The Level 2 course, Design Principles for Erosion Prevention and Sediment Control for Construction Sites, is an advanced 2-day workshop designed for engineers and other professionals who have completed the prerequisite Level 1 course. TDEC through the current 2021 Construction Permit (CGP), requires that the SWPPP be prepared by individuals who have a working knowledge of erosion prevention and sediment controls, such as those who have successfully completed the Level 2 design principles course. Effective May 24, 2013, Site Assessment Inspections for quality assurance of installation, functionality and performance of erosion and sediment control practices at construction sites discharging into Impaired or Exceptional Tennessee Waters must be performed by individuals, who at minimum, have completed the Level 2 course. Professional Engineers and Landscape Architects, plan preparers and reviewers, project managers, and enforcement personnel from all levels of government involved with practice planning and design will find the course informative and useful. Instruction focuses on engineering technology needed to plan and design practices and controls for managing stormwater, preventing erosion and controlling sediment on construction sites. The Level 2 Design workshop provides the general tools needed for developing an acceptable, working SWPPP. Topics discussed in the course include: hydrologic methods for determining peak flows; principles of soil erosion, scouring and sediment transport processes, including practice examples for preventing erosion; and open channel principles and practices for designing a stable channel, including use and examples of riprap, blankets and matting, and vegetation; stormwater control requirements and design; sedimentation principles; and temporary sediment basin design requirements, and detailed examples. The Level 2 Design workshop provides a Certificate of Completion and sixteen (16) hours of Professional Development Hours (PDH) credit after attending both days and successfully completing the take-home exam.
