Provision of ongoing support to PSD for issues related to regulatory use of the HardSPEC model - PS2236

Description
The HardSPEC model (Hollis et al, 2004) for calculating first tier PEC’s in surface and groundwater resulting from herbicide use in Hard Surface environments has, since April 2004, been approved for providing predictions to support UK regulatory submissions. Despite a relatively high use of herbicides in many hard surface environments, assessing their fate under these scenarios is very new and, as the model is the first of its kind to be developed and used for this purpose, none of the potential users had experience of it. As a result since January 2005, a contract has been in place with the model developers at Cranfield University’s National Soil Resources Institute (NSRI) and the Central Science Laboratory to provide support and advice on its use (PS2221). This contract has provided significant support for both regulators in the Pesticides Safety Directorate and members of Industry preparing data for regulatory submissions. In addition, it has resulted in the development of revised versions of the model which were required to address issues which arose during its use over the last three years. To ensure a structured approach to use and development of the HardSPEC model, a Steering Committee has been set up with a brief to ‘Advise on issues related to use of the HardSPEC model within the UK regulatory framework and to agree and help prioritise areas for development or adaptation of the model’. The Steering Committee comprises representatives from the Pesticides Safety Directive, Industry, the Environment Agency and Water UK as well as the model developers.

The current support contract will be completed at the end of January 2008 and the Hard Surfaces Steering Committee has advised that continuing support to PSD and Industry will be necessary over the next few years. In addition, Mr. John Hollis, the principal developer of the HardSPEC model is now an Independent Consultant and will soon be retiring. It is therefore necessary to ensure that his expertise is passed on to appropriate scientists in the current support group.

Finally, it is envisaged that further model development or adaptation may be necessary as specific issues arise over the next few years. Where such modification is considered necessary but is relatively significant, it is likely that it will be carried out as a separately funded R&D project. However, where any necessary modification is relatively minor, it would be most efficient to carry it out as quickly as possible within a second phase of the support contract.

The main objective of this project is therefore to ensure the provision of continuing support to staff of the Pesticide Safety Directorate and the agro-chemical industry involved in regulatory submissions for products where use of the HardSPEC model is required. This will be achieved by:

Provision of on-line advice to users of the HardSPEC model.

Organising regular meetings of the Hard Surfaces Steering Committee and, where considered necessary, training seminars to update users on model developments.

Undertaking minor developments of the HardSPEC model that may be needed to correct any ‘bugs’ that are identified during its use and to address any minor issues that may arise during the period of the project.

Objective
The objectives of this project are to :

1. Provide an on-line HardSPEC support service to staff of the Pesticide Safety Directorate.
2. Organise regular meetings of the Hard Surfaces Steering Committee and, where considered necessary, training seminars to update users on model developments.
3. Implement minor development of the HardSPEC model to correct any ‘bugs’ that are identified during its use and to cater for minor issues that may arise.
