Hello Conrad,

Our stationary air sampling data corresponding to your sampling dates are attached. Your ne arest site
was the Career Center.

Let me know if you need further clarification on the data, and I'd like to know how you interpret your PM10 data in light of our PM2.5.

Your sampling was conducted in Aug 2009

- Nov 2009. Would you like PM2.5 data during this timeframe?

Dear Erin,

In reviewing the abstract you provided previously (attached), I noticed you had the following "the PM2 .5 mass measured at the three stationary sites varied from 0.07 to 27.5 micrograms/cubic meter.....".

I am very interested in the PM2.5 measured data collected at the Marietta College site (since it has the largest sampling size, 83). I would like to com pare this PM2.5 data with one of the four School Monitoring sites (see Table 1 of the report cited), which hopefully would be closest to the Marietta College site. The purpose is, once again, develop a relationship between PM2.5 and PM10 for emissions
fro m Marietta.

Can you help?

Hello Erin,

This is an old email we traded a year and a half ago. At that time, I asked you if you have any information on the relationship between PM2.5 and TSP of the PM2.5 samples you collected, and your answer was negative. Since then, we have developed an assumption for this relationship. I thought I share this information with you, whether it is useful or important to your study. This information is actually in the ferroalloy proposed rule docket.

Conrad,

You ask a good question, but I do not think we received a TSP measure

- only PM2.5. We are searching for funding to answer this question: we would like to set up simultaneous air sampling system of PM2.5 alongside a PM10 monitor to compare the difference , and conduct size

- selective sampling. Both of these would be tremendously valuable.I'm cc'ing the study's air sampling expert, Dr. Tiina Reponen, who could provide additional information

about your question.

Thanks,

Erin

Dr. Haynes,

I apologize for not getting back to you sooner. In your abstract, you
mentioned the measur ement of PM2.5 for Mn (and other metals). I wonder if you have data speciating the percentage of PM2.5 in terms of TSP. In other words, how much of the TSP is PM2.5?

Thanks.

Hello Conrad,

CBPR is Community

- Based Participatory Research. I have a NIEHS CBPR R01 study to explore the

n eurobehavioral effects of manganese exposure on children ages 7

- 9 in Marietta, OH compared to Cambridge, OH. This study is being conducted in partnership with the community, i.e., they are involved in all aspects of the study, including identification of the primary research question, design, data collection, analysis, interpretation, and translation to the community. CBPR principles are necessary to practice, I think, when working with high

- risk, underserved populations, including AppalachianAmericans a nd EJ communities. They become key players in the research process, thereby greater buy

in and better results!

Our study's fact sheet is attached. You can also learn more about the study through our website:

w ww.eh.uc.edu/cares Essentailly, we are using exposure assessment (soil, air, water and home dust), neurobehavioral assessment (postural balance, IQ, reading, learning, behavior, etc) and biological measurements (hair, urine, blood, teeth, nails) to assess exposure and related health effects.

As air may be of most interest to you,

- Dr. Tiina Reponen is leading our air sampling portion of the study. Attached is the abstract from a student poster presented at this past AAAR meeting regarding our early stationary and personal air sampling results.

Our study is not in collaboration with Dr. Bowler's research. I had extended an invitation to them to participate before we began, but it didn't work out. Dr. Ken Hudnell was enthusiastic about our advancements with the community and our project.

I'd be glad to discuss more in detail by phone. I'm reachable at

513

- 2511 today and in the office the first week of May.

All the best,

Erin

Dear Dr . Haynes,

I would like to follow up on the CBPR study that you mentioned.... what is CBPR? What are the goals of this study, and when this study is expected to be completed? Do you have some background information (like fact sheets) you could share with me on this study?I am also interested if there is any relationship, collaboration, data sharing, etc. between your study and

the one headed by Rosemarie Bowler (RARE). My colleague at Region 5, Dr. George Bollweg, provi ded the following brief description of RARE:

Regional Applied Research Effort (RARE) Cooperative Agreement In June 2009 USEPA funded a study of potential exposure to and health effects of airborne manganese in Marietta OH, titled "Relationship of Airborne Manganese Exposure to Neurobehavioral and Health
Status". Rosemarie Bowler (San Francisco State University) is principal investigator. The study surveyed and tested 100 adult Marietta citizens in August 2009 and compared them with a corresponding group of 100 Mount Vernon OH adults, also evaluated in August 2009. Neurologic and neuropsychological tests were conducted, and questionnaires and blood samples were collected. Data analysis is currently ongoing. A release of preliminary results at a public mee ting in Marietta is planned
for June 2010. Danelle Lobdell , an ORD

- NHEERL epidemiologist at RTP, is the Project Officer of this study.

More importantly, I am interested how these health studies will help me in the upcoming RTR rulemaking. Any thoughts or suggestions would be greatly appreciated.

Hello Conrad,

Thanks for the update on other Mn refinery. Marietta has the potential to be a EJ community. I have not shared the paper directly with Eramet. My working relationship with them has been through the local Neighbors for Clean Air group that meets
with Eramet routinely. I have no objections to your sharing it with them.

I'm working now on the paper reporting the results from our community

- wide survey and developed community advisory board.

Are you familiar with our NIEHS

- funded CBPR study? We are enrolling 200 children from the Marietta area and another 200 from Cambridge, OH as the control group. We have extensive neurobehavioral measures on the kids along with home dust and soil sampling, stationary air sampling and a subset ofchildren (40 intended for personal air sampling). We hope to enroll the remaining 20 kids in the

personal air sampling this spring.

I'd be glad to discuss any of these projects with you.

Dear Erin and Melissa,

Thank you for the e

- troduction. I glimpsed through your excellent paper, and I have two quick comments, all in section 2.1 on page 2.

1) Eramet is not the only Mn refinery in North America any more. There is another ferroalloy plant, Felman Production, in New Haven, West Virginia, producing ferromanganese and silicomanganese.
Felman ha s been in production for a few years. 2) I read with interest about the demographics at Marietta, with 13.6% of families being below the poverty level, and the median family income in 1999 being $36K. Would you say that the residents near

Marietta to be below the average income at Ohio? If it is, it could be a potential EJ (environmental justice) issue.

I also wonder if you have shared this paper with Eramet. If not, would you be against it for me to share
with them?

Hi Erin,

Allow me to introduce you, via email, to Conrad Chin of USEPA. As you can see from his email below, he

is on a team which is revising the ferroalloys MACT rule and has asked for our help in providing
information about Eramet. I have directed him to the Neighbors for Clean Air, sent a link to the Eramet area on our website and plan to scan and send certain relevant docum ents to him over the next several months.

I think his team would also benefit from knowing about the CARES study and the air monitoring results and modeling at your disposal. Please get in touch with him at your convenience.Best,

Melissa

Dear Ms. English,

I talked with you a week or so ago about Eramet, and I believed you inquired about USEPA's enforcement activities on the company. Unfortunately we did not have the chance to discuss about my upcoming rulemaking activities. Ferroalloys production (which includes Eramet) is one of the source categories that USE PA is required to conduct the RTR, and then promulgated regulations that would have acceptable health risks to affected residents. In other words, this is the opportunity to correct any deficiencies in the MACT rule previously promulgated.

As part of the data gathering information process, we sent out a draft Information Collection Request (ICR) this week to all the potential major ferroalloy sources, including Eramet. We are also requiring Eramet to conduct stack sampling, including metals (manganese, a rsenic, lead, cadmium, hexavalent chromium, mercury, etc.), acid gases (HCl, HF), formaldehyde, PCBs, polycyclic aromatic hydrocarbons, and dioxin/furans. Some of these pollutants we are requiring Eramet to test are only potential pollutants, not actual confirmed pollutants, and many of these pollutants are expected to be emitted in minute quantities, if any at all. Nevertheless, we will be requiring the ferroalloy facilities conducting comprehensive samplings.

We plan to use these results as input to o ur risks modeling, and then develop regulatory options based
on the risks.

We welcome your participation in this rulemaking to the extent that you would like to be involved.
