1 Environmental Risk Assessment A practical approach Steve Blackburn MSc, AIEMA, CMIOSH,MIIRSM,I Eng MIET

2 Environmental Risk Assessment A practical approach Environmental Aspects ISO requires that an organisation shall establish procedures to identify the environmental aspects of it s activities, products and services that it can control or influence.

3 Environmental Risk Assessment A practical approach Once the aspects of activities have been identified then their impacts need to be assessed and the significance evaluated

4 Environmental Risk Assessment A practical approach Map out key activities Identify environmental aspects for each activity Identify those impacts associated with each aspect Evaluate significance

5 Environmental Risk Assessment A practical approach Environmental Aspects Five main areas could be identified

6 Environmental Aspects Energy

7 Environmental Aspects Energy / Transport

8 Environmental Aspects Waste

9 Environmental Aspects Effluent

10 Environmental Aspects Emissions

11 Environmental Aspects Contaminated Land

12 Environmental Aspects Identified aspects and impacts Evaluate significance Significant aspects Objectives targets and actions

13 Environmental Aspects Factors in assessing significance Significant if Controlled by regulatory requirement Is concern of key stakeholders Has the potential to cause a demonstrable impact Has major financial implications positive or negative Any other criteria deemed significant by the organisation

14 Environmental Assessment Emissions Noise/vibration Fume Particulate Accidental Releases Spills Leaks Fire Explosion Inputs Energy Product Raw Material Activity Outputs Product Service Waste Effluent Land pollutants

15 Control Hierarchy

16 Environmental Risk Assessment A practical approach Pollution Inc Office Block Manufacturing Plant Warehouse Other issues Underground storage tanks Outfall effluent plant Residential housing around perimeter Watercourse to south of site SSSI within 500 metres of perimeter. Waste Storage

17 Environmental Assessment Inputs Warehousing activity Outputs Energy? Waste? Effluent Emissions Land

19 Environmental assessment Inputs Manufacturing Plant Outputs Energy Waste Effluent Emissions Land

20 Environmental assessment Quantify Aspects Inputs Wastes/Effluent/Land Outputs Emissions

21 Operational Controls Pollution Prevention Control Pollution can result from adverse environmental impacts arising from process outputs and other activities.

22 Operational Controls Pollution The introduction of substances or energy into the environment which will :-: Be detrimental to human health of comfort Harm species and ecosystems Interfere with the food chain Damage property Impair amenity Otherwise interfere with the legitimate uses of the environment.

23 Operational Controls ISO Pollution Prevention Use of processes, practices, materials, or products that avoid, reduce or control pollution, which may include recycling, treatment, process changes, control mechanisms, efficient use of resources and material substitution

24 Control Hierarchy

25 Operational Controls Prevention Hierarchy for Waste Change in process design, operation or substance/material/fuel use u so that certain waste outputs are eliminated Reduction Streamlined processes, improved maintenance, efficiency of operations so that the amount of waste is reduced Re-use Re-use waste outputs instead of being released or sent for disposal ie use of re-useable pallets instead of wood.

26 Operational Controls Recovery Reprocess wastes for further use Recycle materials Burn combustible wastes for energy recovery Release or Disposal Ensure releases and wastes meet legal standards Pre-treatment may be required.- this can be as simple as segrgation.

27 Operational Controls Unplanned Releases Prevent Reduce the risk of occurrence Respond to an event Reduce the risk of the pollution reaching a receptor Prevent escalation Minimise impact Respond remediate Clean-up reinstate

28 Pollution Prevention Control BAT General Principles Best available techniques BPEO Best practicable environmental option ALARP As low as reasonably practicable

29 Pollution Prevention Control BAT/BPEO/ALARP All three techniques incorporate the need for pollution control options to be both technically viable and economically feasible These techniques will include both equipment as well as other issues such as housekeeping and training.

30 Pollution Prevention Control Beyond Operational Control Environmental considerations go beyond the site boundary Need to influence suppliers and contractors Customers and products Interface with the local community
