Best Practice : Risk Assessment Modeling
Based on its own concerns and those of the Southwest Marine, San Diego, and Puget Sound Naval Shipyards, the Applied Research Laboratory at the Pennsylvania State University (ARL Penn State) submitted a bid to the National Shipbuilding Research Program (NSRP). The bid’s purpose was to design a scientifically-based tool that shipyards could use for negotiating National Pollution Discharge Elimination System (NPDES) limits. This tool would assist the shipbuilding/repair industry with NPDES permits and compliance; standard settings; and risk management.
The ARL Penn State enlisted help from the National Steel and Shipbuilding Company (NASSCO) in San Diego, California and professors from the Pennsylvania State University. Together, the group identified current and future NPDES requirements for shipbuilding and repair facilities, and developed a computer model to predict shipyard flow; transport of contaminants; and an ecological, risk-calculator computer model.
The NPDES Risk Assessment Model consists of three, interlinked models that predict the dispersion of shipyard pollutants in a bay/estuary and the resulting environmental risk from the pollutants. Although currently based on the NASSCO and the San Diego Bay, this risk model can be adapted for use by any shipyard. The final document is available at: www.usashipbuilding.com. The document is titled: “A Shipyard Program for NPDES Compliance” (document number NSRP-0569).
