Reynolds Ranch APNs 050-10&-11 • Page 3 <br /> Our Project Number: LES 78 <br /> November 5, 2008 <br /> 4.2 Quality Assurance/Quality Control (QA/QC) Procedures <br /> Quality Assurance/Quality Control (QA/QC) procedures will be used to minimize the potential for <br /> contamination of soil samples. The QA/QC procedures may include the use of single-use <br /> sampling equipment, decontamination of drilling and sampling equipment by washing with a <br /> solution of potable water and Liquid-Nox solution or equivalent between borings, use of one <br /> duplicate sample per day, changing latex protective gloves after each sample, and recording <br /> sample information on chain-of-custody forms. <br /> 4.3 Soil Sample Laboratory Tests <br /> Soil samples will be transported to a California state certified analytical laboratory where the <br /> following Environmental Protection Agency (EPA) tests will be performed: total petroleum <br /> hydrocarbons as gasoline (TPH-g), oxygenates, benzene, toluene, ethyl benzene, and xylenes <br /> (BTEX) by 8015M/8260B, total extractable petroleum hydrocarbons as diesel (TPH-d) and motor <br /> oil (TPH-m.o.) by 8015M/8021B, and LUFT 5 Metals by 7000 series. <br /> 5.0 PROPOSED TIME SCHEDULE FOR WORK <br /> Assuming approval of this work-plan, we propose to perform the work between November 6 <br /> and November 12, 2008. Standard laboratory turn-around is five business days. We will <br /> forward the results of the work to the EHD within one week of receipt of the laboratory results. <br /> 6.0 REPORT PREPARATION <br /> A letter report will be prepared to present the analytical test results for the soil samples. The <br /> letter report will include laboratory test result sheets and chain-of-custody documentation. <br /> 7.0 LIMITATIONS <br /> The proposed scope of work for the soil borings has been tailored to address the specific issue <br /> of the former underground storage tank on the property. If additional investigation is <br /> requested, such investigation will be performed as a separate scope of work. <br /> 8.0 SIGNATURES OF ENVIRONMENTAL PROFESSIONALS <br /> This workplan has been prepared under the supervision and direction of the undersignAoFEs '/o <br /> ,y <br /> . <br /> mac <br /> NEIL O, ANDERSON&ASS 7E 4 �Q�i S.
