AVALIAÇÃO DO PROCESSO DE ASSOREAMENTO NAS BACIAS E LAGOAS DO TERMINAL MARÍTIMO PONTA DA MADEIRA EM SÃO LUIS – MA E SUA CONTRIBUIÇÃO PARA O SISTEMA DE GESTÃO AMBIENTAL

Abstract

The concern of industries around the world with the environment is long-standing, and in recent years the acronym ESG - Environmental, Social and Governance, has gained more and more space in organizations. Faced with this new variable, the development and execution of preventive actions have increased and new controls are being required for better company management. The objective of this work was to evaluate the silting process that occurs in the basins and settling ponds of the Ponta da Madeira Maritime Terminal, through bathymetric surveys. For the study, bathymetric data provided by VALE S/A was used, seeking to understand the behavior of silting in different periods and the treatment carried out by the company to manage this problem. The bathymetric surveys were carried out using an autonomous boat and processed using Hypack software, license nº 04B8857917004341. The results showed that with control of the basins, via bathymetry and effective dredging, the levels of the basins were stable, with no occurrences of overflow or spillages for the community of Fumacê and for the São Marcos Estuarine Complex – CESM, in the case of spills to CESM, the water would meet all parameters within current environmental standards, CONAMA 430. We can conclude that the management of basins with bathymetry, dredging and environmental control regarding water quality is effectively guaranteeing compliance with the ESG rules required of organizations.
