  1. EnvironmentalProtection of European Marine Sites Prepared by: Ross Brown

  2. A chemical industry perspective? Site operation Consent to discharge PPC H1 Environmental Impact Environmental baseline PPG Site development Planning consent Planning regs

  3. Environmental quality status & ecosystem health? Combined impact vs environmental susceptibility? and sustainability? A stakeholder approach

  4. SOLUTIONS Ecosystem approach • Managing the activities & demands that humans make on • the environment, not managing ecosystems themselves. River basin management plan (WFD) • Characterisation of river basin – • Review of activities impacting on water status • Sub-basin plans Biodiversity Action Plan • Conservation management plans eg. SES, ASERA, MBMS • HAPs, SAPs

  5. Monitoring in the Severn estuary Clients: CCW, EN, chemical & steel industries NMMP site 615

  6. Severn estuary European Marine Site Major interest features

  7. Conservation value vs. status?

  8. What about primary production?

  9. Characterisation of SW European Marine Sites reports Activities • Discharges : industrial, municipal, diffuse agricultural? Pollutants • Nutrients, BOD, Metals, PAHs, PCBs, pesticides • EQS, sediment guidelines, trends? Impacts (targets) • Migratory fish, demersal fish, inverts & birds • Sediment dwellers, biomagnification?

  10. Conclusions – what is needed? • A complete local BAP • Provide guidance on ecological / conservation status • ie departure from reference or target conditions? • Consider all activities with a potential to impact • Involve stakeholders • Advertise ASERA (400 visitors since Feb 2003) • Distil exisiting information • Consider existing EIAs, IPPC and COMAH documents • Identify acute then chronic toxicity (DTA) • Combine & focus monitoring – spatial vs temporal • Update GQA for estuaries

  11. Declining Cd concentrations in sediment

  12. Declining Cd concentrations in biota Fucus vesiculosus Carcinus maenas

  13. Long-term trend in mudflat fauna

  14. Mudflat fauna relative abundance 50-1500 indivs or 1-30 grams per 0.1 m2

  15. 50 -50 150 250 350 450 550 650 750 850 950 -850 -750 -650 -550 -450 -350 -250 -150 1050 1150 Low water invertebrate fauna diversity 14 12 Outfall 10 8 Number of taxa 6 4 2 0 Downstream (+) Distance from outfall (m) Upstream (-)

  16. Saltmarsh NVC community types Pioneer SM6-8 Puccinellia SM13 Elymus SM24

  17. Effluent dispersion: Neap LW +4hrs

  18. Effluent dispersion: Neap LW +10hrs

  19. Effluent dispersion: Neap LW +13.5hrs

  20. Effluent dispersion: Neap LW +19.5hrs

  21. AstraZeneca whole effluent testing Ecotoxicity expressed as % of untreated 2004 effluent

  22. Direct Toxicity Assessment EA policy “elimination of acute toxicity from receiving waters” EA target EA manage 20 existing toxicity based consents. Target is to achieve 85% reduction in no. of complex chemical effluents causing acute toxicity ie a further 25 discharges will be targeted

  23. PPC : HI Guidance for DTA Tiered Risk-based Approach • Tier 1. Require DTA screening data if direct discharge + estimate of worst-case dilution & dispersion - unless low impact installation or case made to show inappropriate • Tier 2.Require full DTA characterisation • 3 trophic levels (algae, invert + fish) + dilution and dispersion modelling • Tier 3.Toxicity Tracking & Identification
