Miscellaneous
Dust collected by a baghouse
Fabric-filter air-pollution equipment collected the hazardous dust or residue.
Is California code 591 hazardous waste?
Not from the code alone. First decide the material is hazardous. Code 591 isn't restricted, so a restricted category that fits wins over it. A non-restricted code doesn't make a waste nonhazardous.
If a shipment needs the Uniform Hazardous Waste Manifest, enter 591 in Item 13 for its waste line. Use one California code, plus the federal RCRA codes when the waste is federally hazardous.
RCRA waste meets a federal listing or characteristic and has no federal exclusion. Non-RCRA waste is hazardous under California rules only. California presumes hazardous waste is RCRA unless the generator shows it isn't, so keep that record.
What does California code 591 cover?
This entry is hazardous dust caught when a baghouse passes a gas stream through fabric filters. It depends on that equipment. Dust from another control device, or residue formed directly by combustion, needs its own assessment of where it came from.
