To determine natural resource damages for purposes of an action under OSPRA, the General Land Office (GLO) may use the natural resource damages assessment methods adopted pursuant to Chapter 20 of this title (relating to Natural Resource Damage Assessment) or the methods by the United States Department of Interior under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (42 United States Code §1321 et seq.), or by the United States Department of Commerce under OPA. The GLO may use any reliable methods of assessment that it deems reasonable given the particular resources affected.
