On September 7, 2006, Dr. John Thorne, Capitolink, a consultant for the
agriculture industry, held separate telephone conversations with Beth
Hassett-Sipple and John Bachmann, Associate Director for Science/Policy
and New Program Initiatives. Dr. Thorne asked questions regarding the
form of the particulate matter (PM) standards, with specific interest in
the PM10 standards.  The EPA staff provided general information
regarding the current forms for the PM standards and referred Dr. Thorne
to the proposed rulemaking that was published on January 17, 2006 (71 FR
2620) for more information on the current review of the PM NAAQS.
