EPA’s 2026 regulatory shift: How environmental managers can stay ahead
The clock is ticking for environmental teams. By 2026, several new EPA regulations will reshape compliance obligations for U.S. companies. Organizations that act now will avoid costly penalties and operational disruptions.
What’s changing and why it matters
Although EPA has been deregulating or loosening some requirements, there are still some standards being tightened across multiple fronts in the coming year:
- Renewable fuel standards (RFS): The EPA proposed higher volume requirements for 2026, including 24.02 billion renewable identification numbers (RINs), up nearly 8% from 2025. This increase pushes stricter expectations on fuel producers and organizations purchasing renewable fuels.
- Stormwater multi-sector general permit (MSGP): A new MSGP set to take effect by February 2026 will require quarterly PFAS indicator monitoring, expanded benchmark sampling, and resiliency measures in stormwater control designs.
- PFAS Reporting under the Toxic Substances Control Act (TSCA): TSCA Section 8(a)(7) mandates PFAS manufacturing and import data collection beginning in April 2026, through October 2026, with extended deadlines for certain small manufacturers.
Failure to prepare could lead to fines, reputational damage, supply chain disruptions, and permit delays. Companies that weave compliance planning into their 2026 strategy will be positioned not just to meet legal deadlines but to sustain operations smoothly.
Key areas of impact
- Renewable fuel standards (RFS) and air emissions The proposed increase in 2026 Renewable Identification Numbers (RIN) volumes, from 24.02 billion to 24.46 billion for 2027, signals tightening air and fuels policy that affects fuel use and emissions accounting.
- Stormwater management The upcoming 2026 MSGP requires expanded quarterly PFAS monitoring, new benchmark triggers, corrective action plans, and integration of climate resilience in design standards.
- PFAS disclosure (TSCA Section 8(a)(7)) Manufacturers and importers of PFAS must submit electronic reporting of usage, volumes, disposal, and exposure data between April and October 2026, with extensions available for smaller operations.
Steps to take now
- Audit compliance programs: Cross-check operations against RIN inventory, stormwater permits, and TSCA reporting duties.
- Upgrade monitoring and recordkeeping: Implement robust electronic systems to track PFAS, stormwater quality, fuel volumes, and emissions.
- Staff training: Educate teams on PFAS obligations, new stormwater protocols, and RFS structures.
- Engage regulators early: Comment on proposed rules, consult during permit drafting, and flag issues during the notice-and-comment period.
Looking ahead
The EPA’s 2026 updates reflect a trend toward increased transparency and environmental accountability. Companies that treat compliance as strategic will not only avoid enforcement but also gain resilience and stakeholder trust.
Key to remember: Start planning now. Early action on EPA rule changes will save time, money, and headaches when enforcement begins.
