Hi Ron,

Chapter 4:

Table 4.1:  include results for all regions.

Section 4.1.2:

Please provide discussion of why you selected a 200 km radius.  Please

discuss how the extrapolated tons would change if you assumed a smaller

radius; i.e., if the number of areas increased.  Please discuss how the

200 km radius is affected by state borders.  Please discuss how the 200

km radius is affected by natural boundaries (Great Lakes, Rocky

Mountains, Oceans, etc).  Please add note that states a sensitivity

analysis of alternative assumptions regarding the 200 km radius will be

conducted in the final RIA.

Section 4.2:

      Please provide discussion of how higher/lower impact ratios will

      affect the resulting extrapolated tons estimate.

Please provide discussion that regional specific impact ratios would

likely be more appropriate to use.

Please provide a statement that notes that regionally disaggregated

impact ratios will be conducted for the final RIA.

Cheers,

Rob
