Review current United States Geological Survey (USGS) topographic maps to identify the <br /> physiographic setting of the subject property and provide a statement on the local geologic, soil <br /> and groundwater conditions based on our general experience and sources such as geologic maps <br /> and soil surveys. <br /> 10. Conduct a visual reconnaissance of the subject property and adjacent properties to identify visible <br /> evidence of RECs. <br /> 11. Identify the source(s) of potable water for the subject property and current heating and sewage <br /> disposal system(s) used at the subject property, if any,and their age if readily available. <br /> 12. Identify data gaps relative to the Phase I ESA study findings. <br /> 13. Provide a written summary of the Phase I ESA results and identified RECsl, if present) along with <br /> our opinion and recommendations regarding the potential for contamination by hazardous <br /> substances at the subject property and the significance of any data gaps identified. <br /> The scope of services does not include an environmental compliance audit or an evaluation for the <br /> presence of lead-based paint,toxic mold, polychlorinated biphenyls (PCBs) in light ballasts, radon, lead in <br /> drinking water,asbestos-containing building materials or urea-formaldehyde insulation in on-site structures <br /> or debris or other potentially hazardous building materials. Soil, surface water, groundwater, or soil gas <br /> sampling and chemical analysis are not included as part of this Phase I ESA scope of services. <br /> The CITY shall provide the names and phone numbers of key individuals with knowledge of property use <br /> history of the subject property and notify us if tax parcel maps do not accurately reflect the boundaries of <br /> the subject property.Additionally,the City shall provide the following helpful information,if readily available, <br /> prior to the start of our study: 1)copies of any past ESA and/or audit reports; 2)environmental permits; <br /> 3) registrations for underground and aboveground storage tanks; 4) material data safety sheets for <br /> hazardous substances used or stored on the subject property (if any); 5) community right-to-know plans <br /> pertaining to the subject property; 6)safety plans pertaining to on-site facilities; 7) reports regarding <br /> geotechnical and/or hydrogeologic conditions;8) notices of environmental violations and/or environmental <br /> liens or property use restrictions, including title reports that may reflect this information; 9)specialized <br /> knowledge or experience and commonly known information of which you are aware regarding the subject <br /> property and related environmental conditions; and 10) explanation for any significant difference between <br /> purchase price and market value, if the subject property is not known to be contaminated. <br /> GeoEngineers,Inc. <br /> File No.0661-108-00 <br />
