Hello Conrad,

I'm glad to help!

I can share with you our personal air sampling results in draft manuscript

form. The paper is currently under review by Sci of Total Environ

- we have

responded to the minimal reviewer comments and are awaiting approval.

We conducted postural balance assessments on 93 children (56 from Marietta and 37

from Cambridge). We have preliminary findings that I will plan to sen d you

within 2 weeks.

There are other data in the pipeline that I will share as soon as it is ready.

Looking forward to talking with you in the near future.

Erin

Dear Erin,

I am very interested to learn more about your research data, as you expected me

to be. More importantly, some of my EPA colleagues who are involved in risk

assessments would also be interested

. Is it possible that you share your

information by email(s), and we conduct a conference call after reviewing the

information? The timing of your information is excellent. As you may know, we

proposed a rule for the two existing manganese plants in Nov ember last year, and

the comment period for the proposal is ending tomorrow. Your information would

be very useful when we review the comments to the proposal.

Thanks in advance.

Subject: Marietta study updates

Hello Conrad,

I recently learned of the EPA’s review of emission standards for Ferroalloy

production.

As you know I have a long term research stud y in Marietta, Ohio focusing on Mn

exposure from the ferromanganese refinery. We have preliminary data that I’d be

glad to share with you. What would be the best mechanism for sharing these

unpublished findings?

I’m hoping our research can be useful to you.

Erin
