Alexander Sandy Elliott HS 4 Presentation My original

Alexander (Sandy) Elliott HS 4 Presentation

• My original written evidence for HS 4 (January 12) addressed the robustness and fitness-for-purpose of methods for establishing nutrient load limits proposed by Dr Canning in HS 1. • The scope of my assessment excludes setting of concentration limits, and excludes the methods to allocate load limits to land-use classes

• In my original written evidence I raised a number of concerns about the methods used by Dr Canning, and concluded that the methods were not sufficiently clear or robust. • Since I submitted my original evidence, Dr Canning has prepared revised evidence (dated 26 January) to be presented in HS 4. That revised evidence includes a number of amendments and clarifications to the original evidence, which responds to some of my concerns. The revisions impact on my original conclusions.

• Several of my original concerns have been addressed in Dr Canning’s revised evidence. However, I still have significant questions and concerns about the methods. • It has been tentatively agreed with Dr Canning to undertake caucusing later this week. I expect this will address some of my remaining concerns.

• In my view the proposed methods will remain a coarse approach for establishing load limits. • A table summarising key points in my original evidence, Dr Canning’s response in his revised evidence, and my updated view has been tabled today.
