Subject: Re: Request for PM Air Quality Data Follow Up

Hi Rebecca,

I sent the results for the 2008 study in June. I've re-attached the tables, and added 'Franklin 2008 

study' to the filename. Perhaps these tables got mixed up with the 2007 paper results that I sent a 

week or two before these ones (according to my records). 

Please let me know if you are looking for something else.

Thanks,

Meredith

Dear Dr. Meredith Franklin, 

My name is Rebecca Yang and I am writing to you on behalf of Dr. Lindsay Stanek and Ms. Beth 

Hassett-Sipple of the EPA. On May 2, 2009, an email was sent or forwarded to you requesting 

descriptive statistics on the air quality distribution data for PM 2.5 and/or PM10-2.5 for your 2007 

study titled, "Association between PM2.5 and all-cause and specific-cause mortality in 27 US 

communities." Unfortunately, your 2008 study titled, "PM25 composition & daily mortality in 25 

US communities," was missing from the May 2nd email request. 

With your schedule permitting, I would like to speak with you on Friday, October 30th in order to 

obtain the descriptive statistics for your 2008 study listed below. The statistics of most interest for 

the 24-hour concentrations of PM2.5 are the following: 

- 95th percentile

- 96th percentile

- 97th percentile

- 98th percentile

- 99th percentile

- maximum concentration value 

In respect for your time, if there is another researcher/co-author who may be able to handle this 

air quality data request (i.e., has easier access to the data), I would greatly appreciate his/her 

name and contact information. Please also note that your responses, in addition to any data you 

provide, will be placed in the EPA's public docket. 

Thank you so much for your understanding and support! I apologize for the inconvenience but 

the data you provide is critical for inclusion in the EPA 's Integrated Science Assessment and 

Policy Assessment Document for Particulate Matter. Please feel free to email me the descriptive 

statistics at yang.rebecca@epa.gov. Unless I hear from you otherwise, I look forward to speaking 

with you on Friday, October 30th! Thank you for your time!
