The inspectors used a forward-looking infrared (FLIR) camera to record optical gas imaging (OGI) videos of gasoline vapors, and a toxic vapor analyzer (TVA) to measure gasoline vapor concentrations1. Any auditory, visual, and olfactory (AVO) observations were also recorded. See Appendix A for a list of photographs and videos recorded during the fuel delivery inspection. Components of the refueling Description/Observations (including any OGI or AVO activity which were observed: observations) Conditions of Equipment Equipment was observed to be capped and covered prior prior to refueling event to fueling. The vapor recovery hose was first connected to the vapor Connection of fuel and vapor recovery tank and truck header. Next, the fuel hose was lines prior to fuel transfer connected to the fuel pipe of the tank, and finally the fuel hose was connected to the truck header. Maintenance of fuel and vapor line connections during fueling event Disconnection of fuel and vapor lines after fuel Hoses were disconnected in the opposite order for which transfer they were connected. Conditions of Equipment after refueling event Caps and covers were returned after fueling.

Photographer K. Bergl K. Bergl 1 The TVA was calibrated using 500 parts per million (ppm) and 10,000 ppm methane gas standards. The methane concentrations recorded on the TVA were then converted to a ppm concentration as propane using a conversion factor of 3. This provides a conservative conversion to propane, using the guidance put forth in EPA's "Frequently Asked Questions (FAQ) for Method 25A".
