Specifically, for qualifying parties under Paragraph 19, we plan to install the same GAC filtration system that is currently used in the Pilot Study locations. This GAC filtration system utilizes North American Aqua WHS-400 EPA fiberglass pressure vessels containing Calgon Filtrasorb® 600 (F600) GAC, as described in our January 11, 2018 Carbon Implementation Plan submitted to DEQ. Enclosed here, please find the piping and instrumentation plan for the proposed GAC filtration system, which shows the position of the GAC vessels and associated equipment, along with the WHS-400 and F600 data sheets. If we determine that future modifications to the GAC filtration system design may further improve performance, we will send a letter with supporting documentation to you requesting approval for the design modification. We would appreciate receiving your approval of our proposed GAC whole building filtration system as soon as possible, so that we may proceed with installation under the Consent Order. If you have any questions or need further information, please let me know. Sincerely, Brian D. Long Plant Manager Chemours – Fayetteville Works 2 Enclosure Cc: William F.
