Applicant's summary and conclusion
- Conclusions:
- The Level III Fugacity model contained within EPISuite v4.0 gives the following estimates regarding the distribution and half life of the test material in the following media:
Air: mass amount: 44.1 %, half life = 218 hr, emissions = 1000 kg/hr
Water: mass amount: 45.7 %, half life = 360 hr, emissions = 1000 kg/hr
Soil: mass amount: 10.1 %, half life = 720 hr, emissions = 1000 kg/hr
Sediment: mass amount: 0.159 %, half life = 3.24 x 10^3 hr, emissions = 0 kg/hr
Overall Persistence time = 138 hr - Executive summary:
