What is NOT a control measure for unpaved parking and storage areas?

• A. Paving the area
• B. Applying water for visible moisture
• C. Limiting vehicle trips to 15 per day
• D. Applying a suitable dust suppressant

Answer: (C)

Controlling dust in unpaved parking and storage areas is essential for minimizing air pollution and ensuring compliance with regulations. The measures typically implemented to manage dust include paving the area, which effectively eliminates dust generation; applying water to maintain visible moisture, which helps keep dust particles bound together; and using dust suppressants that chemically stabilize the surface to reduce particulate emissions.

Limiting vehicle trips, while it may seem like it could reduce dust emissions, does not directly address the source of dust generation in these areas. This is more of a traffic management strategy rather than a dust control measure. Hence, while reducing vehicle trips might contribute to lower dust levels indirectly, it is not a proactive control strategy like the other options provided, which directly aim to mitigate dust generation.
