It is issued to Dominion North Carolina Power ("the applicant") in Halifax County and adjacent counties pursuant to a revised application filed on the loth day of November, 2002 to, among other things, retain the Caston and Roanoke Rapids dams across the Roanoke River. The application provides adequate assurance that the retention of fill material into the waters of the Roanoke River in conjunction with -retention and operation of these dams and other project activities will not result in a violation of applicable Water Quality Standards, discharge guidelines and other applicable State laws: Therefore, the State of North Carolina certifies that this activity will not violate the applicable portions of ' Sections 301, 302, 303, 300, 307 of PL 92-500 and PL 95-217 if conducted in accordance with the application and conditions hereinafter set forth. - This approval is only valid for the purpose and design that you submitted in your application, as described in the revised application. If you change your project, you must notify us and may be required to send us a new application for a new Certification. If the property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for complying with all conditions. For this approval to be valid, you must follow the conditions listed below. The issuance of this Certification shall not exempt the applicant from complying with any and all statutes, rules, regulations, or ordinances that may be imposed by other government agencies (local, state and federal) which have jurisdiction, including but not limited to applicable river buffer rules in 15A NCAC 213 .0200, erosion and sedimentation control requirements in 15A NCAC Chapter 4 and under the Division's General Permit NCCo10000, and any requirements pertaining to wetlands under 15A NCAC 213 ,0200, 15A NCAC 2H .0500 and 15A NCAC 2H .1300. This Certification is issued on the express representation by the applicant that the Settlement Agreement referenced herein has been executed by all necessary signatories and therefore is in effect. ' If the Settlement Agreement is not in effect as of July 30, 2003 then this Certification may be modified by DWQ in order to .coincide with the relevant provisions of that Settlement Agreement. Condition(s) of Certification: Flow in the Bypass Reach 1.1 Flow of water in the bypass reach shall not be less than 325 cfs at any time except as ' modified by future adaptive management studies as approved in writing by DWQ. The adaptive management studies shall focus on the spawning window (at least March 15 through June 15)-. However, slight reduction in flows in the winter months may be approved, but shall not result in minimum flows less than 300 cfs. The flow shall be released from both the, north and south ends of the dam so that it is evenly distributed into the reach. The precise schedule for release may be developed in consultation with the Cooperative Management Team ("CMT") consisting -of representatives of the. NC Department of Environment and Natural Resources ("DENR"), NC Wildlife Resources Commission ("WRC"), US Fish and Wildlife Service ("USFWS"), National Marine Fisheries Service ("NMFS") and the applicant. 1.2 The applicant shall provide on a periodic basis for the duration of 24 consecutive hours, flow to the bypass reach of 500 cfs ("freshet flow") on a schedule provided by DWQ in consultation with W RC. The scheduling of the Soo-cfs flow may be on weekends in order. to minimize the cost of hydropower lasses. 1.3 The applicant shall follow an annual schedule provided by DWQ upon consultation with WRC to the applicant by November 30 for the following year. The annual scheduling of the 500-cfs may not exceed a total of 17 days of the freshet flows. After the annual schedule has been provided to the applicant, DWQ may modify the schedule in consultation with WRC but shall give the applicant a minimum of 10 days notice prior to modification of the 500-cfs scheduling. Whenever flood flows require opening of the Roanoke Rapids dam floodgates for at least one 24-hour period and up to 21 days, this will count as one of the Soo-cfs flow days. to 22 to 42 -day flood release would count as two freshet flow days, etc.) If, during a study cycle, the flow for a period of 21 days equals or exceeds 500 cfs, the number of freshet flows required for that year will be reduced by one. The applicant shall provide to DENR and WRC by March 31 of the following year, a report that lists the days that the 500-cfs freshet flow was passed into the bypass reach. Consistent with article FL11. section 4 of the Settlement Agreement, during cycles two, three and four of the bypass reach study, the annual scheduling of the Soo-cfs may not exceed a total of 13 days of the freshet flows. 1.4 The applicant shall reduce flood flow releases at the Roanoke Rapids dam from 35,000 cfs (or any flow greater than 5,000 cfs through the floodgates) to 25,000 cfs in consultation with the US Army Corps of Engineers ("USACE"). once the flood releases through the Roanoke Rapids floodgates are reduced to 5,000 cfs, the applicant shall reduce the flows in the bypass reach per the rates in Table 1 below: Table 1 Hour Release cfs 0 5,000 4 4,000 8 3,000 12 2;000 18 1,500 20 1,000 24 700 28 500 32 325 If flood releases occur but do not reach 5,000 cfs through the floodgates, the table above shall still be used starting at the maximum flood release. The bypass reach flow may be temporarily modified if required by unusual circumstances upon written agreement between the DWQ, and the USACE and in consultation with the Licensee and the WRC. Temporary changes will be coordinated with the other agencies of the CMT in a timely manner. 1.5 If DWQ, in consultation with the CMT, delays implementation of this condition to allow for the collection of baseline data, implementation shall begin as determined by DWQ. If the implementation of this condition is not so delayed, then the applicant shall begin releasing water into the bypass reach within one week of acceptance of the new license for Federal Energy Regulatory commission Project No. 2009 ("new FERC license"). 1.5 The applicant, in consultation with the CMT, shall conduct the study described in article FL1, section 4 of the Technical Settlement (Appendix B) of the Settlement Agreement. Consistent with such article, the applicant shall not adopt a new flow regime for the bypass reach without written approval from DWQ. 2 Minimum Releases from.the Roanoke Rapids dam -The following schedule shall be followed for the minimum release of water from the darn. "Declaration" refers to the daily mean of the USACE weekly. declaration. The applicant shall implement this new flow regime within 30 days of acceptance of the new FERC license. 3 2.1 - Minimum and Target Flow Releases from Roanoke Rapids Dam Timeframe Condition Minimum Flow Jan. 1 - 15 Declaration < 6000 cfs 2000 cfs Declaration z 6000 cfs 2500 cfs Jan. 15 - Feb. 28129 Declaration < 6000 cfs 2500 cfs or declaration, whichever is less Declaration ;.> 5000 cfs 3000 cfs March Declarations 3500 cfs minimum flow = declaration Declaration > 3500 cfs minimum flow = 3500 for peaking days 5 peaking days during month 3 peaking day limit per week 3 consecutive peaking day limit Can only peak in two of the weeks Ramp up Ramp up from min. by 5400 cfs hold for 1 hour, then go to full load Ramp down Ramp down to min. flow + 5000 cfs, hold for one hour then go to minimum flow.

Following USAGE flood control releases from the Roanoke Rapids dam, the -applicant shall work in conjunction with the USAGE to reduce flows in the mainstem river gradually during the months of May through September to minimize the effects of inflow of water with low oxygen levels into Roanoke River from downstream wetlands. Upon agreement with the USAGE and in consultation with DWQ, the applicant shall implement the following step-down schedule from a 20,000-cfs flow: Id Table 3 Hour Flow cfs 0 17,000 8 14, 000 16 12,000 20 11,000 24 10,800 28 10,000 32 9,500 36 9,000 This schedule may be revised upon written .request to DWQ if the ongoing USACE section 216 study indicates a different step-down schedule should be followed. Table 3, above, represents a maximum flow reduction schedule. A slower step-down schedule. (one that reaches the 9000 cfs flow over a longer period of time) may be approved by the USACE in consultation with DWQ and the applicant on a case by case basis. During the time -frame needed to execute the flow reduction schedule, the applicant would not engage in load -following operations. The applicant shall implement the step-down flow schedule beginning when the applicant has accepted the new FERC license. 3 Downstream Water Quality ae 3.1 Minimum Flow - Minimum flows.to address downstream uses _are discussed in Condition 2 of this certification. 3.2 Erosion and Sedimentation -- The applicant shall develop a plan to monitor the effect of within -day peaking on benthic mac roi nve rteb rates, fish communities and stream bank erosion along the 13 g Roanoke River downstream of the Roanoke Rapids dam. The development of that plan shall be in cooperation with a CMT consisting of WRC, DENR, USFWS, NMFS, the Nature Conservancy ("TINIC"), and the applicant, with the Regional Partnership of Local Governments ("RPLG") as an ex officio member. Monitoring cycles shall consist of five-year periods beginning when the applicant accepts a new FERC license. The applicant shall be required to fund the cost of implementing the monitoring plan. up to the amount of $30,000 annually (2002 dollars adjusted according 'to the Consumer Price Index). Any portion of the $30,000 not utilized shall be carried forward to the Licensee's future annual budget cycles and shall be in addition to the $30,000 allocated for that cycle. In the thirtieth year of the license, the Licensee shall consult with the CMT to determine if an increase in funding of the monitoring program is appropriate. Within one year of the acceptance of the new FERC license, the applicant shall transmit the plan to DWQ for written approval and subsequent implementation by the applicant. If DWQ does not provide written comments to the applicant within 60 days of receipt of this plan, then the plan may be implemented as submitted. . During the first monitoring cycle, data collection shall not be required to start until year two to allow for development of the monitoring plan and protocols. DWQ, in consultation with the CMT, will review monitoring data at the end of each cycle to determine if it establishes a link between the applicant's within -day peaking and (a) erosion of the banks of the Roanoke River downstream of the Roanoke Rapids dam and/or (b) negative effects on downstream benthic macroinvertebrate or fish species and communities. If such a link is established, then DWQ — in consultation with the CMT -- will develop an approach that requires the applicant to address those effects by modifying one of the following: maximum peaking flow; difference between base flow and peak flow on peaking days; ramping rates; duration of base flow. (in hours) between peaking releases; modification of the definition of a .peaking period in condition 8 of this Certification; or some other modification that the CMT suggests might reduce adverse impacts of within -day peaking on aquatic biota and/or stream bank stability. Seasonal variations 5 may also be incorporated in this approach. Upon written notification of the development and written approval from DWQ for this approach, the applicant shall implement this approach. If subsequent monitoring indicates a continuing link between within -day peaking operations and bank erosion and/or negative effects on downstream aquatic species and communities, then DWQ — in consultation with the CMT — will develop an additional incremental modification from the those listed in the paragraph above that the applicant must implement to further reduce those effects. Upon written notification of any additional incremental modification, and so long as such modifications reduce the latitude available to the applicant for within -day peaking by a proportional amount equivalent to 5 divided by the period of the new FERC license in years, the applicant shall implement such modification. The exact means for calculating the proportionality of steps will be determined by DWO in consultation with the CMT. If any operational changes subject to this section (3.2) would conflict with release requirements subject to sections 2, 3.4 or 3.5 of this Certification, then the flow-related conditions of these other sections shall take precedence. 3.3 Minimum Oxvgen Releases from the Roanoke Rapids Dam -Water flowing through the hydropower "turbines from the Roanoke Rapids dam shall meet or exceed the instantaneous dissolved oxygen standard in effect as of the date of the discharge. The instantaneous dissolved oxygen standard as of the date of this Certification is 4.0 mg/L (ppm) (15A NCAC 2B .0211(3)(b)). Water flowing through the hydropower turbines from the Roanoke Rapids dam shall meet or exceed the mean, daily dissolved oxygen standard in effect as of the date of the discharge. The mean, daily dissolved oxygen standard as of the date of this Certification is 5.0 mg/L (ppm) (15A NCAC 28 .0211(3)(b)). The daily mean oxygen concentration shall be calculated as the mean of all instantaneous analyses collected in a 24-hour period to be no less than 24, hourly measurements. If dissolved oxygen concentrations immediately upstream of the project do not meet or exceed the instantaneous dissolved oxygen standard and mean, daily dissolved oxygen standards in effect as of the date of the discharge, then the Raleigh Regional office of DWQ shall be notified in writing and via telephone. In any case, the dissolved oxygen in the water flowing through the hydropower turbines from the Roanoke Rapids dam shall equal or exceed the upstream dissolved oxygen concentration. Oxygen concentrations shall be measured in the tailrace. Within six months of the applicant's acceptance of a new FERC License, the applicant shall submit a draft agreement to DWQ regarding the location of the sampling point upstream of the project. If the dissolved oxygen water quality standard is not met in the tailwaters below Roanoke Rapids dam, then the applicant shall begin sampling for dissolved oxygen levels within two business days in Lake Gaston and in the tailwaters below Lake Gaston. Data from the Roanoke Rapids monitoring shall be maintained on a real-time basis via internet and forwarded to the Wetland/401 Unit, the Ecosystems Unit and the Raleigh and Washington Regional Offices of DWQ every other month from November 1 through May 31 and monthly from June 1 through October 31. Data must be submitted electronically and DWQ shall be notified in writing that the data have been sent. Data must include Flow (cfs), Dissolved Oxygen concentrations (mg/L) and Water Temperature (°C). In the event of temporary emergency conditions arising in the performance of the above conditions, the applicant shall cooperate in good faith with DWQ and WRC to take such reasonable steps to protect the water quality of the Roanoke River below the Gaston and Roanoke Rapids darns. 3.4 Flow Au mentation from Lake Gaston Storage durina Drought Conditions - Conditions requiring flow augmentation from Gaston storage: If all four of the following conditions are met, the applicant shall begin augmenting downstream flows from the Lake Gaston storage in consultation with DWQ and WRC. R a) USAGE is operating Kerr reservoir under its drought management strategy, b) Roanoke Rapids dam is not in a hydropower peaking mode and is only releasing drought minimum flows as directed by the USAGE drought management strategy or when condition 2.2 is in effect, c) A weekly declaration from USAGE is issued that is less than the total of drought minimum flow - required at the Roanoke Rapids dam, and d) Lake Gaston water level is above 197' msl. Lake Gaston stora e - Lake Gaston normal water level shall be regulated by the applicant in order to maintain the existing uses of the lake with the following provisions. If all of the drought storage is used for downstream flow augmentation, then the applicant shall regulate Lake Gaston from 197.5' msl to 196.5' msl, in order to meet system operational needs with the following provisions: a) For the purpose of flow augmentation downstream under the conditions listed above, Lake Gaston has 3 feet of drought storage. - b) Lake Gaston has approximately 60,000 acre-feet of storage between 200' msl and 197' msl. c) The applicant utilizes one foot of storage for normal operation between 200' msl and 199' msl. Once above conditions are met, Lake Gaston storage shall be used to augment the downstream flow to adhere to the FERC minimum flow, per direction of DWQ. Once Lake Gaston reaches 197' msl, flow augmentation shall cease and flow entering the project from Kerr Lake shall equal the flow leaving the Roanoke Rapids dam, after accounting for consumptive withdrawals, evaporation and inflows to Lake Gaston and Roanoke Rapids Lake. When the USAGE weekly declaration begins to exceed the Roanoke Rapids dam drought minimum flows, the applicant shall allow Lake Gaston to refill to 199.5' msl prior to: a) exceeding drought minimum flow at the Roanoke Rapids dam and, b) starting to operate the Roanoke Rapids project in a hydropower peaking mode. The applicant shall implement these conditions only upon consultation ►with and direction from the USAGE and DWQ. 3.5 Downstream Water Qualitv Monitorin - The applicant shall fund three of the current USGS continuous water quality .monitoring stations for dissolved oxygen and temperature at Halifax, Oak City and Jamesville: These stations shall be. operated continuously throughout the year. The applicant shall provide funding annually by March 1 st of each year to DEN R. The stations shall be monitored to document that dissolved oxygen levels in the Roanoke River, as a result of the drainage of water from the. floodplain resulting from project, operations, equals or exceeds the instantaneous dissolved oxygen standard and mean, daily dissolved oxygen standards in effect as of the date of the discharge in the mainstem river (15A NCAC 2B .0211(3)(b)). This concentration shall be calculated using all available daily data or as (at least) the mean of 24, hourly instantaneous analyses. At such time DWQ establishes that the applicant's operations do not or no longer affect downstream water quality, applicant funding shall no longer be required. If funding is discontinued in accordance with this Condition and subsequent applicant operational changes enable DWQ to demonstrate that water quality monitoring is again necessary, the applicant's funding requirement shall be reinstated. The study period shall be mutually agreed upon by the applicant, DWQ and WRC. 7 Data shall be forwarded to the Wetlandl401 Unit, the Ecosystems Unit and the Raleigh and Washington Regional offices of DWQ every other month (bi-rn onthly) from November 1 through May 31 and monthly fromJune 1 through October 31. Data must be submitted- electronically. Data must include all available parameters collected by the USCS (e.g. stage or flow) in addition to: site, date, time, depth, dissolved oxygen concentrations (mg/L), and water temperature (oC). In the event of -emergency water quality conditions, the applicant shall cooperate in good faith with DWQ and WRC to take such reasonable steps to protect the water quality of the Roanoke River below the Roanoke Rapids dam. The applicant, DWQ and WRC shall mutually agree upon a method of evaluating data collected within the first year of monitoring. Data evaluation shall occur on a five-year cycle. If during water quality data evaluation, DWQ tin consultation with WRC) finds that scientific data establish a causal link between the applicant's rescheduling of the USACE's weekly declaration and the reduction of water quality in the mainstem river below State standards, the applicant with concurrence of DWQ and WRC shall. identify and implement operational changes that will significantly reduce the applicant's water quality impacts. Each operational change implemented according to the preceding paragraph must reduce the applicant's rescheduling of the USACE weekly declaration by a proportional amount equivalent to 5 divided by the period of the new FERC. license in years. Thus, if as the result of monitoring, the applicant implements a change to reduce its rescheduling of the USACE weekly declaration at the end of each monitoring .cycle, by the end of the last monitoring cycle, each day the applicant shall release one seventh of the USACE weekly declaration. The exact .means for calculating the proportionality of steps will be determined by DWQ in consultation with WRC and the applicant. The applicant's flexibility for scheduling releases during a peaking day is not constrained by this condition. The applicant is not required by this Certification to make modifications to the, USACE weekly_ declaration. The maximum operational duty of the applicant under this. condition is reached when the daily water flow through the Roanoke Rapids dam equals one-seventh of the USACE weekly declaration as long as this flow does not conflict with the requirements of condition 3.4 above. 4 Reporting of Consumptive Uses The applicant shall identify and report in writing existing and proposed consumptive uses to DWQ. and the NC Division of Water Resources ("DWR"). The applicant shall report the existing or projected (as appropriate) average consumptive withdrawal and maximum capacity for each withdrawal. The applicant shall report existing consumptive uses to DWQ and DW R within 60 days of the acceptance of the new FERC license and shall report proposed new or expanded consumptive uses to DWQ and DWR within 30 days of receiving a request for the proposed new or expanded withdrawal and before submitting any requests to FERC. Conditions 4 through 7 of this Certification apply to large consumptive uses, but not exclusively. 5 Conservation and Drought Management In anticipation of low flow conditions, such as occur during critical droughts, the applicant shall take actions as described in this Certification to ensure that sufficient water of adequate quality is and will be available to assure compliance with State water quality standards and.other appropriate requirements of State law. In furtherance of the purposes of this condition, article FL6, section 3 of the Technical Settlement (Appendix B) of the Settlement Agreement ("FL6 § 3"), is made part of this Certification as if set forth fully herein. Any amendment to FL6 § 3 shall not become a part of this Certification except through the procedures set forth in condition 7. The applicant shall take all actions specifically required of the applicant by FL6 § 3 and shall take all other necessary actions within its authority to implement FL6 § 3. P 8 No Fights Granted This Certification does not grant or affirm any property right, license or privilege in any waters or any right of use in any waters. This Certification does not authorize any person to interfere with the riparian rights, littoral rights or water use rights of any other person, and this Certification does not create any prescriptive right or any right of priority regarding any usage of water. No person shall interpose this Certification as a defense in any action respecting the determination of riparian or littoral rights or other water use rights. No consumptive user is deemed by virtue of this Certification to possess any prescriptive or other right of priority with respect to any other consumptive user regardless of the quantity of the withdrawal or the date on which the withdrawal was initiated or expanded. This Certification issues on the express understanding of DEN R that, pursuant to Federal Power Act section 27,16 U.S.C. § 821, the new FERC license does not establish or determine a proprietary right to any use of water. It establishes the nature of the use to which a proprietary right may be put under the Federal Power Act. 7 Continuing Compliance - The applicant shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with section 303(d) of the Clean Water Act, 33 U.S.C. § 1313(d)) and any other appropriate requirements of State law and federal law. if DwQ determines that such standards or laws are not being met (including- the failure. to sustain a designated or achieved use or to comply with -any new or amended water quality standards or other appropriate requirements of State or federal law) or that State or federal law is being violated, or that further conditions are necessary to assure .compliance, DwQ may reevaluate and modify this Certification to include conditions appropriate to assure compliance with such standards and requirements in accordance with 15A NCAC 2H.0507(d). Before modifying the Certification, D1NQ will notify the applicant and FERC, provide public notice in accordance with 15A NCAC 2H.0503 and provide opportunity for public hearing in accordance with 15A NCAC 2H.0504. Any- new or revised conditions will be provided to the applicant in writing, will be provided to the USAGE for reference in any permit issued pursuant to Section 404 of the Clean Water Act, 33 U.S.C. § 13449 for the project, and shall also become conditions of the new FERC license for the project. This condition shall constitute "reserved authority" as that term is used in Section 9.2 of the Settlement Agreement.
