AECOMEnvironmentQuality Assurance Project Plan AddendumRemedial Investigation/Feasibility StudyPines Area of InvestigationSection:Revision:Date:Page:Section A1April 20141 of 2A.0 Project ManagementA.1IntroductionIn April 2004, the United States Environmental Protection Agency (USEPA) and the Respondents(Brown Inc., Ddalt Corp., Bulk Transport Corp., and Northern Indiana Public Service Company(NIPSCO)) signed an Administrative Order on Consent (AOC II) (Docket No. V-W-’04-C-784) toconduct a Remedial Investigation and Feasibility Study (RI/FS) at the Pines Area of Investigation,located in the environs of the Town of Pines, Indiana, as set forth in Exhibit I to II (AOC II, 2004).AOC II (Section VII. 22) and its attachment, the Statement of Work (SOW) (Task 8), require theRespondents to conduct a Feasibility Study (FS) as part of the RI/FS process. As documented in theFS (AECOM, 2014a), additional soil investigations will be conducted. A Supplemental SoilCharacterization (SSC) Work Plan (AECOM, 2014b) provides the details for conducting this work.This Quality Assurance Project Plan (QAPP) Addendum incorporates the RI/FS QAPP (AECOM,2005) by reference and was prepared to reflect the scope of work described in the SSC Work Plan,and is provided as Appendix B of the Work Plan.A.2Project ScheduleThe project schedule is presented in Section 6.0 of the Supplemental Soil Characterization Work Plan.A.3Distribution ListThe QAPP Addendum, and any subsequent revisions, will be distributed to the personnel shown onthe Distribution List that immediately follows the approval page.A.4Project/Task OrganizationThe lines of authority and communication specific to the Quality Assurance (QA) program for thisadditional soil investigation are presented in Figure A-1.A.5Problem Definition and BackgroundBackground and the objectives specific to the additional soil investigation are provided in Sections 1.1and 1.2, respectively, of the SSC Work Plan.A.6Project/Task DescriptionTo meet the objectives defined in the SSC Work Plan, three data collection tasks will be conducted:1. Gamma count rate and gamma dose rate surveys2. Coal combustion by-product (CCB) visual inspection confirmation sampling3. Soil sampling of selected properties for specific constituentsThe number of field and quality control (QC) samples that will be collected for each analyticalparameter is presented in Table A-1. A summary of analytical parameters by medium is presented inAOC II – Docket No. V-W-’04-C-784 – SSC WPApril 2014

Theseprocedures are described in Sections 3.2.1 and 3.2.2 of the SSC Work Plan. Standard operatingprocedures (SOPs) are included in Appendix C of the SSC Work Plan.B.2.2 Sampling ProceduresThe SOPs that will be utilized for CCB visual inspection confirmation sampling and private propertysoil sampling (Sections 3.3 and 3.4 of the SSC Work Plan, respectively) are provided in Appendix C ofthe SSC Work Plan.B.3Sample Handling and CustodyB.3.1 Sample Containers, Preservation, and Holding TimesA summary of sample container, preservation, and holding time requirements is presented in TableB-1.B.3.2 Sample LabelingLabeling of sample containers is described in Section 4.2.2.2 of the SSC Work Plan.B.4Analytical MethodsAnalyses will be performed by laboratories that have been utilized for previous investigations at thePines Area of Investigation and approved by USEPA. Chemical analyses of soil samples for metals(including hexavalent chromium), except total uranium will be performed by The ALS Group (ALS;formerly Columbia Analytical Services, Inc.) in Rochester, NY. Gamma spectroscopy analyses for theradioisotopes and inductively coupled plasma – mass spectroscopy (ICP-MS) for total uranium(calculated from U-235 and U-238) will be performed by General Engineering Laboratories, LLC(GEL) in Charleston, SC. Particulate matter analyses will be performed by RJ Lee Group (RJ Lee) inMonroeville, PA.AOC II – Docket No. V-W-’04-C-784 – SSC WPApril 2014
AECOMEnvironmentQuality Assurance Project Plan AddendumRemedial Investigation/Feasibility StudyPines Area of InvestigationSection:Revision:Date:Page:Section B1April 20142 of 3B.4.1 Laboratory Analytical ProceduresB.4.1.1 MetalsA list of the ALS and GEL SOPs for metals analyses is provided in Table B-2. The SOPs are includedin Attachment A.B.4.1.2 Particulate MatterThe particulate matter analysis by RJ Lee will consist of polarized light microscopy (PLM), X-raydiffraction (XRD), X-ray fluorescence (XRF), and loss on ignition (LOI). The PLM analysis will be usedto identify crystalline and non-crystalline glassy and organic phases in the sample and to identifyparticles with fly ash or bottom ash morphologies. The PLM analyses will be performed in generalaccordance to EPA 600/R‐93/116, Test Method for the Determination of Asbestos in Bulk BuildingMaterials. The SOPs for the particulate matter analysis are not included in Attachment A because RJLee considers them to be proprietary. The SOPs are available for review at the RJ Lee facility. Asummary of the procedures are presented below.The sample will be spread on a grid on one or more glass slides, and 400 random points on that gridare observed. Particles will be identified by the microscopist as either fly ash or bottom ash and theseparticles will be counted. If one particle of fly ash is counted in any of those 400 grid squares, thesample will be reported as containing 0.25% fly ash. If a single fly ash article is observed in the lightmicroscopy field, but it is not contained in any of the 400 grid squares randomly selected for counting,a result of “trace” will be reported, which quantitatively is 0.25% fly ash. The same method will applyto the bottom ash results.Particle Counting Interpretations Observations on a 400-point GridResultObservations on a 400-point GridNDNo particles observed within or outside of the grid 0.25%No particles observed within the grid, but particle(s) observed upon review of theentire slide0.25%1 particle observed within the grid0.5%2 particles observed0.75%31%41.5%62%8The XRD analysis will be used to identify the crystalline phases present in the samples and will beperformed in general accordance to ASTM D934, Standard Practices for Identification of CrystallineCompounds in Water-Formed Deposits by X-ray Diffraction. The LOI analysis (based on ASTMD7348, Standard Test Methods for Loss on Ignition (LOI) of Solid Combustion Residues) will be usedto determine the weight of percent organic and volatile constituents in the sample and to prepare theAOC II – Docket No. V-W-’04-C-784 – SSC WPApril 2014

XRF will be performed in general accordance to ASTM D4326, Standard Method for Analysisof Coal and Coal Ash by X-ray Fluorescence.B.4.1.3 RadionuclidesA list of the GEL SOPs is provided in Table B-2. The SOPs are included in Attachment A.For the radionuclides by gamma spectroscopy, GEL will dry and prep samples according to theirSOPs and seal samples in a 100 cc “tuna can” sample container for a minimum of 28-days prior toanalyses. The samples will be counted using the more sensitive detector (N-type) and will be countedfor a sufficient amount of time, to a maximum count time of 1000 minutes, in order to meet theminimum detectable concentration (MDC) requirements in Table A-4. The radionuclides that will bereported for the soil samples will be based on the gamma spectroscopy library that is provided inAttachment B.The following limits on sensitivity parameters will be applied for gamma spectroscopy analysis: Energy Tolerance: 1.5 kiloelectron volts (keV)Peak Sensitivity: 3.0Abundance Limit: 75%GEL will conduct a thorough review of 'Unidentified Peaks' and note such peaks with comments in thebatch narrative. Any nuclides identified in the 'Unidentified Peaks' report that are not already beingreported may be added to the library following approval by the AECOM project manager. For eachradionuclide in the gamma library, GEL will report the concentration along with its sample specificuncertainty for each sample as obtained during analysis even if the concentration is less than theMDC or is negative (Section 16.6 in MARLAP, 2004).USEPA plans to collect split samples for independent analysis. The specific procedures for sampleselection, collection, and shipment will be provided by USEPA and will be accommodated in the field.B.4.2 List of Project Target Constituents and Detection LimitsA listing of project target constituents and reporting limits (RLs) or MDCs for each analyte group listedin Table B-2 can be found in Tables A-3 (metals) and A-4 (radionuclides).B.5Quality ControlTable B-3 summarizes the QC for the analytical methods. Field QC will include field duplicates,equipment blanks, and matrix spike/matrix spike duplicate (MS/MSD) samples, as appropriate for theanalytical method. Table A-5 presents the limits for each field QC sample. Procedures andfrequencies will be consistent with those described in the RI/FS QAPP.AOC II – Docket No. V-W-’04-C-784 – SSC WPApril 2014
