What is the minimum area of disturbed surface that requires a Dust Control Coordinator to be on-site?

• A. 1 acre
• B. 2 acres
• C. 5 acres
• D. 10 acres

Answer: (C)

The minimum area of disturbed surface that requires a Dust Control Coordinator to be on-site is indeed 5 acres. This requirement is set to ensure that adequate measures are in place to manage and mitigate the potential for dust generation, which can pose health risks and environmental concerns if not properly controlled.

A Dust Control Coordinator is essential for larger projects, as they oversee the implementation of dust control plans and ensure compliance with regulations. The threshold of 5 acres signifies a significant level of activity that could generate substantial dust, necessitating dedicated oversight. In areas smaller than this, the potential impact is considered manageable without the need for a dedicated coordinator. Therefore, projects disturbing 5 acres or more must have a designated individual to facilitate effective dust management strategies and maintain operational oversight to minimize air quality issues.
