  2. Gilco Transport • April 9th, 2010 • Tanker overturns at MP 220 on US 6 • Hairpin corner directly above A-Basin base area. • Comes to rest on a retaining wall above a 1,000 foot 1:1 slope. • Approx 2,280 gallons of red-dye diesel fuel released. • Approx 4,700 gallons of fuel were off-loaded into another tanker. • Some fuel did reach the North Fork of the Snake River

  3. Bioremediaton agents Recurring issue for Region 8 RRT Use on or near water requires federal approval Micoblaze/Biosolve/etc RRT elected to conduct a study to evaluate claims Clean Water Act field order: protections to be put in place an assessment of the slope and USFS access road below the spill Evaluation of microbial agents on the slope at altitude. Spill of Opportunity

  4. Up to 4 agents vs natural and augmented attenuation Microblaze and BioSolve chosen for evaluation Augmented attenuation reduced contaminants the most Other agents did not live up to manufacturer claims… Microbial Evaluation

  5. Agent Application • August 2010 • Should be effective for top 3-6 inches of soil

  6. Current Situation • Work shut down for the winter • Pass is closed today due to snow… • Last samples show an average contamination reduction of 32% • USFS Concerns: • remaining contamination on the slope over the winter • effectiveness/timeliness of the bio-remediation effort

  7. Next Steps • RP contractor will monitor the spill area during the Spring run-off • If discharge is discovered, boom will be deployed • Second round of bio-remediation treatment planned - June 2011 • Inject to 6-12 inches or to refusal • Nutrients, oxygen at depth
