Air Quality Planning
EPA establishes air quality standards, protective of public health and welfare for various pollutants. Connecticut DEEP prepares plans to attain and maintain compliance with these standards. These State Implementation Plans (SIPS) include regulations to prevent, reduce and control air pollution. These SIPs are developed through a planning process that combines technical information and air quality policy.
Large data sets defining the emissions sources (such as mobile and stationary) and meteorological data are analyzed and combined in mathematical models to inform the choice of regulatory options. These data-driven options inform decisions about air quality plan development, regulatory development and program implementation. Programs and regulations are routinely evaluated and updated with respect to changes in environmental conditions, health impact data and federal laws. In carrying out its air quality planning, DEEP takes into account a wide range of stakeholder concerns.
Air Quality Plans
State Implementation Plan (SIP) Revisions
The Connecticut State Implementation Plan (SIP) for air quality is a collective of historical plans and regulations, which were approved by EPA as meeting certain requirements of the Clean Air Act. EPA has the authority to enforce the Connecticut air quality regulations incorporated into the SIP. EPA’s record of the SIP-incorporated regulations is set out in 40 CFR Part 52 Subpart H.
Ozone Planning Efforts All of Connecticut is currently classified as nonattainment.
PM2.5 Planning Efforts All of Connecticut is currently classified as unclassifiable/attainment.
PM10 Planning Efforts All of Connecticut is currently classified as unclassifiable/attainment.
SO2 Planning Efforts All of Connecticut is currently classified as unclassifiable/attainment.
NO2 Planning Efforts All of Connecticut is currently classified as unclassifiable/attainment.
Lead Planning Efforts All of Connecticut is currently classified as unclassifiable/attainment.
EPA requires states to submit regional haze SIPs that describe the states’ measures for meeting the national goal of a return to natural visibility conditions at Class I areas (national parks and wilderness areas) by 2064.
Federal regulations are enforceable laws authorized by legislation enacted by Congress. Agencies, such as EPA are empowered to create and enforce regulations. These federal regulations are created according to the Uniform Administrative Procedures Act (APA). Connecticut comments on proposed federal regulations that would have an effect on the State's air quality.
A response-to-comments document has been posted to the eRegulations website and the proposal has been submitted to the office of the Attorney General. A copy of the response-to-comments document, the revised proposal and other related materials can be found here (05/11/2022) New!
The notice of intent has been published in eRegulations and the formal comment period was open through 5 pm on Friday, December 17, 2021. You can view the notice of intent and all related materials here (11/02/2021)
Mobile Source Planning
Mobile sources includes a variety of vehicles, engines and equipment. Sources like these account for the largest sector of man-made air pollution in Connecticut and throughout the Northeast. As such, Connecticut employs several strategies to address these emissions. Strategies include inspection and maintenance programs, diesel emissions reduction initiatives, incentive programs and more. Find the relevant information here.
