Delaware's annual open burning ban has been in effect since May 1st and will remain active through September 30th. 

This seasonal measure is part of the state’s broader efforts to reduce ozone pollution during the warmer months, when air quality risks increase.

The Delaware Department of Natural Resources and Environmental Control (DNREC) reminds both residents and visitors that most outdoor burning is prohibited during this period. 

The ban is timed with the high-risk ozone season, as heat and longer daylight hours promote the formation of ground-level ozone.

Why the Ban Matters

Ground-level ozone forms when pollutants, including those from smoke, interact with sunlight. 

This pollutant not only harms the environment but can also pose significant health risks, particularly for children, older adults, and individuals with respiratory issues.

“The burning ban is critical for continuing to improve our air quality,” said Gerald Mood, an environmental scientist with DNREC’s Division of Air Quality. “As summer temperatures rise, and as we get longer daylight hours, the conditions which allow for the formation of ground-level ozone become more prevalent.”

What’s Allowed and What’s Not

While the ban restricts most forms of open burning, activities that are allowed include small fires for cooking, recreational use, or ceremonial purposes. These are examples of items that are still permitted. 

However, these too can be temporarily prohibited during Air Quality Action Days or under orders from the State Fire Marshal.

The ban specifically covers:

  • Agricultural and prescribed burns
  • Burning of yard debris like brush and tree limbs

It is illegal year-round to burn materials such as:

  • Leaves and grass
  • Trash, plastics, or tires
  • Construction and demolition waste

Safe Disposal Alternatives

DNREC recommends safer methods for handling yard waste, including:

  • Curbside collection
  • Drop-off locations
  • Mulching or composting
