Subject:
Water's Edge and Sunset Pointe (Rowan Co)...
Just a quick reminder...
We discussed last year that at permit renewal for Water's Edge and Sunset Pointe (Rowan County), we would
incorporate the components of the collection systems into the non -discharge permits and thus eliminate the collection
system permits (WQCSD0619 & 0620).
Once these ND permits are reissued, we can remove the WQCSD permit numbers.
Thanks,
CB

Staff of the Mooresville Regional Office (MRO) conducted a compliance inspection on
February 11th, 2016, which included a review of the collection and treatment and
irrigation systems. The MRO would like to thank Lynn Aldridge (ORC) for his time
during the inspection.
Please note the existing permit condition(s) for sampling and reporting requirements
were not followed. The issue was discussed with the ORC on -site and in a follow-up
email request: Mr. Aldridge confirmed by email on February 28th, 2016, that the annual
soil samples had not been collected. This NOD is being issued for the following specific
condition(s):
IV. MONITORING AND REPORTING REQUIREMENTS
12. An annual representative soils analysis... shall be conducted on each
irrigationfield...
In addition, the. lagoon's .high -'water alarm currently does not trigger any response. The
MRO. recognizes the wastewater system is currently under_utilized and lagoon.water
levels are such that they are unlikely to trip an alarm; however, it is recommended
telemetry (auto -dialer) be connected. There appears to be a phone line in place but
installation -has never been completed.

WQCSD0619 Collection System
Rowan County
A compliance evaluation inspection (CEI) of the wastewater treatment system that serves
Sunset Pointe was conducted on. September 16, 2014. Enclosed is a copy of the CEI.
Overall the facility appeared in good operational condition and well maintained.
The report should be self-explanatory. After several discussions with Michael O'Connell and the
answers to the additional information request the permit should be issued in the next month by Central
Office in Raleigh. There are several items that will change to help reduce the operating costs of the
system so please note those changes for the next permit cycle.
If you have any questions, comments, or need assistance with understanding any aspect of your permit
or this report, please do not hesitate to contact me at (704)-663-1699.

MEMORANDUM
TO: Michelle McKay
Aquifer Protection Land Application Permits & Compliance Unit
FROM: Rich Hayes
Soil Scientist
Aquifer Protection Section, Raleigh Regional Office
SUBJECT: Review Comments -Express Review Application No. WQ0029635
Sunset Pointe — High Rock Lake Development, LLC
Wastewater Treatment & Drip Irrigation
Rowan County
Included below are a few review comments and questions based upon my review of the submittal
information for the Sunset Pointe — High Rock Lake Development project and the site visit performed on
December 16, 2005.
1. An old well was discovered during the site visit. Please locate this well on the site map, provide
longitude/latitude coordinates, and confirm that this well will be properly abandoned.
2. Form: PSSA 10/99 (Page 7 of 6), seal, signatures, and dates missing.
3. An old farm gully was found in the northern end of the project that lies within the proposed drip
field area. This gully is unsuitable for use as a drip area and should be removed from the drip
area. An alternative would be to fill this area with suitable soil and properly grade the site. If the
fill/grading option is chosen, a follow-up soil scientist report will be required once construction is
complete to certify that this amended area is capable of accepting the assigned amount of
wastewater.
4. The water balance is calculated using a 37.00 acre wetted area. Form: SIA 09-02 (pl0) and the
Calculations for Sunset Pointe Subdivision Treatment System & Surface Drip Application both
show the size of the wetted area as 34.7 acres. What is the exact acreage of the wetted area?
Please recalculate the water balance if the size of the wetted area is not 37.00 acres. Please make
any necessary changes in the engineering calculations if the wetted acreage is not 34.7 acres.
5. Please describe in detail how the drip area will be managed. What type of vegetative cover will
there be in the open field (presently cropland) and in the recent clear cut? Will the pine forest area
be thinned? Are there any plans to harvest trees when the pines in the forested area mature?

6. . The application indicates there will be signs posted around the application area. Please indicate
this on the plans.
7. The application indicates zones 6 and 7 to be 2.1 acres or 91,476 ft2. Sheet U-2 of the plans
indicates zones 6 and 7 to be 2.4 acres or 104,544 ft2. Please change this to be consistent.
8. The application indicates zones 13 and 14 to be 2.7 acres and 2.1 acres while the Total Pump Run
Time sheet indicates this to be opposite. On the same sheet, zones 6 and 7 are listed to have 2.4
acres each which again is inconsistent with the application.
9. The calculations indicate valve 6 has 2.4 acres while sheet U-2 indicates it has 2.5 acres.
10. The calculations indicate valve 8 has 2.5 acres while sheet U-2 indicates it has 2.4 acres.
11. The calculations indicate valve 13 has 2.7 acres while sheet U-2 indicates it has 2.5 acres.
12. The calculations indicate valve 14 has 2.1 acres while sheet U-2 indicates it has 2.7 acres.
13. The sum of the total area of each zone in the application is 34.1 acres. Please revise numbers to
make the application package consistent.

Sunset Pointe Subdivision, Goodman Lake Road

Dear Ms. McKay:
Engineering

Planning
RECEIVED / DENR/ DWQ
AQUIFER PROTECTION SECTION
JAN 1 Y 2006
This letter is addressing all ofthe items requested for additional information in your letter dated December 29, 2005 and per the
review meeting on December 29, 2005.
1. The additional information fee in the amount of $1,409.00 made payable to NCDENR has been attached to this
submittal package (High Rock Development Company, LLC Check #136).
2. The old well located near the northeastern area of the disposal field has been shown on plan sheet U-2 (with
coordinates) and included in the revised section of Mr. Eric Lappala's report.
3. The old farm gully found in the northern end ofthe project that lies within the proposed drip field area has been and the
. general area indicated on sheet U-2. Plan notes require the contractor to have the soil scientist evaluate the soil
proposed to fill and grade the existing gully and re-evaluate after the area is filled and graded for disposal.
4. The water balance has been revised by Mr. Lappala and Mr. Willcox and both revised reports and figures have been
attached to this submittal. The changes in drip surface area from 37 acres to the correct amount (as shown on plans) of
34.7 acres required an increase in wet weather storage from 52 to 56 days. Basin has been regarded accordingly on
plan sheets U-1 and U-2. -
5. Eight foot wide access roads have been provided around the perimeter of each zone of the drip fields so that the
operator can easily check the drip fields. Since the area will be cleared of underbrush and the canopy ofthe trees will
be raised to a minimum of eight feet above the forest floor, the operator will be able to check the areas of the drain
fields by driving.along the aisles. At the pump house, the operator will be able to check flows and pump run times.
This will allow the operator to tell if a zone has a leak or broken/damaged line and the operator will have to walk the
drain field. Once per year, the operator will be required to maintain the treatment area by spraying herbicide around
the perimeter ofthe fields and other areas ofthe treatment and disposal system The contractor will be required to plant
Loblolly Pine saplings in the areas that were clear cut or currently have no tree cover. The installation contractor will
thin the underbrush (3" in diameter or less) in the areas in the existing pine forest By request ofthe permit, once the
existing trees in the forested areas mature, the Homeowner's Association will be required to have the forest evaluated
by an agronomist 5 years from date of issuance of the permit and every 5 years thereafter to determine if crop
harvesting is needed.
6. On plan sheet U-2, the plans note that signs will be required to be posted around all ofthe disposal and treatment areas.
A detail ofthe sign has been shown in the lower right hand comer of plan sheet U-4.
7. The application has been revised to be consistent with plan sheet U-2.
8. The total pump run time sheet has been revised to correspond with the application for zones 13 and 14.
9. Zone valve 6 in the application has been revised to correspond with the plan sheet U-2 and the calculations.

1. Introduction
The wastewater treatment and reclaimed water land application system for Sunset Pointe is
located south of Long Ferry Road and West of Goodman Lake Road in northwestern Rowan
County, North Carolina (Figure 1). As an integrated part of the treatment system the reclaimed
wastewater will be used to irrigate the, approximately 35 .acres of mixed pine and deciduous
forest using a drip irrigation system. The Sunset Pointe wastewater treatment and drip
irrigation system will be permitted as a non -discharge facility under 15A NCAC 2H .0200.
This work was performed by Eagle Resources, P.A. under contract to High Rock Development,
LLC.
1.1. Purpose
This hydrogeologic study has been completed in support of the non -discharge permit as required
by 15A NCAC 2H .0200, and conforms to the criteria outlined in 15A NCAC 2H .0205(d)(5)(E)
and 15A'NCAC 2H .0205(d)(5)(F). The purpose of the hydrogeologic study is to provide the
necessary information and analyses to document the occurrence and movement of groundwater
beneath and in the vicinity of the planned drip irrigation area to assess the potential for
development of shallow water table conditions.
The hydrogeologic study provided information and analyses that was used in conjunction with
the results of the Soils Report (S&ME, 2005) and site development constraints provided by
Piedmont Design Associates, P.A. to document the hydrogeologic system and to assess the likely
depth to water table beneath the drip irrigation area.
1.2. Disclaimer
Some analyses contained in this report relied upon data and information provided by others.
Eagle Resources P.A. makes no representations regarding the completeness, accuracy and
reliability of that data and information.

5.3. Water supply Wells
Analysis of aerial photos and U.S.G.S. 7.5 minute topographic. maps, and location of residences from
the Rowan County GIS website show that no evidence of water supply wells within 500 feet of the
potential drip irrigation area (Figure 1). However, field investigation on December 16, 2005
discovered an old, unused well at the location shown on Figure 3 (Rev.). The depth of this well
could not be determined at the time of the field investigation. It is recommended that this well be
properly abandoned by a North Carolina licensed water well contractor prior to commencement of
the application of water to the dripfield. The NAD83 North Carolina State Plane coordinates in feet
are: Easting 1598241, Northing: 703301 as determined by Eagle Resources using a field grade GPS
(7-10 ft accuracy) The equivalent latitude and longitude of this well in decimal degrees are:
35.674907N, 80.352805W.
5.4. Water Level Measurements
Water level measurements in the piezometers were completed immediately prior to conducting slug
tests in the piezometers in November 2005. Only three of the piezometers contained water at the
time of the measurement. The water level measurements are included in Table 3. These
measurements were used to establish the likely depth to the water table in the potential sprayfield
areas, and to constrain the numerical groundwater flow model within the property boundaries.

Attn: Michelle McKay
RE: Additional Information Request for WQ0029635
Sunset Pointe Subdivision, Goodman Lake Road
Salisbury, Rowan County, NC
Dear Ms. McKay:
Engineering
Surveying
Planning
This letter is addressing all ofthe items requested for additional information in your letter dated December 29, 2005 and per the
review meeting on December 29, 2005.
1. The additional information fee in the amount of $1,409.00 made payable to NCDENR has been attached to this
submittal package (High Rock Development Company, LLC Check # 136).
2. The old well located near the northeastern area of the disposal field has been shown on plan sheet U-2 (with
coordinates) and included in the revised section of Mr. Eric Lappala's report.
3. The old farm gully found in the northern end of the project that lies within the proposed drip field area has been and the
general area indicated on sheet U-2. Plan notes require the contractor to have the soil scientist evaluate the soil
proposed to fill and grade the existing gully and re-evaluate after the area is filled and graded for disposal.
4. The water balance has been revised by Mr. Lappala and Mr. Willcox and both revised reports and figures have been
attached to this submittal. The changes in drip surface area from 37 acres to the correct amount (as shown onplans) of
34.7 acres required an increase in wet weather storage from 52 to 56 days. Basin has been regarded accordingly on
plan sheets U-1 and U-2.
5. Eight foot wide access roads have been provided around the perimeter of each zone of the drip fields so that the
operator can easily check the drip fields. Since the area will be cleared of underbrush and the canopy of the trees will
be raised to a minimum of eight feet above the forest floor, the operator will be able to check the areas of the drain
fields by driving along the aisles. At the pump house, the operator will be able to check flows and pump run times.
This will allow the operator to tell if a zone has a leak or broken/damaged line and the operator will have to walk the
drain field. Once per year, the operator will be required to maintain the treatment area by spraying herbicide around
the perimeter of the fields and other areas of the treatment and disposal system The contractor will be required to plant
Loblolly Pine saplings in the areas that were clear cut or currently have no tree cover. The installation contractor will
thin the underbrush (Y in diameter or less) in the areas in the existing pine forest. By request of the permit, once the
existing trees in the forested areas mature, the Homeowner's Association will be required to have the forest evaluated
by an agronomist 5 years from date of issuance of the permit and every 5 years thereafter to determine if crop
harvesting is needed.
6. On plan sheet U-2, the plans note that signs will be required to be posted around all of the disposal and treatment areas.
A detail of the sign has been shown in the lower right hand corner of plan sheet U-4.
7. The application has been revised to be consistent with plan sheet U-2.
8. The total pump run time sheet has been revised to correspond with the application for zones 13 and 14.
9. Zone valve 6 in the application has been revised to correspond with the plan sheet U-2 and the calculations.

10. Zone valve 8 in the application has been revised to correspond with the plan sheet U-2 and the calculations.
11. Zone valve 13 in the calculations has been revised to correspond with the plan sheet U-2 and the application.
12. Zone valve 14 in the calculations has been revised to correspond with the plan sheet U-2 and the application.
13. The sum of the total area of each zone has been revised in the application to be 34.7 acres and is consistent with all
plans, specifications, calculations, reports, etc.
We believe this information is sufficient for approval for the aforementioned project. Please feel free to contact me if any
additional information is required or if you have any questions.
Yours truly,
PIEDMONT DESIGN ASSOCIATES, PA.

1. Introduction
The wastewater treatment and reclaimed water land application system for Sunset Pointe is
located south of Long Ferry Road and West of Goodman Lake Road in northwestern Rowan
County, North Carolina (Figure 1). As an integrated part of the treatment system the reclaimed
wastewater will be used to irrigate the approximately 35 acres of mixed pine and deciduous
forest using a drip irrigation system. The Sunset Pointe wastewater treatment and drip
irrigation system will be permitted as a non -discharge facility under 15A NCAC 2H .0200.
This work was performed by Eagle Resources, P.A. under contract to High Rock Development,
LLC.
1.1. Purpose
This hydrogeologic study has been completed in support of the non -discharge permit as required
by 15A NCAC 2H .0200, and conforms to the criteria outlined in 15A NCAC 2H .0205(d)(5)(E)
and 15A'NCAC 2H .0205(d)(5)(F). The purpose of the hydrogeologic study is to provide the
necessary information and analyses to document the occurrence and movement of groundwater
beneath and in the vicinity of the planned drip irrigation area to assess the potential for
development of shallow water table conditions.
The hydrogeologic study provided information and analyses that was used in conjunction with
the results of the Soils Report (S&ME, 2005) and site development constraints provided by
Piedmont Design Associates, P.A. to document the hydrogeologic system and to assess the likely
depth to water table beneath the drip irrigation area.
1.2. Disclaimer
Some analyses contained in this report relied upon data and information provided by others.
Eagle Resources P.A. makes no representations regarding the completeness, accuracy and
reliability of that data and information.

5.3. Water Supply Wells
Analysis of aerial photos and U.S.G.S. 7.5 minute topographic maps, and location of residences from
the Rowan County GIS website show that no evidence of water supply wells within 500 feet of the
potential drip irrigation area (Figure 1). However, field investigation on December 16, 2005
discovered an old, unused well at the location shown on Figure 3 (Rev.). The depth of this well
could not be determined at the time of the field investigation. It is recommended that this well be
properly abandoned by a North Carolina licensed water well contractor prior to commencement of
the application of water to the dripfield. The NAD83 North Carolina State Plane coordinates in feet
are: Easting 1598241, Northing: 703301 as determined by Eagle Resources using a field grade GPS
(7-10 ft accuracy) The equivalent latitude and' longitude of this well in decimal degrees are:
35.674907N, 80.352805W.
5.4. Water Level Measurements
Water level measurements in the piezometers were completed immediately prior to conducting slug
tests in the piezometers in November 2005. Only three of the piezometers contained water at the
time of the measurement. The water level measurements are included in Table 3. These
measurements were used to establish the likely depth to the water table in the potential sprayfield
areas, and to constrain the numerical groundwater flow model within the property boundaries.

7.3. Groundwater Flow Model Application
The calibrated flow model was used to assess the potential for the development of water
conditions at depths less than three feet.
7.3.1. Simulated depth to water beneath drip irrigation area
The groundwater model was used to assess the likely depth to water beneath drip
irrigation area. The requirements of 15A NCAC 2H .0200 require the water table beneath
drip irrigation area to at all times be greater than one foot, and if between one and 3 feet,
that a demonstration be made that groundwater quality is not or will not be adversely
affected.
Initial recharge under the drip irrigation area was simulated by applying the average
annual drainage rate of 5.25 inches/month in/week from the S&ME water balance model.
The average recharge rate applied outside the drip irrigation area was equal to the average
annual rate under normal climatic conditions of 8.4 inches/year (0.16 inches/week)
discussed in section 7.1.4. All groundwater model analyses were steady state (non time -
varying)..
The initial recharge rate under the drip irrigation area resulted in significant portions of
the area having a water table shallower than 3 feet. Consequently, the recharge rate was
reduced in the irrigation area until only one small area remained with a simulated depth
to the watertable between 2 and 3 feet as shown in Figure 10.
7.3.2. Revised Water Balance
As discussed in the previous section, recommended drainage rate to minimize the
likelihood of the permanent watertable rising to within three feet of the land surface is 3.0
inches/month. The initial water balance prepared by S&ME used 5.25 inches/month.
Consequently, the water balance was revised using this lower drainage value. The
revision is included as Attachment D to this report. Using assumptions and approaches in
the revised water balance that have been used as part of multiple previously approved
non -discharge permit applications, the resultant wet weather storage requirements are
essentially the same as in the S&ME water balance. The recommended average annual
hydraulic loading rate from the revised water balance is 37.33 inches/year, compared to
the 40.27 inches per year in the revised water balance of the S&ME report using a wetted
area of 34.7 acres.

8. Conclusions
A defensible conceptual hydrogeologic model of the areas including the proposed drip
irrigation area has been constructed using available information from public domain
sources, field investigations, and tests by S&ME. The conceptual model developed of
subsurface geology and hydrogeology was based upon that previously developed and
used in hydrogeologic reports in support of non -discharge permits for sites in similar
geologic and hydrologic settings. Field data collected by Eagle Resources and by S&ME
substantiate this model.
At the time of field investigations in November 2005, over 20 feet of unsaturated material
is present beneath the irrigation field above the PWR. The material above the PWR is at
least 25 and as much as 35 feet deep beneath the sprayfields based upon depths to refusal
in 8 GeoprobeTM borings.
A three-dimensional groundwater flow model has been constructed and successfully
tested against available measured groundwater level measurements. The simulated
groundwater flow patterns are consistent with the conceptual model. Consequently the
model can reliably be used to assess the likely average water table configuration and
depth to water table under conditions where irrigation is applied to the existing and
expanded drip irrigation area.
Initial hydraulic conductivity values used in the simulation model are based upon field
tests, and an acceptable model calibration was achieved by increasing the initial estimates
by a factor of 10. Model values of hydraulic conductivity are typically are 10 to 20 times
larger than values determined by slug tests in small diameter wells or piezometer because
of the effects of fractures and higher permeability weathered zones. Recharge under pre -
irrigation conditions was not adjusted during model calibration, but was set at 50% of the
normal expected values because of the documented extended drought conditions in the
region.
Based upon the results of this study, the recommended drainage rate beneath the drip
irrigation area to minimize the likelihood of the permanent watertable rising to within
three feet of the land surface is 3.0 inches/month. The S&ME water balance was revised
using this lower drainage value and is included as Attachment D to this report. The
resultant wet weather storage requirements are essentially the same as in the S&ME
water balance. The recommended average annual hydraulic loading rate,from the revised
water balance is 37.33 inches/year, compared to the 40.27 inches per year in the revised
S&ME water balance using 34.7 acres of application area.

2.1.1.4. Precipitation on and Evaporation from Storage Reservoir
Surfaces
The wet -weather storage reservoir and the required five-day upset pond will be
constructed such that no surface drainage will occur into them. However, the water
balance requires the accounting of precipitation falling on the maximum area of these
reservoirs and of evaporation from the free water surface in the reservoirs when they
contain reclaimed water. The combined surface area used for the wet weather storage
reservoirs is estimated at 1.05 acres based upon drawings provided by Piedmont Design
Associates.
2.1.2. Soils and Drainage (GWQ) for Water Balance
As discussed in the Hydrogeologic Report, the recommended drainage rate to minimize
the likelihood of the permanent watertable rising to within three feet of the land surface is
3.0 inches/month. The initial water balance prepared by S&ME used 5.25 inches/month.
2.1.3. Design Reclaimed Water Discharge
The design flow rate of 75,000 gallons per day was provided by S&ME (Appendix III).
2.2. Monthly Water Balance Analysis
The revised convergent wet weather storage requirement calculation for Sunset Pointe is
included at the end of this Attachment. The wet weather storage requirements are 4.1
million gallons (N4Gal) or 54 days for a design flow of 75,000 gpd. The revised average
annual hydraulic loading rate is 37.33 inches per year, which is slightly less than the
40.27 inches per year in the S&ME water balance.
3. Conclusions
This report presents a revised monthly water balance analysis used to design wet weather
storage for the Sunset Pointe reclaimed water and irrigation system. The storage analysis
is based upon the 80th percentile wettest condition (combination of precipitation minus
losses from evapotranspiration, runoff, and drainage to groundwater). The revised water
balance used a drainage rate of 3.0 inches per month instead of the 5.25 inches per month
used in the initial water balance by S&ME.
The wet weather storage requirements are 4.1 million gallons (Mal) or 54 days for a
design flow of 75,000 gpd. This is slightly less than the 4.2 MGal or 57 days reported in
Appendix III of the S&ME report.
The revised average annual hydraulic loading rate is 37.33 inches per year, which is
slightly less than the 40.27 inches per year in the revised S&ME water balance using a
wetted area of 34.7 acres.

1. Introduction
The wastewater treatment and reclaimed water land application system for Sunset Pointe is
located south of Long Ferry Road and West of Goodman Lake Road in northwestern Rowan
County, North Carolina (Figure 1). Wastewater from'the Sunset Pointe Waste Water Treatment
Plant will be treated to North Carolina reclaimed water reuse standards as set forth in 15A
NCAC 2H .0200. As an integrated part of the treatment system the reclaimed wastewater will be
used to irrigate the approximately 37 acres of mixed pine and deciduous forest using a drip
irrigation system. The Sunset Pointe wastewater treatment and drip irrigation system will be
permitted as a non -discharge facility under 15A NCAC 2H .0200.
This work was performed by Eagle Resources, P.A. under contract to High Rock Development,
LLC.
1.1. Purpose
This hydrogeologic study has been completed in support of the non -discharge permit as required
by 15A NCAC 2H .0200, and conforms to the criteria outlined in 15A NCAC 2H .0205(d)(5)(E) .
and 15A NCAC 2H .0205(d)(5)(F). The purpose of the hydrogeologic study is to provide the
necessary information and analyses to document the occurrence and movement of groundwater
beneath and in the vicinity of the planned drip irrigation area to assess the potential for
development of shallow water table conditions.
The hydrogeologic study provided information and analyses that was used in conjunction with
the results of the Soils Report (S&ME, 2005) and site development constraints provided by
Piedmont Design Associates, P.A. to document the hydrogeologic system and to assess the likely
depth to water table beneath the drip irrigation area.

4. Project Geographic Information System and Database
Base -map features for this study were prepared from digital maps and records acquired from the
Rowan GIS website, U.S. Geological Survey website, site plans prepared by Piedmont Design
Associates, maps prepared by S&ME, and GPS Mapping by Eagle Resources, P.A... These
digital maps and datasets were used to prepare the project Geographic Information System (GIS)
and integrated Geodatabase. The commercial GIS program ArcView® version 9.0 was used for
this purpose.
The project Geodatabase for this study included the standard environmental and water resources
database used by Eagle Resources for such studies. This database is structured to be used with
either Microsoft Access or Microsoft SQL Server. The database schema includes tables that
contain information on topography, site development, well and sampling locations, results of
chemical analyses of samples, results of hydraulic tests, boring logs of test holes, well
completion information, and logs of simulation model runs.
Figure 2 shows the sources of information used for this study and their relationship to the project
GIS and Geodatabase.

S. . Field Investigation
Field investigations were conducted for the drip irrigation area to assess hydrologic and
hydrogeologic conditions, to gather data to support the conceptual and numeric groundwater now
models, and to confirm the presence of water supply wells within 500 feet of the sprayfield
boundaries.
5. 1. Test Borings
To obtain additional subsurface information beneath the drip irrigation area ten (10) GeoprobeTM
borings were installed by Protocol Sampling Services under subcontract to Eagle Resources. All
borings were taken to refusal at depths ranging from 25 to 35 feet. Cores were continuously taken in
4-foot intervals in 1.5 inch diameter clear plastic sleeves and were logged in the field to determine
lithology; conditions of saturation, and evidence of secondary permeability features such as root
holes or fractures. Logs of the borings are included in Attachment B.
Boring locations were determined by Eagle Resources using GPS (7-10 ft accuracy).
5.2. Piezometers
To obtain information on the likely depth to the shallow water table beneath the Sunset Pointe drip
irrigation area, the ten GeoprobeTM borings were completed by Protocol Sampling Services under
subcontract to Eagle Resources as piezometers using one -inch diameter PVC plastic casing and one -
inch diameter PVC well screens. The well screen length was 10 feet for all wells except MW-3
which had a screen length of 3 feet. The locations of the piezometers and borings are shown on
Figure 3 and the construction details are summarized in Table 1.
Elevations of the ground surface at the piezometers was determined from a 10-ft x 10-ft digital
elevation model constructed using ArcGIS and the Rowan County NC Department of Transportation
2-ft topographic contour digital maps. Distance from ground surface to the measuring point for
water levels was determined with a measuring tape.

' 5.3. Logs of Water Supply Wells.
Field investigations, analysis of aerial photos and U.S.G.S. 7.5 minute topographicmaps, and
location of residences from the Rowan County GIS website show that no evidence of water supply
wells within 500 feet of the potential drip irrigation area (Figure 1).
5.4. Water Level Measurements
Water level measurements in the piezometers were completed immediately prior to conducting slug
tests in the piezometers in November 2005. Only three of the piezometers contained water at the
time of the measurement. The water level measurements are included in Table 3. These
measurements were used to establish the likely depth to the water table in the potential sprayfield
areas, and to constrain the numerical groundwater flow model within the property boundaries.

5.5. Hydraulic Conductivity Tests in Piezometers
Hydraulic conductivity tests were conducted in the three (3) piezometers that were completed below
the water table using slug tests. The slug tests were conducted by rapidly injecting a known volume
of water in the piezometer and measuring the water level response with a down -hole pressure
transducer and datalogger (Solinst"m Levelogger). The results were analyzed using the Cooper-
Bredehoeft - Papadopolus (C-B-P) Method (Reference 2.) The results are summarized in Table 4 and
the analysis plots are included in Attachment C,
As documented in the Soil Scientist Evaluation Report for Sunset Pointe, S&ME conducted four (4)
tests of the saturated hydraulic conductivity (Ksat) of the site soils to depths of 1.33 and 1.92 feet
(S&ME 2005). The results of these tests are included in Table 4.
The geometric mean value of all Ksat values from the S&ME tests is approximately 0.4 ft/.day and
the geometric mean of the slug tests in piezometers is approximately 0.2 ft/day.

6. . Inventory of Private Water Supply Wells
Regulations in 15A NCAC 2H .0200 require- an applicant to identify water wells within
500 feet of sprayfield boundaries and where possible to provide information on their
construction. Field investigations, analysis of aerial photos and U.S.G.S. 7.5 minute
topographic maps, and structures from the Rowan County GIS website show no evidence
of water supply wells within 500 feet of the potential drip irrigation area.
7. Data Analysis and Modeling
This section documents the development of the conceptual hydrogeologic model for the
areas surrounding and including drip irrigation area areas, and the construction and
application of quantitative simulation models of groundwater flow to confirm the
conceptual model. The boundaries of the conceptual model used as the framework for
the groundwater flow model were taken as topographic drainage divides from a 10-ft x
10-ft digital elevation model (DEM) grid constructed from the NC DOT Rowan County
2-ft topographic contours using ARCGIS/XTools. The modeled area covers 1.12 square
miles (720 acres) centered on the drip irrigation area as shown in Figure 1.
7. 1. Conceptual Model
The conceptual model of the physiography, geology, and hydrogeology of the area is
based upon regional studies and information, supplemented by site -specific information
from field investigations.
7.1.1. Physiography and Hydrology
The drip irrigation area and the surrounding area are located in the central portion of the
Piedmont Physiographic Province of North Carolina. Based upon topography from the
Rowan County GIS website, and on site investigations by Eagle Resources, the site
comprises rolling hills that are dissected by narrow v-shaped swales, and ephemeral and
perennial streams. All of the property within the model area drains to the Crane Creek
arm of High Rock Lake (Figure 1).
Local topography was analyzed using a 10-ft x 10-ft digital elevation model (DEM)
prepared from LIDAR data as provided, by the N.C. Department of Transportation.
shows that slopes along ridges are generally less than 10 percent and that valley slopes
above some streams is greater than 10 percent.

take &aMes
7.1.2. Geology and Solis
The area containing the drip irrigation area is situated in the eastern part of the Charlotte
litho tectonic belt. The site is underlain by metamorphic, inter -bedded felsic to mafic
tuffs and flow -rock (NC Geological Survey, 1985).
No faults mapped on the state geologic map are present within the study area. The closest
mapped fault is located approximately 3.3 miles southeast of the site and strikes North -
Northeast along the boundary between the Charlotte and Carolina Slate belts. No
intrusive dikes have been mapped in the project area, although such features are present
southeast of the site and southeast of the nearest fault mentioned above.
7.1.2.1. Stratigraphy
The conceptual model of the area including the drip irrigation area divides the subsurface
into three zones based upon regional and local published studies: Soils and Saprolite,
Partially Weathered Rock, and Fractured Bedrock. The occurrence and characteristics of
these zones were confirmed using the results of cores from geoprobe soundings and
regional geologic and hydrogeologic studies (LeGrand, 1988).
7.1.2.1.1. Soils and Saprolite
Soils in the study area have been mapped by S&ME (2005) and by the National
Resources Conservation Service (MRCS, 1977). The NRCS map units for this study
were taken from an unpublished digital map prepared as part of a NCDENR state-wide
project to estimate groundwater :recharge from precipitation, soils, and topographic
position (Walt Haven, NCDENR, personal communication, 2004).
Detailed field soil mapping in the areas proposed for drip irrigation area has been done by
S&ME under contract to High Rock Development LLC. This field mapping and testing
included 29 soil borings installed to depths ranging from 45 to 72 inches and 4 shallow
hydraulic conductivity tests (Table 4). The location of the soil borings and Ksat tests
were determined by GPS by S&EC and are shown in Figure 3. The soils characteristics
and irrigation potential are summarized in the S&ME Soils Report for Sunset Pointe
(S&ME, 2005).
The bottom of the soil and saprolite zone is taken as the depth of refusal in geoprobe
soundings which ranged from 25 to 35 feet. As shown in Table 2, the average and
median depths are both 30 feet. Based. upon this value, the average thickness of the soil
and saprolite zone . in the conceptual model is taken as 30 feet.
13

Iraye PeMM-1..5
7.1.2.1.2. Partially weathered rock (PWR)
PWR is often referred to as the transition zone between soil and the parent bedrock, and
often exhibits the same properties as saprolitic soils but with higher occurrence of rock
and rock fragments. Based upon studies in similar Piedmont sites, the thickness of the
PWR in the conceptual model was taken as 15 feet.
7.1.2.1.3. Fractured Bedrock
Bedrock in the conceptual model area typically is comprised of meta -igneous rocks with
a high degree of fractures near the interface of PWR and bedrock. Joints and fractures
are common and dissipate with depth while voids and vugs are common in shallow rock
zones when weak exfoliation soil zones are encountered near PWR. Fractures that
approximately parallel the land surface are found with depth and are the result of stress
relief as a result of the removal of several thousand feet of material that has been eroded
since the granite intrusion (LeGrand, 1988)
7.1.2.1.4. Lineament Analysis
To assess the potential for the presence of fracture zones in the bedrock, a topographic
and lineament analysis was conducted. This analysis identified linear segments of
surface drainage and topographic features such as ridges and valleys (Figure 4). The
topographic features were examined by hillshade analysis of the digital elevation model
(DEM) created from the NC DOT 2-ft topographic contours for Rowan County using
ARCGIS/Spatial AnalystTM.
Several northern trending linear features are evident on Figure 4. These features may
represent zones where the granitic bedrock is more fractured along drainages, and more
resistant to erosion along ridges. However, no zones of higher permeability in the
bedrock were included in the numerical model discussed in subsequent sections of this
report.

7.1.3. Hydrogeology
The conceptual geologic model described in the previous section was used to construct the
conceptual and numerical hydrogeologic models for this study.
7.1.3.1. Hydrostratigraphy
For purposes of developing the conceptual model of groundwater flow in the study area, the
following three hydrostratigraphic units were defined:
• Layer 1: Soil and Saprolite and Alluvium along local streams;
• Layer 2: Partially Weathered Rock; and
• Layer 3: Un-weathered Fractured Bedrock.
These units were used to construct the groundwater flow model described in the next section of
this report. These units are the same as those that have been used in similar conceptual and
numerical models of groundwater flow in areas underlain by acid crystalline rocks in the eastern
Piedmont (Eagle Resources, 2003, 2004, 2005)
7.1.I LL Layer]: Soil and Saprolite
Layer 1 comprises the material from the land surface to a depth of 30 feet. The 30-foot depth is
based upon the mean and median depth of refusal in the GeoprobeTM soundings (Table 2). The
top of Layer 1 is the land surface, and the base of Layer 1 is the surface that is everywhere 30
feet below the land surface.
The hydraulic conductivity of Layer 1 was assigned an initial isotropic value equal to 0.4 ft/day
based upon the results of slug tests in piezometers and Ksat tests (Table 4 and Attachment Q.
As described in subsequent sections, as the result of model calibration and sensitivity analysis,
this value was increased to 2.7 ft/day in both the horizontal and vertical directions. The
hydraulic conductivity of the Layer 1 was assumed to be uniform and isotropic. Sensitivity to
anisotropy was tested with sensitivity analyses as discussed in section 7.2.3.
7.L3.1.2. Layer 2. Partially Weathered Rock
Layer 2 comprises the weathered bedrock from 30 feet below the land surface to a depth of 45
feet below the land surface. This depth was based upon analysis of the depth that surface casing
is set in water supply wells within the model boundary for which information was available.
The hydraulic conductivity of Layer 2 was assigned an initial value of 0.4 ft/day, or the same
initial value assigned to Layer 1. This value was increased to 2.7 ft/day as a result of model
calibration and sensitivity analyses. The hydraulic conductivity of the PWR was assumed to be
uniform and isotropic. Sensitivity to anisotropy was tested with sensitivity analyses as discussed
in section 7.2.3.

) 4eA Ma-cee
7.L3.L3. Layer 3: Fractured Granitic Bedrock
Layer 3 comprises unweathered bedrock that'extends from a depth of 45 feet below land surface
to a depth of approximately 250 feet below land surface feet. The depth to the bottom of this
layer in the conceptual model is arbitrary, but is deep enough to include the depth to which water
wells are typically completed in the vicinity of the site.
Layer 3 is assumed'to contain fractures and joints that are ubiquitously distributed throughout its
thickness, and that these fractures and joints can be considered an `equivalent porous medium'
for purposes of groundwater modeling. No attempt was made to include zones where fractures
may be more prevalent, although these are likely to be more common in stream valleys
(LeGrand, 1988).
The hydraulic conductivity of Layer 3 was assigned an initial value of 0.001 May. This value
was increased to 0.0025 ft per day based upon model calibration. The hydraulic conductivity of
the bedrock was assumed to be uniform and isotropic. Sensitivity to anisotropy was tested with
sensitivity analyses as discussed in section 7.2.3.
7.1.4. Recharge to Groundwater
The conceptual model includes recharge everywhere to the groundwater system from infiltration
of precipitation in excess of vegetation demands during periods when the soil moisture reservoir
cannot retain water against the force of gravity. Additional localized recharge also likely occurs
by infiltration of water in the upper reaches of drainages where the bedrock hydraulic
conductivity may be greater as a result of concentrated joint sets and fractures.
Quantification of recharge to groundwater is necessary to balance groundwater flow and
discharge to streams, wetlands, springs, and water supply wells. Because it is not possible to
directly measure recharge, it must be estimated and/or determined by calibration of a
groundwater flow model. Experience in the eastern Piedmont and other areas of North Carolina
has shown that the best method to estimate recharge to groundwater under non -irrigation and
irrigation conditions is by the use of physically based climate -soil -vegetation water balance
model.
NCDENR has completed the detailed mapping of estimated groundwater recharge using such a
water balance approach that uses precipitation, soil characteristics, and landscape position for
.most of the counties in North. Carolina, including Rowan County (Walt Haven, personal
communication, 2004). Previous approaches to estimating groundwater recharge in numerical
flow models in the Piedmont of North Carolina by Eagle Resources have used simulation with
the USDA Soil and Water Assessment Tool (SWAT) applied to long-term climatic records and a
daily water balance. A comparison of recharge computed using SWAT to the NCDENR values
for several of these previous study areas in the piedmont showed that the NCDENR values were
approximately equal to the long term average values computed using SWAT for the same soils.
Consequently, the NCDENR recharge values were used for this study for recharge under non -
irrigated conditions. Figure 5 .shows the average annual recharge rates for the two categories of
landscape and soil groupings used by DENR for the modeled area. Areas of groundwater
discharge along stream valleys and areas of standing water are assigned zero recharge rates.
17

take&arw5
The recharge values shown in Figure 5 represent average climatic conditions. However the
region that includes the project area has been undergoing a prolonged drought. During November
when field investigations at the site were conducted, Rowan County was classified as being in
moderate drought condition (btlp://www.ncdrought.or ). August to October precipitation in
the study area was approximately 50% less than normal
(http://www.cpc.ncep.noaa.goy/products/analysis monitorin regional monitorin 3monthuspct
pc . i . To account for the effect of the drought conditions on water levels in the model, the
initial values of recharge used were 50% of those reported by DENR for average conditions.
The values in Figure 5 were simplified for purposes of the groundwater model by averaging the
values for the gentle and moderate slopes. For normal climatic conditions, this average is 8.4
inches per year, and for drought conditions that preceded November 2005, the average is 4.2
inches per year.
Recharge from drip irrigation in excess of plant demands for purposes of groundwater modeling
was initially set to the 5.25 inches per month used for the drainage rate in the water balance
study for the site (S&ME, 2005). Model calibration runs did not include recharge from irrigation.
As discussed subsequently, irrigation recharge was reduced to 3.0 inches per month to minimize
the potential to develop water tables that would be less than three feet from the land surface.

7.1.6. Discharge from Groundwater
Groundwater discharges to the lower reaches of drainages during times of high water
levels following extended periods of precipitation. Groundwater also may discharge in
these areas after following fracture zones that are coincident with linear portions of
drainage features.
Groundwater discharge by evapotranspiration where the water table is shallow was not
included in the model because field observations and analysis of reported static water
levels showed that in general, the water table is always deeper than 5 to 10 feet. This is
deeper than vegetation in the area can extract significant quantities of groundwater.
Discharge by evapotranspiration in wetland and stream bottom areas is included in the
simulated discharge to surface water drainage.
Discharge by water supply wells was included in the model by assuming that a well is
located at each symbol designating a structure on Figure 3, and that all such wells pump
at a constant rate of 390 gallons per day (gpd) (130 gpd/bedroom x 3
bedrooms/structure). All wells were assumed to be completed in the bedrock and PWR
units (Layers 2 and 3) to a total depth of 250 ft below land surface. These wells were
included in the models both for calibration runs and for the depth to water analyses.

7.1.6. Water Levels and Flow Directions
Based upon experience in similar hydrogeologic systems, the configuration of the water
table in the conceptual model is assumed to be principally controlled by topography
(Toth, 1963). Seasonal perched water tables may occur locally where fine-grained soils
exist, but the zone of permanent saturation occurs begins in the lower part of the saprolite
and lower units. Based upon the results of GeoprobeTM borings and field water level
measurements in piezometers in November 2005, the water table beneath upland areas
occurs at depths of greater than approximately 20 feet. Six of the piezometers were dry
following installation and no wet zones were encountered during boring installation,
indicating that the water table during extended periods of low precipitation is below the
top of the P WR.
There is not a sufficient density of piezometers wells to prepare observed potentiometric
maps for the site. The best representation of the configuration of the water table and
groundwater flow directions results from simulation with a calibrated groundwater flow
model that can be shown to replicate observed water levels at available measurement
points. Figure 10 shows the simulated steady state water table computed with the
calibrated groundwater flow model.
7.2. Groundwater Flow Model
To assess the reasonableness of the conceptual hydrogeologic model for the area that
includes the Sunset Pointe property,' and to assess the likely depth to the water table under
the drip irrigation area under full irrigation conditions, a three-dimensional groundwater
flow model was constructed. The lateral boundary of this model is shown on Figure 1.
All model calibration and analysis runs utilized steady state conditions.
7.2.1. Purpose
The groundwater flow model was constructed for the following purposes:
• To assess the reasonableness of the conceptual model for the area by generation
of steady state expected water table configurations in and around the Sunset
Pointe property; and
To assess areas of proposed drip irrigation area where the depth to the water table
under design application rates may be less than two (3) feet.
7.2.2. Model Construction
The model was constructed using MODFLOW, a public domain computer code
developed and maintained by the U.S. Geological Survey. The model was constructed,
run, and the output evaluated using the Groundwater Modeling System (GMSTM) which
is a commercial modeling shell constructed for the U.S. Department of Defense by the
Environmental Modeling Systems Laboratory at Brigham Young University and
distributed and maintained by Ems-i.
21

The project database and GIS were used to facilitate both the preparation of datasets for
the groundwater flow models and to analyze output from the models. All maps included
in this report have been prepared using the project GIS and the integrated GIS capabilities
of GMS. Figure 6 shows the sources of data used to construct the necessary datasets for
the groundwater flow models.
7.2.2.1. Computational Grid
The model was constructed by assigning values of the parameters described in the
following sections to a finite -difference computational grid. A uniform 50 ft x 50 ft finite
difference grid comprising 321 rows and 396 columns was used to cover the modeled
area. The vertical boundaries of the three layers in the conceptual model were assigned
by using the elevation surfaces of the top of each a described in the conceptual model.
Figure 7 shows the configuration of the layer surfaces along representative west -to -east
and south to north sections.

7.2.2.2. Boundary Conditions
Drain boundaries were assigned along all drainages. The elevations of the drains were
assigned to be 4 feet below .the average elevation of the land surface for each cell. The 4
feet elevation difference was based upon field reconnaissance to assess the degree to
which streams were incised below the surrounding topography. This boundary condition
allows water to drain from the system via surface drainage if and when the water table
rises to the level of the drain. Drain conductance was set to a value of 1 ft2/day/ft to
assure adequate hydraulic connection between drains and the groundwater system.
Sensitivity analyses were used to assess the importance of drain conductance as discussed
in Section 7.2.3.
No -flow boundaries were assigned to all external model boundaries because these
boundaries were selected to coincide with topographic boundaries, which have been
found to generally coincide with groundwater flow divides. A no flow boundary
condition was assigned to the bottom of Layer 3. Figure 8 shows Boundary Conditions
used for the groundwater flow model.
High Rock Lake and the two upland ponds shown on Figure 8 were simulated using the
River boundary condition. The water level for the river boundary condition for High
Rock Lake was set at the mean pool elevation of 624 feet (U.S.G.S Southmont 7.5 minute
Quadrangle). The bottom elevation of High Rock Lake was set at a constant elevation of
615 feet, and the bottom conductance was set at 10 ft /day/ft. The water level for the
upland ponds was set at the elevation determined from the DEM discussed previously.
The bottom elevations for the upland ponds was set at 4 feet below the water level, and
the bottom conductance was set at 10 ft2/day/ft.
The existing wastewater treatment system includes a wet weather storage reservoir that
occupies approximately 1.05 acres and is excavated to a depth of approximately 10 to 15
ft below grade (DWG_to_Grid.dwg , Peidmont Development Associates, personal
communication, 2005). Because this reservoir is assumed to include a very low
permeability liner this reservoir was not included in the groundwater model.

7.2.2.3. Recharge and Discharge
The initial rate of steady state recharge applied was a constant rate of 8.4 inches per year.
As discussed in the conceptual model section, this rate was reduced by 50% to 4.2 inches
per year for model calibration because of the effect of the current drought conditions in
the region, and as a result of sensitivity analyses. Analyses to assess the potential for the
development of a water table shallower than three feet used a recharge rate of 8.4 inches
per year for all areas not occupied by the drip irrigation system.
Discharge from water wells within the model boundary that are assumed to supply
individual residences within the modeled area was simulated using a steady state
discharge of 390 gallons/day/well. This rate is considered conservative, and it is not
known if all residences are serviced by an individual well. Private well pumpage was
included to demonstrate that the effect of such wells, if they exist on the flow field
affected by the irrigation area is not insignificant:
7.2.3. Model Calibration and Sensitivity Analysis
The model. was calibrated by comparing the simulated steady state head to the available
water levels measured .on November 28, 2005 in the piezometers as shown in Table 3.
The only parameter that was varied in the model calibration was the. hydraulic
conductivity of layers 1, 2, and 3.
A combination of manual calibration and least squares fitting using the Parameter
Estimation (PEST) component of GMSTM was used to achieve an acceptable degree of fit
between simulated and observed water levels as measured by a visual plot of one versus
the other and multiple statistical measures as shown in Figure 9. The depths of the five
dry piezometers are also included in Figure 8 to illustrate that the simulated water level at
these locations is a an elevation lower than the top of the PWR.
The hydraulic conductivity for layers 1 and 2 was increased to 2.7 ft/day and the
hydraulic conductivity of Layer 3 was increased to 0.0025 ft/day from the initial
estimated values to achieve an acceptable fit. These increases are considered reasonable
because values of hydraulic conductivity at the scale used for the model grid are typically
5 to 10 times larger than values determined by slug tests in small diameter wells or
piezometer because of the effects of fractures and higher permeability weathered zones.
Figure 10 shows the calibrated water table elevation for the modeled area.
Sensitivity analyses were performed to demonstrate the effect on the goodness of fit to
ranges in parameters varied during model calibration and to varying rates of recharge.
Table 5 documents the results of these analyses. The cells highlighted in cyan in Table 5
show the value of the parameter varied during each sensitivity run while holding other
parameters constant.

7.3. Groundwater Flow Model Application
The calibrated flow model was used to assess the potential for the development of water
conditions at depths less than three feet.
7.3.1. Simulated depth to water beneath drip irrigation area
The groundwater model was used to assess the likely depth to water beneath drip
irrigation area. The requirements of 15A NCAC 2H .0200 require the water table beneath
drip irrigation area to at all times be greater than one foot, and if between one and 3 feet,
that a demonstration be made that groundwater quality is not _or will not be adversely
affected.
Initial. recharge under the drip irrigation area was simulated by applying the average
annual drainage rate of 5.25 inches/month in/week from the S&ME water balance model.
The average recharge rate applied outside the drip irrigation area was equal to the average
annual rate under normal climatic conditions of 8.4 inches/year (0.16 inches/week)
discussed in section 7.1.4. All groundwater model analyses were steady state (non time -
varying).
The initial recharge rate under the drip irrigation area resulted in significant portions of
the area having a water table shallower than 3 feet. Consequently, the recharge rate was
reduced in the irrigation area until only one small area remained with a simulated depth
to the watertable between 2 and 3 feet as shown in Figure 10.
7.3.2. Revised Water Balance
As discussed in the previous section, recommended drainage rate to minimize the
likelihood of the permanent watertable rising to within three feet of the land surface is 3.0
inches/month. The initial water balance prepared by S&ME used 5.25 inches/month.
Consequently, the water balance was revised using this lower drainage value. The
revision is included as Attachment D to this report. Using assumptions and approaches in
the revised water balance that have been used as part of multiple previously approved
non -discharge permit applications, the resultant wet weather storage requirements are
essentially the same as in the S&ME water balance. The recommended average annual
hydraulic loading rate from the revised water balance is 40.0 inches/year, compared to
the 44.03 inches per year in Appendix III of the S&ME report.

8. Conclusions
A defensible conceptual hydrogeologic model of the areas including the proposed drip
irrigation area has been constructed using available information from public domain
sources, field investigations, and tests by S&ME. The conceptual model developed of
subsurface geology and hydrogeology was based upon that previously developed and
used in hydrogeologic reports in support of non -discharge permits for sites in similar
geologic and hydrologic settings. Field data collected by Eagle Resources and by S&ME
substantiate this model.
At the time of field investigations in November 2005, over 20 feet of unsaturated material
is present beneath the irrigation field above the PWR. The material above the PWR is at
least 25 and as much as 35 feet deep beneath the sprayfields based upon depths to refusal
in 8 GeoprobeTM borings.
A three-dimensional groundwater flow model has been constructed and successfully
tested against available measured groundwater level measurements. ' The simulated
groundwater flow patterns are consistent with the conceptual model. Consequently the
model can reliably be used to assess the likely average water table configuration and
depth to water table under conditions where irrigation is applied to the existing and
expanded drip irrigation area.
Initial hydraulic conductivity values used in the simulation model are based upon field
'tests, and an acceptable model calibration was achieved by increasing the initial estimates
by a factor of 10. Model values of hydraulic conductivity are typically are 10 to 20 times
larger than values determined by slug tests in small diameter wells or piezometer because
of the effects of fractures and higher permeability weathered zones. Recharge under pre -
irrigation conditions was not adjusted during model calibration, but was set at 50% of the
normal expected values because of the documented extended drought conditions in the
region.
Based upon the results of this study, the recommended drainage rate beneath the drip
irrigation area to minimize the likelihood of the permanent watertable rising to within
three feet of the land surface is 3.0 inches/month. The S&ME water balance was revised
using this lower drainage value and is included as Attachment D, to this report. The
resultant wet weather storage requirements are essentially the same as in the S&ME
water balance. The recommended average annual hydraulic loading rate from the revised
water balance is 40.0 inches/year, compared to the 44.03 inches per year in Appendix III
of the S&ME report.

Water Balance and Wet -Weather storage
Analyses
Revised to Reduce Potential for Groundwater Mounding
Sunset Pointe at High Rock Lake
Rowan County, North Carolina
December 1, 2005
42

1. Introduction
This water balance report updates the water balance report prepared by Soil and Material
Engineers (S&ME) for the Sunset Pointe development (S&ME, 2005)
This work was performed by Eagle Resources, P.A. under contract to High Rock Lake
Development, LLC.
1.1. Purpose
This water, balance study has been completed in support of the non -discharge permit as
required by 15A NCAC 2H .0200, and conforms to the criteria outlined in 15A NCAC
2H .0219(k)(1)(A)(vii) for reclaimed water.
The purpose of the water balance study is to provide recommended volume for storage of
reclaimed water when irrigation is not possible or desirable during wet weather periods
and the recommended hydraulic loading rates based upon the hydraulic characteristics of
sprayfield soils.
1.2. Disclaimer
Some analyses contained in this report relied upon soils and other data and information
provided by others. Eagle Resources P.A. makes no representations regarding the
completeness, accuracy and reliability of that data and information.
2.. Data Sources
The following data sources were used for this report:
• S&ME, September 2005, Soil Scientist/Agronomist Report Proposed Sunset
Pointe Development Reclaimed Water Irrigation Systems, Rowan County, NC.
• Eagle Resources, 2005. Hydrogeologic Study for Sunset Pointe at High Rock
Lake.
• Site layout draft drawings provided by Piedmont Design Associates.
• Wet -weather storage reservoir surface 'areas and design volumes from drawings
provided by S&ME.
• Projected reclaimed water flows provided by S&ME.
• Daily station climatic data including precipitation, evaporation, , snowfall,
minimum and maximum air temperature, and solar radiation for the Greensboro -
Piedmont -Triad Airport climatic station located 38 mules north of the site, period
of record used: January 1930 through December 2004.

Precipitation data used by S&ME was used for the revised water balance. However, the
revised water balance accounted for surface runoff and used the Preistley-Taylor equation
to compute Potential Evapotranspiration (PET) as discussed below.
2. 1. Water Balance Equations
Water balance calculations were performed using the following equation:
St = St-1 + [ Inflowt ] - [ Outflowt ]; or
St=Sw+[Qt *at,+AR. PCPs/12]—[IA+AR.EVPt /12] (1)
Where: St = Storage required at the end of month t, Ac-Ft;
St-1 = Storage required at end of previous month, Ac-Ft;
AR = Surface area of area draining to all storage cells, Ac;
PCPt Precipitation during month t, inches;
Qt = Flow of reclaimed water, Ac-Ft/day;
At = time between month t and t- 1, in days
= no of days for each month;
IA = Allowable irrigation during month, ac-ft
= Ax * [(PETt *CCt ) + SROt + GWQxt - PCPt] / 12;
Ax = Total sprayfield area, acres;
EVPt = Evaporation from free water surface during month t = 0.6 * PET,
PETt = Potential Evapotranspiration for month t, inches;
CCt = Crop Coefficient for month t, = 0.80 for all months;
SROt = Surface Runoff for month t, inches; and
GWQxt = Drainage to groundwater for Soil Area x during month t, inches.
1 a)
inches;
Equation 1 was solved using Microsoft Excel® spreadsheet with at least two annual
cycles that demonstrated a convergent solution to wet weather storage requirements.
2.1.1. Climate and Runoff Data for Water Balance
Climatic data from the Greensboro -Piedmont -Triad airport climatic station was used the
water balance. J
2.1.1.1. Precipitation (PCP)
Monthly precipitation was taken from the Appendix III of the S&ME Report.
2.1.1.2. Surface Runoff (SRO)
Because the precipitation used, for the. wet weather storage water balance calculations
uses the 80"' percent wettest condition, the surface runoff used should also reflect the 8011'
percent wettest condition. Consequently, the average monthly surface runoff values were
computed using 20% of the monthly 80a' percentile wettest precipitation discussed above.
44

This value is conservative compared to measured rainfall runoff ratios for North Carolina
watersheds published by Lu, et.al, (2003, Table 1, p. 889). Table 1 shows values for
three Piedmont watersheds in North Carolina.

2.1.1.3. Potential Evapotranspiration (PET)
PET was calculated using the Priestly -Taylor equation which is a simplification of the
Penman energy balance equation. The Penman Equation accounts for the balance
between radiant and sensible heat and the loss of latent heat by advection (wind). The
Priestly -Taylor equation modifies the Penman equation by ignoring the advective term
and by multiplying the remaining energy term by constant (aPET = 1.28) to estimate Ep
from climatic data for conditions when the general surroundings are wet or humid:
PET = .CEP = aPET S (Rn — G).
S+y
Where A = latent heat of vaporization of water,
Ep = potential water vapor flux density,
s = slope of the saturation vapor density curve,
y = thermodynamic psychrometric constant,
R„ = net radiative flux density, and
G = sensible soil heat flux density.
By ignoring the advective (wind) term in the Penman equation, and using aPET, to
account for humid conditions expected in sprayfield environments present in in-
frequently mowed grass and mixed forests, the Priestly -Taylor Equation is the most
applicable to the Sunset Pointe project for purposes of computing the water balance.
Several recent publications support the use of the Priestly -Taylor Equation for sites in
North Carolina, and in particular, the Piedmont area.
The North Carolina State Climate Office maintains the on-line CRONOS database to
assist the agricultural industry in determining Potential ET using hourly and daily data
collected at stations throughout North Carolina. This agency uses both the Penman -
Monteith and the Priestly -Taylor equations to compute PET. Puryear, et.al. (2004)
concluded that the Priestly -Taylor equation best represented measured PET values when
using data sites across North Carolina. Lu, et.al. (2003) concluded in a study 4 39
watersheds across the southeastern US, including 12 in North Carolina that " ...the
Priestley and . Taylor [sic], Turc, and Hamon methods had the highest potential for
regional applications in the southeastern United States."

2.1.1.4. Precipitation on and Evaporation from Storage Reservoir
Surfaces
The wet -weather storage reservoir and the required five-day upset pond will be
constructed such that no surface drainage will occur into them: However, the water
balance requires the accounting of precipitation falling on the maximum area of these
reservoirs and of evaporation from the free water surface in the reservoirs when they
contain reclaimed water. The combined surface area used for the wet weather storage
reservoirs is estimated at 1.05 acres based upon drawings provided by Piedmont Design
Associates.
2.1.2. Soils and Drainage (GWQ) for Water Balance -
As discussed in the Hydrogeologic Report, the recommended drainage rate to minimize
the likelihood of the permanent watertabie rising to within three feet of the land surface is
3.0 inches/month. The initial water balance prepared by S&ME used 5.25 inches/month.
2.1.3. Design Reclaimed Water Discharge
The design flow rate of 75,000 gallons per day was provided by S&ME (Appendix III).
2.2. Monthly Water Balance Analysis
The revised convergent wet weather storage requirement calculation for Sunset Pointe is
included at the end of this Attachment. The wet weather storage requirements are 3.7
million gallons (MGal) or 49 days for a design flow of 75;000 gpd. The revised average
annual hydraulic loading rate is 37.33 inches per year, which is slightly less than the
40.27 inches per year in the S&ME water balance.
3. Conclusions
This report presents a revised monthly water balance analysis used to design wet weather
storage for the Sunset Pointe reclaimed water and irrigation system. The storage analysis
is based upon the 80d' percentile wettest condition (combination of precipitation minus
losses from evapotranspiration, runoff, and drainage to groundwater). The revised water
balance used a drainage rate of 3.0 inches per month instead of the 5.25 inches per month
used in the initial water balance by S&ME.
The wet weather storage requirements are 3.7 million gallons (N4Gal) or 49 days for a
design flow of 75,000 gpd. This is slightly less than the 3.9 MGal or 52 days reported in
Appendix III of the S&ME report.
The revised average annual hydraulic loading rate is 37.33 inches per year, which is
slightly less than the 40.27 inches per year in the S&ME water balance.

Facility: Sunset Pointe Subdivision
Rowan County, N.C.
Enclosed you will find the report for the annual compliance inspection that I conducted at the referenced
facility on October 28, 2009. The report should be self-explanatory.
Clearing the underbrush has helped improve the operator's ability to maintan the drip lines in the wooded
application areas. Now that the vegetation is under control, a periodic clean-up schedule should be
instituted to keep those fields in good condition. The area around the lagoons needs to be maintained in
the same manner.
Should have questions, please call me at 704/235-2183 or contact me via email at
[e-mail].

Hey Dan,
As I mentioned to you last week, I was going to be with Peggy Finley, DWQ regional specialist, and
Donald Munday, Piedmont Design, at another treatment facility this past Monday. We discussed
her visit and inspection to Sunset Pointe. You will probably get a letter from her and/or Donald
concerning getting the rest of the system drip area completed as per the permit requirements.
Basically she said the following concerning the current state of the facility:
1. The additional some 16 acres that were clear cut do need to be planted with the specified tree
crop to comply with the issued permit.
2. The undergrowth that is growing in all of the 34 acres needs to be controlled by cutting and/or
herbicide spraying where proper inspections and maintenance can be performed. We all feel that
once the growth has been killed out or controlled effectively the cost of maintaining should go down
with the tree canopy that is there. Once under control, it may only take cutting and/or spraying
once or twice a year to keep it controlled. My advise is to get it hand cut now while dormant and
then have it all sprayed in the early Spring just when the new.growth starts. I think you will get
the best results that way.
3. The phone line must be active again. The telemetry is required for that size of system to insure
environmental protection while the operator is not on site. As you know we are only on site once a
week. With a phone line we can monitor the system remotely 24/7 and various alarms can notify
us if there is a failure of equipment.
Thank you for your attention on these matters and if you have specific questions you may want to
contact Peggy or Donald directly and address them.

RE: Surface Irrigation Inspection Report
Permit No. WQ0029635
Facility: Sunset Pointe Residential Subdivision
Rowan County, N.C.
Enclosed you will find the report for the annual compliance inspection that I conducted on October 21,
2008. The report should be self-explanatory but one finding requires emphasis.
The underbrush in many areas of the pine forest is significantly overgrown. This situation makes it
difficult for the operator to evaluate the condition of the drip lines. On the other hand, the clearcut areas
and the drip fields with no tree cover remain essentially bare. This encourages soil erosion and possibly
premature degradation of the irrigation lines. Your permit requires that a suitable year-round cover crop
be provided and maintained. The underbrush. needs to be removed or cut back and a- regular
maintenance schedule must be implemented. Preparations must be made to begin planting pine
saplings in the treeless areas of the designated irrigation areas.
Should you have any questions, please feel free to call me at 704/235-2183 or contact me via email at:
