The correct answer is: Installation of striker plates

The upgrade that was mandated for petroleum USTs by December 22, 1998, involves retrofitting with vapor recovery systems. This legislative requirement was implemented to address environmental concerns about the vapor emissions associated with underground storage tanks (USTs) containing petroleum products. Vapor recovery systems are designed to capture and recover vapors that would otherwise escape to the atmosphere during the filling of the tank or when a vehicle is being fueled. By enhancing the containment and reducing emissions, these systems play a crucial role in protecting air quality and reducing the risk of ozone formation. The mandated retrofitting underscores the recognition of the potential hazards posed by vapors, which can contribute to air pollution and health risks. Retrofitting USTs with vapor recovery systems represents a significant step in regulating and improving the performance of fuel storage systems, ensuring both safety and environmental compliance. Understanding this requirement is essential for compliance with regulatory standards and for promoting public health and environmental stewardship in communities served by petroleum USTs.
