k.Description of Request:Exelon Generation Company, LLC requests Commission approval for a variance of the minimum flow requirement of the project license. Due to drought conditions and low river flows in the Susquehanna River, Exelon requests that they be allowed immediately to include plant leakage of about 530 cubic feet per second (cfs) in the required minimum flow discharge until September 14, 2012, or until flow conditions improve where the Conowingo Project no longer requires leakage be included as part of the minimum flow requirement. According to the license, for the period June 1 through September 14, annually, Exelon must provide a minimum flow release (not including leakage) below the dam of 5,000 cfs, or inflow (as measured at the USGS gage 0156000 at Marietta, PA), whichever is less. During the fall period, September 15 through November 30, Exelon is required to release a minimum flow of 3,500 cfs not including leakage, or inflow to the project whichever is less, as measured at the Marietta gage.
Exelon is concerned about the ability of the Conowingo Project to maintain an adequate pond level and storage capacity during the current low flow period. Maintaining storage is necessary for generation and to ensure an adequate water supply for recreational and consumptive uses of the Conowingo Reservoir to include operation of Peach Bottom Atomic Power Station and Muddy Run Pumped Storage Project. Including plant leakage in the minimum flow discharge will contribute to the maintenance of these project water uses during this low flow period. During the period of the minimum flow variance, Exelon will conduct daily monitoring of the Susquehanna River below the dam for potential environmental effects. If any abnormal or adverse conditions are observed, Exelon will promptly notify the Maryland Department of Natural Resources. In addition, Exelon agrees that during the period of the variance, it will not operate more than two units, each rated at 54,000 horsepower, unless PJM Interconnection LLC directs Exelon to operate in peaking mode: (1) As a result of a system emergency; or (2) to manage Conowingo pond levels.
