St.Joachim's Parish • • Page 3 of 3 <br /> Our Project Number: E07091A <br /> May 23, 2007 <br /> 3.2 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 Liqui-Nox solution or equivalent between borings, changing latex <br /> protective gloves after each sample, and recording sample information on chain-of-custody <br /> forms. <br /> 3.3 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) by 8015M/8021B, total petroleum hydrocarbons as diesel <br /> (TPH-d) by 8015M, and benzene, toluene, ethylbenzene, and toluene (BTEX), oxygenates, and <br /> lead scavengers by 80268. <br /> 4.0 PROPOSED TIME SCHEDULE FOR WORK <br /> Assuming approval of this workplan, we propose to perform the work between May 29 and June <br /> 1, 2007. Standard laboratory turn-around is five business days. We will forward the results of <br /> the work to the EHD within one week of receipt of the laboratory results. <br /> 5.0 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 /> 6.0 LIMITATIONS <br /> The proposed scope of work for the Phase II has been tailored to address the specific issue of <br /> soil impacts from the former leaking underground storage tank site adjacent to the property. If <br /> additional investigation is requested, such investigation will be performed as a separate scope <br /> of work. <br /> 7.0 SIGNATURES OF ENVIRONMENTAL PROFESSIONALS <br /> This workplan has been prepared under the supervision and direction of the undersigned. <br /> NEIL a ANDERSON&ASSOCIATES, INC.
