RE: Project DUK

- HV1 201 Client P roject : J13010060 Dear Mr. Perkins, O n January 8, 2013 , Brooks Rand Labs ( BRL ) received three (3 ) wastewater samples and t hree (3 ) associated field blanks

. 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 to tal 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 of the 48 hour filtration requirement and the results were qualified H

. The results were blank

- corrected as described in the calculations section of the relevant SOP and may have been evaluated using reporting limits that have been adjusted to account for sample aliquot size. Please refer to the Sample Results page for samp le

- specific MDLs, MRLs, and other details. Aside from concentration qualifiers, all data was reported without further 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 us if you have any questions regarding this report. Sincerely,

Tiffany Stilwater Mi Sun Um Project Manager Data Manager tiffany@brooksrand.com misun@brooksrand.comProject ID: DUK-HV1201

### Common Abbreviations

These qualifiers are based on those previously utilized by Brooks Rand Labs, those found in the EPA SOW ILM03.0, Exhibit B, Section III, pg. B-18, and the USEPA Contract Laboratory Program National Functional Guidelines for Inorganic Superfund Data Review; USEPA; January 2010. 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.

## 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: Belews Creek (Flex Fuel) - WW (LIMS #J13010060)

January 15, 2013

1. Sample Reception Four (4 ) aqueous samples in125mL HDPE bottles (provided by Applied Speciation and Consulting) were submitted for selenium speciation analysis on January 7 , 2013

. The samples were received on January 8 , 201 3 in a sealed container at 1.0 °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 an 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 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 minimum 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 mass spectrometry (IC-ICP- CRC -MS) on January 9, 2013. Analiquot of eachsample 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 en ergy-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.

## If you have any questions or concerns regarding this report, please feel free to contact me.

Sincerely,

Russell Gerads Vice President Applied Speciation and Consulting, LLC
