Conclusions of Phase 1 Review and Assessment
No potentially significant sources of lead emissions were identified during the Council’s Stage 1 Review and Assessment. Further assessment at Stage 2 was therefore not undertaken.
Estimated and Monitored Data
WBC has not undertaken a programme of monitoring for lead. It is anticipated that only locations in the vicinity of major industrial processes which emit significant quantities of lead will report elevated concentrations.
Defra guidance lists the significance of industrial sources, by process type, as a percentage of the total Part A emissions in 2000 and Part B process types that are considered likely to emit significant emissions.
Appendix B details Part A and Part B industrial sources identified within the Council’s Stage 1 report. Consultation with WBC has identified that no further sources have been permitted or planned within the authority, since compilation of the data during the first round of assessments.
From a review of this information and Defra guidance, the Part A processes operated by SEPG and Colthrop Board Mill were identified as having potential to emit sources of lead.
Investigation of the EA’s pollution inventory has identified that neither of the processes are required to report emissions of lead and no changes to emissions from these processes have been identified since the first round of Review and Assessment. It is therefore considered that these processes are unlikely to emit significant emission of lead to result in the AQO being exceeded in 2003 or 2008.
