A MESSAGE FROM LYONDELLBASELL HOUSTON REFINERY

Dear neighbor,

I am writing you concerning the fire at our Houston Refinery on 12000 Lawndale Street earlier tonight, March 15. The fire occurred at approximately 7 p.m. in a cooling tower. The cooling tower chills down hot water to a lower temperature. Our on-site firefighting team and incident response personnel quickly contained fire and it was extinguished at 9:30 this evening.

There were no injuries and air monitoring conducted throughout the incident by LyondellBasell demonstrated no levels of concern for the community.

A thorough investigation will be conducted as to the cause of the fire. I realize this incident may have been upsetting to you or members of your family and I am sorry for any concern or inconvenience it may have caused. If you have any questions please contact Scott Buchman at Scott.Buchman@LYB.com

Sincerely,

Jerome Mauvigney

Houston Refinery Site Manager
