The Monitoring Certification, Spill Containment Test, Line Leak Detection Test is a task in the Underground Storage Tank program.
Underground storage tanks (USTs) operated in California are subject to annual testing to verify that the leak detection system works as intended. This test is called the UST Monitoring System Certification. The exact tests required of a given UST system depends on when and how it was installed. The majority of tests
All tanks systems must complete a monitoring certification annually. In addition, this test must be witnessed by a Unified Program Agency inspector. The monitoring test verifies the sensors and monitoring panel are functioning as designed. During the test a technician will use water to trigger alarm sensors, check the fuel probe to verify it signals an overfill at the right height, and check that the system operates as intended in the event of a power failure.
