Notes:
Table A-2 lists the soil COPCs for Zone 10. Detected COPCs in the upper 2 ft of soil in the Settling Pit area are included in this risk driver analysis.
a
  RBSVSoil obtained from 30 TAC 335 Subchapter S. The residential PRG was derived from the EPA PRG calculator located at http://www.epa.gov/super
b
    The risk ratio for each COPC is a unitless value derived by dividing the maximum detected concentration by the corresponding RBSV Soil or the Residenti
c
    Total risk ratio is equal to the sum of all individual risk ratios.
d
    % Contribution to the total risk ratio for each COPC is equal to the risk ratio divided by the total risk ratio, then multiplied by 100.
