43 CFR 11.14 (ss)

"Type A assessment means standard procedures for simplified assessments requiring minimal field observation to determine damages as specified in section 301(c)(2)(A) of CERCLA."

Type A Assessments are available only for minor spills in coastal areas or the Great Lakes. Type A Assessments use the Natural Resource Damage Assessment Model for Coastal and Marine Environments or for Great Lakes Environments (NRDAM/CME or NRDAM/GLE; 43 CFR 11.40-.44). The models each have 4 submodels: physical fates, biological effects, restoration, and compensable value. The models:

• Determine biological injury through the interaction of physical fates and biological effects submodels;

• Quantify injury through the biological effects submodel;

• Select and cost out appropriate restoration actions; and

• Calculate certain categories of public economic values lost pending recovery of the injured resources.
