Under the GP, a discharger may adjust the total acreage covered when which condition applies?

• A. A portion of the site is complete and/or ownership is transferred or new acreage added.
• B. Rainfall erosivity factor increases the site size automatically.
• C. The NOI is amended to reflect new acreage.
• D. The site is relocated to a new location.

Answer: (A)

The key idea is that the General Permit coverage is tied to the actual area being disturbed under the permit. If part of the site is finished, the remaining area that’s still under construction may be smaller, so you adjust the total acreage covered to match the current scope. Similarly, if ownership changes or you add new land, expanding the disturbed area, you update the coverage to reflect the new footprint. This keeps the NOI and the stormwater management plan aligned with what is actually regulated and reported. Rainfall erosivity doesn’t automatically change the permitted acreage, and relocating the site usually means a new permit instead of a simple acreage adjustment. Amending the NOI can implement a change after the boundary is updated, but the trigger for adjusting acreage is the change in the site boundary itself—partial completion, ownership transfer, or added acreage.
