All, The business office will be closed tomorrow for our annual College of Engineering Business Office retreat. Please ensure that all purchase orders are placed in the system prior to 4:30 today to allow us time to approve them. Otherwise, they will be approved Monday morning when we return. We will not have access to email or phone so if you have an emergency please call the main office (494-4050) and they will assist you. Thank you, MaryAnne Madrid Business Manager School of Chemical Engineering Purdue University ph: 765-494-4071 fx: 765-494-4073
