State departments of transportation (DOTs) face new and state and federal regulations to reduce pollution in their stormwater discharges. This document provides information presented and discussed at the American Association of State Highway and Transportation Officials (AASHTO) National Stormwater Meeting held in June 2012 Raleigh, North Carolina. The theme of the meeting was “Connecting the DOTs” and provided state DOTs from across the country on stormwater regulations and on municipal stormwater conveyance and discharger.
This white paper discusses U.S. Environmental Protection Agency (U.S. EPA or EPA) stormwater updates, National Pollutant Discharge Elimination System (NPDES) permitting trends and new permit activities, information about DOT audits conducted by the states or U.S. EPA, stormwater asset management programs, contemporary post-construction stormwater controls, effectively focused construction stormwater management, and using a watershed approach to stormwater management.
This White Paper contains definitions, discussion on importance to DOTs, case studies from DOTs, future implications, considerations for moving forward, and key contacts and references for each of the key topics presented at the meeting. This document highlights information for practitioners across multiple functional areas within a DOT organizational structure.
