Contact Congress about H.R. 161: New Source Review Permitting Improvement Act

Large plants and factories could make some upgrades without going through New Source Review. The bill narrows when a project counts as a change that raises pollution enough to trigger that permit process.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

New Source Review Permitting Improvement Act is a House bill waiting for floor action. The latest recorded action: Placed on the Union Calendar, Calendar No. 542.

Latest action on H.R. 161: Placed on the Union Calendar, Calendar No. 542.

Who this affects: This bill mainly affects large plants, factories, and other fixed sources of air pollution that want to repair, upgrade, expand, or modernize equipment. It also affects the Environmental Protection Agency and state air regulators, who decide when Clean Air Act permits are needed. Communities near major facilities could be affected if fewer projects go through permit review and pollution controls.

Why this matters: The bill matters because it could change which plant projects get a pollution permit review before work starts. Some companies may find it easier to repair or upgrade old equipment. Nearby communities may have fewer review points where regulators can require updated pollution controls. The bill’s real effect is uncertain because it depends on how many projects avoid review and how the Environmental Protection Agency applies the tests.

Key provisions in H.R. 161

  • A project would count as raising emissions only if it raises the source’s maximum hourly pollution rate. The bill compares the new rate with the highest hourly rate the source could reach during any hour in the past 10 years.
  • Some cleaner or safer projects would not count as modifications. This covers projects that cut pollution per unit made or improve safety or reliability, unless they raise hourly emissions and the Environmental Protection Agency finds health or environmental harm.
  • In cleaner areas, the permit trigger would focus on building the actual pollution-making parts. Other site work would not count just because it is large, costly, permanent, or changes the site.
  • For cleaner areas, a modification would count as construction only when it significantly raises yearly actual emissions. The same applies when the net increase is significant at a major emitting facility.
  • In polluted areas that miss air quality standards, the bill uses the same core definition of modification from section 111 of the Clean Air Act. It excludes changes at major facilities that do not significantly raise yearly actual emissions, either directly or on net.

  • Contact your reps on Exemptions for cleaner-per-unit, safety, and reliability projectsWhether projects that improve safety, reliability, or pollution per unit of output should generally avoid Clean Air Act modification review, and when EPA should still be able to require review because total pollution or health risks increase.
  • Contact your reps on What facility changes trigger Clean Air Act reviewWhether factories, power plants, and other fixed sources should need Clean Air Act modification or preconstruction review only when changes significantly increase actual emissions or physically build pollution-emitting equipment.
