /> (iv)A fast response system for determining the liquid level of each bulk storage container such as digital computers,
<br /> telepulse, or direct vision gauges. If you use this alternative, a person must be present to monitor gauges and the
<br /> overall filling of bulk storage containers.
<br /> (v)You must regularly test liquid level sensing devices to ensure proper operation.
<br /> (9)Observe effluent treatment facilities frequently enough to detect possible system upsets that could cause a
<br /> discharge as described in §112.1(b).
<br /> (10)Promptly correct visible discharges which result in a loss of oil from the container, including but not limited to
<br /> seams, gaskets, piping, pumps,valves, rivets, and bolts.You must promptly remove any accumulations of oil in diked
<br /> areas.
<br /> (11)Position or locate mobile or portable oil storage containers to prevent a discharge as described in §112.1(b).
<br /> Except for mobile refuelers and other non-transportation-related tank trucks, you must furnish a secondary means of
<br /> containment, such as a dike or catchment basin, sufficient to contain the capacity of the largest single compartment or
<br /> container with sufficient freeboard to contain precipitation.
<br /> (d)Facility transfer operations,pumping, and facility process. (1) Provide buried piping that is installed or replaced on
<br /> or after August 16, 2002,with a protective wrapping and coating. You must also cathodically protect such buried piping
<br /> installations or otherwise satisfy the corrosion protection standards for piping in part 280 of this chapter or a State
<br /> program approved under part 281 of this chapter. If a section of buried line is exposed for any reason, you must
<br /> carefully inspect it for deterioration. If you find corrosion damage, you must undertake additional examination and
<br /> corrective action as indicated by the magnitude of the damage.
<br /> (2)Cap or blank-flange the terminal connection at the transfer point and mark it as to origin when piping is not in
<br /> service or is in standby service for an extended time.
<br /> (3) Properly design pipe supports to minimize abrasion and corrosion and allow for expansion and contraction.
<br /> (4) Regularly inspect all aboveground valves, piping, and appurtenances. During the inspection you must assess the
<br /> general condition of items, such as flange joints, expansion joints, valve glands and bodies, catch pans, pipeline
<br /> supports, locking of valves, and metal surfaces. You must also conduct integrity and leak testing of buried piping at the
<br /> time of installation, modification, construction, relocation, or replacement.
<br /> (5)Warn all vehicles entering the facility to be sure that no vehicle will endanger aboveground piping or other oil
<br /> transfer operations.
