Standing Loss Control OverviewStanding Loss ControlControls emissions during idle periods – Heating of they the sun causes the fuel to volatize and vent intotanks bythe atmosphereStanding Loss Control is certified based on oneof the following approaches:Performance – Tests all GDF components as a system,components are certified together as a systemDesign – Tests GDF components independently.independently Once thecomponents are certified, they are added to a consolidatedEO. Mixing and matching of components is allowed.04/16/096
