Parreira Almond Prooming Company N-1082706, N-1337-1-6,2-7,6-1, 7-0, B-0 of the application. This test data suggests that NOx emissions of 22 ppmv at 0%02, equivalent to 6.2 ppmv at 15%02, may be achievable. However,that test was conducted using a California Energy Commission (CEC) protocol that calculated pollutant mission factors based on a weighted average of 20%for emissions at 100% load, 50%for emissions at 75% bad, and 30% for emissions at 50% load. In contrast, the District ac oepts 5-mode testing using ISO 8178 procedures that assign weights of 5%to emissions at 100% load, 25%to emissions at 75% load, 30%to emissions at 50% load, 30%to emissions at 25% load, and 10%to emissions at 10% load for calculating emission limitations. it is worth noting that the YSAQMD source test results show average N%concentrations of 16.2 ppmv at 100% load, 11.4 ppmv at 75% load, and 44.2 ppmv at 50% load (all at 0% 02). This means that the CEC protocol assigns a 50%weighting factor to the cleanest of the three operational modes tested, in contrast to ISO 8178 which assigns the highest weighting factor (30%)to emissions at 500A and 25% load, where NO,,emissions are much greater. Moreover, conversations with YSAQMD personnel Indicate that the NOx emission limitation for this engine (once a permit is Issued)will be 9 ppmvd at 15% 02.Therefore,the YSAQMD test report cannot be considered a basis for determining that a NOz emission limit lower than 9 ppmvd at 15% 02 is achieved in practice at this time. Almond Processing (N-1337-1-6. 2-7. 6-1): Projects N-1040455, N-1081230, and N-1072060 included air-to-doth ratio calculations, and concluded that the ratio was appropriate for the design and use of those baghouses. Since Mere is no change in the almond processing operations,the earlier air-to-cloth ratio calculations remain valid. No further discussion is required. VII. General Calculations A.
