Which two actions will help to minimize dust from stockpiles of soil?

Seeding the stockpile helps to minimize dust from soil stockpiles by promoting vegetation growth. Planting grass or other types of vegetation can stabilize the soil, reducing erosion and preventing particles from becoming airborne. The roots of the plants bind the soil together, which not only helps control dust but also can enhance soil health over time.

Covering the stockpile with a tarp is also an effective method to reduce dust, as it directly prevents wind from displacing soil particles. Similarly, damping down the materials with water can mitigate dust generation by adding weight to the particles and keeping them settled. Removing the stockpile entirely is a more drastic measure that may not always be necessary, and it doesn’t provide a long-term solution for managing dust if other stockpiles are present.

Thus, while seeding is beneficial, incorporating one or more of the other actions can provide complementary benefits for controlling dust emissions effectively.
