This charged? Huh, https://zerowaste.dc.gov/what-goes-where agrees with you.

As long as I wasn't doing stone, brick, concrete, etc, I used to drop it off at Ft Totten. I used to just drive up, show my driver's license, say "construction debris", and put it in the pile.

I wonder if they'll resume accepting DIY construction debris when Ft Totten Transfer reopens over the summer. Perhaps they have capacity challenges without it?

Edit: the 2012 rules allow "trash, bulk items, recyclables and yard waste only." By the 2016 rules, they added that "yard waste does not include stumps; dirt; stones; rocks; broken concrete; broken pottery flower pots; roofing material; or construction and/or demolition materials". So, I'm surprised they let me in. I never tried to cover up that it was renovation stuff.
