Appendix 8 - Lists for hazardous facilities and contaminated land

1.0 Introduction
2.0 Hazardous activities and industries list
3.0 List of contaminated and potentially contaminated land
4.0 List of classifications for common substances

1.0 Introduction

This appendix contains a number of lists for use in conjunction with part 9 - Hazardous facilities and contaminated land. The lists are as follows:

• The hazardous activities and industries list (HAIL)
• A list of contaminated and potentially contaminated land
• A list of classifications for common substances.

2.0 Hazardous activities and industries list

2.1 Introduction

The hazardous activities and industries list (HAIL) is a compilation of activities and industries that are considered likely to cause land contamination as a result of the use, storage or disposal of hazardous substances. The HAIL is a revision of the list of industrial activities first published in the Australia New Zealand Guidelines for the Assessment and Management of Contaminated Sites 1992.¹ The HAIL is intended to identify most situations in New Zealand where hazardous substances could cause, and in many cases have caused, land contamination.

In some cases a generic activity involving hazardous substances is listed, irrespective of the industry, for example, petroleum storage. In other cases, an industry is listed on the basis that certain activities typical of that industry involve storage, use, or disposal of hazardous substances, and therefore all sites within that industry should be considered - for example the timber treatment industry. In other cases, particular activities are a small part of a particular industry, with the activity generally localised within larger sites. For example, animal dip sites are listed, but farming is not because dip sites are only a small part of a farm and farming, in general, do not have a high potential to contaminate the complete farm.

The HAIL should be used for consistently reporting on site history (see Contaminated Land Management Guidelines No.1: Reporting on Contaminated Sites in New Zealand, MfE 2003). In accordance with MfE guidelines, the council uses the HAIL for identifying potentially contaminated sites.

2.2 The HAIL

The HAIL (see below) defines industries and activities which typically use or store hazardous substances that could cause contamination if these substances escaped from safe storage, were disposed of on the site, or were lost to the environment through their use. The fact that an activity or industry appears on the list does not mean that hazardous substances were used or stored on all sites occupied by that activity or industry, nor that a site of this sort will have hazardous substances present in the land. The list merely indicates that such activities and industries are more likely to use or store hazardous substances and therefore there is a greater probability of site contamination occurring than other uses or activities. Conversely, where an activity or industry that does not appear on the list, this does not guarantee such a site will not be contaminated. Each case must be considered on its merits, considering the information at hand. In applying the list, it must be remembered that the activity may only have occupied a small part of the site, and therefore the possibility of contamination will also be for a small part of the site.

31. Mining and extractive industries and mineral processing - including chemically or physically extracting metalliferous ores, exposure of faces or release of groundwater containing hazardous contaminants and storing hazardous wastes, including waste dumps and tailings dams, but not gravel extraction (just note that these areas can be included because of fuel storage).

3.0 List of contaminated and potentially contaminated land

The following tables list sites identified as having at one time had activities taking place which have or may have resulted in site contamination. A resource consent is required in accordance with the rules under clause 9.6, 'contaminated land' prior to any remediation or redevelopment taking place on these sites. These sites are also identified on the planning maps.

3.1 List for inner islands

Note: The above list does not necessarily identify all contaminated or potentially contaminated land for the inner islands. The list may be updated by means of a variation or plan change as new information becomes available.

3.2 List for outer islands

Note: the above list does not necessarily identify all contaminated or potentially contaminated land for the outer islands. The list may be updated by means of a variation or plan change as new information becomes available.

4.0 List of classifications for common substances

The table below identifies the HSNO subclasses for some commonly used hazardous substances. This information is to assist users in applying table 8.1 Hazardous facilities consent status.

Note:

This table does necessarily list all the chemicals that you may seek to use. Be aware that all hazardous substances including petrochemicals, agrichemicals, explosives, fumigants, veterinary medicines, timber preservatives, antisapstains, antifouling paints and vertebrate toxic agents are controlled by the Hazardous Substances and New Organisms Act 1996 and have been assigned a hazard classification. The legal mechanism for transfer was by regulation for explosives or in the case of all other substances, by notice in the New Zealand Gazette. Transfer and gazette notices which list all substances and their hazard classifications are available from the Environmental Risk Management Authority (ERMA) New Zealand by contacting them on 0800 376 234 or online at www.ermanz.govt.nz/hs/transfer/docs.html
