Therefore, it is possible that the excavation was not <br /> conducted, or was conducted without prior approval by or notification to the Fire <br /> Chief. <br /> ' The remedial methods proposed in the Public Works Department letter pose <br /> potential concerns to the environmental condition of the property if they were <br /> carried out. The letter indicates that the soil contamination should be remediated <br /> by transport to an approved disposal area or "spread on the parcel in a method <br /> approved by the Fire Chief'. It further states, "The contaminated area shall be <br /> flushed with water to effectively purge the area of flammable vapors". Although <br /> these remedial methods were accepted practice at the time the letter was written <br /> in 1979, spreading of contaminated soil on a site in this manner is no longer <br /> accepted practice and could result in low levels of gasoline contamination in the <br /> soil. Further, flushing a contaminated site with water could create a potential for <br /> groundwater contamination of the underlying aquifer. <br /> The reported on-site soil contamination is not further documented in the Fire <br /> Department file, nor is it noted in the EHS file or other sources reviewed for this <br /> report. <br /> 17 <br />
