The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. This revision approves into the Connecticut SIP the provisions of Connecticut's "General Permit to Limit Potential to Emit from Major Stationary Sources of Air Pollution" (GPLPE) as they apply to the restriction of emissions of criteria pollutants for which EPA has established national ambient air quality standards. Separately, we are also approving the provisions of the GPLPE as it applies to the restriction of emissions of hazardous air pollutants (HAPs). The State issued the GPLPE on November 9, 2015. The permit imposes legally and practicably enforceable emissions limitations restricting eligible sources' potential to emit air pollutants. Such restrictions would generally allow eligible sources to avoid having to comply with reasonably available control technology (RACT) that would otherwise apply to major stationary sources, title V operating permit requirements, or other requirements that apply only to major stationary sources. This action is being taken in accordance with the Clean Air Act (CAA or the Act).
