1.
Attachment to Cover Letter
Comments on the Highway 150 WWTP Draft Permit were received from Aqua North
Carolina (The Permittee) and C. David Merryman (The Catawba Riverkeeper).
Comments from both parties are stated below and Division responses follow in bold
print.
1. The Permittee requested item 5., which requires adherence to the guidelines specified
in the NC DWQ/ NPDES Unit/ EAA document, be removed from Section A.(3.) a.).of
the permit.
Item 5 has been removed from Section A.(3.) a) in the Final Permit. Whether the
statement is in the permit or not, the Permittee will be required to adhere to the
EAA guidelines if a future expansion is requested.
2. The Permittee requested that the domestic flow from the projected population growth
in the amount of 52,500 GPD be included in the expanded flow justification volume.
Flow projections for Non -Municipal facilities are based on design projections.
Aqua's flow justification included facility designs for population growth in the
Ridgetop Rd. Development and the Lake Norman Promenade. The flow limit on
the expansion will remain at 0.225 MGD in the Final Permit.
3. The Permittee requested that the frequency for fecal coliform monitoring be reduced
from seven days per week to three days per week or less.
Similar domestic wastewater treatment facilities located on Lake Norman have
had their fecal coliform monitoring reduced to 3 days per week and once per
week. Given the continued public concern over the issuance of this permit an
initial reduction in monitoring to 3 days per week was put in the Final Permit.
4. The Catawba Riverkeeper Foundation (CRF) recommended that the permit renewal be
denied or continued while: a) consolidation proceedings are pursued or b) the
permittee actively implements other treatment and disposal strategies that eliminate
this discharge directly into Lake Norman.
a) Consolidation of the Aqua facility with the local municipality is currently not a
viable option. Plans for the Town of Mooresville's WWTP expansion are
tentative and no connection is available to the Permittee. The Division supports
regionalization of WWTPs and will encourage Aqua and the local municipalities
to work together.
b) As part of the permit application Aqua was required to demonstrate that the
WWTP was the best engineering alternative for disposal of the existing
wastewaters. Aqua adequately justified the WWTP alternative and the Division
does not see a reason to deny this permit.

5. The CRF is concerned that the Division does absolutely nothing to limit nutrient
loading (TN and TP) from the facility at 0.1 MGD or at the proposed expansion to
0.225 MGD.. CRF requests the addition of TN and TP loading limits in the permit.
Administrative Code 15A NCAC 2B .0500 specifies quarterly monitoring for TN
and TP for domestic WWTP facilties of this size. Lake Norman has not been
classified as nutrient sensitive waters and the nutrient loading from a facility of
this size and type is not expected to be significant. There is no justification for
TN and TP loading limitations at this time. Quarterly monitoring was added to
the draft permit for TN and TP and will remain in the Final Permit on both
effluent pages.
b. CRF requests that an expansion of discharge to Lake Norman at this location be
subject to public notification and comment. In addition, CRF requests removal of
Section A.(2) of the draft permit which allows for an expansion to 0.225 MGD.
The draft permit for the Hwy 150 WWTP, which included the expansion
documented in Section A.(2.), was public noticed on June 9, 2011 followed by a 30
day public comment period. The expansion was subjected to public notification
and comment and will remain in the Final Permit.
7. CRF requests that Hwy 150 WWTP test annually for PCBs in its effluent and in the
sediments and fish residing in Lake Norman near its outfall.
The Hwy 150 WWTP receives sanitary wastewaters from residential and
commercial facilities in its service area. Runoff from gas stations or performance
shops should not be included in any wastewaters being discharged to the
treatment plant. There is no evidence or documented source of PCBs being
discharged to the WVVTP. NC Administrative Code does not require 100%
domestic sanitary wastewater treatment plants to monitor for PCBs. Testing for
PCBs in the effluent, sediment and fish is not justified and will not be required in
the Final Permit.
8. CRF believes the dilution study submitted by the applicant shows the potential for
violations of the public's right to clean recreational waters with recognition that air in
the effluent causes effluent to surface posing a threat to public.
The Hwy 150 WWTP discharges treated wastewater in batches of 1010 gallons
throughout the day. On the average, the facility discharges 23,000 gallons per
day. A review of the facility's Discharge Monitoring Reports shows that no
permit limitation violations occurred from 2007 through 2010. A dilution study
on Hwy 150 WWTP's discharge showed that because the wastewaters are
released a batch at a time, the air collected in the effluent pipe between batches
will cause the effluent to rise and will result in increased mixing due to turbulence
caused by the air. Note, the Division will sometimes require permittees to install
air diffuses so increased mixing is acquired. The treated wastewaters from the
Hwy 150 WWTP and the increased mixing that occurs as each batch is released is
not expected to pose any threat to the public.

History
On Nov. 21, 2002, Judge Conner recinded NPDES Permit No. 0074900 held by Hydraulics Ltd.
On June 6, 2003 the NPDES Committee affirmed the recission upon the following conditions:
(1) from the date of the signing of this Final Agency Decision, the recission is stayed and the
facility may continue to operate and discharge under the 2000 permit for one year or, longer if
necessary, until the decision is made on the application, pursuant to the procedures in G.S.
143-215.1, to issue or deny a new NPDES Permit; (2) The 0.10 MGD treatment capacity and
effluent limits specified in the 2000 permit are applicable while the facility operates as provided
under this final decision; (3) the applicant, in conjunction with an application for a new permit,
shall submit an analysis of the `practicable waste treatment and disposal alternatives" to the
surface water discharge; and (4) the applicant for the new permit shall perform and coordinate
with the Department's DWQ any water quality modeling and impact analyses deemed by the
Division Director as necessary for a complete application for a new permit.
Treated wastewater from the Hwy 150 WWTP enters a 5000 gallon dechlorination tank prior to
being pumped to Lake Norman. When the tank fills to about 3500 gallons, 1010 gallons are
pumped out the force main with a 360 gpm pump. This process takes about 2.8 min leaving
2490 gallons remaining in the tank. After the 1010 gallons are discharged, the pump shuts off
and the tank begins to be refilled. As required, on Dec. 2, 2003 CH2Mhill submitted a "Dilution
Study' for Hydraulics, LTD Highway 150 WWTP". Some information from the report is
summarized below.
NC0004944 NPDES Fact Sheet
Page I

The data indicate that there is a significant amount of dilution with the
average dilution within 25 feet of the outfall exceeding 100.1. All model
runs indicated dilution in excess of 40:1 a short distance from the
outfall. The dye study indicated that at a depth of 38 - 40 feet within a
25 foot radius, the average dilution was 365 with a dilution ranging from
6 to 5290. Based on this average dilution, at an effluent BOD
concentration of 15 mg/L, the BOD in the surrounding water would be
0.04 mg/L if there was no BOD in the lake.
On June 2004 Aqua North Carolina acquired Hydraulics, LTD. Correspondence and phone
memos during that period indicate many discussions on the possibility of connecting Highway
150 to the Town of Mooresville's WWTP. WWTP expansions were under consideration and the
possibility of connecting the WWTP seemed likely. At some point, the WWTP expansions being
considered did not include the Highway 150 WWTP service area and the possibility of the
connection became infeasible.
By 2010 the possibility of connecting Hwy 150 to the POTW was no longer a consideration. On
April 1, 2010 DWQ met with Aqua NC in the Mooreville Regional Office and requested Aqua to
submit a revised EAA and application for the Highway 150 WWTP.
Wasteload Allocation Summ
An EAA was submitted on June 21, 2010 and revisions in response to DWQ comments were
received on Dec. 1, 2010. Flow justifications which were of primary concern in the 2000 permit
continued to be a point of disagreement in the application. Cresent Resources, originally the
primary developer and wastewater source to the Highway 150 WWTP, was no longer a
contributing factor. Cresent Resources had agreed to give up a 400,000 gpd discharge permit to
Lake Norman in exchange for Hydraulics Ltd. (Hwy 150 WWTP) agreeing to serve developments
that might occur on their remaining land holdings in the area. Out of the estimated 238 homes
expected to be developed by Cresent Resources only 11 (cited as Ridgetop Rd. Development) are
proposed to be connected to the Hwy. 150 WWTP in the EAA. Attached, in Table 1.01, are the
Flow Projections for the Highway 150 WWTP.
Flow Projections - Highway 150 WWTP
Existing buildings and developments underway account for 137,925 gpd.
Planned Commercial and residential developments account for 86,240 gpd.
Projected commercial and domestic growth account for 123,290.
The Total projected flow in the EAA is 347,455 gpd, however, Aqua NC is requesting a permit
for 300,000 gpd.
Letters from the planned commercial (Lake Norman Promenade) and residential (Lake
Promenade Condos and Ridgetop Rd.) developments were received, however, details on Lake
Promenade's development including the specific number of condominiumns, hotel capacity,
retail' shops, etc. were not submitted by the owner until May 6, 2011. Updated Local
Government Forms from the Town of Mooresville and Iredell County were received on April 13,
2011.
As identified in DWQ's Engineering Alternatives Analysis (EAA) Guidance Document flow
projections for Non -Municipalities are to be based on engineering design consideration and/or
projections rather than population projections. Therefore only the existing and planned
commercial and domestic flows can be accepted for approval in the EAA. This amount totals
137,925 gpd plus 86,240 gpd or 224,165 gpd. Since these numbers are estimates, this number
was rounded up to a flow limit of *0.225 MGD on the Effluent Limitations and Monitoring
Requirements expansion page.

Addendum to Fact Sheet 9/2011
Comments on the Highway 150 WWTP Draft Permit were received from Aqua North Carolina
(The Permittee) and C. David Merryman (The Catawba Riverkeeper). Comments from both
parties are stated below and Division responses follow in bold print.
1. The Permittee requested item 5., which requires adherence to the guidelines specified in the
NC DWQ/ NPDES Unit/ EAA document, be removed from Section A.(3) a.).of the permit.
Item 5 has been removed from Section A.(3.) a) in the Final Permit. Whether the.
statement is -in the permit or*not, the Permittee will be required to adhere to the EAA
guidelines if a future expansion is requested.
2. The.Pemuttee requested that the domestic flow from the projected population growth in the
amount of 52,500 GPD be included in the expanded flow justification volume.
Flow projections for Non -Municipal facilities are based on design projections. Aqua's
now justification included facility designs for population growth in the Ridgetop Rd.
Development and the Lake Norman Promenade. The flow limit on the expansion will
remain at 0.225 MGD in the Final Permit.
3. The Permittee requested that the frequency for fecal coliform monitoring be reduced from
seven days per week to three days per week or less.
Similar domestic wastewater treatment facilities located on Lake Norman -have had their
fecal coliform monitoring reduced to 3 days per week and. once per week. Given the
continued public concern over the issuance of this permit an initial reduction in
monitoring to 3 days per week was put in the Final Permit.
4. - The Catawba Riverkeeper Foundation (CRF) recommended that the permit renewal be
denied or continued while: a) consolidation proceedings are pursued or b) the permiteee
actively implements other treatment and disposal strategies that eliminate this discharge directly
into Lake Norman.
a) Consolidation of the Aqua facility with the local municipality is.currently not a viable
option. Plans for the Town of Mooresville's WWTP expansion are tentative and no
connection is available to the Permittee. The Division supports regionalization of
WWTP's and will encourage Aqua and the local municipalities to work together.
b) As part of the permit application Aqua was required to demonstrate that the
WWTP was the best engineering alternative for disposal of the existing wastewaters.
Aqua adequately justified the WWTP alternative and the Division does not see a reason
to deny this permit.
NCO004944 NPDES Fact Sheet
Page 4

5. The CRF is concerned that the Division does absolutely nothing to limit nutrient loading (TN
and TP) from the facility at 0.1 MGD or at the proposed expansion to 0.225 MGD, CRF
requests the addition of TN and TP loading limits in the permit. .
Administrative Code 15A NCAC 2B .0500 specifies quarterly monitoring for TN and TP
for domestic WWTP facilties of this size. Lake Norman has not been classified as
nutrient sensitive waters and the nutrient loading from a facility of this size and type is
not expected to be significant. There is no justification for TN and TP loading
limitations at this time. Quarterly monitoring was added to the draft permit for TN and
TP and will remain in the Final Permit on both effluent pages.
6. CRF requests that an expansion of discharge to Lake Norman at this location be subject to
public notification and comment. In addition, CRF requests removal of Section A.(2) of the
draft permit which allows for an expansion to 0.225 MGD.
The draft permit for the Hwy 150 WWTP, which included the expansion documented in
Section A.(2.), was public noticed on June 9, 2011 followed by a 30 day public comment
period. The expansion was subjected to public notification and comment and will
remain in the Final Permit.
7. CRF requests that Hwy 150 WWTP test annually for PCBs in its effluent and in the
sediments and fish residing in Lake Norman near its outfall.
The Hwy 150 WWTP receives sanitary wastewaters from residential and commercial
facilities in its service area. Runoff from gas stations or performance shops should not be
included in any wastewaters being discharged to the treatment plant. There is no
evidence or documented source of PCBs being discharged to the WWTP. NC
Administrative Code does not require 100% domestic sanitary wastewater treatment
plants to monitor for PCBs. Testing for PCBs in the effluent, sediment and fish is not
justified and will not be required in the Final Permit.
8. CRF believes the dilution study submitted by the applicant shows the potential for
violations of the public's right to clean recreational waters with recognition that air in the
effluent causes effluent to surface posing a threat to public.
The Hwy 150 WWTP discharges treated wastewater in batches of 1010 gallons
throughout the day. On the average, the facility discharges 23,000 gallons per day. A
review of the facility's Discharge Monitoring Reports shows that no permit limitation
violations occurred from 2007 through 2010. A dilution study on Hwy 150 WWTP's
discharge showed that because the wastewaters are released a batch at a time, the air
collected in the effluent pipe between batches will cause the effluent to rise and will
result in increased mixing due to turbulence caused by the air. Note, the Division will
sometimes require permittee's to install air diffuses so increased mixing is acquired. The
treated wastewaters from the Hwy 150 WWTP and the increased mixing that occurs as
each batch is released is not expected to pose any threat to the public.

History
On Nov. 21, 2002, Judge Conner recinded NPDES Permit No. 0074900 held by Hydraulics Ltd.
On June 6, 2003 the NPDES Committee affirmed the recission upon the following conditions:
(1) from the date of the signing of this Final Agency Decision, the recission is stayed and the
facility may continue to operate and discharge under the 2000 permit for one year or, longer if
necessary, until the decision is made on the application, pursuant to the procedures in G.S.
143-215.1, to issue or deny a new NPDES Permit; (2) The 0.10 MGD treatment capacity and
effluent limits specified in the 2000 permit are applicable while the facility operates as provided
under this final decision; (3) the applicant, in conjunction with an application for a new permit,
shall submit an analysis of the "practicable waste treatment and disposal alternatives" to the
surface water discharge; and (4) the applicant for the new permit shall perform and coordinate
with the Department's DWQ any water quality modeling and impact analyses deemed by the
Division Director as necessary for a complete application for a new permit.

Comments on the Highway 150 WWTP Draft Permit were received from Aqua North Carolina
(The Permittee) and C. David Merryman (The Catawba Riverkeeper). Comments from both
parties are stated below and Division responses follow in bold print.
1. The Permittee requested item 5., which requires adherence to the guidelines specified in the
NC DWQ/ NPDES Unit/ EAA document, be removed from Section A.(3.) a.).of the permit.
Item 5 has been removed from Section A.(3.) a) in the Final Permit. Whether the

guidelines if a future expansion is requested.
2. The Permittee requested that the domestic flow from the projected population growth in the
amount of 52,500 GPD be included in the expanded flow justification volume.
Flow projections for Non -Municipal facilities are based on design projections. Aqua's
flow justification included facility designs for population growth in the Ridgetop Rd.
Development and the Lake Norman Promenade. The flow limit on the expansion will
remain at 0.225 MGD in the Final Permit.
3. The Permittee requested that the frequency for fecal coliform monitoring be reduced from
seven days per week to three days per week or less.
Similar domestic wastewater treatment facilities located on Lake Norman have had their
fecal coliform monitoring reduced to 3 days per week and once per week. Given the
continued public concern over the issuance of this permit an initial reduction in
monitoring to 3 days per week was put in the Final Permit.
4. The Catawba Riverkeeper Foundation (CRF) recommended that the permit renewal be

RE: COMMENTS ON DRAFT NPDES PERMIT NCO074900 FOR HWY 150 WWTP
Dear Ms. Grzyb,
Our purpose for providing comments on the Division of Water Quality's intent to renew the
NPDES permit for Hwy 150 W WTP in Itedell County, NC involves the protection of the Catawba
River at Lake Norman. Lake Norman serves numerous recreational uses and as a drinking water
supply for communities in the Catawba River basin. Furthermore, Catawba RIVERKEEPER®
Foundation (hereinafter CRF) has petitioned NC DWQ to reclassify Lake Norman to a HQW
because of its record of excellent water quality as reported by DWQ`. For these reasons, Catawba
Riverkeeper Foundation, Inc. seeks to halt the degradation of this body of water and safeguard the
recreational and drinking water uses of this waterbody by citizens. Therefore, CRF respectfully
submits these comments on behalf of the Catawba River, its watershed, and CRF members.
CRF is a non-profit environmental conservation organization and has been registered as a 501 (c)(3)
in North Carolina since 1997. CRF's mission is to advocate for the protection, enhancement and
enjoyment of the entire Catawba River watershed. With approximately 1200 members throughout
the 17 counties that span the Catawba River Basin in North Carolina, CRF is the only local river
conservation and advocacy organization focused solely on the protection and enhancement of the
Catawba River.
First and foremost, CRF does not believe DWQ should reissue NCO074900 to Aqua North
Carolina, Inc. because it allows a discharge into a lentic waterbody within the Catawba River basin
that exhibits excellent water quality, serves as a drinking water supply for thousands of North
Carolinians, supports millions of dollars in recreational revenues to our local and state economy
every year and dilutes infrequently with a mean retention time of 239 days for waters within the
CRF submitted a request for extension of the Public Comment period (July 8, 2011) and worked with DWQ staff
during the week of July 11-15 in order to review information submitted by the applicant in order to coalesce
comments submitted herein. It should be noted that the Division's website is not working on the date of submission -
July 18, 2011, making additional relevant information collecting more difficult as previously mentioned in the
extension letter.

reservoir, according to Duke Energy. Furthermore, CRF believes the dilution study submitted by
the applicant shows the potential for violations of the public's right to clean recreational waters with
recognition that air in the effluent causes effluent to surface which poses a viable threat to public
safety'.
Therefore, CRF recommends that this permit renewal be denied. CRF would be happy to discuss
our desires regarding this discharge with the Division and the applicant, and CRF could potentially
agree to a continuation of the existing discharge under NCO074900 while consolidation proceedings
are actively pursued and implemented with local municipal providers or while the permittee actively
implements other treatment and disposal/application strategies outlined in the environmental
documents submitted by the applicant that eliminate this discharge directly into Lake Norman.
PERMITMODIFTC 47YONS NEEDED
If the Division does not deny this permit request, CRF believes we retain the right to submit
additional comments regarding this permit renewal application.
To elaborate, Lake Norman exhibits oligotrophic water quality as indicated in several DWQ
documents. While the Division should be commended for its effotts within this draft permit to
limit NH3 as N, the Division does absolutely nothing to limit nutrient loading (Total Nitrogen and
Total Phosphorus) from this facility at 1.0 MGD or at the proposed expansion to 0.225 MGD.
Acting within the lentic ecosystem of Lake Norman, phosphorus plays a primary role as the limiting
nutrient to algal productivity and should therefore be limited within this permit and monitored
weekly to prevent any degradation of this waterbody. These nutrient limits are even more salient
with a request pending for a reclassification of Lake Norman to HQW. Not only would this permit
requirement provide better reporting and insight to the nutrient loading of Lake Norman, but this
addition would provide potentially undeniable assurances that Hwy 150 WWTP is limiting its
impacts on the nutrient loading of an oligotrophic waterbody.
With the Town of Mooresville currently investigating a WWTP discharge at a location in close
proximity to the outfall of the Hwy 150 WWTP, CRF believes the establishment of nutrient limits
and regular monitoring requirements for the Hwy 150 WWTP would provide security to the
owners/operators of the Hwy 150 WWTP should any nutrient anomalies develop with additional
discharges in the area.
Additionally, CRF believes an expansion of discharges to Lake Norman at this location should be
subject to public notification and comment. We believe this to be necessary because of the high
public use (drinking and recreation) of Lake Norman. Therefore, CRF believes A.(2.) of this draft
NCO074900 permit should be removed and not approved with this draft permit.

CRF believes that Hwy 150 W WTP should test for PCBs in its effluent and in the sediments and
fish residing in Lake Norman near its outfall during the annual priority pollutant analysis due to the
presence of gasoline stations and performance shops and suspension shops within its service area.
This suggested permit change and monitoring requirement would assure that Hwy 150 W WTP is
not contributing to a problem that has recently resulted in fish consumption advisories in the
Catawba River basin and the loss of use of River fish by North Carolinians.
Conclusion
For these reasons, CRF believes that the Division of Water Quality should not approve the draft
NPDES permit NCO074900 as proposed. The biological, chemical and recreational integrity of this
waterway should be protected and maintained with the implementation of this permit; and at this
time, CRF does not feel that the immediate renewal of NCO074900 would, in fact, do so.
The Division should not grant this pertnit renewal as proposed. Therefore, CRF requests that the
following modifications to the draft permit occur if discharge continues from NCO074900:
1. Addition of TN and TP loading limits to Section A(1).
2. Removal of Section A(2).
3. Effluent monitoring for PCBs during annual priority pollutant analysis.
4. PCB monitoring in sediment and fish near effluent discharge location in Lake Norman
during annual priority pollutant analysis.
5. Require public notification and comment period for any discharge expansion.

the NPDES permit for Hwy 150 W WTP in Iredell County, NC. If you have any questions, please
do not hesitate to contact us. Our address and phone number follows: Catawba Riverkeeper

This letter is in response to your letter dated June 8, 2011, which accompanied a copy of the subject
draft NPDES permit. In accordance with your letter, we are providing these comments to request the
revisions described hereto:
1. Section A (3), a) 5.
We request that this item be removed. The North Carolina Division of Water Quality
"Engineering Alternatives Analysis Guidance Document" is not a regulation. Inclusion of
this provision within an enforceable NPDES permit in effect would give the document the
weight of a regulation without due process and would preclude flexibility for consideration
of special conditions by the permittee or by the Division of Water Quality.
2. Step 2. Residential Population Projection, of the "Engineering Alternatives Analysis
Guidance Document" provides guidance for projecting expanding domestic growth based on
population projections. This is not limited to municipal flow projections. Table 1.01 of the
2010 updated Engineering Alternatives Analysis (EAA) includes projection for domestic
growth based on population growth in the amount of 52,600 GPD. This is a projection made
using a projected growth in the identified residential contributors (apartments, single family
homes and condominiums) corresponding to the projected 20-year population increase
(55%). This projected residential increase attributed to projected residential growth over the
20-year period, should be added to the 0.225 MGD currently identified in the draft permit for
future expansion. Hence, the permit should allow for expansion to 0.28 MGD.

3. The draft permit proposes fecal coliform monitoring seven days a week during the summer
months. This facility has established a long history of consistent compliance with fecal
coliform limits. Similar dischargers of treated domestic wastewater into Lake Norman (e.g.
Lake Norman 'Woods, NPDES NC0071528 and Camp Dogwood, NPDES NC0044253) are
only required to monitor fecal coliform weekly. This is consistent with the applicable
regulations. Seven day per week monitoring is excessive, unnecessarily burdensome and
inconsistent with the long, excellent compliance history at this facility.
Aqua North Carolina, Inc. is willing to accept three day per week monitoring of fecal
coliform during summer months. This is still much more frequent than is required of similar
dischargers into Lake Norman.
We appreciate the efforts of you and the Division of Water Quality staff in working to issue this
permit. We believe the changes we have requested are reasonable and justified. If you have any
questions, need any additional information or if there are any matters we should discuss, please
contact us.

Julie,
I have reviewed the draft permit and determined that the proposed discharge is not located sufficiently close to any
existing or known proposed public water supply intake so as to create an adverse effect on water quality. The DEH
concurs with the issuance of this permit provided the Permittee properly operates and maintains the facility; the Permittee
meets the stated effluent limits prior to discharge; and the discharge does not contravene the designated water quality
standards.

SUBJECT: Lake Norman Promenade
Dear Mr. Horne:
This letter is a follow up to our discussions regarding the plans under development of the property
referred to as Lake Norman Promenade. I appreciate you sharing a copy of the letter you
received from the state (dated September 3, 2010) and understand that the state has asked for
some additional information regarding this development.
The items of the proposed Lake Norman Promenade are as we discussed earlier, and the elements
we are planning to include as we proceed with plans for Lake Norman Promenade in the future.
Since the Highway 150 WWTP is the only logical existing alternative for wastewater treatment
for our development, it is our desire that we be allowed to connect to the WWTP when our
development is completed.
At this point, we have prepared the preliminary plans showing the proposed layout of the
buildings, etc. 1 have previously provided copies of these to you and you should feel free to share
these for the state's review as they requested in their letter. The current slow down in economic
conditions leaves uncertainty as to when the development will be completed but 1 would hope
that this will occur in the near future and certainly within the next twenty years, which is, as 1
understand, the period of time you are assessing.
In summary, the plans for developing the Lake Norman Promenade are in keeping with the
information we have discussed. It is important to the progress of this development and it is our
desire that we maintain the ability to connect to the Highway 150 WWTP.
We appreciate your efforts to maintain the available capacity in the WWTP to allow for our
development (should it occur) and the growth of this area.
Please do not hesitate to call me should you have any questions or need any additional
information.

RE: Lake Norman Promenade
Dear Mr. Horne:
The Lake Norman Promenade project is still on hold based on today's economic
conditions. It is not clear when conditions will improve and allow the project to
move forward but, the plans at this time include the 200 boat slips, with
condominiums (105 units), retail shops (33,000 SF), conference facility (60,000
SF) and hotel (150 rooms). The exact number of units and square footage may
vary, but based on preliminary planning this is our best estimate at this time.
Our client's intention would be to maximize the use of the property in a manner
illustrated in our schematic designs previously provided to you; however, this will
be driven by the market demand.
Please do not hesitate to call me should you have any questions.

Attachment A. Local Government Review Form
General Statute Overview North Carolina General Statute 143-215.1 (c)(G) allows input from local governments in the issuance
of NPDES Permits for non -municipal domestic wastewater treatment facilities. Specifically, the Environmental Management
Commission (EMC) may not act on an application for a new non -municipal domestic wastewater discharge facility until it has
received a written statement from each city and county government having jurisdiction over any part of the lands on which the
proposed facility and its appurtenances are to be located. The written statement shall document whether the city or county has a
zoning or subdivision ordinance in effect and (if such an ordinance is in effect) whether the proposed facility is consistent with the
ordinance. The EMC shall not approve a permit application for any facility which a city or county has determined to be
inconsistent with zoning or subdivision ordinances unless the approval of such application is determined to have statewide
significance and is in the best interest of the State.
Instructions to the Applicant: Prior to submitting an application for a NPDES Permit for a proposed facility, the applicant
shall request that both the nearby city and county government complete this form. The applicant must:
• Submit a copy of the permit application (with a written request for this form to be completed) to the clerk of the city and
the county by certified mail, return receipt requested.
• If either (or both) local government(s) fail(s) to mail the completed form, as evidenced by the postmark on the certified
mail card(s), within 15 days after receiving and signing for the certified mail, the applicant may submit the application to
the NPDES Unit.
• As evidence to the Commission that the local government(s) failed to respond within 15 days, the applicant shall submit a
copy of the certified mail card along with a notarized letter stating that the local government(s) failed to respond within the

Dear Ms. Grzyb:

This letter is in response to your request for additional information and changes to the updated
Engineering Alternative Analysis (EAA) that we provided dated June 17, 2010. This information
relates alphanumerically to the items listed in your letter.
Existing and Potential Flows
All projected flows are sufficiently documented. Review and reliance on actual DMR's can
not be used as the only means for projecting the potential future capacity requirements. Pier
16 was a former NPDES discharge facility that was approved and permitted by the North
Carolina Division of Water Quality (NC DWQ). This W WTP was replaced by a pump
station which conveys the existing and future wastewater flow from this area to the Highway
150 W WTP. The capacity used in the updated EAA for this pump station is the capacity for
which NC DWQ has issued approval and also, the approved capacity of the WWTP which it
replaced.
Similarly, the capacity used in the EAA for River Park is the capacity of the sewers and
pump station that NC DWQ approved for this construction. The sewers and pump stations
approved by NC DWQ and constructed in these areas were built for the future projected
growth of these areas. This is not going to correspond directly to existing flow rates while
portions of this service area remain less than fully developed.
We do not have nor do we have the means of providing plats, drawings of future buildings,
construction by the owners. This type information, if it exists, is not
DEC 0 12010
An Aqua America Company

available to Aqua North Carolina, Inc. nor do the Division of Water Quality's rules require
submission of such documents at this time.
Permits for sewer service to these areas were issued by NC DWQ, and the owners of the
properties served by these facilities relied on these permits in financing and constructing
their facilities. These applicants were under no obligation to document that other disposal
options were not available.
2. Please see the attached letter. The letter refers to a conversation with Ms. Derwort of the
Iredell County Health Department. Our engineer (J. Thurman Horne, P.E.) also spoke with
Ms. Derwort and she confirmed that she is not aware of any restriction or limit on the
number of seats Big Daddy's can have.
3. No. There is no requirement to measure wastewater flow from these individual contributors.
Current water usage would not be a reliable indicator for projecting potential future flows.
Many of these facilities are temporarily closed or experiencing a downturn in business due
to the economy. In addition, some owners have not fully developed their properties. The list
of dischargers was developed by inventorying what facilities are connected to the
wastewater system, identifying what the components of each such facility are (i.e. the
number of restaurant seats, number of bedrooms, etc.) and applying the appropriate unit
design flow estimates as available in state regulations and documents. For example,
although an apartment unit may be unoccupied at present, it may likely be occupied in the
near future and provision must be made to accept and treat the flow it will generate. This has
been done using the state's estimate of 120 gallons per day per bedroom.
4. This matter was discussed with the owner. The owner has confirmed that he chose to install
a sewer collection system for this development after an investigation by a soils scientist
concluded that on site disposal was not a viable option. The owner would obviously have
preferred the less costly option of an on -site disposal if this had been practical. NC DWQ
issued a permit for extension of service for Ridgetop Subdivision dated June 23, 2008. (See
Attached Wastewater Collection System Extension WQ0029530.)
Future Flows
5. Copies of the plans developed for the proposed Promenade development are attached.
Attached is a letter from Mr. Robert Johnson confirming that the owner wishes to be
served by the Hwy 150 WWTP and to confirm that the flow projections made in the EAA
are in accordance with their proposed development.
6. As noted in the EAA, the projected growth and future land use is substantiated by
reliance upon the projections provided in the "Iredell County 2030 Horizon Plan" and
"River Highway Corridor, Future Land Use", both of which have been developed by Iredell
County. The projected growth used in the EAA is consistent with the projected growth in
these documents. It should be noted that the "Iredell County 2030 Horizon Plan", which is
the source of future growth projections, was approved just a little over a year ago
(September 15, 2009.)
7. There is no information available that would allow us to be able to reliably predict a schedule
for when the build out of the WWTP may occur. This would be more difficult than reliably

predicting the recovery of the economy. We are making the best projections we can, using
information available and consistent with state guidance to project the growth likely to occur
over the next twenty years. Attempting to break this down further, without additional
information that is simply nonexistent is merely guessing and unsupported.
There are far too many variables and far too many property owners with their own
uncertainties as to when and to what extent any plans may move forward.
Alternatives
8. The projected flows contained in the EAA have been derived by reviewing existing flows
and projected future growth consistent with the guidance provided by the state. Connection
to the Town of Mooresville was evaluated but was determined to be impractical due to the
extreme additional cost for this option. The Town's capacity and/or willingness to accept the
flow therefore are moot issues.
Although the cost differential alone is demonstrated sufficiently to conclude that connection
to the Town of Mooresville is not a practical consideration, it should also be understood
that any such connection to the Town of Mooresville would result in an inter basin transfer
of water from the Catawba River Basin to the Rocky River Basin. This is obviously a
sensitive matter and such transfers are typically discouraged.
We are returning and resubmitting herewith, the EAA with this letter addressing the concerns in
your letter. As noted and explained herein, the EAA does properly support the projected flow data
and provides adequate documentation of the current property owner's development intentions, in
keeping with guidance for preparing EAA's.
We will appreciate your proceeding with the processing of our application for renewal of the current
permit as it is now written and as has been substantiated through the EAA for an existing flow rate
of 0.100 MGD and expansion to 0.300 MGD upon submission of plans and specifications, receipt
of Authorization to Construct and completion of construction of facilities adequate to expand the
existing capacity to the full approved 0.300 MGD.
We appreciate your assistance in these matters.
If you have any questions or if there is anything we need to discuss, please let me know.

This letter is a follow up to our conversation regarding the sewer system needs for Big Daddy's.
As you are aware, we have seating capacity for a maximum of 500 people. We have no plans for
expansion at this time. I have discussed this matter with Ms. Gail Derwort with the Iredell
County Health Department and to the best of my knowledge, there is no limit on our seating
capacity imposed by the health department.
In the early nineties, Big Daddy's used septic tank disposal as the means for wastewater
treatment but due to growth of the restaurant, catering and the construction of additional
buildings in the remaining open areas, we participated in the cost of constructing the Highway
150 wastewater treatment plant years ago in exchange for being allowed to connect onto that
system.
We would like and need to retain the c+city for our restaurant in the Highway 150 wastewater
treatment plant. `

Subject: RE: Hwy 150 WWTP EAA Meeting dates
Dear Mr. Horne,
As we discussed, Michael Parker's original purpose of having the meeting was
to go over all the additional work you have done to address DWQ's concerns in
the letter dated Sept. Yd and to simply resolve the few outstanding questions you
might still have in some areas. With that purpose in mind, I told him I could
come down to the Mooresville Regional Office.
Today you informed me that you (and Aqua) disagree with the need for most of
the information requested in the letter and the purpose of the meeting was to
come and discuss each question and the necessity of the information requested. 1
would be glad to meet with you and clarify the items requested and perhaps we
can agree on consolidating what is needed from the Department of Health, Town
of Mooresville, and an easy way to verify users (ie. customer billing list). The
questions in the letter are based on DWQ's Engineering Alternative Analysis
Guildelines and all new and expanding facilities are required to submit this
information. It is disconcerting that I am just hearing such concerns exist seven
weeks after the letter was sent. However, note that questions relating to DWQ
policy would be best answered by having all the appropriate staff from DWQ
present at the meeting. Therefore, I am requesting that the meeting be held in
Raleigh so Aqua's concerns can adequately be addressed. At the last meeting,
held with Aqua representatives in the Mooresville Regional Office, I thought
Michael said his office was located in Cary so perhaps this will work for him as
well.
I would hope we could schedule the meeting in Raleigh within the same
timeframe you requested - sometime before or on Nov. 12th. In fact, November
12th at 11 am would work for us here.
Again, please be aware that this facility is on EPA's Priority Permit list. At
some point DWQ will have to proceed with processing this permit application.
If an adequate EAA is not received, we will consider issuing this permit with no
expansion.
Sincerely,
Julie Grzyb

Please be aware that this facility is on EPA's watch list. At some point DWQ will have to proceed with finalizing this
permit application, with or without an adquate EAA.
The EAA Guidance Document requests all the information asked for in the letter sent Sempter 3, 2010. For your
clarification, the letter was an attempt to specifically relate the information requested in the Guidance Document
(mainly Step 2 and Step 3) to the projections and feasible alternatives specific to the Hwy. 150 WWTP.

Dear Mr. Schlobohm:
Dee Freeman
Secretary
This Office has completed a review of the Engineering Alternatives Analysis (EAA) submitted by Aqua
North Carolina and offers the following comments.
In an earlier discussion with Mr. Michael Melton of Aqua NC, it was noted that the most important and
difficult part in the preparation of an EAA is obtaining the supporting documentation to justify the projected
flow numbers. As explained to Mr. Melton, the Engineering Alternatives Analysis submitted by Hydraulics,
LTD in Dec. 2003 was never approved by the Division since justification for the projected flows were never
provided. The EAA submitted by J. Thurman Horne on behalf of Aqua NC, Inc. also includes proposed flows
that lack sufficient justification, therefore, the subject EAA submitted by Aqua North Carolina is being
returned. The following information and questions need to be addressed.
Existing and Potential Flows
1. All existing flows should be clearly documented and potential flows to the WWTP must be
substantiated by the owners of the properties located within Hwy. 150 WWTP's service area. A review
of Discharge Monitoring Reports (DMRs) submitted from 2006 through 2009, currently document an
average flow of 0.022 MGD and a maximum flow of 0.055 MGD to the Highway 150 WWTP. River
Park, Pier 16 and Hydraulics, LTD have never substantiated the need for the WWTP to plan for the
flows at which the collection systems were designed. Based on our review of the DMRs, actual flows
from Pier 16 and River Park are likely well below the projected numbers set forth in the EAA. For
example, the EAA uses a projected flow of 18,500 gpd for the Pier 16 pump station, however, actual
flows are likely much lower and there is no justification provided for any future growth (and associated

flow) in this area that would support the requested 18,500 gpd flow. The potential flows (ie. 45,590 gpd
from River Park and those not supported by actual development plans at Pier 16) should be substantiated
by the owners of the property with actual building plans and written requests for increased discharges
beyond currently discharged flows. A description of proposed commercial plans (plat drawings of
future buildings), building uses, and the timeframe by which these buildings will be phased in should be
provided by the owners and included with the EAA. Owners must also document that other methods of
wastewater disposal are not feasible (ie. septic systems or connection to county sewer system) and
include a specific request to discharge to Aqua NC's Hwy 150 WWTP for the existing and projected
volumes of wastewater.
2. A letter from Big Daddy's should be provided that includes the actual Health Department permitted
capacity of the restaurant and that other methods of wastewater disposal were not feasible (ie. on -site
disposal or connection to county sewer system).
3. Does Aqua NC have actual flow date for the dischargers listed in Table 1.01 as being currently
connected to the Hwy 150 WWTP? If so, this information should be included in the EAA.
4. It is understood that 238 individual residential lots in the Ridgetop Road Development were once
considered a significant portion of the original EAA. Many of these homes were built using onsite
wastewater disposal systems. Based on current soils information, the soils appear suitable for septic
systems within that development. Please provide documentation as to why the remaining 11 lots cannot
install septic systems for wastewater treatment as well. The development owner (or owners) should
verify with a letter from the local Health Department that this is not an alternative for the additional lots
before this flow can be added to the flow calculations.
Future Flows
5. The owner of the Lake Norman Promenade should provide plans (basic plat drawings) of the proposed
development, building uses, and a timeframe on how the project is scheduled to be developed. All
flows will have to be substantiated by the owner and his desire to connect to the Highway 150 WWTP
should be in writing.
6. Projected domestic and commercial growth numbers can not be considered in the flow calculations.
Both the 2003 EAA and the current EAA projects a 55% increase in population and commercial growth
in the next 20 years. However, as a result of the economic downturn that began in 2008, actual growth
(both in population and commercial) has dropped significantly and is not likely to change in the
foreseeable future. Please note that a privately owned facility must justify population and commercial
growth projections using actual (approved) land use numbers, which includes specific plans on how the
land located within the WWTP's service area is to be developed.

7. Using information on actual existing discharged flows, supporting documentation on possible
expansions from current dischargers, and supporting documentation from future land use and flows,
provide a schedule for the proposed build out of the WWTP.
Alternatives
After reviewing this EAA, it is unclear as to whether a discharge to the Hwy. 150 WWTP is the most
environmentally sound disposal alternative. In order to fully assess the alternatives, the flows being
requested in the EAA must be justified and substantiated. Furthermore, it may be possible to connect to
the Town of Mooresville (the Town) provided sufficient capacity exists at the Town's POTW. The
EAA should include documentation from the Town as to whether sufficient capacity exists at the
Town's WWTP to accept all flows currently tributary to the Highway 150 WWTP and their willingness
(or lack thereof) to accept this flow.
In summary, the flow projection table found in the subject EAA must be supported with actual and
projected flow data, and documentation from the current property owners as to their development intentions and
their desire to connect to the Highway 150 WWTP. Once this documentation is received, the alternatives can
be re-evaluated according to the justified flow. Please call meat 919-807-6389 or email meat
[e-mail] if you would like to discuss any of these items in more detail. To continue processing
of this permit application, the Division requests a response to these comments within 45 days.

Dear Ms. Grzyb:
Attached are three (3) copies of the subject updated Engineering Alternatives Analysis (EAA)
and an updated application for permit renewal. The new, updated EAA uses much of the work
and references the 2003 EAA extensively. Therefore, I have also attached three (3) copies of the
2003 EAA to assist in your review.
As you requested, this review included an update of flow projections. These projections show
that, for the twenty (20) year planning period, wastewater flow is expected to reach levels
requiring expansion of the existing WWTP to the.full 300,000 gpd capacity as allowed in the
existing permit. Therefore our application for renewal remains a request to renew the permit to
continue to allow for this future expansion.
As you will see, the conclusion of the updated EAA is that, continued treatment and discharge to
surface waters is the most practical alternative.
We appreciate the assistance and interaction with you and the staff of the Division of Water
Quality in our efforts to proceed with the permit renewal process. If you should have any
questions or need any additional information, please call me. You should also feel free to contact
the engineer (Horizon Engineering & Consulting, Inc.) to discuss any technical matters
pertaining to, the updated EAA.

Dear Mr. Melton,
Dee Freeman
Secretary
Subject: Application for NPDES Permit No. NCO074900
Highway 150 WWTP
Iredell County
As you requested.. I am following up with a letter regarding our meeting on the Highway 150
WWTP permit held last week at the Mooresville Regional Office. As you can see, this permit has a
complicated history and the Division is committed to adhereing to the Environmental Management
Commision's ruling on this case.
If you would like to review or obtain a copy of the Dilution Study for Hydraulics, LTD and the
Engineering Alternative Analysis(EAA) submitted to the Division of Water Quality in December
2003, please contact Michael Parker at the Mooresville Regional Office at 704-663-1699. He
informed me that they have a copy of both submittals. The Dilution Study does show adequate
dilution at 212 gpm and no further information is required on this subject at this time. If Aqua NC
requests a significant change to the discharge rate than a new dilution study may be required. To
proceed with a proper review of this discharge and permit, a new or amended EAA is required
along with a NPDES permit application.
Aqua NC can acquire a copy of the NC Form D application for privately owned, 100%
domestic facilities with a design flow of less than 1.0 MGD, from the Division of Water Quality's
web -site at: http://Portal.ncdenr.org/web/wq/swp/ps/npdes/appforms. An application and
instructions for completing an Engineering Alternative Analysis can also be obtained under the
web -site and is listed toward the top of the page. Adequate flow justifications) and an assessment

of possible alternative disposal methods are necessary before a permit can be issued. Please be
aware that many questions were raised by local ciitizens on the flow justification(s) contained in
the December 2003 EAA submittal.
It is my understanding that we both would like to see this process through as quickly as
possible. If you could give us an estimate of how long you think Aqua NC will need to complete the
EAA and application requirements perhaps we can agree on an appropriate timeframe.
If you have questions, please contact me by e-mail ([e-mail]) or call me at
[phone].

DWQ - Michaell Parker, Engineer, Mooresville Regional Office
Julie Grzyb, Engineer, Archdale- Raleigh Office, NPDES
Tom Belnick, NPDES Supervisor, Archdale — Raleigh Office
I. Discuss Environmental Management Commission, NPDES Committee's recommended
decision in 2003:
A. Rescind the 2000 NPDES Permit upon following conditions:
1. The rescission is stayed and the facility may continue to operate and discharge
under 2000 permit for one year or, longer if necessary, until the decision is
made on the application, (pursuant G.S. 143-215.1), to issue or deny a new
NPDES permit;
2. The 0.10 treatment capacity and effluent limits specified in the 2000 permit
are applicable while the facility operates as provided under this final decision;
3. The applicant, in conjunction with an application for a new permit, shall
submit an analysis of the "practicable waste treatment and disposal
alternatives" to the surface water discharge; and
4. The appliccannt for the new permit shall perform and coordinate with the
Dept.'s DWQ any water quality modeling and impact analyses deemed by the
Division Dinas necessary for a complete application for a new permit.
December 2, 2003- Hydraulics, LTD submittted an NPDES application, an Engineering
Alternative Analysis and a Dilution Study for the Highway 150 WWTP.
Discussions continued between DWQ, Town of Mooresville, and Hydraulics in hopes of
connecting Hwy. 150 to the Town ofMooresvillle WWTP. Concerned citizens requested that
Hwy's 150's permit not be reissued. P� r,r 14 c..h ne r-tr -Yv (F-61 1-f° -at -7 ° C S '
To date: Highway 150 has maintained compliance with its NPDES permit requirements.
Local citizen compliants have ceased during the last couple of years.
To process this permit:
1) Submt a revised application — Short Form D
2) Determine flow to be requested on Permit.
3) Submit a revised EAA which justifies the flow being requested. Include letters of
confirmation from facilities or subdivisions which intend to discharge to Hwy 150 in the future.
4) The EAA should include a cost analysis which assesses the costs of the current Hwy. 150
facility, collection system, etc. since this is considered a new application, by law. As a new
application, alternative disposal methods for all flows, existing and future, should be considered.q J c� l
Future flows estimated in the Hwy 150 WWTP flow request should be analyzed separately for
disposal alternatives or a combination of alternatives.CIA
5) A letter is needed from the nearest WWTP acknowledging whether the facility is capable of S -3-
receiving Highway 150's wastewaters. If it can, this possibility should be included in the
alternative cost analysis.

Hydraulics - Hwy 150 WWTP
Michael Melton,
Just wanted to let you know I am the permit writer who will be working on addressing the Hwy 150 WWTP
application. I am reviewing the file — which is several feet high — and hope to draft a letter next week identifying what
information or updated material may be needed to process this application. To make sure we adhere to whatever
requirements were intended as part of the legal settlement I will need to discuss this case with several staff members
who know the case history.
If I have any questions on some of the information (application, EAA, Dilution study) submitted, would you be the first
person to contact? And may I have a contact phone number as well?
Thanks,
Julie Grzyb

History of HWY 150
EAA
2000 Permit — Cresent Resources agreed to give up a 400,000 gpd discharge permit to lake Norman in exchange for
Hydraulics agreeing to serve developments that might occur on their remaining land holdings in the area (look for
letter of agreement)
Hydraulics agreed to purchase Pier 16 and pump flow back to Hwy 150 thus eliminating discharge.
Pier 16 was owned by Heater Utilities.
Total justified flow is 302,325 gpd of which 100,000 gpd is from single family homes primarily on Cresent Property.
Dept. of Justice
June 6, 2003 -1996 and 2000 permits (issued 10-11-2000) were rescinded by Judge Conner
-EMC, rescission is stayed and facility may continue to operate and discharge under 2000 permit for 1 year or, longer
if necessary, until the decision is made on the new aplllaction (to issue or deny).
-In conjunction with an application for a new permit, applicant shall submit an analysis of the "practicable waste
treatment and disposal alternatives".
-coordinate with DWQ on any water quality modeling and impact analyses
Sept. 29, 2003 — Town of Mooresville gives okay for Hwy. 150 to connect to WWTP and costs are spelled out. Letter
acknowlodges that Hwy 150 may need to discharge as much as 1 MGD at some future time.
Sept. 17, 2003 — Letter from Willis Engineers to Town says up to 300K could be handled
by McCrary Creek pumping station.
Dec. 2, 2003 — Hydraulics submits new application (short form C), EAA and Dilution Study for Hwy 150
May 2004 — Hwy 150 informed of new zoning ordinance on expansions from Mooresville.
Apr 16, 2004 — email from Rebecca Harger, Iredell County Planner to Michael Myers recognizing Mariano Nursing
Home contrary to Iredell's River Corridor Plan.
May 17, 2004 — email from Jack! Power to Coleen stating substantial inaccuracies in Hydraulics Flow Analysis. Cresent
Resources, Mariano Nursing Home, Hotel and Conference Center, Jay's Food Store should be removed and Auto
Collision Shop should be added.
May 17, 2004 — email from Jay Bunzey to Bill Ross requesting that Hwy 150's permit not be reissued.
July 13, 2004 — letter from Rex Gleason of DWQ acknowledging ordor complaints, requesting action when appropriate
and asking who the operational contacts at the facility are. Also, recognized a change of ownership was forthcoming?
2006 — 2007 memo's between DWQ and Town of Mooresville (Allison Kraft, Engineer) that Town perference is to take over
these service areas. This is not likely to occur, at least not for 10 years after WWTP is expanded?
Jan. 15, 2009 — spoke with Delbert Likins, Hwy 150 Wastewater Supervisor, works for Aqua NC. Aqua did buy Pier 16
and wastewaters are pumped to Hwy 150 for treatment. Not much has become of Cresent Resource's development
just a Business Park. Only looking for a 0.100 MGD permit not a phased permit, they have no plans to expand.
Current flows are around 30,000 gpd. He asked if the fecal monitoring could be reducted to 1/week as required by
most Grade II facilities, they are sampling 7 days/week. Told him we would look into it as the permit is developed.
They have added turbidity monitoring. Informed me Mike Melton is Compliance Manager and responsible for filing
for permits, he can be reached at 704-489-9404 ext. 57238.

Mike, some time ago, you and I talked about the Renewal for the Hwy 150 Permit. Also, Aqua had asked Rex Gleason to
look into the situation. The last we were told was that the renewal had had slipped through the cracks and permitting had
not renewed. We are of course very concerned about it. I would like to set up a time with you either Monday afternoon
(January 4'h) or Tuesday, 1/05 to discuss the situation. Can you let me know if either time works with you? Thanks

PREFACE
FM
This report is an updated Engineering Alternatives Analysis (EAA) which is intended to
address the current state of conditions and projections for the next twenty years at the
�+ Highway 150 WWTP. This report uses the original Engineering Alternatives Analysis,
prepared by Wright & Associates submitted December 2, 2003 (hereafter referred to as
the 2003 EAA) for Hydraulics, LTD.(which has since been acquired by Aqua North
Carolina, Inc.) as a basis to assess the current status and the projection for conditions
during the next twenty years as compared to the descriptions, findings and
recommendations of the 2003 EAA.
In preparing this report, the engineer, in conjunction with the staff of Aqua North
Carolina, Inc., investigated the existing facilities and conditions at the Highway 150
WWTP, and has assembled this report which provides an update to reflect changes in
conditions since preparation of the 2003 EAA. This includes noting and describing
where conditions have changed since the original plan, making revisions to flow
FM projections, alternative assessments, cost estimates, etc. where necessary to provide
an up to date analysis.
' The format of this update uses the format of the 2003 EAA as a base reference, and
provides a statement of the findings, update, etc. corresponding alphanumerically with
each section of the 2003 EAA. The reader is encouraged to review the original 2003
EAA at the same time while reading this update, since it serves as a companion
to understanding the content herein.

The information contained in thOW e 2003 EAA is still accurate with the exception of the
following:
1. Aqua North Carolina, Inc. is the legal name of the owner and operator of the
Highway 150 WWTP.
2. An application for renewal of the NPDES permit and a revised EAA (the 2003
EAA) was submitted to the state and is stamped as received on December 2, 2003.

Project Description and Approach
The information contained in the 2003 EAA is still accurate with the exception of the
following:
1. Horizon Engineering & Consulting, Inc. has been retained to review the 2003
EAA and to provide this update. This update reflects current (2010) conditions
and projections for the twenty year planning period following the most recent
FM

1. Residential growth in the study area has increased the number of existing single
family homes and decreased the number of unoccupied lots. The 2003 EAA
identifies approximately 185 acres of land that was considered to be potential for
building 238 additional homes. This area, which is shown as item 13 in "Table 1.0,
Flow Justification" in the 2003 EAA, has been largely developed with single
family homes. Therefore, the updated flow projection no longer uses this as an
anticipated significant block of future residences for connection to the Highway
150 WWTP.
The remainder of the description of the study area is accurate with the exception
that the amounts and types of wastewater contributors presently connected to the
Hwy 150 WWTP and the projected types and amount of future growth are revised
and described in detail in Section 4 — Flow justification of this updated report.

The information contained in the 2003 EAA is still accurate with the exception of the
M following:
1. There are now a total of seven (7) pump stations which are a part of the Highway
150 WWTP sewer collection system. Several of these pump stations serve
individual establishments. A pump station has been installed that collects
wastewater that was previously sent to the Pier 16 WWTP for treatment and
discharge. The Pier 16 WWTP has been eliminated as a consequence of the
construction of this new pump station. Gravity sewers have also been installed in
the River Park commercial park.
A plan drawing showing the pump stations and force mains tributary to the
Highway 150 WWTP is included in this report as Figure 1 A.

Guiding Principles and Tools
Ae information contained in the 2003 EAA has been updated as a consequence of the
investigations made in the course of developing this update. This updated flow
justification is an inventory of existing sources of wastewater already contributing to the
Highway 150 WWTP, plus a projection of future increase in this flow which is
attributable to currently planned development projects that can be specifically identified
and future increase in flow that can be projected based on past, current and future
projected growth and development trends.
In addition to the "River Highway Corridor, Future Land Use" document developed by
Iredell County and used in the original 2003 EAA, this update has utilized the "Iredell
County 2030 Horizon Plan" adopted by the Iredell County Board of Commissioners on
►+ September 15, 2009. This study provides an excellent source of information for
projecting future growth and development in Iredell County throughout the twenty (20)
year planning period.
Excerpts from this report are included as Appendix N.
The 2003 EAA describes plans to eliminate the existing Pier 16 WWTP and to connect
this flow to the Highway 150 WWTP. This has been completed now and the permitted
capacity of the former Pier 16 WWTP is now shown as an existing contributor to the
Highway 150 WWTP.
ON As previously noted, the 2003 EAA identifies approximately 185 acres of land that was
considered to be potential for building 238 additional homes. This area, which is shown
am as item 13 in "Table 1.0, Flow Justification" in the 2003 EAA, has been largely developed
with single family homes. Therefore, the updated flow projection no longer uses this as

8
an anticipated significant block of future residences for connection to the Highway 150
WWTP.
A new Table (Table 1.01) has been prepared and included in this report to identify those
am existing sources, planned additional sources that can be specifically identified and
projected future area growth that all combine to establish the projected total wastewater
FM flow anticipated for the (20) twenty year planning period.
At present, there are two (2) planned additional development sources that can be
No specifically identified. These are included in Table 1.01 as item 13 (Ridgetop Road
Development) and item 14 (Lake Norman Promenade.)
m, The Ridgetop Road Development is an eleven (11) lot, single family residential
development that is nearing completion. The developer of this project is Mariano
Construction Company. In conversation with the owner (Mr. Anthony Mariano, Jr.) on
May 21, 2010, Mr. Mariano explained that the original plans for this property as
described in the 2003 EAA, were abandoned. In the 2003 EAA, this parcel was identified
as item 10 (refer to Table 1.0 of 2003 EAA) and was to be a 160 bed retirement home.
Instead, the property has been divided into eleven (11) large individual residential lots.
FM Wastewater treatment for this development will be provided by the Highway 150
WWTP.
`M Lake Norman Promenade is a multiuse development that is under planning for
development by the owners, Lake Norman Promenade, LLC. This property is a 16.6 acre
tract that has been used in the past for various commercial uses. At the time of the 2003
EAA, the then owners of the property had plans to develop a conference center and hotel.
The property was sold to the new owners before these plans were implemented.
The new owner's have engaged an architect (Robert Johnson Architects, Inc.) who has
® made preliminary plans for developing the property including a resort hotel, conference
center, condominiums, retail shops and boat slips. The specific size of each of these
go elements and the anticipated flow that would be conveyed to the Highway 150 WWTP is
detailed in the Table 1.01 of this report and the detailed flow calculations.
P, Flow Justification Results

MR projections for wastewater capacity requirements for the (20) twenty year planning
period.

The "2030 Horizon Plan" notes that a 22 % increase in population is expected from 2007 to - -
2015. This projects to a rate of population increase of 2.75% per year (22%/8yr.)
Using this projected rate of population increase (2.75%!year) for the twenty (20) year
planning period, we project an increase in population and residential growth of 55%
(20 years x 2.75%) Therefore, it is projected that the current domestic wastewater contribution
should increase by 55 %. Similarly, it would be expected that nonresidential growth
would proceed at a rate corresponding to the population growth. Hence, it is projected that
the current nonresidential wastewater contribution should increase by 55%.
55°% x 95,640 = 52,600 gpd Projected domestic growth =

no
300,000 gpd and since Aqua North Carolina, Inc. has no desire to request an increase in
this amount at this time, the evaluation of alternatives remains at 300,00 gpd, just as it
was at the time the 2003 EAA was prepared. Just as was done in the 2003 EAA, the
evaluation of alternatives in the update assumes approximately 1 /3, or 100,000 gpd, of
the total will come from single family residential growth.
Section 5 — Alternative Descriptions (Update)
am

General
no
The investigation of conditions in preparing this updated report have resulted in some
revisions in the types and amounts of wastewater projected from existing sources and
'4 future growth. Although the total projected volume of wastewater that Aqua North
Carolina, Inc. expects to accommodate at the Highway 150 WWTP remain a same
Am (300,000 gpd), the change in the sources of these projections has a rofound affec on the
evaluation of alternatives that was done in 2003. The 2003 EAA projected 100,000 gpd
of domestic wastewater from a possible 238 single family residences as being projected
contributing flow to the highway 150 WWTP. These were those areas that were
undeveloped at that time (referred to as "Crescent lands.") These areas have since been
partly developed and the developed lots did in fact use individual septic tanks. These
areas were referred to in the 2003 EAA as being approximately 238 lots and are shown in
Figure 9.
The conditions under which Alternatives 1, 2, 3, 4, 5 and 10 were evaluated under the
2003 EAA have changed in that the 100,000 gpd of domestic wastewater from the
possible 238 individual residential lots identified are not included in the flow projections
of this updated report as areas being anticipated for connection to the Highway 150
WWTP.
Since the updated flow projection of this report does not anticipate the single family
residential development in these areas as a contributor to the updated flow projections, it
is no longer appropriate to consider the use of individual septic tanks for these residences
as having any consequence to the evaluation of alternatives for the Highway 150 WWTP.
Since Alternatives 1, 2, 3, 4, 5 and 10 were based on the projection of 100,000 gpd from
these possible 238 individual lots and since the evaluation of these alternatives included
using individual onsite septic disposal systems as part of the method of treatment for the
projected flow, these alternatives are no longer considered applicable.
OM

10
Hence, Alternatives 1, 2, 3, 4, 5 and 10 of the 2003 EAA are eliminated from further
evaluation and deleted in this updated report.
However, the remaining Alternatives 6, 7, 8 and 9 are considered to be consistent with
fm the updated flow projection and applicable alternatives which should be considered.
These alternatives will be further described and updated to reflect existing and projected
am
am
conditions in the remainder of this report.
With the exception of the previously described change in the projection of domestic flow,
the assumptions used in the 2003 EAA (Table 2.0) are still valid and the analysis of the
remaining (4) different alternatives for wastewater disposal is still a very comprehensive
evaluation of possible alternatives. Again, it should be noted that the former WWTP at
Pier 16, referred to in Table 2.0 has in fact now been eliminated and the flow diverted to
the Highway 150 WWTP.
Soils Analysis for Land Based Alternatives
Soil conditions in the area have not changed and the information contained in the 2003
EAA is accurate.

Alternative 5
As explained in the General portion of this section, this Alternative is no longer
applicable and has been eliminated from further consideration in this updated report.
Alternative 6
This alternative is to eliminate the existing surface water discharge by using the existing
Highway 150 WWTP as a pretreatment system for the entire 300,000 gpd, followed by
surface land disposal of the pretreated effluent by using drip irrigation.
Most of the information contained in the 2003 EAA is still accurate with respect to the
evaluation of this alternative. However, as discussed in the General portion of this section
of this updated report, the proposed 238 lots described in the 2003 EAA are no longer a
part of this evaluation. Also, the former Pier 16 WWTP has been eliminated and a pump
station has been installed which conveys the wastewater to the i ay 1
Other than deleting these items from estimated cost calculations, this has no effect to the
design evaluation that was conducted and therefore, all other conditions and conclusions
remain as determined in 2003.
FM All design elements, proposed locations and considerations for Alternative 6 remain the
same as concluded in the 2003 EAA. The only change to be noted is that the projected
,', costs associated with this alternative have been updated in this report to delete previously
projected costs for the 238 residential development and for eliminating the Pier 16
WWTP, and to adjust for inflation. The update in cost projections is described in

Alternative 7
This alternative is to continue discharge into surface water by using the existing Highway
150 WWTP with expansion for the entire 300,000 gpd. The existing WWTP has facilities
to adequately treat up to 100,000 gpd. This alternative considers the implications of
expanding the existing WWTP as necessary to treat 300,000 gpd.
Most of the information contained in the 2003 EAA is still accurate with respect to the
evaluation of this alternative. However, as discussed in the General portion of this section
of this updated report, the proposed 238 lots described in the 2003 EAA are no longer a
part of this evaluation. Also, the former Pier 16 WWTP has been eliminated and a pump

station has been installed which conveys the wastewater to the Highway 16 WWTP.
Other than deleting these items from estimated cost calculations, this has no effect to the
design evaluation that was conducted and therefore, all other conditions and conclusions
remain as determined in 2003.
All design elements, proposed locations and considerations for Alternative 7 remain the
same as concluded in the 2003 EAA. The only change to be noted is that the projected
costs associated with this alternative have been updated in this report to delete previously
projected costs for the 238 residential development and for eliminating the Pier 16

The information contained in the 2003 EAA is accurate and is still applicable although
'M former Alternatives 1,2,3,4,5 and 10 have been eliminated as discussed earlier in this
report.
Whereas the location and size (300,000 gpd) of the existing and evaluated potential
facility modifications and additions have remained essentially the same, the consideration
of various economic and non -economic factors associated with the alternatives and the
conclusions there from remains applicable.
The conclusion of the expert panel was that the discharge of up to 300,000 gpd of treated
wastewater from the highway 150 WWTP , best achieves community objectives. There
has been nothing derived from this updated review and evaluation to alter those
conclusions.

The two (2) requests for service included in the 2003 EAA are no longer valid. Each of
am the two (2) owners have undergone changes which have substantially altered the plans
that were the basis for their request.
FM The properties that were the basis for the requests included in the 2003 EAA still exist
and are in stages of developing into being significant contributors to the Highway 150
WWTP. These are included in Table 1.01 as item 13 (Ridgetop Road Development) and
item 14 (Lake Norman Promenade.) The revised plans and status of these properties and
the plans thereto are described below.
The Ridgetop Road Development is an eleven (11) lot, single family residential
development that is nearing completion. The developer of this project is Mariano
Construction Company. In conversation with the owner (Mr. Anthony Mariano, Jr.) on
t
May 21, 2010, Mr. Mariano explained that the original plans for this property as
described in the 2003 EAA, were abandoned. In the 2003 EAA, this parcel was identified
s as item 10 (refer to Table 1.0 of 2003 EAA) and in a letter in Appendix B and was to be a
160 bed retirement home. Instead, the property has been divided into eleven (11) large
individual residential lots. Wastewater treatment for this development will be provided
by the Highway 150 WWTP.
The property formerly owned by Mr. Jack Williams, Queens Landing, has been sold to
Lake Norman Promenade, LLC. The property is still being planned as a multiuse
development that is under planning for development by the owners Lake Norman
Promenade, LLC. This property is a 16.6 acre tract that has been used in the past for
various commercial uses. At the time of the 2003 EAA, the then owners of the property
had plans to develop a conference center and hotel. The property was sold to the new
owners before these plans were implemented.
The new owner's have engaged an architect (Robert Johnson Architects, Inc.) who has
made preliminary plans for developing the property including a resort hotel, conference
center, condominiums, retail shops and boat slips. The specific size of each of these
elements and the anticipated flow that would be conveyed to the Highway 150 WWTP is
detailed in the Table 1.01 of this report and the detailed flow calculations.

Z030 HORIZON PLAN
Historic Population and Household Growth
The most recent population and household figures for Iredell County are available in the Iredell County
Demographic Forecast (2008). This report estimates that the full-time population of Iredell County was
122,660 in 2000 and increased by 22% to 149,877 in 2007. Looking back further, the county
experienced slow, steady growth from 1970 to 1990. Population growth has been increasing more
rapidly since then.

Nearly 30% of the growth in Iredell County between 2000 and 2007 was in the rapidly developing Mount
Mourne area south of Mooresville and in the lakeside communities located west of Interstate-77 and
south of NC-150. (See the Population Change Map in Appendix B.)
In 2000, Iredell County had 47,360 households. This increased to 58,487 in 2007 - adding an additional
11,127 households, an increase of 23.5%. Almost one-third of the new households are located in
southern Iredell County along the shores of Lake Norman south of NC-150 and in the Mount Mourne
community. Households grew most rapidly in the areas surrounding, but not including, Mooresville.
Beginning In the 1990s, the county's annual growth rate increased from 1.19% to 2.81%, and increased
_ again to 2.9% by 2007. Actual population in 2000 surpassed the projected population outlined in the
county's 1997-2007 Land Use Plan by over 8,000. Actual population in 2007 exceeded population
projections for 2010 by over 21,000. The county's population growth has far exceeded the amount of
growth that was projected last decade. One reason for this rapid growth is the strong job market in
both Charlotte and Iredell County. National companies such as Lowe's, Bank of America, First Union,
and Wachovia have expanded their presence in the region.
-• Community Diversity and Age
Comparisons of U.S. Census data for race and ethnicity between 2000 and 2006 show that there has
been a small decrease in the percent of white and black/African American populations in the county.
The percentage of other races has increased from 4.2% to 6.1% over the six year period. During this

aligns with the increase in Hispanic populations experienced nationally. (See the Race and Ethnicity Map

The median age of Iredell County's population was 36.6 in 2006, a slight increase from 2000. Unlike the
national trend, it appears that the percentage of the county's population 65 years and older is not
increasing; however the percentage of people in the 55 to 64 age group did increase during this period.
The percentage of the county's population under the age of 5 decreased slightly during this period.

Population Projections
The Iredell County Demographic Forecast reports that the county population will add another 39,941
people by the year 2015 -- a 22% increase from 149,877 to 189,818.
These new people will result in approximately 6,447 new households in the county. Southern Iredell is
expected to be the fastest growing area in the county, followed by the central areas near Statesville and
Troutman. Over 52% of those households are expected to live in the Lake Norman and South Iredell
High School attendance zones in south Iredell County.

The Iredell County Inspections Department issued 380 building permits for over 3.8 million square feet
of nonresidential development between 2000 and 2007. The number and amount of permits issues
annually increased during this period, except for 2006.

Build -Out Scenario
In addition to preparing population projections, another way to look at future growth is to determine
the potential for future development, often called "build-
out potential." The build -out potential refers to a future
scenario where all lands in the county that could be
developed are developed, resulting in the maximum "build-
out' capacity In the county. .b..« M i
owro toaty
Analysis of Iredell County's build -out potential reveals that
there is capacity to develop more than 101,000 acres of
land resulting in more than 79,000 residential units in the
county that could provide homes to approximately 190,000
_ additional people. Hypothetical population growth under
build -out is approximately equivalent to 1.27 times the
2007 estimated population, more than doubling the 2007
population. This analysis was broken down by four planning
areas to reveal the general locations where development
potential exists. The table below shows the general
breakdown of developable acres, new residential units, and
new population by planning area. See the Planning Districts
Map in Appendix B and to the right for the geographic
boundaries of the four planning areas.

To conduct more detailed planning for sections of the
county, four planning districts were identified.

With current growth expectations, transportation infrastructure, and limitations of water and
wastewater capacity in Iredell, a build -out scenario is not expected to occur anytime during the life of
this plan, or possibly ever. Moreover, many landowners, particularly those in the farming industries,
may not be interested in developing their lands in the future. While a build -out scenario is highly
unlikely, it is helpful for gaining an understanding of the potential for future residential development In
the county under current policies and regulations, and illustrates the extent to which that development
could occur. These calculations reveal significant development potential in the county, albeit unlikely to
occur by 2030, if ever.
Development Regulations
Iredell County is responsible for managing and permitting development within the unincorporated areas
of the county that lie outside of municipal planning and zoning jurisdictions. The county uses several
ordinances to regulate land development in the county as listed below.
• Zoning Ordinance
_ • Watershed Ordinance
• Subdivision Ordinance
• Erosion Ordinance
■ Floodplain Ordinance
• Building Code
• Minimum Housing Code
The Iredell County Department of Planning and Development is responsible for enforcement of each of
these ordinances, except for the Building Code and Minimum Housing Codes which are enforced by the
Iredell County Department Inspections Department.
Land Use Planning
Historically, the county and towns in Iredell have undertaken independent planning efforts. In recent
years, the approach has changed and there is now a strong cooperation regarding land use planning.
_ The county has focused land use planning efforts over the last decade on certain high growth areas in
the southern portion of the county and near Statesville and has coordinated with the towns on these
efforts. Many plans were reviewed to develop the 2030 Horizon Plan, including the municipal land use
plans for the three southern towns and several small area plans. These land use plans include:

■ River Highway (NC -150) Corridor Future Land Use Study (Iredell County, 2000)
• U.S. 70 East Corridor Study (Iredell County, 2002)
Regional Land Use Planning
Land use plans for the counties and towns adjacent to Iredell County will have an effect on future
-. growth and development along the borders of the county. The Regional Context Map, located in
Appendix B, illustrates the land use plans for these jurisdictions and identifies several key areas for the
future. These include:
The development "push" coming from the greater
Charlotte region will continue to provide demand for new
construction in southern Iredell County. Over time, it is
expected that Mooresville will continue to grow, and that
development pressure will move north to Troutman and
^
Statesville.
■ The North Carolina Research Campus in Kannapolis will
likely spur new development and traffic impacts along
roadways along the eastern and southern boundaries of the
county.
Traffic congestion is one of the key impacts
addressed in the 2030 Horizon Plan.
• The Town of Catawba in Catawba County will possibly
^ annex lands in Iredell County at the border. A new development may be slated for this area that
will require public infrastructure that could potentially be provided by the town. Development
in Catawba County along NC-150 will likely have an impact on River Highway (NC-150) in Iredell
County.
The Town of Davidson expects that the lands along the border of Iredell County will remain
rural in character over the long-term and will not have an impact across the border in Iredell
County. One idea is to create annexation agreements between Davidson and Mooresville to
ensure coordinated planning in areas of joint interest.
• The areas along the boundaries of Wilkes and Yadkin Counties and Iredell County are likely to
remain as low -density rural lands. Both counties are designating farmland preservation districts
in these areas.

IREDELL COUNTY
2030 HORIZON PI,AN
FUTURE LAND USE
Through the Future Land Use, Iredell County is detailing how best to accommodate future housing and
commercial and employment development. The Future Land Use map was developed over the course
of several months and included input from the community, representatives of the municipalities, and
the committees overseeing development of the plan. It uses the Growth Areas Map as a guide for
locating future development into cohesive growth areas that will likely one day be within the corporate
limits of one of Iredell County's towns and blends previous planning efforts into one guiding document.
Future Land Use Classifications
The following section describes the land use classifications shown on the Future Land Use. These land
use classifications are intended to guide future development decisions, provide direction for re -zonings,
and provide a foundation for the future update to the county's Zoning Ordinance.
RESIDENTIAL AREAS
_ Agricultural Residential
Agricultural Residential lands are located in the rural areas that lie outside of defined Urban Services
Areas in Iredell County and are located in northern Iredell. This classification also includes lands in
southern Iredell County that lie within water supply watershed protection areas where dense
development is discouraged. Agricultural Residential areas will not be serviced by public or private
water or sanitary sewer services during the planning period. Private uses will be served by well water
and septic systems. The intent of these lands is that they will remain rural in character and have a
maximum density of one (1) dwelling unit per two (2) acres. Clustering of residential uses is permitted if
health code septic standards can be met and open space is set aside as part of the subdivision. Uses
within this area generally should include some farming operations, accessory farming uses, single-family
residences, accessory dwelling units, churches, parks, and institutional uses.
Low -Density Residential
_ Low -Density Residential areas include traditional low -density subdivision developments and future low -
density neighborhoods. Lands may be serviced by public or private water and sanitary sewer or private
well and septic systems. These areas are both within and outside the Iredell County Urban Services
Areas. Low -Density Residential lands within the Urban Services Area may be serviced by and
incorporated into one of the municipalities at some point in the future. The intent of these lands is that
they provide a transition in intensity from rural to more urban uses and that they maintain a low -density
_ residential character over time. Uses within this area generally should include single-family residences,
accessory dwelling units, churches, parks, and institutional uses such as schools. Maximum densities
within low -density residential areas should generally be two (2) dwelling units per one (1) acre.
Medium -Density Residential
Medium -Density Residential areas include land that is either currently developed or slated for future
development at medium densities. These areas are within the Iredell County Urban Services Areas and
may be serviced by and incorporated into one of the municipalities at some point in the future. These
lands are either currently served or will be served in the future by public or private water or sanitary
sewer systems. The intent of these lands is that they provide more dense development opportunities
and a broader range of housing choices than low -density residential. Uses within this area generally
should include single-family residences, townhomes, multi -family residential developments, accessory
dwelling units, churches, parks, institutional uses such as schools, and neighborhood -scale commercial
ADOPTED SEPTEMBER 15, 2D09

IREDELL COUNiY
2030 HORIZON PLAN
development. Maximum densities within medium -density residential areas should generally be six (6)
dwelling units per one (1) acre.
High -Density Residential/Mixed-Use
High -Density Residential / Mixed -Use areas are either currently developed or slated for future
development at higher densities, These areas lie within the Iredell County urban services areas and may
., be serviced by and incorporated into one of the municipalities at some point in the future. These lands
are either currently served or will be served in the future by public or private water or sanitary sewer
systems. The intent of these lands is that they provide urban -scale development opportunities and a
broader range of housing choices than medium -density residential. Uses within this area generally
should include single-family residences, townhomes, condominiums, apartments, accessory dwelling
units, age -restricted residential developments, churches, parks, institutional uses, and mixed -use
_ neighborhood -scale commercial development. Secondary uses might include more intense commercial
and office uses that fit with the existing character of the neighborhood. Minimum densities within high -
density residential/mixed-use areas should generally be more than six (6) dwelling units per one (1)
acre. Maximum densities should be comparable to the densities found in neighboring developments
and generally fit the character of the area.
NON-RESIDENTIAL AREAS
Rural Commercial
Rural Commercial areas include existing commercial uses or areas intended for future commercial use
that are located along major roadways in rural areas. The intent of these areas is that they will remain
rural in character for the planning period and will not be serviced by public or private water and sanitary
sewer systems. Land uses appropriate within Rural Commercial areas include supporting farm services,
small-scale commercial uses such as small markets, convenience stores, small neighborhood service
businesses, restaurants, churches, and institutional uses.
_ Transitional Commercial
Transitional Commercial areas include existing neighborhood commercial uses or areas intended for
future commercial use that are adjacent to neighborhoods. These areas provide transitions or buffers
_ between lower intensity residential uses and higher intensity commercial development. The intent of
these areas is that they will continue to serve as a buffer to residential areas and provide local
opportunities for low intensity shopping and office uses. Land uses appropriate within Transitional
Commercial areas include small-scale commercial uses such as small markets, convenience stores, small
�. neighborhood service businesses, small offices, churches, and institutional uses. Secondary uses can
include residential uses.
Corridor Commercial
Corridor Commercial areas include existing commercial, office, and/or retail uses that exist along major
thoroughfares and highways or areas that will include commercial development in the future and can
includes both large and small mixed -use commercial centers. These areas are both within and outside
the Iredell County Urban Services Areas. They may be serviced by and incorporated into one of the
municipalities at some point in the future. -The intent of these lands is to provide a mix of
commercial/retail and office uses at critical nodes or activity centers along major roadways. Traditional
strip commercial development is discouraged within these areas. Instead, developments should be
designed to provide greater connectivity within and to adjacent developments, pedestrian access should
be a priority, and landscaping, signage, and building design and orientation should be consistent within

_ • WS III —low to moderately developed; and
■ WS IV —moderately to highly developed.
In addition to these state regulations, the county
has adopted a development regulation that
requires placement of a 30-foot natural buffer
around all perennial streams.
Water and Wastewater
Iredell County does not provide water and
wastewater services. Its three largest towns —
Mooresville, Statesville, and Troutman — provide
water and sanitary sewer services within defined
service areas. (See the Water and Wastewater
Service Areas Map in Appendix B and on the next
page.) Other areas not provided with public water
and sanitary sewer service are served by well water
and private septic systems or one of five private
water / sewage treatment companies.

Mooresville — Water and Wastewater Water supply watersheds are protected in Iredell
Mooresville adopted a Water and Wastewater County bystate regulations.
Master Plan in 2006. It includes plans for expansion
in incremental stages as denoted on the map on the next page. The plans for service area expansion
through 2010, 2015, and beyond 2025 represent the general expectations for expansion of service
during these time periods. Future growth in the service area was estimated based on the 2003
population study conducted by Warren & Associates. Extensions of service are typically developer
driven and most are not planned for through the town's Capital Improvement Plan (CIP), but new
infrastructure is publicly owned. The town requests voluntary annexations as a precursor to extension
of service and usually requests planning and zoning authority from the county prior to annexation of
new lands; this is decided on a case -by -case basis.
Due to the fact that the system is currently experiencing constraints on capacity because of the state's
requirement that utilities have capacity in reserve for pending projects, the town is updating its master
plan in 2009. The town is also evaluating expansion opportunities.
The utility operates two main treatment facilities: the water treatment plant on US-21 and the
wastewater treatment plant on Johnson Dairy Road. Water service is provided to 1,801 commercial
customers and 10,037 residential customers. Wastewater service is provided to 1,457 commercial
customers and 10,085 residential customers.
Mooresville's water treatment is 6.OMGD (million gallons per day). A new 12MGD water treatment plant
is currently under construction. After completion of the project, the total treatment capacity will be
18MGD. The average daily flow is 3.8MGD and the maximum daily flow is 6.OMGD. Average water
usage per unit is 900GPD (gallons per day) for commercial users, and 150GPD for residential users.

15A NCAC 02T .0114 WASTEWATER DESIGN FLOW RATES
(a) This Rule shall be used to determine wastewater flow rates for all systems covered by this Subchapter unless
alternate criteria are provided by a program specific rule and for flow used for the purposes of 15A NCAC 02H .0105.
These are minimum design daily flow rates for normal use and occupancy situations. Higher flow rates may be required
where usage and occupancy are atypical, including, those in Paragraph (e) of this Rule. Wastewater flow calculations
must take hours of operation and anticipated maximum occupancies/usage into account when calculating peak flows for
design.
(b) In determining the volume of sewage from dwelling units, the flow rate shall be 120 gallons per day per bedroom.
The minimum volume of sewage from each dwelling unit shall be 240 gallons per day and each additional bedroom
above two bedrooms shall increase the volume by 120 gallons per day. Each bedroom or any other room or addition that
can reasonably be expected to function as a bedroom shall be considered a bedroom for design purposes. When the
occupancy of a dwelling unit exceeds two persons per bedroom, the volume of sewage shall be determined by the
maximum occupancy at a rate of 60 gallons per person per day.
(c) The following table shall be used to determine the minimum allowable design daily flow of wastewater facilities.
Design flow rates for establishments not identified below shall be determined using available flow data, water -using
fixtures, occupancy or operation patterns, and other measured data.

(d) Design daily flow rates for proposed non-residential developments where the types of use and occupancy are not
known shall be designed for a minimum of 880 gallons per acre or the applicant shall specify an anticipated flow based
upon anticipated or potential uses.
(e) Conditions applicable to the use of the above design daily flow rates:
(1) For restaurants, convenience stores, service stations and public access restroom facilities, higher
design daily flow rates shall be required based on higher expected usage where use is increased
because of its proximity to highways, malls, beaches, or other similar high use areas.
(2) Residential property on barrier islands and similar communities located south or east of the Atlantic
.. Intracoastal Waterway used as vacation rental as defined in G.S. 42A-4 shall use 120 gallons per day
per habitable room. Habitable room shall mean a room or enclosed floor space used or intended to be
used for living or sleeping, excluding kitchens and dining areas, bathrooms, shower rooms, water
closet compartments, laundries, pantries, foyers, connecting corridors, closets, and storage spaces.
(f) An adjusted daily sewage flow design rate shall be granted for permitted but not yet tributary connections and future
connections tributary to the system upon showing that a sewage system is adequate to meet actual daily wastewater flows
from a facility included in Paragraph (b) or (c) of this Rule without causing flow violations at the receiving wastewater
treatment plant or capacity related sanitary sewer overflows within the collection system as follows:
(1) Documented, representative data from that facility or a comparable facility shall be submitted by an
authorized signing official in accordance with Rule .0106 ofthis Section to the Division as follows for
all flow reduction request:
(A) Dates of flow meter calibrations during the time frame evaluated and indication if any
adjustments were necessary.
(B) A breakdown of the type of connections (e.g. two bedroom units, three bedroom units) and
number of customers for each month of submitted data as applicable. Identification of any
non-residential connections including subdivision clubhouses/pools, restaurants, schools,
churches and businesses. For each non-residential connection, information as identified in
Paragraph (c) of this Rule (e.g. 200 seat church, 40 seat restaurant, 35 person pool
bathhouse).
(C) Owner of the collection system.
(D) Age of the collection system.
(E) Analysis of inflow and infiltration within the collection system or receiving treatment plant,
as applicable.
(F) Where a dedicated wastewater treatment plant serves the specific area and is representative
of the residential wastewater usage, at least the 12 most recent consecutive monthly average
wastewater flow readings and the daily total wastewater flow readings for the highest
average wastewater flow month per customers as reported to the Division.
(G) Where daily data from a wastewater treatment plant cannot be utilized or is not representative
of the project area: at least 12 months worth of monthly average wastewater flows from the
receiving treatment plant shall be evaluated to determine the peak sewage month. Daily
wastewater flows shall then be taken from a flow meter installed at the most downstream
point of the collection area for the peak month selected that is representative of the project
area. Justification for the selected placement of the flow meter shall also be provided.
(H) An estimated minimum design daily sewage flow rate shall be taken by calculating the
numerical average of the top three daily readings for the highest average flow month. The
calculations shall also account for seasonal variations, excessive inflow and infiltration, age
and suspected meter reading/recording errors.
(2) The Division shall evaluate all data submitted but shall also consider other factors in granting, with or
without adjustment, or denying a flow reduction request including: applicable weather conditions
during the data period (i.e. rainy or drought), other historical monitoring data for the particular facility
or other similar facilities available to the Division, the general accuracy of monitoring reports and flow
A. meter readings, and facility usage (i.e., resort area).
(3) Flow increases shall be required if the calculations in Subparagraph (f)(1) of this Rule yield design
flows higher than that specified in Paragraphs (b) or (c) of this Rule.
(4) The applicant/owner shall retain the letter of any approved adjusted daily design flow rate for the life
of the facility and shall transfer such letter to any new system owner.

An adjusted daily sewage flow may be granted upon a showing that a sewage system is
adequate to meet actual daily water consumption from a facility included in
Subparagraph (1) or (2) of this Paragraph. Documented, representative data from that
facility or a comparable facility shall be submitted, consisting of at least 12 consecutive
monthly total water consumption readings and daily total water consumption readings for
at least 30 consecutive days of water use. The daily readings shall be taken during a
projected peak sewage flow month. The adjusted design daily sewage flow shall be
determined by taking the numerical average of the daily readings that fall within the
upper 10 percent of the daily readings when ranked in descending order.
(m) For Treatment and Disposal of Soil Containing Petroleum Products:
(1)
Laridfarming of Soils Containing Petroleum Products at Minimum Rates. Petroleum
contaminated soils shall be incorporated into the native soils of the receiver site
°^
immediately upon application. Liming, fertilization, and aeration of the soils mixture
shall be optional, unless otherwise required by the Division. Subsequent application of
petroleum contaminated soils onto the same receiver site shall not occur for at least 18
months from the date of the most recent application of petroleum contaminated soils and
shall cause the receiver site to be reclassified as a "dedicated remediation site" unless the
permittee or applicant can demonstrate, through soil sampling and contaminant analytical
procedures approved by the Department, that the petroleum contaminant level in the
upper eight inches of the receiver site soils is below analytical detection levels;
(2)
Landfarming of Soil Containing Petroleum Products at Conventional Rates.
Landfarming of soils containing petroleum product at an application thickness greater
than one inch shall require fertilization, liming, and aeration of the native soils and
petroleum contaminated soils mixture as approved by the Division. Application
thickness shall be based upon the nature of the receiver site soils, depth to the seasonal
high water table, the intended cover crop, and the source of contamination, in accordance
with procedures approved by the Division. Operation of the landfarming program shall
not result in contravention of classified groundwater or surface water quality standards.
Subsequent application of petroleum contaminated soils onto the same receiver site shall
not occur for at least 18 months from the date of the most recent application of petroleum
contaminated soils and shall cause the receiver site to be reclassified as a "dedicated
disposal site" unless the permittee or applicant can demonstrate, through soil sampling
and contaminant analytical procedures approved by the Department, that the petroleum
contaminant level in the upper eight inches of the receiver site soils is below analytical
detection levels;
(3)
Containment and Treatment of Soil Containing Petroleum Products:
(A) A containment structure designed to bioremediate or volatilize soil containing
petroleum products shall be constructed of either a synthetic liner of at least 30
mils thickness or of a one foot thick liner of natural material, compacted to at
least 95 percent standard proctor dry density and with a permeability of less than
1 x 10'7 cm/sec.
a..
(B) The bottom of the containment structure shall be at least three feet above the
seasonal high water table or bedrock.
(C) A leachate collection system must be installed in order to prevent runoff from
the petroleum contaminated soils within the containment structure, or steps
taken to avoid accumulation of stormwater within the containment structure.
(4)
Disposal of Petroleum Contaminated Soils at Dedicated Sites. Subsequent applications
of petroleum contaminated soils at dedicated sites shall not recur until such time as it can
