Waste Characteristics

The algorithm for combining the values for the most hazardous substance with the value for hazardous waste quantity for the surface water pathway should already be familiar:
- Ecotoxicity times persistence times quantity capped at 10⁸. Then the BPFV is brought in and the product capped at 10¹². The maximum score for waste characteristics from HRS Table 2-7 on page 51592 is now 1,000, not 100.
When hazardous waste quanitity is at its maximum value of 1,000,000, be aware that two substances with the same most hazardous value of 5 x 10⁶ may trigger different values for waste characteristics because of the impact of the 10⁸ cap in the calculation. This point was discussed at the end of Section 13.2 of this course.
