W-Q V-t S IvIr rv1o? l? i ?J 3 t t 5/18/2006 U.S. Environmental Protection Agency Comments on APGI Agreement in Principle (dated May 5, 2006) A) Proiect Reservoir Operations - Reservoir Operating Guides, High Rock Proposal: APGI proposes to pass through the guide curve as needed to maintain downstream minimum flows or as provided under the LIP or HPMEP. Whenever the reservoir water levels falls below the guide, APGI will reduce its generation at High Rock to the daily average flow equivalent of the minimum flow requirement at Falls plus up to 25%. Comments: Reservoir levels should be established as compliance minimums. The only excursion below these levels should come as a result of initiation of the LIP or HPMEP situations. Does the OASIS modeling show instances where it is necessary to drawdown lake levels to meet minimum flows in situations other than an LIP or HPMEP? Unless this is demonstrated, EPA does not support this proposal. If APGI needs a "buffer" to allow for operational flexibility, EPA recommends that APGI establish "target" lake levels higher than 4/10 for High Rock Lake, with the ability to draw down to 4/10, as necessary to meet downstream flows. B) Proiect Instream Flows - Minimum Flow Proposal: APGI proposes to file the Flow Monitoring Plan within 24 months of the effective date of the new license. Comments: EPA recommends filing of the Flow Monitoring Plan within 12 months with FERC and DWQ. Obviously, APGI has a number of "plans" to file with FERC and other agencies after the new license is issued. It appears that most are scheduled to be filed within 24 months. EPA recommends acceleration of the filing of the Flow Monitoring Plan and DO Monitoring Plan (see comments below), given the magnitude of current violations of water quality standards below the dams. D) Water Quality - Tailwater Dissolved Oxyi!en Improvement Measures Proposal: APGI proposes to determine whether additional DO enhancement measures are needed to further improve DO conditions in the Falls and Tuckertown tailwaters after installation of aeration technology is completed at Narrows and High Rock, and after DO conditions in the tailwaters have been monitored and studied for a period of two years. Comments: EPA has concerns over the current proposal because it does not include commitments to complete DO enhancement measures at Tuckertown and Falls. The overall improvement schedule should include contingency timeframes for making additional station modifications at Tuckertown and Falls if the proposed improvements at High Rock and Narrows or operations protocols are not successful in meeting water quality standards below the dams. It would seem advantageous to build these contingencies into the new license, as opposed to relying on securing improvements via reopener clauses and potential license amendments. D) Water Ouality - Water Quality Operations Proposal/Comments: 2nd sentence, EPA recommends deleting "endeavor to" to read, "(as described above), APGI will operate the refurbished/upgraded units..." EPA also has concerns about the last sentence in this section, "Generally it is anticipated that the period of aeration operations will begin no later than May 1 of each year and will continue through November 30 of each year, unless tailwater DO monitoring indicates that water temperatures and DO conditions are such that no aeration is required." It is unclear what is meant by the last phrase in t 5/18/2006 this sentence. Low DO events do not necessarily occur in isolation; rather, during warm summer months, DO may sink below the standard for a short period (hours or days), rise back above briefly, decline again, and so on. In this instance, monitoring would show that tailrace discharges are above the standard, only to fall back below at some point in the future. It is unclear how the hydro operators will be able to react to such a dynamic condition without better definition of the linkage between the continuous monitoring results and the operations protocol. This should be qualitatively addressed in the AIP or RSA, with greater clarity occurring in the 401 certification application or the DO Monitoring Plan. D) Water Ouality - Dissolved Oxygen Monitoring Plan and Reports Proposal: APGI proposes to file the Flow Monitoring Plan within 12 months of the effective date of the new license. Comments: EPA recommends acceleration of the filing of the DO Monitoring Plan within 6 months with FERC and DWQ. Development and submittal of this plan should be one of the first priorities under the new license, given the magnitude of current violations of water quality standards below the dams. In addition, it is anticipated that much of the information needed to complete this plan will be included in the 401 certification application to the State of NC, which would seem to make it easier to file this plan more quickly. Attachment 4 - Yadkin Proiect Proposed Unit Refurbishment/Upmde and DO Enhancement Schedule Comments: As mentioned in our comments on the DLA, EPA is very interested in ensuring an expedited improvement schedule that includes completion of DO enhancements at High Rock and Narrows by 2011 (instead of 2012, as currently proposed). Here are a number of comments to address this issue, based on the timeline proposed in Attachment 4: 1) Is it possible to expedite the schedule for improvement to Narrows Unit #2, which is already approved under the existing license? Completion in CY 2007 or earlier in CY 2008 would hopefully allow for initiation of refurbishment of Unit #1 in 2008 after the new license is issued, with the ability to expedite the subsequent schedule for future improvements. At a minimum, can the improvement schedules be timed to complete construction in the summer, instead of at the end of the year, to allow for testing of the unit's aeration effectiveness during the same low DO period (late summer/early fall). This would also allow for earlier completion of some of the effectiveness testing. 2) Based on the current schedule, what is precluding APGI from operating both Units 2 and 4 during the Summer of 2008 (if Unit 2 is scheduled for completion by 3/31/08)? EPA recommends including a commitment to operate these two units starting in 2008. 3) EPA recommends initiation of the High Rock improvements in 2009 to allow for completion by 2011. Expedition of the Narrows improvements should allow for earlier initiation of the improvements at High Rock. Based on the results of the studies conducted to-date, it appears that achieving standards below Tuckertown could be problematic, relying exclusively on aeration at High Rock. This places more emphasis on completing the work at High Rock sooner so any needed improvements at Tuckertown do not extend unnecessarily in the distant future. 4) EPA recommends shortening the time-frame proposed to develop the DO enhancement action plan. It shouldn't require a year to develop an action plan for DO enhancement at either Falls or Tuckertown i Major Settlement Points for Alcoa FERC Relicensing 1. Reservoir Operating Guide Curves a. Contention centered on High Rock proposal of 4'/10'; other reservoirs acceptable. b. Lake levels related to daily average discharges, and LIP or HPMEP requirements. c. LIP (attempts to match low inflow conditions to outflow by restricting generation releases and lake level drawdowns) and HPMEP conditions agreeable to all. d. Seasonal component considers reservoir stabilization for fish spawning e. Seasonal component allows H.R. to continue to operate as storage. 2. Instream (Downstream) Flows a. Flows agreed upon by all including Progress, SC DNR and DHEC. b. Flow naturalization period from Feb. - May to enhance downstream fish spawning agreed upon by all. 3. Water Quality a. Tailwater DO improvement schedule not yet agreed upon by DWQ. b. DO monitoring plan and reporting will be written into 401 and will not likely pose issues for DWQ. c. QAPP not yet developed, but they are reported to be compiling it for submittal prior to 401 submittal. 4. Recreation Plan a. 1400 acres to be made available for purchase to State for Morrow Mountain S.P. expansion. b. Lots of additional recreation facility improvements and access points in addition to the historic 26 public recreation sites operated and maintained by Alcoa. These new sites to be taken on by county, muni or WRC. c. Still talking w/ DENR and USFS on additional acres on H.R. inflow and Uwharrie Nation Forest expansion; also potential rail line conveyance. 5. Shoreline Management Plan a. New SMP aligns more with state buffer rules related to exemptions and allowable uses, but still very strong; same 100' width requirement; applies to all reservoirs. b. Continues no private access on Tuckertown and Blewett Falls. 6. Fish Passage, Invasive Species and RTE Species Protection Plans a. Alcoa working on these plans with USFWS and WRC, DWR and NHP. 7. License Term - will define this based on negotiations outcome. 8. Sedimentation/Flooding Mitigation a. Added this from May 5 version - commiting to paying into mitigation fund for Salisbury of amount to be determined. Fund can be used for flood-proofing, facility relocation, sediment removal, etc. Will pay "amount equal to the present value of the cost of implementing the Mitigation". b. Salisbury not likely to accept this offer. 9. TMDL Process a. Although not stated specifically in the AIP, Alcoa committed $50K total or $25K/two year study to support DWQ's TMDL development. City of Salisbury Issues - Flooding, Sedimentation, land donation, water rights, lake level data. In my opinion, Alcoa has tried to address each of these, but Salisbury will likely say they fell way too short. Major Settlement Points for Progress Energy FERC Relicensing 1. Filed Draft License Application in November 2005 - DWQ filed comments. Final license application will require additional review. 2. January 2006 - Progress met with DWQ to present DO Enhancement Program Update. DWQ provided comments in writing in February. PE agreed to address most comments. Revised plan not submitted to DWQ and no further specific discussions on this plan. 3. March - minimum flows determined per DWR and mitigation needs identified. DWR, Progress and John worked this up. 4. April - PE agrees with instantaneous flows and downstream stakeholders are satisfied; this led to agreement with Alcoa on flows and helped define the remaining issues on Alcoa agreement. Other issues agreed upon. Secretary Ross pushed Progress management on additional lands and conditions. 5. May 17 revision of Comprehensive Agreement Trial Balloon - DWQ filed comments on continuous monitoring component. Progress agreed to alter trial balloon to reflect concerns. 6. Progress developed a turbine venting and enhancement plan and submitted to DWQ for comments. DWQ still needs to review and comment. 7. QAPP was submitted over two years ago. What is status of review? 8. Other state and federal agencies are generally satisfied with the trial balloon.
