Subject: Novo Nordisk - SAW 2015-02127 Permit Clarifications
Attachments: Brig ht_Sky_Project_REVISED_IP_Tables_3-5_20160303.pdf
Jennifer,
Thanks for your help processing the 401 WQC today. As a follow-up to our discussion, I have
attached the revised Tables 3, 4, and 5 from the Individual Permit Application Supporting
Documentation with the corrected/consistent impact numbers. There were no changes required for
Table 6 or the Permit Drawings. As we discussed, the minor discrepancies in impact quantities were
the result of rounding the numbers through various stages of the design process. The revised
numbers reflected in the Tables are based upon the final design as shown in the Permit Drawings.
In summary, as reflected in the tables, below are the final impact numbers for the WQC:
Novo Nordisk Preferred Site Alternative: 2.31 ac. Jurisdictional wetland
2.18 ac. Isolated wetland
Gordon Road Preferred Alternative: 3.01 ac. Jurisdictional wetland
188 If stream
Zone 1 buffer: 11,570 sq ft Zone 2 buffer: 7,756 sq ft
Total Jurisdictional Wetland Impacts for Project: 5.32 acres
It is also our understanding that the WQC was processed utilizing the DMS for mitigation
requirements for impacts associated with both the Novo Nordisk site as well as for NCDOT required
mitigation for Gordon Road Access. If Novo Nordisk wants to pursue mitigation with RES mitigation
banks, this will be processed as a permit modification at a later date along with any other
modifications that maybe required.
Thanks,
Beth

2.3 Proposed Impacts
Impacts to jurisdictional wetlands will be avoided and minimized to the extent practical.
However, permanent impacts to jurisdictional areas will be unavoidable. These
unavoidable permanent impacts within the Site and the Gordon Road Access will be
necessary for construction of the project, including total permanent impacts of 5.32 acres
to headwater forest wetlands, 2.18 acres of impact to basin wetlands, and 188 linear feet
of perennial stream. Each permanent impact area is depicted in the attached Permit
Drawings (Appendix G) and summarized in Table 3.

Table 4. On -Site Alternatives Considered
Alternative 1: This alternative layout maximizes the square footage API production
to 1,103,810 square feet and maximizes parking by allowing one contiguous parking
pad on the southern portion of the facility. The construction cost of the Gordon Road
Access is minimized by reducing the length of the road into the Site. The access road
has a "T" intersection leading into the Phase I production facilities as well as the
wastewater treatment facility. The guardhouse is located at this roadway intersection
within an adjacent wetland area. Jurisdictional impacts associated with Alternative 1
include 5.95 acres of jurisdictional wetland and 2.18 acres of isolated, non -
jurisdictional wetland. An additional 0.47 acres of wetland impact will result from the
Gordon Road Access corridor north of the railroad on this alternative. This alternative
is practical from a manufacturing logistics standpoint; however, further wetland
avoidance measures were employed for the Preferred Alternative reducing the
jurisdictional wetland impacts by 3.0 acres.

Table 5 compares the jurisdictional impacts of the Gordon Road Access alternatives considered
in the roadway design process. The functional roadway plans for each alternative, including the
Preferred Alternative, are shown in Appendix C. All Gordon Road Access alternatives utilize the
alignment shown on the Preferred Alternative Site Plan north of the railroad, which totals 0.52
acre of wetland impact. This impact is included in acreage calculations shown in Table 5.
The following alternatives were developed for the Gordon Road Access south of the railroad and
analyzed as a result of a Traffic Study prepared by Kimley-Horn and Associates to evaluate the
proposed impacts of both operational/employee traffic as well as construction traffic on
Powhatan Road. The results of the traffic study showed that Powhatan Road could accommodate
the proposed additional employee traffic with turn lane improvements at the US 70/Powhatan
intersection; however, Powhatan Road could not accommodate both operational and construction
traffic (Phase 1 and Phase 2). A summary of the traffic study is included in Appendix D.
