Under Category 1 Smoke, which burning is allowed?

Under Category 1 Smoke, which burning is allowed?

• A. No burning allowed except crop stubble and grass fields
• B. All burning is allowed
• C. Nighttime burning only
• D. Burning only in urban areas

Answer: (D)

Category 1 Smoke denotes the lowest-risk smoke category, where burning is allowed only under conditions that minimize public exposure and can be closely managed. Urban areas provide the infrastructure, monitoring, and regulatory controls that help keep smoke concentrations within acceptable limits, so burning is permitted there when using this category. This contrasts with broader permissions (all burning), rural-only restrictions, or nighttime-only rules, which do not align with the controlled, low-risk intent of Category 1 Smoke.
