Brazil - updated soil contamination regulations
While Brazil has not changed its waste generator liability since adopting Law 6.938 in 1981, it has updated and altered requirements for generators. Most recently, the Brazilian National Council on the Environment (CONAMA) adopted CONAMA Resolution 420/2009, establishing guidelines and criteria for the management of contaminated sites. CONAMA Resolution provides for the creation of soil quality criteria, guidelines for the remediation of contaminated sites, and contaminated sites record-keeping at the local level. CONAMA Resolution 420/2009 requires facilities with potential to cause soil and groundwater contamination to have a monitoring program for soil and groundwater quality in place and to submit a conclusive environmental audit report on soil and groundwater quality to renew their environmental licenses or prior to their permanent closure.
