CCA is used in pole treatment but that is about it these days, a lot of treatment plantsnhave switched to ACQ (ammonium copper quadrate if I remember correctly) for everything else, without the arsenic in it it is a bit more EPA friendly

All pine poles sitting in timber yards are typically CCA treated, but also your standard pine lumbar for framing is commonly available, but more places down here in Vic seam to be swapping to LOSP for environmental reasons and perhaps cost. Prefinished products such as external cladding and fascia are typically LOSP.
