Applicant's summary and conclusion

Executive summary:

For trimethylolpropane, the percent distribution were calculated with the Level III Fugacity Model of EPIWIN 3.2 to be: air 0.316 %, water 39.9%, soil 59.7% and sediment 0.073.

Due to the scarce information to the model and to the used values, the reliability may not be assessed.
