  1. Oil Spill Shoreline Clean-up

  2. Course Outline • Safety issues surrounding shoreline operations • What SCAT is and how it affects shoreline operations • Shoreline response techniques • What they are • Operational effectiveness • Environmental impact

  3. Course Outline (continued) • Logistical support for shoreline operations • Field training

  4. Shoreline Supervisor The most important position on the beach • Must methodically organize a long term, efficient response • Must ensure all personnel adhere to strict code for minimizing environmental impacts • Must assess all hazards and ensure personnel are safe

  5. First Aid Requirements • WCMRC follows all WorkSafeBC standards and requirements: • Occupational First Aid Level-1 on all crews • Occupational First Aid Level-3 at any spill site over 20 minutes from a health facilities • Occupational First Aid Level-3 at any spill site with 20 or more workers

  6. Shoreline Safety • Personnel training requirements • Site Specific Safety Rules • Evacuation Route(s) • Emergency Notification Procedures • Initial safety assessment

  7. Shoreline Safety (continued) • Daily Tailgate Safety Briefings • Everyone MUST attend • Sign Accountability Sheet • Safety watch/obligation to subcontractors

  8. Shoreline Response PPE • Requirements depend on risk: • Hardhat • Safety glasses • Steel toe boots • Disposable raingear • Gloves and liners • Rubber boots • PFD

  9. Typical Shoreline Safety Hazards • Slips, trips and falls • Sharp edges and cuts • Inclement weather • Physical exhaustion • Improper working technique

  10. Shoreline Safety Hazards cont. • Ingestion hazards • Tidal concerns • Working around moving vehicles and equipment • Wildlife encounters

  11. Personnel Decontamination

  12. “Dry” Shoreline Decon Station • Establish parameter boundary • Logical progression • Collect waste • Leave reusable equipment in “hot zone”

  13. Decon Procedures • Tool/Equipment Drop • Left in hot zone for reuse • Cleaned by entrants so as to not further contaminate support zone • Gross Decon • As much contamination is removed as possible • Usually done by physical means • Contain all runoff water • Entrant assist with gross decon to reduce contamination to other personnel

  14. Decon Procedures • Wash and Rinse Station • Chemical solution used to neutralize the contaminant or to ease with removal from entrant’s PPE • Usually a pre-mixed solution and brushes • Scrub entire person • Rinse off neutralizing chemicals with clean water • Control all runoff water

  15. Decon Procedures • Removal of Outer Clothing and PPE • Rainsuit, boots, outer gloves, face splash-shield, safety glasses, respirator removed and disposed of • Segregate if possible • Inner Clothing Removal • Only if necessary • Medical Monitoring • Only if necessary

  16. Decon Procedures

  17. Decon Procedures

  18. Prepackaged Decon Station

  19. Special Shoreline Safety Issues Remote/Isolated Shoreline Considerations

  20. Special Shoreline Safety Issues How will shoreline workers be transported to the site? • Fixed wing floatplane • Helicopter • Crew boat

  21. Special Shoreline Safety Issues How will shoreline workers be cared for once they have been left on-site? • Poor weather shelter • Toilet facilities • Overnight accommodations

  22. Role of Helicopters and Shoreline Response Operations • Personnel transport • Logistical transport • Observation • Medical emergencies

  23. Helicopters Safety Issues

  24. Special Shoreline Safety Issues Helicopters

  25. Special Shoreline Safety Issues Helicopters and Sling-loading

  26. Role of ATVs and Shoreline Response Operations • Personnel transport • Logistical transport • Observation • Medical emergencies

  27. Special Shoreline Safety Issues ATVs

  28. Special Shoreline Safety Issues Night Operations

  29. SCAT: What is it? Shoreline Cleanup Assessment Team

  30. Sub tidal habitats Birds Marine Mammals Terrestrial Mammals Terrestrial Plants Fish and Shellfish Reptiles Recreation Management Area (nature preserves, parks, refuges) Resource Extraction (commercial fishing areas, water intakes, seafood harvest sites) Cultural Resources Special SCAT Considerations

  31. SCAT Impact to Shoreline Response Operations • Check effectiveness of shoreline response technique • Monitor progress of total shoreline clean-up • Ensure minimal environmental impact of response technique

  32. Special Shoreline Response Issues • Wildlife • Birds • Marine Mammals • Do not touch, whether alive or dead • Flag with stake and report to Wildlife unit

  33. Special Shoreline Response Issues (continued) • Archaeological/Cultural Resources • Response operations may uncover undiscovered archaeological features or artifacts • Vandalizing or taking resources is prohibited

  34. Special Shoreline Response Issues (continued) • Public Interaction and the Media • Access to shoreline • Adjacent neighbors • Keep a cool head and refer to ICP for comments

  35. Shoreline Response Techniques • Natural recovery (No action) • Manual removal • Sediment removal • Passive collection • Flushing

  36. Shoreline Response Techniques (continued) • Vacuum • Sediment reworking • Excavation, Cleansing, and Replacement • Vegetation cutting • Shoreline treatment (dispersants)

  37. Natural Recovery

  38. Manual Removal

  39. Manual Removal

  40. Operational Effectiveness • Shoreline Types • Exposed rocky shoreline • Wave cut platforms and tidal pools

  41. Operational Effectiveness • Shoreline Types • Gravel beach • Man made shoreline and rip-rap

  42. Operational Effectiveness

  43. Minimizing Environmental Impact

  44. Sediment Removal

  45. Operational Effectiveness • Shoreline Types • Fine Grain Beach • Course Grain Beach • Mixed Sand and Gravel
