| Fish LC50 data must be derived from an exposure
period greater than or equal to 24 hours. A
hierarchy of species LC50 data should be used that
includes (in decreasing order of preference) salmonids
(including trout), fathead minnows, and other fish
species. |

Biological
Test Methods |
| Bioassay Testing on either laboratory fish or rats. |
| Bioassay or biological testing can be done on a
representative sample of a waste with unknown
components, Biological test methods are referenced in
WAC 173-303-110(3)(b)
|
| The actual test methods are described in
Biological
Testing Methods 80-12 for the Designation of Dangerous
Waste, Ecology publication #80-12, revised
June 2009. The test methods were developed by Ecology to meet the designation
requirements of Dangerous Waste Toxic Criteria under
WAC 173-303-100(5)(c)
|
Chemical Test Methods |
| Chemical testing can be done on a representative
sample of a suspected dangerous waste with unknown
components. Chemical test methods are referenced in
WAC
173-303-110 (3)(c)
|
| The actual test methods are described in
Chemical
Testing Methods for Designating Dangerous Waste,
Ecology publication #97-407, revised June
2009. |
| Test methods referenced in Chemical Testing Methods
are from: |
| Test methods referenced are for designation of the
dangerous waste: Characteristics
- Ignitability
- Corrosivity
- Reactivity
- Toxicity characteristic leaching procedure (TCLP)
Persistence Criteria
- Halogenated organic compounds including PCBs.
- Polycyclic aromatic hydrocarbons.

| Refer to Chemical Testing Methods for Designating
Dangerous Waste, for a more complete discussion of
the above methods. |

Using
Knowledge Instead of Testing |
| Two ways to designate a dangerous waste are given in
the Dangerous Waste Regulations,
Chapter 173-303 WAC,
Section -070(3)(c). The designator can either "apply
their knowledge of the waste in light of the materials
or the process used," or "test the waste." |
| Knowledge alone can be enough to designate a waste.
Knowledge about a waste also limits the number of tests
that might be done. |
| Refer to
Designation Using Knowledge for more
information. |
