Air Quality

The documents listed below are Baseline Reports categorized topically as air quality.

This Modeling Report includes a description of the methods and datasets used in the air quality modeling analyses to estimate the Resolution Project’s air quality impacts relative to the applicable Ambient Air Quality Standards (AAQS) for criteria pollutants and to Air Quality Related Values in the near-field domain.

This modeling plan includes a description of the methods and data sets that are planned to be used in the air quality modeling analyses to estimate the Resolution Project’s air quality impacts relative to the applicable Ambient Air Quality Standards (AAQS) for criteria pollutants and to Air Quality Related Values (AQRV) in the near-field domain.
