Temporary erosion and sediment control measures MUST be removed within a MAXIMUM of how many days after the final site stabilization?

• A. 15 days
• B. 30 days
• C. 45 days
• D. 60 days

Answer: (B)

Once the site is stabilized and no further soil-disturbing activities are planned in that area, temporary erosion and sediment control measures should be removed within 30 days. These controls are installed to protect against sediment during active construction, but they’re not meant to stay in place indefinitely. After final stabilization—when the ground has attained adequate perennial vegetation or another approved stabilization method and the area is no longer at risk of significant erosion—the removal window gives enough time to finish cleanup and restore the site without leaving temporary devices in place longer than necessary. Choosing 15 days would be an insufficient period after stabilization to complete removal and cleanup. Choosing 45 or 60 days goes beyond the required maximum, potentially delaying the site’s return to a normal condition and increasing maintenance concerns.
