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.
