Medical Waste Manifest Guide for California Generators
How medical waste manifests work in California, required fields, retention rules, and the cradle-to-grave responsibilities every generator has.
Medical waste manifests are the legal documentation that proves your facility complied with California's cradle-to-grave waste handling requirements. They follow each shipment from your facility through the transporter to the treatment facility, with signatures from each party.
This guide covers the required manifest fields, how the manifesting process works in California, retention rules, and what generators need to do if a manifest doesn't get closed properly.
Required Manifest Fields
- Generator name, address, and CDPH registration number
- Transporter name, registration number, and signature
- Treatment or destination facility name, EPA ID, and signature on receipt
- Date of pickup and date of delivery
- Description and weight of waste by category (biohazardous, sharps, pathological, pharmaceutical)
- Container count and container size per category
- Special handling instructions (chemo, controlled substances, etc.)
- Manifest tracking number unique to the shipment
Five Steps in the Manifest Lifecycle
Generator initiates manifest
When waste is ready for pickup, the generator pre-populates the manifest with facility info, waste categories, weights, and container counts. Most providers do this in their online dashboard.
Transporter picks up + signs
BAC's hazmat-trained driver verifies the waste, signs the manifest, and provides the generator copy. The original travels with the waste.
Treatment facility receives + signs
On arrival at the treatment facility, an authorized signatory weighs and inspects the waste, signs the manifest confirming receipt, and uploads the closed manifest to the e-Manifest system.
Generator retains copy 3+ years
California Title 17 CCR 118000 requires retention for at least 3 years. Best practice: retain indefinitely given environmental statutes of limitations.
BAC posts the Certificate of Treatment
Within 7 business days, the Certificate of Treatment and Recovery appears in your NETZERO|360 dashboard, cross-referenced to the manifest number.
Digital manifests + Certificate of Treatment in NETZERO|360
Every BAC shipment generates a digitally-signed manifest cross-referenced to a Certificate of Treatment and Recovery, all stored and downloadable from your NETZERO|360 dashboard.

A medical waste manifest is the legal chain-of-custody document that follows a shipment from generator through transporter to the treatment facility. It documents who handled the waste, when, what waste streams were included, and proves proper disposal.
Federal e-Manifest applies primarily to RCRA hazardous waste. California medical waste manifests are CDPH-administered, often handled through provider dashboards. Many providers (including BAC) generate electronic manifests that integrate with the federal e-Manifest where dual-classified hazardous streams are included.
California Title 17 CCR 118000 requires retention for at least 3 years from the date of shipment. Federal RCRA also requires 3 years for hazardous waste manifests. Best practice is to retain indefinitely given the long statute of limitations on environmental claims.
Under the cradle-to-grave principle, you (the generator) remain legally responsible until the manifest is closed by an authorized signatory at the treatment facility. If 35 days pass without a closed manifest, the generator must submit an Exception Report to CDPH explaining the gap.
Under H&SC 25115 cradle-to-grave principles, the generator remains responsible for the waste from generation through final treatment. If the transporter mishandles, the generator can face cleanup liability. This is why selecting a registered, insured, and reputable transporter matters.
Yes. All BAC manifests are digitally generated, signed by hazmat-trained drivers, and uploaded to the NETZERO|360 dashboard cross-referenced with the federal e-Manifest where applicable. You can download manifests in PDF or CSV format for retention and audit.
