Question: Do I still need to perform my annual PSIP compliance test now that the Clean Truck Check is being implemented?
Answer: Yes. The PSIP regulation is still in effect and vehicles subject to the regulation still must perform their annual opacity tests. PSIP will remain in effect until the Clean Truck Check periodic testing requirements take effect. Please note that if you happened to submit a passing compliance test to resolve an Notice to Submit to Testing as part of the Clean Truck Check, this test can be used to meet your PSIP requirements for the given calendar year.
Question: If I want to take advantage of the OBD submission option for PSIP compliance, when does the test need to be conducted and how frequent are the inspection requirements?
Answer: PSIP requires a compliance test once per calendar year. Regardless of whether you choose to continue your annual smoke opacity testing or submit an OBD test in lieu of this smoke opacity test, the timing and frequency of testing remain the same. Once you complete a passing vehicle test in a given calendar year, keep the record of the passing result, and you have met the requirements for PSIP.
Question: I am a PSIP smoke tester, but not a credentialed tester for the Clean Truck Check. What vehicle testing am I allowed to perform?
Answer: You may continue to perform smoke opacity testing using your current SAE J1667-compatible smoke meter for the PSIP regulation. You may also continue using your current PSIP smoke tester ID number for PSIP opacity testing.
However, you cannot perform any vehicle compliance testing related to the Clean Truck Check. Also, you cannot perform the OBD compliance test as part of the alternative submission option with the PSIP regulation.
Clean Truck Check credentialed testers may perform all vehicle compliance inspections, whether it is for the Clean Truck Check or PSIP. Ensure you use your tester ID received as part of the Clean Truck Check training when performing all vehicle compliance tests. To become a credentialed tester, you must take the Credentialed Tester Training and pass the exam.
