Special Message

Tips to minimize open burning smoke impacts:

  • Burn between the hours of 11 am and 4 pm.
  • Limit burning when winds are over 12mph
  • Only burn materials that have dried out sufficiently
  • Ensure the fire has plenty of oxygen
  • Do not allow burn piles to smolder
  • Leaves and grass clippings should be taken to a landfill and not burned
  • Check with your local fire protection service to determine if a burn permit is required or if local or state restrictions prohibit burning in your area.
