# Rochelle
Attached are two updated files for Century Aluminum sources.

Wehave included a new copy of the point location map.
The CSV file lists only the PMACT sources at Century.
The second file is the Release Point file you initially sent to Century with two added columns (yellow highlight) showing the PMACT sources at Century along with the revised Century Point Source used in the CSV submittal.
Please let us know if you need anything else.
Thank you
