Report No. <br /> A8524 and supporting documentation; completed Waste Classfication <br /> Form, May 23, 1985) indicates that the soil is contaminated with <br /> crude oil. It is the Department' s policy that soil contaminated with <br /> only crude oil may be managed as nonhazardous waste. <br /> However, the laboratory report shows that N-nitroso-di-k propylamine <br /> (NDPA) is also present at a concentration of 13.270 mg/ g- <br /> which <br /> is a common contaminant of the herbicide Trifluralin, has a reported <br /> acute oral LD50 of 480 mg/kg (Registry of Toxic Effects of <br /> Chemical Substances 1981-1982. NIOSH, June 1983 • Based on the <br /> information you submitted the calculated oral LD5 of the waste <br /> mixture is greater than 5000 mg/kg (Section 66696 c)) • Therefore, <br /> because of the low concentration of this contaminant and because the <br /> information you submitted indicates that crude oil is the only other <br /> contaminant, the soil may be managed as a nonhazardous waste. <br /> Since your client Renown Enterprises intends to establish a <br /> residential development on the property, the extent of contamination <br /> should be determined so that all the contaminated soil may be removed <br /> and properly disposed of. Disposal of the contaminated soil remains <br /> subject to the requirements of the Regional Water Quality Control <br /> Board. <br /> D csaly=g <br /> OCT 16 1985 <br /> ENVIROMENTAL HEALTH <br /> FERMIT/SERVICES <br />
