This permit number for construction and operation of 2 Type 5QW injection wells was originally
issued in October 1995 and due to expire in October 2000. Effective February 1, 1997, this type of
injection well is deemed permitted by rule and no longer requires a permit.
On this date the record for this permit was removed from the UICfile database, which keeps track of
injection wells that need permits, and added to the 5QWlist database, which keeps track of injection
wells that do not require permits. Likewise, the paper file was moved to a drawer that stores 5QW
injection well files.

Dear Mr. Foster:
This is in response to your petition requesting variances
from the referenced Rules. Rule 2C .0213 (d) (1) (A) requires
that a well casino be installed which extends from at least 12
inches above land surface to the ton of the in j ection zone.
You indicated in the letter dated September 26, 1995, that the
previously described injection well construction method would
not be possible due to the engineering design of the system.
Rule 2C . 0213 (c) (1) (D) requires that an in j ection well
be lo c a t e d 25 feet or more from a water-ti a ht sewera a e and
li quid wa ste collection facilit y in the case of a s ing le-
famil y dwelling . You indicated in the letter dated September
26, 1995, that meeting the minimum separation distance
requirement would not be possible due the high density of
housing (and sewerage pipes) at the site.

Factors that would act to mitigate any potential problems
which could adversely affect human health and/or the effective
operation of these wells, because of not meeting the
regulatory requirements, are as follows:
1. Each well will be completely filled with high-solids
bentonite grout after installation of the closed-
loop piping in the well, as described and
illustrated in the permit application dated
September 20, 1995. This construction method will
provide an adequate seal and prevent the vertical
migration of contaminants by way of the borehole.
2. The fluid to be circulated in the vertical closed-
loop heat pump system will be potable water.
Based on my review of the available information and
recommendations by our staff, it is my finding that the
combination of factors specified above are sufficient to
satisfy the conditions for approval of variances from 15A NCAC
2C .0213 (d) (1) (A) and from 15A NCAC 2C .0213 (c) (1) (D), as
defined in 15A NCAC 2C .0118. On that basis, and with the
additional requirement that you notify the Wilmington Regional
Office at [phone], at least 24 hours before any well
construction activities are begun, the requested variances
from Rule 15A NCAC 2C .0213 (d) (1) (A) and from Rule 15A NCAC
2C .0213 (c) (1) (d) are hereby granted.
The granting of these variances does not affect any of
the other requirements of the WELL CONSTRUCTION STANDARDS or
of the requirements of any other applicable laws or rules.

SUBJECT: VARIANCE TO NORTH CAROLINA WELL CONSTRUCTION
STANDARDS, Title 15A NCAC 2C.0200, Criteria and Standards Applicable to
Injection Wells
7-C NESBITT COURTS, NCl-lR
WILMINGTON,NC
(1) We request a variance to 15A NCAC 2C.0213 (d)(l)(A) which requires that a well casing
be installed which extends from at least 12 inches above land surface to the top of the
injection zone. The injection well construction criteria described in Rule 2C.0213 (d)(l)(A)
will not be possible due to the engineering design of the vertical closed-loop heat pump
system.
(2) We also request a variance to 15A NCAC 2C. 0213 (c)(l)(D) which requires a minimum
horizonal separation of 25 feet between a well and a water-tight sewerage and liquid waste
collection facility in the case of a single family dwelling due to the housing density of the
site. As the fluid is contained within a closed loop, the risk of cross-contamination is
minimal.
Each well will be drilled 200 feet deep. The grout pipe method recommended by the
International Ground Source Heat Pump Association (IGSHP A) will be followed. The closed-
loop ground heat exchanger (GHEX) loop is immediately inserted into the bore hole. Grout is
placed in one continuous operation by pumping, beginning at the bottom of the zone being
sealed and continued until it appears at the ground surface.
Mr. Bob Cheek
Page2
September 26, 1995
Grouting is an important aspect of the installation of a GHEX when used with a ground-source
heat pump system. Not only will it provide the proper heat transfer between the GHEX and the
ground necessary for the most efficient operation of the ground-source heat pump system, but it
will also provide groundwater protection.
This method of construction will prevent any fluids from entering the injection well at the
surface because all well heads will feed into a closed loop system that is underground and out of
view from the system users.
Please contact me at [phone] if you have questions or need additional information.

Ground source heating
and cooling. Cost effective,
environmentally responsible.
Even though the temperature of the air
varies dramatically through the year, the tem-
perature underground remains relatively
constant.
The basic principle of ground source
heating and cooling allows us to tap into the
earth's abundant supply of natural energy,
without depleting any resource.
Here's how the system works.
Lengths of high -strength plastic pipe are
buried beneath the earth's surface.
Water or an antOreeze solution is circu-
lated through the pipes.
In winter, the liquid in the pipes absorbs
heat from the earth, brings it through the
system and into your home.
In summer, the ground source system
reverses itself. The unit pulls heat from your
home and places it in the ground.
Savings to you.
The Addison G-Series can save you up
to 60% on your home heating costs and up to
25% on your home cooling costs.
Even more savings.
This innovative system, through its heat
recovery process, will also heat your hot water.
Typically, the water heater is the second
highest user of electricity in your home. You
can save $30 to $40 monthly, depending on
your usage.
Longer -lasting, low -maintenance.
Because the Addison system is housed
within your home, it is protected from damaging
weather. In general, this ground source system
will outlast a conventional system by several
years.
The Addison G-Senes is designed to
function with maximum output using few
moving parts. Consequently, it is far less likely
to break down or need repair, than a conven-
tional system.
Unique automatic humidity
control cycle.
This Addison system has a dual control, Ij
one setting for temperature, one for humidity.
If, for instance, your home has been cooled to
your preset temperature, but the humidity isn't u
at your preset level, the unit keeps cooling but
continues on a low speed, wringing moisture I.
from the inside air. I
Comfortable indoor environment.
Your family will enjoy a constant, comfor-
table temperature year-round. The Addison
G-Series is extremely quiet You won`t be
aware of the unit in operation.
Clean, environmentally friendly.
The G-Serles system works toward the
preservation of the environment Renewable
heat is removed from the ground. No fossil
fuels are burned. The process does not
deplete the earth's resources.
