The maps and data on this site are intended
to illustrate the general landscape of emissions
in and near WRAP Class I areas. For purposes
of this illustration, "near" is defined as a
50 km area surrounding the borders of the Class
I areas. Because in several cases areas are adjacent
and have similar characteristics, some areas
are analyzed and displayed together as a single
group. There are 82 groups representing 117 areas.
Start here to
review maps and tables for a particular Class
I area.
All emissions are derived from WRAP emission
databases for the year 1996. Their spatial allocation
to the analysis areas, however, are based on
several data sets (e.g., population density,
land use/cover, etc.) which span a few different
years over the 1996 period. Additional details
on the methods and data sources can be obtained
by clicking on the "About" links on other pages
within this site.
A survey of local officials in each Class I
group was conducted to ensure reasonableness
of the data and to identify activities, trends,
and proposed pojects which may affect emissions
but which may not be apparent in the emission
databases. Results of this survey are available
upon request from Lee
