ENVIRONMENTAL IMPACT STUDY FOR THE RUMICHACA PASTO DUAL CARRIAGEWAY, PEDREGAL CATAMBUCO SPAN, CONCESSION CONTRACT UNDER SCHEME APP NO. 15 OF 2015 -Pasto theThePedregal Rumichaca- Catambuco dualspan carriageway road project is a project of national interest and one of the most important in the department of Nariño, which is part of , subject matter of this Environmental Impact Study (EIS). Given its technical characteristics, which can lead to serious deterioration to the renewableimplementation, natural resources, or the environment, or introduce significant or notable changes to the landscape, -theANLA project- is subject of environmental licensing for its reason why it is submitted to considerationgathered of the National Authority of2015. Environmental Licenses , in compliance with provisions of decree 1076 of 2015, as well as the terms of reference for road projects, by resolution 0751 of The EIS SAS where the is developed by Gemini Environmental Consultants and contains the environmental characterizationn of the territory project of the second carriageway will be constructed, as well as the description of the actions and interrelation of the atural resourcesthere with said works.
On the other hand, the title holder of is the Concesionaria Vial Unión del Sur and is part of the eight second wave projects of the Fourth Generation of Road Concessions that are governed by the guidelines set forth in the CONPESation document 3760 of 2013 and byInfrastr the regulations (Law 1508 of 2012) related to Public Private Partnerships (PPPS) and who are in charge of the Ministry of Transport , through the National ucture AgencyEIA (ANI). area develop and Structuring the in accordance with characteristics has led to the ment Interiorof specific( activities such as the Archaeological Management Plan Prior Consultation activities, since according to the resolutions issued by the Ministry of the resolutions 22 and 23 of 2016) certifies the presence of ethnic communities.
