Question

1. how does the epa recommend handling sediment control during construction? source: https://www.epa.gov/npdes/stormwater-discharges-construction-activities student response:

Explanation:

To answer this, we refer to the EPA's guidelines for construction stormwater (from the provided source). The EPA recommends using Best Management Practices (BMPs) for sediment control during construction. These include:

1. Erosion Prevention Measures: Such as stabilizing disturbed soil with vegetation (e.g., seeding, mulching), using erosion control blankets, or installing silt fences around construction perimeters to prevent soil from being washed away.
2. Sediment Control Measures: Like using sediment basins or traps to capture runoff and allow sediment to settle, implementing sediment barriers (e.g., silt curtains in water bodies), and properly managing construction site runoff to direct it through sediment - reducing systems.
3. Site Planning: Minimizing disturbed areas, phasing construction to limit exposed soil time, and directing stormwater away from disturbed sites.

These practices aim to reduce the transport of sediment into water bodies, complying with the National Pollutant Discharge Elimination System (NPDES) requirements for construction activities.

Answer:

The EPA recommends using Best Management Practices (BMPs) like erosion prevention (e.g., vegetation, erosion blankets), sediment control (e.g., sediment basins, silt fences), and strategic site planning to handle sediment control during construction.
