ENVIRONMENTAL MANAGEMENT COMMISSION
DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES
GROUNDWATER REMEDIATION PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Northrop Grumman Guidance and Electronics Co., Inc.
Cherokee County
FOR THE
construction and operation of a 144,000 GPD groundwater remediation facility consisting of a sediment
filtration system, air stripping system, ultraviolet reactor, hydrogen peroxide and carbon dioxide
dosing systems, and eight injection wells to remediate volatile organic compounds, primarily
consisting of chlorinated aliphatic hydrocarbons, and 1,4 -dioxane with no discharge of wastes to the
surface waters. This facility shall be constructed and operated pursuant to the application received
December 9, 2013, additional information received by the Division of Water Resources (Division) on
March 18, 2014, and in conformity with the project plans, specifications, and other supporting data filed
and approved by the Division, all of which are considered to be part of this permit.
This permit shall be effective from the date of issuance until April 11, 2019, and shall be subject to the
following conditions and limitations:
L PERFORMANCE STANDARDS
1. Upon completion of construction and prior to operation of this permitted facility, a certification
must be received from a professional engineer certifying that the permitted facility has been
installed in accordance with this permit, the approved plans and specifications, and other
supporting materials. If this project is to be completed in phases and partially certified you
shall retain.the responsibility to track further construction approved under the same permit,
and shall provide. a final certificate of cop letion once the entire project has been completed.
Mail the Certification to: WQROS-Groundwater Protection Branch,1636 Mail Service Center,
Raleigh, NC 27699-1636.
2. The Asheville Regional Office, telephone number 828-296-4500, shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities, including the initiation of
injection operations, so that an in-place inspection can be made. Such notification to the
regional supervisor shall be made during the normal office hours from 8:00 a.m. until 5.00 p.zn.
on Monday through Friday, excluding State Holidays.
WQ0036881 permit.docx Page 1 of 8

3. The treated water discharged into the injection wells must not cause a violation of Class GA
Groundwater Standards specified in 15A NCAC 02L .0202 for any constituent at the point of
injection, nor cause the migration of the contamination into unaffected areas. If the treatment
system fails to consistently achieve this standard, then additional treatment units or changes in
operational needs may be required.
4. Groundwater not treated to Class GA groundwater quality standards specified in rule 15A
NCAC 02L .0202 shall not be injected. As described in the March 18, 2014, revision of the
permit application's Attachment G - Operating and Monitoring Plans, groundwater not treated
to the standards shall be discharged to the Town of Murphy WWTP as allowed for in Moog
Components Group's Industrial User Permit #0003.
5. This permit shall become voidable if the subsurface fails to adequately assimilate the injected
fluid and may be rescinded unless the facilities are installed, maintained, and operated in a
manner that will protect the assigned water quality standards of the surface and ground waters.
6. In the event that the facility fails to perform satisfactorily, including the creation of nuisance
conditions or failure of the injection zone to adequately assimilate the injected fluid, the
Permittee shall tape immediate corrective actions including those actions that may be required
by the Division of Water Resources such as the repair, modification, or abandonment of the
injection facility. The Permittee may be required to reduce or eliminate the permitted activity to
protect the assigned water quality standards of surface and groundwaters.
7. The injection facility shall be effectively maintained and operated at all times so that there is no
contamination of groundwater outside the extent of the contaminant plume.
8. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface or ground waters resulting from the operation of this facility.
9. Any residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.
II. OPERATION AND MAINTENANCE REQUIREMENTS
1. The groundwater recovery, treatment and disposal system shall be inspected in accordance
with the March 18, 2014, revision of the permit applications Attachment G - Operation and
Monitoring Plans. If it is determined that the system is malfunctioning or leading to the release
of wastes to the environment, a threat to human health, or a nuisance, all repairs should be
made as soon as possible and reported to the Asheville Regional Office (see Section VI.
NONCOMPLIANCE NOTIFICATION). All components of the groundwater recovery,
treatment, and disposal system shall be properly weatherproofed to prevent freezing and
failure of the system.
2. Upon classification of the wastewater treatment and remediation facilities by the Water
Pollution Control System Operators Certification Commission (WPCSOCC), the Permittee shall
designate and employ a certified operator to be in responsible charge (ORC) and one or more
certified operator(s) to be back-up ORC(s) of the facilities in accordance with 15A NCAC 8G
.0201. The ORC shall visit the facilities in accordance with 15A NCAC 8G .0204 or as specified
in this permit and shall comply with all other conditions specified in these rules.
3. If requested by the owner, the Division will consider remote monitoring in lieu of physical
inspections, on a case-by-case basis, following at least two years of successful operation.

4. The Permittee shall maintain an inspection log or summary including at least the date and time
of inspection, observations made, and any maintenance, repairs, or corrective actions taken by
the Permittee. This log of inspections shall be maintained by the Permittee for a period of three
years from the date of the inspection and shall be made available to the Division or other
permitting authority, upon request.
5. Any duly authorized officer, employee, or representative of the Division may, upon
presentation of credentials, enter and inspect any property, premises or place on or related to
the disposal site or facility at any reasonable time for the purpose of determining compliance
with this permit (including inspection, observation, and sampling associated with injection and
any related facilities as provided for in N.C.G.S. 87-90), may inspect or copy any records that
must be maintained under the terms and conditions of this permit, and may obtain samples of
groundwater, surface water, injection fluids, or leachate.
