  • Mixing Oil and Historic Structures: Hazards and Response
    By Mary F. Striegel
  • ===== Act I
  • The Deepwater Horizon explosion led to the largest accidental marine oil spill in the history of the petroleum industry.

  • In addition to our natural resources, cultural heritage sites were threatened with oil contamination.
  • NCPTT Serves as a Center of Technical Expertise for the National Park Service.
  • NCPTT was created by Congress to develop or transfer new technologies to the world of historic preservation.
  • Without solid information on appropriate response to an oil spill, more damages to cultural heritage can occur.

  • Better scientific understanding can lead to smarter response for cultural heritage threatened by an oil spill.
  • ===== Act II, Scene 1
  • Considering the possibilities…

  • Types of Cultural Heritage at Risk.
  • Oil Spill Contamination.

  • Evaluating Risks of Oil to Materials.

  • Preventing contamination.

  • ===== Act II, Scene 2
  • Documenting the Contamination.
  • Gather Information in a Uniform Way.
  • Record Location Data.
    Follow Cultural Resources
    GIS recommendations:
    • Trimble Model GeoXT, GeoXM or GeoXH
    • Accuracy of +/- 3 meters or better.
    • NAD83 datum.
    • Export GPS data into GIS shape files.
    • Map each site or standing structure as a point;
    • Map the property as a boundary or building footprint.
  • Photograph the extent of oil impact.

  • Collect oil samples.
  • ===== Act II, Scene 3
  • Investigating ways to “restore” cultural heritage.
  • EPA National Contingency Plan.
    • Schedule of Products considered as safer oil spill treatments
    • “Lift and Float” Products
    • Release of treatments into the waterways
    • Oil spill treatment still must be approved
  • Cleaners for brick masonry.
  • Cleaners for shell and bone.
  • Other Considerations…
  • Becoming Part of the Team.
  • ===== Act III
  • Will research open the door to better response for future oil spills?
  • The technical information is needed before the disaster strikes.
  • Better scientific understanding can learn to smarter response for cultural heritage threatened by an oil spill.
  • NCPTT is working to build the needed technical knowledge for better disaster response.
