Current through Supplement No. 395, January, 2025
1. Secondary containment for tanks must include one or more of the following:
a. A liner (external to the tank).
b. A double-walled tank.
c. An equivalent device (documentation of
equivalency must be maintained at the facility).
2. External liner systems must be:
a. Designed or operated to contain one
hundred percent of the capacity of the largest tank within its
boundary.
b. Designed or operated
to prevent run-on or infiltration of precipitation into the secondary
containment system unless the collection system has sufficient excess capacity
to contain run-on or infiltration. The additional capacity must be sufficient
to contain precipitation from a twenty-five-year, twenty-four-hour rainfall
event.
c. Free of cracks or
gaps.
d. Designed and installed to
surround the tank completely and to cover all surrounding earth likely to come
into contact with the waste if the waste is released from the tanks (capable of
preventing lateral as well as vertical migration of the waste).
3. Double-walled tanks must be:
a. Designed as an integral structure (an
inner tank completely enveloped within an outer shell) so that any release from
the inner tank is contained by the outer shell.
b. Protected, if constructed of metal, from
both corrosion of the primary tank interior and of the external surface of the
outer shell.
c. Provided with a
built-in continuous leak detection system capable of detecting a release within
twenty-four hours.
