Corpus Christi is the sixth largest industrialized urban area in Texas。 It is currently in compliance with the U。S。 Environmental Protection Agency's (EPA) National Ambient Air Quality Standards (NAAQS) for ozone and other pollutants。 However， the Texas Commission on Environmental Quality (TCEQ) has classified Corpus Christi urban airshed (CCUA) as a near non-attainment area based on the 8-hour ozone standard。 The National Emission Inventory (NEI) for 2005 indicated point and non-road mobile emissions constituted 27% and 22%， respectively of the total anthropogenic NO_x emission within CCUA。 However， the largest and yet uncertain sub-categories of air emissions from non-road mobile sources in CCUA include ocean going vessels (OGVs) and barges。 Therefore， it became very important to study the impact of anthropogenic emissions from marine engines within the urban area。 The objective of the study was to develop a comprehensive emissions inventory of criteria and greenhouse gas (GHG) pollutants for the base year of 2008。 Emissions from marine engines was developed using EPA recommended and California Air Resource Basin (CARB) adopted methodologies based on unique activity profile， size of vessel， and engine characteristics of each vessel entering and leaving the Corpus Christi ship channel。 During 2008， OGV contributed approximately 1，427 tons of NO_x and 49 tons of VOC to the Corpus Christi urban emissions。 The maximum emissions from OGV occurred during hoteling， i。e。 48% of NO_x and 49% of VOC of the total marine engine emissions。 The study further evaluated the impact assessment of the quantified emission to the urban ozone levels using a photochemical model。
