Environmental and Social
 Impact Assessment

This Peruvian South Pipeline Consortium (Enagas-Odebrecht) project includes the construction, operation, and maintenance of a 1,086-km natural gas pipeline. E & E subsidiary Walsh Peru developed the Environmental and Social Impact Assessment for the project to construct a new 100-km line in the Cusco region and conducted environmental baseline studies of the Puno (300+ km), Arequipa (10 km), Moquegua (100+ km) and Tacna (200 km) pipeline segments.

Sensitive Resources

From Cusco through the regions of Arequipa and Moquegua, the pipeline route traverses mountains, jungle, and an agricultural valley before reaching the coast at Tacna. In addition to navigating onerous terrain, challenges included handling diverse areas of biological sensitivity in a variety of ecosystems. The route also passed through areas inhabited by indigenous communities.







Involve the Community

Walsh Peru combined a team of 35 environmental specialists with more than 50 local professionals to address ecosystem and biodiversity issues, and conducted more than 50 workshops and public hearings to invite citizen participation and to include indigenous communities in the process. Ultimately, we garnered the participation of more than 500 community members.







Energy Security and
Economic Opportunity

Recognizing the broad community support of the project, authorities approved the environmental impact study. Traditionally an agricultural region deriving income from tobacco and cacao beans, the increased fuel and energy security brought to the South Andean region through this project can spur additional economic opportunities.
