Per the requirements in EPA Rule Procedures for Prioritization of Chemicals for Risk Evaluation Under the Toxic Substances Control Act, initiate prioritization to evaluate whether hydrofluoric acid is a High-Priority Substance for risk evaluation. If it is determined to be a High-Priority Substance, conduct a risk evaluation of hydrofluoric acid to determine whether it presents an unreasonable risk of injury to health or the environment. If it is determined to present an unreasonable risk of injury to health or the environment, apply requirements to hydrofluoric acid to the extent necessary to eliminate or significantly mitigate the risk, for example by using a methodology such as the hierarchy of controls.


Status: Closed - Reconsidered/Superseded
Closed - Reconsidered/Superseded (C - R/S) - Recipient rejects the recommendation and also supports the rejection with a rationale with which the Board concurs. This designation may apply when later facts indicate that the concerns expressed in the recommendation were actually addressed prior to the incident, or when a recommendation is superseded by a new, more appropriate recommendation.
