N.M. Admin. Code § 20.11.65.15 - GASOLINE HANDLING AND HOLDING AT RETAIL OR FLEET SERVICE STATIONS
No person shall allow loading of gasoline into an underground storage tank with greater than 3,000 gallons capacity, unless it is equipped with an approved vapor loss control system, including a submerged fill pipe, in which the displaced vapors are either continuously contained or processed such that the emission of gasoline vapors to the atmosphere do not exceed 1.15 pounds of gasoline per 1,000 gallons loaded into said tank. Liquid gasoline dispensing from the underground storage tank as well as momentary opening of the system for gasoline gauging purposes shall not be considered as vapor loss in the requirement of this Section.
