GENERAL SUBJECT : Channelview’s 2008 Chlorine and Flow Dat a in DMR



### TOPICS DISCUSSED AND ACTION TAKEN I called Nark Gaddy from the Channelview Complex facili ty on August 25, 2010 at 3:15 pm but the phone line was disconnected. I then called Aaron Woods, the TRIS c ontact for the Channelview Complex, and left a message at 3:15 pm explaining that I was requesting verificati on of DMR chlorine and flow data from 2008.

Don Holloway of Lyondell Bassel called me on August 27, 2010 at 9:30 am and requested that I e-mail him the DMR data and any questions I may have so he can look through them and consult anyone that may have the information available. Mr. Holloway listed his e-mail address as donald.holloway@lyondellbasell.com. I sent an e-mail to Mr. Holloway on August 27, 2010 at 3:00 pm with a li st of questions regarding how and where chlorine and flow are measured, and attached a spreadsheet o f 2008 chlorine and flow data in DMR for Mr. Holloway to verify (see Table 1).

### Tommy Miller, also of Lyondell Bassel, called me on August 30, 2010 at 10:15 am in response to the e-mail I had sent Mr. Holloway. Mr. Miller confirmed that the a vailable DMR data was correct, but that some data marked as “NR” should instead been a reported value. Mr. M iller sent a spreadsheet with the corrected data set (see Table 2). Mr. Miller explained that the high chlorine concentration measured during the March sampling episode was as a result of a septic chlorinator malfuncti on. He indicated that the value was uncharacteristic fo r chlorine concentrations at the facility but that it was the correct value. Mr. Miller explained that the septic chlorinator, where the chlorine is measured, is well upstre am of where flow is measured and that no flow is measured at the septic chlorinator.Need to return call by / at/between and .
