In response to the modeling questions, actual 2007 TRI emissions were
used, and if “re-entrainment of dust” means vehicle traffic then no,
this was not factored into the analysis.   

 

Please let me know if you have any questions.

That’s right; 2007 TRI emissions with 1992 meteorology.

Hi Steve, 

Thanks for the response.  To be clear: this entire map, including the
maximum modeled impact and the colored contours was based on the highest
monthly average in 1992?  I remember a conversation with IDEM where you
all indicated that 2007 TRI emissions were used for air dispersion
modeling; can you clarify this for me? 

Thanks again.
