Subject: Permit Renewal
State Stormwater Management Permit No. SW8 071203
GE- Tooling Repair Center, Castle Hayne
New Hanover County
Dear Mr. Wileman:
Effective August 1, 2013 the State Stormwater program has been transferred from the Division of Water Quality
(DWQ) to the Division of Energy, Mineral and Land Resources (DEMLR). All previous references to DWQ will
remain in older stormwater permits issued prior to August 1, 2013 until they are modified. Please note that this permit
will now reference DEMLR as the Division responsible for issuance of the permit.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacted any development approval issued
by the former Division of Water Quality under Article 21 of Chapter 143 of the General Statutes, which was current
and valid at any point between January 1, 2008, and December 31, 2010. The law extended the effective period of any
stormwater permit that was set to expire during this time flame to three (3) years from its current expiration date. On
August 2, 2010, the Governor signed Session Law 2010-177, which granted an extra year for a total of four (4) years
extension.
The Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal Application for
the subject project on June 2, 2021. The Division is hereby notifying you that permit SW8 071203 has been renewed on
June 16, 2021, and shall be effective until December 6, 2029, which includes all available extensions. For your
records, please find enclosed a renewed, updated, and re -issued permit and a copy of the renewal application. Please
keep this permit on file at all times. Please note that the renewed, updated, and re -issued permit does not impose new
or different terms; it merely restates some of the previous terms to provide you with a better understanding of your
obligations under the permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with the
terms and conditions of this state stormwater permit The plans originally approved on December 6, 2007 will remain
in full force and effect in accordance with the regulations set forth in Title 15A NCAC 2H.1000.
This permit is subject to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed
restrictions, procedures for changes of ownership, transferring the permit, and renewing the permit Failure to establish
an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions,
to transfer the permit, or to renew the permit, will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written
petition must conform to Chapter 150B of the North Carolina General Statutes, and must be filed with the OAH within
thirty (30) days of receipt of this permit. You should contact the OAH with all questions regarding the filing fee (if a
filing fee is required) and/or the details of the filing process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or
via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless such demands are made this permit
shall be final and binding.

Hi Ashley,
Per the attached permit No. SW8071203 that GE has on file, the permit is in the name "GE Hitachi Nuclear Energy"
which is why we forwarded the documentation in this name. Some of our stormwater permits are submitted in the
name Global Nuclear Fuels. However historically some of the permits were submitted under the "GE Hitachi" name as
well. I apologize for the confusion as these businesses are joint ventures. Both are here on site and all of the
stormwater water sources are from the GE site. I can try and explain the differences in the joint ventures but will need
someone from our legal team to summarize that for me.
If you wouldn't mind commenting on the document I have attached which lists the GE Hitachi name and possibly
provide me with the document you have listing GNF. Also, if you don't mind, can you forward emails with
questions/comments on the permitting directly to me and exclude Jay Wileman? While he did sign off on the
documentation, he is the CEO for the business. I am the contact for administrative tasks associated with the
permitting. I can apprise Jay of any edits. Thank you for understanding.

Karen

Good morning Mr. Wileman and Ms. Williams,
The Wilmington Regional Office has received your renewal application for permit SW8 071203. According to our records,
the current permit holder is Global Nuclear Fuel- Americas, LLC., however, GE- Hitachi Nuclear Energy Americas, LLC. is
listed on the application. State stormwater permits must be renewed by the current permittee. Please clarify how these
entities are associated or if this could be a possible error on the application. The renewal permit cannot be completed
until this information is collected. Please let me know if you have any questions, comments, or concerns.
Thank you.

Wet Detention Basin Inspection and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,

This system (check one):

incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of inspection and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
