  AND

  • Not from a HAIL site:

    • where there has been intensive use of chemicals, such as chemical storage and mixing sheds or within the footprint of former glasshouses or areas of similarly high intensity horticultural use; or

    • contaminated by other activities (e.g. asbestos or fill sites).

• Greater than 25m3 of HAIL A10 soil requires a full hazardous waste manifest and assessment.

  [RM975261-D(7.2)]

The discharge of municipal solid waste and leachate shall occur only on the area of the site identified as Gully 1, as shown in Plan Number 20/49-02 York Valley Sanitary Landfill Sites, Designated Areas.

Asbestos wastes shall only be accepted in accordance with the Asbestos Regulations 1983, or subsequent amendments to the regulations.

Medical wastes shall only be accepted in accordance with NZS 4304: 1990 "Health Care Waste Management" or subsequent amendments to the standard.

The maximum volume of liquid wasted accepted for disposal shall not exceed 150 tonnes per year.

Any liquid waste accepted for disposal shall comply with Conditions (7) and (10) (waste acceptance and handling conditions). The maximum concentration of potentially hazardous components in the liquid waste shall not exceed the TCLP limits specified in Condition 6 of this consent. The quantity, type and source of liquid wastes accepted for disposal, and the name of the liquid waste contractor, shall be recorded and reported to the Council’s Monitoring Officer on an annual basis.

The Consent Holder shall take all practicable steps to reduce the volume of liquid waste accepted for disposal, with a view to eliminating liquid waste disposal at the site.

With the exception of medical waste and asbestos wastes, no hazardous waste shall be accepted for disposal at the landfill. The definition of "hazardous waste" shall be:

i.        Wastes which exhibit one or more of the following characteristics:

• Explosive

• Gas

• Ignitable (as defined in USEPA 40 CFR Part 261)

• Liable to spontaneous combustion

• Emit flammable gases on contact with water

• Oxidising

• Organic peroxides

• Infectious

• Radioactive

• Corrosive (as defined in USEPA 40 CFR Part 261)

• Liberates of toxic gases in contact with air or water

• Capable, by any means after disposal, of yielding another material, e.g., leachate, which possess any of the above characteristics

ii.      .

iii.     Wastes which exhibit one or more of the following characteristics, which following testing using the US EPA Toxicity Characteristic Leaching Procedure (TCLP) results in maximum concentration of contaminants in excess of TCLP criteria detailed in Schedule 2, attached to this consent:

• Poisonous substances

• Toxic substances (chronic or delayed effects)

• Eco-toxic substances

Where TCLP limits do not exist for a substance for which a disposal request is made, the TCLP limit shall be set at 100 times the drinking water standard for that substance.

The definition of "hazardous waste" shall not include small quantities of waste products containing potentially hazardous components that are not expected to have adverse effects on the environment, such as can reasonably be expected to be contained in the municipal waste stream, and as could be contained within up to 5 cubic metres of soil from sites identified as HAIL A10 on the Hazardous Activities and Industries List (HAIL) as further defined and controlled in the “Untested HAIL A10 Soil Management Plan – York Valley Landfill”. Where such sites also have other HAIL classifications, an assessment prepared by a contaminated land specialist shall be required to confirm either: 1) the soil does not come from areas of such sites where these other potentially contaminating land-uses have occurred; or 2) that the soil meets the Schedule 2 criteria.

To minimise the potential for hazardous waste to be disposed of at the landfill the following measures shall be taken:

• the Consent Holder shall only accept potentially hazardous wastes accompanied by a completed Hazardous Waste Manifest which demonstrates that the waste complies with i and ii above;

 Advice Note: This provision does not apply to up to 25 cubic metres of soil from sites identified as HAIL A10 on the Hazardous Activities and Industries List (HAIL) as further defined and controlled in the “Untested HAIL A10 Soil Management Plan – York Valley Landfill”. Condition D7.1 applies for 5 – 25 cubic metres quantities from former “broad-acre” areas of HAIL A10 sites and condition D7 applies for <5 cubic metre quantities from sites identified as HAIL A10.

• notice shall be clearly positioned at the landfill entrance to identify the hazardous wastes which are unacceptable at the landfill; and

• random inspections of incoming loads for the presence of hazardous waste shall be undertaken.

Between 5 and 25 cubic metres of soil, based on in situ volume, from former broadacre areas of HAIL A10 sites may be accepted at the landfill without the Hazardous Waste Manifest demonstrating compliance with i and ii of Condition D7, provided that compliance with i and ii of Condition D7 is demonstrated prior to final disposal within the landfill. Control of acceptance, temporary storage, testing, and final disposal of the untested soil from former broad-acre HAIL A10 areas shall be undertaken in accordance with the “Untested HAIL A10 Soil Management Plan – York Valley Landfill”. For the purposes of this condition “broad-acre areas of HAIL A10 sites” includes areas on HAIL A10 sites where cropping or orcharding has occurred where pesticides are likely to have been applied, but does not include:

i.          Soil from areas at HAIL A10 sites where there has been intensive use of chemicals, such as chemical storage and mixing sheds or within the footprint of former glasshouses or areas of similarly high intensity horticultural use; or

ii.         Soil at HAIL A10 sites that is contaminated by other activities (e.g. asbestos or fill sites).

A final version of the “Untested HAIL A10 Soil Management Plan” to incorporate amended conditions D7 and D7.1 shall be provided to Council’s Manager Consents and Compliance for certification at least 1 month prior to the first acceptance of any HAIL A10 soil under these conditions. The final version shall only differ from the Draft that was included within the application by the addition of the conditions and any directly related subsequent amendments required. No HAIL A10 soil shall be accepted in accordance with conditions D7 or D7.1 until the final version of the “Untested HAIL A10 Soil Management Plan” has been certified by the Council’s Manager Consents and Compliance.

The following substances will only be permitted where approval has first been given by Nelson City Council and suitable arrangements made for its proper placing and immediate covering in the landfill:

a) loads of fish and animal wastes

b) any scheduled poisons or other hazardous chemicals

c) any dangerous goods or other hazardous materials

d) any liquid waste

Approval for the disposal of these substances will only be granted where there is not a satisfactory alternative method available to the industries concerned and in the case of substances referred to in DN1.6.xvi (b) and DN1.6.xvi (c) only in an approved area of the landfill.
