Synthesis of Information Related to Highway Practices. Topic 55-11. Construction Stormwater Program Management, Tracking, Reporting, and Compliance

State departments of transportation (DOTs) are responsible for maintaining state transportation systems while simultaneously maintaining environmental compliance. State DOT construction activities are required to comply with federal and state National Pollutant Discharge Elimination System (NPDES) Construction General Permit (CGP) requirements. The regulations require state DOTsto implement policies, procedures, and practicesto minimize offsite discharges of sedimentladen stormwater to protect downstream receiving water bodies during construction. To obtain permit coverage, regulated construction activities require the development, implementation, and maintenance of project specific Stormwater Pollution Prevention Plans (SWPPPs). The SWPPP provides construction stormwater-related management requirements and details on the installation and maintenance of structural and non-structural practices implemented during land disturbing activities. State DOTs nationwide are faced with CGP implementation challenges as they frequently find themselves needing to be flexible and creative with how to address, track, and report on construction stormwater compliance. There are a diverse range of platforms that provide a variety of tools that assist state DOTs with addressing construction stormwater compliance requirements. The objective of this synthesis is to document state DOT practices, tools, and approaches for managing compliance with state and federal construction stormwater permit requirements.
