## 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 – FGD Alternative Fuels Test Burn #3 - Daily) (LIMS # J11030165)

March 21, 2011

1. Sample Reception Four (4) aqueous samples in 125mL HDPE bottles (provided by Applied Speciation and Consulting) were submitted for selenium speciation analysis on March 8, 2011. The samples were received on March 9, 2011 in a sealed container at -0.4 o 

## C. The samples were received in a lamina r flow clean hood void of trace metals contamination and ultra-violet radiat ion. 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 speciat ion analysis could be performed via ion chromatography inductive ly 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 metals contamination. All a pplied water for dilutions and sample preservatives are monitored for contamina tion 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 filt er (0.45μm) and inject ed directly into a sealed autosampler vial. No further sa mple 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 precluded by a minimum of a five-poi nt calibration curve spanning the entire concentrati on range of interest. Calibration curves are performed at the beginning of each analytical day. All calibration curves, associated with each species of interest, are sta ndardized by linear regression re sulting 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 ve rified using second source standards which are identified as initial calibration verification standards (ICV). Ongoing instrument performance is iden tified 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 Anal ysis 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 March 11, 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-tr ansfer 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 whic h 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 very well and no analytical issues were encountered. All quality control parameters associated with these samples were within acceptance limits.
The estimated method detection limits (eMDLs) for selen ite, selenate, and selenocyanate are generated from replicate analyses of the lowest standard in the calibration curve. Not all selenium speci es are present in preparation blanks; therefore, eMDL calculations based on preparat ion 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. The selenocyanate recoveries for the ma trix spike and matrix spike duplicates performed on the sample identified as Batch QC were below the established control limit of 75% (0.0%). The selenite recoveries for the matrix spike and matrix spike duplicate were 188.3% and 188.2%, respecti vely. The low selenocyanate and the elevated selenite recoveries are attributed to the sample matrix inducing oxidation of selenocyanate to selenite. The ambient sample concentrations support the oxidative nature of the samples since only oxidized se lenium species were present. The quality control discrepancies were a function of the sample matrix; therefore, no corrective action was required. If you have any questions or concerns regardi ng this report, please feel free to contact me. Sincerely,

Dear Mr. Perkins, O n March 9 , 2011 , Brooks Rand Labs ( BRL ) received three ( 3 ) flue gas desulfurization ( FGD ) waste water samples and three (3) field blanks (one from each related FGD sample site)

. All samples were logged

- in for total mercury (Hg) analysis and 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 a ll quality assurance criteria were satisfied. The analysis of the low calibration standard (1100161

- CAL1) produced an abnormal peak sh ape. The low calibration standard was re - analyzed as 1100161

- CAL6 and the re

- analysis was reported . No additional corrective action was required. 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.

### 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.
