How to Complete and Submit DTSC Form 1358: Hazardous Waste ID Application

DTSC Form 1358 is California’s Permanent State ID Number Application, used by hazardous waste handlers to request a new state identification number from the Department of Toxic Substances Control or to update, reactivate, or inactivate an existing one. There is no fee, and DTSC processes complete applications within 15 business days of receipt.¹

Is Form 1358 the Right Application for You

California requires anyone who generates, transports, treats, stores, or disposes of hazardous waste to hold a hazardous waste identification number before shipping or receiving that waste.² Whether that number comes from the state or from EPA depends on how much federally regulated waste you produce.

Form 1358 is for handlers who generate less than 220 pounds (100 kilograms) of RCRA hazardous waste per month and less than 2.2 pounds (1 kilogram) of RCRA acutely hazardous waste per month, or who generate any amount of non-RCRA hazardous waste.¹ California regulates many waste streams the federal RCRA program does not, so a business can handle no federally listed waste at all and still need a state ID.

Two situations call for a different process. If your facility produces 220 pounds or more of RCRA hazardous waste per month, you need a federal EPA ID number through EPA’s myRCRAid tool, not Form 1358.³ If you only handle hazardous waste on a one-time or infrequent basis, you need a temporary state ID (valid 90 days) through a separate online application rather than this form.⁴

Completing the Form

Download the current PDF from the DTSC website at dtsc.ca.gov/wp-content/uploads/sites/31/2018/06/GISS_FORM_1358.pdf and read the instructions page first. DTSC rejects incomplete or inaccurate applications outright, so there is no partial credit for getting most of it right.¹ The form has 13 lines.

New Number or Change to an Existing One

Line 1 is for new permanent state ID numbers. Check whether you are applying as a generator, a transporter, or both, then select the reason: never had a number, business moved, or the legal business owner changed.

If you already have a state ID and just need to modify it, skip Line 1. Lines 2 through 5 cover updating mailing or contact information, inactivating a number, reactivating a previously inactive one, and changing the business name without an ownership change. When modifying an existing number, enter the full ID number, lettered prefix included, in the space provided.¹

Facility and Business Information

Lines 6 through 12 collect your facility’s identifying details.

Line 6 asks for the site or facility name including any DBA, plus the business type: sole proprietor, corporation, partnership, LLC, or other.
Line 7 is the site location. It must be a physical street address, not a P.O. box. If no physical address exists, DTSC will accept latitude and longitude coordinates or an assessor’s parcel number.
Line 8 is for tax and filing numbers. Enter your Federal Employer Identification Number. Sole proprietors without a FEIN should write “sole proprietorship” or “N/A.” Provide your California Secretary of State filing or entity number and your CDTFA account number if applicable.
Line 9 is the mailing address. A complete address is required; writing “same as above” will get the application rejected.
Line 10 is the site contact: name, address, phone, and business email of a person at the site.
Line 11 is the legal business owner’s name and principal address. For corporations, use the company’s legal name, and match the principal address on file with the California Secretary of State.
Line 12 is the four-digit Standard Industrial Classification code that best describes your primary business activity.

Line 13 is the certification. The signer certifies under penalty of law that the information is true, accurate, and complete. The form requires a handwritten signature. Typed and electronic signatures are not accepted.¹

Submitting the Completed Form

DTSC accepts the signed form through three channels. Email is the recommended method because it gives you a trackable record of delivery.¹

Email (recommended): IDNumber@dtsc.ca.gov
Postal mail: Department of Toxic Substances Control, OEIM – Business Operations Unit, 11th Floor, P.O. Box 806, Sacramento, CA 95812-0806
Fax: (916) 323-3500

DTSC does not confirm receipt of mailed or faxed applications. If you use mail or fax, keep a copy of the signed form along with your proof of mailing or fax confirmation sheet. There is no application fee.⁵

Household hazardous waste collection programs follow a slight variation. If you need an HHW ID number, complete Form 1358 and email it to idnumber@dtsc.ca.gov with “Household Hazardous Waste Request” in the subject line.³

After You Submit

DTSC’s processing time is up to 15 business days from the date it receives your application.¹ You can verify your ID number status through the Hazardous Waste Tracking System at hwts.dtsc.ca.gov, DTSC’s data repository for manifest and ID number information.⁶ Confirm the update before you ship or receive waste under a new or changed number. Manifests referencing an ID that is not yet active can be flagged or rejected.

Why Accuracy on the First Try Matters

Getting the form right the first time has real financial stakes. Under California Health and Safety Code Section 25189.2, making a false statement in a manifest, application, or other compliance document can result in a civil penalty of up to $70,000 per violation, with continuing violations assessed per day.⁷ The same ceiling applies to violations of Chapter 6.5 of the Health and Safety Code, the state’s entire hazardous waste management framework. A rejected application that delays your ID number can also leave you generating or shipping waste without valid identification, which is itself a violation. Read the instructions, double-check every line against your corporate records before signing, and keep proof of what you submitted.
