a Working loss control factor = 95 percent, breathing control factor =90 percent, Defect rate = 5 percent for vehicle losses.

b UG=Underground tank.  UG tank losses are based on 70 F values.  Vehicle losses are based on 80 F values.  Emissions are also shown for 60 and 100°F for comparison but not used in this study.  Vapor emissions are reduced 50 percent in Scenario 4.
