On March 11, 2024, the U.S. Environmental Protection Agency (EPA) published the much-anticipated Safer Communities by Chemical Accident Prevention Rule (SCCAP) Final Rule, an update to EPA’s Risk Management Program (RMP) 40 CFR Part 68, under the Clean Air Act Amendments of 1990 (CAA). This is the first substantial change to the rule since its inception in 1996.

In developing a 70 megapascal (MPa) fueling infrastructure, it is critical to ensure that a vehicle equipped with a lower service pressure fuel tank is never filled from a 70 MPa fueling source. Filling of a lower service pressure vehicle at a 70 MPa fueling source is likely to result in a catastrophic event with severe injuries or fatalities. The Hydrogen Safety Panel recommends that DOE undertake a two‐step process to address this issue.
