1 your logo here WasteMINZ Mid-Year Roundup Wellington

2 your logo here WasteMINZ Mid-Year Roundup Wellington Objectives define waste types intended for disposal define classes of landfill based on waste types provide a consistent approach to landfill siting, design, operations and monitoring make good practice recommendations on key technical requirements for siting, design, operations and monitoring of landfills based on landfill class.

3 your logo here WasteMINZ Mid-Year Roundup Wellington Land Disposal Technical Guidelines Revise CAE Landfill Guidelines (2000) Guide to the Management of Cleanfills Three major changes Landfill classification Good practice design Waste acceptance criteria

4 your logo here WasteMINZ Mid-Year Roundup Wellington Disposal to land means the final deposit of fill and/or waste materials into or onto land set apart for that purpose (landfill) Disposal to land does not include: earthworks operations farm dumps offal holes

5 your logo here WasteMINZ Mid-Year Roundup Wellington Waste definitions Cleanfill (revised) Managed/Controlled fill (new) Construction and Demolition (C&D) Waste (new) Household Waste (new) Industrial Waste Municipal Solid Waste Hazardous Waste

6 your logo here WasteMINZ Mid-Year Roundup Wellington Cleanfill Material that when discharged to the environment will not have a detectable effect relative to the background and comprising virgin excavated natural materials (VENM) such as clay, soil and rock that are free of: (list of exclusions)…

7 your logo here WasteMINZ Mid-Year Roundup Wellington Managed/Controlled Fill Fill material that is predominantly cleanfill, but may contain specified inert materials, such as concrete or brick and soils with concentrations of selected chemical contaminants that are greater than local background soil concentrations, but with specified maximum total concentrations

8 your logo here WasteMINZ Mid-Year Roundup Wellington Construction and Demolition Waste Waste generated from the construction, renovation, repair, and demolition of structures such as residential and commercial buildings, roads, and bridges. The composition of C&D waste varies for these different activities and structures. Overall, C&D waste is composed mainly of wood products, asphalt, plasterboard, and masonry

9 your logo here WasteMINZ Mid-Year Roundup Wellington Landfill Classes Class 4 (Cleanfill) Class 3 (Managed/Controlled Fill) Class 2 (C&D Landfill or Industrial Waste Landfill) (lined) Class 1 (MSW Landfill or Industrial Waste Landfill - Class A) (lined)

10 your logo here WasteMINZ Mid-Year Roundup Wellington Guidelines reflect current situation where “cleanfills” range from site accepting only VENM to sites accepting quantities of C&D waste or contaminated soils Recognize that different wastes require sites with different levels of environmental protection Already have lined C&D sites

11 your logo here WasteMINZ Mid-Year Roundup Wellington Key Design Revisions Clay liner and leachate collection for Class 2 landfills (C&D landfills and some industrial waste landfills) Composite liner required for Class 1 landfills

13 your logo here WasteMINZ Mid-Year Roundup Wellington Waste Acceptance Criteria Waste types suitable for each landfill class Contaminant limits Total inorganic and organic limits for Class 4 and Class 3 landfills TCLP limits for Class 2 and Class 1 landfills Want feedback on draft limits

14 your logo here WasteMINZ Mid-Year Roundup Wellington Class Common Name Waste DescriptionIncidental MaterialsWaste Acceptance Criteria 4Cleanfill Maximum incidental inert manufactured materials (e.g. concrete, brick, tiles) to be no more than 5% by volume per load; Maximum incidental or attached biodegradable materials (e.g. vegetation) to be no more than 2% by volume per load. Based on maximum total concentration limits derived from the regional background, and limited organic compounds. 3 Managed/ Controlled Fill Cleanfill Controlled/ Managed Fill Maximum incidental or attached biodebradable materials (e.g. vegetation) to be no more than 2% by volume per load. Based on maximum total concentration limits and limited organic compounds 2 Construction and Demolition Landfiill – Lined Cleanfill Controlled/ Managed Fill C&D Waste Inert Industrial Waste Maximum incidental or attached biodebradable materials (e.g. vegetation) to be no more than 5% by volume per load. Based on USEPA TCLP limits. 1MSW Landfill Cleanfill Controlled/ Managed Fill C&D Waste Municipal Solid Waste Household Waste Commercial Waste Industrial Waste Treated Hazardous Waste Based on USEPA TCLP limits.
