HRS rule, page 51620, all of Section 4.1.3.3.1

4.1.3.3.1 Food chain individual.

Evaluate the food chain individual factor based on the fisheries (or portions of fisheries) within the target distance limit for the watershed. Assign this factor a value as follows:

  • If any fishery (or portion of a fishery) is subject to Level I concentrations, assign a value of 50.

  • If not, but if any fishery (or portion of a fishery) is subject to Level II concentrations, assign a value of 45.

  • If not, but there is an observed release of a hazardous substance having a bioaccumulation potential factor value of 500 or greater to surface water in the watershed and there is a fishery (or portion of a fishery) present anywhere within the target distance limit, assign a value of 20.

  • If there is no observed release to surface water in the watershed or there is no observed release of a hazardous substance having a bioaccumulation potential factor value of 500 or greater but there is a fishery (or poriton of a fishery) present anywhere within the target distance limit, assign a value as follows:

    • Using Table 4-13, determine the highest dilution weight (that is, lowest amount of dilution) applicable to the fisheries (or portions of fisheries) within the target distance limit. Multiply this dilution weight by 20 and round to the nearest integer.

    • Assign this calculated value as the factor value.

  • If there are no fisheries (or portions of fisheries) within the target distance limit of the watershed, assign a vlue of 0.

    Enter the value assigned in Table 4-1.
