Thanks for letting me know Heidi.  We need to get the memo into the
docket by Tuesday, as I noted yesterday.  Do we need to meet Monday to
discuss these issues?

Hi Lydia,

 

A couple of agencies did get back to me as follow up to yesterday’s
conversation on the OTAQ memo estimating Pb emissions at the airport
level.

 

There seems to be a disconnect on whether and how the airport-level
information will be used.  Some folks have noted that OTAQ represented
this analysis as *not* to be used in a regulatory process.  It sounds as
if the estimates rely heavily on a couple of key assumptions, and while
the estimates are believed to be better than estimates previously
available, they apparently remain quite course and not necessarily
sufficient to support the identification of Air Quality Monitoring
equipment.

 

Other folks would like to learn more about the methodology.

 

I will reach out to you Monday morning to identify next steps,
