RE: Response to 401 Water Quality Permit Deficiencies for the Dam Removal at Eno
River State Park [030401, 27-(10). WSIV, B, NSW]
Dear Ms. Karoly:
This letter has been written in response to your letter dated December 21, 2006 related to
deficiencies in a 401 Water Quality Permit Request submitted to the Division of Water Quality
by the Division of Parks and Recreation. Below please find the responses to your questions
related to the permit submission:
1. All intended bank stabilization work is shown on the original site plan.
2. 2. All work will be done in Riparian Buffer Zone 1, as shown on the attached map (3,700
square feet). Access to the dam will be from the adjacent parking lot. The disposal area
shown on the plan is located in the parking lot and, if used, will only be for temporary
stockpilling of excess material until its disposal in a permitted landfill. The temporary
disposal area is located outside of the 50-foot riparian buffer area. The table in Section X
of the permit has been included to show the slight modification in amount of riparian
zone impacts (50 square feet less impacts than shown in the original table).
3. The attached map shows the riparian buffer area on the original planting map.
4. All work is being done on State Park property. No easements will be required to perform
the work proposed in the original permit submittal.
5. Reference reach data was collected on the Eno River upstream of the dam site.

6. All work will be completed by mechanical means using hoe ram, jack hammers, or
similar equipment. Streamflow through the work site will continue its present course
(through the dam gates) during dam removal and the excavation of the new channel.
Dam material will be temporarily stockpilled in an existing dry area behind the dam.
Once the dam is demolished and the new channel created, the new channel will be
opened and the flow diverted through it. Once the flow is diverted through the new
channel, the dam material and river-rock material that accumulated behind the dam will
be used to rebuild and stabilize the west stream bank. Water quality problems are not
anticipated and would be temporary since most of the work is being completed in dry
areas. The material being moved is very course and not subject to suspension.
7. No mitigation credit is being sought for this project.
If you need further information concerning this matter please contact me at
[phone].

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ® No ^
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multi tiers.
Zone* Impact Multiplier Required
1 3,700 3 (2 for Catawba)
2 1.5
Total 3,700
* Zone 1 extends out 30 feet perpendicular from the top of the neaz bank of channel; Zone 2 extends an
additiona120 feet from the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. The project is currently associated with a
stream restoration project.
