HRS Rule, Section 2.4.3, page 51592

2.4.3:Waste characteristics factor category value. Determine the waste characteristics factor category value as specified in section 2.4.3.1 for all pathways and threats, except the surface water-human food chain threat and the surface water- environmental threat. Determine the waste characteristics factor category value for these latter two threats as specified in section 2.4.3.2.

2.4.3.1:Factor category value. For the pathway (or threat) being evaluated, multiply the toxicity or combined factor value, as appropriate, from section 2.4.1.2 and the hazardous waste quantity factor value from section 2.4.2.2, subject to a maximum product of 1 x 108 . Based on this waste characteristics product, assign a waste characteristics factor category value to the pathway (or threat) from Table 2-7.


Table 2-7.
Waste Characteristics Factor Category Values
Waste characteristics product Assigned value
 
0 0
Greater than 0 to less than 10 1
10 to less than 1 x 102 2
1 x 102  to less than 1 x 103 3
1 x 103   to less than 1 x 104 6
1 x 104  to less than 1 x 105 10
1 x 105   to less than 1 x 106 18
1 x 106  to less than 1 x 107 32
1 x 107  to less than 1 x 108 56
1 x 108  to less than 1 x 109 100
1 x 109   to less than 1 x 1010 180
1 x 1010  to less than 1 x 1011 320
1 x 1011  to less than 1 x 1012 560
1 x 1012 1,000

2.4.3.2:Factor category value, considering bioaccumulation potential. For the surface water-human food chain threat and the surface water-environmental threat, multiply the toxicity or combined factor value, as appropriate, from section 2.4.1.2 and the hazardous waste quantity factor value from section 2.4.2.2, subject to:

  • A maximum product of 1 x 1012 , and

  • A maximum product exclusive of the bioaccumulation (or ecosystem bioaccumulation) potential factor of 1 x 108.

Based on the total waste characteristics product, assign a waste characteristics factor category value to these threats from Table 2-7.
