(NOA) has been retained by Ms. Suzanne Stone of Kimball <br /> Hill Homes to perform a Phase II Environmental Site Assessment (Phase II) as part of their due <br /> diligence process for the subject Site. Kimball Hill Homes intends to develop the site as a <br /> residential subdivision. <br /> NOA previously completed a Phase I Environmental Site Assessment for the Site,which identified <br /> the following potential on-site conditions: <br /> 1. Records research indicates that a 550-gallon underground gasoline storage tank was installed <br /> immediately adjacent to the subject property in 1957. The tank was removed without a <br /> permit approximately five years ago. <br /> 2. The subject property has been used for agriculture in the past. <br /> 3. Agricultural chemicals have been stored in the barn on the subject property. Oil stains to <br /> soil and open containers of waste oil were observed in and around the bam. <br /> The Phase II will investigate the Site for evidence of any impacts to soil from the potential <br /> conditions listed above. <br /> The San Joaquin County Environmental Health Department (EHD) requires a workplan be <br /> prepared before drilling permits can be issued for environmental investigations. A drilling permit <br /> will be required for the proposed boring near the adjacent former underground storage tank. <br /> The workplan is organized into the following sections: general information, health and safety plan, <br /> soil sampling procedures,proposed time schedule for work, and report preparation. We understand <br /> the investigation may not proceed until after EHD staff approval of the workplan and issuance of a <br /> drilling permit. A California licensed geologist will oversee the investigation on the Site. <br /> LODI ■ SACRAMENTO ■ MODESTO <br /> ENVIRONMENTAL DIVISION 902 Industrial Way,Lodi,California 95240 11111209.367.3701 ■ 209369.4228 fax ■w .no <br />
