Gasoline Delivery Vessel Requirements
Vapor emissions from Stage 1 gasoline deliveries to Gasoline Dispensing Facilities (GDF) in Delaware have been regulated under Delaware Code (law) since 1992.
What is regulated?
Gasoline vapor emissions are regulated because of their Volatile Organic Compound (VOC) and Hazardous Air Pollutant (HAP) content.
VOCs: Regulated reactive VOCs are defined in 7 DE Admin Code, 1101. Gasoline Delivery Vessel VOC vapor emissions are regulated under 7 DE Admin Code, 1124, 27.0 and controlled through mandatory vapor collection and return to the delivery vessel.
HAPs: The USEPA has identified many HAPs in the complex mixture called gasoline. Primary constituents of concern are: Benzene, Toluene, Ethyl benzene, and Orhtho-, Meta-, and Para-xylenes. These carcinogenic pollutants are regulated under 7 Admin Code, 1124, 27.0 and controlled through mandatory vapor collection and return to the delivery vessel.
What is required?
Permit: Those gasoline delivery vessels making a drop (delivery) to any GDF in Delaware are required to apply for and obtain a Gasoline Delivery Vessel permit prior to any delivery. Permitting may be accomplished online. For permit conditions and additional information please see the permit example.
Vapor-Tightness Test: Gasoline Delivery Vessels must verify vapor-tightness annually as demonstrated by Method 27 of 40 CFR Part 60 Appendix A (July 1, 1992).
