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. 1 Figure 1: Statutorily designated IBT river basins Designated Interbasin Transfer River Basins As defined in G.S. §143-2t5.22G SS 13.1 BASIN NAME 1-1 Broad River 2-1 Haw River 2-2 Deep River 2-3 Cape Fear River 2-4 South River 2-5 Northeast Cape Fear River 2-6 New River 3-1 Catawba River 3-2 South Fork Catawba River 4-1 Chowan River 4-2 Meherrin River 5-1 5-2 5-3 Nolichucky River French Broad River Pigeon River 6-1 Hiwassee River BASIN NAME 7-1 Little Tennessee River 7-2 Tuskasegee River 8-1 Savannah River 9-1 Lumber River 9-2 Big Shoe Heel Creek 9-3 Waccamaw River 9-4 Shallotte River 10-1 10-2 10-3 Meuse River Contentnea Creek Trent River 11-1 New River 12-1 Albemarle Sound 13-1 Ocoee River 14-1 Roanoke River BASIN NAME 15-1 Tar River 15-2 Fishing Creek 15-3 Pamlico River & Sound 16-1 Watauga River 17-1 White Oak River 18-1 Yadkin River 18-2 South Yadkin River 18-3 Uwharrie River 18-4 Rocky River 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 2023, 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. 2 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 2022 IBT Annual Report.

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. According to the 2022 Charlotte Water IBT Annual Report, based on billing data, Charlotte Water experienced a single, max day transfer event of 28.32 mgd in June 2022. This represents approximately 85.8% of the total allowable transfer (33 mgd). This is suspected to have been caused by unusually high temperatures and drought -like conditions. To help mitigate this situation, Charlotte Water constructed a pump station to move 1 mgd of treated wastewater from the Rocky River basin back to the Catawba River basin. Following this event, the max day transfer demands have remained below 80%. Nonetheless, following this event Charlotte Water began working in earnest to establish a plan for requesting a modification to their existing IBT Certificate. 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 2022 are presented below in Table 1. Charlotte Water's 2022 IBT annual report is included in Appendix B. Annual reports from 2002-2022 are available on the division's website at, Charlotte Water IBT Page. 4 Table 1: Charlotte Water 2022 Interbasin Transfers Calendar Year 2022 Avg. Annual IBT (MGD) Max. Day IBT (MGD) 20.39 (61.8%) 28.32 (85.8%) Values in parentheses represent the percentage of the total allowable transfer per the IBT Certificate. 5 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' 2022 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 6 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 2022 are summarized below in Table 2.

No value listed is effectively zero. In 2022, the maximum day IBT from the Catawba River Basin was 3.50 MGD, which represents 35.0 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 2022 was 5.23 MGD, which represents 52.3 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 0.479 MGD, which represents 4.79 percent of the permitted maximum day transfer of 10 MGD. The average day IBT from the Yadkin River Basin was 3.42 MGD, which represents 34.2 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 -0.10 MGD, which represents -1.67 percent of the allowable maximum day transfer of 6 MGD from the South Yadkin River Basin under the grandfathered transfer. The 2022 annual report is included in Appendix C. Annual reports from 2007-2022 are available on the division's website at, Concord & Kannapolis IBT Page. 7 CONCLUSION Based on the information previously discussed in this report, the Division of Water Resources estimates that IBT certificate holders transferred approximately 20.76 MGD, on an average daily basis, from the Catawba River basin in 2022. On a maximum day basis, approximately 29.07 MGD was transferred from the Catawba River basin in 2022. 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. 8 Appendix A: North Carolina General Statute §143-215.22L 9 § 143-215.22L.

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.

Division of Water Resources 1611 Mail Service Center Raleigh, North Carolina 27699-1611 Subject: IBT Report for 2022 Dear Mr. Brady: We are sending our calendar year 2022 IBT Annual Report. We are also transmitting this report to you electronically. The report follows the format of earlier reports and includes a narrative section with background and program progress reports along with spreadsheets detailing the IBT amount calculation. For calendar year 2022 we experienced an actual maximum day IBT based in June billing data of 28.32 mgd. Of our authorized 33 mgd IBT, this value was approximately 85.8%. The average IBT was 20.28 mgd, approximately 61.4% of authorized IBT. We suspect the reason of this large increase in max day IBT was due to unusual high temperatures and drought like conditions seen in June. The Catawba-Wateree River Basin Low Inflow Protocol (LIP) reached Stage 0 (Low Inflow Watch Stage) based on the streamflow and US Drought Monitor triggers, and the Watch Stage was active between January 2022 and January 2023. In an effort to reduce future IBT, CLTWater is currently constructing a pump station that will be capable of pumping 1MGD (initially) from the Rocky River basin back into the Catawba (Permit No. WQ0044016). As of December 31, 2022, there were additional outstanding IBT commitments of 2.77 mgd. This total takes into account permitted donated projects (largely subdivisions) and non -activated master metered connections. We are aware of the impact of these additional flows on our current IBT. Please let me know if you have any questions. Sincerely, Bhavana Swayampakala, PE Division Manager - Planning Charlotte Water 5100 Brookshire Blvd, Charlotte, NC 28216 charlottewater.org t ? Operated by the City of Charlotte CHARLOTTE W6TER Charlotte Water Annual Report on Interbasin Transfer Calendar Year 2022 INTRODUCTION The North Carolina Environmental Management Commission (EMC) approved Charlotte Water's (CLTWater's) petition to increase the amount of water transferred from the Catawba River basin to the Rocky River basin. An interbasin transfer (IBT) Certificate was issued on March 14, 2002, that authorizes 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). The Catawba-Wateree River Basin Low Inflow Protocol (LIP) reached Stage 0 (Low Inflow Watch Stage) based on the streamflow and US Drought Monitor triggers, and the Watch Stage was active between January 2022 and January 2023. Due to continued drought conditions in June of 2022, CLTWater saw an unusual increase in demand that resulted in exceeding the 80% max day IBT. 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 Blue Granite — Lake Wylie (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. Page 2 of 6 CHARLOTTE W6TER CLTWater is currently constructing a lift station that will be capable of pumping 1 MGD ADF from Rocky River Basin, back into the Catawba Basin. This pump station is expected to be complete in second quarter of 2024 (Permit No. WQ0044016). This pump station can be upsized to a 2.5MGD station in future. This will help to further reduce the IBT amounts. 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 three 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. All of these reservoirs are within the Rocky River basin. Wastewater from Concord is treated at the RRRWWTP. 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 is included in CLTWater's IBT amounts. Table 1 summarizes actual IBT amounts for calendar years 2002 through 2022 (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 2022 was 28.32 mgd in June, which was 85.8% of the authorized IBT of 33 mgd. The average IBT for 2022 was 20.39 mgd, 61.8% 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, 2022, 2.77 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 2022 was 31.09 mgd, approximately 94.2% of the authorized IBT. Page 3 of 6 CHARLOTTE W6TER Table 1: Actual IBT Summary Calendar Year Avg.

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) 2021. The Division of Water Resources shall have the authority to approve modifications to and need for continued reporting as necessary. During CY2021, 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 2009. During calendar year 2021, the following work was completed in the three (3) watersheds by CMSWS: Page 4 of 6 CHARLOTTE W6TER McDowell Creek (including the Torrence Creek Tributary to McDowell Creek) 1. CMSWS in partnership with the Town of Cornelius completed the Willow Pond Project. The project restored a free flowing stream in place of an ornamental pond and restored additional reaches of upper McDowell Creek. 2. CMSWS in partnership with the Town of Huntersville has completed construction of a stream restoration project downstream of North Mecklenburg Park through the Hamptons Neighborhood to Statesville Road. 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. Construction was completed on Phase I of the restoration of a tributary of the South Prong of the West Branch of the Rocky River. The remaining two (2) phases of the project, which are on the South Prong of the Rocky River, will be constructed as funding and stakeholder input allows. 2. Easement acquisition was underway for the restoration of approximately 1.5 miles of a tributary of the South Prong West Branch of the Rocky River. The project is awaiting allocation of funding prior to hiring a design consultant 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. Page 5 of 6 CHARLOTTE W6TER 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 2022. 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 2022. 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 28.32 mgd, which was 85.8% of the authorized maximum day value of 33 mgd. The combined total of actual and outstanding committed IBT volumes was 31.09 mgd, which was approximately 94.2% of the authorized maximum day value. CLTWater was in full compliance with IBT authorizations and compliance conditions for calendar year 2022. The increase in consumption this year was due to the region being in a Low Inflow Watch Stage (Stage 0) during all of 2022 that culminated in June 2022 with low to no rainfall and high local temperatures in the month of June.

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 2022, 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 0 mgd during 2022. The maximum daily transfer from the Yadkin River Basin was 6.790 mgd. In 2022, 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 2022 was -0.032 mgd. The 2022 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. 2022 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS Table ES-1 2022 IBT Average Annual & Maximum Day Demands for Concord and Kannapolis Service Areas Second Creek Catawba River Basin.

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 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: 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. 1 2022 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS Figure 1-1 Water Connections of the Certificate Holders and All Municipalities Served by the Certificate Holders South Yadkin River Basin Landis Catawba River Basin Charlotte Water CDTownship/Utility Rocky River Basin Concord Yadkin River Basin Raw Water - Finished Water - ► Water Sales 2 2022 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS 2.0 - IBT Monitoring 2.1 - Service Area Water Demand Table 2-1 presents 2022 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 2022 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 2022, 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 2022 annual average water use for the Certificate Holders was 17.73 mgd.

Data is provided for the period January 1, 2022 through December 31, 2022. The maximum day IBT from the Catawba River Basin during the calendar year 2022 was 0 mgd. This represents 0% 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 2022 was 6.79 mgd. This represents 67.9% 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 -0.032 mgd, which represents -0.533% 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 2022 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS Table 2-2 2022 IBT Average Annual & Maximum Day Demands for Concord and Kannapolis Service Areas Catawba River Basine Water Purchase Year (mgd) Average Max.

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. Table 3-1 Catawba River Basin IBT during Drought Conditions LIP Stage or DMAC Drought Stage Maximum Day Transfer (mgd) 0 / Abnormally Dry 10.0 1 / Moderate Drought 9.0 2 / Severe Drought 8.5 3 / Extreme Drought 7.0 4 / Exceptional Drought 6.0 5 2022 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS 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. Level 0, Normal Responsible Water Use, was in place from January 1 through December 31 of 2022 (Figure 4-1). Other outdoor water use conservation measures are encouraged but not required. 6 2022 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. Normal Responsible Water Use Level 0 voluntary Water Restrictions Level 1 Mandatory Water Restrictions Level 2 Enhanced Mandatory Level 3 Emergency Mandatory Level 41 The Cities have agreements in place that include enforcement policies with other systems that purchase water from them. 7 Table 4-1 Concord and Kannapolis 2022 Normal and Drought Stages Drought Stage 0 Drought Monitor Classification 2022 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS 2022 Period of Drought Catawba River Basina Yadkin River Basin" (NC Drought Monitor) (NC Drought Monitor) Normal January 1— December 31 Abnormally Dry 1 Moderate Drought 2 Severe Drought 3 Extreme Drought 4 Exceptional Drought January 1— December 31 Action by Cities Cities' Actions Taken a The Catawba River Basin is listed as the drought stage declared by the Catawba-Wateree Drought Management Advisory Group. b The Yadkin River Basin is listed as the drought stage declared by the Yadkin -Pee Dee Drought Management Advisory Group 8 2022 ANNUAL REPORT ON INTERBASIN TRANSFERS FOR THE CITIES OF CONCORD AND KANNAPOLIS 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 2022. 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 2022. 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 2022. 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 2022 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. 10 APPENDIX Daily Interbasin Transfer Amounts for 2022 2022 Concord-Kannapolis IBT Tracking Condition of IBT Certificate (January 25, 2007) Maximum day transfer from the Catawba River Basin Maximum day transfer from the Yadkin Pee -Dee River Basin Maximum day transfer from the South Yadkin River Basin (grandfather) 10 10 6 Maximum day transfer to the South Yadkin River Basin (cannot exceed transfer from South Yadkin by more than 1.99 MGD) Map Code Source Basin DATE 1/1/2022 1/2/2022 1/3/2022 1/4/2022 1/5/2022 1/6/2022 1/7/2022 1/8/2022 1/9/2022 1/10/2022 1 /11 /2022 1/12/2022 1/13/2022 1/14/2022 1/15/2022 1/16/2022 1/17/2022 1/18/2022 1/19/2022 1/20/2022 1 /21 /2022 1/22/2022 1/23/2022 1/24/2022 1/25/2022 1/26/2022 1/27/2022 1/28/2022 1/29/2022 1/30/2022 1 /31 /2022 2/1/2022 2/2/2022 2/3/2022 2/4/2022 2/5/2022 2/6/2022 2/7/2022 2/8/2022 2/9/2022 2/10/2022 2/11/2022 2/12/2022 2/13/2022 2/14/2022 2/15/2022 2/16/2022 2/17/2022 Water Transfer (MGD) to Rocky River Basin Salisbury 1 South Yadkin Yadkin Raw Water to Kannapolis Lake from Second Creek 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 Salisbury Finished water Interconnection with Kannapolis Albemarle 1 Charlotte 1-3 Yadkin Catawba Albemarle Finished water Interconnection with Concord Charlotte Water Finished water Interconnections with Concord 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 I 3.723 L �1 3.591 3.699 4.012 4.341 4.330 3.996 3.980 4.204 4.274 3.990 4.161 3.951 3.870 3.790 3.802 3.806 4.104 4.080 3.895 4.305 3.922 4.049 4.363 4.590 4.626 4.552 4.531 4.454 4.127 4.584 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 4.920 4.847 4.730 4.701 4.759 4.571 4.665 4.511 4.156 4.413 4.633 4.451 4.472 4.482 4.483 4.516 4.521 I 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 Water Sales (MGD) South Yadkin Kannapolis Finished water sales to Landis 0.256 0.232 0.241 0.259 0.269 0.266 0.258 0.250 0.244 0.299 0.270 0.274 0.27 0.266 0.275 0.256 0.271 0.271 0.275 0.285 0.299 0.270 0.312 0.310 0.356 0.332 0.276 0.267 0.320 0.275 0.278 0.320 MGD MGD MGD IBT Totals Per Basin NOTE: All Wastewater discharge is to the Rocky River from RRWWTP, excluding water sales to Landis (subtracted from Total South Yadkin IBT).
