Notice of Intent of Two Revisions to the State Implementation Plan: Periodic Emissions Inventory Year 2014 and 2017
A public hearing was not requested by January 4, 2024, therefore the public hearing originally scheduled for July 23, 2024 has been cancelled.
Notice of Intent of Two Revisions to the State Implementation Plan (SIP):
Periodic Emissions Inventory for Inventory Year 2014; and
Periodic Emissions Inventory for Inventory Year 2017
The Commissioner of the Department of Energy and Environmental Protection (DEEP) hereby gives notice of intent of two revisions to the SIP to satisfy the requirements of sections 172(c)(3) and 182(a)(3)(A) of the federal Clean Air Act (CAA). Each revision to the SIP is a Periodic Emissions Inventory (PEI), one for year 2014 and one for year 2017, to satisfy inventory requirements for the 2008 and 2015 National Ambient Air Quality Standards (NAAQS) for ozone. The State of Connecticut is classified as nonattainment for the 2008 and 2015 ozone NAAQS and must therefore submit a periodic inventory of ozone precursors every three years. These two Periodic Emissions Inventories will be submitted to the U.S. Environmental Protection Agency (EPA) for review and approval as revisions to the SIP.
EPA requires each state to inventory point, nonpoint, mobile and biogenic emissions sources and report this information to EPA for the pollutants set out in the Air Emissions Reporting Rule (40 Code of Federal Regulations (CFR) 51, Subpart A) including sulfur dioxide (SO2), volatile organic compounds (VOCs), nitrogen oxides (NOx), lead and lead compounds, primary particulate matter (PM2.5, PM10), and ammonia (NH4). Various data sources were used to develop these inventories including point source emissions data reported by the owners and operators of emitting facilities within Connecticut through their annual emissions statements, EPA inventory estimates, and modeled mobile source emissions.
The authority to adopt these SIP revisions is granted by sections 22a-6 and 22a-174 of the Connecticut General Statutes (CGS). This notice is required pursuant to CAA section 110(a)(2) and 40 CFR 51.102.
