Transporte de emulsão asfáltica para imprimação: avaliação de impactos ambientais e proposta de plano de ação em casos de acidentes

Abstract

Assessing the possible environmental impacts in cases of accidents involving transportation of hazardous products is an important process for environmental protection and conservation. To carry out the activity of transporting dangerous products it is necessary to follow norms and legislations. In case of accidents, the transportation company must be aware of the environmental impacts that can be generated and implement measures to minimize them. The Action Plan, in areas of hazardous product transportation activity, is a document that simulates different scenarios in case of accidents and proposes immediate minimization measures. With this, the objective of the work was to define a study stretch (Passo Fundo/RS to Erechim/RS), characterize it, simulate two different scenarios involving accidents with hazardous products, evaluate the environmental impacts generated through the Leopold Interaction Matrix, and propose an Action Plan to minimize these impacts. Therefore, pertinent norms and legislations were presented, as well as the characterization of the dangerous product (Asphalt Emulsion for Priming), the correct identification of the vehicles that transport this product, the mandatory documents required during inspections, the minimum environmental emergency kit that must be stored in the vehicle, and a summary of the environmental licensing process at the state level. The scenario considered to have the greatest impact was the one that simulated the leak of the dangerous product in direct contact with water resources, generating water contamination, a source of extreme importance for the survival of living beings. An Action Plan was proposed to minimize the environmental impacts generated, as well as the identification of the main products/equipment needed to perform the services.
