Issued to vrilmington l:oJsing Authority
These permits for these closed loop injection well systems were issued with the condition
that they could use potable water only or a Environol-potable water mixture, but no post-
constmction documentation existed to indicate which was used. The attached letter from
the heat pump contractor indicates that only water was used, making these SQW injection
well systems. Effective Febmary 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 SQWlist database,
which keeps track of injection wells that do not require p~rmits. Likewise, the paper file
was moved to a drawer that stores SQW injection well files.

The closed loop field for the Geothermal project at Wilmington Housing Project was
designed to use water with no type of antifreeze necessary. To the best of my knowledge
there was never any antifreeze solution of any kind used.

Circulating Fluid in Geothermal Heat Pumps
Dear Mr. Cavanaugh:
The Underground Injection Control (UIC) Program of the North Carolina Division of Water Quality is
responsible for the regulation of injection well construction and operation activities within the state. In
August 2004 we spoke about the construction and operation of geothermal heat pump systems that
Carolina Temperature Control worked on for the Wilmington Housing Authority. During our
conversation you informed me that water only was used as the circulating fluid in all of these systems
and that you would submit this information in writing. To date the UIC Program has not received this
information, which is necessary to complete our files.
Your cooperation with our efforts is important to our program, and we would greatly appreciate if you or
another responsible person responded by October 22, 2004. Please submit this information by fax at

Dear Mr. Foster:
This is in response to your petition requesting variances
from the referenced Rules. Rule 2C .0213 (d)(l)(A) requires that
a well casing be installed which extends from at least 12 inches
above land surface to the to p of the in j ection zone. You
indicated in the letter dated September 27, 1995, and in the
modification to that letter dated October 19, 1995, that the
previously described injection well construction method would not
be possible due to the engineering design of the system.
Rule 2C .0213 (e)(l)(C)(i) requires that g rout be emp laced
in an in j ection well from land surface to a minimum de p th of 20
feet. You indicated in the letter dated September 2·7, 1995, and
in the modification to that letter dated October 19, 1995, that
the previously described injection well construction method would
not be possible due to the engineering design of the system.

Variance to 15A NCAC 2C .0213
Page 2
Rule 2C .0213 (c)(l)(D) requires that an in j ection well be
located 25 feet or more from a water-ti g ht sewa g e and liq uid
waste collection facility in the case of a sing le-family
dwelling . You indicated in the letter dated September 27, 1995,
and in the modification to that letter dated October 19, 1995,
that meeting the minimum separation distance requirement would
not be possible due the high density of housing (and sewage
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. Upon completion of drilling of each well, the
closed-loop piping will be installed and
grouted without delay.
2. The annular space of each well will be grouted full
length from bottom to top with a high-solids bentonite
slurry, as described and illustrated in the permit
application dated September 25, 1995. The grout will be
emplaced in a continuous operation through a pipe lowered
to the grouting point, as described in the letter dated
September 27, 1995. This construction method will
provide an adequate seal and prevent the vertical
migration of contaminants by way of the borehole.
3. The fluid to be circulated in the vertical closed-loop
heat pump system will be potable water or a propylene
glycol/ potable water mixture.
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 lSA NCAC 2C .0213 (d)(l)(A), from
lSA NCAC 2C .0213 (e)(l)(C)(i), and from 15A NCAC 2C .0213
(c)(l)(D}, as defined in lSA NCAC 2C .0118. On that basis, and
with the additional req uirement that y ou notify the Wilming ton
Re g ional Office at (910 ) 395-3900, at least 24 hours before any
well construction activities are be g un, the requested variances
from Rule 15A NCAC 2C .0213 (d)(l}(A), from !SA NCAC 2C .0213
(e)(l}(C)(i), and from Rule !SA NCAC 2C .0213 {c)(l)(d) are hereby
granted.

STANDARDS, Title 15A NCAC 2C.0200, Criteria and Standards Applicable to
Injection Wells
1914/1916 GUFFORD DRIVE, VESTA VILLAGE
WELNM-;GTON, NC
As a result of my conversations today with Ms. Karen Harmon of your office, I am submitting a
modified variance request for the subject units. This modified variance request adds a third
request for variance for emplacement of grout in bore holes. Please note that the prior variance
request submitted by letter dated September 27, 1995 incorrectly fisted the units at 1912//914
Gufford Drive, The application request and all supporting documentation correctly listed the
units as 1914/1916 Gufford Drive.
(1) We request a variance to 15A NCAC 2C.0213 (d)(1)(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)(1)(A) will not
be passible due to the engineering design of the vertical closed -loop heat pump system-
(2) We request a variance to 15A NCAC 2C. 0213 (c)(1)(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 single family dwelling due to the housing density of the site.
As the fluid is contained within a closed loop, the risk of crass -contamination is minimal.

Mr. Bob Cheek
Page2
October 19, 1995
(3) We request a variance to 15A NCAC 2C. 0213 (e)(IXC)(i) which requires emplacement of
grout from the land surface to a minimum depth of 20 feet. The injection well construction
criteria described in Rule 2C .0213 (e)(l)(C)(i) will not be possible due to the engineering
design of the vertical closed-loop heat pump system.
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

STANDARDS, Title 15A NCAC 2C.0200, Criteria and Standards Applicable to
Injection Wells
1914/1916 GUFFORD DRIVE, VESTA VILLAGE
WILMINGTON, NC
(1) We request a variance to 15A NCAC 2C.0213 (d)(1)(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)(1)(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)(1)(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 (IGSHPA) 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
seated and continued until it appears at the ground surface.

fitting shall be smooth and coated with a high quality non-stick coating.
2.3.2.1.3. Temperatures indicating crayons or a surface pyrpmeter. One temperature crayon Shall
be for the proper 'low" end temperature indication and another crayon shall be for indicating the
"high" end temperature. Use pipe manufacturer's recommended fusion temperature range.
2.3 .2.1.4. A depth gauge that is sized according to pipe diameter and corresponding fusion fitting
socket depth. The depth gauge shall be used to locate the cold ring the proper distance from the
pipe end.
2.3 .2.1.5. A metal locking cold ring clamp which supplies support for the entire circumference of
the piping material. Cold ring shall have the ability to keep the pipe end round. The cold ring
shall be used to limit the pipe depth entry into the socket face and fusion fitting socket.
2.3.2.1.6. A timing device that emits audible tone and a timing light on one second intervals.
Timer shall be used to determine proper heat cycle for the pipe and fitting. Use pipe
manufacturer's recommended heating times.
2.3.2.1.7. A number of clean, dry, 100% cotton rags used to clean the socket heater faces after
each fusion application. Rags shall be free of any cleaning solvents, grease or dirt.
PART 3 -EXECUTION
3 .1 Inspection:
General: Examine areas and conditio~ under which ground heat exchanger systems are to be
installed. Do not proceed with work until unsatisfactory conditions have been corrected in a
manner acceptable to manufacturer's recommendations. Any leaks shall be "cut-out" and repaired
in accordance to manufacturer's recommendations.
3.2 Installation of Basic Identification:
3 .2.1. General: Install mechanical identification of vertical bore holes and connecting headers.
3 .3 Boring, Trenching, and Backfilling:
General: The vertical holes of bores shall be 200 feet deep and shall be clean (no casing) and of
sufficient diameter to facilitate the installation of the U-tube assembly. The bores shall be
backfilled with appropriate material to assure pipe contact and meet local and state requirements
for sealing. The bores shall not contain large, sharp, or jagged rocks or debris. Reasonable and
prudent care shall be taken during installation and backfilling in order not to crush, cut, or kink the
pipe.
The horizontal ditches for the ground heat. exchanger header piping may be dug with a chain type
trenching machines or a backhoe. The header piping shall be buried a minimum of 36" deep. If
the soil contains sharp rocks, dig the trench 611 deeper than required and install a base of 61, of
suitable backfill (screened soil from the job site) before placing the pipe. After the piping is
installed, tested, flushed, purged, inspected, approved while still under pressure, backfill with a
suitable backfill for 6" and then finish backfilling with job Bite material. Coordinate the laying of
the header piping with existing utilities, new mechanical and electrical utilities. Prepare .
dimensioned drawing of the complete ground heat exchanger piping system before backfilling.
3.4 Installation of Piping:
3.4.1. General:
3 .4 .1.1. Install piping in accordance with manufacturer's written instructions.
3.4.1.2. The pipe and fittings must be joined using the butt or socket fusion process. No other
method is acceptable. The vertical loop takeoff tee fittings may be made using tee's or the saddle
fusion process on header piping 1-1/4" and above. Exercise extreme caution to completely remove
the cutout on saddle tees. Bell reductions shall be used at all pipe reductions to eliminate trapped
air.
3.4.1.3. Use reducing socket tees when fabricating Socket type reducing headers. Consult with
manufacturer for available fittings and fabricated headers.
3.4.1.4. Avoid sharp bends in piping. Consult pipe manufacturer for minimum bend radius.
Install elbow fittings for bends which require tighter radii than manufacturer recommends. Use
only continuous pipe in sharp bends.
3.5 Testing and Cleaning
3.5.1 Cleanliness:
During installation, trash, soil and small animals Shall be kept out of the pipe. Ends of the pipe
shall be taped or capped until the pipe is joined to the circuit.
3.5.2 Flushing the Ground Heat Exchanger:
Before connection of the plastic ground heat exchanger.loops to the header lines, each loop shall
be flushed thoroughly and left filled with clean water. If the loop is not going to be joined to the
header at this time, it should be taped or capped.
3.5.3 Pressurizing:
Each U-fitting assembly (loop) shall be water filled and pressure tested to 100 psi prior to insertion
into well bore. the complete system shall be water filled and pressure tested to I 00 Psi prior to
backfill of the trenches. Every weld shall be visually and physically examined.
3 .6 Flushing and Purging:
3.6.l General:
Before backfilling the trenches all systems shall be flushed and purged of air and flow tested to
ensure all portions of the heat exchanger are properly flowing. A portable temporary purging unit
shall be utilized and shall consist of the following (See OSU/IGSHPA CL/GS Heat Pump
Systems:
Installation Guide. Figures 7.7 & 7.8, pages 152 & 153)
I. purge pump -high volume & high head,
2. open reservoir,
3. filter assembly with by-pass,
4. flow meter,
5. pressure gage,
6. connecting piping, and
7. connecting hoses.
Using the purging unit described above, flush and purge each ground heat exchanger system until
free of air, dirt, and debris. A velocity of2 ft/sec. is required in all pipe sections to remove the air.
The flushing and purging operation should be conducted with the water source heat pump piping
isolated with shut off valves. After the ground heat exchanger is completely flushed of air and
debris open the isolation valves and permit circulation through the heat pump portion of the
system until the entire system is flushed and purged.
Utilizing the purging unit conduct a pressure and flow test on the ground heat exchanger to ensure
the system is free of blockage. If the flow test indicates blockage, locate the blockage using
manufacturers recommendation, remove the blockage, then repurge and conduct the pressure and
flow test again until all portions of the system are flowing. The flow test must be observed and
approved by the Engineer or his designate before the systems can be backfilled .

Product 50YA (60 H z)
Data Water Source Comfort System
Sizes 009 thru 060
The 50YA Heat Pump is designed
for quiet, reliable and efficient
operation. By using water as a fluid
to transport heat, the 50YA can
capture the heat from the earth to
provide space heating and water
heating for domestic use. The
process can also be reversed to take
the heat and humidity from your
house and provide hot water as well
as dispose of excess heat into the
earth. The 50YA is the heart of a
system that will provide efficient
operation, indoor and outdoor
environmental benefits all with very
low maintenance. All models are
208/230v, single phase, 60 Hertz,
and are listed with ARI, UL, and
CSA. The 0I9-060 are available
with a desuperheater to provide
domestic hot water. All sizes are
available with a cupro-nickel heat
exchanger that must be used on
open loop applications.
FEATURES/BENEFITS
Unit Refrigerant Circuit
Protection -- The High Pressure
Cut-out and Thermal Overload Cut-
out will turn the compressor off
when experiencing excessive entering
water temperature or no water flow
during the cooling cycle. The Low
Temperature Cut-out guards against
water freezing due to low entering
water temperature or no water flow
during the heating cycle. The Lock-
out Relay will protect the unit from
short -cycling if the previously
mentioned safety controls turn the
unit off. This may be reset at the
thermostat.

properties, allowing optimal pipe walls, producing
efficient heat transfer to or from the soil.
Weldable (Zero -Leak -date Closed Loop)
While most installations are constructed from
continuous lengths from one coil, larger diameter
fabricated header systems, or long lengths of four inch
and larger pipe may he joined permanently by heat
fusion, providing for a zero -leak -rate joint.
Exceptionally Smooth
With a Hazen -Williams flow fact of C=155, Driscopipe'°
5300 Climate Guard pipe offers high volume flows
with low pressure loss. The unique extrusion process
imparts a mirror smooth, glossy inside diameter

diameters: s/4, 3 , 1114, 1112, 2, 3, 4 and 6 inch, larger
sizes of 8-inch to 54-inch are available upon request.
Fittings
A wide variety of fittings are available for either the
socket and butt/saddle fusion process. Standard
molded fittings are available for the above -mentioned
pipe sizes. These fittings include 900 ells, 45° ells,
caps, line tees, reducers, branch saddles, service
saddles and flange adaptors. Molded "U" bends are
available for selected smaller -diameter pipes used as
the bore -hole pipes,
injection molded U-bend fitting with polywing anchor
Custom Fabrications

of sharp or angular objects.
• When installed down -hole, as in a vertical loop,
ample precautions should be taken to make sure
the ballast used to facilitate the insertion process
does not impinge, gouge or cut into Driscopipe®
5300 Climate Guard pipe.
• Prior to installation, Climate Guard should be filled
with water and hydrostatically tested.

This specification designates the requirements for
geothermal-system pipe and fittings, made to
controlled dimensions, specifications and
requirements as per ASTM D3035-93 for pipe,
ASTM D2683 for socket fusion fittings and ASTM
D3261 for butVsaddle fusion fittings.
Material*
The needs of demanding geothermal systems require
HOPE resins exhibiting the balance of properties
offered by pipe-grade resin possessing the ASTM
D3350 cell classification No. 345434C. The approved
pipe-grade resin is Marlex® PE TR480 which is listed
in PPI TR4 as an extrusion compound.
Pipe
The extruded pipe sizes and dimensions shall
conform to the specifications and requirements of
ASTM D3035-93. The pipe shall be virgin resin with
an allowance for on-site manufacturer re-processed
resin. No recycled resin shall be used. The approved
pipe product is Driscopipe® 5300 Climate Guard pipe.
Fittings
The geothermal system pipe fittings which are
molded shall be manufactured to the dimensional
specifications and requirements of ASTM D2683 (for
socket fusion fittings) or ASTM D3261 (for butVsaddle
fusion fittings). The material used in the manufacturing
of the fitting shall be the same approved extrusion
material as the connecting pipe. For fabricated fittings,
a minimum "quick-burst" strength of the fittings shall
not be less than that of the pipe, nor less than four
times the long-term water-rated working pressure. The
approved fittings are Driscopipe® 5300 Climate Guard
pressure-component fittings.
Joints
