Emissions Inventory Program
The Emissions Inventory Program is responsible for compiling data on
the release of air pollutants. The Emissions Inventory Program uses
a variety of data sources and statistical modeling to calculate emissions
from stationary sources (factories and homes), mobile
sources (cars,
trains, etc.), and biogenic sources (vegetation and
soils). The
periodic compilation of the air pollutant emissions data is called an
inventory. For data compilation purposes, air
pollutants are divided into three broad categories: criteria
pollutants, hazardous air pollutants (also
known as air
toxics), and greenhouse
gases. This section is designed both to assist facilities
in Maine with the collection and submission of air pollutant emission
data and to disseminate information to the public about what those emissions
mean for their health and the environment.
Maine DEP adopts changes to Chapter 137, "Emission Statements"
On October 16, 2008, the Board of Environmental Protection adopted changes to DEP's Chapter 137, "Emission Statements." The effective date of the rule is November 8, 2008. A copy of the rule is available from the Secretary of State's web site at http://www.maine.gov/sos/cec/rules/06/096/096c137.doc. WebEx training on the revised rule was held in early December. The presentation from that training is available on our 2008 Emissions Inventory page.
2008 Annual Air Emissions Inventory
The 2008 Annual Air Emissions Inventory is due on July 1, 2009 and includes reporting of hazardous air pollutants. Please visit our 2008 Emissions Inventory page for downloads and information specific to this inventory cycle.
Emissions Inventory Information
Criteria Pollutants provides information
about the criteria pollutants and information for businesses on reporting
criteria pollutant emissions.
Greenhouse Gases provides greenhouse gas calculation tools and other
information about calculating and reporting greenhouse gas emissions.
Hazardous Air Pollutants provides information
about reporting emissions of hazardous air pollutants.
i-STEPS is the software used by the Emissions
Inventory Program to collect data on criteria pollutant emissions. This
site contains information on obtaining and using the software.
List Servers provides information about both the Maine DEP and U.S. EPA list servers used to disseminate
emissions inventory information to businesses and improve reporting
and compliance.
MAIRIS is the new emissions inventory software program being developed by the Maine DEP to report point source emissions.
How do I find out about air emissions near my
home? is the starting
point for citizens interested in learning more about air pollution in
their state and county.
