CHMM - Bowen EHS Questions || with 100% Correct 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 correct answers 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.
