Contractors working in Des Moines, Iowa must follow local and state air emission controls that apply to construction equipment, on-site processes, and dust or smoke sources.

• Identify sources: list equipment and materials that emit air contaminants.
• Check thresholds and trigger values on permit pages.
• Gather manufacturer specs and emission factor data for applications.
