.18 Refinery Specifications.

A. Refinery specifications mean typical specifications and the designation of any unique additives placed into any grade of product marketed within the State.

Refinery specifications shall be filed annually in December for the succeeding calendar year and at least 10 days before any change occurs after the annual filing.

(1) Pipeline company makes direct terminal deliveries in Maryland; and

(2) Importer of the product is not a refiner.
