The ruling explicitly rejects the notion that favorable technical certification can indefinitely extend the operational life of tanks beyond three decades. The court found that allowing older equipment to operate without time limits while imposing them on new installations would create an illogical contradiction in the regulatory framework. Before the September 10 attacks that damaged Saudi Arabia’s East-West pipeline and tightened global fuel markets, the Chilean underground storage system was already carrying approximately 4 to 5 million barrels per day through infrastructure subject to these new age restrictions.
Argentina maintains a fundamentally different approach that does not impose an automatic retirement age. Resolution 404/1994 establishes escalating inspection frequencies based on tank age: hermetic testing every five years for tanks up to five years old, every three years between five and ten years, and every two years for tanks exceeding ten years. Certain high-risk locations require testing every 180 days under Decree 2407/1983 when underground services, tunnels or structures exist near or above dispensing points. Continued operation depends entirely on passing these technical evaluations rather than reaching a predetermined age threshold.
The Chilean precedent introduces a fixed lifecycle constraint that could accelerate infrastructure replacement cycles across the country’s retail fuel network. While both regulatory models pursue safety objectives, Chile’s temporal barrier creates capital expenditure certainty for station operators but eliminates operational flexibility, whereas Argentina’s performance-based system allows indefinite operation contingent on demonstrated integrity. The divergence reflects broader regional debates over prescriptive versus outcome-based regulation in aging energy distribution infrastructure.
