Waste Management and Safety

It is a discarded commercial chemical product, off-specification species,

container residue, or spill residue of materials specifically listed in

40 CFR 261.33 (P- and U-codes);

It is a waste from a specific source listed in 40 CFR 261.32 (K-code);

261.33. These codes are provided to help you identify hazardous waste. The

generator is responsible for making the actual waste code determination.

Selected characteristic waste codes for chemicals which may be generated using

Hach methods for water analysis are given in the following table. A complete list

of waste codes is found in 40 CFR 261.20 through 40 CFR 261.33.

Federal laws do not require you to test a material to decide if it is a hazardous
