Operations at Kerr Lake
The U.S. Army Corps of Engineers (USACE) is the principal decision maker on operations. The purposes served by the dam's operation are authorized or required by Federal law, and USACE is also required to consider the impacts of its practices on wildlife [1] and maintain compliance with other federal laws.A team from UNC-Chapel Hill, including Profs. Richard Whisnant at the School of Government; Greg Characklis, at the School of Public Health; Martin Doyle in the Department of Geography; Victor Flatt at the Law School; and graduate student Jordan Kern has produced a study of the Corps' ability to make operational changes at Kerr Lake.
Congressional authorizations
Authorized by Section 10 of the Flood Control Act of 1944, Pub. L. 78-534, 58 Stat. 887, 894, USACE describes the John H. Kerr Dam and Lake project as "authorized for recreation, flood control, hydroelectric power generation, fish and wildlife, and water supply."[2] The Flood Control Act authorized work at this location for "the benefit of navigation and the control of destructive flood waters and other purposes."[3] The act also permits the lake to be used for recreation[4] and allows excess power generated at the dam (currently estimated at some 426,749,000 kWh per year) to be marketed and sold.[5] Water supply storage was later authorized as a purpose for USACE reservoirs by the Water Supply Act of 1958, Pub. L. 85-500, 72 Stat. 319, 319, and USACE has been instructed to complete calculations that would allow it to enter in to a permanent water supply contract with the Kerr Lake Regional Water System and the city of Henderson, North Carolina by the Water Resources Development Act of 2007.[6]
Decision-making
In operating the dam at Kerr Lake, USACE is required by federal regulations to develop a Water Control Plan “to comform[sic] with objectives and specific provisions of authorizing legislation and applicable Corps of Engineers reports” that gives “appropriate consideration to all applicable Congressional Acts relating to operation of Federal facilities, i.e., Fish and Wildlife Coordination Act (Pub. L. 85-624), Federal Water Project Recreation Act-Uniform Policies (Pub. L. 89-72), National Environmental Policy Act of 1969 (Pub. L. 91-190), and Clean Water Act of 1977 (Pub. L. 95-217).” These plans must be kept up to date through continuing and progressive study. [7]
Decisions that require documentation under the National Environmental Policy Act (NEPA)
Federal regulations outline what actions on the part of USACE require some sort of environmental review, as well as a range of actions that are exempt from environmental review. 33 C.F.R. 230.6 declares that an Environmental Assessment (EA) and/or an Environmental Impact Study (EIS) is normally required when the Corps takes any of the following actions, each of which would constitute a significant growth or change in operations: conducting a feasibility report for the authorization and construction of major projects; proposing changes in projects that increase size substantially or add additional purposes; and proposing major changes in the operation and/or maintenance of completed projects. What constitutes a "major change" in operation and/or maintenance is not specified.
On the other hand, activities at completed projects that carry out the authorized project purposes are categorically excluded from having to produce NEPA documentation. Examples of such actions, from the regulations at 33 C.F.R. 230.9(b), include routine operation and maintenance actions, general administration, equipment purchases, custodial actions, erosion control, painting, repair, rehabilitation, replacement of existing structures and facilities such as buildings, roads, levees, groins and utilities, and installation of new buildings utilities, or roadways in developed areas.
Stakeholders
There are many stakeholders and several key decision makers involved in the operations of Kerr Lake, as with other federally managed reservoirs.
Interested institutional parties include the States of North Carolina and Virginia, notably their water resources and wildlife agencies; The Nature Conservancy, which has made the Lower Roanoke river downstream of the lake one of their major areas of focus for conservation; water supply customers such as the Kerr Lake Regional Water System and City of Henderson (see "congressional authorizations," above); potential water supply customers; the Southeastern Power Administration (SEPA) (website here), which markets surplus power from federally managed impoundments at rates approved by the Federal Energy Regulatory Commission (FERC); and purchasers of this power, including a private, investor-owned utility, Dominion Resources, Inc. (NYSE: D) and its corporate subsidiaries, particularly Dominion Generation, as well as public power entities such as the Electricities and Electric Coops.
The following flow charts are based on information from the USACE Water Control Manual for Kerr Lake[1] and the Water Wiki. They are meant to conceptualize the flow of electricity, water, and dollars through the Kerr Lake system. The current version of the Water Control Manual available on the USACE website is dated 1995; therefore, some information contained in the flow charts is speculative. As more current information becomes available, the flow charts will be amended.
Electricities in particular
The NC Eastern Municipal Power Agency (NCEMPA) , members of which are shown in green on the map on this page, may use some power from SEPA, although it
purchases additional capacity and energy to meet the needs of the members through a Supplemental Load Agreement through December 31, 2017 with Progress Energy Company (PEC). Under this contract, NCEMPA agreed to purchase from PEC and PEC agreed to sell to NCEMPA, supplemental capacity and associated energy to meet all the remaining requirements of the members through the term of this agreement. The contract represents about 25 percent of NCEMPA’s total annual energy needs and roughly 35 percent to 40 percent of NCEMPA’s average monthly capacity requirements.[8]
The NC Municipal Power Agency Number 1, members of which are shown in blue on the map, notes in its 2007 CAFR that it has the right to purchase 60 MW from SEPA. Since these members are in Piedmont and western N.C., does this SEPA power include power from operations at Kerr?
The SEPA Annual Report for 2004 (latest available on the SEPA website as of June 30, 2008) notes:
Amendments were agreed to, effective January 1, 2004, to the North Carolina Electric Membership Corporation (NCEMC) members’ customer contracts in the VEPCO [now Dominion] service area. These amendments allow members to self-schedule their allocations of government power. Preference customers in their area designated NCEMC as their scheduling agent and Southeastern negotiated a scheduling contract with NCEMC, also effective January 1, 2004.[9]
