While no determination letter has been issued <br />by the MPCA relative to this release in specific consideration to the Subject Property, it is <br />evident that the concentrations do not exceed applicable regulatory criteria for drinking water, <br />and there is no indication of any shallow impacts to soil at the Subject Property for these <br />halogenated VOCs. <br />The two LUAST incidents are historical recognized environmental conditions. Based on the <br />review of revealed information, contaminated soils and groundwater were encountered on the <br />Subject Property in relation to releases from one 10,000-gallon diesel UST and one 8,000-gallon <br />gasoline UST (leak #1794), and one 12,000-gallon diesel UST (leak #16046). Both leak sites have <br />been granted regulatory closure by the Minnesota Pollution Control Agency (MPCA). <br />Additionally, the multiple closed spill incidents on the Subject Property are historical <br />recognized environmental conditions. Specifically, ten gallons of Stryrene Monomer, four <br />gallons of hydrogen peroxide (at a 20-40% concentration) and one gallon of inethyl ethyl <br />ketone were released at the Subject Property in different incidents. The most recent release <br />occurred in August, 1995. <br />N:\Technical\2238Torgerson Properties\OS Roseville Crossing\223S-OS.docx <br />1-3 <br />October 2012 <br />' ��C�4�\ <br />
