Jacob,
Thank you for the additional information. Your response addresses the Division's request, with the exception of number
3. It's not clear from the response to number 3 how streamflow will be maintained below the pond during pond re -fill
following construction. This may, or may not, be a concern depending on climatic/precipitation conditions at the time of
construction. The Division must ensure there is adequate streamflow downstream of the work to maintain aquatic
habitat.
I propose including a condition in the Certification that states:
Streamflow must be maintained within the stream channel downstream of the pond at all times, including during
construction/maintenance activities and pond refilling. A minimum of 50% of stream inflow shall be maintained
in the receiving stream at the pond outlet at all times, including refill.
Please let me know if this condition is acceptable, or alternatively, propose a minimum flow number at the pond outlet
that will be maintained and that is adequate to ensure downstream habitat is maintained during construction work.
Feel free to contact me if you have any questions.

Andrew,
I have attached our response package to the additional information request for the Blair 4794 project in Jackson
County. We have included the revised impact map and a copy of the WRC comment letter for the trout
moratorium. We will be submitting the JD/Hazard Classification request to Josh Colley early next week per his
recommendation. We are coordinating with Dam Safety concurrently to requesting the 404/401 as completing the work
before the trout moratorium is critical due to the current instability of the site entrance. Thank you for your attention to
this and please let us know if you need any additional information.
Thank you,

Jennifer,
On May 16, 2023, the Division of Water Resources (Division) received your application 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. If not already done so, the Division recommends the owners contact the North Carolina Dam Safety Program to
determine any requirements from that program for the proposed work. Josh Colley ([e-mail]) is
the State Dam Safety Engineer. [15A NCAC 02H .0506(b)(3)]
2. The proposed spillway profile and cross section figures provided with the PCN do not have units depicted along
the axes or a clear scale. Please revise those figures to include the units of measure along the axes. [15A NCAC
02H .0502(a)(9)]
3. Please provide a construction sequence for the installation of the spillway and include details regarding whether
the pond will be temporarily de -watered and how the work will be conducted such that there is no flowing
water over the disturbed area. Please also include details that demonstrate adequate flow will be maintained in
the receiving stream during construction to ensure maintenance of biological integrity. [15A NCAC 02H
.0506(b)(1), (2), and (3)]
4. It appears, based on the proposed spillway profile, the intent of the project is to retain the pond full pool
elevation at, or near, its existing elevation following construction. Please confirm or describe how the full pool
elevation will change after installation of the spillway. [15A NCAC 02H .0506(b)(3)]
Pursuant to Title 15A NCAC 02H .0502(e), the applicant shall furnish all of the above requested information for the
proper consideration of the application. Please provide your response by July 6, 2023. If all of the requested information
is not received, the Division will be unable to approve the application and it will be denied as incomplete. The denial of
this project will necessitate reapplication to the Division for approval, including a complete application package and
appropriate fee.
Feel free to contact me if you have any questions.
