Summary: | Critical subset allocation (CSA) is a methodology for allocating remediation costs at sites where multiple contaminants contribute to the exceedance of multiple regulatory risk standards. The basic unit of allocation in CSA is the critical subset, which is a subset of potentially responsible parties (PRPs) that meets two criteria: 1) the risks associated with the subset exceed at least one regulatory risk standard; and 2) at least one of the PRPs in the subset is individually necessary for the first criterion to be true. Each PRP is assigned an allocation score equal to the number of critical subsets for which that PRP is an individually necessary member. The allocation share of a PRP is equal to its allocation score divided by the sum of all PRP allocation scores. |
