Research for the AASHTO Standing Committee on the Environment. Task 35. Water Quality Analyses for NEPA Documents: Selecting Appropriate Methodologies

<div><font size="3">The National Environmental Protection Agency (NEPA) requires that sponsors of transportation projects consider the impacts of those projects on water quality and water resources. There are numerous methodologies available to perform these analyses; however, there is little or no guidance on the appropriate method for a NEPA analysis versus other purposes. This study will review currently available water quality models / methodologies used for analyzing potential impacts of transportation projects, provide a description and assessment of each model/method and a determination of whether the model/method is out-dated or valid. If valid, the study will identify the type of project or level of analysis the model/method is best suited to as well as any limitations to the model's use.</font></div>
