The environmental impact assessment of the relocation project of Tanquipor’s liquids terminal pier was developed to support the decision on the environmental feasibility of relocating the activity of unloading chemical products by sea. This came as a result of the approval of a third crossing route over the river Tejo through the Chelas-Barreiro corridor.
Considering the fact that the more relevant direct negative impacts would be the ones related to changes in hydrodynamics and local sedimentary scheme, we resorted to using the hydrodynamic and transport model established for Tejo’s estuary, reformulating its grid locally in order to portray the specific conditions of the study’s area and its factors.
The study led to the conclusion that the project offers a significant improvement in security, evidencing that the new pier will be better for environmental resources more sensitive to pollution due to product spillage. However, it recommends mitigating measures for external risks, such as the proposal of the urban plan of Quimiparque’s land and its surrounding area, as well as for the project for the third crossing route over the river Tejo.
