Risk Mitigation Tools A shortlist of tools ready to go

Objective
• Shortlist of the RMM “ready to go” from the workshop point of view
• Discussion to reveal:
• Practical questions • Remaining hurdles • Potential solutions

Ground water & drainage

Risk mitigation concept for drainage: what can be implemented now?
• Reduced application rate is already in place throughout the EU.
• Restrictions to application timing are in place in many MS. No legal change should be required – just the means to enforce the restriction.
• Simple modifications to application through e.g. banded spraying are less widely implemented. This might require a new S-phrase as well as the means to enforce the restriction.

Risk mitigation concept for drainage: what can be implemented now?
• The other mitigation measure that can be implemented relatively easily is a restriction based on soil type

Risk mitigation concept for drainage: what can be implemented now?
• Restriction based on soil type. • S-phrase is already in place. • Implementation by MS requires:
• A framework to demonstrate the effect on PECsw. FOCUS SWS and other surface water modelling tools provide a good start.
• National labelling frameworks that allow the restriction to be imposed.
• Means to enforce the restriction.

Some Questions to the Audience
As these measures are already implemented in at least some member states: • What what prevents wider adoption? • What could be done to improve acceptance?
