What is the purpose of a Stormwater Pollution Prevention Plan (SWPPP) in industrial facilities?

• A. To prevent pollution of stormwater by identifying potential runoff sources, implementing controls, and monitoring effectiveness.
• B. To organize employee lunches and break times.
• C. To document soil erosion only.
• D. To measure indoor air quality.

Answer: (A)

The plan is about preventing stormwater pollution from industrial activity by proactively identifying where runoff could pick up pollutants, putting in place controls to keep pollutants from leaving the site, and checking that those controls actually work. A stormwater pollution prevention plan lays out where pollutants could originate on-site (such as fueling areas, vehicle maintenance, chemical storage, and waste handling), the best management practices to reduce those pollutants (like good housekeeping, spill prevention, secondary containment, and sedimentation/erosion controls), and a plan to inspect and measure the effectiveness of those controls over time. This documentation helps ensure compliance with stormwater permits and protects local water quality.

The other options don’t fit: organizing meals has no relation to pollution prevention; documenting soil erosion only misses the broader pollution sources and controls; measuring indoor air quality is about air, not stormwater.
