AP-42 7.1 for Storage Tanks Finally Final

On November 20, 2019, the US EPA published revisions to its AP-42 emission factor guide, Chapter 7.1, for estimating air emissions from storage tanks. This webinar will review the final revisions, highlight differences from the proposed revisions, and identify the more significant potential impacts including:

-           Methodology for estimating tank cleaning emissions,

-           Revision of tank temperature equations,

-           Guidance for tanks storing hot stocks,

-           Increase of the default vapor pressure for No. 6 Oil,

-           Addition of emission factors for new deck fitting options, and

-           Statement that EPA's TANKS software “is known to have errors, and is no longer supported.”
