The U.S. Department of the Interior (DOI) anticipates proposing a new rule that would revise its “Type A” Natural Resource Damage Assessment (NRDA) regulations under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) in Fall 2023. The proposed rule would modernize DOI’s rarely used simplified Type A procedures for assessing damages for natural resource injuries tailored at sites involving minor releases of hazardous substances, with a smaller scale and scope of natural resource injury occurring in either coastal and marine areas or Great Lakes environments (the “Type A Rule”). (See 88 Fed. Reg. 3373; see 43 C.F.R. Pt. 11 Subpt. D.) The Type A Rule was last updated in 1997.

DOI previewed the proposal in January 2023 in its Office of Restoration and Damage Assessment’s (ORDA) Advanced Notice of Proposed Rulemaking (ANPR). In the ANPR, the ORDA surmised that the Type A Rule was rarely used in part because of its restricted scope, but also because “the model equation for each Type A environment is the functional part of the rule itself—with no provisions to reflect evolving toxicology, ecology, technology, or other scientific understanding without a formal amendment to the Type A Rule each time a parameter is modified.” Calling the existing rule “inefficient and inflexible,” the ORDA stated that its proposal to reformulate the rule “as a procedural structure” would “modernize the Type A process and develop a more flexible and enduring rule than what is provided by the two existing static models” (88 Fed. Reg. 3373).
