Under Category 3 Smoke, dispersion being excellent allows what burn times?

• A. No burning allowed
• B. Only daytime burning
• C. Only nighttime burning
• D. All hours for daytime burning and nighttime burning

Answer: (D)

When smoke dispersal is excellent, the atmosphere mixes plumes quickly and evenly that ground-level smoke is kept low. This means there’s less risk of smoke impacts downwind, so burn timing isn’t constrained by smoke dispersion. In this case, you can schedule burns across all hours, including both daytime and nighttime, as long as other safety and weather factors are acceptable. The other options imply restrictions or prohibition that aren’t necessary with excellent dispersion.
