Analysis of Emissions from Power Plants and Other Large Combustion Sources March 2011Page 59July 31 – August 6, 2007; OTC 8-hr maximum ozone concentration of 118 ppbTable 9-4 provides the maximum 8-hour ozone concentration in each OTC State for eachday during the period. On Saturday, August 4, an 8-hour value of 118 ppb was recorded inMaryland. Nine of the MANE-VU+VA States exceeded the 75 ppb NAAQS on that day.Connecticut and New Jersey also recorded values above 100 ppb on July 9.Figure 9-4a shows the hourly NOx emissions in the entire MANE-VU+VA region duringthe period from units in the three classification bins. On a region-wide basis, the relativecontribution of emissions from units in the 15-50% and 50% bin. The large spikes in the hourly NOx emissions fromunits in the >50% bin are caused by a single unit – the Charles Poletti diesel oil-fired drybottomwall-fired boiler (ORIS 2491). On August 1, for example, NOx emissions in hour9 were reported as 1.2 tons in the CAMD database, spiked to 5.4 tons in hour 10, droppedback to 0.8 tons in hour 11, and spiked again to 5.3 tons in hour 12. It is not known ifthese spikes are real or if it is a data quality issue. Excluding these spikes, the pattern forthe >50% units is similar to the other episodes examined previously, there are times whenthe emissions from units in the 50%operating time bin.
