How quickly must suspected releases be investigated?

Suspected releases from underground storage tanks (USTs) must be investigated within two days because this timeframe is established to ensure prompt action to protect public health and the environment. Investigating suspected releases quickly helps to assess potential risks, prevent further contamination, and initiate remediation activities if necessary. Timely investigation is crucial, as delays could result in increased environmental damage, more complicated remediation efforts, and higher costs. By adhering to this two-day requirement, operators can effectively manage the integrity of their storage systems and comply with regulatory standards designed to protect community safety.
