Projected Emissions from BPXA Survey Sources Sample Clauses

Projected Emissions from BPXA Survey Sources. An inventory of projected emissions was prepared that reflects the operation of the R/V Thunder research vessel. As there would be no baseline of emissions associated with the no- action alternative, the projected emissions should be considered the total net emission increase caused by the Proposed Action. The projected emission inventory was prepared using the BOEM Form 0138. The form provides emission factors established by the EPA using EPA-approved methodologies to calculate projected emissions. The projected emission inventory includes an evaluation of the following pollutants:  CO;  NOX, where emissions of NOX are assumed to be made up entirely of NO2;  SOX, where emissions of SOX are assumed to be made up entirely of SO2;  Particulate matter (where emissions of PM are assumed to be made up entirely of PM10);  Volatile organic compounds (VOC); and  Carbon dioxide (CO2). Although a criteria pollutant, an assessment of ozone emissions was not included in the analysis. This is because ozone is not emitted directly by a source; rather ozone is formed through the secondary photochemical reaction between emissions of the precursor pollutants, NOx and volatile organic compounds (VOC), and sunlight. As such, an inventory of NOx and VOC emissions is provided and serves as an indicator of potential ozone development in the Noticed Activities area. While not a criteria pollutant, CO2 is considered a greenhouse gas that contributes to global climate change, and is included in the inventory. Diesel fuel contains no lead, a criteria pollutant; thus, the analysis did not include an inventory of lead emissions. Emissions from diesel engines were calculated using the standard EPA method of applying the output power (horsepower) to the emission factors, which are expressed as pounds per horsepower-hour (lb/hp-hr), and applying the number of total operating hours. The emission factors are summarized in Table C-2. The emission rates allow the quantity of each pollutant to be calculated based on the operating power of each engines. The BPXA Plan of Operations identify the survey vessel will by the R/V Thunder or a similar vessel. An image of the R/V Thunder is show in Figure C-2. Figure C-2. Research Vessel R/V Thunder.
