Which two plans in the SWPPP must be approved?

• A. Erosion and sediment control plans and stormwater management plans must be approved.
• B. Erosion plan only
• C. Stormwater management plan only
• D. Sediment control plan only

Answer: (A)

Two plans in the SWPPP must be approved: the erosion and sediment control plan and the stormwater management plan. The erosion and sediment control plan focuses on preventing soil erosion and keeping sediment from leaving the site during construction, using practices like stabilization of exposed soil, sediment basins, silt fences, and proper sequencing of activities. The stormwater management plan addresses how stormwater will be managed on and after the project, detailing treatment measures, pollutant controls, maintenance schedules, inspections, and post-construction stabilization to meet water-quality requirements. Both plans are essential components of the SWPPP and require review and approval by the regulatory authority to ensure the project will control pollutants in stormwater throughout construction and after completion. If only one plan were approved, the site could still experience uncontrolled erosion or inadequate stormwater treatment, leading to runoff problems. The sediment control aspects alone would not guarantee proper post-construction stormwater management, and the stormwater plan alone would not ensure erosion controls are in place during earthwork.
