CVRD has received environmental clearance for construction of Pier IV at its Ponta da Madeira maritime facility, in Maranahão, which will allow it to increase the stockpile of iron ore that it sends there from its mines in Carajás. The Carajás Railway (CFC) will also have its own annual capacity raised to 50 million tonnes thanks to the doubling of 125km of track and the construction of a dedicated rail terminal adjacent to Pier IV. This new storage capacity for iron ore and iron pellets will be equivalent to half of all these types of products sold by the company last year.

The onshore components of the project will consist of two wagon dumpers, two stockyards for iron ore, a heavy duty forklift, two reclaimers and linking conveyor belt system. Offshore, Pier IV will be accessed via a 1.6 km bridge and will be equipped with a shiploader able to handle 16,000 tonnes per hour. Environmental protection equipment will be put in place, as well.
