Re:	Notification of Intent to Delete Union Chemical Co., Inc. Superfund Site in Hope, Maine from the National Priorities List

 
Dear Commissioners Mercer, Whitcomb, Woodcock, Ms. Sperduto, and Dr. Finkelstein:
 
This is to notify you that EPA Region 1 is proposing to delete the Union Chemical Co., Inc. Superfund Site located in Hope, Maine from the National Priorities List (NPL).  EPA and the State of Maine, through the Department of Environmental Protection (MEDEP), have determined that all appropriate response actions under CERCLA, other than operation and maintenance, monitoring and Five-Year Reviews, have been completed.  However, this deletion does not preclude future actions under Superfund.

EPA, with the concurrence of MEDEP, will publish a Notice of Intent to Delete (NOID) the Site from the NPL in the Federal Register this month.  Assuming no substantive adverse comments are received, EPA will delete the Site from the NPL by the end of summer.  EPA will keep you apprised of the deletion process.  Whether or not the Site is deleted, the Settling Defendants under the 1992 Consent Decree will continue to perform long-term monitoring, and operation and maintenance, while EPA will continue to conduct Five-Year Reviews at the Site. 

If you have any questions or concerns, please do not hesitate to contact me. Thank you all for your time and continued support. 

Sincerely, 

Terrence Connelly 
Remedial Project Manager
