These civil penalty increases stem from the Federal Civil Penalties Inflation Adjustment Act Improvements Act of 2015, which mandated that federal agencies make annual adjustments to the civil monetary penalties they administer, following a specified procedure and formula. The 2015 Act significantly increased the amount of annual penalty adjustments by tying those adjustments to changes in the consumer price index.

The civil penalty amounts are in effect for all penalties assessed on or after December 27, 2023 (for EPA violations) or December 28, 2023 (for DOT/NHTSA violations). All penalties increased by a factor of 1.03241. Below is a summary of the key violations/series of violations for which the maximum penalty is significantly higher than in 2023.
