I <br /> 1 <br />( <br /> - Site Investigation Work Plan <br /> Nella Oil Station #21 , 40052 Highway 41 , Oakhurst, California <br /> 2.4 Potential Exposure Analysis <br /> TPH-G and BTEX constituents can create an exposure risk in certain circumstances through <br /> volatilization and vapor intrusion from shallow soils and groundwater. Benzene is generally the <br /> constituent of greatest concern in these circumstances; however, benzene was only identified <br /> from P-2 at 35 feet bgs at 30 . 7 ppb. The depth restriction and level of benzene present in the <br /> sample collected from the site are not significant enough to indicate a volatilization risk. <br /> 2 . 4 . 1 Sensitive Receptor Survey <br /> In accordance with Section 2654(b)(2) , Article 5, Chapter 16 , Division 3 , Title 23 of the <br /> California Code of Regulations , WRM will prep re a sensitive rector surveyfo> thesite - !, <br /> vicinity , within 2 ,000-feet of the site.
