2. For cathodically protected tanks and integral piping, secondary containment systems shall not interfere with the operation of the cathodic protection system.
3. Secondary containment systems shall be designed and installed to direct any release to a monitoring point or points.
4. If factory-made single-walled spill containment systems or single-walled sumps are installed on the system, a containment integrity test shall be performed before the component is placed into service in accordance with the manufacturer’s testing requirements. For system components without manufacturer containment integrity testing specifications, PEI/RP1200-19, 2019 Edition shall be used.
