losses. The proposed national GBR will ensure a level playing field for the industry. The targeted approach will ensure that measures are only applied where they are required, in accordance with risk. It is proposed that the GBRs for rural land use will be structured around the main pressures, as follows: • fertiliser and manure management; • land and livestock management; • management and use of pesticides and veterinary medicines; • control of surface water run-off; and • planning tools (e.g. diffuse pollution audits). CONCLUSIONS Managing rural diffuse pollution will depend on a good understanding of land use within catchments. The use of the Total Maximum Daily Loads could play a valuable part in River Basin Management Planning so as to address point and diffuse source pollution collectively. This will require SEPA to implement suitable monitoring strategies and learn from US experience. It will also require SEPA to work collaboratively through partnerships with key stakeholders. A combination of measures will be required to bring about an improvement in the water environment in respect of diffuse pollution pressures. While the WFD requires legislative controls to be introduced, this cannot work in isolation from voluntary programmes, education, promotion of guidance and the provision of financial incentives via farm support payments. A targeted approach that focuses on ‘priority catchments’ is proposed such that the accumulative benefit of adopting Best Management Practices can be gained (as well as effectiveness be measured). The River Basin Management Planning process is crucial to the delivery of WFD objectives and stakeholder engagement is central to this. The Programme of Measures developed for the Scotland River Basin District in relation to diffuse rural pollution will need to founded on a supportive approach.
