Hazardous Waste Generator Requirements 425
ash generated from the combustion of coal or other fossil fuels is excluded from being
defined as a hazardous waste.
The following solid wastes are not hazardous wastes:
Fly ash waste, bottom ash waste, slag waste, and flue gas emission control waste, generated pri-
marily from the combustion of coal or other fossil fuels, except as provided by Section 266.112
of this chapter for facilities that burn or process hazardous waste.
13. Unfortunately, there is no simple method to determine if Cr wastes were deep-well
injected; the claim by the inspector would be difficult to prove. Corroboration by a
plant employee or witnesses would have been extremely useful. This case is still under
investigation.
14. Since the container has never been opened, it is considered an unused commercial chem-
ical product. Picric acid is not, however, a U- or P-listed hazardous waste. During pro-
longed periods of storage, picric acid can form picrate salts, which are highly sensitive
to shock and are explosive. As a result, such a waste is considered a characteristic reac-
tive waste and must be handled with utmost care. It would be wise to contact the local
emergency response team for support in handling and disposing of this container.
15. If the TCE solvent was never removed from the system before it was reused, it is not a
“waste.” In the current situation, however, the solvent is reclaimed (treated) before reuse
and is therefore considered a solid waste. Based on the listing procedure, this solid waste
is an F001 waste. The facility must manage their waste stream, including requirements
for generators (counting, manifesting, and so on), according to the requirements of 40
CFR 262.
16. (a) Containers must be covered at all times. Openings in the covers allowed for rainfall
to enter. The covers were not pulled tight; as a result, rain accumulated on the surface,
causing the covers to collapse, thus letting in more water.
(b) The puddles under the roll-off are stained and may contain some of the released
wastes. If the inspector is suspicious of a leak, he should require this facility to conduct
a waste determination.
A facility must be managed to minimize the possibility of a release to the environment.
