With consumption, underground storage needed to balance peak demand with approximately constant BOTAS, (Turkish Petroleum Pipeline Corporation) proposes construct an Underground Natural Gas Storage Facility approximately 200 south of Ankara in the central part of Turkey, approximately Golu (or "Salt Lake"): an extensive 162,000 ha marsh in the central region Turkey (Refer project location) The Tuz Golu Basin Underground Natural Gas Storage Project (UNGSP) will create storage caverns controlled fresh water dissolving the extensive underground natural salt formations existing depth

The EIA was officially approved by on 19.08.2003. salt domes located at approximately depth, have 1500 m, and will be leached using fresh water supplied the Hirfanli Dam (see below).

As consequence, BOTAS (although there exist no problem for such an amount water from groundwater resources revised the project design utilize Hirfanli Dam reservoir located from the project site fresh water source. (State Hydraulic Works), the authority responsible for resources allocation in Turkey, provided their official approval for use the required 10-1 2x1 m3/yr water from Hirfanli Dam. Hirfanli Dam, constructed one of the major multi-purpose dams which is used for energy and irrigation. annual inflow m3/yr. The water demand the project, the inlet flow the dam reservoir.

The lake continuously receives groundwater flows, which contribute brine through natural leaching these salt formations that exist in Tuz Basin.

The water supply modification scenario required BOTAS to supplement the EIA by preparing an "EIA Revision Report" according the Turkish Regulation, which MoEF in 2004. Differing the EIA Annex prepared to comply with requirements, only the project description and the new water supply scenario were included in this EIA Revision Report since Turkish EIA Regulation does not require for the water supply pipeline projects. BASELINE ASSESSMENT Present environmental resources within the project site were assessed investigations performed the EIA project team.

The highest background noise levels were measured dBA at Bucak Plateau during the measurement on February 18-19, 2002, and dBA (daytime) Municipality settlement area during the measurement on November 29, 2000. These noise levels are known occur due traffic, announcements and animals. The average daytime values recorded at the nearest locations the proposed project were 39.2 dBA Rasimusagi plateau and 52.5 dBA Omeraga plateau. These considered as typical values rural areas, which the noises originate from natural sources and manual activities, rather mechanical (e.g., industr

Tuz Golu Basin the water catchment area covering the lake itself, the rivers feeding lake and other the lakes related with it. Although exact borders not certain, the the basin around 530,000 hectare with a estimation. Since the basin is GOLU BASIN UNDERGROUND NATURAL STORAGE PROJECT EIA ADDENDUM EXECUTIVE SUMMARY it is better to discuss the fish species found within the close vicinity the project components. The small water bodies located within close vicinity of the project area do not represent a creek type characteristic. Tuz Golu almost totally dry in the summer and besides, the feeder creeks generally summer months. Thus, with no source fresh water during the summer, the resulting lake salinity from evaporation provides an extreme

There are main rivers namely Karasu, Pecenek lnsuyu feeding the lakes the basin, all which are fresh water. species mentioned in the EIA Report were not observed during field surveys carried out on April However based literature, these species are possibly found in lnsuyu River, the project site (Phoxinellus crassus found in and Aphanius chandrei found in 1944). The high salinity the lake and lake basin (including the discharge area) prevent these species from migrating these sites. a result, the proposed project (including surface facilities and brine discharge poorly inhabited poorly vegetated with any significant flora ENVIRONMENTAL IMPACTS EIA identified a number potential impacts associated with both construction operation phases the project.
