Attached are air photos for the former PNA Lathrop SWI site.AGE has noted some eatures for discussion and <br /> clarification. Please note some items of interest like waste features are evident;while notable areas of vegetation or <br /> undisturbed areas are visible. Our project boundary condition and therefore the project goals are becoming clear.Our <br /> inclusion of the 1985 birds eye air photo is likely the final image prior to the termination of use by PNA Lathrop,for the <br /> project area.AGE will continue to search for more photos near that time frame. <br /> Please call our office with any questions,or additional items required prior to Friday. <br /> William Little <br /> California Professional Geologist#7473 <br /> Advanced GeoEnvironmental, Inc. <br /> Environmental .
