Abstract

The present work of curricular integration, is of technical profile whose objective was the execution of environmental management in the process of closing the Puninhuaico dump located in the Pungalá Parish, as part of the project "Maguazo-Alao" intended for the provision of potable water to the city of Riobamba, Chimborazo province. The environmental management identified all the technical measures recommended to mitigate and / or eliminate the negative impacts generated at the closing stage of the dump. The work was developed under the Leopold Methodology for the Evaluation of Environmental Impacts, with the application of Checklists and Matrix of Environmental Interactions; and the Leopold Matrix for the final evaluation of the project. The interpretation of results was carried out objectively, with a statistical and graphic analysis based on the methods set forth by Duek and Burguera. The closing process was carried out based on the Environmental Impact Assessment and the measures proposed in the Environmental Management Plan; The dump has a total area of 1,997 hectares, the closure consisted of the formation of two platforms in the upper and lower part of the debris and the formation of the slope. Finally, a methodology for recovering the vegetation cover with plantations (trees and shrubs) native to the area was developed. The recovered area is 70% with a total of 1000 plantations using the Tresbolillo System because of the type of terrain and incline of the slope, the proposed species were: Quishuar; as a living fence, wax laurel; as silvopastoral system and kikuyo; as fodder, the remaining 30% of the intervened area was used as arable land. The development of Safe Work Procedures is essential in these types of projects to protect the integrity of the people, goods and services involved.
