Draft Black Sea Regional Transmission Project ESIA Earthworks and rock excavation including dewatering if required, filling and grading and paving as needed. Steel structures. Foundations for substation control building and structures. Infrastructure works such as perimeter fencing, access and service roads and paths, water supply, storm drainage, cable ducts/trenches, doors and windows, and finishing work including masonry, plastering, filing, and painting. Design and execution will be based on applicable international regulations and standards in conjunction with Georgia norms and standards. The existing substations at Zestaphoni and Gardabani will be extended slightly to accommodate the new 500kV circuits at each location. This will require minimal additional land space since most of the new equipment will be installed within the existing substations. 2.1.2 Transmission Lines As mentioned previously, a transmission line has been planned on the same proposed route from Gardabani to Zestaphoni since the late 1980s. Activities including right-of-way acquisition, land clearing, construction of foundations and construction of towers were conducted between 1989 and 1991 along about 65 percent of this route. As noted above, many of these towers have been damaged or completely removed by scavengers and many foundations are in precarious condition. The segments of the transmission line include: Segment 1 - Gardabani to Akhaltsikhe. Right-of-way acquisition, land-clearing, and tower construction were completed along 114.8 kilometers of this 187.5-kilometer route (61 percent) in three main areas as shown on Figure 2-1: from kilometer 0 at Gardabani to kilometer 40.4 west of Marneuli (40.4 kilometers); from kilometer 53.9 east of Tetri-Tskaro to kilometer 99.5 near Tsalka (45.6 kilometers); and from kilometer 158.9 near Alastani to kilometer 187.5 (28.8 kilometers) at the proposed Akhaltsikhe substation. 1 Segment 2 – Akhaltsikhe to Zestaphoni. Right-of-way acquisition, land-clearing, and tower construction were completed along 48.0 of this 61.1-kilometer route (79 percent) in two main areas as shown on Figure 2-1: from kilometer 187.5 at the proposed Akhaltsikhe substation to kilometer 197.8 (10.3 kilometers) just inside the southern boundary of what is now Borjomi-Karagauli National Park; and from kilometer 210.9 just outside the northern boundary of the Borjomi-Karagauli National Park to kilometer 248.6 at the Zestaphoni substation (37.7 kilometers). Additionally, the right-of-way that connects these two segments through the National Park was initially cleared but has since largely re-grown. Remnants of some of the access roads are still present through these areas and are used as a local access route for recreational activities such as hiking and horseback riding. Segment 3 - Akhaltsikhe to Borchka (terminating near Vale on the Turkish Border). No activities have previously occurred on this segment, so this will be all new construction. 1 The distance in kilometers is measured from the origin at the Gardabani substation. 14
