SB641 modifies the definition of aboveground storage tanks and sets regulations for their secondary containment and inspection.

SB641 amends the definition of aboveground storage tanks to exclude devices with a capacity of 210 barrels or less containing brine water or other fluids produced in connection with hydrocarbon transmission and storage activities. It sets out tiered requirements for regulated tanks based on their proximity to public surface water supply sources or public surface water influenced groundwater supply sources. Level 1 tanks, located within a zone of critical concern, are regulated to a higher standard of tank and secondary containment integrity.
