The EPA issued updates on Monday to its April 2012 oil and natural gas standards for storage tanks. The updates will phase in emission control deadlines, starting with higher-emitting tanks first. Storage tanks emitting 6 or more tons of VOCs a year must reduce emissions by 95 percent, with deadlines of April 2014 or 2015, depending on when the tank came online. The EPA also established an alternative emissions limit for some smaller tanks. The agency said it is making the changes based on recent information, showing more storage tanks will come online than it had expected.
