From page 5...
... To construct and maintain highway infrastructure systems, DOTs and their associated contractors and consultants perform various tasks that typically involve earthwork operations at and around a project site, which can create stormwater, erosion, and sedimentation runoff issues, thereby potentially impacting receiving waters. Disturbed areas occur when vegetation, rocks, pavement, and other protective ground covers are removed during construction, thereby exposing the underlying soil, which is susceptible to erosion and sedimentladen runoff.
From page 6...
... Based on the objectives, the following areas were considered for data collection: • Current practices, approaches, and processes used by state DOTs to manage, monitor, track, and record information for proper stormwater management during construction • Types of BMPs and control measures used on DOT highway projects that are designed, installed, maintained, and inspected during construction • Formal and informal tools, guidelines, and training that DOTs have in place for executing stormwater management according to specifications and permit requirements • Information about the development and execution of the SWPPP for construction Synthesis Approach The literature review provided information about the current state of the practice for construc tion stormwater management, as well as the Clean Water Act (CWA) , permits, BMPs, control measures, and inspections.
