### Discussion with Evonik DeGussa **Discussion with Evonik DeGussa -**  **MM CEMS MM CEMS**  **Sarah Marshall Sarah Marshall**  **to: Jeff Ryan, Charles Hall, Dan Bivins, David** 

**Ogulei, Kim Garnett, Shannon Downey 10/04/2012 08:58 AM**  **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!

**Ogulei/R5/USEPA/US@EPA, Kim Garnett/RTP/USEPA/US@EPA, Sarah Marshall/R5/USEPA/US@EPA,**  **Cc: Richard H Lambert <lambert_richard_h@lilly.com>, Michael L Foster <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**
