"LDEQ also requested the status of excess VOC emission from Tank 200-7 (EQT042) as part of the Heavy Oils Tank Cap (GRP0007). These emissions are subject to compliance Order AE-CN-08-0122A. Originally, MOUSA self-report to LDEQ that VOC emissions from this tank were estimated at 558.8 @/hr, exceeding the Maximum Allowable Emission Rate of 1.15 #/hr (with corresponding annual emission exceedances in tons per year). The suspected exceedances were based on MOUSA's calculation of emissions based on No. 6-Oil flash point data and Reid Vapor Pressure determinations, whereas the permitted emissions were based on published AP-42 emissions factors. MOUSA also self-reported that the No. 6 fuel oil may have exceeded the 1.5 psia trigger for controls at Tank 200-7. This VOC emission rate would result in an exceedance of the Heavy Oil Tanks Cap for 2008 (513.8 tpy actual vs. 7.2 tpy permitted)."
