If your facility still treats hazardous waste manifesting as a paper-and-filing-cabinet process, 2025 changed the ground under you. As of January 22, 2025, every Large and Small Quantity Generator must be registered in EPA's e-Manifest system — and as of December 1, 2025, key manifest-related reports must be filed electronically, not mailed. Here's what actually changed, what's still allowed, and where facilities are getting caught.
What changed on January 22, 2025
The e-Manifest "Third Rule" took effect, and two pieces matter most to generators:
- Mandatory registration. Every LQG and SQG must now be registered in EPA's e-Manifest system through the RCRAInfo portal, with at least one person authorized to sign and submit. This applies whether or not you file electronically. A facility that isn't registered cannot legally initiate a hazardous waste shipment.
- No more mailed-back paper copies. TSDFs are no longer required to mail you a signed paper return copy. Your signed manifests live in your e-Manifest account — which means if you're not logging in and reconciling, you may not know whether your waste reached its destination.
What changed on December 1, 2025
The second wave of the Third Rule went live. The manifest-related reports that generators previously mailed to EPA or a state agency must now be submitted through the e-Manifest system:
- Exception Reports — filed when you don't receive a signed return manifest in time.
- Discrepancy Reports — filed when waste received doesn't match the manifest.
- Unmanifested Waste Reports — filed when waste arrives without a manifest.
Paper submissions of these reports are no longer accepted. For many facilities this is the quiet trap: they have a process for mailing an exception report and no process at all for filing one electronically.
The EPA portal vs. a system that files for you
Registering for e-Manifest gets you a government submission interface. It does not track your accumulation clocks, warn you before a reporting deadline, pre-fill a manifest from your last shipment, or assemble your audit package when an inspector arrives. It handles one step. The rest of the compliance workflow is still on you.
That's the gap enviro.lytics is built to close: build a waste profile once, and every future manifest for that stream pre-fills and files directly to EPA's CDX — with the accumulation clocks, follow-up tracking, and recordkeeping handled around it.
What to do now
- Confirm your facility is registered in RCRAInfo with at least one authorized signer.
- Make sure someone logs in regularly to retrieve signed manifests — they no longer arrive in the mail.
- Establish a process for filing Exception, Discrepancy, and Unmanifested Waste Reports electronically.
Bottom line
The mandate didn't outlaw paper overnight, but it moved the system of record online and put the burden of monitoring on you. Facilities still relying on the mailbox are the ones most exposed.
