Any stationary facility storing 10,000 lbs or more of propane across one or multiple co-located tanks must file a Risk Management Plan (RMP) with the EPA. Retail sites (≥50 % revenue from end-user sales) and on-site fuel-use tanks are exempt. US EPA

Program 1 vs. Program 3 – Know Your Tier
• Program 1: Simple storage with no public receptors inside the worst-case 1 psi over-pressure zone; requires a brief worst-case analysis and certification.
• Program 3: Bulk terminals and wholesalers near public receptors; mandates a full Process Safety Management–style Prevention Program and detailed Emergency Response Plan.

Key Compliance Steps
1 Compile Process Safety Information (tank specs, relief-valve data).
2 Conduct release-scenario modeling (see Appendix B equations).
3 File or update the RMP electronically via EPA’s CDX portal.
4 Review NFPA 58 alignment; most elements overlap, streamlining compliance.

Conclusion
Following EPA propane-storage guidance avoids costly violations and strengthens public safety. Contact INGUSA Group, we offer ASME-certified tanks.
