RE: Near Roadway information for Tom Grahame





Thank you; I'll share with the broader group, as I believe this is also

of interest to Dept of Transportation.

Thanks Lydia,

Below is a note that provides a guide for Tom Grahame to information

that answers one of the questions he asked during our meeting today.

Tom Grahame asked whether we had information regarding lead

concentrations near roadways (such as gradient studies).  Deirdre

identified 2 sections of the Criteria document and 1 appendix to the

Lead Risk Assessment that deal with lead in outdoor soil and dust near

roadways.  These are:

Criteria Document

   Chapter 2, section 2.3.3 "Resuspension of Lead Containing Dust and

   Soil"

   Chapter 3, section 3.2  "Exposure:  Soil and Dust"

Risk Assessment

   Appendix F:  "Lead in Outdoor Soil and Dust near Roadways"-- this

   appendix includes a table listing key studies and summarizing their

   design/findings in terms of lead concentrations

Perhaps we could send this to Heidi to forward on to Tom, along with the

links to CD, Staff Paper, and Risk Assessment?
