Is there a charge to dispose of a small amount of scrap wood?

If the wood has never been painted stained or treated, it can be disposed of as clean wood ($11 minimum for loads under 500 pounds). If it has been treated or is mixed with other debris it can be disposed of as garbage ($20 minimum for loads under 360 pounds).

Minimum load is $20 for garbage. Clean and green: yard waste and wood that is not painted, pressure, treated, not many nails, etc is real cheap.

Yes but if it is clean wood it's much cheaper than their standard garbage minimum charge
