to be contain low concentrations of lead, ranging from 4.8 to 27.2 mg/kg. This data is <br /> sufficient to satisfy the lead sampling required for this site and should be documented as <br /> such in the PEA. <br /> 8. Section 13.2, page 13-3 <br /> The second paragraph of this section is contradictory in that it states that the results of the <br /> samples collected and the associated risk and hazard assessment does not indicate the <br /> need for further action on the site, while recommending further testing and possible <br /> removal and replacement of soil impacted by total petroleum hydrocarbons (TPH) <br /> detected above 1000 mg/kg. <br /> DTSC concurs with the recommendation to remove the TPH-impacted soil and <br /> understands the 1000 mg/kg TPH represents a cleanup goal based on the consultant's <br /> application of the California Regional Water Quality Control Board's Guidance for <br /> Petroleum-Impacted Sites: Soil Screening Levels, May 1996. Document why the removal <br /> of TPH is considered to be a "precautionary measure" (ie, aesthetic and odiferous impacts <br /> of TPH with respect to potential students, faculty and staff that will occupy the site). The <br /> justification for removal of TPH-impacted soil above 1000 mg/kg, should be well <br /> documented. <br /> 9. Appendix A <br /> All boring logs should state the name and license number for the California Registered <br /> Professional (e.g., a Registered Geologist (RG) or a licensed Civil Engineer/Professional <br /> Engineer) that reviewed them for accuracy, or the logs should be stamped by the <br /> California Registered Professional reviewer themselves. Modify the boring logs included <br /> in this PEA accordingly. <br /> Lockeford Elementary School, Lodi Unified School District, Draft PEA Comments <br />
