from WAC 173-303-9904
The Dangerous Waste Sources list is divided into two parts, Generic Sources and Specific Sources.
Generic Sources:
The "F" codes identify generic wastes that are produced by a variety of industrial operations. F code wastes from used products should have accompanying MSDS information and labels. F code solvents are used in some paint stripping products.
The description of the Generic or Non-specific sources generally includes the word "spent":
"Spent material," means any material that has been used and as a result of contamination can no longer serve the purpose for which it was produced without processing (WAC 173-303-040 Exit Ecology).
A listed generic ingredient in a waste is not necessarily a spent ingredient. For example, xylene as an ingredient in a can of paint is not considered "spent". A rag with xylene used to wipe paint (or grease) off a part would be "spent".
Mixtures: If a listed source waste is mixed with an otherwise non-dangerous solid waste then the entire mixture becomes a dangerous waste source and is given the F, K or W number of the source.
The hazard codes following the source description are used to indicate the basis EPA used for listing the classes or types of wastes listed.

Footnote 2. Listing Specific Definitions:
a. For the purposes of the F037 and F038 listings, oil/water/solids is defined as oil and/or water and/or solids.
b. (i). For the purposes of the F037 and F038 listings, aggressive biological treatment units are defined as units which employ one of the following four treatment methods: Activated sludge; trickling filter; rotating biological contactor for the continuous accelerated biological oxidation of wastewaters; or high-rate aeration. Highrate aeration is a system of surface impoundments or tanks, in which intense mechanical aeration is used to completely mix the wastes, enhance biological activity, and
(ii). Generators and treatment, storage and disposal facilities have the burden of proving that their sludges are exempt from listing as F037 and F038 wastes under this definition. Generators and treatment, storage and disposal facilities must maintain, in their operating or other on-site records, documents and data sufficient to prove that:
- The unit is an aggressive biological treatment unit as defined in this subsection; and
- the sludges sought to be exempted from the definitions of F037 and/or F038 were actually treated in the aggressive biological treatment unit.
c. (i). For the purposes of the F037 listing, sludges are considered to be generated at the moment of deposition in the unit, where deposition is defined as at least a temporary cessation of lateral particle movement.
(ii). For the purposes of the F038 listing,
A. Sludges are considered to be generated at the moment of deposition in the unit, where deposition is defined as at least a temporary cessation of lateral particle movement and
B. Floats are considered to be generated at the moment they are formed in the top of the unit.
