Which organization’s testing requirements does the pressure decay and dynamic back pressure testing meet according to the PEI 300 manual?

The correct answer is associated with the California Air Resources Board (CARB), which is known for its stringent regulations and testing requirements related to air quality and emissions. The pressure decay and dynamic back pressure testing methods outlined in the PEI 300 manual are designed to ensure that vapor recovery systems are functioning properly and are not leaking harmful vapors into the environment.

CARB has specific standards that must be met to minimize emissions from gasoline dispensing systems, and the testing methods mentioned are integral to assessing compliance with these standards. This ties directly into CARB's mission of reducing air pollution in California and is relevant for facilities operating vapor recovery systems within that jurisdiction.

While OSHA focuses on workplace safety and health standards, and the EPA regulates environmental protection at the federal level, the specific context in which pressure decay and dynamic back pressure testing is relevant is CARB's target on air quality and vapor recovery efficiency. Therefore, the alignment with CARB's requirements makes this the appropriate answer. PEI, being an organization that develops guidelines, provides information but does not set enforcement testing requirements like CARB does.
