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

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

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
