UK: Two day technical fate and behaviour assessment of plant protection products workshops

The Chemicals Regulation Directorate (CRD) will be holding two identical two-day workshops on technical aspects of the environmental fate and behaviour assessments of plant protection products. The workshops will be held at The Chemicals Regulation Directorate in York on Tuesday/Wednesday 16th/17th September and Tuesday/Wednesday 23rd/24th September, 2014. Registration will be from 9:00 am. The workshop will start at 9:30 am and finish at 4:00 pm on the second day. The cost per delegate will be £520.00 (plus 20% VAT).

Format of the day / Target Audience

This course will be specifically designed for those with at least a basic working knowledge of environmental fate and behaviour who want to develop their expertise in this area further. The course will present attendees with an overview of environmental fate assessments at EU level and highlight the key issues that they must take into account when preparing product approval submissions. The course will cover basic introductions to the use of the FOCUS groundwater and surface water models and various refinement options, as well as UK specific environmental exposure requirements. The course will comprise a mixture of presentations and workshops with worked examples. By the end of the course, participants will have a better appreciation of this area of pesticide risk assessment and be better able to prepare regulatory submissions for plant protection products.

Topics of discussion

It is proposed that the training will cover areas such as:
  • Overview of the EU process, the EFSA conclusion, key endpoints, data gaps and critical areas of concern
  • The use of the risk envelope approach
  • Zonal assessment and national addenda
  • FOCUS groundwater modelling (e.g. with PEARL and PELMO)
  • FOCUS surface water Steps 1, 2 and 3 and risk mitigation with SWAN
  • UK specific environmental exposure assessment requirements (groundwater using FOCUS MACRO, spray drift, buffer zones and drift reduction technology, first tier drainflow and higher tier refinement options, including an introduction to the latest version of Webfram)
  • Common problems with applications
  • Future developments, new data requirements, EFSA activities, PPR opinions and guidance documents
Given the nature of these events, places will be limited to a maximum of 16 people for each workshop, and will be issued on a first-come first-served basis .
