Burn Permits and Chip Piles: What Happens to the Wood in Ashland City

Two Rulebooks, Depending on Which Side of the City Line You Are On

Inside the town limits, open burning of vegetation is governed by the municipal code, which requires a permit for burning trees, leaves and natural untreated wood products, sets a ten-foot clearance around the fire and expects somebody present with water or a means of putting it out. It is a permitted activity, not a free-for-all, and not something to start on a Saturday morning because the pile is annoying you.

Outside the limits, on an unincorporated county lot, the state's forestry burning permit season is the one to know about — running through the colder half of the year, roughly mid-October to mid-May, when a permit is needed to burn leaves and brush in most Tennessee counties.

Either way, the paperwork is free or nearly free and takes minutes. What costs money is a fire department turnout to a pile nobody registered.

Treated Wood Is a Different Thing Entirely

The permission covers natural, untreated wood. It does not cover the fence panels that came off to get the machine in, the pressure-treated deck boards stacked beside the brush, or the pallet somebody left.

This matters more on a stump job than it sounds, because the pile that accumulates in a back yard during a removal is rarely pure brush. Old landscape timbers, a rotten arbour, a length of vinyl fence and a roll of woven wire from a hedgerow all end up in the same heap, and burning most of that is both illegal and a genuinely bad idea to stand near.

Sort the pile before you light it, or skip burning and have it hauled. On a town lot with neighbours forty feet away, hauling is usually the better neighbour policy anyway.

Grindings Are Not Brush, and Burning Them Fails

People assume the spoil pile from a grind can go on the same fire. It cannot, and trying is how a back yard ends up with something smouldering for three days.

Grindings are not chips. They are a mixture of shredded wood, bark and a substantial fraction of soil, sitting wet and packed. That mixture does not carry flame; it dries at the surface, smoulders underneath, and keeps producing smoke long after anybody has stopped supervising it. Fire departments in river-bottom towns hate them for exactly that reason.

There is a second reason not to try. Grind spoil is close to half soil by volume, so most of what you are attempting to burn is dirt, and what you have after two days of smoke is the same pile, slightly darker. Nothing has gone anywhere.

Burn the brush if you have the permit and the space. The grind spoil needs one of the other three answers.

The Three Realistic Ends for a Grind Pile

Backfill and tamp. Most of the spoil goes straight back into the void it came out of, in layers, compacted as it goes. On an average stump that absorbs the bulk of it and costs nothing.

Spread the surplus. Two or three inches deep in a bed or along a fencerow, well away from stems and well away from any drainage line, and it is gone into the soil in a couple of seasons. This works out toward Chapmansboro and Kingston Springs where there is somewhere to put it, and rarely on a fifth-acre town lot.

Haul it. The paid option, the right one on small lots, and effectively the only one on ground inside a mapped flood zone, where a mound left above grade stops being a landscaping question and becomes a fill question. Decide which of the three you want before the machine starts, because moving a pile twice is the one avoidable cost in this whole job.
