Frequent Questions

Clarify that the valid range for RVP specified in the regulations has no effect on winter calculations with the Complex Model since the RVP is fixed at 8.7 psi in the winter regardless of the actual RVP of the fuel.

That is correct. Since the winter Complex Model requires the use of an RVP of 8.7 psi for both baseline and target fuels regardless of the actual RVPs, the valid range limits for RVP do not apply to the winter Complex Model calculation.(7/1/94)
