5. Compensatory Mitigation Using the Ecosystem Enhancement Program (EEP) and Onsite Restoration
and Preservation
Mitigation must be provided for the proposed impacts as specified in the table below. We understand
that you wish to make a payment to the Wetlands Restoration Fund administered by the NC
Ecosystem Enhancement Program (EEP) to meet this mitigation requirement. This has been
determined by the DWQ to be a suitable method to meet the mitigation requirement. Until the EEP
receives and clears your check (made payable to: DENR -Ecosystem Enhancement Program Office),
no impacts specified in this Authorization Certificate shall occur. The EEP should be contacted at
(919) 733-5205 if you have any questions concerning payment into a restoration fund. You have 60
days from the date of this, approval to make this payment. Additionally, you have agreed to preserve
all remaining wetlands within the well field lots (reportedly approximately 25 acres) through
placement of a permanent easement on these remaining wetlands within the well field lots as
described in your Conservation Declaration received by the DWQ on March 19, 2007. These
aforementioned methods have been determined by the DWQ to be a suitable means to meet the
mitigation requirement. For accounting purposes, this Authorization Certificate authorizes
payment into the Wetlands Restoration Fund to meet the following compensatory mitigation
requirement:
