Dear Mr. Perkins,

Attached is the report associated with three (3) aqueous samples and one associated blank submitted for selenium speciation analysis on October 7, 2010. The samples were received on October 8, 2010 in a sealed cooler at -0.3 o C. Selenium speciation analysis was performed via ion chromatography induc tively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS). Any an alytical issues associated with the analysis are addressed in the following report.

If you have any questions, please feel fr ee to contact me at your convenience.

Sincerely,

Russell Gerads Vice President Applied Speciation and Consulting, LLCApplied 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 Alternate Fuels Test Burn #1 - Se (LIMS # J10090178)

October 15, 2010

1. Sample Reception

Three (3) aqueous samples and one associated blank in 125mL HDPE bottles (provided by Applied Speciation and C onsulting) were submitted for selenium speciation analysis on October 7, 2010. The samples were received on October 8, 2010 in a sealed container at -0.3 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 stor ed 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 October 14, 2010. 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 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 notcontain methylseleninic acid or selenomethionine due to impurities in these standards which would bias the results for other selenium species.
