RE: Project DUK-HV1101 Client Project: J11100180
Dear Mr. Perkins, On October 11, 2011, Brooks Rand Labs (BRL) received two (2) flue gas desulfurization (FGD) wastewater samples and two (2) corresponding blank samples. Samples were logged-in for total mercury (Hg) analysis. All samples were received, prepared, analyzed, and stored according to BRL SOPs and EPA methodology. The results were blank-corrected as described in the calculations section of the applicable SOP(s) and may be evaluated using adjusted reporting limits to account for sample aliquot size. Please refer to the Sample Results page for sample-specific detection limits and other details. All data was reported without qualification and all associated quality 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. Please feel free to contact me if you have any questions regarding this report.
Sincerely,

Tiffany Stilwater Project Manager tiffany@brooksran.comProject ID: DUK-HV1101

### Definition of Data Qualifiers

(Effective 9/23/09) 

### Laboratory Accreditation BRL is accredited by the National Environmental Laboratory Accreditation Program (NELAP) through the State of Florida Department of Health, Bureau of Laboratories (E87982) and is certified to perform many environmental analyses. BRL is also certified by many other states to perform environmental analyses. For a current list of our accreditations /certifications, please visit our website at <http://www.brooksrand.com/default.asp?contentID=586>. Results reported relate only to the samples listed in the report.

### Common Abbreviations

These qualifiers are based on those previously utilized by Brooks Rand, Ltd., those found in the EPA SOW ILM03.0, Exhibit B, Section III, pg. B-18, and the USEPA Laboratory Data Validation Functional Guidelines for Evaluating Inorganic Analyses; USEPA; July 2002. These supersede all previous qualifiers ever employed by BRL. Detected by the instrument, the result is > the MDL but ≤ the MRL. Result is reported and considered an estimate. B E An estimated value due to the presence of interferences. A full explanation is presented in the narrative. H Holding time and/or preservation requirements not met. Result is estimated. J Estimated value. A full explanation is presented in the narrative. J-M Duplicate precision (RPD) for associated QC sample was not within acceptance criteria. Result is estimated. J-N Spike recovery for associated QC sample was not within acceptance criteria. Result is estimated. M Duplicate precision (RPD) was not within acceptance criteria. Result is estimated. N Spike recovery was not within acceptance criteria. Result is estimated. R Rejected, unusable value. A full explanation is presented in the narrative. U Result is ≤ the MDL or client requested reporting limit (CRRL). Result reported as the MDL or CRRL. X Result is not BLK-corrected and is within 10x the absolute value of the highest detectable BLK in the batch. Result is estimated. 

### Field Quality Control Samples Please be notified that certain EPA methods require the collection of field quality control samples of an appropriate type and frequency; failure to do so is considered a deviation from some methods and for compliance purposes should only be done with the approval of regulatory authorities. Please see the specific EPA methods for details regarding required field quality control samples.

Jay Perkins Duke Energy Analytical Laboratory Mail Code MGO3A2 (Building 7405) 13339 Hagers Ferry Rd. Huntersville, NC 28078 (704) 875-5 245 Project: HAPS/MACT Testing Belews Creek (LIMS # J11100 1 80 )

Dear Mr. Perkins, Attached is the report associated with four (4 ) aqueous samples submitted for selenium speciation analysis on October 10 , 2011. The samples were received on October 11, 2011 in a sealed cooler at-0. 4 ° C. Selenium speciation analysis was performed via ion chromatography inductively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS). Any issues associated with the analysis are addressed in the following report. If you have any questions, please feel free to contact me at your convenience.
Sincerely,

Ben Wozniak Project Manager Applied Speciation and Consulting, LLC

## 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: HAPS/MACT Testing Belews Creek (LIMS # J11100180 )

October 1 8 , 2011

1. Sample Reception Four (4 ) aqueous samples in 125mL HDPE bottles (provided by Applied Speciation and Consulting) were submitted for selenium speciation analysi s on October 10 , 2011 . The samples were received on October 11 , 2011 in a sealed container at -0. 4 °C. The samples were received in a laminar flow clean hood void of trace metals contamination and ultra-violet radiation. Upon reception, the samples were designated discrete sample identifiers. An aliquot of each sample was filtered (0.45μm) and these filtrates were 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 dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS).

2. Sample Preparation All sample preparation is performed in laminar flow clean hoods known to be free from trace me tals 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-DRC

- 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 the samples may shift the equilibrium of the system resulting in changes in speciation ratios.

3. Sample Analysis All sample analysis 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 corrected to 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-DRC

- MS All samples for selenium speciation analysis were analyzed by ion chromatography inductively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS) on October 1 7 , 2011 . An aliquot of each sample is injected 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 (DRC) containing a specific reactive 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 these 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.
