Procedural Context Entergy Nuclear owns and operates a nuclear power station in Vernon, Vermont, located on the west shore of the Connecticut River at the Vernon Pool. The facility is a boiling water reactor which began operating in 1972. A portion of the thermal output of the facility produces electricity; the remainder is removed as heat through a circulating water system that passes by a condenser. The condenser cooling water is either discharged into the Connecticut River or into the atmosphere through mechanical draft cooling towers. Discharges from the Entergy Nuclear facility into the Connecticut River are regulated under the National Pollutant Discharge Elimination System (NPDES) program, a federal program which the State of Vermont is authorized to administer. The relationship between the requirements of the federal statute and regulations and Vermont’s Water Pollution Control Act and associated regulations is at issue in this appeal. Pursuant to the federal and state statutes, discharge permits are issued for fixed terms not to exceed five years. 33 U.S.C. §§1392(a)(3), (b)(1)(13); 10 V.S.A. §1263(d)(4). Permit applicants may continue to operate pursuant to an expired permit while the renewal proceedings are pending. United States v. Con Agra, Inc., No. CV 96-0134-S-LMB at *20 (D. Idaho 1997) (unpublished). A renewal permit is required to be analyzed and “issued following all determinations and procedures required for initial permit application.” 10 V.S.A. §1263(e). In July of 2001, the ANR issued Discharge Permit No. 3-1199 (the 2001 Discharge Permit) to then-Vermont Yankee Nuclear Power Corporation., authorizing it to discharge condenser cooling water2 into the Connecticut River, subject to temperature-related restrictions applicable to the following two periods each year: from October 15 through May 15, and from May 16 through October 14. The restrictions in the 2001 Discharge Permit

2 The permit also authorizes and regulates the discharge of service water, low-level radioactive liquid, plant heating boiler blowdown, water treatment carbon filter backwash, stormwater runoff, and demineralized trailer rinsedown water, none of which is at issue in the present permit amendment application. In addition, the permit authorizes the discharge of cooling water from four service water pumps.

2 applicable from mid-October through mid-May regulated the maximum temperature in the river, the rate of change of the river temperature, and the increase of temperature above ambient levels, while the restrictions applicable from mid-May through mid-October regulated the allowable increase of temperature above ambient levels, as expressed in a chart relating the allowable increase to the specific ambient levels (Part I, §6(b). The 2001 Discharge Permit also established an Environmental Advisory Committee (EAC), comprising representatives of the Vermont, New Hampshire, and Massachusetts environmental and fisheries programs, plus the coordinator of the United States Fish and Wildlife Service’s Connecticut River Anadromous Fish Program, and provided that the Vermont Yankee facility’s Chemistry Manager or designee would serve as the Committee’s administrative coordinator and secretary. The paragraph establishing the EAC (Part I, §11, at p. 7) stated that the EAC was “advisory in function” and required the permittee to meet with the EAC “as often as necessary, but at least annually, to review and evaluate the aquatic environmental monitoring and studies program” established in Part IV of the permit. The 2001 Discharge Permit allowed the temperature-related restrictions to be modified during an emergency shutdown, and authorized experimental test programs with alternative thermal limits to be administered as approved by the EAC and authorized in writing by the ANR. The 2001 Discharge Permit allowed the Secretary of the ANR to “reopen and modify” the permit, after notice and opportunity for a hearing, “to incorporate more stringent effluent limitations for control of the thermal component” of the discharge, based on a determination that “open cycle operation is having an adverse effect [o]n resident or anadromous fish species in the river.” The 2001 Discharge Permit was amended shortly after its issuance to account for two existing stormwater discharge points. It was amended in 2002 due to the transfer of ownership of the Vermont Yankee facility to Entergy Nuclear. It was amended in 2003 to replace a named chemical, to add a monitoring location, and to modify the fish impingement sampling requirement (to collect samples from circulating water traveling screens) so this type of sampling is not required when temperatures are below freezing. It was amended in 2004 to allow an internal facility plumbing change to divert a certain amount of cooling water from another internal source to the service water pumps. In February of 2003, Entergy Nuclear applied for the permit amendment that is the

3 subject of the present appeal: to increase the temperature of the Connecticut River by an additional one degree Fahrenheit (1° F), as determined at monitoring Station 3 as compared with upstream monitoring Station 7, during the entire mid-May through mid- October “summer” period. The ANR issued a Draft Amended Permit for public comment and held a public hearing in November of 2005. On March 30, 2006 (making the amendment applicable to the then-not-yet-expired 2001 Discharge Permit), the ANR issued the 2006 Permit Amendment. It allowed the requested increase for the period from June 16 through October 14, but imposed the existing limitations of the 2001 Discharge Permit for the period from May 16 through June 15. The 2006 Permit Amendment included a new provision setting a limit on the maximum temperature in the river during the mid-June through mid-October period. Part I, §6(c), at p. 5. The 2006 Permit Amendment also included a new provision in Part IV (governing Environmental Monitoring Studies), at p.
