Information for this report is based on multiple site visits conducted by staff of this office with representatives from Duke Energy and HDR, and a review of the PN issued by the Corps. The report is submitted in accordance with the provisions of the National Environmental Policy Act; Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e); and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). According to the information presented, the proposed project consists of modifying the existing Cedar Cliff dam auxiliary spillway and main dam berm to safely pass the calculated Probable Maximum Flood (PMF), which is defined as the Inflow Design Flood (IDF), without overtopping the Cedar Cliff dam. The PMF peak inflow of the Cedar Cliff project is about 192,000 cfs, which was approved by FERC on June 22, 1994. Based on this and engineering calculations, the auxiliary spillway is incapable of passing the PMF and needs to be increased by about 112,000 cfs to prevent overtopping the dam. The FERC identified the IDF as the PMF in correspondence to Duke Energy dated April 24, 2014, and requested that the project be modified to safely pass all flows up to and including the IDF. To meet this objective, Duke Energy is proposing to completely demolish the two existing fuse plug chambers and single concrete splitter wall within the existing auxiliary spillway. The existing auxiliary spillway channel will be widened by about 50 feet. To complete the widening of the existing spillway, the existing rock wall along the spillway must be excavated and about 316,000 cubic yards of material will need to be removed. Duke Energy is proposing to dispose of about 25,000 cubic yards of excavated rock material by placing it on the downstream face of the rock fill dam. The remaining excavated material will be loaded onto barges and deposited into the Cedar Cliff impoundment. Upon completion of the excavation, an 11 -feet high concrete parapet wall will be constructed along the crest of the dam and six cast -in-place Hydroplus Fusegates will be constructed in the control section of the spillway. Temporary impacts associated with the project consist of constructing a culvert crossing of the East Fork bypass reach immediately downstream of the Cedar Cliff dam. Three corrugated metal pipes (110 -feet long by 12 -feet in diameter) will be placed in the East Fork bypass reach for this crossing. The culverts will be removed when construction is completed. Endangered Species. On March 23, 2016, Mr. Bryan "Tompkins and Ms. Susan Cameron of this office met with representatives from Duke Energy and HDR, Inc. at the project site to determine if suitable habitat existed within the project area for Northern Long -Eared Bat (Myotis septentrionalis) and/or Indiana Bat (Myotis sodalis). Northern Long -Eared Bat is currently federally listed as a threatened species; and Indiana Bat is currently federally listed as an endangered species. No known hibernacula for these species occurs within '/4 mile of the project area and no known maternity roosts occur within 150 -feet of the project area. However, suitable maternity roosting habitat was found to occur along the bluff adjacent to the auxiliary spillway. For this reason, Mr. Tompkins and Ms. Cameron made recommendations to Duke Energy for summer acoustic surveys to be conducted, within the 3 -acre blasting and clearing area of the project, to determine presence/absence of these species. A survey plan was established and approved by this office and surveys were conducted at two sites within the project area from May 16 — May 18, 2016. The final report of the findings from the survey was submitted to this office on June 13, 2016. According to the report, five hndiana Bat and eight Northern Long -Eared Bat call files were identified. Upon review, Mr. Tompkins informed Mr. Mulalskl that the survey results indicated that both species (Indiana Bat and Northern Long - Eared Bat) were present within the project area. Because the survey results indicated potential presence, Duke Energy has proposed the following measures to be implemented into the project plans to avoid impacts to Indiana Bat and Northern Long -Eared Bat: 1. Trees within the 3 -acre blasting and clearing area will be cut during the winter (October 15 - April 15) to avoid impacts to avoid the maternity roost period for Indiana Bat and Northern Long - Eared Bat. 2. If any random trees must be cut during the summer roost period, this office will be notified and an experienced biologist will conduct an on-site habitat assessment to determine if trees are suitable maternity roost trees. If the tree(s) to be cut are suitable roost trees, an emergence survey will be conducted before tree removal. 3. A1l potential suitable roost trees identified adjacent to the project area will be marked and protected during clearing activities. We appreciate the proposal to implement the conservation measures to avoid impacts to Indiana Bat and Northern Long -Eared Bat. However, we believe an additional measure is necessary if emergence surveys are conducted before the removal of random tree(s) during the summer maternity roost period. If emergence surveys are conducted, and bats are observed using the tree(s) to be removed, we recommend that this office be contacted to establish a plan for proceeding before the tree(s) is removed. If the above stated measures are implemented into the project plans (including our additional recommendation), we could concur with a "may affect, not likely to adversely affect" determination for Indiana Bat and Northern Long -Eared Bat; and the consultation requirements under section 7 of the Act have been fulfilled. For all other federally listed species known to occur in Jackson County, we concur with the "no effect" determination issued by Duke Energy and HDR, Inc. Therefore, we believe the requirements under section 7 of the Act are fulfilled. However, obligations under section 7 of the Act must be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. Erosion Control. The PN included a statement that erosion control would be addressed as established in the Shoreline Management Plan for the project. We are not aware of any specific information in the Shoreline Management Plan concerning erosion control measures for a reservoir drawdown of the magnitude necessary for the proposed project. We recommend that Duke Energy develop a plan to monitor and mitigate for erosion along the exposed reservoir banks. After rain events, areas near storm water outfall pipes or culverts that release high velocity discharges onto exposed banks should be inspected for erosive reels or mass wasting. The plan should include measures that will be implemented should erosive/mass wasting areas be found that are contributing sediment to the river channel. We recommend the use of straw bales or other devices at problem sites to decrease velocity of water, decrease erosion, and minimize the amount of sediment released. Any problem areas should be documented. Information on documented problem areas should be maintained to focus efforts on erosion control during any future drawdowns. Reservoir Drawdown. The PN indicated that the water level in the reservoir will be drawn down about 30 feet for a duration of 14 to 16 months to facilitate construction of the spillway modifications. The PN did not include a drawdown schedule for the project. To ensure that aquatic resources within the reservoir are not adversely affected by the drawdown of the reservoir, we recommend that Duke Energy consult and reach agreement with the USFWS, other natural resource agencies, and regulatory agencies concerning any reasonable and necessary measures to minimize the impacts of the drawdown. We appreciate the opportunity to provide these comments.

We have reviewed the materials submitted and offer the following comments. Based on our knowledge of the area, it is unlikely that any archaeological resources that may be eligible for inclusion in the National Register of Historic Places will be adversely affected by the project. The East Fork Hydroelectric Project is eligible for listing in the National Register of Historic Places (NRHP) under Criterion A for `Engineering." However, when the East Fork Hydroelectric Project was evaluated in 2014, the Cedar Cliff Development (JK0729), was determined to be a non-contributing element of the historic property. Therefore, proposed improvements to the Cedar Cliff Development dam will not diminish the integrity for which the East Fork Hydroelectric Project is considered to be historic. Before improvements to the dam at Cedar Cliff are initiated, we request photographs thoroughly documenting the current condition of the dam and its surroundings. Please refer to our guidelines for labeling and submitting digital images at http://www.hpo.ncdcr.gov/digitaVNCHPO Digital Photo Policy.html. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.
