Accepted Answer

Automatic line leak detector

Question 3

What is the minimum leak rate that a monthly automatic tank gauging test must be capable of detecting?

Accepted Answer

0.2 gallon per hour

Answer

EPA regulations require monthly ATG tests to detect leaks of 0.2 gallon per hour with a probability of detection of 95% and a probability of false alarm of 5%.

Question 4

A groundwater monitoring well used for UST release detection must be installed by a(n):

Accepted Answer

Licensed well driller or qualified professional

Answer

Groundwater monitoring wells must be installed by a licensed well driller or qualified professional to ensure proper placement and avoid cross-contamination.

Question 5

Which condition would cause an automatic line leak detector to trigger a 'restricted flow' response?
