stakeholders. The utility of this model will be demonstrated through an observationalexperiment. Key attributes and preferences will be elicited from a population ofstakeholders in a Web environment. After eliciting these preferences, the participantswill then engage in a dynamic modeling exercise in which they are able to interactivelyexplore land use decisions considering the complexities of urban dynamics; thenumerous tradeoffs, risks, and uncertainties; the resource constraints; and so on. Wecall this model DMASE (for Dynamic/Multi-Attribute/Spatially-Explicit). Preferencesover the key attributes will then be elicited again. We hypothesize that the keyattributes and preferences will change appreciably based upon interaction with theDMASE model. Additionally, the model can be modified in an iterative fashion tocapture the decision context and preferences of the participants in a more meaningfulway. This work will lead to a decision support tool that will allow stakeholders anddecision-makers in declining cities to make more informed decisions about changesin the complex urban environment.P.39 Greene CW, Goeden HM, Dady JM, Ross M, Shubat PJ; christopher.greene@state.mn.usMinnesota Department of HealthIDENTIFYING AND EVALUATING DRINKING WATER CONTAMI-NANTS OF EMERGING CONCERN: A STATE PERSPECTIVEContaminants of Emerging Concern (CECs), substances for which humanhealth risks are not well understood (whether due to new toxicity or exposure information,or a lack of information on risks), pose a challenge to public health agenciesworking to ensure the safety of drinking water. The Minnesota Department ofHealth (MDH) has completed its first two years of work under a new initiative toproactively identify drinking water CECs, evaluate the potential for human exposure,and develop health-based guidance values to assist risk managers in making publichealth decisions. During that time, MDH has devised a multi-stage process forscreening chemicals based on both toxicological and exposure-based criteria. MDHelicited CEC nominations from other state and federal agencies, from the public, andfrom within the department. Nominated chemicals represented a variety of chemicalclasses, including pesticides, industrial chemicals, pharmaceuticals, and personal careproducts. All nominated chemicals meeting a broadly defined definition of CEC underwenta screening level review for toxicity (potency, severity, endocrine activity) andexposure potential (occurrence, persistence/fate, patterns of use.) Chemicals identifiedas high priority underwent a higher-level toxicological evaluation, including thedevelopment of guidance values where feasible, and further characterization of thepotential for human exposure. Development of the program in its first two years hasbeen characterized by (1) an emphasis on process development; (2) thorough analysisof toxicological data for the development of guidance values; (3) comparison ofknown or potential exposures to guidance values; (4) input from external workgroupson chemical assessment and communication with the public; and (5) research intonew methodologies suitable to the unique requirements of CECs. Project outcomeswill be presented for ten chemicals, including triclosan, DEET, TCEP, acetaminophen,and carbamazepine.P.105 Grespin ME, Le MH, Panko JM; mgrespin@chemrisk.comChemRiskSAFETY DATA SHEET ALTERATION DURING ALIGNMENT WITHTHE GLOBALLY HARMONIZED SYSTEM OF CLASSIFICATION(GHS) AND IMPLICATIONS FOR CHEMICAL MANUFACTURERS,SUPPLIERS, AND DISTRIBUTORSThe Occupational Safety and Health Administration (OSHA) has issued a noticeof proposed rulemaking to align its current Hazard Communication Standard(HCS) with provisions set forth by the United Nations’ Globally Harmonized Systemof Classification (GHS). Among the changes expected to be made by OSHA whenit adopts the GHS guidelines, safety data sheets (SDSs) will be developed or existingOSHA material safety data sheets (MSDSs) will be modified to reflect the explicitenvironmental, physical, and health hazard criteria set by the GHS. This presentationwill discuss in detail the changes to SDSs resulting from adoption of the GHS.Whereas the current performance-based HCS requires inclusion only of broad categoricalinformation, the specification-based GHS SDS will require that 16 specificheadings be included in each chemical SDS, with each section providing a more detaileddescription of its relevant components than is currently required by OSHA.Covered under the new 16 heading format will include topics related to product andhazard identification, chemical composition and reactivity, regulatory and transportationinformation, and extensive health and safety guidelines. Implementation of theserequirements is expected to decrease incidence of worker illness and injury comparedto the current HCS, but may pose challenges to manufacturers, suppliers, or distributorsattempting to comply with the new GHS SDS provisions.W3-I.2 Grieshop AP, Marshall JD, Kandlikar M; agrieshop@ncsu.eduNorth Carolina State University; University of Minnesota; University of British ColumbiaHEALTH AND CLIMATE BENEFITS OF COOKSTOVE REPLACE-MENT OPTIONSThe health and climate impacts of available household cooking options in developingcountries vary sharply. Here, we develop and apply a simple, extensible analyticalframework to compare stove options across multiple impacts (health; climate)and quantify the potential co-benefits from upgraded fuel and stove combinations.Health impacts are quantified via estimated personal PM intake and a recently proposedlog-linear intake-response relationship applicable to PM concentrations wellabove typical urban levels. Climate impacts are estimated using the global warmingcommitment on a 100 year time horizon, which gives a conservative (low) estimate107
