SUBJECT: NCIRT Review and USACE Approval of the NCDMS Pierce Terrace
Mitigation Plan Addendum / Gates County/ SAW-2020-00046

Mr. Jeremiah Dow
North Carolina Division of Mitigation Services

Dear Mr. Dow:

This letter is to inform you that the Wilmington District, Corps of Engineers (Corps)
has reviewed the proposed Mitigation Plan Addendum and Modification request for the
Pierce Terrace mitigation site (Action ID SAW-2020-00046), dated June 30, 2023. The
Pierce Terrace site is in the Chowan River Basin (Hydrologic Unit Code 03010203 &
03010204) in Gates County, NC.

In accordance with Sec. 332.8(g)(2) of the Federal Mitigation Rule, the proposed
Addendum was provided to the North Carolina Interagency Review Team (NCIRT) for
review and comment on July 31, 2023. We received no comments from the NCIRT in
response to the proposed request to modify the mitigation plan. Correspondence was
received from the State Historic Preservation Office (SHPO); however, this
correspondence indicated that the SHPO has no comment.

Based on our review, we have determined that no major concerns have been
identified with the proposed Addendum, which is considered approved with this
correspondence. This letter provides approval for the Addendum, but this does not
guarantee that the project will generate the adjusted amount of mitigation credit. As you
are aware, unforeseen issues may arise during monitoring of the project that may lead
to reduced credit. The attached credit release schedule has been updated to reflect the
change in total stream credit proposed to be generated on the site. Please ensure that
future credit release requests utilize the updated credit release schedule.

Please note that this electronic copy provided to you via email is your official copy.
Should you wish to receive a paper copy of this correspondence, please contact us.

Thank you for your time and cooperation. If you have any questions, please
contact me by email at [e-mail] or by phone at [phone].

Sincerely,

Todd Tugwell
Chief, Mitigation Branch
