This is a brief description of studies that exemplify the methods and approaches that have been developed and used by Oak Ridge National Laboratory (ORNL) researchers in conducting integrated assessments.

Integrated Assessment--Regional Scale Model

Locations of new energy facilities in western Kentucky with their associated probability of exceeding two or more 3-hour levels of 210 µg/m3 of sulfur dioxide during the growing season.

Can integrated assessment be applied at regional scales?

Air transport and ecological models were combined to evaluate the integrated impacts of eight new energy facilities in western Kentucky.

The regional approach produced quite different results from a site-by-site analysis and identified wetland ecosystems as subject to unexpectedly high risk of sulfur dioxide damage.
