You just have to find someone that sells cca treated lumber. It's still out there.

I can find it at marine lumber yards for seawalls, dock pilings etc. I think the EPA banned residential use of CCA treated lumber for residential use back in 2004 or maybe it was a voluntary ban on using for residential applications. Either way, the EPA friendly treatments suck!

EPA didn't want children chewing on lumber treated with arsenic in the playground.
