Executive Summary
To inform mitigation efforts, this study investigates root-causes of fugitive (unintentional) as well as venting (intentional) emissions from fixed-roof storage tanks facilities located in Alberta and British Columbia. The work highlights the importance of fugitive emission diagnosis to enables effective repairs. Outcomes include a proposed troubleshooting decision tree for use during leak detection and repair (LDAR) surveys; a critical review of gas flashing estimation methods; and techno-economic assessments for ten storage tank emission mitigation options.
