The following are recommended resource consent conditions for Class A landfills and Class B landfills.
Operational conditions
1. No liquid wastes shall be accepted for disposal. For waste to be considered non-liquid it must meet one of the following requirements:
- a solids content of at least 20% and liberate no free liquids when transported; or
- no free liquids when tested in accordance with the US EPA Paint Filter Liquids Test (US EPA Method 9095A 1996) and liberate no free liquids when transported.
2. Medical wastes shall only be accepted in accordance with NZS 4304:2002 "Healthcare Waste Management", or subsequent amendments.
3. Asbestos waste shall be accepted only in accordance with the Asbestos Regulations 1998, or subsequent amendments.
4. The following wastes are not acceptable for disposal at the landfill:
(i) waste marked with an asterisk on the NZ Waste List (L Code), with the following exceptions:
- solid wastes which, following testing using the US EPA Toxicity Characteristic Leaching Procedure (TCLP), result in leachable concentrations of contaminants less than the leachable concentration values listed in Table 1; or
- solid wastes which, following testing for total concentration, result in total concentration values less than the screening criteria listed in Table 1; or
- any asterisked waste stream from the waste list identified as containing asbestos - if they are labelled, packaged and disposed in accordance with the requirements laid out in the Asbestos Regulations 1998; or
- small quantities of waste products containing potentially hazardous components that are not likely to have adverse effects on the environment, such as can reasonably be expected to be contained in the municipal waste stream
(ii) any liquid wastes as defined by condition 1 of this consent, with the exception of landfill leachate; and
(iii) wastes or substances classified as explosive, flammable, oxidising or corrosive under the Hazardous Substances and New Organisms Act 1996.
5. To minimise the potential for hazardous waste to be disposed of at the landfill the following measures shall be taken:
- notice shall be clearly positioned at the landfill entrance to identify the hazardous wastes that are unacceptable at the landfill; and
- random inspections of incoming loads for the presence of hazardous waste shall be undertaken; inspections should be undertaken on a minimum of 1 in 50 loads.
Monitoring and reporting conditions
6. The consent holder shall maintain to the satisfaction of the _______ Regional Council a record of the quantities and types of waste accepted at the landfill.
A copy of this record shall be forwarded to the _______ Regional Council by 1 August each year, unless otherwise agreed in writing by the _______ Regional Council.
7. The consent holder shall immediately notify the _______ Regional Council if any vehicle(s) is/are turned away from the landfill with waste that does not comply with the waste acceptance criteria detailed in conditions 1, 2, 3 and 4. This notification shall include the vehicle registration number and source of the waste (if known).
Review conditions
8. The _______ Regional Council, after consultation with the consent holder, may commence a review of conditions 1, 2, 3 and 4 of this consent within six months of the release of any national guidelines or national environmental standard covering the definition of hazardous waste or landfill disposal controls.
Costs relating to the above review shall be borne by the consent holder.

- Chemical Abstracts Service Registry Number - a unique identifier that tells you, for example, that acetone and dimethyl ketone are the same substance.
- Screening criterion = 20 x TCLP criteria; where contaminant concentration is below the screening criteria, no TCLP test is necessary.
- Adopted from the US EPA TCLP numbers.
- Derived using a constituent specific dilution attenuation factor and the Drinking-water Standards for New Zealand (Ministry of Health, 1995).
- Derived using a constituent specific dilution attenuation factor and the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC and ARMCANZ, 2000).
- Concentration exceeds the limit in the New Zealand Standard Trade Waste By-law (NZS 9201).
The recommended resource consent conditions for Class B landfills are more restrictive.

- solid wastes which, following testing for total concentration, result in total concentration values less than the screening criteria listed in Table 2; or
- any asterisked waste stream from the waste list identified as containing asbestos - assuming they are labelled, packaged and disposed in accordance with the requirements laid out in the Asbestos Regulations 1998; or
- small quantities of waste products containing potentially hazardous components that are not likely to have adverse effects on the environment, such as can reasonably be expected to be contained in the municipal waste stream
(ii) any liquid wastes as defined by condition 1 of this consent, with the exception of landfill leachate; and
(iii) wastes on the NZ Waste List described as liquids, oils, solvents, acids, alkalis; and
(iv) wastes or substances defined as explosive, flammable, oxidising or corrosive under the Hazardous Substances and New Organisms Act 1996.
5. To minimise the potential for hazardous waste to be disposed of at the landfill the following measures shall be taken:
- notice shall be clearly positioned at the landfill entrance to identify the hazardous wastes that are unacceptable at the landfill; and
- random inspections of incoming loads for the presence of hazardous waste shall be undertaken; inspections should be undertaken on a minimum of 1 in 50 loads.

Review conditions
8. The _______ Regional Council, after consultation with the consent holder, may commence a review of conditions 1, 2, 3 and 4 of this consent within six months of the release of any national guidelines or National Environmental Standard covering the definition of hazardous waste or disposal controls.
