    1. 1 Long-Term Containment and Hazard Classification of Solid Prescribed Industrial Wastes EPA Victorias role December 2003 Scott Maloney Manager - Waste Management

    2. 2 Agenda Background Introduction - EPAs role Summary of EPA PIW programs Draft documents open for comment Proposed hazard classification Proposed performance requirements Where to from here

    3. 3 Background Hazardous Waste Consultative Committee 1999/2000 Government response to HWCC, December 2000 No more hazardous waste to landfills IWMP to provide statutory backing Govt commitment to siting criteria, and to facilitation of the siting process (outside the scope of this process) Industrial Waste Management Policy (PIW), December 2000

    4. 4 EPAs Role Consult and finalise performance requirements for containment Explain PRs and works approval process to community and proponent Assess any works approvals/licence application to ensure a facility meets the requirements in the finalised documents Refer works approval to relevant agencies: DSE, DHS, WorkCover, Local Government Provide panel submission Participate in technical working groups

    5. 5 Overall program for hazardous waste Top 30 Program Waste Classifications by management option eg. - Contaminated soil - Grease interceptor trap waste Guidelines for hazard classification Category A, B and C wastes Safe management of residual waste Long-term containment facilities (Category B Waste) Best practice municipal landfill (Category C waste) Repository storage (options 2-3 years away)

    6. 6 Where do these wastes come from? PIW includes hazardous wastes and wastes that can have an adverse effect on amenity (eg. odour) PIW generally comes from the manufacture of goods and services we all use on a day to day basis Some common examples of PIW are from manufacturing of paint, chemicals, cars, plastics, metals and ceramics.

    7. 7 Draft documents Open for comment Draft Guidelines for Hazard Classification of Solid Prescribed Industrial Waste (Publication 922) Draft Performance Requirements for Long Term Containment Facilities (Publication 924) Also available: Draft Performance Requirements for Long Term Containment Facilities Explanatory Document (Publication 925)

    8. 8 Classifying Wastes by Hazard

    9. 9 Category Wastes Types - Examples Category A waste: A sludge from the bottom of a petroleum storage tank This type of waste would require treatment to remove or bind volatile chemicals and/or heavy metals prior to containment Category B waste: Solidified resins, lacquers or glue wastes These wastes are more stable than category A wastes and are able to be safely contained at an LTCF. Category C waste: A waste from the processing of food

    10. 10 Industry Types Likely To Contribute to LTCF

    11. 11 Developing the performance requirements Three stage consultation process Stage 1 initial request for comment October 2002 Stage 2 workshops and request for comments on containment systems April/May 2003 consideration of key questions and issues review of local and overseas developments Stage 3 feedback from Stage 2 considered workshops and request for comments on draft performance requirements October-December 2003

    12. 12 Performance requirements for containment Key objectives: No emissions to the maximum extent achievable; Design to safely contain waste for hundreds of years; A systems based approach which incorporates a high level of waste treatment, engineering, management and community assurance; and Requirements are outcome focused and do not specify what a facility looks like.

    13. 13 Performance requirements Section 3 Waste characteristics and treatment Wastes need to be accepted in accordance with EPAs hazard classification framework Some wastes may require immobilised waste classification from EPA Minimising moisture content of incoming waste.

    14. 14 Category A wastes wastes not suitable for containment Explosive wastes Flammable wastes Oxidising wastes Organic peroxides Infectious waste Corrosive wastes Radioactive wastes Waste liable to spontaneous combustion Waste, which in contact with water emit flammable gas Wastes that liberate toxic gases in contact with air or water Wastes that are capable of yielding another material which possesses any of these characteristics

    15. 15 Performance requirements Section 4 Containment design and construction Multiple barrier system. Eliminate emissions to the maximum extent achievable. Design and construct to provide a high level of protection for workers, community and the environment. Must design and construct to continue to contain the waste (designed for maximum practical longevity eg. hundreds of years) Multiple levels of redundancy.

    16. 16 Performance requirements Section 4 Containment design and construction The barrier system will : Control liquid and air emissions within and from the facility; Minimise the ingress of liquid (eg. rainwater/ groundwater); Detect emission or ingress that may move through the barrier;and Collect any emission or ingress detected within the barrier system.

    17. 17 Monitoring, inspection and maintenance

    18. 18 Minimising water ingress

    19. 19 Example of an overseas facility

    20. 20 Performance requirements Section 5 Containment operation and monitoring Environmental management system: operating procedures to eliminate emissions to the maximum extent achievable controls to ensure operating procedures are effective sampling, monitoring and reporting programs to verify controls and operating procedures Implement remedial actions where necessary Provide records and public information Regular performance audit

    21. 21 Monitoring, inspection and maintenance

    22. 22 Performance requirements Section 6 Post-closure management & responsibility Demonstration of effective containment via monitoring, inspection and maintenance. Establishing on-going post-closure ownership arrangements. Using financial assurance.

    23. 23 Performance requirements Section 7 Performance reporting & community Involving the broader and local community in all containment process stages: Design and construction Operation and monitoring; and Post-closure management. Regular public environmental public reporting of environmental performance

    24. 24 Where To From Here EPA is seeking your comments on the draft performance requirements for long-term containment. Performance requirements will be finalised and released with a response to comments document. EPA will use the performance requirements in assessing any future works approval and licence applications to establish a long-term containment facility.
