An optimal allocation of asset management resources is difficult, giventhe breadth of the national asset portfolio, and the diversity of projects, goals andneeds between and within the organization’s business lines. This presentation introducesan asset management model that improves the traditional asset managementapproach considering the non-monetizable impacts, high-risk factors, and cognitivebiases that can hamper the decision-making process for resource allocation acrossmultiple business lines. The risk-based model evaluates the exogenous and endogenousfactors that can adversely impact — directly or indirectly — aspects or componentsof the asset types. The characterization and evaluation of critical events andprocesses (climatological and anthropological), of construction materials, of assetmonitoring, and inter- and intra-correlation of assets among business lines have beenconsidered as criteria of each business line-specific MCDA model. The criteria forthe overall portfolio MCDA-based model are the value to the nation, the economicvalue, the safety and security, the environment impact, and the sustainability of eachasset that are broad fundamental objectives. The portfolio optimization that selectsthe most important asset-types among business lines is performed by linear optimizationconstrained to the available resources. The model is flexible to consider differentlife cycle stages of asset-types, thus also the construction of new assets may bepotentially modeled. A case-study is presented for three business lines: bridges, dams,and recreational facilities. It is envisioned that this type of formal asset managementtool can greatly enhance USACE’s ability to innovate and explore strategic optionsthat represent potential value-enhancing alternatives to the status quo.M4-E.4 Van Doren JM, Kleinmeier D, Ma Y, Blodgett R, Westerman A, ZiobroGC, Muckenfuss M, Gill V, Hammack T, Parish M, Neil KP, Mettee S, Nsofor O,Gieraltowski L; jane.vandoren@fda.hhs.govFood and Drug Administration, Centers for Disease Control and PreventionSURVEILLANCE SAMPLING AT IMPORT: CHARACTERIZING RISKConsumption of Salmonella-contaminated food is one of the leading causes offoodborne illness in the United States. The 2008-2009 Salmonella Rissen outbreakattributed to contaminated white pepper and the 2009-2010 Salmonella Montevideo186and Senftenberg outbreaks attributed to contaminated black and red pepper highlightedthe potential for spices to contribute to foodborne illnesses. Since spicesare primarily supplied by way of imports to the United States, regulatory guidancesuch as import alerts and FDA surveillance sampling are tools used by the Food andDrug Administration to prevent contaminated spices from reaching the consumer.This talk will focus on surveillance sampling of FDA regulated imported productsas a means of characterizing the prevalence and level of contamination in importedspices. Data presented will explore the prevalence of Salmonella in spices as a functionof spice type, form and country of origin. Enumeration data reveal typical levelsand distribution of Salmonella in spices. The impact of different sampling strategieson the efficacy of Salmonella detection in spices will also be explored.P.24 Villarraga Farfán EJ; julieth_villarraga@hotmail.comUniversidad de los AndesPRELIMINARY ASSESSMENT OF THE CARBON FOOTPRINT INTHE CHEMICAL INDUSTRY IN THE FIELD OF BASIC CHEMISTRYGHG emissions are part of the environmental risks that affect the Earth today.The emission of these gases produces adverse effects on living organisms and theenvironment. Among the most notable effects is the alteration of the hydrologicalcycle, as having a higher temperature in the Earth’s surface increases the evaporationof water, causing as latitude, increased rainfall or drought periods. The first step toreduce GHG emissions is to quantify it. To measure the amount emitted, organizationsuse the carbon registry protocols, such as the GHG Protocol. I performed thestudy and quantification of GHG emissions in a Colombian chemical industry leaderin salt and chlorine production. For quantification of GHG emissions, environmentalinput and output analysis method was used, including emissions from stationary pointsources (boilers, reactor and energy consumption) and mobile sources (lifts, transportof raw materials and products) which resulted a carbon footprint of 341175 tons ofCO2 eq. Quantifying the carbon footprint for the organization can establish practicesto mitigate GHG emissions, reducing environmental impact and atmospheric effectsassociated with them. Emissions reduction is focused on identifying the main sourcesof emissions, because from this industries can define best practices in a productionprocess, such as the reduction in product delivery times, programs for the maintenanceor renewal of equipment, among others. The first possibility of reducing thecarbon footprint comes from chemical industry, increasing productivity, ie, emits thesame amount with more manufacturing. Thus, reducing the carbon footprint is aninitiative to encourage programs to increase production and efficiency of available resourcesin the organization. Also, is important to quantify the carbon footprint fromdeveloping countries, because the majority of emissions come from energy consumption,land use and industrial processes.
