The Department of Environmental Protection amended Ch.118, Gasoline Dispensing Facilities Vapor Control. Changes repeal the January 2012 Stage II requirements for vapor controls and implement new controls to compensate for increased volatile organic compound emissions. The chapter now requires the Department to install and test pressure/vacuum vent caps on gasoline dispensing facilities by January 1, 2012, as one of the measures used to address this requirement. The measure addresses the increase in volatile organic compound emissions resulting from the removal of Stage II requirements but does not fully compensate for the removal of the original requirements. The amendment took effect April 3, 2011. http://www.maine.gov/sos/cec/rules/notices/2011/040611.html.
