MSHA Retires Underground Coal Mines’ Long-Forgotten Foam Generators
Published Date: 11/12/2026
Rule
Summary
MSHA is clearing out old rules about foam generator systems in underground coal mines because these systems are outdated and no longer used. This change affects coal mine operators by removing confusing, unnecessary requirements without cutting any safety protections. The new rule kicks in on December 14, 2026, making mine safety rules simpler and easier to follow.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Remove foam-system installation rule
MSHA is removing 30 CFR 75.1101-5, the rule that described how to install fixed automatic foam generator systems in underground coal mines. The change is effective December 14, 2026, and MSHA says foam generator systems are no longer used because water deluge fire-suppression systems are as effective and easier to maintain; removing the section will simplify rules and will not impose new costs on coal mine operators.
Miner safety protections preserved
MSHA states that removing Sec. 75.1101-5 will not reduce protections afforded to miners. The final rule keeps existing mine safety protections in place while streamlining regulatory text, effective December 14, 2026.
