Modification to the 401 Water Quality Certification Pursuant to Section 401 of the Federal Clean Water Act and
Neuse Buffer Rules with ADDITIONAL CONDITIONS
HIS CERTIFICATION is issued in conformity with the requirements of Section 401 Public Laws 92-500 and 95-217
the United States and subject to the North Carolina Division of Water Quality (NCDWQ) Regulations in 15 NCAC 2H
i00 and 15A NCAC 213 .0233 . This certification authorized the NCDOT to impact an additional 0.04 acres of
rmanent impacts to jurisdictional wetlands. Due to a modification in construction techniques, a decrease of 0.1 1 acres of
nporary impacts will occur for a net decrease of 0.07 acres resulting in a project total of 6.86acres. An additional 2,904
uare feet of Neuse Riparian Buffer (2,854 square feet in Zone 1 and 50 square feet in Zone 2) and an additional 29 feet
stream impacts area also approved. The project shall be constricted pursuant to the modification dated received
ptember 27, 2010. The authorized impacts are as described below:

'Subsequent to receiving the permit application, Site 16 was re-verified by the USACE and determined not to be a wetland.
Therefore, no wetland impacts occurred and no mitigation will be required for this site.
'Although area under bridge will be hand cleared, GTP requested DWQ consider this a permanent impact per USACE (total
temporary impacts based on this are 0.13 acre).

The application provides adequate assurance that the discharge of fill material into the waters of the Neuse River Basin in
conjunction with the proposed development will not result in a violation of applicable Water Quality Standards and
discharge guidelines. Therefore, the State of North Carolina certifies that this activity will not violate the applicable
portions of Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in accordance with the application
and conditions hereinafter set forth.
This approval is only valid for the purpose and design that you submitted in your modified application dated received
September 24, 2010. All the authorized activities and conditions of certification associated with the original Water
Quality Certification dated April 7, 1998 and subsequent modifications issued November 12, 2009 and August 13, 2010
still apply except where superceded by this certification. Should your project change, you are required to notify NCDWQ
and submit a new application. If the property is sold, the new owner must be given a copy of this Certification and
approval letter, and is thereby responsible for complying with all the conditions. If any additional wetland impacts, or
stream impacts, for this project (now or in the future) exceed one acre or 150 linear feet, respectively, additional
compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h) (6) and (7). Additional buffer impacts
may require compensatory mitigation as described in 15A NCAC. For this approval to remain valid, you are required to
comply with all the conditions listed below. In addition, you should obtain all other federal, state or local permits before
proceeding with your project including (but not limited to) Sediment and Erosion control, Coastal Stormwater, Non-
discharge and Water Supply watershed regulations. This Certification shall expire on the same day as the expiration date
of the corresponding Corps of Engineers Permit.
Condition(s) of Certification:
1. All other conditions written into previous Water Quality Certifications dated April 7, 1998, November 12, 2009,
and August 13, 2010 for this project still apply.
2. This modification is applicable only to the additional proposed activities.
3. The initial 401 Water Quality Certification (WQC) application for this project is dated July 10, 1997 and was
approved April 7, 1998. During the permitting negotiations in 1998 it was decided that the GTP would offer all
mitigation for the potential loss of 871 wetland acres without a provision for functional basis as part of the
credit/debit process. The initial 401 WQC has remained active and an extension was granted on October 13,
2008. Therefore, in keeping with the April 7, 1998 and the October 13, 2008 401 WQC, no mitigation ratios are
proposed as part of this certification. Instead, credits (at a 1:1 ratio) will be deducted from the remaining credits
available to the Global TransPark in the Stonyton Creek, Dover Bay, and Frog Hollow Mitigations Sites as
outlined below:
a. Additional compensatory mitigation for impacts to 0.04 acres riverine wetlands is required for a total of
6.73 acres. We understand that you have chosen to debit credits from the Stonyton Creek Conservation
Area. According to the NCDWQ's records, this site has gone through the final NCDWQ approval
process to determine the amount of credits that will ultimately be available. Nonetheless, based in
information provided to the NCDWQ, it appears at this time that there will be sufficient credits once
final approval is given to meet the required mitigation for impacts approved with this WQC. However,
should there be insufficient credits upon final approval of the sites the GTP will be required to obtain
the necessary credits by other means.
b.. Additional compensatory mitigation for impacts to 29 linear feet of stream is required for a total of 423
linear feet. We understand that you have chosen to debit credits from the Stonyton Creek Conservation
Area. According to the NCDWQ's records, this site has gone through the final NCDWQ approval
process to determine the amount of credits that will ultimately be available. Nonetheless, based in
information provided to the NCDWQ it appears at this time that there will be sufficient credits once
final approval is given to meet the required mitigation for impacts approved with this WQC. However,
should there be insufficient credits upon final approval of the sites the GTP will be required to obtain
the necessary credits by other means.
c. Additional compensatory mitigation for impacts to 17,916 square feet of riparian buffers is required for
a total of 61,539 square feet. We understand that you have chosen to debit credits from the Stonyton
Creek Conservation Area. According to the NCDWQ's records, this site has gone through the final
NCDWQ approval process to determine the amount of credits that will ultimately be available.
Nonetheless, based in information provided to the NCDWQ it appears at this time that there will be
sufficient credits once final approval is given to meet the required mitigation for impacts approved with
this WQC. However, should there be insufficient credits upon final approval of the sites the GTP will
be required to obtain the necessary credits by other means.
Remaining anticipated wetland credits available to the Global TransPark after considering all previous requests
for impacts/mitigation, including impacts associated with this modification, is shown below:
