What must an operator do when evidence of a release is found?

When evidence of a release is found, it is crucial for the operator to notify the Department of Environmental Conservation (DEC) and conduct a site assessment. This immediate notification is mandated by regulations to ensure the proper authorities are informed and can manage the potential environmental impacts. Conducting a site assessment is a necessary step to evaluate the extent of the release and determine the appropriate response measures. This process helps to protect public health and the environment by identifying the source and impact of the release, ensuring that corrective actions can be implemented in a timely manner.

While performing new installations and conducting regular monitoring tests are important activities in the operation of underground storage tanks (USTs), they do not address the immediate need for action in response to a confirmed release. Waiting for external verification would delay necessary actions and may exacerbate the situation, leading to greater environmental harm and potential legal consequences. Prompt notification and assessment are therefore essential for compliance and effective response to a release of hazardous materials.
