Where can you verify if an application site is in a nonattainment area?

The U.S. EPA Green Book is the correct source for verifying if an application site is in a nonattainment area. This resource provides a comprehensive overview of areas that do not meet the national ambient air quality standards for various pollutants. It is specifically designed to help individuals and organizations understand the air quality status of different regions across the United States.

By utilizing the U.S. EPA Green Book, professionals in the field can ensure compliance with environmental regulations as it offers the most up-to-date and accurate information regarding air quality standards and nonattainment zones. This ensures that fumigation practices do not inadvertently contribute to further air quality deterioration in regions where it is already a concern.

While local health departments and state agricultural offices may have relevant information, they might not provide the most definitive or current data specific to nonattainment areas. Online government resources could encompass a broader range of information, but the U.S. EPA Green Book is explicitly focused on air quality and nonattainment status, making it the most reliable and authoritative source for this specific inquiry.
