EPA Revises PVC Factory Rules, Easing Wastewater Limits While Keeping Air Controls
Published Date: 11/9/2026
Rule
Summary
The EPA just updated rules for new big factories making PVC and copolymers. They removed some strict limits and paperwork for certain wastewater pollution but kept strong controls on vinyl chloride emissions. These changes start right away on November 9, 2026, helping companies save time and money while still protecting the air.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
New PVC Plants: Wastewater HAP Limit Removed
If you build a new major polyvinyl chloride (PVC) or copolymer production facility, EPA removed the numeric limit for total non-vinyl chloride organic hazardous air pollutants (HAP) in process wastewater and removed the related testing, monitoring, recordkeeping, and reporting requirements. The EPA estimates this change would save a new major source about $2,900 in capital/startup costs and about $30,000 in annual costs (all in 2025 dollars).
Focus on Vinyl Chloride as Wastewater Surrogate
EPA finalized that the existing new-source vinyl chloride process-wastewater limit (0.28 parts per million by weight (ppmw)) will act as a surrogate for other non-vinyl chloride organic HAP in process wastewater for new major PVC and copolymer sources. That means new major sources need to meet the 0.28 ppmw vinyl chloride limit rather than separate numeric limits for many other organic HAP in wastewater.

2026-22082, Additional Reconsideration Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review
The EPA is updating rules for oil and natural gas companies to fix issues from last year’s changes. They’re scrapping the Super Emitter Program, splitting well sites into clearer groups, and tweaking rules on leaks, equipment, and inspections. Companies should get ready to comment by December 16, 2026, as these updates could affect how they manage emissions and operate equipment.
2026-21155, Renewable Fuel Standard (RFS) Program: Reallocation of Additional 2025 Small Refinery Exemptions
The EPA is updating how it handles small refinery exemptions (SREs) for 2025 under the Renewable Fuel Standard. They’re deciding whether to spread the extra exemptions between 2026 and 2027 or give them all to 2027. This change might also push back the 2026 compliance deadline, affecting refiners and renewable fuel producers with potential timing and cost impacts.
2026-20849, Clean Water Act Hazardous Substance Facility Response Plans: Compliance Date Delay and Changes To Reflect Administration Policy
The EPA is giving facilities more time to meet new Clean Water Act rules for handling hazardous spills, pushing back the deadline to help them get ready. They’re also removing mentions of climate change and environmental justice to match new government policies. This delay helps facilities plan better without rushing and lets the EPA rethink the rules if needed.
2026-19071, Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units
The EPA is rolling back most of the 2024 rules that limited carbon pollution from fossil fuel power plants. This change affects coal and gas plants by easing some strict limits on emissions and carbon capture technology. The new rules kick in on November 16, 2026, potentially saving money for power plants but raising questions about pollution control.
2026-19072, Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111
The EPA is proposing to cancel all greenhouse gas rules for fossil fuel power plants, saying the law doesn’t let them regulate these emissions for climate reasons. This change affects power plants across the U.S. and could impact future pollution limits and costs. Comments on this proposal are open until November 2, 2026, so now’s the time to speak up!
2026-18317, Updated Definition of “Waters of the United States”
The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.
