2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
DP-Ø9814Ø-6 maize, referred to as 98140 maize hereafter, has been genetically modified so that it can tolerate application of herbicides containing glyphosate and a range of ALS-inhibiting herbicides such as sulfonylureas for the weeding of the maize crop.

Genetic modification

3. Type of genetic modification:

In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
98140 maize has been genetically modified by insertion of the glyphosate-N-acetyltransferase (gat4621) gene and a modified maize acetolactate synthase (zm-hra) gene, along with the necessary regulatory elements for gene expression in the maize plant (cf Annex1).
The gat4621 gene encodes the GAT4621 protein, which was derived from the soil bacterium Bacillus licheniformis, and confers tolerance to herbicides containing glyphosate. The zm-hra gene encodes the ZM-HRA protein and confers tolerance to a range of ALS-inhibiting herbicides such as sulfonylureas.

6. Brief description of the method used for the genetic modification:
98140 maize was genetically modified using the Agrobacterium-mediated transformation method.

7. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination:
Not applicable.

Experimental Release

1. Purpose of the release:
The purpose of the trialing program is to evaluate 98140 maize, with or without applications of herbicides containing glyphosate and ALS-inhibiting herbicides such as sulfonylureas.

2. Geographical location of the site:
The release is planned at the following locations in Spain in 2008:
- Aragón: Gurrea de Gállego (Huesca), Cogullada (Zaragoza) (2 sites), Remolinos (Zaragoza).
- Castilla-La Mancha: Tarazona de la Mancha (Albacete), La Gineta (Albacete), Alpera (Albacete) (3 sites), Villaseca de Henares (Albacete), Barrax (Albacete).
- Castilla-León: Toral de los Guzmanes (León), Castrillo de la Vega (Burgos), San Llorente de la Vega (Burgos).
- Cataluña: Alcarrás (Lleida) (3 sites).
- Madrid: San Martín de la Vega (Madrid).
- La Rioja: Calahorra (La Rioja).

3. Size of the site (m2):
Each site could have up to 5000 m² sown with the genetically modified 98140 maize subject of this notification, except one of the sites in Alcarrás (Lérida, Cataluña) which could have up to 12000 m² sown with 98140 maize.

4. Relevant data regarding previous releases carried out with the same GM-plant, if any, specifically related to the potential environmental and human health impacts from the release:
Field trials have already been conducted at several locations across maize growing regions in North America, South America and the European Union and no environmental problems were reported for these trials. The transgenic plants appeared normal in all respects. They were indistinguishable from the non-genetically modified maize plants except for being tolerant to glyphosate and ALS-inhibiting herbicides such as sulfonylureas, traits due to the genetic modification.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
No risks to human and animal health or the environment from the deliberate release of genetically modified 98140 maize, tolerant to glyphosate and a range of ALS-inhibiting herbicides such as sulfonylureas, are expected as per information contained in the environmental risk assessment included in the notification.

Brief description of any measures taken for the management of risks:
The pollen shed from the genetically modified plants will be controlled by maintaining a 200-meter isolation distance with any other commercial maize crop. As it is done for any trial with conventional maize, the trial site will be surrounded by agronomic border rows of conventional maize of a similar maturity. The agronomic border rows will be also destroyed at the end of the release.
Grains are fixed on a cob and enclosed in many husks that protect the seeds from outside contact. Thus seed dispersal of individual kernels is not likely to occur. When a few seeds need to be collected for analysis, it will be done by sampling the whole ear and unused seeds will be destroyed.
If needed, the trial could be destructively stopped by mechanical destruction or application of a herbicide other than glyphosate and ALS-inhibiting herbicides, and incorporation into the soil by a deep ploughing.
At the end of the release, all remaining plant matter that has not been harvested for analyses will be destroyed by chopping and incorporating into the soil by a deep ploughing. No plant or plant product coming from the trials will enter the food or feed chains.
After the release, the plot will be visited regularly during the following year in order to ensure removal of maize volunteers, if any. Although volunteer maize cannot generally survive hard winter, maize volunteers, if any, will be monitored in order to ensure their destruction.
No commercial maize crop will be planted on the same area the following year.

Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
The purpose of the planned field trials is to collect specific data on the genetically modified maize in the environment; the field trials are in general not designed to collect specific data linked with environmental impact studies, except for one trial where we will evaluate the impact of the cultivation of 98140 maize on key non-target arthropod populations.
