Impact Justification and Mitigation
1.
Avoidance and Minimization
la
Specifically describe measures taken to avoid or minimize the proposed impacts in designing project
Avoidance or minimization of the stream repair and stabilization work was not possible given the vicinity of the
stream to the existing substation and railroad tracks, beyond limiting the length of the over repair /stabilization only
to the unstable sections of the stream Access to the existing power pole to the south is necessary for
maintenance The existing access and pipe have fallen into a state of disrepair and will be reestablished and the
pipe replaced The stream has eroded to a depth not passable by maintenance vehicles The proposed work will
repair and stabilize the stream and install a new pipe to allow safe access to the power poles The design of the
new pipes were synchronized with the stream repair such that the over length of stream loss was kept to a very
minimum length of only 47 feet The minor amount of wetland loss is unavoidable to provide for the necessary
natural channel design used in the stream repair and to allow for the required substation expansion The existing
substation location and alignment dictated where the expansion must occur Effort was taken in the design to limit
the size of the expansion of the substation to no more than what was necessary
Furthermore, the applicant is aware of the regional conditions associated with the Nationwide Permits 18 & 27
With respect to minor discharges (Regional Conditions section 4 0) the applicant is not proposing to utilize this
permit ►n conjunction with a NWP 14 in order to create uplands And with respect to Aquatic Habitat Restoration,
Establishment, and Enhancement Activities (Regional Conditions Section 4 0) the applicant is not requesting
mitigation credits to the NCEEP for this project
1 b
Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques
Erosion and Sediment Control measures such as check dams, silt fencing, rock dams, erosion control matting and other
typical BMP's will be utilized for the expansion of the substations and road crossings
In support of the proposed site repair & stabilization, an Erosion & Sediment Control (E &SC) Plan has been prepared in
accordance with the standards as defined in the NCDENR Erosion and Sediment Control Design Manual A series of
measures are proposed for use during construction including Temporary Silt Fence, Temporary "Pump Around"
Operations, Surface Stabilization Measures, Temporary and Permanent Seeding Measures, and Streambank and
Riparian Buffer Planting Details of the various are provided in the attached Construction Drawings

additional development, which could impact nearby downstream water quality?
3b
If you answered 'yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWQ policy If you answered "no," provide a short narrative description
We have reviewed the "Draft Internal Policy, Cumulative impacts and the 401 Water Quality Certification and Isolated
Wetlands Programs" document prepared by the NC Division of Water Quality on April 10, 2004, version 2 1 The draft
states that many private developments are unlikely to cause cumulative Impacts, including projects such as urban in -fill,
most residential subdivisions and small commercial developments as well as agricultural and silwcultural operations The
Nelson Retail Substation is an expansion of an existing substation The project Is located within the Durham ETJ,
therefore the adjacent properties that have potential for development will have the following regulations to protect
downstream waters 1) the Water Supply, Watershed Protection Program which limits development densities as
well as requires protective riparian buffers and 2) the Phase 11 NPDES Stormwater Permit Program, this program
includes permitting requirements for Municipal Separate Storm Sewer Systems (MS4s) In addition to post -
construction stormwater management requirements and 3) the Jordan Lake Watershed Buffer Protection
regulations, these regulations require limited development within the riparian buffer area in addition to "diffuse flow"
requirements at a minimum and could require Best Management Practices that control nitrogen if diffuse flow
cannot be achieved We anticipate that the DWR will advise us If any additional Information is needed
4.
Sewage Disposal (DWQ Requirement)
4a Clearly detail the ultimate treatment methods and disposition (non - discharge or discharge) of wastewater generated from
the proposed project, or available capacity of the subject facility
