The pipeline was part of the Cadereyta Refinery Reconfiguration Project, which involved the construction of ten new power plants and the expansion of four existing power plants.[2] The 24-inch pipeline's southern section runs from Nuevo Teapa (Tabasco state) to Poza Rica (Veracruz state) to Ciudad Madero (Tamaulipas state); the northern section continues from Ciudad Madero to the Cadereyta refinery.[3][4]

Environmental Impacts

In 2014 the Madero-Cadereyta Pipeline was tapped by thieves leading to an oil spill along a 6 kilometer stretch of Rio San Juan.[1]

The Pemex refinery in Cadereyta (also known as the Héctor Lara Sosa Refinery) is considered one of northeastern Mexico's worst polluters, spewing toxic fumes that can travel as far as neighboring Coahuila state. The refinery is listed by Greenpeace as one of the world's worst emitters of SO₂ (sulfur dioxide).[5]
