To: From: Sent: Subject: Jackson, Ryan[jackson.ryan@epa.gov] deborah.vercek@lanxess.com Tue 5/30/2017 6:05:12 PM Information requested Dear Mr. Jackson, I am following up on my voicemail to your voicemail! I tried contacting you several time. I have the information you requested but did not want to send it via email since it contains CBI. I tried mailing it to you but the letter was returned. I cannot find you via the EPA Locator and no one at the EPA help desks seems to know your address. This is the address I used on the letter. Mr Ryan Jackson U S Environmental Protection Agency HQ William Jefferson Clinton Building 1200 Pennsylvania Avenue N W Mail Code. 1101A Washington DC 20004 I found on the EPA website but it was returned saying a Suite number was required. Please provide me with the correct mailing address so that I may send you a summary of our PMN situation and answers to the various economic questions you posed. Thank you in advance. Kind regards, Debbie Vercek Best regards, Deborah Vercek LANXESS Corporation 111 RI DC Park West Drive Pittsburgh, PA 15275-1112 412-809-3709 17cv1906 Sierra Club v. EPA ED_001523_00003424-00001
