| Action | Dioxin source | Discharge estimate (% of total) |
Administrative responsibility |
Fiscal cost (central government) |
Implementation and enforcement cost (regional council) | Compliance cost (owner) |
|---|---|---|---|---|---|---|
| Ban on discharge | Landfill fires | 39 | MfE - preparation of information Local government / waste management industry / MfE - distribute, inform and educate | $5,000 | None. Already a prohibited activity within regional air plans. | None |
| Domestic waste burning | 11 | MfE - preparation of information Local government / waste management industry / MfE - distribute, inform and educate | $15,000 | $10,000 per year per council (less in urban areas). Costs will diminish with time as becomes accepted practice. $25,000 to revise air plans (where necessary). | Small additional cost for landfill charges, or for kerbside collection. Higher costs in rural areas. | |
| Copper wire burning | Unknown | MfE - preparation of information Local government / metallurgical industry / MfE - distribute, inform and educate | $5,000 | $5,000 per year per council. None if already a prohibited activity within some air plans. | None | |
| Limit on discharge | Medical waste incineration | 6 | Regional council - implementation and enforcement | None | $20,000 per existing consent reviewed. Cost savings for consents for new incinerators. | Technology costs for existing plant upgrades. $20,000 monitoring costs per facility per year. |
| Hazardous waste incineration | < 0.1 | Regional council - implementation and enforcement | None | $20,000 per existing consent reviewed. Cost savings for consents for new incinerators. | No technology costs; New Zealand's only incinerator already meets discharge limit. $20,000 monitoring costs per facility per year. | |
| Sewage sludge incineration | < 0.1 | Regional council - implementation and enforcement | None | $20,000 per existing consent reviewed. Cost savings for consents for new incinerators | No technology costs; one facility already required to meet discharge limit. $20,000 monitoring costs per facility per year. | |
| Municipal waste incineration | No municipal waste incinerator at present | Regional council - implementation and enforcement | None | None. Any incinerator will be new. NES will provide cost savings for new consents. | None. Any incinerator will be new. $40,000 monitoring costs per incinerator for the first year of operation, then $20,000 per year thereafter. | |
| Co-incineration in boilers [activity believed to occur on an ad hoc basis, but no definitive data available] | MfE - preparation of information Central and local government / industry sectors - distribute, inform and educate Regional council - implementation and enforcement | $10,000 | $15,000 per council to identify sources (boilers) where waste is co-incinerated. | Upgrade costs for any boiler that co-incinerates waste, plus $20,000 annual monitoring costs, OR (more likely) increased costs for waste disposal to landfill. | ||
| Monitor and research | Industrial fuel combustion (contaminated wood waste) | 3 | MfE: prepare information; design contaminated wood combustion air discharge monitoring programme in liaison with regional council and industry | $150,000 for data collection programme | Data collection programme | Data collection programme |
| Non-ferrous metal processing | 5 | MfE: prepare information; design foundry air discharge monitoring programme in liaison with regional council and industry | $150,000 for data collection programme | Data collection programme | Data collection programme | |
| Accidental fires | 7 | Central government: report on chlorinated materials in buildings and available alternatives | $50,000 | None | None | |
| Education | Domestic fuel burning | 16 | MfE with other government agencies and industry | $10,000 | None | None |
| Crematoria | 0.7 | MfE / MoH / sector agencies (e.g. funeral directors association) - guideline for crematoria operation. | $5,000 | None | None | |
| Do nothing | Industrial fuel combustion (coal, virgin wood, gas and used oil) | 10 | None | None | None | |
| Vehicle fuel combustion | 2 | None | None | None | ||
| Iron and steel manufacture | 0.4 | None | None | None | ||
| Minor miscellaneous sources | < 0.2 | None | None | None |
