Frequently Asked Questions
How often is testing required?
CHC opacity testing is typically required on a periodic schedule, often described as biannual. The exact frequency depends on vessel type, engine classification, and current CARB regulations. We can help confirm what applies to your vessel and operating area.
What if a vessel doesn’t pass?
If a vessel does not meet opacity requirements, you’ll receive clear documentation of the results along with guidance on next steps. After any necessary maintenance or adjustments are completed, a retest can be scheduled.
How far in advance should I schedule?
We recommend scheduling as early as possible, especially as regulatory deadlines approach. During peak compliance periods, availability can become limited. Booking ahead helps ensure you secure your preferred timeframe.
Do you test fleets?
Yes. We work with operators managing multiple vessels and can coordinate fleet testing schedules to minimize downtime and streamline compliance across your operation.
Who can test my vessels?
Certified testers must have completed a training course from the California Council on Diesel Education and Technology on the proper administration of the SAE J1667 opacity test.
What about auxiliary engines on my vessel?
Auxiliary engines must meet required opacity limits but are not required to be tested in the two-year window. However, CARB staff may perform opacity testing on auxiliary engines in the field.
Opacity Testing Requirements for Commercial Harbor Craft
The main propulsion engine must pass an opacity test once per two-year period ending on March 31 of each even-numbered calendar year. The owner must submit the results to CARB.
