ENVIRONMENTAL IMPACT STUDY SAN JOSE – SAN RAMÓN CORRIDOR PROJECT. Public Disclosure Authorized BERNARDO SOTO HIGHWAY SEGMENT, FILE NO. 124-96. 1. EXECUTIVE SUMMARY______________. The project is for the extension and operation of the Bernado Soto highway. The project includes the construction of the works stated in the Announcement and Contract between the State and the Concessionary, and the operation and maintenance during the concession period. In return, the Concessionary will receive the consideration made by Public Disclosure Authorized means of toll tariffs The natural environment is located in areas that have been heavily built on, although in the indirect catchments area there are pasture lands and underseeds; la fauna is scarce and consists of that which is typical of semi-rural areas and that have got used to a human presence (rodents, birds, insects), and pets. The lands are flat to undulating with industrial sectors as well as commercial and residential ones. As regards the human environment, the density of occupation is low to medium. Public Disclosure Authorized The Concessionary company, AUTOPISTAS DEL VALLE S.A., assumes the environmental commitments that will be stated below (next table). Some obligations are preliminary to the initiation of the building works and refer to the stage of the studies and obtaining of permits.

THE PROJECT: This segment of the project belong to the second stage of the framework project: San José - San Ramón Corridor, and according to the provisions of the announcement, this must be initiated no later than two calendar years following the issuing of the order to start (which will be issued when the Concessionary has completed the conditions precedent that appear in the Announcement), and is to be completed in two calendar years. The extension will be initiated at the Juan Santamaría airport, and will end at the River Poás. Segment 2 of this stage is for the rehabilitation and improvement of the Río Poás – San Ramón segment. ENVIRONMENTAL IMPACT STUDY I-6 SAN JOSÉ-SAN RAMÓN CORRIDOR PROJECT BERNARDO SOTO HIGHWAY SEGMENT FILE 124-96. GEOAMBIENTE S.A. This highway travels through the province of Alajuela, along the cantons of Alajuela Central, Grecia, Naranjo, Palmares and San Ramón. This is the main access corridor to Guanacaste and Puntarenas, Puerto Caldera and Nicaragua, and starts at the end of the General Cañas Freeway (Airport) and the stretch ends at the intersection of access to the city of San Ramón, with a length of 40.6 Km. A typical section of the highway is currently made up of two lanes of 3.6 m in width with lateral hard shoulders of 1.8 m at both sides. There are ramp lanes of 3.35 m coinciding with the zones where the ground level is the ramp. The paving is concrete asphalt and its state of preservation appears to be good as it has recently been reinforced. The Concessionary will have to carry out all of the construction, rehabilitation and improvement works necessary in order to construct, re-build, extend and maintain each and every one of the segments, in accordance with the Invitation to Tender Announcement and the relevant contract, as well as the technical rules for engineering projects, technical specifications of construction, re- building and improvement, and maintenance and operational specifications, as well as the environmental requirements. According to the Road Project, the highway will have both vertical and horizontal signaling works, drainage, lighting and service areas, intersection and interchanges, extension of the road to 4 lanes, re-building and re-structuring of existing bridges, tolls and weights as well as Control Centers. The works to be carried out must be completed in accordance with the Invitation to Tender announcement and the Contract, with the Technical Rules of the Engineering Projects, the Technical Construction, Re-building and Maintenance Specifications, and the Operation and Maintenance Specifications, the CA-2001, along with the established environmental requirements. They cover the extension of the arterial road and the re-constructing of the roller surface, and other works such as the modification of intersection, interchanges and bridges. To do this, it will carry out: 9 Dismantling and cleaning in areas of extension of the highway. 9 Flattening works 9 Construction of drainage works (sewers, pontoons, recording wells, canals and similar units).
