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,
Ms. Keven Arrance

Subject: RE: [External] RE: Loch Dornie IP - NCWRC comments
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
