Oil staining was <br />concentrated in vehicle processing areas, engine and transmission storage areas. <br /> <br />· A stormwater NPDES permit has reportedly been filed for and obtained although <br />the Stormwater Pollution Prevention Plan has not been completed yet. <br /> <br />· One aboveground fuel storage tank was observed. No underground storage tanks <br />are reported to exist. <br /> <br />Proposed Investigation <br /> <br />e <br /> <br />To assess environmental conditions at the Property, a series of shallow powered auger <br />borings are proposed to determine the depth of petroleum product impacts in areas with <br />stained soils. A portable photo ionization detector used to monitor organic vapor <br />commonly associated with petroleum product releases, will be used to monitor soil <br />conditions with depth in the field. Selected samples will be prepared and retained for <br />laboratory analysis. Constituents selected for laboratory analysis include but are not <br />limited to diesel range organics (DRO) , total recoverable petroleum hydrocarbons <br />(TRPH) , polychlorinated biphenyls (PCBs) and lead. A memorandum report <br />summarizing data collected for the Property will be prepared and submitted. Based on <br />the initial findings, additional investigative work may be necessary to characterize the <br />Property. Table 1 summarizes tasks and costs anticipated with this work plan. <br /> <br />maw:bdmem09293. wp/GO <br /> <br />e <br /> <br />B.A. LIESCH ASSOCIATES, INC. <br /> <br />13400 15TH AVENUE NORTH <br /> <br />MINNEAPOLIS, MINNESOTA 55441 <br />
