Under what condition can existing vapor recovery equipment be replaced by another manufacturer's equipment?

• A. If certified by CARB
• B. If allowed by the local air district
• C. If listed in the Executive Order for the vapor recovery system
• D. If the only equipment the supply house has

Answer: (C)

The correct answer relates to the regulatory framework that governs vapor recovery equipment. Specifically, when considering whether existing vapor recovery equipment can be replaced by another manufacturer's equipment, it is crucial to reference the Executive Order for the vapor recovery system. This Executive Order lays out specific criteria and standards that must be met for any equipment to be approved for use in vapor recovery applications.

When equipment is listed in the Executive Order, it means that it has undergone the necessary testing and has been validated to meet the performance and safety standards required by relevant authorities. Therefore, replacing existing equipment with another manufacturer's that is included in this order ensures compliance with regulations and maintains the integrity of the vapor recovery system.

Other options may suggest conditions for replacement, but without the explicit endorsement and listing in the Executive Order, there is no guarantee that the new equipment will be compliant with the standards necessary for efficient and safe operation.
