Under CFR 1529, registration is required for projects exceeding how much area?

• A. Over 1000 square feet
• B. Over 100 square feet
• C. Over 10 square feet
• D. Over 50 square feet

Answer: (B)

Registration requirements are tied to a specific project size to balance regulatory oversight with practicality. When a project’s affected area goes beyond a set limit, the regulation kicks in to ensure proper review and oversight.

For this item, that threshold is over 100 square feet. That means any project whose footprint or total new/altered area exceeds 100 square feet must be registered. If the area is 100 square feet or less, registration under this trigger wouldn’t apply; once you exceed 100 square feet, registration is triggered.

This explains why the correct answer is the one stating “over 100 square feet.” The other options describe different size thresholds, which would either miss mid-size projects or impose registration for very small ones, not aligning with the regulation’s intended applicability.
