Step 2: Select the Assessment Methodology
This step helps the Handbook users to
determine the type(s) of analyses that are
appropriate for the air quality assessment.
These include emissions
inventories for:
Operational Emissions,
Construction Emissions,
HAPs and GHGs, and
Dispersion modeling for:
Airports and
Roadways.

Step 3: Conduct the Assessment
This step helps the Handbook users to set
up and conduct the air quality assessment.
This is accomplished through the
consideration of the following:
Action/Project Alternatives
Period(s) of Interest
Emission Sources and
Types of Pollutants
Necessary Input Data

This step helps Handbook users
to coordinate, document and
explain the air quality
assessment results using
methods that are both useful and
appropriate.
