Discarded Chemical Products Definition
(for U and P codes)

 from WAC 173-303-081

Last updated 11/06/07

Does the waste meet the definition in WAC 173-303-081 Exit Ecology of an unused commercial chemical product, manufacturing chemical intermediate or a spill cleanup from an unused product?

"Commercial chemical product or manufacturing chemical intermediate" refers to a chemical substance which is manufactured or formulated for commercial or manufacturing use which consists of:

1. the commercially pure grade of the chemical,
2. any technical grades of the chemical that are produced or marketed, and
3. all formulations in which the chemical is the sole active ingredient. (WAC 173-303-040 Exit Ecology

The commercial chemical product or manufacturing chemical intermediate may be:

1. an on-specification grade or formulation, or
2. an off- specification grade or formulation which would be listed in WAC 173-303-9903 Exit Ecology if it were on specification, or
3. any containers, inner liners or residue remaining in a container or inner liner that has held (a) or (b) unless the containers or inner liners meet the definition of empty in WAC 173-303-160 (2) Exit Ecology, ("P" containers must also be triple rinsed), or
4. any residue of contaminated soil, water or other debris resulting from the cleanup of a spill of (a) or (b). (WAC 173-303-081 Exit Ecology)

P or U  wastes can have only one active ingredient. Water, alcohol, oil or other materials may be mixed with an active ingredient for dilution, handling safety or some other purpose - pesticides are good examples. These ingredients are not considered "active" for designation purposes.

Mixtures: If a waste that designates as a discarded chemical product is mixed with an otherwise non-dangerous solid waste then the entire mixture designates as a discarded chemical product and is given the P or U number of the product.

Normally a waste could not designate on both the discarded chemical products list and the sources list. An exception could happen if someone mixed a U or P waste with an F waste. The resulting mixture would have both sets of waste codes and would be more difficult to dispose.
