An emissions inventory is a detailed list of air pollutant emissions
associated with the various sources of emissions. Emissions sources are
designated as either stationary or mobile sources. Stationary sources are
categorized as either point sources, which emit a confined air stream through a
stack or pipe, or area sources, which are numerous small activities that are not
individually tracked. Point sources include stationary sources at
manufacturing facilities and power plants. Typical area sources are
gasoline stations, dry cleaners, wood stoves, forest fires and house
paints. Mobile sources are categorized as on-road or off-road.
On-road mobile sources include passenger vehicles, motorcycles and trucks;
off-road sources include construction equipment, lawn mowers, chainsaws,
snowmobiles and motorboats.
Air emissions inventories are crucial to DEEP's efforts to improve Connecticut's air quality in furtherance of public and environmental health. Air emissions inventory information assists in planning to reduce emissions to meet federal and state mandates, tracking Connecticut's progress towards meeting our air quality goals, and mitigating significant impacts of air pollution.
Periodic Emissions Inventory (PEI)
The EPA requires a PEI every three years. The PEI quantifies actual air emissions for all categories of air pollution sources in Connecticut. Below is the Department of Energy and Environmental Protection's submittal for the 2011 PEI. (all documents are available as PDF files)
Point Source Inventory
Greenhouse Gas (GHG) Inventory
The U.S. Environmental Protection Agency (EPA) has a mandatory reporting program for GHG emissions from major point sources. More information about this program can be found here:
EPA Greenhouse Gas Reporting Program
EMIT Emissions Inventory
The EMIT application, improved for the 2010 Emissions Reporting season, is now available. Title V sources are expected to submit an electronic emissions statement. Emission statements must be submitted by March 1, 2014. Follow this link to EMIT , Connecticut's web based Emissions Reporting application.
