The actions described below are designed to minimize the seriousness
of a hazardous materials incident, should one occur on your premises.
These requirements apply to all generators of hazardous waste with
some exceptions. Small Quantity Generators of less than 1000 kg of
hazardous waste per month may, in some cases, store their hazardous
waste longer than 90 days.
At a minimum, you will need to ensure that
hazardous wastes are:
- Stored in
structurally sound tanks or containers in good condition
with tight-fitting lids.
- Are kept closed when
wastes are not being added or removed.
labeled with water-proof stickers. Labels must specify the
words "Hazardous Waste"; the composition and
physical state of the waste; the hazardous properties of the
waste (e.g., flammable, reactive, etc.); and the name and
address of the generator.
- Labeled with the date
that the waste accumulation began on each tank or container.
This date is the date waste is first placed into the
container or tank.
- Handled in tanks or containers
in good repair. These tanks and containers must be regularly
inspected for deterioration, damage or leaks.
- Managed in a way that minimizes the possibility of
spills and escape of waste into the environment.
- Incompatible waste: not stored in a common storage area
without proper separation. Used oil may not be mixed with
any other hazardous waste (e.g., solvents).
- Ignitable or reactive waste: Stored at least 15 meters
(50 ft.) from property lines (this only applies to large
quantity generators of hazardous waste). Ignitable waste
must be grounded when material is being added or removed.
Contact the fire department in your jurisdiction to learn
about their local requirements regarding handling of
- Stored onsite according to
storage time limits prescribed in the regulations. Storage
times vary depending on the monthly generation rate of
hazardous waste throughout the entire facility. Generators
may store hazardous wastes onsite for 90 or 180 days
depending on the volume of waste produced. In some cases the
wastes may be stored for up to 270 days if the offsite
treatment, disposal, or storage facility is more than 200

- Generators of hazardous waste who will exceed
the storage maximum must apply for permit from the State
Department of Toxic Substances Control (714) 484-5300.
Additional conditions and requirements apply to those
- Generators, which generate no
more than 100 kg exclusively of silver-only hazardous waste

Exempt Small Quantity Generator (CESQG)
Waste Labeling |
Generators that accumulate and store
hazardous waste on-site must comply with the following
labeling requirements. The containers, including
portable tanks, must be properly labeled with the
information listed below:
- The words:
- Name and
address of the facility generating the waste
- Waste accumulation start date (when the waste
started to collect in the container?)
- Physical state (solid or liquid?)
- Composition (what is it?)
Classification (e.g. flammable, toxic, corrosive,
