2 June 11, 2010 ~ 9:50 pm pipeline located in Red Butte Canyon ruptured. June 12, 2010 SLVHD was notified at 7:15 am oil was flowing in Red Butte Creek. The SLC Fire Dept was on scene and had dispatched a crew upstream from there to find the source of the oil. At about 7:30 am, the pipeline rupture was discovered in Red Butte Garden. The oil flowed down Red Butte Creek, through residential area, into Liberty Park pond and the Jordan River. 800 barrels or 33,000 gallons of crude oil was released into the soil and into Red Butte Creek.

4 What Happened? Investigation by DOT revealed a high voltage arc from a 135 kv power transmission line traveled underground to a fence post which was resting on top of the pipeline (36 inches below ground) and blew a dime-sized hole in the pipeline. The line was releasing crude oil at the ~ rate of gal/min for 10 hours before the leak was discovered.

14 What is SCAT Assessment Shoreline Cleanup Assessment Team Identifies areas with oiled vegetation, sheen, stain, and odor Used to prioritize cleanup Get proper resources to cleanup area

15 SCAT evaluations following flushes reveal many hot spots remain along stream corridor. A crew in A-1 removing brush for SCAT teams found a badly decomposed corpse in stream. Concerts at Red Butte Garden Amphitheater continue during response and remediation Accommodations being made for Garden Park Ward Weddings to be relocated

20 Unified Command & NIMS/ICS Initial disorganization and independent actions Initial UC meeting on 3 rd day of incident Who was involved in initial response? Who had jurisdiction for ongoing oversight and enforcement of CPL after initial response phase? Who should have been involved and which entities have a place in UC during an incident? What is the role of the LNO and how should various minor stakeholders be informed by the UC members? How effective is UC in directing PRP response actions?

21 Legal Authorities Legal Authorities National Oil and Hazardous Substances Pollution Contingency Plan (NCP) Oil Pollution Act (OPA) Endangered Species Act (ESA) State Statutes? City and Public Health Statutes? Agencies with Jurisdiction Federal EPA, USF&W, USACE State UDEQ (DWQ, DERR & DAQ?) & UDNR (DWRe & DWR) Local Salt Lake City (Public Utilities, EM & Environmental) Regional Salt Lake Valley Health Department Rights of Property Owners Access and Easements

24 Data Management What was sampled? What needed to be sampled? Sample coordination Who does what? Data gaps Start with the end in mind Action levels -- What do you do with the data? Sharing Data and Information

25 Could this happen again? Most Pipeline damage is caused by digging.

26 Could this happen in your city?

27 Red Butte #2 A second spill (about 75 yards from the original spill) About 500 barrels released into the amphitheater and neighboring grounds.

29 Cause It is believed to have been caused by freezing water left in the pipeline at a valve box during the pressure test conducted earlier this year. 250 barrels valve box

40 Product Characterization Sample collected and sent to Coast Guard Lab Product characterization not timely Product characterization protocol different than all subsequent analyses How do we use the data? Subsequent attempts to recreate the information

41 On-Going Complaints

42 Red Butte Monitoring Locations 3 control site locations 2 sites below in stream Both storm drains before entering the Jordan

43 Water Monitoring Constituents of Interest Laboratory Selection Detection Limits Data Interpretation Data Sharing Cost Considerations

44 Groundwater Monitoring Sampled wells and springs Analyzed for hydrocarbon compounds, for comparison to drinking water standards Sampling frequency adjusted based on travel times Groundwater monitoring will continue for years

46 Aquatic Macroinvertebrate Monitoring Health of the Stream IDEAL INDICATORS: Highly diverse community Fulfill part or entire life cycle in water Sensitive to stressors Easily collected and identified

48 Take Home Points - Monitoring WHO? Determine Monitoring Group WHAT? What media need to be sampled? Why? WHERE? WHEN? HOW? Line Up Resources Sampling Locations? Sampling Frequency? Bottles? Lab? Analytical Methods & Detection Limits? Availability of Crew? Public Involvement?

49 Data Sharing Web Page Press Releases Public Meetings

50 Lessons Learned Communication #1 priority in disaster response UC should have been established Day 1 Davis County involvement from beginning Practice practice practice IC concepts Redundancy in staffing necessary Technical expertise early (booms/dams)

51 Messaging Keep It Simple Communicate Keep boots on the ground informed Commitments Lessons Learned UC means informing all parties prior to media interviews and press releases Air monitoring capabilities by regulatory agencies and started earlier along corridor.

52 Lessons Learned Large events tie up resources Cleanup companies not available for other spills Large events take large amounts of space Liberty Park U of U Parking Lot Broaden UC updates Include other agencies (Flood Control, Davis County, etc.)

53 What went well? Chevron response impressive with massive allocation of resources/manpower Once established, Unified Command worked cooperatively and efficiently Agencies working hand in hand with Chevron personnel on SCAT and hot spot evaluations /clean up operations EPA as a resource invaluable
