Detailed Verified Answers
A large quantity generator of hazardous waste has a tank used to
store hazardous waste pending transportation off-site and
subsequent disposal. When employees arrive on-site on Monday
morning, they notice that the tank contains less liquid than it
should, and it has been determined that the tank is leaking
hazardous waste into the ground underneath. How quickly must
the facility owner or operator verbally notify their regional
administrator or EPA of this release?
A. Within 8 hours of detection
B. Within the same business day of detection
C. Within 24 hours of detection
D. Within 30 days of detection
⼀Answer:- C. Within 24 hours of detection
40 CFR §265.196 states that verbal notification to their regional
administrator or EPA must occur within 24 hours of detection; if the
release involves a release of a hazardous substance exceeding the
RQ, notification to the National Response Center will meet this
reporting requirement.
