Revisions to add/reduce disturbed acreage must be filed electronically within how many days?

• A. 15 days
• B. 60 days
• C. 90 days
• D. 30 days

Answer: (D)

When the amount of land being disturbed changes, the stormwater pollution prevention plan must be updated to match the actual activity. This revised plan, reflecting the new disturbed acreage, has to be filed electronically with the regulatory authority within a 30‑day window. The 30‑day timeline helps ensure the plan’s controls are appropriate for the current project, keeps permit requirements up to date, and supports timely oversight of erosion and sediment controls. Filing earlier is acceptable and encouraged, while waiting longer than 30 days risks noncompliance because the plan would not reflect the active disturbance area.
