Managing Hazardous Waste

We strengthen regulations and streamline waste management

Managing Asbestos Waste Fact Sheet

December 2006*

Regulatory Assistance Officer’s Note

The Regulatory Assistance Officers of the Department of Toxic Substances Control (DTSC) prepared this fact sheet to provide general information about the hazardous waste requirements associated with generating, transporting and disposing of asbestos waste. In addition, several other sources of information about asbestos and asbestos handling appear at the end of the fact sheet. Throughout this fact sheet are citations from Title 22, California Code of Regulations (Cal. Code Reg., title 22), the California Health and Safety Code (Health and Safe. Code). There are also citations from the Code of Federal Regulations (CFR): Title 29 for Department of Labor, Title 40 for EPA (RCRA), and Title 49 for Department of Transportation. Clicking on the section number links will take you to internet sites containing those regulations. If you generate hazardous waste, you should consult with your Certified Unified Program Agency (CUPA). Finally, DTSC strongly encourages all businesses generating hazardous waste to consider waste minimization, source reduction and pollution prevention. Go to the Duty Officer FAQs for useful links.

What is Asbestos and How Dangerous is it?

Asbestos refers to a family of fibrous minerals found all over world and in the serpentine rock that occurs throughout California. When the fibers break off and become airborne, they can create a health risk if inhaled. Asbestos exposure is associated with certain types of lung cancer, and long time occupational exposure can also cause the lung disease asbestosis. Read more about the health risks of asbestos in the California Department of Public Health publication “FAQs about Asbestos in the Home and Workplace” (opens new window). In the past, asbestos was used in many household products and building materials because of its heat-resistant and structural properties. As a result, building remodeling and demolition projects produce much of the asbestos waste we see today. DTSC regulates the packaging, onsite accumulation, transportation, and disposal of asbestos when it is a hazardous waste, as defined below. Other agencies, listed at the end of this fact sheet, regulate asbestos abatement, as well as activities related to naturally-occurring asbestos.

Do I Have to Manage Asbestos as a Hazardous Waste?

DTSC classifies asbestos-containing material as hazardous waste if it is “friable” and contains one percent (1.0%) or more asbestos as hazardous waste. A friable waste is one that can be reduced to a powder or dust under hand pressure when dry. This classification standard is given in California Code of Regulations, section 66261.24 (opens new window). Because the United States Environmental Protection Agency (U.S. EPA) does not regulate asbestos as hazardous waste under the Resource Conservation and Recovery Act (RCRA), it is considered to be a “non-RCRA,” or “California-only” hazardous waste. However, various state and federal regulations address other aspects of asbestos management, such as asbestos abatement (see Referrals at the end of this fact sheet.).

DTSC considers non-friable bulk asbestos-containing waste to be non-hazardous regardless of its asbestos content, so it is not subject to regulation under Title 22, Division 4.5, of the California Code of Regulations (opens new window). Again, other regulatory agencies operating under separate authority have their own requirements or restrictions.

How do I Determine Whether my Asbestos Waste must be Handled as a Hazardous Waste?

If you are not certain whether your asbestos waste is hazardous, you must have it tested (Cal. Code Regs., title 22, section (66262.11(b)(2)) (opens new window) by a laboratory certified by the California Department of Health Services, Environmental Laboratory Accreditation Program. The lab will determine the percentage of friable asbestos in the material. Check in the phone book for “Laboratories, Analytical” or “Asbestos Abatement and Removal Services.” Your local Air Quality Management District or Air Pollution Control District may also have a list of laboratories in your area. The cost for bulk asbestos testing varies significantly, depending primarily on the analytical method used, the type of sampling that is required and who collects the samples.

How Must Hazardous Waste Asbestos be Packaged?

Asbestos is an airborne hazard, so the rules and regulations that describe the proper handling and packaging of asbestos are found in Federal and State air quality regulations. The packaging required by in those regulations satisfies those of DTSC. Check with your local air pollution control district to see if there are additional packaging requirements for your region.

At a minimum, you must contain and transport it in one of the following ways:

  • In sealed, leak-tight, non-returnable containers (e.g., plastic bags of at least 6-mil thickness, cartons, drums, or cans) from which the fibers cannot escape. Additionally, you must wet the wastes to prevent fibers from blowing around in the event that the container is broken. 40 CFR 61.150, (opens new window) or;
  • For bulk waste that will not fit into such containers without additional breaking, wet it to prevent blowing of fibers in case the wrapping is broken, then wrap it so it will be leak-tight and seal it with packaging or duct tape.
  • If you are placing the wrapped and sealed waste directly in trailers or drop-boxes, you need to line the container with plastic sheeting and covered it with a tarp. (Cal. Code Regs., title 13, section 66263.23.)

Wetting asbestos waste does not constitute treatment, so you do not need to obtain special authorization to do so.

How do I Label the Properly Packaged Asbestos?

Each asbestos package or container must have a caution label affixed to the outside. That label must be conspicuous and contain legible lettering that spells the following warning: (29 C.F.R. §1910.1001 (j)(2) and 1926.1101(k)(8), and Cal. Code Reg., title 8, § 5208(j)(5)).

Avoid Creating Dust

Cancer and Lung Disease Hazard

In addition to this warning requirement, California Code of Regulations, title 22, section 66262.32 requires that hazardous waste containers with a capacity of 110 gallons or less be marked with the following words and information in accordance with the requirements of 49 Code of Federal Regulations section 172.304:

Hazardous Waste – State and Federal Law Prohibit Improper Disposal. If found, contact the nearest police or public safety authority or the California Department of Toxic Substances Control.

Are there Different Requirements for Transporting Different Amounts of Hazardous Asbestos Waste?

Yes. If you have more than 50 pounds of any hazardous waste, including asbestos, you must use a registered hazardous waste transporter to take the wastes to a permitted treatment, storage, or disposal facility and the waste must be accompanied by a hazardous waste manifest (shipping paper).

Persons who transport less than 50 pounds of household hazardous waste to a household hazardous waste collection event or disposal facility may do so in any safe manner. Businesses may transport less than 50 pounds of hazardous waste to a permitted facility if they meet all of the following conditions: Health and Safety Code section 25163(c) (opens new window).

You must transport the waste in closed containers that are packed in a manner that prevents tipping, spilling, or breaking during transport.

You may not mix different hazardous wastes in one container during transportation.

You must have generated the waste that you are transporting, your hazardous waste generation rate is not greater than 100 kilograms (220 pounds) per month, and you accumulate no more than 1,000 kilograms (2200 pounds) at your business at any one time.

Please note that many household hazardous waste programs do not accept asbestos waste. Contact your local environmental health department to see whether such service is available in your community.

In addition, you must place the proper U.S. Department of Transportation (DOT) (opens new window) shipping name and identification number on all hazardous material containers of 110 gallons or less capacity. For asbestos, the entry is:

RQ, Asbestos, 9, NA2212, III

This is the same shipping name and identification number that must appear on the manifest (if used). For more information see 49 Code of Federal Regulations section 172.301. You are not required to placard transport vehicles carrying hazardous materials (such as asbestos wastes) which are classed as “Other Regulated Material” (ORM).

For further information regarding DOT requirements, visit its website; the Hazardous Materials Transportation Guides (opens new window) are particularly useful. Or contact the U.S. Department of Transportation, Office of Motor Carrier Safety at:

Northern California
Sacramento. – (916) 498-5050,

Southern California
Moreno Valley – (909) 653-2299

The Motor Carrier Safety Unit of the California Highway Patrol Office nearest you also has information (see the State Government section of white pages in your local telephone directory).

How do I Get a California Generator ID Number?

The DTSC Fact Sheet, “EPA Identification Numbers,” tells you about both federal (U. S. EPA) and state ID numbers. If you do not routinely generate hazardous waste, but are generating hazardous waste (including asbestos) as a result of remodeling or asbestos abatement work, you can get a one-time temporary ID number. Asbestos wastes that have been generated by residential renovation can use a special number. An ID number can be assigned over the telephone; contact DTSC’s Generator Information Services Section at (800) 618-6942 (or 61TOXIC), or at (916) 255-1136.

Are there Special Disposal Requirements for Asbestos?

Yes. As mentioned previously, wetting and double bagging is required for many types of asbestos waste. Asbestos wastes must be handled and disposed of in accordance with the federal Toxic Substances Control Act, 40 CFR 763 (opens new window). Other applicable laws and regulations include the Clean Air Act (NESHAP) (opens new window), and California Code of Regulations, title 22, division 4.5 (opens new window). The U.S. EPA website has a number of references to asbestos disposal requirements.

A landfill must be authorized to accept asbestos wastes by its Regional Water Quality Control Board. Many municipal landfills and demolition debris landfills are permitted to accept asbestos wastes. Call your Regional Board to see if they have a list of the asbestos-accepting landfills in your area. Your local Air Quality Management District may also have a list. Before you take asbestos to a landfill, call them to find out whether you need an appointment or whether they have any special requirements.

Is LDR Notification Required for Out-Of-State Shipments of Non-RCRA Waste such as Asbestos-Containing Wastes?

Generators that are using a one-time residential or 90-day provisional EPA ID number for asbestos waste disposal are not required to submit land disposal restriction (LDR) notifications and certifications. Other generators of friable asbestos waste who have handled and packaged their waste for disposal are required to submit California land disposal notification and certification per California Code of Regulations, title 22, section 66268.7(a)(11) (opens new window).

If you have further questions regarding LDR requirements for asbestos waste, feel free to contact your DTSC Regulatory Assistance Officer.

Do I Have to Pay the State a Special Fee to Dispose of Asbestos Waste?

The disposal facility pays the fee if the generator disposes of 500 pounds or less of hazardous waste during the year. Generators who dispose of more than 500 pounds of waste per year to land pay a quarterly or semi-annual Hazardous Waste Control Account (HWCA) land disposal fee.

If the disposal involves more than 500 pounds, the manifest should include the generator’s Board of Equalization taxpayer number (listed in Section “B” of the manifest, i.e., under State required items in the shaded portion). A Board of Equalization taxpayer number can be obtained from the Board by calling (800) 400-7115, (916) 322-9534. Additional information on current hazardous waste fees and taxes can be obtained from the Board of Equalization at these same numbers, or from the DTSC at (916) 322-8676.

Finally, California law imposes a fee on generators of five tons or more of hazardous waste per site per year, regardless of disposition. The fee is payable by the generator, who is billed annually by the Board of Equalization.

Are there Other Agencies that Regulate Asbestos Activities?

Yes. Some key agencies are listed below:

Other sources of information and assistance include:

  • Agency for Toxic Substances and Disease Registry (ATSDR) (opens new window): This Federal Agency has information and guidance relating to asbestos and many other hazardous substances.
  • Consumer Product Safety Commission (opens new window):  They have information about identifying and abating asbestos hazards in the home. Information on asbestos in certain consumer products is also available. Visit their Contacts/FAQ (opens new window) page for more information.
