1 ENVIRONMENTAL SUMMARY OF CATALYST AREA 1 Phase I Environmental Site Assessment and Phase II Environmental Site Assessment for 55 South River Street. Environmental Response Program WDNR File Review for, Court Street (BRRTS # ), closed November 15, Catalyst Area #1 Leaking Underground Storage Tank WDNR File Review for, 59 South Franklin Street (BRRTS # ), closed February 26, Leaking Underground Storage Tank WDNR File Review for Site #2, 59 South Franklin Street (BRRTS # ), closed October 9, S Franklin Street 55 S River Street The property at 55 South River Street may contain former underground storage tanks. The Phase II Investigation has determined the presence of VOCs, PAHs, arsenic, and lead in soil and groundwater. Lead concentrations in soil are potentially hazardous wastes. The property adjacent to the Court Street Bridge had low levels of petroleum hydrocarbons detected during a Phase II Investigation in Levels were not sufficient to trigger a full scale investigation and the site was closed. Small amounts of petroleum contaminated soil may be present that may be reused on site or disposed of as a special waste. Court Street The property at 59 South Franklin Street was a former gasoline filling station and eight USTs were discovered in 1996 and removed in Three additional USTs were discovered in Residual soil contamination remains at depth and residual and declining groundwater contamination was noted on the property. The case files were closed in 1998 and residual groundwater contamination was unlikely to affect neighboring properties. Primary concerns are potential impacts from contamination detected at 55 South River Street. Development would be limited to areas other than the property and downgradient of the site. Complete the leaking underground storage tank investigation at 55 South River Street. Use natural attenuation and an engineered barrier or selective removal to manage residual contamination. Special wastes disposed of at a cost of $65 per ton and hazardous waste disposal approximately $200/ton. Sampling, engineering fees, and WDNR review fees are needed in addition. Cost unknown until investigations are complete. Complete the leaking underground storage tank investigation at 55 South River Street. Remove contaminated soils From site at a cost of $65 per ton for special waste and approximately $200/ton for hazardous waste. Sampling, engineering fees, and WDNR review fees are needed in addition.

Marshall Property 119 W Court Street Environmental Response Program WDNR File Review for, Court Street (BRRTS # ), closed November 15, Leaking Underground Storage Tank WDNR File Review for, 59 South Franklin Street (BRRTS # ), closed February 26, Leaking Underground Storage Tank WDNR File Review for Site #2, 59 South Franklin Street (BRRTS # ), closed October 9, Mercy Health Systems S Franklin Street Overton Property 158 S Franklin Street Cullen Property 170 S River Catalyst Area #6 Cullen Property at 170 South River Street closed with a structural impediment preventing removal of all contaminated soil. Former Wisconsin Power & Light, 123 South River Street closed with engineered barrier with continuing obligation, residual soil and groundwater contamination consisting of chlorinated hydrocarbons. Potential vapor issues. The property at 59 South Franklin Street was a former gasoline filling station and eight USTs were discovered in 1996 and removed in Three additional USTs were discovered in Residual soil contamination remains at depth and residual and declining groundwater contamination was noted on the property. The case files were closed in 1998 and residual groundwater contamination was unlikely to affect neighboring properties. The Overton property had a heating oil tank which was reported to the WDNR based upon odors noted during closure but test results indicated no residual contamination. No impact expected on catalyst area. Mercy Health Systems has approximately 2 cubic yards (3 to 4 tons) of DRO contamination located 10 feet below ground surface next to the existing building. Disposal will be required if disturbed but no other impact is an issue. There are no continuing obligations other than the structural impediment at the Cullen property in catalyst area. Risks have been addressed, although residual contaminated soils encountered during construction will require characterization and disposal. Contaminated soils at Cullen property, Mercy Health Systems, and other sites could be removed regardless of construction, although there is little direct benefit to doing so. Court Street property may have low level residual soil contamination, but is not likely to impact catalyst area. Catalyst area has few obligations. Sites can be developed as is, but contaminated soils encountered will need to be characterized and disposed of (approximate cost $65/ton). There is likely less than 200 tons of soils that would be encountered during construction that will require disposal. Total cost of disposal is likely less than $13,000.
