### Applicant's summary and conclusion

Conclusions:
The Mackay Level III equilibrium model estimates that Alcohols, C11-14-iso, C13-rich will partition largely to the soil compartment (approximately 77%), followed by the water (approximately 21%) and minimally to the air and sediment compartments (1.5 and 0.44%, respectively), based on all available measured data.
