Purpose and Scope

This Recommended Practice (RP) is designed to provide guidance to owners and operators of gasoline dispensing facilities (GDF) to effectively operate and maintain Stage I and Stage II vapor recovery systems. This guide does not address the maintenance required by qualified service technicians to perform periodic testing and major system repairs. Federal and/or State regulatory agency certified or approved vapor recovery systems/equipment must be used to maintain the efficiency of the vapor recovery system. The appropriate state and/or locality should be contacted individually for site-specific requirements.

This RP recommends the need for periodic inspections of Stage I and Stage II equipment. The equipment and the criteria for inspection are identified in highlighted text with a corresponding letter that indicates the frequency of the inspection. That is, a (D) represents a recommendation for a daily inspection; (W) recommends a weekly inspection; (M) recommends a monthly inspection; and (A) recommends an annual inspection. Appendix A is a suggested inspection checklist for the equipment and criteria identified in the text.
