Subject: REQUEST FOR ADDITIONAL INFORMATION
Bynum Hydro Project (FERC # 4093)
Dear Mr. McMahan:
On March, 3, 2017, the Division of Water Resources (Division) received your application dated
February 16, 2017, requesting a 401 Water Quality Certification from the Division for the subject
project. The Division has determined that your application is incomplete and cannot be
processed. The application is on -hold until all of the following information is received:
1. A water quality monitoring plan, as outlined in our comments on the Draft License
Application on February 2, 2015, is required for processing the 401 Water Quality
Certification. [15A NCAC 02H .0506(b)(2 &3)]
a. Plan should include specific time periods for each specific monitoring frequency
proposed (e.g. weekly between June 1st and August 31st).
b. Assuming that continuous 02 monitoring in the river and tailrace will be
accomplished with deployed units, what type of units will be used to collect the data.
Low -profile units are desirable due to reduced risk of vandalism.
c. Plan should include an inspection and calibration schedule for, 02 units to prevent
membrane fouling.
d. Units in river and tailrace should be situated such that they are under water at all
flows. Plan should provide the specific depth of deployment for each unit.
e. It would be most informative to sample reservoir on river -left (powerhouse side) at
deepest point, at every foot increment in the water column to determine epi-, meta -
and hypolimnion.
