# §990.52. Injury assessment—quantification.

- (a) **General.** In addition to determining whether injuries have resulted from the incident, trustees must quantify the degree, and spatial and temporal extent of such injuries relative to baseline.
- (b) **Quantification approaches.** Trustees may quantify injuries in terms of:
  - (1) The degree, and spatial and temporal extent of the injury to a natural resource;
  - (2) The degree, and spatial and temporal extent of injury to a natural resource, with subsequent translation of that adverse change to a reduction in services provided by the natural resource; or
  - (3) **The amount of services lost as a result of the incident.**
- (c) **Natural recovery.** To quantify injury, trustees must estimate, quantitatively or qualitatively, the time for natural recovery without restoration, but including any response actions. The analysis of natural recovery may consider such factors as:
  - (1) The nature, degree, and spatial and temporal extent of injury;
  - (2) The sensitivity and vulnerability of the injured natural resource and/or service;
  - (3) The reproductive and recruitment potential;
  - (4) The resistance and resilience (stability) of the affected environment;
  - (5) The natural variability; and
  - (6) **The physical/chemical processes of the affected environment.**
