Cc: Sabrina Argentieri History: This message has been replied to and forwarded . I spoke with Theresa Rexall (sp?) at Evonik about the MM CEMS. She is happy to set up a call with the group to discuss what happened. She was not involved with MM CEMS at the time of operation but she will get the appropriate people who operated it to describe to us why they have ceased operating the CEMS. Generally, she said that there was a hard drive failure in 2009 which was repaired and then a software failure in 2011 that they were unable to repair which would have required them to replace the system. Evonik got a quote from Pall for a new unit ($250,000 for the unit and $20,000 for the tape) and did a cost benefit analysis. They decided to not replace the unit since their waste is not variable and they did not see many spikes in metals and mercury while operating it . Evonik also had some problems with the sampling train. Those could be repaired but it added to the cost to get the MM CEMS running again. As for their waste analysis , they were not doing anything different while operating the MM CEMS so there was not a cost savings associated with waste analysis while operating the MM CEMS. We can set up a call in the next few weeks. If you are interested, please let me know your availability over the next two weeks.
Thanks!

<foster_michael_l@lilly.com> Date: 10/02/2012 07:47 AM Subject: Conference call with Eli Lilly Good morning everyone. I just wanted to let you know that I have had a chat with Rick and Mike prior to our call today and I wanted to pass along some additional info . Mainly, that this conference call today is focused on technical issues. Rick and Mike can speak to their experiences with the system while they were responsible for its operation. I now know that they are no longer responsible for the incinerator and that Evonic DeGussa now owns and operates the facility (since 2010). As a result, our discussions are limited to the Eli Lilly operations.Between Pall and Eli Lilly, several excellent papers and presentations have been provided . Initially,

this is exactly what you all were looking for. I hope everyone has had a chance to go through them . In addition, I provided the links to the EPA documents that were produced specific to the alternative monitoring aspects. I hope this helps.
Jeff
