What must be defined for HOT Generic Remedy cleanups to proceed?

For HOT Generic Remedy cleanups to proceed, it is essential to define the extent of contamination, which requires identifying contamination levels of at least 50 parts per million (ppm) minimum. This threshold is significant because it establishes a baseline for determining the severity and extent of the contamination present due to heating oil tank leaks. Working from this baseline allows for more effective planning and remediation strategies tailored to ensure that the cleanup is adequate to protect public health and the environment.

By setting this minimum level, it ensures that any recognized contamination problems are addressed early in the remediation process, which is crucial given that lower levels of contamination could still pose risks if not remediated appropriately. This approach directly aligns with environmental protection standards and cleanup efficiency, ensuring that all significant contamination is accounted for and managed accordingly.
