Activities performed:Led in planning the work and organizing the environmental team on: (1) Environmental screening of the proposed project area in order to identify environmental and social concern associated with the implementation of the proposed activities; (2) Assessment of the magnitude and significance of the identified environmental and socials effects of the proposed activities; (3) Review of the existing environmental documentation in order to determine whether the identified concerns can be addressed through the provision of the existing documents. If this is case, to revise the existing documentation, by introducing references and/or amendments (EIA and EMP for km 15 and 45 and 45 to 121) in order to accommodate the proposed new road segment where appropriate; Otherwise, to prepare a specific EIA and EMP for the subjected road segment. (4) Assess any incremental environmental and social issues that can be caused by the increased scope of construction works, and conclude whether the existing EIA and EMP provides for adequate consideration of those issues. If this is the case, the Consultant shall amend the existing environmental documentation to reflect the changes scope of construction activities. (5) Assess the capacity of already identified borrow pits and conclude on whether those are sufficient for meeting the requirements of changes scope of construction in terms of availability of additional volumes of various types of construction materials, and if so, whether the borrow pits can be operated in an environmentally sustainable manner. If the need for additional borrow areas is defined, the Consultant shall suggest the alternative sites and assess those against their ecological and biological value, land ownership and land use patterns and feasibility of using those for the purposes of the project. The consideration of this aspect should also include identification and assessment of feasible material transportation routes, and the impacts and mitigation measures for using those routes shall be determined. Similarly, the identified waste management arrangements and facilities shall be assessed against the anticipated increased volumes of wastes to be generated. Should the existing arrangements and facilities be found insufficient for meeting the needs of the changes scope of construction works, the Consultant shall determine the additional mitigation measures to manage the wastes, including identification of other potential disposal sites and waste storage, collection and transportation arrangements. (6) Analyze the proposed changes against incremental environmental and social impacts which are associated with the introduction of those changes. The aspects to be considered for this analysis include generation of noise and dust, generation and disposal of various types of wastes, pollution of soils and water, deterioration of air quality, disturbances to flora and fauna, protected areas (mud volcanoes), change in land use, impacts on human health, traffic diversion, social, geological and archaeological aspects, etc. (7) Assess whether any additional amount of the construction materials shall be required by the proposed changes. If this is the case, the consultant shall assess the capacity of the borrow areas already analyzed by the existing environmental studies, and conclude whether these borrow pits are able to meet the requirements of the proposed alignment changes. If the capacity is found insufficient, the Consultant shall identify new sources and analyze the process of operation and reclamation of those newly proposed borrow areas. Such analysis should include an assessment of proposed sites in terms of their ecological and biological value, identification of the land use ad land ownership patterns, and conclude on the impacts the operation of those pits can cause. (8) The Consultant should also describe the procedure for obtaining necessary permits and licenses for the operation of new pits, define the process of the site reclamation, and provide the outline for the Borrow Pit Operation and Reclamation Plan to be prepared by contractor intending to operate the pit, before the start of the civil works. (9) Consider possible construction materials transportation routes and identify those more optimal in terms of minimal environmental and social risks associated with their use (such as generation of dust, noise and vibration, air pollution, soil compaction, etc.). If the existing routes are found to be suitable, the Consultant shall analyze the impact of transportation of additional volume of materials, i.e. greater load on the routes.
