The Methodology

The HSNO Act specified that a 'methodology' for processing applications was to be developed. ERMA New Zealand prepared a draft methodology, which was subject to public submissions before finalising the document (ERMA New Zealand 1998). The Methodology [http://www.epa.govt.nz/Publications/Annotated-Methodology.pdf] can be found on the EPA website. This document explains the nature of the information that applicants are responsible for supplying to the EPA:

"In making applications, applicants will be responsible for:

providing necessary and sufficient information (including a risk assessment for the adverse effects which could follow from the introduction of a hazardous substance or new organism) so as to enable the Authority to make its decisions in accordance with the Act and the Methodology Order
providing valid applications in the form prescribed, including unequivocal identification of the hazardous substance or new organism that is the subject of the application
providing a summary of information, including risk assessments and estimated costs and benefits, for public release which has sufficient detail so that it is clear what the application is for and what effects the hazardous substance or new organism might have
providing further information at the Authority's request."

The 'methodology' also gives requirements for submitters:

"People making submissions on publicly notified applications have a responsibility to:

provide relevant information and a clear expression of their views on applications and their attitude to the risks posed.
Where scientific evidence or uncertainty is at issue, the submissions should indicate the scientific basis for any challenge to the information contained in the application."

Also contained within The Methodology [http://www.epa.govt.nz/Publications/Annotated-Methodology.pdf] is an explanation of the decision paths that will be used by the Authority, information on Maori perspectives, the approach to risk, cost and benefit identification and assessment, and how the Authority will deal with uncertainty:

"29. Where the Authority encounters scientific and technical uncertainty relating to the potential adverse effects of a substance or organism, or where there is disputed scientific or technical information the Authority �
(a) Must determine the materiality and significance to the application of the uncertainty or dispute taking into account the extent of agreement on the scope and meaning of the scientific evidence; and
(b) May, where the uncertainty or dispute is material or significant, facilitate discussion between the parties concerned to clarify the uncertainty or dispute.
30. Where any scientific or technical uncertainty or dispute is not resolved to the Authority's satisfaction during its consideration of the application, the Authority must take into account the need for caution in managing the adverse effects of the substance or (to the extent provided for under the Act) the organism concerned.
31. Where the Authority considers that uncertainty arises from an absence of information, or inconclusive or contradictory information, or information from an unreliable source, the Authority may request the applicant to provide further information in accordance with section 58 of the Act and must take full account of any additional information provided.
32. Where the Authority considers there is uncertainty in relation to costs, benefits, and risks (including, where applicable, the scope for managing those risks), the Authority must attempt to establish the range of uncertainty and must take into account the probability of the costs, benefits, and risks being either more or less than the levels presented in evidence. (Hazardous Substances and New Organisms (Methodology) Order 1998)."
