A. Applications for temporary exceptions to vapor pressure and vapor liquid ratio specifications may be made to the director. The director may grant exemptions at his sole discretion, when said applications contain evidence satisfactory to the director that outlets marketing gasoline in New Mexico cannot feasibly be supplied from bulk terminals furnishing specified volatility level gasoline or that customary sources of supply have been temporarily interrupted by product shortage and alternate sources furnishing specified volatility level gasoline are not available.

B. Minimum levels of lead substitutes shall be as follows:

(1) Phosphorus - 0.005 grams per U.S. gallon.

E. A vapor pressure increase not exceeding one pound per square inch shall be allowed for gasoline-alcohol blends in excess of one (1) volume percent alcohol.
