The HWIR QuestionThe HWIR Question

At what constituent concentration will wastes, when placed in non-hazardous waste management units over the unit’s life, result in:

1) greater than A% of the people living within B distance of the facility experiencing a

risk/hazard of C or less and

2) greater than D% of the habitats within E distance of the facility with an ecological hazard less than F, at G% of facilities nationwide?

Where to get 3MRA software EPA CEAM site

How to enable 3MRA to run with FRAMES 2.0 Copy hwirio.dll from FRAMES 2.0 subdirectory to c:\3mra Copy import.0.hdssf to c:\3MRA\ssf for convenience

How to import a 3MRA simulation into FRAMES 2.0 Use the 3MRA import tool

What is produced by 3MRA models. Example output from Site Visualization processor

15

Copy HWIRIO.dll to c:\3mraCopy 3mra\import.0.hdssf to c:\3mra\ssf for convenience

18

The original SUI is presented but the underlying reading/writing is FRAMES 2.0

19

Choose hdtest.ssf. If not available type in hdtest.ssf. Only hdtest.ssf will work for the filename.

20

Use 0114001, Benzene, WP, CW=4 for speed sake. Any should work

21

Make sure you are only running one realization for speed sake

22

Pressing start will generate the case

23

Bring up the FRAMES simulation editor

24

Open the sim from the c:\3mra\ssf directory. Movement to FRAMESV2 is probably better.

25

FRAMESV2 now has the CSM drawn for you. The Simulation is ready to Go.

26

After waiting a little bit, the simulation comes back all green.File->Save to write the data to the files.
