This poster describes a model for managing particulate matter (PM10) in the Las Vegas Valley, currently categorized as a serious non-attainment area for PM10 by the U.S. Environmental Protection Agency (EPA). The project client, the Department of Air Quality and Environmental Management (DAQEM), must provide a predictive model to the EPA as part of its plan to mitigate particulate emissions and wanted to utilize system dynamics for improving current methods. The model uses parts of Solomonís (1994) framework for regional air quality planning and management, including: sources of emissions, meteorology and transport, and removal processes. It is designed to meet the requirements of the EPA, identify policy levers for effectively reducing emissions, and allow for future addition of real-world management components such as the permitting system. This poster presents the structure of the working model, its results, and discusses its implications on managing PM10 in Las Vegas.
