Applicant's summary and conclusion

Conclusions:
The half-life of 5-hydroxyisopthalic acid in soil is 720 hrs (30 days). Thus, 5-hydroxyisopthalic acid is not expected to bepersistent in soil as it does not exceeds the threshold criteria (60 days) for being categorized as persistent and shall bio-degrade in the soil.
Executive summary:
