Upwind Data Separate from the sampling performed by Region IV personnel, upwind data were independently collected by APPCD personnel and equipment. These data were provided separately to Arcadis. Arcadis found that all the preliminary data manipulation had already been performed and that spectra already existed as individual absorbance files ready for AutoQuant ® . Because these data were collected on a different instrument and at a different spectral resolution, the method files and calibration spectra used for the samples were not appropriate to the upwind spectra. EPA also provided the correct method file and calibration spectra. C 5 Quantification and results processing were performed as described above for the 60 files generated on 2/ 14/ 00. Examination of the individual results revealed 2 sets of the 60 that had questionable results for one or more compounds. The errors associated with these concentrations were much higher than the other 58 for the same compound. USEPA personnel had made the same observations during calculation of this data set. These two samples were, therefore, eliminated after examining the original spectra and results from these two samples were not used in the calculation of average upwind concentrations.

The individual results from the upwind samples were used to calculate average concentrations and the standard deviation. These values were then used to calculate a detection limit for each compound based upon the typical equation:

Detection_ limit mean 3 * = +   where   is the standard deviation.

Arcadis used a slight deviation from the above equation in calculating a detection limit for SF6. As the Table 2 shows, both the average and the standard deviation for this compound are 0. For this compound only, Arcadis used the average error reported by AutoQuant ® in place of the standard deviation.

Table 2. Results for Upwind Data, including Estimated Detection Limits Results are in ppm Carbon Monoxide Methane Nitrous Oxide Sulfur Hexafluoride Average 0.264 1.795 0.301 0 Standard Deviation 0.155 0.031 0.004 0 Detection Limit 0.729 1.887 0.312 0.000241 Intercomparison Hardcopies of the results spreadsheets are being delivered with this memo/ report. Of these, spectra from 2/ 24/ 2000 were separately analyzed by Mantech; these results were supplied by the WAM. Arcadis results were compared point by point with the Mantech results. These comparisons are found in the four attached graphs. It can be stated that differences are minor to none and are within the AutoQuant ® reported errors. Trendlines were established for methane, carbon monoxide, nitrous oxide, and sulfur hexafluoride. These results are reported in Table 3. C 6 Table 3. Intercomparison Results Slope Intercept R2 Methane 0.9988 0.0057 1 Carbon monoxide 0.9735 0.0074 0.9986 Nitrous oxide 1.0064  0.0013 0.9965 Sulfur hexafluoride 1 0 1 These factors refer to Mantech results as the independent variable ( x) and Arcadis results as the dependent variable ( y).

The Mantech and Arcadis results may be considered identical for all practical purposes. Table C 1. HANST SCREENING METHOD + Sulfur Hexafluoride Upwind Data for the Chlor Alkali Testing Study.
