It is also stated which scenarios are relevant for risk assessment within the Central  Zone and what should be included in a modelling report.
• For surface water modelling, in addition, it is reported how STEP 4 refinements can be conducted and reported in a Dossier.

• Guidance is given on the use of the Q10 value in modelling.
• For Home and Garden use, a tiered approach is presented. The first 2 tiers are included in the Harmonisation Documents, further refinements, if needed, could be done on Member State level.
