What must be done within 24 hours of confirming a leak in a UST?

When a leak in a Underground Storage Tank (UST) is confirmed, it is crucial to notify the Pennsylvania Department of Environmental Protection (DEP) within 24 hours and take immediate action to mitigate the release. This requirement is part of the regulatory framework established to protect public health and the environment from the hazardous effects of leaking petroleum products and other hazardous substances.

Prompt notification allows the DEP to provide guidance, assess the situation, and ensure that appropriate measures are taken to contain and remediate the leak. Immediate action may include steps such as stopping the leak, controlling the spread of the contaminant, implementing temporary measures to protect health and safety, and deploying spill response resources. This response not only minimizes potential environmental damage but also plays a critical role in safeguarding the community and nearby ecosystems from the risks associated with harmful substances.

Taking measures only like sealing the tank or monitoring for further leaks, reporting to local authorities without involving the DEP, or immediately replacing the UST may not adequately address the urgent environmental and health risks posed by the leak, nor would they fulfill regulatory obligations. Engaging with the DEP ensures that proper protocols are followed in line with state regulations regarding UST management and leak response.
