CCA is relatively inert once dried, so pose little risk on installed poles and crossarms (including sawdust and chips) so follow EEA Guide as per Bill’s answer – however the biggest risk is that when burned the CCA additives concentrate in the ash and burnt residue. All of our burnt poles are disposed of at approved hazardous waste disposal facilities.

if you are searching the Web NZ, Australia, and Scandinavia are the only major users of CCA treatment so research from those counties will be more substantive.
