5.7.1 Hazardous Facilities Management

1. The Hazardous Facility Screening Procedures (HFSP), shall be used to identify the appropriate level of scrutiny to process an application for a proposed hazardous facility.
2. Where appropriate, site management systems and emergency plans shall be prepared and operated. Any activity operator using, producing or storing Hazardous Substances shall, prior to the commencement of the activity, consult with the District Council to determine whether a site management or emergency plan is required.
3. The HFSP will be used as a screening tool to assist in making decisions on:
   
   1. Whether a proposed hazardous facility is permitted, subject to defined minimum conditions; or
   2. Whether it requires a consent and additional, merit-based assessment of risks.

Advice Note: The HFSP shall be applied to all proposed new facilities using or storing hazardous substances.

5.7.2 Consent Status Matrix

1. Permitted Activities
   
   Any hazardous facility with an Effects Ratio equal to or below the Effects Ratio specified for the zone in which it proposes to locate, as indicated in the Consent Status Matrix below.
2. Discretionary Activities
   
   Any hazardous facility with an Effects Ratio above the Effects Ratio specified for the zone in which it proposes to locate, as indicated in the Consent Status Matrix below.
3. If any hazardous facility or sub-facility is located within 20 metres of a sensitive water resource such as a stream, a lake or a water bore, all permissible hazardous substances quantities need to be multiplied by a factor of 0.3.
4. The following quantities of hazardous substances are permitted within the zones as listed in association with the typical activities listed.
   
   For other substances and activities the consent status matrix should be applied using the hazardous facilities screening procedures. Council staff can assist you in the use of the procedure.
   
   As is stated in 5.7.2 (ii) above, the use of quantities above those stated will require a discretionary resource consent. The multiple use or storage of substances shall be deemed to be a restricted discretionary activity unless otherwise complying with 5.7.3 (i) and 5.7.2 (iv) the rural separate sub-facilities column.

5.7.3 Exemptions From The HFSP

The following activities shall be exempted from compliance with the HFSP and the conditions in 5.7.4, but shall comply with the remainder of this Plan:

1. Existing facilities will not be subject to the HFSP unless they significantly expand or alter their operations. A significant alteration occurs when the effects of the use are not the same or similar in character, intensity or scale as previously, as defined in Sections 10, 10A and 20 of the Resource Management Act. In circumstances where the expansion or alteration results in an increase in storage capacity, or the use of hazardous substances, of 20% or more, or there is a change in the type of process carried out on the site, the operator shall apply for and receive a Certificate of Compliance pursuant to Section 139 RMA prior to undertaking the alteration or expansion.
2. The retail sale of petrol, up to a storage of 100,000 litres of petrol in underground storage tanks and up to 50,000 litres of diesel, provided that the "Code of Practice for the Design, Installation and Operation of Underground Petroleum Systems", published by the Department of Labour - OSH, is used.
3. Retail LPG outlets, with storage of up to 6 tonnes (single vessel storage) of LPG. Council shall have regard to the "Australian Standard (AS 1596-1989) for LP Gas Storage and Handling - Siting of LP Gas Automotive Retail Outlets".
4. Liquid milk storage provided that any spillage is prevented from entering a water course or body or from seeping into an underground water supply.
5. Other Activities:
   1. Trade waste sewer and waste treatment or disposal facilities;
   2. Storage or use of hazardous consumer products for private domestic purposes;
   3. Retail outlets but not wholesaling for the domestic usage sale of hazardous substances (e.g. supermarkets, hardware shops, pharmacies);

5.7.4 Minimum Conditions For Hazardous Facilities

The following minimum conditions address the discharge of liquids and solids and shall apply to all hazardous facilities.

A. SITE DESIGN

Adherence to the following design guidelines is deemed to comply with this condition:

3.1 Spill Containment System

The parts of the hazardous facility site described in parts A.2 and A.3 above shall be serviced by a spill containment system that is:

1. Constructed from impervious materials resistant to the hazardous substances used, stored, manufactured, mixed, packaged, loaded, unloaded or otherwise handled on the site.
2. Able to contain the maximum volume of the largest tank used, or where drums or other containers are used, able to contain half of the maximum volume of substances stored or otherwise in accordance with the requirements of the Toxic Substances Regulations 1983 (regulation 17A (3)) relating to connected bulk containers where relevant.<
3. Able to prevent any spill or other unintentional release of hazardous substances, and any stormwater and/or fire water that has become contaminated, from entering the stormwater drainage system.
4. Able to prevent any spill or other unintentional release of hazardous substances, and any stormwater and/or fire water that has become contaminated, from discharging into or onto land and/or water (including groundwater and potable water supplies) unless permitted by a resource consent.

3.2 Stormwater Drainage

All stormwater grates on the site shall be clearly and appropriately labelled to ensure no hazardous substances enter stormwater systems.

3.3 Washdown Areas

Any part of the hazardous facility site where vehicles, equipment or containers that are or may have become contaminated with hazardous substances are washed shall be designed, constructed and manage

1. Entry or discharge into the stormwater drainage system.
2. Entry or discharge into the sewerage system unless permitted by the sewerage utility operator
3. Discharge into or onto land and/or water (including groundwater and potable water supplies) unless permitted by a resource consent.

B. Underground Storage Tanks

Underground tanks for the storage of petroleum products shall be designed, constructed and managed to prevent leakage and spills.

Council shall have regard to the Code of Practice for "Design, Installation and Operation of Underground Petroleum Systems" (Department of Labour - Occupational Safety and Health) is deemed to be one method of complying with this condition.

C. Signage

Any hazardous facility shall be adequately signposted to indicate the nature of the substances stored, used or otherwise handled. Adherence to the following methods will be deemed to be compliance with this rule:

1. The Code of Practice for “Warning Signs for Premises Storing Hazardous Substances” of the New Zealand Chemical Industry Council, or any other Code of Practice approved by the New Zealand Fire Service.
2. Regulations under the Hazardous Substances and New Organisms Act 1996 including the transitional Dangerous Goods Regulations and any relevant subsequent regulations.

Adherence to the Code of Practice for "Warning Signs for Premises Storing Hazardous Substances" of the New Zealand Chemical Industry Council, or any other Code of Practice approved by the New Zealand Fire Service is deemed to be one method of complying with this condition.

D. Waste Management

Explanation

Council has adopted an approach to managing hazardous facilities that focuses on assessing potential adverse effects of three kinds:

• Effects caused by fire and/or explosion
• Effects on human health
• Environmental effects

Possible adverse effects of hazardous substances can be predicted by the hazard of the substance and the anticipated consequences of its release. Adverse effects include:

• contamination of water, soil and air
• short and long term damage to ecosystems
• accumulation of persistent substances in the bodies of humans and animals, resulting in chronic and/or long term damage to their health
• acute damage to human health through exposure to substances affecting skin, mucous membranes, respiratory and digestive systems
• damage to the environment from fire or explosion events
• damage to human health and property from fire or explosion events

In order to assess the hazard posed by various substances and the risk they present, Council has adopted the Hazardous Facility Screening Procedure for use in assessing hazardous activities or facilities.
