EPA officially announced updates to its April 2012 oil and natural gas standards for storage tanks. Updates to the regulations call for phased emission control deadlines. Storage tanks that emit 6 or more tons of VOCs per year must reduce emissions by 95%. The updated rule establishes two emissions control deadlines. The first is for tanks that come online after April 12, 2013; operators of these tanks must control VOC emissions within 60 days or by April 15, 2014, whichever is later. Operators of tanks that come online after April 12, 2014 must control VOC emissions by April 15, 2015. If storage tanks emit less than 4 tons per year of VOC emissions without controls, operators may remove existing controls from the tanks.
