Assessment Planning

During this step, the trustees decide on the assessment procedures to be used. The CERCLA NRDAR regulations include both a simplified method, called Type A assessments, and protocols for conducting assessments in individual cases, called Type B assessments. The OPA NRDAR regulations do not identify specific assessment procedures for trustees to use; instead, procedures must meet broad criteria contained in the regulations (15 CFR § 990.27(a)).

An Assessment Study Plan is written that summarizes the PAS (location, resources, potentially responsible parties, etc.) and identifies method(s), sample location, numbers, QA/QC, etc. to confirm pathway, and confirm and quantify exposure and injury (and data sharing, if appropriate). In addition, the trustees evaluate the costs of assessment; they must be reasonable. Draft Assessment Plans are put out for a 30-day public comment period.
