April 25, 2003 The Honorable Jim Doyle Governor, State of Wisconsin 115 East, State Capitol Madison, WI 53702 Carol A. Stemrich Public Service Commission of Wisconsin P.O. Box 7854 Madison, WI 53707-7854 SUBJECT: Comments of the Village of Shorewood Hills concerning the proposed West Campus Co- generation Facility (WCCF) Public Service Commission Docket No. 05-CE-121 Dear Governor Doyle and Ms. Stemrich: The Board of Trustees of the Village of Shorewood Hills has directed me to send this letter, following a report that was presented at the Board's meeting on April 21, 2003, by our Ad Hoc Committee for study of the proposed West Campus Co-generation Facility (WCCF). We have addressed this letter to you as potential decision-makers with respect to the question of whether another power plant should be constructed on the University campus. The Village asks you to consider the concerns of the Village, both with respect to the decision-making process, and with respect to the potential impacts that the facility may have on the environment and the quality of life of those who live in close proximity to the site of the proposed plant. In addition, we ask that this letter be made part of any official record that will reflect your consideration of this matter. I. Summary The Village was incorporated in 1927. It is bordered on the east by the Madison campus of the University of Wisconsin, on the north by Lake Mendota, and on the south and west by the City of Madison. If the WCCF were approved, the facility would be located less than a mile from the eastern border of our Village. The Village has not taken a position on the ultimate question of whether the WCCF or a smaller facility ought to be built at the site. However, it has a number of concerns about both the decision-making process and the potential impacts that such a facility could have on the environment and the quality of life of Village residents. These may be summarized as follows: (1) the Village believes that the Public Service Commission, the University and the State should each conduct rigorous cost/benefit analyses, with a high degree of scrutiny, as to whether the WCCF is truly needed, whether the proposed site is appropriate in view of its close proximity to hospitals and residential areas, and whether there may be one or more preferable alternatives that would provide for all or part of the respective needs of the University and MGE; (2) while the Village recognizes that the University and the State intend to make a final decision on the proposed WCCF on about May 7, 2003, in order to permit provisions to facilitate construction to be incorporated into the 2003-2005 state budget, the Village believes that the May 7 deadline does not provide sufficient time to ensure that adequate consideration will be given to the concerns of the Village that are stated in this letter; (3) if any power plant is built at the proposed site, the Village believes that there should be no net degradation of the environment, and that any permits that may be required for the construction or operation of such a power plant should contain legally enforceable conditions or limits to ensure the achievement of that goal. I. General Comments The plan for the WCCF would place an industrial facility in close proximity to residential neighborhoods that are located within: (1) the Village of Shorewood Hills; (2) areas within the Regent Neighborhood of the City of Madison that include University Heights and the Old University Avenue Corridor; and (3) portions of the University campus that are devoted to apartments or dormitories in Eagle Heights, University Houses, and the area along the shore of Lake Mendota to the east of Willow Creek. It would also be located in close proximity to the three existing medical facilities of the University of Wisconsin Hospital and Clinics, the Veteran's Administration Hospital, and the Waisman Center, as well as to a proposed new children's hospital. Accordingly, as noted above, the Village believes that rigorous cost/benefit analyses should be conducted, with a high degree of scrutiny, as to whether the WCCF is truly needed, whether the proposed site is appropriate in view of the close proximity of hospitals and residential areas, and whether there may be one or more preferable alternatives that would provide for all or part of the respective needs of the University and MGE . In considering whether alternatives may be preferable, the Village believes that consideration should be given to whether all or part of the projected benefits could be obtained with lower net costs to: (1) state taxpayers; (2) utility ratepayers; (3) the environment; (4) the health of sensitive populations in adjacent areas that include children, hospital patients and the elderly; and (5) the overall quality of life of neighboring residents. A consultant's report on potential alternatives will not be presented to the University in final form until April 25, 2003. Given that, the Village believes that the current deadlines that call for the University to decide how to proceed by May 1, and for the Department of Administration to choose between the options proposed on behalf of the State by May 7, are insufficient to assure that adequate consideration will be given to the concerns of the Village that are stated in this letter. If it is determined that a power plant must be built on the proposed site, the Village believes that the plant should be designed, and mitigation measures should be required, with the goal of assuring that there will be no net degradation of the environment. The Village also believes that any permits that may be required for the construction or operation of such a power plant should contain legally enforceable conditions or limits to ensure that there will be no net degradation of the environment. II. Water Resources The draft environmental impact statement (DEIS) states (pp. 107-108) that the groundwater in the Madison area has been depleted by withdrawals of water from Madison-area aquifers by wells, and by development that has reduced the amount of surface water that can infiltrate into the soil to replace the volumes that have been withdrawn. While the groundwater normally would help to recharge the waters of area lakes, the DEIS states (p.108) that Lake Mendota currently recharges the groundwater across the southern two-thirds of its lake bed, and that Lake Monona recharges the groundwater across the entire area of its lake bed. The Village understands that the current plan for the WCCF includes a design of the plant, and proposals to mitigate withdrawals of ground water, that would be consistent with the view of the Village that there should be no net depletion of groundwater in the Madison area as a result of the operation of a power plant on the site. Potential mitigation projects are under consideration at four sites (see DEIS at 120-123), which would encourage surface water to infiltrate or percolate into groundwater aquifers to replace groundwater that would be withdrawn from a well near Mud Lake. A plan for storm water management measures that would promote infiltration within the Willow Creek watershed has already been created as the result of the work that was done, with Village participation, by a multi-jurisdictional storm water task force in 2001. On the basis of that work, and on the presentation set forth in the DEIS, the Village believes that the implementation of plans for infiltration projects at one or more of these sites should be required as a condition for building the WCCF or an alternative plant, and that priority should be given to the proposed locations at Rennebohm Park and the Hill Farms State Office Building in the City of Madison. In addition to assuring that there would be no net depletion of ground water resources as a result of the WCCF, the proposed infiltration projects at those sites could help to alleviate periodic flooding at the intersection of University Avenue and Midvale Boulevard, and in the University Avenue corridor to the east of that intersection, which was a concern of the 2001 storm water task force. III. Noise Levels The noise level survey that MGE commissioned for the DEIS (p. 168) does not contain any measurements of ambient noise levels within the Village and fails to reflect the results of any modeling that would predict the potential impact of the WCCF on noise levels within the Village. MGE subsequently issued a paper stating that it had monitored background noise levels of 47 dBA at two locations within the Village, and predicted that the potential sound of the WCCF "is expected to be" 31 dBA at one of those sites, and 27 dBA at the other, which led MGE to conclude that the WCCF "will not have a cumulative effect on background noise in Shorewood Hills." However, many Village residents have complained that the current levels of noise that are emanating from the West Campus area are unacceptably loud and intrusive, particularly the noise that emanates from the ventilation systems of the new Pharmacy Building and the recent addition to the Waisman Center. The DEIS notes (p. 166) that a change of 3 dBA is barely perceptible to the human ear, that a change of 5 dBA is perceptible, and that a change of 10 dBA is perceived as either twice or half as loud. The DEIS also points out (p. 166) that noise level scales "are logarithmic rather than linear," which means that the noise levels emitted by two different noise sources "at the same dB level would have a combined noise impact of 3dB greater than either source alone." Representatives of the Village have asked the University to take steps to abate or mitigate the noise levels that are emanating from the Pharmacy Building and the Waisman Center addition, but to date, efforts to secure an abatement or mitigation of that noise have not been successful. In view of the difficulty of securing mitigation or abatement of noise levels emitted from existing sources, the Village believes that the final EIS should be based on additional monitoring of existing noise levels and an independent evaluation by the Department of Natural Resources, or other appropriate agency, as to the potential impact of the WCCF, in order to ensure that the existing problems will not be exacerbated. In this context, the DEIS notes (p. 172) that mitigation measures could include "acoustical hoods or boots for interior parts of the plant or barriers erected or suspended on the outside at strategic locations." If a power plant is built on the site, the Village believes that the plant should be designed and/or mitigation measures should be required, with the goal of assuring that there will be no audible noise from the WCCF--which would degrade the quality of life for the residents of adjacent neighborhoods and hospitals--even if the existing levels of noise from the Pharmacy Building and the Waisman Center are abated or mitigated at some point in the future. IV. Light Pollution The development of the West Campus has resulted in a sharp increase in sources of ambient light that are visible to residents of the Village. The Village believes that the proposed WCCF should be required to comply with the terms of Dark Skies Initiative, with the minimum amount of lighting that may be necessary, and light fixtures that will focus any necessary light downward. V. Air Quality As noted above, the WCCF would be an industrial facility that would be built in close proximity to hospitals and residential neighborhoods. The DEIS points out (pp. 94-95 and 98-99) that the WCCF would emit several regulated pollutants, including sulfur dioxide, nitrogen oxides, carbon monoxide, particulate matter and certain other air pollutants that the Environmental Protection Agency has identified as hazardous. The DEIS also points out (p. 100-101) that children and the elderly are particularly susceptible to certain air pollutants, which indicates that there could be higher societal costs from operation of the WCCF on a site that is in close proximity to hospitals and residential neighborhoods. The WCCF would support further expansion of the West Campus area, which has already created quality of life issues for Village residents in the form of increased noise, increased traffic, and increased light pollution, as well as an indeterminate degradation of air quality as a result of the heavier traffic, the use of more chemicals in West Campus facilities and laboratories that may escape into the ambient air, and the increased burning of fossil fuels at the existing Walnut and Charter Street plants to meet the needs of West Campus buildings for steam and chilled water for heating and air conditioning. The DEIS states (p. xix) that "modeling conducted by DNR staff concludes that the proposed project would result in a net increase in fine particulate and other pollutant concentrations in the vicinity of the plant, compared to those measured at an existing monitoring station located near the intersection of University Avenue and Franklin Street." While the Village is not in a position to question or validate the air quality analysis that is set forth in the DEIS, or the overall conclusion that the facility would meet existing federal air quality standards for regulated pollutants, the Village is concerned about the conclusion of the DEIS (p. 100) that "there will be an increase in emissions" of particulate as a result of the proposed project, and accordingly, "some additional likelihood that sensitive individuals may experience increased symptoms as a result of this project." In this context, the Village understands that the results of monitoring at one location close to the proposed site of the WCCF have indicated that the City of Madison may be close to violating the National Ambient Air Quality Standards (NAAQS) for particulate matter, and that the WCCF could produce up to 50 pounds per hour of particulate matter for short periods when fuel oil may be used for combustion. The Village also understands that the City of Madison may be close to violating the applicable Ambient Air Quality Standards for sulfur dioxide and ozone. The Village is particularly concerned that the additional emissions of particulate, when combined with additional emissions that may be anticipated from other sources as the Madison area continues to develop, could contribute to a violation of the NAAQS in the future. On that point, the Village believes that necessary permits should contain a limit or condition that would impose a legally enforceable requirement that natural gas be used for 99 per cent of operations, in order to limit the use of fuel oil for combustion to one per cent of operations or less. In addition, the Village understands that there have been some discussions about mitigating the potential for additional particulate emissions by funding natural gas powered vehicles to reduce the levels of particulate that are currently emitted in the area by diesel trucks and buses, and believes that such this type of mitigation alternative could also be made a condition of necessary permits. The Village also believes that the proposed WCCF should be considered in a broader context, not merely in isolation as a facility that would comply by itself with existing air quality standards, but instead as one of many sources of potential for additional pollution that could contribute to a violation of the applicable NAAQS at some future time. In this context, the Village understands that the University may have the ability to select and use cleaner burning fuels at the existing Walnut and Charter Street plants, which may provide an opportunity to assure, or to help assure, that there would be no net degradation of air quality as a result of the WCCF. Under these circumstances, the Village believes that there ought to be consideration of the extent to which mitigation measures may be implemented at the other power plants in the central Madison area that are operated by MGE, by the University, or by the State of Wisconsin, in order to determine whether the implementation of such mitigation measures might wholly or partially offset the anticipatedincrease in emissions of both particulate and other regulated pollutants that would result from building the WCCF. In short, if a power plant of any size must be built on the proposed site, the Village believes that the plant should be designed, and mitigation measures should be required, with the goal of assuring that there will be no net degradation of the air quality in the central Madison area that includes the Village of Shorewood Hills. VI. Errors in the DEIS The DEIS contains an error at p. 154, where it is stated that "The Village [of Shorewood Hills] does not have a Master Plan." The Village does have a master plan for the commercial corridor along University Avenue that was adopted in the early 1990's. In addition, the Village is in the process of developing a Comprehensive Plan in compliance with Wisconsin's new Smart Growth law (Wis. Stat. 66.1001). It appears that there is another error in the DEIS at p. 108, where it is stated that the Blackhawk Golf Club uses 1.87 MGD (million gallons per day) of water from Lake Mendota. Monroe Miller, the Greens Superintendent for the Club, supplied the following data on water usage at the Club during the past six years. We calculated the gallons used per day by assuming the Country Club irrigates the course on average 81 days per year--approximately 3 times/week from May 1 to October 31. The actual number of days water is withdrawn for irrigating will vary considerably each year, depending on weather conditions. Year Total Gallons Used/Year Total Gallons Used/Day 1997 12,457,000 153,790 1998 19,979,000 246,654 1999 14,138,000 174,543 2000 10,278,000 126,889 2001 13,422,000 165,704 2002 14,875,000 183,642 AVERAGE 14,192,000 175,204 VII.
