For a finished project, what must be done within 10 days to control dust?

• A. Pave or apply gravel to the site
• B. Install signage regarding the project
• C. Gather community feedback on dust
• D. Phase all work operations as per standards

Answer: (A)

The requirement to pave or apply gravel to the site within 10 days for dust control is rooted in the necessity to mitigate airborne particulate matter that can result from construction activities. Paving or using gravel effectively stabilizes the soil surface, reducing the likelihood of dust being generated by wind or movement within the site. This approach is a direct and immediate measure aimed at addressing dust emissions, facilitating compliance with air quality standards and ensuring a safer environment for surrounding communities.

While installing signage, gathering community feedback, or phasing work operations are important aspects of project management and community relations, they do not directly address the immediate need to control dust on the finished project site. Signage may inform about the project, community feedback could guide future practices, and phasing operations can optimize workflow, but none provide the tangible, rapid impact on dust management that applying paving or gravel does. Thus, focusing on physical solutions like paving is the most effective strategy for dust control following project completion.
