API’s CELE – Committee on Evaporative Loss Estimation
GEORGE L. MOROVICH
Session Goals
CELE Structure
Standards and Process
Research and Standards development
Know where to find resources you need
Current Situation
Tank emissions receive much attention
AST Owners need to: • know where to secure information for estimating
emissions inventory • have accurate information for regulators and public • respond to ever increasing requirements to
document various technologies and operational requirements
Topics
• Committee on Evaporation Loss Estimation • Committee Structure • Committee Make Up • Environmental Drivers • Current Projects • Path Forward
CELE Benefits • Your contact source for AST Emission information • Maximum input to Standards • Coordination between industry and regulation • Response to environmental issues • Continuous improvement • Incorporation of latest technologies • Credibility and improved defensibility • Global leadership

Tank Liquid Surface Temperature Emissions are driven by
liquid surface temperature
EFRTs have higher liquid surface temperatures.
A fixed roof shades the floating
roof.
