It's a new reporting year and time to plan for reporting and compliance deadlines from 2025's activities and for the new year.
It’s a new reporting year and time to plan for reporting and compliance deadlines from 2025’s activities and for the new year.
⚡ TL;DR: 2026 requires EPCRA Tier II submissions (March 1), biennial hazardous waste reports for large generators (March 1), OSHA electronic injury reporting, annual respirator fit-testing, and DOT hazmat registrations. Missing any deadline triggers EPA, OSHA, or DOT enforcement action.
Mark your calendars with these environmental and safety reporting deadlines and other to-do tasks for 2026: > ⚠️ What’s at stake: Missing a single compliance deadline can trigger EPA penalties of $25,000 to $37,500 for EPCRA violations, OSHA fines of $13,000+ for reporting failures, or DOT sanctions preventing hazmat transportation. Accumulating missed deadlines across multiple regulations can result in facility shutdowns and criminal charges.

Frequently Asked Questions
Q: When are EPCRA SARA Tier II reports due in 2026?
EPCRA SARA Tier II reports (Forms 311 and 312) are due by March 1, 2026 (or February 27 if March 1 falls on a weekend). These reports must be submitted to your State Emergency Response Commission and local emergency planning committees and provide information about hazardous chemicals stored at your facility. iSi Environmental helps facilities prepare accurate and timely Tier II submissions to avoid EPA penalties.
Q: What is the deadline for biennial hazardous waste reports?
Large Quantity Generators must submit biennial hazardous waste reports by March 1 in even-numbered years, with the next report due March 1, 2026. These reports must be filed with the EPA or your authorized state environmental agency and must accurately account for all hazardous waste generated and managed during the preceding two-year period. Failure to submit timely biennial reports can result in significant fines and enforcement action.
Q: What training and certifications require annual renewal or periodic recertification under OSHA and DOT?
OSHA requires annual respirator fit-testing, respiratory protection training, and specific safety training in areas like bloodborne pathogens and confined space entry. DOT requires hazmat refresher training every 3 years, while IATA requires hazmat training every 2 years and IMDG every 3 years. iSi Environmental can coordinate comprehensive training schedules to ensure your facility meets all OSHA, DOT, IATA, and IMDG requirements in Kansas and Oklahoma.
Q: Are there state or local compliance deadlines beyond the federal EPA and OSHA deadlines?
Yes, many facilities have additional state and local reporting requirements including Title V air permit certifications, stormwater reports, storage tank registrations, and groundwater monitoring reports. These deadlines vary by state and locality, so facilities in Kansas, Oklahoma, and Texas must verify requirements with their state environmental agencies. iSi Environmental assesses your facility’s specific regulatory obligations to ensure you meet all applicable federal, state, and local deadlines.
💰 The cost of non-compliance: EPCRA Tier II late filing: $25,000+ per violation. Biennial hazardous waste report violations: $37,500 fine per day. OSHA electronic reporting failures: $13,000+ per violation. Missing DOT registrations: $2,600+ annual penalty plus transportation prohibition.
