2111 ill <br /> x <br /> P� Harding Lawson Associates <br /> �s <br /> Chemical oxidation - This treatment process involves <br /> � adding hydrogen peroxide and a catalyst to excavated soils with <br /> �. detectable amounts of hydrocarbons. The hydrogen. peroxide in the <br /> presence of the catalyst oxidizes the hydrocarbons in the soil to <br /> produce carbon dioxide and water. The carbon dioxide would be <br /> released to the atmosphere and the water disposed of. Success- <br /> fully treated soils could be hauled off-site to a Class III land- <br /> fill. A pilot study would be required to determine a specific <br /> V.i ` ` treatmentrotocol and evaluate <br /> P by-products. <br /> This is a. relatively new technology that has been <br /> demonstrated at only a small number of sites. It is currently <br /> Y.. <br /> ,, being evaluated by regulatory agencies. A permit would be t <br /> .' required by the SJAPCD and possibly by the RWQCB. <br /> Because the technology required is still very new and <br /> generally not accepted, this alternative will not be further <br /> fy_ considered. <br /> ' :yr + <br /> incineration - Incineration involves subjecting exca I <br /> i <br /> vated soils to temperatures of 1,50o degrees. Fahrenheit in a <br /> rotary kiln, This is an established technology that has been <br /> ,t _ <br /> demonstrated highly effective in treating :hydrocarbons. A test <br /> _ - -burn- would be required to-demonstrate-the effectiveness-and effi- <br /> 4 ciency of the process at the Grant Line Road site. A permit. <br /> would be re ' <br /> quired from the SA.`rCD. <br /> fig <br /> While the technology is established and this process is . <br /> I currently being tested at several locations, incineration is not <br /> generally accepted by regulatory agencies. Historically, it .has <br /> 17 <br />
