INTRODUCTION
This report has been prepared in accordance with the Settlement Agreement signed on
December 3, 2010, reached between the states of South Carolina and North Carolina,
Duke Energy Carolinas LLC, and the Catawba River Water Supply Project. As a condition
of that agreement, "each State shall prepare an annual report of the average daily
transfer amounts for each entity holding an [Interbasin Transfer] IBT certificate and
provide it to the other State." This annual report, which is a summary of IBTs to and
from the Catawba River Basin that are conducted by IBT certificate holders within North
Carolina, serves as North Carolina's annual report in accordance with the settlement
agreement.
BACKGROUND: IBT LAW IN NORTH CAROLINA
In 1993, the North Carolina Legislature enacted General Statute G.S. §143-215.22I as
part of An Act to Regulate Interbasin Transfers (Session Law 1993-348). This law
regulated large surface water transfers between river basins by requiring a certificate
from the Environmental Management Commission (EMC). Following General Statute
G.S. §143-215.221, a transfer certificate was required for new surface water transfers of
2.0 million gallons per day (MGD) or more.
Due to the fact that the Surface Water Transfer Act was first adopted in 1993, many of
the IBT rules and requirements reference a system's daily flows and capacity at that
time. Facilities that were in existence prior to 1993 are said to have Grandfathered
Transfers up to either 25 percent above their average daily flow at that time, their
maximum system capacity at that time, or 2 MGD - whichever is greater. If a facility
existed or was under construction by July 1, 1993, a certificate is not required up to the
full capacity of that facility to transfer water, regardless of the transfer amount.
An important point in North Carolina's IBT law is that it creates its own, specific
definition of a "river basin." According to G.S. §143-215.22G, there are 38 designated
river basins. An IBT certificate is required for any transfer, meeting the statutorily
defined thresholds, between any of these defined river basins. Figure 1 illustrates the
designated river basins.

The current procedure for obtaining an IBT Certificate is specifically laid out in
G.S. § 143-215.22L. The full process can take three to five years (or more), requires local
and interstate notification, and offers a number of opportunities for public comment
and review. The passage in 2013 of Session Law 2013-388 changed the way in which a
proposed IBT is calculated, among other revisions. Instead of a maximum daily transfer,
the revised calculation is based on an average daily transfer calculated over a calendar
month. Even though the statistical calculation was changed, the 2.0 MGD threshold
remained the same. The full text of IBT statute §143-215.22L is included as Appendix A
in this report. Previous IBT statutes are available on the Division of Water Resources
(DWR) website at: DWR IBT Rules & Regulations.
As of September 2024, the North Carolina EMC has issued nine IBT certificates. Two of
these certificates directly affect the Catawba River Basin. Those two certificates,
Charlotte Water (formerly Charlotte Mecklenburg Utilities) and the Cities of Concord
and Kannapolis, are further discussed in this report. Throughout North Carolina there
are approximately 130 water systems that have surface water transfers, most of which
transfer less than 2.0 MGD on a maximum day basis. These water systems are not
required to obtain an IBT certificate until they exceed the statutory thresholds. Since
these systems are not required to obtain an IBT certificate, they are not discussed in this
document.

CHARLOTTE WATER
Charlotte Water, formerly Charlotte Mecklenburg Utilities, has held an IBT certificate
since March 14, 2002. The certificate allows Charlotte Water to transfer up to 33.0
MGD from the Catawba River Basin to the Rocky River basin. Figure 2 illustrates
Charlotte Water's two water intakes (identified by yellow stars) in the Catawba River
basin, and five wastewater treatment plants (identified by red stars) throughout the
Catawba and Rocky River basins. The utility pursued this certificate to meet projected
demands through 2030 in eastern Mecklenburg County. Specific details of Charlotte
Water's service area and sales are included in Appendix B, Charlotte Water 2023 IBT
Annual Report.

In May 2013, Charlotte Water was granted a modification to the original IBT Certificate
from the EMC, which removed Condition 3 from the Certificate. Condition 3 stated that,
"the Goose Creek subbasin in Mecklenburg County is removed from the area to be served
by the IBT. A moratorium on the installation of new interbasin transfer water lines
(water lines crossing the ridgeline) into Goose Creek subbasin is in effect until the
impacts of additional urban growth on the endangered species are fully evaluated." This
condition was removed after the EMC determined that the Town of Mint Hill's 2010
Post -Construction Ordinance (PCO) permanently implemented appropriate mitigation
measures for impacts to the Carolina Heelsplitter (Lasmigona decorata) in the Goose
Creek watershed. Removal of this condition allows Charlotte Water to provide water
service to customers in the Goose Creek watershed.
Charlotte Water provides water to retail customers in the Rocky River basin, including
customers in the City of Concord and Town of Harrisburg, in neighboring Cabarrus
County. Charlotte Water can transfer treated potable water to the Town of Harrisburg
through two metered connections to their water system. Harrisburg's service area is
entirely within the Rocky River basin and is included in Charlotte Water's IBT amounts.
Water is only provided to Concord as an emergency backup to Concord's primary supply
consisting of Lake Howell and several smaller reservoirs. All of these reservoirs are
within the Rocky River basin. The Cities of Concord and Kannapolis received an IBT
Certificate in January 2007 for the transfer of up to 10.0 MGD from the Catawba River
basin to the Rocky River basin; therefore, any water sold to Concord is not applied to
Charlotte Water's IBT amount.
Charlotte Water's IBT calculation methodology was approved by DWR in June 2006. Per
the certificate, Charlotte Water reports the maximum daily IBT amounts annually to
DWR until such time as the transfer amount exceeds 80 percent of the authorized
amount. Once that amount is exceeded, Charlotte Water is required to report monthly.
To date, Charlotte Water has not exceeded 80 percent of the authorized IBT amount.
Charlotte Water's IBT certificate requires an annual report listing the maximum daily
transfer for the calendar year. The average daily and maximum daily transfers for 2023
are presented below in Table 1. Charlotte Water's 2023 IBT annual report is included in
Appendix B. Annual reports from 2002-2023 are available on the division's website at,
Charlotte Water IBT Page.

CONCORD AND KANNAPOLIS
The Cities of Concord and Kannapolis (the cities) have held an IBT certificate since
January 2007. This certificate authorizes the transfer of up to 10.0 MGD from the
Catawba River basin to the Rocky River basin and 10.0 MGD from the Yadkin River basin
to the Rocky River basin. These amounts were authorized based on the cities' needs
through 2035 and an analysis of the yield of available water sources. In addition, the
cities have a grandfathered transfer capacity (based on infrastructure in place prior to
1993) of 6.0 MGD from the South Yadkin River basin to the Rocky River basin. Figure 3
illustrates the cities' service area and interbasin transfers. Specific details of the cities'
service area and sales are included in Appendix C, Concord and Kannapolis' 2023 IBT
Annual Report.
Figure 3: Concord and Kannapolis Service Area
In 2010, the cities reached a settlement in a lawsuit filed by the Catawba River
Foundation, Inc., and the Protect the Catawba Coalition. While this settlement
agreement does not affect the IBT Certificate, its conditions, or required reporting, the
5

cities did agree to several operational conditions in the Catawba River basin. Until July 1,
2015, the cities agreed to transfer no more than 3.0 MGD (on a maximum day basis)
from the Catawba River basin. Thereafter, the cities must first transfer 5.0 MGD from
the Yadkin River basin before exceeding an IBT of 3.0 MGD from the Catawba River
basin. During designated droughts beyond July 1, 2015, following either Low Inflow
Protocol (LIP) or Drought Management Advisory Council (DMAC) Drought Stage
declaration, the cities have agreed to limit the Catawba River basin IBT so that it
corresponds to water use reduction goals. Further details about this agreement,
including the water use reduction goals after July 2015, can be found in Appendix C.
The cities' IBT certificate requires an annual report listing the maximum daily transfer
for the calendar year. The average daily and maximum daily transfers for 2023 are
summarized below in Table 2.

Certificate. No value listed is effectively zero.
In 2023, the maximum day IBT from the Catawba River Basin was 3.579 MGD, which
represents 35.8 percent of the permitted maximum day transfer of 10 MGD under the
IBT Certificate approved by the EMC in January 2007. The maximum day IBT from the
Yadkin River Basin during the calendar year 2023 was 5.16 MGD, which represents 51.6
percent of the permitted maximum day of 10 MGD IBT from the Yadkin River Basin
under the IBT Certificate.
The average day IBT from the Catawba River Basin was 0.014 MGD, which represents
0.14 percent of the permitted maximum day transfer of 10 MGD. The average day IBT
from the Yadkin River Basin was 4.48 MGD, which represents 44.8 percent of the
permitted maximum day transfer of 10 MGD. There was a transfer of raw water from
Second Creek with a maximum day of -0.172 MGD, which represents -2.87 percent of
the allowable maximum day transfer of 6 MGD from the South Yadkin River Basin under
the grandfathered transfer. The 2023 annual report is included in Appendix C. Annual
reports from 2007-2023 are available on the division's website at, Concord & Kannapolis
IBT Page.

CONCLUSION
Based on the information previously discussed in this report, the Division of Water
Resources estimates that IBT certificate holders transferred approximately 20.43 MGD,
on an average daily basis, from the Catawba River basin in 2023. On a maximum day
basis, approximately 29.82 MGD was transferred from the Catawba River basin in 2023.
None of the transfers from the Catawba River basin exceeded 80 percent of the
allowable transfer; therefore, annual reports will continue to be the required
monitoring procedure.

(3) A description of measures to mitigate any adverse impacts that may arise
from the proposed interbasin transfer.
(e) Public Hearing on the Draft Environmental Document. — The Commission shall
hold a public hearing on the draft environmental document for a proposed interbasin transfer
after giving at least 30 days' written notice of the hearing in the Environmental Bulletin and as
provided in subdivisions (2) and (3) of subsection (c) of this section. The notice shall indicate
where a copy of the environmental document can be reviewed and the procedure to be followed
by anyone wishing to submit written comments and questions on the environmental document.
The Commission shall prepare a record of all comments and written responses to questions
posed in writing. The record shall include complete copies of scientific or technical comments
related to the potential impact of the interbasin transfer. The Commission shall accept written
comment on the draft environmental document for a minimum of 30 days following the last
public hearing. The applicant who petitions the Commission for a certificate under this section
shall pay the costs associated with the notice and public hearing on the draft environmental
document.
(f) Determination of Adequacy of Environmental Document. — The Commission shall
not act on any petition for an interbasin transfer until the Commission has determined that the
environmental document is complete and adequate. A decision on the adequacy of the
environmental document is subject to review in a contested case on the decision of the
Commission to issue or deny a certificate under this section.
(g) Petition. — An applicant for a certificate shall petition the Commission for the
certificate. The petition shall be in writing and shall include all of the following:
(1) A general description of the facilities to be used to transfer the water,
including current and projected areas to be served by the transfer, current
and projected capacities of intakes, and other relevant facilities.
(2) A description of all the proposed consumptive and nonconsumptive uses of
the water to be transferred.
(3) A description of the water quality of the source river and receiving river,
including information on aquatic habitat for rare, threatened, and endangered
species; in -stream flow data for segments of the source and receiving rivers
that may be affected by the transfer; and any waters that are impaired
pursuant to section 303(d) of the federal Clean Water Act (33 U.S.C. §
1313(d)).
(4) A description of the water conservation measures used by the applicant at
the time of the petition and any additional water conservation measures that
the applicant will implement if the certificate is granted.
(5) A description of all sources of water within the receiving river basin,
including surface water impoundments, groundwater wells, reinjection
storage, and purchase of water from another source within the river basin,
that is a practicable alternative to the proposed transfer that would meet the
applicant's water supply needs. The description of water sources shall
include sources available at the time of the petition for a certificate and any
planned or potential water sources.
(6) A description of water transfers and withdrawals registered under G.S.
143-215.22H or included in a local water supply plan prepared pursuant to
G.S. 143-355(1) from the source river basin, including transfers and
withdrawals at the time of the petition for a certificate and any planned or
reasonably foreseeable transfers or withdrawals by a public water system
with service area located within the source river basin.
G.S. 143-215.22L Page 4

(7) A demonstration that the proposed transfer, if added to all other transfers and
withdrawals required to be registered under G.S. 143-215.22H or included in
any local water supply plan prepared by a public water system with service
area located within the source basin pursuant to G.S. 143-355(1) from the
source river basin at the time of the petition for a certificate, would not
reduce the amount of water available for use in the source river basin to a
degree that would impair existing uses, pursuant to the antidegradation
policy set out in 40 Code of Federal Regulation § 131.12 (Antidegradation
Policy) (1 July 2006 Edition) and the statewide antidegradation policy
adopted pursuant thereto, or existing and planned consumptive and
nonconsumptive uses of the water in the source river basin. If the proposed
transfer would impact a reservoir within the source river basin, the
demonstration must include a finding that the transfer would not result in a
water level in the reservoir that is inadequate to support existing uses of the
reservoir, including recreational uses.
(8) The applicant's future water supply needs and the present and reasonably
foreseeable future water supply needs for public water systems with service
area located within the source river basin. The analysis of future water
supply needs shall include agricultural, recreational, and industrial uses, and
electric power generation. Local water supply plans prepared pursuant to
G.S. 143-355(1) for water systems with service area located within the
source river basin shall be used to evaluate the projected future water needs
in the source river basin that will be met by public water systems.
(9) The applicant's water supply plan prepared pursuant to G.S. 143-355(1). If
the applicant's water supply plan is more than two years old at the time of
the petition, then the applicant shall include with the petition an updated
water supply plan.
(10) Any other information deemed necessary by the Commission for review of
the proposed water transfer.
(h) Settlement Discussions. — Upon the request of the applicant, any interested party, or
the Department, or upon its own motion, the Commission may appoint a mediation officer. The
mediation officer may be a member of the Commission, an employee of the Department, or a
neutral third party but shall not be a hearing officer under subsections (e) or (j) of this section.
The mediation officer shall make a reasonable effort to initiate settlement discussions between
the applicant and all other interested parties. Evidence of statements made and conduct that
occurs in a settlement discussion conducted under this subsection, whether attributable to a
party, a mediation officer, or other person shall not be subject to discovery and shall be
inadmissible in any subsequent proceeding on the petition for a certificate. The Commission
may adopt rules to govern the conduct of the mediation process.
(i) Draft Determination. — Within 90 days after the Commission determines that the
environmental document prepared in accordance with subsection (d) of this section is adequate
or the applicant submits its petition for a certificate, whichever occurs later, the Commission
shall issue a draft determination on whether to grant the certificate. The draft determination
shall be based on the criteria set out in this section and shall include the conditions and
limitations, findings of fact, and conclusions of law that would be required in a final
determination. Notice of the draft determination shall be given as provided in subsection (c) of
this section.
(j) Public Hearing on the Draft Determination. — Within 60 days of the issuance of the
draft determination as provided in subsection (i) of this section, the Commission shall hold
public hearings on the draft determination. At least one hearing shall be held in the affected
G.S. 143-215.22L Page 5

area of the source river basin, and at least one hearing shall be held in the affected area of the
receiving river basin. In determining whether more than one public hearing should be held
within either the source or receiving river basins, the Commission shall consider the differing
or conflicting interests that may exist within the river basins, including the interests of both
upstream and downstream parties potentially affected by the proposed transfer. The public
hearings shall be conducted by one or more hearing officers appointed by the Chair of the
Commission. The hearing officers may be members of the Commission or employees of the
Department. The Commission shall give at least 30 days' written notice of the public hearing as
provided in subsection (c) of this section. The Commission shall accept written comment on the
draft determination for a minimum of 30 days following the last public hearing. The
Commission shall prepare a record of all comments and written responses to questions posed in
writing. The record shall include complete copies of scientific or technical comments related to
the potential impact of the interbasin transfer. The applicant who petitions the Commission for
a certificate under this section shall pay the costs associated with the notice and public hearing
on the draft determination.
(k) Final Determination: Factors to be Considered. — In determining whether a
certificate may be issued for the transfer, the Commission shall specifically consider each of
the following items and state in writing its findings of fact and conclusions of law with regard
to each item:
(1) The necessity and reasonableness of the amount of surface water proposed to
be transferred and its proposed uses.
(2) The present and reasonably foreseeable future detrimental effects on the
source river basin, including present and future effects on public, industrial,
economic, recreational, and agricultural water supply needs, wastewater
assimilation, water quality, fish and wildlife habitat, electric power
generation, navigation, and recreation. Local water supply plans for public
water systems with service area located within the source river basin
prepared pursuant to G.S. 143-355(1) shall be used to evaluate the projected
future water needs in the source river basin that will be met by public water
systems. Information on projected future water needs for public water
systems with service area located within the source river basin that is more
recent than the local water supply plans may be used if the Commission
finds the information to be reliable. The determination shall include a
specific finding as to measures that are necessary or advisable to mitigate or
avoid detrimental impacts on the source river basin.
(3) The cumulative effect on the source major river basin of any water transfer
or consumptive water use that, at the time the Commission considers the
petition for a certificate is occurring, is authorized under this section, or is
projected in any local water supply plan for public water systems with
service area located within the source river basin that has been submitted to
the Department in accordance with G.S. 143-355(1).
(4) The present and reasonably foreseeable future beneficial and detrimental
effects on the receiving river basin, including present and future effects on
public, industrial, economic, recreational, and agricultural water supply
needs, wastewater assimilation, water quality, fish and wildlife habitat,
electric power generation, navigation, and recreation. Local water supply
plans prepared pursuant to G.S. 143-355(1) that affect the receiving river
basin shall be used to evaluate the projected future water needs in the
receiving river basin that will be met by public water systems. Information
on projected future water needs that is more recent than the local water
G.S. 143-215.22L Page 6

supply plans may be used if the Commission finds the information to be
reliable. The determination shall include a specific finding as to measures
that are necessary or advisable to mitigate or avoid detrimental impacts on
the receiving river basin.
(5) The availability of reasonable alternatives to the proposed transfer, including
the potential capacity of alternative sources of water, the potential of each
alternative to reduce the amount of or avoid the proposed transfer, probable
costs, and environmental impacts. In considering alternatives, the
Commission is not limited to consideration of alternatives that have been
proposed, studied, or considered by the applicant. The determination shall
include a specific finding as to why the applicant's need for water cannot be
satisfied by alternatives within the receiving basin, including unused
capacity under a transfer for which a certificate is in effect or that is
otherwise authorized by law at the time the applicant submits the petition.
The determination shall consider the extent to which access to potential
sources of surface water or groundwater within the receiving river basin is
no longer available due to depletion, contamination, or the declaration of a
capacity use area under Part 2 of Article 21 of Chapter 143 of the General
Statutes. The determination shall consider the feasibility of the applicant's
purchase of water from other water suppliers within the receiving basin and
of the transfer of water from another sub -basin within the receiving major
river basin. Except in circumstances of technical or economic infeasibility or
adverse environmental impact, the Commission's determination as to
reasonable alternatives shall give preference to alternatives that would
involve a transfer from one sub -basin to another within the major receiving
river basin over alternatives that would involve a transfer from one major
river basin to another major river basin.
(6) If applicable to the proposed project, the applicant's present and proposed
use of impoundment storage capacity to store water during high -flow periods
for use during low -flow periods and the applicant's right of withdrawal under
G.S. 143-215.44 through G.S. 143-215.50.
(7) If the water to be withdrawn or transferred is stored in a multipurpose
reservoir constructed by the United States Army Corps of Engineers, the
purposes and water storage allocations established for the reservoir at the
time the reservoir was authorized by the Congress of the United States.
(8) Whether the service area of the applicant is located in both the source river
basin and the receiving river basin.
(9) Any other facts and circumstances that are reasonably necessary to carry out
the purposes of this Part.
(1) Final Determination: Information to be Considered. — In determining whether a
certificate may be issued for the transfer, the Commission shall consider all of the following
sources of information:
(1) The petition.
(2) The environmental document prepared pursuant to subsection (d) of this
section.
(3) All oral and written comment and all accompanying materials or evidence
submitted pursuant to subsections (e) and (j) of this section.
(4) Information developed by or available to the Department on the water
quality of the source river basin and the receiving river basin, including
waters that are identified as impaired pursuant to section 303(d) of the
G.S. 143-215.22L Page 7

federal Clean Water Act (33 U.S.C. § 1313(d)), that are subject to a total
maximum daily load (TMDL) limit under subsections (d) and (e) of section
303 of the federal Clean Water Act, or that would have their assimilative
capacity impaired if the certificate is issued.
(5) Any other information that the Commission determines to be relevant and
useful.
(m) Final Determination: Burden and Standard of Proof; Specific Findings. — The
Commission shall grant a certificate for a water transfer if the Commission finds that the
applicant has established by a preponderance of the evidence all of the following:
(1) The benefits of the proposed transfer outweigh the detriments of the
proposed transfer. In making this determination, the Commission shall be
guided by the approved environmental document and the policy set out in
subsection (t) of this section.
(2) The detriments have been or will be mitigated to the maximum degree
practicable.
(3) The amount of the transfer does not exceed the amount of the projected
shortfall under the applicant's water supply plan after first taking into
account all other sources of water that are available to the applicant.
(4) There are no reasonable alternatives to the proposed transfer.
(n) Final Determination: Certificate Conditions and Limitations. — The Commission
may grant the certificate in whole or in part, or deny the certificate. The Commission may
impose any conditions or limitations on a certificate that the Commission finds necessary to
achieve the purposes of this Part including a limit on the period for which the certificate is
valid. The conditions and limitations shall include any mitigation measures proposed by the
applicant to minimize any detrimental effects within the source and receiving river basins. In
addition, the certificate shall require all of the following conditions and limitations:
(1) A water conservation plan that specifies the water conservation measures
that will be implemented by the applicant in the receiving river basin to
ensure the efficient use of the transferred water. Except in circumstances of
technical or economic infeasibility or adverse environmental impact, the
water conservation plan shall provide for the mandatory implementation of
water conservation measures by the applicant that equal or exceed the most
stringent water conservation plan implemented by a public water system that
withdraws water from the source river basin.
(2) A drought management plan that specifies how the transfer shall be managed
to protect the source river basin during drought conditions or other
emergencies that occur within the source river basin. Except in
circumstances of technical or economic infeasibility or adverse
environmental impact, this drought management plan shall include
mandatory reductions in the permitted amount of the transfer based on the
severity and duration of a drought occurring within the source river basin
and shall provide for the mandatory implementation of a drought
management plan by the applicant that equals or exceeds the most stringent
water conservation plan implemented by a public water system that
withdraws water from the source river basin.
(3) The maximum amount of water that may be transferred, calculated as a daily
average of a calendar month, and methods or devices required to be installed
and operated that measure the amount of water that is transferred.
(4) A provision that the Commission may amend a certificate to reduce the
maximum amount of water authorized to be transferred whenever it appears
G.S. 143-215.22L Page 8

that an alternative source of water is available to the certificate holder from
within the receiving river basin, including, but not limited to, the purchase of
water from another water supplier within the receiving basin or to the
transfer of water from another sub -basin within the receiving major river
basin.
(5) A provision that the Commission shall amend the certificate to reduce the
maximum amount of water authorized to be transferred if the Commission
finds that the applicant's current projected water needs are significantly less
than the applicant's projected water needs at the time the certificate was
granted.
(6) A requirement that the certificate holder report the quantity of water
transferred during each calendar quarter. The report required by this
subdivision shall be submitted to the Commission no later than 30 days after
the end of the quarter.
(7) Except as provided in this subdivision, a provision that the applicant will not
resell the water that would be transferred pursuant to the certificate to
another public water system. This limitation shall not apply in the case of a
proposed resale or transfer among public water systems within the receiving
river basin as part of an interlocal agreement or other regional water supply
arrangement, provided that each participant in the interlocal agreement or
regional water supply arrangement is a co -applicant for the certificate and
will be subject to all the terms, conditions, and limitations made applicable
to any lead or primary applicant.
(o) Administrative and Judicial Review. — Administrative and judicial review of a final
decision on a petition for a certificate under this section shall be governed by Chapter 150B of
the General Statutes.
(p) Certain Preexisting Transfers. — In cases where an applicant requests approval to
increase a transfer that existed on 1 July 1993, the Commission may approve or disapprove
only the amount of the increase. If the Commission approves the increase, the certificate shall
be issued for the amount of the preexisting transfer plus any increase approved by the
Commission. A certificate for a transfer approved by the Commission under G.S. 162A-7 shall
remain in effect as approved by the Commission and shall have the same effect as a certificate
issued under this Part. A certificate for the increase of a preexisting transfer shall contain all of
the conditions and limitations required by subsection (m) of this section.
(q) Emergency Transfers. — In the case of water supply problems caused by drought, a
pollution incident, temporary failure of a water plant, or any other temporary condition in
which the public health, safety, or welfare requires a transfer of water, the Secretary of
Environmental Quality may grant approval for a temporary transfer. Prior to approving a
temporary transfer, the Secretary shall consult with those parties listed in subdivision (3) of
subsection (c) of this section that are likely to be affected by the proposed transfer. However,
the Secretary shall not be required to satisfy the public notice requirements of this section or
make written findings of fact and conclusions of law in approving a temporary transfer under
this subsection. If the Secretary approves a temporary transfer under this subsection, the
Secretary shall specify conditions to protect other water users. A temporary transfer shall not
exceed six months in duration, but the approval may be renewed for a period of six months by
the Secretary based on demonstrated need as set forth in this subsection.
(r) Relationship to Federal Law. — The substantive restrictions, conditions, and
limitations upon surface water transfers authorized in this section may be imposed pursuant to
any federal law that permits the State to certify, restrict, or condition any new or continuing
transfers or related activities licensed, relicensed, or otherwise authorized by the federal
G.S. 143-215.22L Page 9

government. This section shall govern the transfer of water from one river basin to another
unless preempted by federal law.
(s) Planning Requirements. — When any transfer for which a certificate was issued
under this section equals or exceeds eighty percent (80%) of the maximum amount authorized
in the certificate, the applicant shall submit to the Department a detailed plan that specifies how
the applicant intends to address future foreseeable water needs. If the applicant is required to
have a local water supply plan, then this plan shall be an amendment to the local water supply
plan required by G.S.143-355(1). When the transfer equals or exceeds ninety percent (90%) of
the maximum amount authorized in the certificate, the applicant shall begin implementation of
the plan submitted to the Department.
(t) Statement of Policy. — It is the public policy of the State to maintain, protect, and
enhance water quality within North Carolina. It is the public policy of this State that the
reasonably foreseeable future water needs of a public water system with its service area located
primarily in the receiving river basin are subordinate to the reasonably foreseeable future water
needs of a public water system with its service area located primarily in the source river basin.
Further, it is the public policy of the State that the cumulative impact of transfers from a source
river basin shall not result in a violation of the antidegradation policy set out in 40 Code of
Federal Regulations § 131.12 (1 July 2006 Edition) and the statewide antidegradation policy
adopted pursuant thereto.
(u) Repealed by Session Laws 2013-388, s. 2, effective August 23, 2013.

Appendix B:
Charlotte Water's 2023 IBT Annual Report
9

CHARLOTTE
W6TER
Charlotte Water
Annual Report on Interbasin Transfer
Calendar Year 2023
INTRODUCTION
An interbasin transfer (IBT) Certificate was issued on March 14, 2002, that authorizes Charlotte
Water (CLTWater) to transfer up to 33 million gallons per day (mgd) between the river basins.
The IBT Certificate requires CLTWater to report maximum daily IBT amounts annually to the
North Carolina Division of Water Resources (NC DWR).
SYSTEM OVERVIEW
CLTWater operates the water and wastewater systems that serve Charlotte, Cornelius, Davidson,
Huntersville, Mint Hill, Matthews, Pineville, and much of the unincorporated areas of
Mecklenburg County. This system is divided between two river basins designated by NC General
Statutes for regulation of IBT water. The western portion of the system is within the Catawba River
Basin and the eastern portion is within the Rocky River Basin. Water transferred from the Catawba
River Basin to the Rocky River Basin that is not returned to the Catawba river basin is regulated
IBT.
Water for distribution to CLTWater's customers is withdrawn from the Catawba River basin at
two locations. An intake at Lake Norman sends water to the Lee S. Dukes Water Treatment Plant.
A second intake at Mountain Island Lake sends water to the Walter M. Franklin Water Treatment
Plant and to the Vest Water Treatment Plant. Potable water from these three plants is delivered
through an interconnected distribution system to retail customers throughout CLTWater's service
area in Mecklenburg County and in small areas of Iredell, Cabarrus, and Union Counties.
CLTWater also provides wholesale water to municipal systems for resale including: City of
Concord (NC), Town of Harrisburg (NC), Union County (NC), Lancaster County Water and Sewer
District (SC), and York County (SC).
CLTWater treats wastewater at five advanced wastewater treatment plants (WWTP's) that
discharge into small streams in Mecklenburg County. Four of the streams are tributary to the
Catawba River Basin and one (Mallard Creek) is tributary to the Rocky River Basin. CLTWater
also conveys wastewater generated in portions of Mecklenburg County to the Rocky River
Regional Wastewater Treatment Plant (RRRWWTP) operated by the Water and Sewer Authority
of Cabarrus County (WSACC). The RRRWWTP discharges treated effluent to the Rocky River.
To help reduce future IBT, CLTWater is currently constructing a lift station that will be capable
of pumping 1 mgd from Rocky River Basin, back into the Catawba Basin. This pump station is
expected to be operational by January 2025 (NC DEQ Permit No. WQ0044016).

IBT MONITORING
Water supplied to CLTWater's retail customers in the Rocky River Basin, that is not returned to
the Catawba Basin, is included in the reported IBT amounts. Water provided to municipalities with
service areas in the Rocky River Basin includes the City of Concord and the Town of Harrisburg.
CLTWater can transfer treated potable water to the City of Concord through four metered
connections to their water system. All of Concord's service area is within the Rocky River Basin;
therefore, any water purchased by them becomes an IBT. Water service is only provided as an
emergency back-up to Concord's routine supply, which are Lake Howell and several smaller
reservoirs. CLTWater's agreement with Concord is that water will be supplied to them subject to
availability and subject to regulatory constraints including IBT and Federal Energy Regulatory
Commission (FERC) limitations.
Concord received an IBT Certificate in January 2007 for the transfer of up to 10 mgd from the
Catawba River Basin to the Rocky River Basin. NC DWR advised CLTWater that water sold to
Concord should not be applied to CLTWater's IBT amount. For calendar year 2022, Concord did
not purchase any water.
CLTWater can transfer treated potable water to the Town of Harrisburg through three metered
connections to their water system. Harrisburg's service area is entirely within the Rocky River
Basin, and water sales to Harrisburg are included in CLTWater's IBT amounts. For 2023
CLTWater sold on average 0.044 mgd to Harrisburg.
Table 1 summarizes actual IBT amounts for calendar years 2002 through 2023 (all amounts were
calculated using the methodology approved by NC DWR in June of 2006). The table considers the
daily amounts of water transferred from the Catawba River Basin to customers within the Rocky
River Basin that is not returned to the Catawba River Basin.
The maximum daily IBT for calendar year 2023 was 26.24 mgd in August, which was 79.5% of
the authorized IBT of 33 mgd. The average IBT for 2023 was 20.42 mgd, 61.9% of the authorized
IBT. In addition to the actual amount of IBT reported in Table 1, CLTWater has committed to
provide IBT to development that has been proposed but has not yet been activated within the Rocky
River Basin. As of December 31, 2023, 1.138 mgd was committed to Rocky River that have not
been activated; commitments are based on maximum day estimates. The combined actual plus
committed maximum day IBT for 2023 was 27.37 mgd, approximately 82.9% of the authorized
IBT.

COMPLIANCE WITH CERTIFICATE CONDITIONS
Condition 1: S. W.I.M. Program Summary
Mecklenburg County is required to annually summarize progress in implementation of watershed
management approaches of the Surface Water Improvement and Management (S.W.I.M.)
Program. Provided below is the summary of progress made during calendar year (CY)
2023. The Division of Water Resources shall have the authority to approve modifications to and
need for continued reporting as necessary.
During CY2023, watershed management approaches continued to be implemented by
Charlotte -Mecklenburg Storm Water Services (CMSWS) as part of Mecklenburg County's
S.W.I.M. Program. Efforts continued to focus on McDowell and Goose Creeks, as initiated
in 2007, as well as on the West Branch of the Rocky River in Davidson that began in
Page 4 of 6

CHARLOTTE
W6TER
2009. During calendar year 2023, the following work was completed in the three (3)
watersheds by CMSWS:
McDowell Creek (including the Torrence Creek Tributary to McDowell Creek)
1. CMSWS in partnership with the Town of Cornelius conducted on -going design on the
restoration of a portion of upper McDowell Creek West of 1-77.
Goose Creek (including the Stevens Creek Tributary to Goose Creek)
1. Ongoing monitoring and inspection of the Stevens Creek Stream Restoration project,
including evaluation of reintroduced freshwater mussels into the project area.
Rocky River
1. Design complete and construction services bid for the restoration of approximately
1.5 miles of the West Branch of the Rocky River.
Condition 2: Stakeholder Process (Completed)
A stakeholder process is required to investigate, develop, adopt, and implement storm water
ordinances that control water quantity from single-family development and water quality for all
development until completed. The requirements of Condition 2 were completed in 2007.
Condition 3: Goose Creek Subbasin (Completed)
The IBT Certificate removed the Goose Creek subbasin from the area to be served by the IBT, and
imposed a moratorium on the installation of new IBT water lines (water lines crossing the
ridgeline) into Goose Creek subbasin until the impacts of additional growth on the endangered
species were fully evaluated.
CLTWater submitted the final Environmental Assessment of new development in the Goose
Creek Basin (Mint Hill area) to the NC Division of Water Resources (DWR) in February
of 2013. The Environmental Management Commission approved the Environmental
Assessment in May of 2013 and has removed the requirements under Condition 3.
Condition 4: Environmental Management Commission
The IBT Certificate provides that the Environmental Management Commission may reopen the
Certificate under certain circumstances. This did not occur in 2023.

CHARLOTTE
W6TER
Condition 5: Compliance and Monitoring Plan
The IBT Certificate requires CLTWater to develop a compliance and monitoring plan for reporting
maximum daily transfer amounts, compliance with certificate conditions, and progress on
mitigation measures, and drought management activities. CLTWater's monitoring plan and
reporting format were approved in June of 2006 by NC DWR and continue to be used for 2023.
CLTWater operated under Stage Zero drought conditions from October 2023 through January
2024.
Charlotte Water monitored water treatment plant pump rates, streamflow and lake storage
indicators, the US Drought Monitor, and other factors in accordance with the CLTWater
Water Shortage Response Plan. Measurements were assessed monthly to ident fy
designated triggers that could indicate developing drought conditions. All appropriate
planning, communication and preparation were in place to respond as needed to changing
conditions.
In coordination with 17 other utilities in the Catawba-Wateree river basin, CLTWater
participated in regional drought response planning and response activities as directed by
the Catawba Basin Low Inflow Protocol.
SUMMARY
The actual maximum day amount of water transferred from the Catawba River Basin to the Rocky
River Basin was 26.24 mgd, which was 79.5% of the authorized maximum day value of 33 mgd.
The combined total of actual and outstanding committed IBT volumes was 27.37 mgd, which was
approximately 82.9% of the authorized maximum day value. CLTWater was in full compliance
with IBT authorizations and compliance conditions for calendar year 2023.

Executive Summary
The 2023 Annual Report on Interbasin Transfers (IBTs) for the Cities of Concord and Kannapolis
(Cities) includes monitoring data for daily tracking of IBT amounts and documentation of
compliance with all IBT Certificate conditions. Annual reports were previously prepared for
calendar years 2007 through 2021 and are available on the North Carolina Division of Water
Resources (NCDWR) website. The reports for earlier years can be found at the following website:
httvs://deq.nc.gov/concord-kannapolis.
The North Carolina Environmental Management Commission (EMC) approved the Cities' IBT
Certificate in January 2007 authorizing transfers of up to 10 million gallons per day (mgd) from
the Catawba River Basin to the Rocky River Basin and 10 mgd from the Yadkin River Basin to the
Rocky River Basin. Additionally, a grandfathered IBT of 6 mgd authorizes transfer from Second
Creek, located in the South Yadkin River Basin, to the Rocky River Basin. The terms "Cities" and
"Certificate Holders" are used interchangeably herein.
In 2023, the Certificate Holders complied with all conditions of their IBT Certificate. The Cities of
Concord and Kannapolis had a maximum daily transfer from the Catawba River Basin of 3.579
mgd during 2023. The maximum daily transfer from the Yadkin River Basin was 5.156 mgd.
In 2023, the City of Kannapolis pumped water from Second Creek to Kannapolis Lake under its
South Yadkin River Basin grandfathered IBT. The maximum daily transfer under the
grandfathered IBT from the South Yadkin River Basin to the Rocky River Basin in 2023 was -0.172
mgd. The 2023 IBT daily transfers for Concord and Kannapolis are shown in Figure ES-1.
In addition, a settlement was reached in 2010 on a lawsuit filed by the Catawba River
Foundation, Inc. and the Protect the Catawba Coalition. While this does not change the IBT
Certificate or required reporting in any way, the Cities did agree to some operational conditions
regarding the Catawba River Basin during times of drought.

2023 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS
1.0 - Introduction
The Cities of Concord and Kannapolis (Cities) received an interbasin transfer (IBT) Certificate,
which was originally approved on January 10, 2007, and signed into effect on January 25, 2007.
The North Carolina Environmental Management Commission (EMC) has authorized transfers of
up to 10 million gallons per day (mgd) from the Catawba River Basin to the Rocky River Basin
and 10 mgd from the Yadkin River Basin to the Rocky River Basin. As a condition of the IBT
Certificate, the Cities are required to produce an Annual Report that documents transfers over
the past year. Annual reports were also prepared for calendar years 2007 through 2022 and are
available on the North Carolina Division of Water Resources (NCDWR) website. The reports for
earlier years can be found at the following website: https://dea.nc.gov/concord-kannapolis.
The Cities provide water to each other, various municipalities in the area (including: Mount
Pleasant, Midland, Harrisburg, and Landis), and unincorporated areas of Cabarrus County.
Concord owns and operates the water distribution system used by the Town of Midland.
Charlotte Water and the City of Salisbury currently have contracts to provide water to the Cities
from the Catawba and Yadkin River Basins, respectively.
The terms "Cities" and "Certificate Holders" are used interchangeably herein. Figure 1-1
illustrates the ability to transfer water among the Certificate Holders and all municipalities
served by the Certificate Holders.

2.1 - Service Area Water Demand
Table 2-1 presents 2023 annual average water production for the Certificate Holders based on
finished water produced at the Hillgrove, Coddle Creek, and Kannapolis Water Treatment Plants
(WTPs). It also shows finished water purchases from Charlotte Water, the City of Salisbury and
the City of Albemarle, if they occurred. Additionally, Table 2-1 presents the 2023 annual average
IBT (or water purchases) from each basin covered by the IBT Certificate and from Second Creek,
from which transfers are authorized by a grandfathered IBT. In 2023, finished water production
averaged 13.52 mgd, purchased IBT finished water averaged 0 mgd for Catawba River Basin,
4.509 mgd for the Yadkin River Basin and -0.290 mgd for Second Creek. The combined 2023
annual average water use for the Certificate Holders was 17.73 mgd.

2.2 - Interbasin Transfers
Daily IBT amounts for the Certificate Holders are included in the Appendix. Data is provided for
the period January 1, 2023 through December 31, 2023. The maximum day IBT from the Catawba
River Basin during the calendar year 2023 was 3.579 mgd. This represents 35.79% of the
permitted maximum day, 10 mgd IBT from the Catawba River Basin under the Certificate
approved by the EMC in January 2007. The maximum day IBT from the Yadkin River Basin
during the calendar year 2023 was 5.156 mgd. This represents 51.56% of the permitted maximum
day, 10 mgd IBT from the Yadkin River Basin under the Certificate. There were transfers of water
to Second Creek with a maximum day IBT -0.286 mgd, which represents -2.867% of the permitted
maximum day, 6 mgd IBT from the South Yadkin River Basin under the grandfathered
Certificate. Table 2-2 shows the IBT use for the Certificate Holders and the percentage of use from
the Catawba and Yadkin River Basins.

3.0 - Other Related Information
In 2010, a settlement was reached in a lawsuit filed by the Catawba River Foundation, Inc. and
the Protect the Catawba Coalition. While this does not affect the IBT Certificate, its conditions, or
required reporting in any way, the Cities did agree to some operational conditions regarding the
Catawba River Basin during times of drought.
During designated droughts beyond July 1, 2015, following either Low Inflow Protocol (LIP) or
Drought Management Advisory Council (DMAC) Drought Stage declaration, the Cities have
agreed to limit the Catawba River Basin IBT so that it corresponds to water use reduction goals.
A summary of this agreement is presented in Table 3-1.

4.0 - Compliance with Certificate
Conditions
A summary of the conditions of the IBT Certificate approved on January 10, 2007 along with the
current status of compliance for each is provided below. Language from the certificate is followed
by actions for each condition.
4.1 - Condition 1 (Federal Energy Regulatory
Commission [FERC] Licensure)
If at any time any legal requirement that (a) governs the operation of the hydroelectric facilities in the
Catawba River Basin currently licensed as Federal Energy Regulatory Commission (FERC) Project No. P-
2232 or in the Yadkin Pee -Dee River Basin currently licensed as FERC Project Nos. P-2206 and P-2197
and (b) governs or affects water use and/or quality, substantially differs from the actual or anticipated
FERC license conditions or other legal requirement upon which the analysis underlying this Certificate is
based, such as changes to minimum flow requirements or drought mitigation measures, the Commission
may reopen and modify this Certificate.
This condition requires no action by the Certificate Holders.
4.2 - Condition 2 (Drought Management Plan)
Each Certificate Holder shall prepare a Drought Management Plan. The Cities shall implement measures
corresponding to the most severe level of drought conditions in either the Catawba or Yadkin River Basins.
The Cities shall not transfer any water to any other jurisdictions unless that jurisdiction agrees to be bound
by this condition in full.
The Cities submitted the Drought Management Plan on July 31, 2007; comments were received
on November 11, 2007, and the revised plan was submitted on January 8, 2008. The Drought
Management Plan was incorporated into an updated Water Shortage Response Plan (WSRP) in
2010. The WSRP, prepared as a joint document for the Certificate Holders, is available on the
NCDWR website at the following web address:
http://www.ncwater. org/W ater_Supply_Planning/W ater_Shortage_Response_Plans/plan
Table 4-1 shows Normal and Drought Stages 0-4, the names of each, the date the Catawba River
Basin managers implemented Draft LIP actions in response to drought monitoring, the Yadkin -
Pee Dee River Basin drought monitor, and the associated actions taken by the Cities.
In general, drought levels have been normal for both Catawba and Yadkin River Basins. Level 1,
Voluntary Water Restrictions, was in place from November 1 through December 31 of 2023
(Figure 4-1) for the Catawba River Basin. There were Normal levels all year for Yadkin River
Basin and majority of the year for Catawba River Basin. Other outdoor water use conservation
measures are encouraged but not required.

2023 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS
During the year, the Cities drought stages follow the drought stages of the Catawba-Wateree
Water Management Group; hence the Cities stayed in Normal Responsible Water Use Level.

4.3 - Condition 3 (Disaggregation of IBT Amount)
If the Certificate Holders discontinue their cooperative service agreement, then the permitted IBT amount
will be allocated amongst the Certificate Holders based on their projected 2030 needs.
The cooperative service agreement between the Certificate Holders remained in effect throughout
2023.
The Cities and local municipalities cooperatively and effectively communicate and manage their
respective water distribution systems. The Cities sell water to each other and reconcile billing
monthly. Additionally, Concord owns and operates the water distribution system for Midland,
providing water service to all Midland customers. Harrisburg purchases water from Concord,
measured by six meters. Concord also provides water service to unincorporated areas of
Cabarrus County. Mount Pleasant did not purchase water from the City of Concord in 2023.
Further emphasizing the interconnected nature of the Cities and local municipalities, Kannapolis
provides water to Landis, located in the South Yadkin River Basin, which is not subject to this IBT
Certificate.
4.4 - Condition 4 (Compliance and Monitoring Plan)
In cooperation with the Division of Water Resources, the Certificate Holders shall develop an IBT
Compliance and Monitoring Plan.
The Cities submitted the Compliance and Monitoring Plan on July 31, 2007. This plan was
finalized in December 2007.
4.5 - Condition 5 (EMC Consideration of Impacts)
The EMC may reopen the Certificate and adjust existing or require new conditions to ensure detrimental
impacts are mitigated if environmental impacts are found to be substantially different from those projected
in the EMC's Findings of Fact.
This condition requires no action by the Certificate Holders. The EMC did not take action on this
condition in 2023.
4.6 - Condition 6 (20-Year Certificate Evaluation)
In twenty years from the date of the Certificate, the Cities shall submit a written report to the EMC to
include: (a) summary of transfers for the previous twenty years, (b) discussion of any changes to the
environmental impacts assessment from IBT transfers, (c) summary of all actions to address actual or
potential drought conditions, (d) recommendations for any changes to the Certificate, (e) details on
consultation with interested stakeholders, and (f) certification of compliance with Certificate. This will
continue at 20-year intervals.
9

2023 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS
The IBT Certificate was approved on January 10, 2007 and signed into effect on January 25, 2007;
therefore, the first 20-year certificate evaluation report will be completed in 2027.
4.7 - Condition 7 (Limit of Certificate)
The Certificate does not exempt the Cities from compliance with any other requirements of law.
This condition requires no action by the Cities.
