a) Do you agree with the proposed requirements?b) If not, what is an appropriate requirement (i.e. limit and test method)? Please provide an explanation of how this impacts on vehicle operability and / or biodiesel manufacturing.

Cold flow properties for Schedule 3 of PPSR:

c) Should the cold flow properties for Auckland/Northland be relaxed in Schedule 3 of the PPSR?

d) If so, what should the limits be for cloud point in winter and summer, and CFPP in winter?

Oxidation stability for B5 blends:

e) In regards to oxidation stability for B5 blends, do you prefer option i, ii, iii or iv? Please provide an explanation of why this is appropriate for New Zealand's regulations.

Individual acids (formic, acetic and propionic) in B5 blends:

f) In regards to individual acids in B5 blends, do you prefer option i or ii? Please provide an explanation of why this is appropriate for New Zealand's regulations.

For Schedule 3 of the PPSR, please provide comment on the following:

g) Do you agree with the proposed requirements?

h) If not, what is an appropriate requirement (i.e. limit and test method) for New Zealand's B5 specifications? Please provide an explanation of how this impacts on vehicle operability and / or biodiesel manufacturing.

i) Are there any other amendments that need to be made to Schedule 3 of the PPSR to incorporate B5 blends within the diesel specification?

For non-retail biodiesel blends specifications regulations, please provide comment on the following:

j) Do you agree with the proposed requirements?

k) If not, what are the appropriate requirements (i.e. limit and test method) for New Zealand's non-retail biodiesel blend specification? Please provide an explanation of how this impacts on vehicle operability or other non-automotive uses of biodiesel and / or biodiesel manufacturing.

Ethanol

Scope of ethanol specification for blending:

l) Is it appropriate that the ethanol specification for blending apply to denatured ethanol? If not please provide an explanation.

Denaturant content:

m) Are there any reasons to allow denaturants other than petrol to be used for denaturing ethanol for blending with petrol?

Ethanol content:

n) Is 95.6% by volume an appropriate minimum requirement for ethanol? If not, please provide an explanation of how this impacts on vehicle operability and / or ethanol manufacturing. If not please provide an explanation.

Solvent Washed Gum:

o) Is the proposed limit of 5 mg/100 ml for solvent washed gum appropriate? If not, please provide an explanation of how this impacts on vehicle operability and / or ethanol manufacturing.

Water content:

p) Is a maximum water content of 1% by volume appropriate for New Zealand's circumstances? If not, please provide an explanation.

Inorganic chloride content:

q) Is a maximum permitted inorganic chloride content of 32 mg/l appropriate for New Zealand's circumstances? If not, please provide an explanation.

Corrosion properties:

r) Is it more appropriate to add corrosion inhibitor to neat ethanol or to the petrol/ethanol blend?

s) Is it necessary for a corrosion inhibitor to be added in all cases?

t) Is it necessary to specify a list of approved corrosion inhibitors?

u) What would be the most appropriate test method for determining the corrosion properties of a petrol/ethanol blend, to ensure that they are no worse than that of petrol?

Non-retail ethanol/petrol blends:

v) Is it appropriate to require ethanol used in non-retail blends to meet the specification for ethanol for blending?

Labelling

w) For labelling requirements of biodiesel and ethanol blends at the point of sale, please provide comment on whether you agree with the proposals. If not, please provide an explanation and alternative requirement (if appropriate).
