Where underground piping is connected to an AST, the definition of “secondary containment” for UST systems also applies to the piping. For UST systems secondary containment is a release prevention and release detection system for an underground tank and/or piping. The release prevention part of secondary containment is an underground tank and/or piping having an inner and outer barrier. Between these two barriers is a space for monitoring. The release detection part of secondary containment is a method of monitoring the space between the inner and outer barriers for a leak or release of regulated substances from the underground tank and/or piping (called interstitial monitoring). This term includes containment sumps when used for interstitial monitoring of piping. “Secondary containment tank” is a shop-fabricated AST that includes a steel or reinforced concrete secondary shell that will provide containment of the entire capacity of the inner tank in case of leaks or ruptures of the inner tank and having means for monitoring the interstitial space for a leak.

CODE OF COLORADO REGULATIONS 7 CCR 1101-14 Division of Oil and Public Safety 25 (a) Tanks. Secondary containment and interstitial monitoring is required for all new underground tank installations. Secondary containment must be able to contain regulated substances leaked from the primary containment until they are detected and removed and prevent the release of regulated substances to the environment at any time during the operational life of the UST system. If an existing underground tank is replaced, the secondary containment and interstitial monitoring requirements apply only to the replaced underground tank. The secondary containment requirements do not apply to repairs meant to restore an underground tank to operating condition revent the release of regulated substances to the environment at any time during the operational life of the UST system.

Installation of new or replaced piping will require the installation of containment sumps (under- dispenser [UDC], submersible turbine pump [STP] or transition) on both ends of the secondarily contained pipe for interstitial monitoring. These secondary containment requirements do not apply to repairs meant to restore piping to operating condition. For the purposes of determining when secondary containment is required by these rules, a repair is any activity that does not meet the definition of “replace”. These secondary containment requirements also do not apply to vent piping, vapor recovery piping, and fill pipes not connected to remote fills containment requirements do not apply to repairs meant to restore piping to operating condition. For the purposes of determining when secondary containment is required by these rules, a repair is any activity that does not meet the definition of “replace”.
