URS <br /> BRW, Inc. <br /> January 17,2001 <br /> Mr.Jay Hartman <br /> Director of Public Works <br /> City of St.Anthony <br /> 3301 Silver Lake Road <br /> St.Anthony,MN 55418-1699 <br /> RE: Proposal for Phase II Investigation <br /> Central Park Redevelopment <br /> Dear Mr. Hartman: <br /> Thank you for the opportunity to present this proposal for completion of a Phase II investigation in conjunction <br /> with the redevelopment of Central Park. This proposal is based in part on the results of the Phase I Environmental <br /> Site Assessment (Phase I ESA) completed by BRW, which revealed the following recognized environmental <br /> conditions(RECs)in connection with the property: <br /> 1. A portion of the Central Park property was utilized as dumping grounds between approximately 1949 and <br /> 1954. The American Legion Post#513 reportedly operated the dumping grounds with the approval of the St. <br /> • Anthony Village Council. Dump debris was encountered in one of five geotechnical borings completed at the <br /> property in December 2000. <br /> 2. A suspected petroleum release to groundwater was identified in two of the five geotechnical borings. The <br /> suspected release was reported to the MPCA to comply with notification requirements. Several potential <br /> sources of the release were identified by the Phase I ESA, however, the exact source of the suspected release <br /> is not yet known. <br /> 3. An underground storage tank release was identified during removal of a heating oil tank at the former St. <br /> Anthony Community Center property located south/southwest of and adjacent to the property. <br /> 4. Groundwater contamination from the Twin Cities Army Ammunition Plant (TCAAP) has impacted bedrock <br /> aquifers at the property. Two monitoring wells related to the TCAAP release are located at the Site. <br /> Pretreatment results from City of St. Anthony Village water supply wells located adjacent to the property <br /> indicate that bedrock aquifers are impacted by low levels of trichloroethene and its degradation products. <br /> Minnesota Department of Health well records for the monitoring wells also indicate up to nine feet of"man- <br /> made fill'. <br /> RECs #1 and #2 will be addressed by the Phase II investigation. The MPCA leak site file for the underground <br /> storage tank release (REC #3) has been closed, meaning that no further investigation or corrective action is <br /> required at this time. Investigation and corrective actions related to the TCAAP release (REC #4) are being <br /> addressed by the USEPA. The TCAAP release should not need to be addressed in conjunction with the park <br /> redevelopment due to the nature of the release(deep aquifer contamination)and the corrective actions completed <br /> to date. <br /> • Thresher Square <br /> 700 Third Street South <br /> Minneapolis, MN 55415 <br /> 612.370.0700 Tel <br /> 612.370.1378 Fax <br />
