A.  Amendment to Crop Group 3 (B. Schneider/H. Chen).

The SAC discussed a number of proposed changes to Crop Group 3 (Bulb
vegetables).  The proposed changes and recommendations are presented in
detail in a forthcoming memorandum from B. Schneider to B. Madden and
are outlined below.

1.  Amend the name of the crop group from “Crop Group 3:  Bulb
Vegetables (Allium spp.) Group” to “Crop Group 3:  Bulb Vegetables
Group.”

2.  Expand the group from 7 commodities to 25 commodities.

3.  Add Subgroup 3A:  Bulb onion subgroup and Subgroup 3B:  Green onion
subgroup.

4.  Amend the terminology from “dry bulb” to “bulb.”

5.  Amend the scientific names in 40 CFR 180.41 and 40 CFR 180.1(h) as
appropriate.

The SAC concurred on all of these items, adding that the subgroup names
in Item 3 be changed to “Onion, Bulb, Subgroup 3A” and “Onion,
Green, Subgroup 3B” in keeping with the current conventions.

Dr. Schneider made the following additional recommendations:

6.  Amend the commodity definitions in 40 CFR 180.1(h) to reflect
changes in the bulb vegetables crop group.

7.  Include fresh chive leaves and fresh Chinese chive leaves in the
expanded Crop Group 3.  Dried chive leaves will remain in Herb and Spice
group.

8.  Update HED SOPs 99.6 (blended/non-blended foods)and 2000.1
(commodity translations) to reflect changes to the bulb vegetable crop
group.

9.  Provide guidance on the correct terminology for the bulb vegetable
crop group and the new subgroups.

The SAC concurred on those recommendations as well.

B.  Transgenic glyphosate-tolerant crop testing proposal (G. Kramer)

DuPont has proposed an alternative study design for assessing residues
of glyphosate and n-acetyl glyphosate in transgenic crops.  EPA had
previously suggested four side-by-side bridging trials per crop
conducted in different growing regions in order to establish that the
current glyphosate tolerances are adequate to cover residues in
transgenic crops.  DuPont has proposed increasing the number of trials
by 50% and foregoing any side-by-side comparison using “Roundup
Ready” crops.  This request is based on DuPont’s concerns about
using a Monsanto proprietary product in their field trials.

The SAC determined that, in the absence of bridging data, a full set of
field trials (as specified in OPPTS 860.1500) would be required.
