National Action Plan for Addressing Dioxins in Australia

National Dioxins Program – National Action Plan for addressing dioxins in Australiamaximum contaminant level goal (non-enforceable, voluntary health goal) of zero and a maximumcontaminant level of 300 pg/L has been set.SoilUnder the EPA Superfund, an important aspect is the clean up of dioxin contaminated lands. Aroundthe country there are many Superfund sites which have successfully been cleaned up, however, toprevent further contamination of dioxins to land, the EPA has developed Hazardous WasteIdentification and Disposal Rules which identify and strictly limit the disposal options of wastecontaining dioxins.The US Public Health Service and the EPA have both issued a directive that 1000 ng/kg is theappropriate criterion to use for dioxins and furans in residential soil.WastesThe EPA proposed rules to restrict the use of dioxin-contaminated pulp and paper sludge andguidelines have been developed to limit the dioxin concentration to 31.9 pg/L.The EPA proposed regulations limiting the dioxin content of cement kiln dust from cement plants andsludge when these by-product materials are used as soil additives.In October 2003, the US EPA made the decision not to regulate dioxins in land-applied sewage sludgeas studies have shown that dioxins from this source do not pose a significant risk to human health orthe environment.OtherThe US EPA has set limits on the level of human exposure of dioxins at 0.006 pg/kg bodyweight perday.JapanThe Law Concerning Special Measures Against Dioxins (the Dioxins Law) came into force in January2000 to regulate the levels of dioxins in air, water and soil as well as emissions from smallincinerators. This law also stipulates basic standards for dioxins in soil. The Dioxins Law stipulatesthe standards for dioxins as:Ambient Air 0.6 pg-TEQ/m 3WaterSedimentSoilEffluentTolerable Daily Intake1 pg-TEQ/L150 pg-TEQ/g1,000 pg-TEQ/g10 pg-TEQ/L4 pg-TEQ/kg bw/dayEuropean UnionThe cornerstone of the EU environmental action is the Sixth Environment Action Program entitledEnvironment 2010: Our Future, Our Choice which has the priorities of:• tackling climate change and global warming41
