©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Background  Environment Southland are preparing a component their regional plan, which includes the management of hazardous substances.  In effort to assist in the development of their plan, consideration was given to other regional councils plans and rules.  How are other councils managing hazardous substances?

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Hazardous Substances  Provide source and pathways (opportunities) to reach the receptor (sensitive receiving environment).  Management Measures to mitigate or avoid effects

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Current Legislative Framework  Three Acts directly address the management of hazardous substances:  Hazardous Substances and New Organisms Act 1996  HSNO  Land Transport Rule 45001: Dangerous Goods 1999 (Amended in 2005)  Resource Management Act 1991 (RMA)  Discharges  Control of the use of land

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Control of the Use of Land  Responsibility to both regional and district councils  To prevent or mitigate effects from the storage, use, transport and disposal of hazardous substances  Delegation identified in the regional policy statement  So how many regional councils control the use of land for this purpose?

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Key Questions  Are there any regional councils that control the use of land for the storage, use, transport and disposal of hazardous substances?  How are the regional rules drafted?  How easy is it to understand the regional rules?

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Review of Existing Regional Plans and Rules  Twelve regional councils and four unitary authorities Method:  Regional Policy Statements  Regional Plans and Rules  Environmental Outcomes  Ease of Interpretation of Rules

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Regional Policy Statements  16 operative regional policy statements and 2 proposed regional policy statements  Hazardous substances chapter  Mitigating effects to environment from hazardous substances is key issue.  Objectives and policies built around the issue.

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Regional Policy Statements  Regulation of hazardous substances identified as a method for managing effects  Discharges are the responsibility of regional councils  Delegation of the control of the use of land identified in 10 of 12 regional council regional policy statements

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Regional Policy Statements  Use, transport and storage delegated to 2 regional councils (Auckland Regional Council and Environment Canterbury)  Disposal delegated to 4 regional councils (ARC, ECan, Horizons, Environment Bay of Plenty)  2 regional policy statements did not provide any delegation (West Coast Regional Council and Northland Regional Council), so by default, the responsibility goes to the region.

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Regional Plans and Rules  Reviewed 6 regional plans with respect to rules to control land.  Plan status varied: operative, operative in part and proposed.  Very limited rules for managing the use of land for hazardous substances

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Regional Rules  Use of land for storage and use (ECan and ARC)  Use of land for disposal of hazardous substances (ARC)  Most disposal issues were linked to the discharge rules  Use of land for transport of hazardous substances  None, although contingency plans were incorporated in ECan and ARC rules

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Comparison of Regional Rules  ARC approach: Use of land for industrial or trade processes – determining the risk level associated with scheduled activities  Activities schedule relates to risk and area of activity.  Higher risk activities require resource consent, where as low or moderate risk activities may be permitted (with conditions)

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Comparison of Regional Rules  ECan approach: Use of land to store or use hazardous substances – based on specified list of substances (HSNO classification of 9.1A, 9.1B or 9.1C) and their aggregate quantity  Use rules include removal of a storage container.  Classifications include non-complying and prohibited  Sensitive receiving environments (especially the unconfined aquifer areas of Christchurch) trigger more restrictive classifications.

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Comparison of Regional Rules  Both ARC and ECan include management measures in the conditions of their rules  Spill contingency plans (which indirectly picks up some transport risk) and hazardous substance containment measures.  Use of land does not relinquish responsibility to obtain separate authorisation for the discharge of a hazardous substance.

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Ease in Interpretation of Rules  ECan Rule Challenges  Quantity of hazardous substances and HSNO classification  Groundwater protection zones and community drinking water supply protection zones  Failure to meet certain conditions results in a different planning classification - not easy to follow in the drafted rule  Weight of activities when plan is not yet operative (ie prohibited activity)

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Ease in Interpretation of Rules  ARC Rule Challenges  Determination of risk level according to Schedule 3 based on area coverage  Prescriptive conditions for management measures, may be over the top for some low risk activities  Use for disposal of hazardous substances listed as high risk in Schedule 3 and resource consent is required regardless of quantity.

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Conclusions  Most regional councils have delegated the responsibility.  Of those who kept the responsibility, regional plans and rules have only been drafted for two councils.  While there may overlap in responsibilities, at this time there is a gap in the knowledge of the control of land for those who have not prepared regional rules.

©PDP 2007 solutions for your environment PATTLE DELAMORE PARTNERS LTD Conclusions  The rules prepared for the control of the use of land for ARC and ECan based their control using different trigger mechanisms.  Both plans have components which affect the ease in which the regional council officers and the landowner can make a determination of the activity status.  Efficacy of rules has not yet been assessed.
