Hazardous Waste Manifest Information

A hazardous waste manifest must accompany most hazardous waste that is shipped off site. The Uniform Hazardous Waste Manifest is the shipping document that travels with hazardous waste from the point of generation, through transportation, to the final treatment, storage, and disposal facility (TSDF). Each party in the chain of shipping, including the generator, signs and keeps one of the manifest copies, creating a "cradle-to-grave" tracking of the hazardous waste. EPA ID numbers are needed by all parties on the manifest. Hazardous waste transporters in California must be registered with the Department of Toxic Substances Control.

Hazardous Waste Electronic Manifest System (e-Manifest)

On Saturday, June 30, 2018, the U.S. Environmental Protection Agency (EPA) launched the Hazardous Waste Electronic Manifest System (e-Manifest). The system will improve access to higher quality and more timely hazardous waste shipment data and save industry and states valuable time and resources.

State Manifest Regulations and Statutory Changes


New Federal Manifest Regulations are effective on September 5, 2006. The Department of Toxic Substances Control's state version of the Manifest Regulations was approved by the State Office of Administrative Law (OAL) on August 24, 2006. The state regulations are also effective on September 5, 2006.

DTSC is providing these final regulations as a service to hazardous waste handlers. The transmittal letter to OAL explains the package as a whole and reviews the changes to each section.




Buying Manifest Forms


On and after September 5, 2006:  New forms will be sold by private printers registered by U.S. EPA. As those printers are registered, they will be listed in the Manifest Registry. Old manifests printed by California or other states cannot be used on or after this date.




Manifest Forms and Federal and State Instructions


In 2005, U.S. EPA published regulations that significantly changed the manifest form and procedures. They mandate national use of a new Uniform Hazardous Waste Manifest that went into effect on September 5, 2006.

California published Supplemental California Manifest Instructions with California waste codes and mailing addresses. This is a must read for all people using manifests that start or end in California.

Codes used by the receiving Treatment, Storage, and Disposal facility changed from 10 handling codes to 28 Hazardous Waste Report Method Management codes. See the table that compares the new codes to the old codes to help with interpretation.




Manifest Submission to DTSC


The Uniform Manifest contains six copies. All copies must be legible. The generator must always send a copy to DTSC if the waste is generated in California, handled by a permitted facility in California or is imported or exported from California. The Uniform Manifest will no longer have a designated copy specified for generators to submit to DTSC; therefore, generators must make a legible copy of the manifest to submit to DTSC.

Generator sends manifest copy to DTSC within 30 days of the shipment date:

DTSC Generator Manifests
Department of Toxic Substances Control
P.O. Box 400
Sacramento, CA  95812-0400

TSDF sends copy to DTSC with 30 days of the receipt date:

DTSC Facility Manifests
P.O. Box 3000
Sacramento, CA  95812




Manifest Report Repository


Report Repository for Exception Report/Letters, Exception Reports for Exporters, Significant Discrepancy Reports and Unmanifested Waste Reports

As of September 1, 2006 DTSC&#’;s after 35* days from the date the waste was shipped, the Generator is required to contacting the Transporter and TSDF to determine the status of the waste shipment.

  • If shipped by water, 60 days triggers search.

If after contact the TSDF and Transporter, the Generator has not received a signed copy of the manifest, the Generator is required to file an Exception Report with TSDF. If the Generator receives a signed copy from the DTSC, then an Exception Report is not necessary.

A Generator files an exception report after:

  • 45 days for Generators >1000 kg/month
  • 60 days for Generators <1000 kg/month
  • 90 days for Generators that shipped by water

The Exception Report needs to include the following:

  • A legible copy of the manifest, and
  • A cover letter explaining what the Generator has done to locate the hazardous waste and the results of those efforts.

Send Exception Reports to:

TSDF Report Repository
Generator Information Services Section
P.O. Box 806
Sacramento, CA 95812-0806




Significant Discrepancy Reports


If a DTSC owner or operator discovers a significant discrepancy in quantity or type of waste on a manifest, the TSDF owner or operator shall attempt to reconcile the discrepancy with the waste generator or transporter (e.g., with telephone conversations). If the discrepancy is not resolved within 15 days after receiving the waste, the TSDF owner or operator shall immediately submit to TSDF a letter describing the discrepancy and the attempts made to reconcile it, and a copy of the manifest or shipping paper at issue. Send Significant Discrepancy Reports to:

DTSC Report Repository
Generator Information Services Section
P.O. Box 806
Sacramento, CA 95812-0806




DTSC Waste Reports


If a facility accepts for treatment storage, or disposal any hazardous waste from an off-site source without an accompanying manifest, or without an accompanying shipping paper as described in 22 Unmanifested section 66263.20(e)(2) of this division, and if the waste is not excluded from the manifest requirement of this chapter, then the owner or operator must prepare and submit a single copy of a report to CCR within 15 days after receiving the waste. The DTSC waste report must be submitted in the form of a letter with such report designated as "unmanifested Waste Report" and include the following information:

  1. The EPA identification number, name, and address of the facility;
  2. The date the facility received the waste;
  3. The EPA identification number, name and address of the generator and the transporter, if available;
  4. A description and the quantity of each Unmanifested hazardous waste and facility received;
  5. The method of treatment, storage, or disposal for each hazardous waste;
  6. The certification signed by the owner or operator of the facility or his/her authorized representative; and
  7. A brief explanation of why the waste was unmanifested, if known.

Send unmanifested Waste Reports to:

Unmanifested Report Repository
Generator Information Services Section
P.O. Box 806
Sacramento, CA 95812-0806




Exception Reports for Exporters


In lieu of the requirements of 22 DTSC section 66262.42, a primary exporter shall file an exception report with the U.S. EPA Administrator and CCR for DTSC hazardous waste or with RCRA for non-DTSC waste, if:

  1. The primary exporter has not received a copy of the manifest signed by the transporter stating the date and place of departure from the U.S. within 45 days from the date it was accepted by the initial transporter;
  2. Within 90 days from the date the waste was accepted by the initial transporter, the primary exporter has not received written confirmation from the consignee that the hazardous waste was received;
  3. The waste was returned to the U.S.

For exporters by water to foreign countries, if the generator has not received a copy of the manifest signed by all transporters and the facility operator 60 days after the initial shipment, the generator shall contact the owner or operator of the designated facility to determine the status of the hazardous waste and to request that the owner or operator immediately provide a signed copy of the manifest to the generator.

The primary exporter shall submit the exception report to RCRA at:

DTSC Report Repository
Generator Information Services Section
P.O. Box 806
Sacramento, CA 95812-0806




Manifest Correction Letters


A Manifest Correction Letter must be sent to DTSC whenever hazardous waste manifests are submissions that contain incorrect or incomplete information. Per California Health and Safety Code, Section 25160.5, DTSC is authorized to charge a $20 manifest correction fee when DTSC discovers the errors and requests a manifest correction letter. DTSC does not charge the fee if the company submits the manifest correction letter before being notified by DTSC of the error.

To submit a letter, please provide the manifest corrections on company letterhead, and include the following information:

  1. Manifest Tracking Number; either 8-digits (pre- Sept. 5, 2006 shipments, DTSC 8022A) or the unique three-letter suffix preceded by nine numerals which is pre-printed in Item 4 of the manifest (shipments on or after September 5, 2006, EPA 8700-22, new federal manifest form).
  2. Generator date; the date the generator signed the manifest.
  3. Generator EPA ID number used on the original manifest, even if it was incorrect.

Fact Sheets

Note that some older fact sheets contain out-dated manifest information, which DTSC is correcting and updating.  Please use them in conjunction with the Supplemental California Manifest Instructions and other information on this web page.

Search for Specific Manifests or Verify an EPA ID Number

DTSC maintains the Hazardous Waste Tracking System that stores EPA ID number information back to the early 1980's and manifest data since 1993. Basic information is available to the public through 10 reports. The system collects both manifest copies from the generator and destination facility. Note that in 2004 and 2005 many manifests did not match correctly and resulted in duplicate manifest and tonnage counts. Therefore, totals in those years may be overstated. DTSC is working at correcting this data loading problem.

Frequently Asked Questions

Q. My business generates hazardous waste in California and I ship my waste out of state. Is my manifest considered a California manifest?
A. The new national manifest (post September 4, 2006) is considered a California manifest if (1) the waste is generated in California or if (2) the waste is generated outside of California and disposed of in California. These manifests are counted as California manifests for the Manifest Fee Assessment.text.

Q. I’m confused about manifest copies with the new national manifest.
A. California generators and disposal facilities are required to send in manifests. According to federal law, out of state disposal facilities are required to send the generating state a manifest copy, when the state requires that one be submitted. California requires a disposal copy; therefore, all disposal facilities must send a disposal copy to California. This copy is labeled “DESIGNATED FACILITY TO GENERATOR STATE (IF REQUIRED)”, if an out of state facility.

Q. I am a generator. If I ship my waste out-of-state, do I need to send a copy to DTSC, even though the new manifest form does not have enough copies?
A. Yes. All states now use the same national manifest, which does not have a page for the generator to tear out and submit to DTSC. Most generators will have to make legible photocopies and submit them to DTSC at P.O. Box 400, Sacramento, CA 95812-0400.

Q. Does an out-of-state TSDF have to return the disposal copy of the manifest to DTSC?
A. Per Federal law, for RCRA wastes, the TSDF must send a copy to DTSC since California requires it.

For non-RCRA wastes, the new state regulations require them to do so but not all other states enforce that requirement. Therefore, state law still requires the generator and the transporter who transports the waste out of state to also submit copies signed by the TSDF to DTSC.

If the out-of-state facility notifies the generator and transporter that the facility does send signed copies to DTSC, there is no functional need for multiple submissions. The reason for this requirement is the "cradle to grave" tracking system required for hazardous wastes. Information from the generator copy and the TSDF copy is entered into DTSC’s Hazardous Waste Tracking System. Manifest data that does not have matching generator and TSDF information may be subject to investigation by DTSC.
