CCA has never been banned, it
CCA has never been banned, it was a voluntary effort by manufacturers to stop using it in response to public outcry regarding its use in boardwalks and children's play equipment. http://www.epa.gov/oppad001/reregistration/cca/ An easy way to ensure that your lumber wasn't treated with CCA is that most companies now use copper azole, which turns the lumber green (copper). If your lumber is green, it was not treated with CCA.
