CAT Chat Minutes

July 18, 2005

 

Information & Follow-up
User reminds group to slow down when driving through 436 parking lot.

User said emission from 450 cooling towers is unacceptable. Is there something that can be done to keep the matter from soiling vehicles in the lots? The problem has been ignored for years and has now become worse.

J. Quintana will follow up with J. Maclean to see what can be done, if anything.
