Reportable release time period

Over what time period must a Reportable Quantity (RQ) of a hazardous substance be released for that release to be reportable?

EPA has stated that the period during which the person in charge must measure whether an RQ or more has been released is 24 hours. Reporting must occur immediately upon knowledge of the release.
