Pathway Score

Each pathway score is based on the product of three "factor categories" that are multiplied and normalized to a pathway score of 0 to 100.

Likelihood of Release X Waste Characteristics X Targets divided by 82,500

The scaling factor of 82, 500 results in a pathway score of 100 when the three factor categories are at their maximum or "reasonable worst case" values of 550, 100, and 150.

550 X 100 X 150 divided by 82,500 = 100
