Determination of the Environmental System for the environmental impact study of a gas pipeline in operation located between the states of Tlaxcala and Puebla

Abstract

Abstract: This article describes the methodology applied by the authors to delimit the Environmental System for an environmental impact assessment study for a gas pipeline currently in operation located between the states of Tlaxcala and Puebla. The delimitation of the Environmental System and the criteria for it are a key point in the characterization and initial environmental diagnosis of the ecosystems where works, activities or projects are planned to be developed, as a reference framework for the identification of environmental impacts, so it is an indispensable requirement in the Environmental Impact Statements. For this case study, the methodology includes criteria for identifying ecological planning programs, delimitation of hydrological basins and sub-basins, land use and vegetation and geomorpho-edaphological features and urban infrastructure in the project area and its area of ​​influence, as well as the same operational characteristics of the oil infrastructure, which represents an appropriate case of analysis where the legal requirements established in the legal regulations of environmental authorities in the matter are met and a correct description of the study area is ensured.
