### The following describes any modifications and/or deviations to the applicable test

methods. If alternative methods were requested, see the attachments for documentation of request AND approval, including dates.

-This unit was not tested for Formaldehyde and was unnecessarily tested for VOST and Semi-VOST compounds. This was a result of the Weston and Southern Company interpretation of the Section 114 Letter and EPA’s lack of clarification until after the testing was completed. The data have been included based on discussions with EPA personnel.
-It is theorized that issues associated with the Speciated VOST analysis were due to high native source concentrations of Sulfur Dioxide (SO2). Specific issues are listed in the “General Comments” section of the

### Maxxam Analytics test report, Appendix D of the attached test report. Also, because of this effect several

compounds, including chloromethane, were affected and should be considered estimated values.
Maxxam Analytics comments: -The samples (VOST) exhibited extremely high levels of non-target compounds, mainly siloxanes, based on standards calibration criteria and response factors within the GC/MS, which caused the following to occur within the analytical sequence(s).
a)	The last internal standard (Bromofluorobenzene) failed for many of the samples b)	Following completion of an analytical run, we were unable to rid the system of these non-target analytes, thus inducing possible carryover into the subsequent analytical run(s). c)	We dismantled the desorber, rinsed, and baked it in a lab oven. Subsequent reinstallation of the hardware proved that residual amounts of the non-target analyte remained. d)	Repeated step c) again and finally were able to get to “clean” and ready. e)	Often difficult to meet the tuning criteria for the method and experienced huge losses of sensitivity on the system up to 2/3 of standard sensitivity. f)	Often could not get continuing calibrations to pass after running samples and it took hours of running calibrations to get the system to pass the continuing calibration criteria.
- Speciated VOST runs 1-3: levels of MeCl2 and other select target compounds were found in the sample tube blank and solvent blank. The run to run data appears to be related to a level of contamination.
-Speciated VOST tube pairs were evaluated separately for inter-run variability and the average of the selected tube pairs was used to for reporting purposes. This reporting procedure does not differ significantly from a total mass and total sample volume procedure.
-Semi-VOST runs 1-3: Bis (2-ethylheyl) phthalate, this compound is commonly found in plastics, it is not a common combustion product but an artifact of sample recovery or lab handling.
-Method 25A (THC)- Due to the very low levels found in the source gas a response time study would not be representative as written in the methods.
-Method 25A -The span gas values (low and mid) were not between method specified limits for percentage of achieved span concentration. Low span achieved 20%, method limits 25-35%. Mid span achieved 41%, method limits 45-55%.
-Method 25A -The test report and ERT have different values. The test report uses the approach set forth in the method, whereas, the ERT contains actual analyzer results. These results presented in the ERT contain values that show analyzer drift and include values below zero.
- Method 18 (Methane): Due to low methane concentrations in the source sample, a bag stability study was performed in lieu of a recovery study. Subsequently, the data presented in the test report have not been corrected for the 70-130% spike recovery procedure.
-Method 18 - the instrument response for each injection was not within 5% of mean response for the instrument.
-Method 18 - A mid range calibration standard wasn't analyzed after all samples were run.
