### QUALIFIERS

Pace Project No.: Project: 92113409

J12030112

DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to changes in sample preparation, dilution of the sample aliquot, or moisture content. ND - Not Detected at or above adjusted reporting limit. J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. S - Surrogate 1,2-Diphenylhydrazine (8270 listed analyte) decomposes to Azobenzene. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Acid preservation may not be appropriate for 2-Chloroethylvinyl ether, Styrene, and Vinyl chloride. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. LABORATORIES Pace Analytical Services - Asheville PASI-A ANALYTE QUALIFIERS

RE: Project DUK-HV1201 Client Project: J12030112 Dear Mr. Perkins, On March 7, 2012, Brooks Rand Labs (BRL) received three (3) wastewater samples and three (3) corresponding field blanks. 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. Aside from concentration qualifiers, 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@brooksrand.com

Dear Mr. Perkins, Attached is the report associated with four (4) aqueous samples submitted for selenium speciation analysis on March 6 , 2012

.The samples were received in a sealed cooler at-0. 5 ° C on March 7 , 2012

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

Russell Gerads Vice President 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: Allen HAPS/MACT (Wastewater) (LIMS # J1203011 2)

March 14 , 2012

1. Sample Reception Four (4) aqueous samples in125mL HDPE bottles (provided by Applied Speciation and Consulting) were submitted for selenium speciation analysi s on March6 , 2012. The samples were received on March 7 , 201 2 in a sealed container at -0. 5 ° C. The samples were received in a laminar flow clean hood,void of trace metals contamination and ultra-violet radiation, and was designated a discrete sample identifier. An aliquot of each sample was filtered (0.45μm) and each filtrate w asstored in a secure, monitored cryofreezer (maintained at a temperature of -80o

## 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 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 correctedto account for any operational biases associated with the analytical platform. Prior to sample analysis, all calibration curves are verified using second source standards 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 asanalyzed by ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC -MS) on March 12, 2012. An aliquot 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 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 hydrogen 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 this sample 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
