i <br /> Working To Restore Nature <br /> test sequence is complete; 'and, 5) the APCD shall grant prior written approval. These <br /> requirements are discussed in the following paragraphs. j <br /> II <br /> The purpose of the operation!is to determine the feasibility and evaluate the effectiveness of the <br /> asphalt burner to remediate soil. The goal is to reduce concentrations of hydrocarbons in the <br /> soil to nondetectable levels so that the soil may be used as subbase for roadways and the risk <br /> of leaching hydrocarbons to groundwater is eliminated. <br /> The soil will be processed through the asphalt batch plant burner which operates at a;minimum <br /> temperature of 400 degrees Fahrenheit. It is expected that at this temperature hydrocarbons will <br /> be destroyed in the combustion process and the emission of air contaminants would be minimal <br /> _since�zjthere is only an estimated pounds of_total.petroleum;hydr_ocarbons as_diesel_and;0.12 <br /> total pounds of benzene, toluene," ethylbenzene, and xylenes in the soil. Samples will be <br /> collected from processed soil and submitted for laboratory analysis. If hydrocarbons are <br /> detected then the soil will be;reprocessed and tested until nondetectable levels are achieved. <br /> i <br /> RESNA will begin the proposed operations upon approval of the APCD and the other agencies <br /> involved. The length of operation is dependent upon the need to reprocess the soil. It is <br /> estimated that the operation will last a total of 30 days but will not exceed 180 days. Results <br /> of the operation will be submitted to the APCD within 60 days following completion as required. <br /> RESNA requests written approval of the APCD to continue with the operation discussed in this <br /> letter. If you require additional information please contact our office. <br /> Sincerely, <br /> RESNA Industries Inc. <br /> �.P.a�YtM.��J�krwt�y <br /> Jeanne Homsey, P.E. 00 <br /> CA?Registered-Civil�Enginee> 47410.. <br /> _. <br /> JH/gk <br /> cc: Bob Fourt, StanislausCounty DER <br /> Michael Johnson, RW�QCB <br /> Bill Keller, Western Stone Products <br /> Mary Meays, San Joaquin County PHS/EHD <br /> (LErrERSUr101293.FNL1 ,h <br /> i <br />
