The Project implies a fairly limited direct footprint, localized to the sites where the dams and power houses will be built and the approximately 18 kilometers of river where the natural water flow will be affected. The plants will be located in a steep canyon at the mid-upper basin of the CVR, where the area to be flooded is limited. The Project will not cause the physical displacement of people and the land acquisition involves only private owners. Purchase negotiations are quite advanced and no land disputes or issues are foreseen. The Project’s site is a highly intervened agricultural area, with limited-to-nil mature primary forest, and mostly composed of pastures, agricultural crops, and patches of secondary riparian forest and low shrubs.
However, the Pando daily regulation reservoir involves the construction of a mid-size-to-large reservoir. Additionally, during environmental and social appraisal site visit, the Company was in the process of consolidating the hydro-biological baseline of the CVR at the direct impact zone. Therefore even if the CVR is very intervened by human activity and it is unlikely to have any unique ecological characteristics or sustain the habitat of any particularly interesting or valued species, at the time of appraisal there was limited data to support the significance and permanence of any potential impact of the project on natural habitats.
Furthermore, Pando and Monte Lirio are two of a series of approximately 14 run-of-river hydroelectric developments with water concessions in the CVR basin. The significance and magnitude of the potentially accumulated impacts is currently been assessed. Therefore, given a certain degree of uncertainty associated to the potentially direct ecological impacts, and the likelihood that the cumulative impacts may be irreversible and may involve a complex mesh of stakeholders, this Project was classified as a Category A.
The Environmental Impact Assessments (“EIA”s) did not identify any significant environmental or social impact or issue that would require major management efforts, but outlined, however, a series of tasks that must be completed to appropriate dimension the impacts and risks, and design effective mitigation measures and plans thereof. Besides the typical impacts and risks associated with a new construction and civil works (e.g. air and noise emission, wastewater and solid and hazardous waste generation, etc – PS3), the main environmental and social impacts identified during the EIA process are: (a) modification of the hydrological and sediment load dynamics of the CVR, (b) potential negative impacts on aquatic ecosystem, including the potential net loss of species with particular water quality and flow needs (e.g. spawning, migration, visual feeders, etc), or the invasion of exotic species as a result of change hydrologic dynamic (e.g. free flowing vs still waters in reservoir), (c) potential increase in erosion processes due both the daily fluctuation associated with the Pando reservoir (up to 5 meters) and to increased access, construction activities, and human intervention, (d) potential negative impacts on terrestrial ecosystems as a result of the modifications on the CVR basin at the project direct and indirect impact area. (e.g. access roads, ancillary facilities, tunnels, transmission lines), (e) potential impacts on socio-economic dynamics in an economically depressed area of the country (e.g. initial increase of employment, attraction of migrant workers, increase public service needs and costs, etc), (f) potential impacts on touristic activities, such as rafting on the CVR, (g) potential impacts and risk associated to the construction of the tunnels and the operation of Tunnel Boring Machines (“TBM”s) and other heavy equipment and machinery (PS2), (h) socio-economic impacts associated with land acquisition and land-use changes thereof (PS5), (i) potential loss of archeological sites/ artifacts (PS8), (j) potential indirect impacts to indigenous peoples migrant crop workers, that have been reported to occasionally and in small numbers seek employment in the project influence area (see PS7 above), and (k) dam safety and emergency and community preparedness downstream (PS4).
The Company, in coordination with the Lenders, has developed a comprehensive plans of action to comply with all the environmental management tasks established in the EIAs and to meet IFC EHS Performance Standards as well as other Lenders requirements (See ESRS for further details)
