Research for the AASHTO Standing Committee on the Environment. Task 85. Nutrient (Nitrogen/Phosphorous) Management and Source Control

As the U.S. Environmental Protection Agency (U.S. EPA) continues to press for development of numeric nutrient criteria for state waters and incorporation of nutrient Total Maximum Daily Loads (TMDLs) into National Pollutant Discharge Elimination System (NPDES) permits, it has become increasingly important for NPDES permit holders to have effective, flexible, and low-cost implementation alternatives for nutrient management. This project addressed the growing need for a better understanding of nutrient cycling, fate and transport, and removal mechanisms to improve the control of nutrient sources and runoff concentrations from department of transportation (DOT) facilities. The final report provides DOTs with an understanding of highway nutrient contributions and how they can be cost-effectively managed, if required, via best management practices (BMPs)
