Engineers (COE). Please note that you should get any other federal, state or local permits
before proceeding with your project, including those required by (but not limited to) Sediment
and Erosion Control, Non -Discharge, and Water Supply Watershed regulations.
The above noted Certification will expire when the associated 404 permit expires unless
otherwise specified in the General Certification. It is advised that all conditions of the
Certification are reviewed prior to initiation of the project. In addition to the requirements of the
Certification, you must also comply with the following conditions:
This approval is only valid for the purpose and design that you described in your
application. If you change your project, you must notify us in writing, and you may be
required to send us a new application for a new Certification. If total wetland fills for this

the future) exceed 150 linear feet, compensatory mitigation may be required. If the
property is sold, the new owner must be given a copy of the Certification and approval
letter; and is thereby responsible for complying with all conditions. 15A NCAC
