Records are required to remain onsite during the construction period for a minimum of ___.

• A. 1 Year
• B. 2 Years
• C. 3 Years
• D. 5 Years

Answer: (C)

Keeping records on the site for the duration of construction is essential so that actions taken to prevent pollution—like implementing and updating BMPs, keeping inspection logs, and detailing any corrective measures—are documented and readily available for review. The minimum retention period is three years, which matches typical permit requirements and provides enough time for inspectors to verify ongoing compliance during the project. Shorter periods (such as one or two years) may not cover all inspections or potential post-construction inquiries, while five years goes beyond the minimum needed for this context.
