Dear Mr. Wiesner,
This letter is being provided as meeting minutes to a field meeting that occurred at the Greenbrier Full
Delivery Site (Site) on November 8, 2022. The site is currently in MY3 (2022). The meeting was conducted
to review the current Site conditions and compliance with approved performance standards with IRT
members and to receive approval for the project's MY2 (2021) DMS credit release. The Site is located off
Meadow Brook Drive and Collins Road in Yadkin County and is proposed to provide 2,413.480 stream
mitigation credits within the Yadkin River Basin 03040101.
Attendees:
Paul Wiesner —NCDMS
Kelly Phillips - NCDMS
Todd Tugwell — USACE
Erin Davis — NCDWR
Jake Byers — EPR
The meeting began at approximately 10:30 AM. There was a brief overview of the site history and the
remedial actions that have been performed to date. Supplemental site planting had been conducted in
2021. The group walked to the culvert crossing and then into the upstream conservation easement. IRT
members requested that a random vegetation monitoring plot be placed in the replanted area along the
top of left terrace on upper UT1 Reach 1 in MY5 (no vegetation monitoring in MY4). Jake stated that EPR
would put a random plot in this area as requested. No additional project issues were noted on this reach.
The IRT and DMS requested upstream and downstream photos of the project crossing and a photo of the
Collins Road culvert outlet in MY3 (2022) and future project monitoring reports.
The group then walked down to the area below the crossing. A small, vegetated overbank side channel
was noted along the left bank of UT1 Reach 1 below the culvert crossing. While stable, the IRT did request
that this area be inspected at subsequent site visits in order to make sure that it remains stable. Photos
will be taken at this location and included in future monitoring reports. The group then walked further

downstream and inspected UT1 Reach 2 and upstream Reach 3. No issues were noted here. The group
then inspected UT1A. Jake noted that channel maintenance had recently been conducted along this reach
to remove existing channel vegetation to allow the stream to flow more freely. Jake noted that in the
areas where woody vegetation was well established and was providing significant stream shading, the in -
channel vegetation was much less and channel definition was more defined. IRT members requested that
no additional channel maintenance be performed along the project reaches after MY3 (2022). Jake stated
that EPR would plant additional livestakes and/or trees along the stream banks in thinner areas to help
increase channel shading over the dormant season in 2022/2023.
The group then walked further down the valley. IRT members noted a small area of low stem density on
the top of the left terrace downstream of UT1A. Jake stated that EPR would plant some additional trees
in this area as well. The IRT recommended ring sprays around the planted stems and any supplementally
planted trees in the fescue area to help with the success of the planted and supplementally planted trees.
The group then walked down to UT1B. The group noted that significant flow was present in this reach.
One small area of overbank flow was noted with a small secondary side channel. Jake stated that some
additional livestakes and/or trees would be planted in this area to provide additional stabilization. Jake
also stated that EPR would place some straw bales in this area to prevent the stream from overflowing
into this side channel area in the near term until more vegetation was established. The IRT noted that
they had some concern along the lower extents of this reach turning into a braided wetland system and
noted that the credit along this section of stream should be considered "at risk". Paul noted that the
credits associated with this reach were well below the final 10% project credit release. The IRT requested
some additional photos and visual monitoring of this area during the winter months of MY4. Additional
live stakes will also be installed along this reach during the upcoming dormant season.
The group walked along the right bank of UT1- Reach 3 and did not have any concerns other than fescue
within the conservation easement. The IRT recommended ring sprays as necessary in the fescue areas to
help with the success of the planted and supplementally planted trees.
The group walked back to the initial meeting location. The IRT agreed that MY2 (2021) credits could be
release as proposed.
The meeting concluded at approximately 12:00 PM.
