(GASCO) Environmental Impact Assessment Executive & Non Technical Summary This Environmental Impact Assessment (EIA) has Executive & been prepared to comply with the Egyptian Non Technical Environmental Regulations (Law No. 4, 1994 and Summary its Executive Regulations), in line with the European Communities/Directive 97/11/EC guidelines and GASCO's Health, Safety and Environment Policy (Appendix (5)). The scope of work includes construction of Tina-Abu Soltan pipeline. This pipeline will be constructed for the purpose of: • Feed Abu Sultan power station by natural gas. • Improve the national natural gas network. The route of pipeline starts from valve room northern Al Qantra – Fakous road (long. 32o 15’ 20” lat. 30o 49’ 50”) heads to the south parallel with Al Qantra – Abu Suwer road then heads to southeast crossing agricultural areas for 6km, then directed to southwest for 6km, then directed to the south crossing Bilbias – Sarabium road and finally tie in with valve room northern Abu Sultan – Cairo road (long. 32o 09’ 28” lat. 30o 23’ 50”). All positive and negative impacts were analyzed, and suitable mitigation measures were designed for the negative impacts. The undertaken project has major environmental and socio-economic positive impacts. From the environmental point of view, the use of natural gas (green fuel) will help in conserving the surrounding air quality due to the following reasons: − Natural gas produces neither particulates nor significant quantities of sulphur dioxide (SO2) and/or nitrogen oxides. − Only minute quantities of unburned residues of combustion, carbon monoxide (CO) or hydrocarbons remain after burning of the natural gas.
