is in receipt of your letter dated May 24, 2011 requesting termination of the compliance monitoring program for this site with the
following exceptions:

• The beaver dam in HP-3, lower King George Branch has been removed and beaver trapped;
• Vegetation monitoring in HP-2, Wetlands 2 and 3 will be continued until all agencies feel the vegetation is stable and mature.
The long-term protection mechanisms included in the approved Mitigation Plan will remain in effect in perpetuity.
