What it does
This bill exempts small oil and gas wells (producing 15 barrels of oil per day or less, or 90,000 cubic feet of natural gas per day or less) from federal Clean Air Act emissions standards, monitoring, and leak-detection requirements. It also prevents states from imposing their own standards on these wells and automatically approves state plan revisions that remove marginal-well regulations within 180 days.
Why we flagged it
The bill's core function is to remove federal and state-level emissions standards and monitoring requirements for small oil and gas producers. Despite the 'small business' framing, it is fundamentally a deregulatory measure that exempts a large class of wells from Clean Air Act oversight.
What the text implies
- Aggregate exemption: while individual 'marginal wells' are small, thousands exist nationwide; the cumulative methane and VOC emissions from all exempted wells may be substantial, but will no longer be tracked or reported.
- State preemption: the bill prevents states from setting their own standards on marginal wells, removing a key regulatory backstop and limiting state-level environmental authority.
