3.  To know how long we’re allowed to store hazardous wastes before the RCRA time limits for storage expire.

4.  False. A facility retains liability for any hazardous waste it generates, even if it’s properly disposed of in a RCRA-permitted hazardous waste disposal facility.

5.  True. Large quantity generators can only store wastes for 90 days. Small quantity generators get 180 days to store hazardous wastes. Conditional exempt small quantity generators can store wastes longer than 180 days.

6.  E -- all of the above

7.  False. Solvents and other materials that have hazardous characteristics are only considered hazardous wastes when they can no longer be used and are discarded.

8.  The four characteristics of a hazardous waste are: ignitability, corrosivity, reactivity,
and toxicity.

9.  True, but relying on process knowledge alone is risky. EPA strongly recommends that facilities test materials to see if they exhibit any hazardous characteristics. Companies will be fined for making honest mistakes of overlooking a hazardous component.

10.  Labels are needed to:
1) identify the type of hazardous waste inside,
2) track how long a waste has been stored, and
3) prohibit mixing incompatible wastes.
