Red Butte Creek Oil Spill

......


The Utah Department of Health partnered with the Salt Lake Valley Health Department and Salt Lake City to determine possible health issues relating to crude oil exposure from the Red Butte Creek Oil Spill in June 2010. All findings were published in a public health assessment and a subsequent health consultation, both produced through a cooperative agreement with ATSDR (Agency for Toxic Substance and Disease Registry) and made available to the public through this website.

 

  • Public Health Assessment (PHA)
    • The PHA evaluates the potential for long-term health impacts in the community from exposure to components of crude oil. It also addresses the crude oil contaminants and the environmental compartments that were impacted during the spill, specifically focusing on water and air.
    • Based upon the available data regarding air and water contamination of the Red Butte Creek due to the Chevron oil spill, the EEP finds NO immediate health hazard to the community.
      • Based upon EEPs review of the Red Butte Creek surface water and air data, as well as community concerns, the following actions are recommended:
        • The cancer incidence study specific for cancer types linked to crude oil exposure should be
          re-evaluated every five years, as additional cancer data becomes available.
        • Coordination with the Utah Department of Environmental Quality (UDEQ) will continue to
          assess future sampling data during the remediation process, including flush events.
        • Based upon the available data regarding air and water contamination of the Red Butte
          Creek due to the Chevron oil spill, the EEP found NO immediate health hazard to the
          community due to VOC exposure.

     

  • Health Consultation (HC)
    • This document is an extension of the PHA and addresses community concerns regarding exposures to polycyclic aromatic hydrocarbons (PAHs) in the water and creek soil sediment.
    • Based upon the available data regarding water and soil contamination of the Red Butte
      Creek due to the Chevron oil spill, the EEP found NO apparent health hazard to the
      community due to PAH exposure.
      • Based upon EEPs review of the Red Butte Creek surface water and air data, as well as community concerns, the following actions are recommended:
        • The cancer incidence study specific for cancer types linked to crude oil exposure be re-evaluated every five years, as additional data becomes available.
        • Coordinate with UDEQ to assess future sampling data to better guide further remediation if it is deemed necessary.
