Article 111 (modified) requires permanent closure or removal of buried tanks out of service for over a year or exceeding 30 years of age, mitigating corrosion risks.
The decree specifies distances for tank placement: at least 3 meters from property lines and 1.5 meters from buildings for loaded vehicles. Overfill prevention systems, like automatic shutoffs, are mandatory to avoid spills. For aboveground tanks, bunding (secondary containment) must hold 110% of the tank’s capacity, protecting against environmental contamination.
Piping systems are regulated rigorously. Connections must be hermetic, using welding, threading, or flanges, with materials resistant to corrosion. Regular integrity testing, including hydrostatic or ultrasonic methods, is required. In environmentally sensitive areas, vapor recovery systems capture emissions during loading/unloading, aligning with air quality plans. These provisions not only prevent accidents but also ensure long-term infrastructure durability.
