Chief-This letter supplements my remarks made at the License Renewal and Environmental Scoping Review Process meeting for the proposed license renewal at Prairie Island Nuclear Generating Plant, Units 1 and 2, held July 30, 2008 in Red Wing, Minnesota.
Concerns for the Lake City community that emerged from conversation at meetings of both the Lake City Utility Board and Lake City Common Council are a follows:
- 1.
Long-term storage of nuclear waste
- 2.
Thermal. impact 6of service water discharge on the MiSsissippi River and Lake Pepin.
We ask that the' best available water dispersion modeling be used to assess the natural ecosystem and cultural impacts of thermal discharge aid that there be a plan put in' place to mitigate adverse impacts. What follows is expanded development of our concerns related to thermal impacts. We recognize Lake Pepin, the Mississippi River, and its tributaries as interacting components of the world's third largest river system. The thermal plume of any water discharge has potential to impact:
Vertebrates and invertebrates. A thermal plume can have direct impacts such as changes in distribution of aquatic organisms (e.g. attracting fish to warmer water during winter), or cause indirect impacts such as increased exposure to predators (e.g. through concentrating prey fish in warmer waters during winter).
Ice. A thermal plume can affect the characteristics of ice or the length of the ice cover season on Lake Pepin. It is a-safety consideration, but also cultural, in that recreation on the ice is a long-standing community tradition that could be altered'because of safety concerns.'

The Pollution Control Agency, acting as it is legally required to do under the federal Clean Water Act, is working to develop a Total Maximum Daily Load (TMDL) for Lake Pepin.
It is a restoration project with set goals for the dose of pollution that the river system can handle and-still be-ased for specific proposes such as d-i1king water, fishing or swinmning_
Dissolved Oxygen. Water temperature affects dissolved oxygen levels. Increasing water temperature decreases water's ability to carry oxygen.
Endocrine Disruptors. If a thermal plume interacts with a municipal wastewater discharge plume, organisms (e.g. catfish, smallmouth bass) congregating in the warmer water may be subject to prolonged exposure to chemicals such as those found in birth control pills.
Phytoplankton and Zooplankton. Heat can result in increased production of organisms that ultimately can lead to a decrease in light and oxygen in the river and in Lake Pepin.
Parasites. Thermal effluent has been reported to influence the prevalence and abundance of parasites of fish.
As a result of these potential impacts and affects, we ask that changes in seasonal mean temperature be assessed related to the facility upgrade for the entire dispersion plume, both in the main channel of the Mississippi River and on each shore of Lake Pepin.
