At' <br />Mr. Lester F. Schmiedt, et. al. -2 26 April 2002 <br />The PA discusses information obtained from the site and states the site has "contaminated soil, a surface <br />impoundment, and heavy metal contamination." The PA recommends further action by: 1) reviewing <br />historical aerial photographs of the site, 2) getting additional information regarding hazardous materials <br />stored, handled, and disposed on the site, 3) obtaining hydrogeology information to evaluate possible <br />threats to groundwater from potential soil pollution, 4) collecting soil samples near surface • <br />impoundments and all waste streams, and 5) analyze samples for pesticides, fertilizers, and heavy <br />metals. <br />The PA Review summarizes the PA, notes that Tri-Ag is listed in the Resource Conservation Recovery <br />Act database as a generator of hazardous wastes, and recommends a medium priority site inspection be <br />conducted under Comprehensive Environmental Response, Compensation, and Liability Act <br />(CERCLA). <br />The Site Inspection Report was prepared by an environmental company under the direction of the United <br />States Environmental Protection Agency based on the review of the PA and PA Review. The Site <br />Inspection Report notes that tanks and trucks used for pesticide application were rinsed in the field, the <br />site generates waste-oil and used lead-acid batteries from equipment maintenance, and underground <br />storage tanks were removed in about 1968. Groundwater is at about 15 feet below ground surface. The <br />Site Inspection Report recommends a medium priority CERCLA site inspection with focus on <br />determination if a release to the environment has occurred. <br />The Ellt is an environmental impact report that discusses the "Plan Area" proposed for redevelopment. <br />The "Plan Area" includes the site. According to the EIR, the medium priority CERCLA site inspection <br />recommended by the PA Review and the Site Inspection Report has not been conducted. The ER notes <br />that applications of pesticides may have caused soil and groundwater pollution and could expose persons <br />to hazardous waste residues, which is a "health threat posed through possible inhalation, ingestion or <br />corporal contact." The ER recommends a "soil contamination investigation" including: <br />Review of available records of pesticide types, application practices, storage areas, and disposal <br />procedures; <br />Review of records of unauthorized pesticide releases or spills; <br />Examination of at least four generations of historical aerial photographs; <br />A hydrogeologic and groundwater usage investigation; <br />A soil sampling program; <br />A groundwater sampling program; <br />A waste stream sampling program; and <br />A report summarizing all of the obtained historical and sampling information. <br />Based on correspondence from Ms. Nicholson, homes have been built adjacent to the site and a school is <br />proposed in the area, which raises additional health concern issues. <br />Therefore, an investigation is needed to determine if groundwater and soil are polluted at the site. By <br />28 June 2002, please submit a work plan to investigate soil and groundwater pollution. Analyses for <br />soil and groundwater samples should include, but not be limited to, pesticides, fumigants (including <br />ethylene dibromide, 1,3-dichloropropene, and dibromochloropropane), fertilizer constituents (including <br />ammonium, nitrate, nitrogen, phosphate, and sulfate) carbamates, organophosphates, metals, total
