From page 57...
... Different transportation practices also have different potentials for routine and accidental releases. The single and most relevant piece of information in evaluating toxic chemical management practices is the annual quantity of specific chemicals transported across facility boundaries.

... This type of information is not provided through TRI reporting requirements and also would not be provided through the addition al reporting of any type of mass balance information. The use of mass balance information collected within a facility can support chemical management practices that reduce the presence of toxic chemicals on site.

From page 59...
... CONCLUSIONS EMB and MA are conceptually useful for assessing and sometimes improving management practices, including transportation of toxic chemicals into and out of a facility, storage, tracking toxic chemicals on site, waste reduction, and waste treatment. However, mass balance information obtained either through EMB or MA practice is generally inappropriate from a practical perspective.

... facilities. Information currently reported to the TRI does not closely link release data to chemical-management practices except for on-site waste-treatment practices.
