A memo documenting the repairs (with photos) is attached for your review. At the April 2020 credit release meeting, the IRT proposed a site visit once the project repairs were completed. Project credits were withheld at the 2020 credit release meeting due to the proposed stream repairs. DMS also requests IRT input regarding additional required project monitoring on the Little Pine III site. As noted in the memo; the credit release schedule indicates a 5-year stream/7-year wetland timeline. Project monitoring started in 2016 and is currently in Monitoring Year 5 (2020). All of the wetland assets on the site are wetland enhancement or wetland preservation. Prior to the project stream repairs, DMS had anticipated requesting IRT closure of the site after MY5 (2020) due to the limited wetlands and limited wetland monitoring required on the site. Based on the IRT's memo review, a potential 2021 IRT site visit and IRT input, DMS will update the 2021 credit release/ ledger and the proposed project monitoring scope accordingly. Proiect information is as follows: Little Pine Creek III DMS Project # 94903 Institution Date: 5/30/2011 DMS Design -Bid -Build (DBB) New River Basin Cataloging Unit 05050001 Alleghany County, North Carolina USACE Action ID: SAW- 2012-01299 DWR#: 2014-0041 Proposed Mitigation Protect Credits: 6,973.4 SMUs (Cold) 1.393 WMUs (Riparian) NCDEQ- DMS Project Manager: Harry Tsomides, harry.tsomides@ncdenr.gov, (828) 545-7057 The attached memo has also been uploaded to the NCDEQ SharePoint page and can be accessed here: Little Pine 3_94903_Repair Memo_Dec. 2020.pdf https://ncconnect.sharepoi nt.com/sites/I RT- DMS/Misc%20Documents/Forms/Allitems.aspx?id=%2Fsites%2FIRT%2DDMS%2FMisc%20Documents%2FLittle%20Pine %203%5F94903%5FRepair%2OMemo%5FDec%2E%202020%2Epdf&parent=%2Fsites%2FIRT%2DDMS%2FMisc%2ODocu ments Please let me know if you have questions or call to discuss.

ROY COOPER Governor MICHAEL S. REGAN Secretary TIM BAUMGARTNER Director NORTH CAROLINA Environmental Quality MEMORANDUM TO: Todd Tugwell, USACE Kim Browning, USACE Casey Haywood, USACE Erin Davis, NCDWR FROM: Harry Tsomides, NCDEQ - DMS CC: Paul Wiesner, NCDEQ - DMS Melonie Allen, NCDEQ - DMS SUBJECT: Little Pine Creek III — Update on recent stream repairs DMS #94903 USACE Action ID: SAW-2012-01299 DWR# 14-0041 Alleghany County, North Carolina DATE: December 17, 2020 The purpose of this memo is to provide an update and summary information on recent stream repairs implemented at the Little Pine III project site, to initiate discussion on the remaining monitoring which may be required to evaluate the repair success, and to update the credit release schedule if necessary. The credit release schedule indicates a 5-year stream/7-year wetland timeline. Project monitoring started in 2016 and is currently in Monitoring Year 5 (2020). The 2020 DMS Credit Ledger is attached to this memo and summarizes project credits and the current trajectory for remaining monitoring and credit releases. The 2020 DMS Credit Ledger request has been on hold until these repairs were completed and a possible IRT field visit made. DMS is planning to hold back the 2020 proposed release, and update the 2020 and 2021 credit releases as appropriate in 2021. There have been 2 recent repair events. The attached aerial map and design plan views show the repair stations and areas for each repair event. Phase 1 repairs were conducted in Fall 2019 and addressed severe tributary erosion along portions of UT2 and UT2A. Phase II repairs were conducted in Fall 2020 and addressed areas of erosion and structural failures at 2 sections along Little Pine Creek, as well as a series of small head cuts along UT I. Both repair events were designed by Water and Land Solutions (WLS) and built by Backwater Environmental. The bulk of the repairs involved soil lifts with toe wood for bank protection, stone and log steps for grade control, and minor stream realignment. Before and after photos are shown for each phase and area. s{ NORTH CRROLWAD �1 DWaNnant al BMronnbaWl DM !� North Carolina Department of Environmental Quality I Division of Mitigation Services 217 W.
