DWR has been an active participant during the relicensing process and our involvement has included: scoping and refining issues to be addressed; review and/or design of technical studies; participation in field studies; participation on various technical work groups; and review and providing comments on technical studies. We have reached consensus with other resource agencies and other interests regarding the protection, mitigation, and enhancement measures needed for this project. DWR along with other DENR divisions, fellow resource agencies, APGI, and the majority of stakeholders involved in the relicensing process signed an relicensing Settlement Agreement (RSA) on March5, 2007. Components of the RSA provide an enhanced instream flow regime for the Pee Dee River downstream of Blewett Falls Dam, project modifications to meet State water quality standards for dissolved oxygen in tailwaters, improved reservoir levels, modification of the shoreline management plan, and donation or sale of important conservation lands. We recommend that the following conditions be included in the 401 certification. These recommendations are some of the Proposed License Articles in the Relicensing Settlement Agreement related to project operations, instream flows, water quality, land protection and compliance monitoring for a New FERC License for the Yadkin Project. References herein to the "License" are to the new FERC license for which DWQ is considering 401 certification, and the reference includes the new license and all annual licenses thereafter.

No later than August 31 of each year, the Licensee will report the resulting reservoir water elevations at each reservoir during the April 15 through May 15 period in a letter report to the North Carolina Wildlife Resources Commission (NCWRC). The letter report will provide an explanation of any circumstances that prevented the Licensee from maintaining the target water elevations. Within 60 days of filing the letter report with the NCWRC, a copy of the letter report will be filed with the Commission. Satisfaction of these reporting commitments shall constitute compliance with this License Article. Article PO -2 - Project Instream Flows Required Minimum Instream Flows Commencing no later than six months from the effective date of this License and except when operating under the LIP or HPMEP, the Licensee shall operate the Project so as to provide a daily average minimum flow from the Falls Development in accordance with the following schedule: June 1 — January 31 1,000 cfs February 1 — May 15 2,000 cfs May 16 — May 31 1,500 cfs Article PO -3 - Flow and Reservoir Elevation Monitoring Within six months of the effective date of this License, the Licensee shall file with the Commission a final Flow and Reservoir Elevation Monitoring and Compliance Plan for the Yadkin Project. The Flow and Reservoir Elevation Monitoring and Compliance Plan shall be developed in consultation with the North Carolina Division of Water Resources (NCDWR), the North Carolina Division of Water Quality (NCDWQ), the South Carolina Department of Natural Resources (SCDNR), the U.S. Geological Survey (USGS) and the Downstream Licensee (the Licensee of the Yadkin -Pee Dee River Project, FERC No. 2206), and shall include detailed provisions for monitoring reservoir water elevations and for monitoring flows from both the Narrows and High Rock developments. The Licensee shall include with the final plan documentation of consultation, copies of comments and recommendations on the draft plan after it has been prepared and provided to the agencies and Downstream Licensee, and specific descriptions of how comments are accommodated by the final plan. The Licensee shall allow a minimum of 30 days for the agencies and Downstream Licensee to comment prior to filing the plan with the Commission. If the Licensee does not adopt a recommendation, the filing shall include the Licensee's reasons, based on Project -specific information. The Commission reserves the right to require changes to the plan. Upon Commission approval, the Licensee shall implement the plan, including any changes required by the Commission. The Licensee shall file the final plan with the North Carolina Division of Water Quality within 30 days of receiving Commission approval. Flow monitoring through the High Rock Development powerhouse will measure flow release from the High Rock development required under License Article PO -1 or under the Low Inflow Protocol. Daily average flows within +25% of the applicable maximum flow, measured from 12:01 AM to 12:00 midnight, shall be considered compliant for each operating day. Flow monitoring in the Falls Development outflow will serve as the compliance measure for the minimum flow release from the Falls Development required under License Article PO -2 or under the Low Inflow Protocol. Daily average flows within -5% of the applicable minimum flow, measured from 12:01 AM to 12:00 midnight, shall be considered to be in compliance for any operating day so long as the applicable daily average minimum flow is achieved on a weekly average basis, measured from 12:01 a.m. Saturday to 12:00 p.m. midnight Friday. Whenever High Rock is drawn down below its NME, releases from Falls shall be limited to +/- 5% of the cfs equivalent of the Required Instream Minimum Flow at Falls, as measured on a weekly average basis from 12:01 a.m. Saturday to 12:00 p.m. midnight. The Licensee shall endeavor to meet the Required Minimum Instream Flows required in Article PO -2 and shall not intentionally utilize the flow variances provided above. The Licensee shall prepare an annual flow monitoring report documenting its compliance with minimum releases, including a record of any days during the year when the daily average required minimum instream flow fell within the -5% and was made up as part of the weekly average, a record of flows during any period when High Rock was below its NME, and a record of any LIP events. The Licensee shall file the report with the Commission and NCDENR summarizing its evaluation by no later than March 31 of the following year. Article PO -4 - Low Inflow Protocol The Licensee shall comply with the requirements of the Low Inflow Protocol shown below to the extent such requirements are enforceable by this License. Article PO -4 - Low Inflow Protocol This License Article highlights the responsibilities of the Licensee from Appendix A, "Low Inflow Protocol for the Yadkin -Pee Dee River Hydroelectric Projects" (LIP), of the Yadkin Hydroelectric Project, FERC No. 2197, Relicensing Settlement Agreement. 3.1.4.1 Definitions The following definitions shall be applicable to this Article PO -4: 1.
