ACTION REQUEST


--------------------------





2. (SBU) Drawing on the background below, Department
requests AG country Embassies provide the non-paper in
paragraph 6 to appropriate host government officials and
elicit a response. (Note: This is the second of four cables
conveying U.S. proposals. End Note) In delivering this
non-paper, posts should indicate that the U.S. is sharing
this non-paper as part of preparations for the September
21-25 AG plenary and that we would appreciate hearing their
views or any suggestions they may have on the non-paper.
Also, request Embassy Canberra provide the non-paper to the
AG chair for circulation as an official AG document.

REPORTING DEADLINE


--------------------------





3. (U) Embassy should report results of this demarche by
cable before September 7. Please contact ISN/CB Andrew Souza
at 202-647-4838 or via e-mail for further information.

BACKGROUND


--------------------------





4. (SBU) The manufacturing process for many chemical warfare
agents can be extremely caustic, requiring equipment that is
made of specialized corrosion and heat-resistant materials.
To help limit the proliferation of chemical weapons, the
40-country Australia Group (AG) has agreed to require
government permission for exports of this specialized
chemical production equipment. For this year's AG plenary
session, the United States will present three proposals to
refine this control list for dual-use chemical equipment.
One proposal, detailed herein, is to clarify the meaning of
two terms that are currently undefined, 'nominal size' and
'rotor.'



5. (SBU) AG-controlled valves have a nominal size of greater
than 1 cm. U.S. producers of AG-controlled valves have
encountered some difficulty determining nominal size when a
valve's inlet and outlet ports are of different diameters.
To resolve this issue, the United States is proposing that
'nominal size' be defined as the smallest port on a valve.
The term 'rotor' has also caused some confusion for U.S.
manufacturers of AG-controlled pumps, as the term is used to
describe different components in centrifugal and vacuum pump
designs. While vacuum pump rotors do come in contact with
the chemical being pumped, centrifugal pump rotors do not.
Therefore, AG countries are only concerned about the
characteristics of vacuum pump rotors because they could help
determine whether a particular design is appropriate for
chemical warfare agent production. The United States
believes adding a parenthetical indicating that the term
'rotors' applies to vacuum pump rotors only should eliminate
this confusion.

Clarifying the Terms 'Nominal Size' and 'Rotor'

Issue

Should the Australia Group (AG) provide exporters with

STATE 00087596 002 OF 003


explicit definitions of the terms 'nominal size' and 'rotor'
used in the Control List for Dual-Use Chemical Manufacturing
Facilities and Equipment and Related Technology and Software?

Background

At the April 2008 AG Plenary, the United States tabled a
non-paper on clarifications to controls on dual-use chemical
equipment. One of the issues discussed in the paper was the
absence of any definitions for the terms 'nominal size' and
'rotor' used in the control list for dual-use chemical
equipment. Based on our discussions with AG members, during
the 2008 plenary, the United States believes we should
consider clarifying the control list to address this issue.

Discussion

Nominal Size

From our experience, exporters sometimes ask for a definition
of 'nominal size' in the control for valves. This term is
generally understood in the U.S. valve industry to mean the
size of the inlet and outlet ports, or more specifically, the
size of the pipes or tubes which connect the valve to the
process. To provide greater clarity, we recommend adding a
technical note to the control for valves defining the
'nominal size' as the smaller of the inlet and outlet port
diameters.

Rotor

The term 'rotor' is identified in the control for pumps, but
it is not defined. The definition most often used in U.S.
industry is to reference a vacuum pump part. It is also used
by some to refer to a shaft attached to an impeller in a
centrifugal pump or to a shaft with impeller and bearings
attached. In order to clarify the intent of the control, we
recommend adding a technical note to the control for pumps
indicated that the term 'rotors' refers to vacuum pumps only.

Recommendation

The United States recommends that the following technical
notes be added to entries 6 (valves) and 8 (pumps) on the
Control List for Chemical Equipment Manufacturing Facilities
and Equipment and Related Technology and Software:



6. Valves

Valves with nominal sizes greater than 1.0 cm (3/8") and
casings (valve bodies) or preformed casing liners designed
for such valves, in which all surfaces that come in direct
contact with the chemical(s) being produced, processed, or
contained are made from the following materials:

a. nickel or alloys with more than 40% nickel by weight;
b. alloys with more than 25% nickel and 20% chromium by
weight;
c. fluoropolymers;
d. glass or glass-lined (including vitrified or enamelled
coating);
e. tantalum or tantalum alloys;
f. titanium or titanium alloys;
g. zirconium or zirconium alloys;
h. niobium (columbium) or niobium alloys;
i. ceramic materials as follows:


1. silicon carbide with a purity of 80% or more by weight;


2. aluminum oxide (alumina) with a purity of 99.9% or more by
weight;


3. zirconium oxide (zirconia).

Technical note: The 'nominal size' is defined as the smaller
of the inlet and outlet port diameters.



8. Pumps

Multiple seal and seal-less pumps with manufacturer's
specified maximum flow-rate greater than 0.6 m3/h, or vacuum
pumps with manufacturer's specified maximum flow-rate greater
than 5 m3/h (under standard temperature (273 K (0oC)) and
pressure (101.3 kPA) conditions), and casings (pump bodies),
preformed casing liners, impellers, rotors or jet pump
nozzles designed for such pumps, in which all surfaces that
come into contact with the chemical(s) being processed are
made from any of the following materials:

STATE 00087596 003 OF 003



a. nickel or alloys with more than 40% nickel by weight;
b. alloys with more than 25% nickel and 20% chromium by
weight;
c. fluoropolymers;
d. glass or glass-lined (including vitrified or enamelled
coating);
e. graphite or carbon-graphite;
f. tantalum or tantalum alloys;
g. titanium or titanium alloys;
h. zirconium or zirconium alloys;
i. ceramics;
j. ferrosilicon; or
h. niobium (columbium) or niobium alloys;

Technical note: The control term rotors, refers to vacuum
pump rotors only.
