Clarifies procedures for maintenance of underground storage tanks.

This bill requires owners and operators of underground storage tanks (like those at gas stations) to follow specific safety and maintenance procedures. It mandates regular testing based on tank age, stored materials, and nearby water sources; requires adherence to EPA safety standards (with stricter rules near protected water areas); and demands 24-hour leak reporting to authorities. Owners must designate a responsible person for compliance and corrective actions, and face triple damages if leaks aren’t fixed within 14 days. The law directly affects businesses using underground tanks and strengthens environmental protection through clearer enforcement.
