Andrea,
The revised turbidity testing protocol is attached.
Thanks again for your assistance with this project!

Andrea,
We will make the requested modifications to the turbidity monitoring protocol. I will send a revised version shortly.
Regarding the tall fescue, my apologies! I had coordinated a substitution and had the plan sheet revised, but I did not
include it in the submittal. Please see the attached revised version of Sheet E000.
Hazen is under contract for the construction oversight. We have assigned a Senior Field Coordinator to the project, with
it being a 40-hour/week assignment for the duration of construction. The turbidity monitoring is one of our Senior Field
Coordinator's responsibilities. Construction oversight is not specified on the plans.
Thanks,

Thank you for addressing our comments, Keven. Things look good with a couple of exceptions:
We recommend revising the turbidity monitoring plan in the following ways:
o Since you are working during the trout moratorium and will be moving around the
impoundment, we think that keeping the minimum frequency of turbidity monitoring to 3
times a week (as opposed to Ix/week) is better.
o On days you do not measure turbidity, visual observations of turbidity upstream and
downstream of the lake should be performed.
o Please specify when during the day you will collect turbidity samples and check turbidity
visually - e.g., 2 hours after in -water work has begun.
Tall Fescue is still specified for temporary seeding on p. 3 (E000) of the 10/30/2019 plan set - this is
highly invasive and we recommend removing this from the temporary seed mix.
We are assuming that Hazen and Sawyer staff will be on -site each day, as discussed at our on -site
visit. Is this specified somewhere in the plan set? I may have missed it.
Thanks,
Andrea

Amanda and Andrea,
Attached are GGCC's responses to NCWRC's comments on the Loch Dornie dredging IP. Note that the following files are
the same files that were submitted to the USACE on October 25: Revised Sheets _20191025_reduced.pdf, Figure 5a —
Impacts Map_REV.pdf, and Pre -Construction Notification (PCN) Form_Section D revised.pdf. Please let us know if you
have any questions or remaining concerns relative to the project.
Have a wonderful weekend!

11/18/19 Version 2.1
Grandfather Golf & Country Club Loch Dornie Dredging Operations Turbidity Monitoring
Field Procedure:
1. Turbidity sampling (grab sample tested onsite via calibrated metering device) will be employed
prior to and during dredging operations —see Schedule.
2. One sample will betaken upstream of dredging operations where the Linville River crosses fairway
17 at sample station A (see map).
3. One sample will be taken downstream of Loch Dornie, downstream of the confluence of the
release pipe channel and the spillway overflow channel at station B (see map).
4. Weather description at time of sampling will be recorded (e.g., temperature). Values of turbidity
and weather conditions will be tracked and graphed.
Benchmark and Response Actions:
1. If the downstream sample site turbidity is 10 NTU or less*, dredging may continue.
2. If the downstream turbidity is the same as or lower than the upstream turbidity (e.g., 15 NTU
enters, 15 NTU leaves), dredging may continue.
3. If downstream site measurements exceed conditions under #1 or #2 above, active dredging is to
cease until condition #1 or #2 are met again; erosion control measures (e.g., turbidity curtains)
are to be examined for correct operation.
Schedule:
1. Testing at locations A and B shall be daily, on dredging operation days, defined as days when
machinery actively operates, moving soil or dredge material, below the pre-drawdown water
surface elevation. Turbidity sampling on dredging operation days will be performed
approximately two hours after in -water work commences.
2. Testing is to begin prior to dredging operations by one week, minimum, to establish a "baseline;"
see #2 under "Benchmark and Response Actions" above.

Version 2.1
3. If conditions #1 or #2 under "Benchmark and Response Actions" can be demonstrated for one
calendar week, then testing may be relaxed to three times a week (e.g., Monday, Wednesday,
Friday). If testing is relaxed to three times a week, turbidity will be visually monitored on non -
testing, dredging operation days.
4. Violations of #1 or #2, as applicable, under "Benchmark and Response Actions" during "relaxed"
timeframes will re -impose daily testing requirements.
*from 15A NCAC 02B .0211 FRESH SURFACE WATER QUALITY STANDARDS FOR CLASS C WATERS: (21)Turbidity: the
turbidity in the receiving water shall not exceed 50 Nephelometric Turbidity Units (NTU) in streams not designated as
trout waters and 10 NTU in streams, lakes, or reservoirs designated as trout waters; for lakes and reservoirs not
designated as trout waters, the turbidity shall not exceed 25 NTU; if turbidity exceeds these levels due to natural
background conditions, the existing turbidity level shall not be increased. Compliance with this turbidity standard can
be met when land management activities employ Best Management Practices (BMPs) [as defined by Rule .0202 of this
Section] recommended by the Designated Nonpoint Source Agency [as defined by Rule .0202 of this Section]. BMPs
shall be in full compliance with all specifications governing the proper design, installation, operation, and maintenance
of such BMPs
