08-03 — Best Practices in Addressing NPDES and Other Water Quality Issues in Highway System Management

Non-compliance with National Pollution Discharge Elimination System (NPDES) permits can impact project design, engineering and construction schedules and increase construction time and costs. Successful implementation and compliance with NPDES permits requires the appropriate transfer of information and accountability through multiple phases of project delivery.

Compliance with state and federal storm water regulations is complex, and DOTs must continually examine their approach to complying with the goals of improving water quality and reducing implementation costs. Additionally, DOT infrastructure improvements can be delayed if storm water requirements are not well integrated early into the planning and project delivery process. Participants in this scan investigated these issues, among others, surrounding the implementation of DOT storm water programs.
