Rule 7. (1) Dispensing facilities at a vehicle manufacturer's proving grounds or other

testing facilities, or at the facilities of a manufacturer's agent, that are used exclusively for

the testing of vehicles, components, or materials are exempt from these rules.

(2) At a vehicle manufacturer's assembly facility, the fueling of production line vehicles

(3) Gasoline that is in compliance with the federal requirements and specifications for

RFG as defined in the clean air act amendments of 1990, 42 U.S.C. §7545 et seq., is exempt

from these rules.

(4) Gasoline that exceeds the vapor pressure limits does not violate these rules if the

gasoline is separately stored, sealed, clearly labeled, and not used until it is in compliance

with this rule. The label shall state that the gasoline is prohibited by Michigan law from

being sold, dispensed, supplied, offered for sale, offered for supply, transported, or

R 285.561.8 Gasoline; compliance.

Rule 8. (1) If field analysis shows that the vapor pressure is 7.0 or less, then the gasoline

will be deemed to be in compliance with the requirements in section 3 of the act.

(2) If field analysis shows that the vapor pressure is above 7.0 psi, but is not more than

8.0 psi and the gasoline contains between 9.0 and 10.0% ethanol by volume, then the

gasoline will be deemed to be in compliance with the vapor pressure requirements in

section 3 of the act.

(3) If field analysis shows the vapor pressure is between 7.0 and 7.5 psi, then the bills of

lading and other delivery documents are subject to review by the department to determine
