What can you burn and when?

Only leaves, woody debris or brush less than 5 inches in diameter can be burned.  Dimension lumber and untreated wood can also be burned.  No combustible domestic waste, treated wood, or composite materials may be burned. RSA-125N defines "combustible domestic waste" as, but not limited to, household trash, packaging materials, plastics, coated or laminated papers, rubber or treated wood, coated or treated cardboard, oily rags, and animal, vegetable, and kitchen waste.

For any open burning a written fire permit is required.  A category I fire may be kindled with a permit at any timewhether raining or not.  A category II and category III fire may only be kindled with a permit between the hours of 5:00 PM and 9:00 AM unless it is raining.  If it stops raining the fire must be extinguished.
