Historical information is given on the Ozone Transport Assessment
Group (OTAG) which was a partnership between the EPA, the Environmental
Council of the States and various industry and environmental groups
which assessed the long-range transport of ozone and ozone precursors.
This web site also presents data
and summaries for use with the designations of 8-hour ozone
nonattainment areas. It includes data from the 1996 National Emission
Trends Inventory and Emission Tracking System/Continuous Emissions
Monitoring data, Census related data, air quality data and maps.
Related data on current designated nonattainment areas are contained
the "Green
Book" which is available here. Links
to technical resources related to the ozone program are also
available. They contain copies of various policy memoranda and reports
on VOC and NOx control.
Additionally, this site contains information related to EPA effort
to develop
an implementation rule for the 8-hour National Ambient Air Quality
Standard. Issue papers and presentations for three national public
meetings are presented. These deal with topics such as area classifications,
attainment dated, mandatory controls, progress requirements, transport
of ozone, and attainment demonstration requirements.
