The Energy Resources Conservation Board (ERCB) announces the release of the updated edition of Directive 039: Revised Program to Reduce Benzene Emissions from Glycol Dehydrators, effective immediately, which reduces benzene emissions from glycol dehydrators. This directive sets out new requirements that will ensure continued compliance with the Alberta Ambient Air Quality Objectives (AAQO). New modelling results show that to consistently meet the AAQO for the benzene one-hour average, the upstream oil and gas industry must reduce current emission targets.
The directive also sets out a revised submission date for the annual Dehydrator Benzene Inventory List (inventory). The submission deadline for the inventory has been revised to May 1 of each year (previously July 1). As some dehydrator work can be seasonal in nature, this date change supports a more appropriate timeframe for industry to respond to any issues regarding the Directive 039 requirements. The ERCB will continue to audit inventory submissions annually for compliance with Directive 039.
The 2013 inventory submission is due May 1, 2013. The new benzene emission reduction targets come into effect starting January 1, 2014, as set out in Directive 039.
