### Program Comments: Please contact the Program Manager (Jason C Perkins) with any questions regarding this report. Data Flags & Calculations: Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results) under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have been qualified by Duke Energy to perform these analyses except where noted. Data Package: This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except in full, without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions. The order of individual sections within this report is as follows: Job Summary Report, Sample Identification, Technical Validation of Data Package, Analytical Laboratory Certificate of Analysis, Analytical Laboratory QC Reports, Sub-contracted Laboratory Results, Customer Specific Data Sheets, Reports & Documentation, Customer Database Entries, Test Case Narratives, Chain of Custody (COC) Certification: The Analytical Laboratory holds the following State Certifications : North Carolina (DENR) Certificate #248, South Carolina (DHEC) Laboratory ID # 99005.

Jay Perkins Duke Energy Analytical Laboratory Mail Code MGO3A2 (Building 7405) 13339 Hagers Ferry Rd. Huntersville, NC 28078 (704) 875-5 245 Project: Allen Shay/MillerCreek (LIMS #J12080131)

Dear Mr. Perkins, Attached is the report associated with four (4 ) aqueous samples submitted for selenium speciation analysis on August 7, 2012. The samples were received in a sealed cooler at-0.3 ° C on August 8, 2012

. Selenium speciation analysis was performed via ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC -MS).

## Applied Speciation and Consulting, LLC Report prepared for: Jay Perkins Duke Energy Analytical Laboratory Mail Code MGO3A2 (Building 7405) 13339 Hagers Ferry Rd. Huntersville, NC 28078 Project: Allen Shay/MillerCreek (LIMS #J12080131)

August 16, 2012

1. Sample Reception Four (4 ) aqueous samples in125mL HDPE bottles (provided by Applied Speciation and Consulting) were submitted for selenium speciation analysis on August 7, 2012. The samples were received on August 8, 201 2 in a sealed container at -0.3 ° C. The samples were received in a laminar flow clean hood, void of trace metals contamination and ultra-violet radiation, and were designated discrete sample identifiers. An aliquot of each sample was filtered (0.45μm) and each filtrate w as stored in a secure, monitored cryofreezer (maintained at a temperature of -80 o 

## C) until selenium speciation analysis could be performed via ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC -MS).

2. Sample Preparation All sample preparation is performed in laminar flow clean hoods known to be free from trace metals contamination. All applied water for dilutions and sample preservatives are monitored for contamination to account for any biases associated with the sample results. Selenium Speciation Analysis by IC-ICP-CRC-MS Prior to analysis, an aliquot of each sample was filtered with a syringe filter (0.45μm) and injected directly into a sealed autosampler vial. No further sample preparation was performed as any chemical alteration of a sample may shift the equilibrium of the system, resulting in changes in speciation ratios. 3. Sample Analysis All samp leanalysis is preceded by a minimum of a five-point calibration curve spanning the entire concentration range of interest. Calibration curves are performed at the beginning of each analytical day. All calibration curves, associated with each species of interest, are

## standardized by linear regression resulting in a response factor. All sample results are

instrument blank correctedto account for any operational biases associated with the analytical platform. Prior to sample analysis, all calibration curves are verified using second source standard s which are identified as initial calibration verification standards (ICV). Ongoing instrument performance is identified by the analysis of continuing calibration verification standards (CCV) and continuing calibration blanks (CCB) at a minimal interval of every ten analytical runs. Selenium Speciation Analysis by IC-ICP-CRC-MS Eachsample for selenium speciation analysis w as analyzed by ion chromatography inductively coupled plasma collision reaction cell ma ss spectrometry (IC-ICP- CRC -MS) on August 8 & August 9, 2012. An aliquot of eachsample isinjected onto an anion exchange column and mobilized by a basic (pH > 7) gradient. The eluting selenium species are then introduced into a radio frequency (RF) plasma where energy-transfer processes cause desolvation, atomization, and ionization. The ions are extracted from the plasma through a differentially-pumped vacuum interface and travel through a pressurized chamber ( CRC ) containing a reaction gas which preferentially reacts with interfering ions of the same target mass to charge ratios (m/z). A solid-state detector detects ions transmitted through the mass analyzer and the resulting current is processed by a data handling system. Retention times for each eluting species are compared to known standards for species identification.

4. Analytical Issues The overall analyses went well and no significant analytical issues were encountered. All quality control parameters associated with the samples were within acceptance limits. The estimated method detection limits (eMDLs) for selenite, selenate, and selenocyanate are generated from replicate analyses of the lowest standard in the calibration curve. Not all selenium species are present in preparation blanks; therefore, eMDL calculations based on preparation blanks are artificially biased low. The eMDL for methylseleninic acid and selenomethionine is calculated from the average eMDL of selenite, selenate, and selenocyanate. The calibration does not contain methylseleninic acid or selenomethionine due to impurities in these standards which would bias the results for other selenium species.

RE: Project DUK
- HV1 201 Client P roject : J12080131 Dear Mr. Perkins, O n August 8 , 2012, Brooks Rand Labs ( BRL ) received three(3 ) wastewater sample s and three (3) corresponding field blank s. An aliquot was removed from each sample bottle and filtered into a separate container designed for dissolved mercury (Hg) analysis. The sample volume from the original container was logged
- in for total Hg analysis

. All samples were received, prepared, analyzed, and stored according to BRL SOPs and EPA methodology. Data used for regulatory purposes has a 24 hour filtration holding time requirement. Non
regulatory purposed data has a 48 hour filtration holding time. The samples were received outside the 48 hour filtration requirement and are qualified H

. The results were blank
- corrected as described in the calculations section of the relevant SOP(s) and may have been evaluated using reporting limits that have been adj usted to account for sample aliquot size. Please refer to the Sample Results page for sample
- specific MDLs, MRLs, and other details. Instrument blank

– IBL1 was analyzed on a faulty purge vessel. The sample was then re
analyzed on good purge vessel, produced an acceptable result, and reported as

– IBL5. The original analyses of the low and high calibration standards were analyzed on the same faulty purge vessel as

– IBL1. Both samples were re
- analyzed and reported as

– CAL6 and

– CAL7. The original purge vessel was removed from service. The analysis of the first continuing calibration blank (
- CCB1) was elevated. This was likely attributed to carry
- over contamination from the analysis of

– CAL7 (10,000 pg of Hg). The purge vessel used for the analysis of

–CCB1 and

–CAL7 was checked and reported as

–CCB2, which yielded a very low result. All data wa s reported without qualification, aside from concentration qualifiers, and all associated q uality control sample results met the acceptance criteria. BRL, an accredited laboratory, certifies the reported results of all analyses for which BRL is NELAP accredited meet all NELAP requirements. For more details , see the Report Information page of the report.
