In re Morrisville Hydroelectric Project Water QualityAnnotate this Case
The issue presented to the Vermont Supreme Court in this case involved a state water-quality certification made pursuant to the federal Clean Water Act (CWA), issued by the Vermont Agency of Natural Resources (ANR) for the operation of hydroelectric dams. ANR certified three dams operated by Morrisville Water and Light (MWL) and imposed conditions, including those to control the minimum amount of water released from each dam to support habitat for fish. MWL appealed these conditions to the Environmental Division. American Whitewater and Vermont Paddlers’ Club (collectively the Paddlers) also appealed, arguing that the conditions at one facility did not allow for whitewater boating. The Environmental Division rejected ANR’s flow rates and imposed MWL’s proposed flow rates, affirmed ANR’s conditions regarding a winter drawdown for one site, and imposed scheduled releases of water as requested by the Paddlers. ANR appeals and MWL cross appeals. After review, the Supreme Court concluded the Environmental Division erred in rejecting ANR’s interpretation of its antidegradation policy and methodology for calculating flow rate, and affirmed the Environmental Division on the winter drawdown and timed releases for the Paddlers at the Green River facility.
