Hi,

This is the speciation language – the attachment shows where it would go in 
the RICE rule.

      “EPA assumes reduction in all species of fine particles have
      equivalent health benefits, however it is important to point out
      that there is significant uncertainty surrounding this assumption,
      and to the extent that this rule largely reflects reductions in
      only a couple of species of PM precursors, the estimates carry
      significant degree of uncertainty.”


For the Cement preamble, it would need to be added somewhere around page 272, 
with specific reference to sulfates.  In addition, similar language is needed 
for the first paragraph on page 67.


Regards,
Cortney
