Subject | New Error in Emission Inventory (Table 1 and Table 2 disagree) |
Comment | The previous appendix B Table 2 on Line 3 "Hard with Add-On" showed the computation of the average source test value used in Table 1 of Appendix B above it. The calculation included results from seven tested facilities. The values were: As shown previously Test 1 0.00045 Test 2 0.00011 Test 3 0.001 Test 4 0.00034 Test 5 0.00063 Test 6 0.0002875 Test 7 0.0013 Average 0.000588214 Now, I don't know if the facility source test values you used above are correct or not but I do know math and the math appears to be a correct computation of the average of the values shown. In your now corrected emission inventory put out this morning, your team is using a value of 0.0000588214 as the source test value for hard chrome. I know that you know that 0.000588214 is a magnitude of 10 times greater than the 0.0000588214. So, what changed? Your team has not included a revised Table 2 with the data release from this morning. Therefore the 0.0000588214 is an unsupported value since it does not correspond to the yet to be corrected Table 2 of Appendix B. The official record supporting a hex chrome emission rule contains this critical 10X uncorrected error which is a building block of the current emissions of the industry. I recommend CARB introduce a quality assurance function. Those of us who are in the aviation safety business (until 2039) have found value in having a second set of eyes inspect work before it goes out. |
