I want to thank you and the other people in your office working behind the scenes for your work over the last 7 months on this UIC permit application submittal. You have done a good job leading the pack, while balancing other balls at the same time I am sure. I am very pleased with your responsiveness to my requests, and the speed with which you made the changes I requested.
