Gridlock vs. Growth: Deep Divide in Congress Over Clean Air Act Reform

The chairman of the Environment Subcommittee of Congress’ Energy and Commerce Committee wasted no time laying out the stakes at a September 16, 2025, hearing titled, “From Gridlock to Growth: Permitting Reform Under the Clean Air Act.”

“If we want to remain globally competitive, we need meaningful permitting reform,” said Rep. Gary Palmer (R-Ala.) to kick off the subcommittee hearing. “This cannot happen without modernizing the Clean Air Act.”

The hearing reignited a long-standing discussion over how to balance industrial growth with public health protections. It also highlighted a divide in how lawmakers, regulators, and stakeholders view the future of Clean Air Act permitting. While Republicans and industry leaders described the proposed reforms as vital to boosting economic growth, energy reliability, national security, and technological innovation, critics warned that weaker oversight could undo decades of progress on clean air and public health.

New Source Review at Issue

At the center of the debate was the Clean Air Act’s pre-construction air permits program (called New Source Review (NSR)), a regulatory process that requires industrial facilities to obtain approval before constructing or modifying operations that could increase emissions. These permits are designed to make sure that new emissions do not worsen local air quality or break federal health standards, especially in overburdened communities already impacted by pollution. For decades, this permitting program has been a key tool for supporting the broader goal of the Clean Air Act: safeguarding public health and the environment.

Lawmakers reviewed five Republican-sponsored proposals aimed at streamlining that process. These included efforts to overhaul the New Source Review Improvement Act, ease permitting for national security-related projects, and limit how certain air quality data (such as pollution from wildfires or extreme weather) is used in permitting decisions.
