to avoid archaeological sites, existing villages orsettlements and to cross the minimum possible offorest areas. In general the route is in rathersparsely populated areas.oRationale for location of proposed activity(e.g.socio-economic, physical-geographic basis)Time-frame for proposed activity(e.g. start and duration ofconstruction andoperation)The approach is to assure the full sustainability ofthe infrastructure with particular care toenvironmental protection by avoiding to themaximum extent possible crossing or passingthrough sites presenting geological orgeotechnical difficulties, and by minimizing itstotal length.The Greek route does not cross anv NATURAprotected area/zone.Front End Engineering Design & EnvironmentalImpact Assessment Study has commenced in2011.It is expected that the Detailed Design andConstruction will be completed by the end of2014.Lifetime of operation - 40 years.Maps and other pictorial documents connectedwith the information on the proposed activityAdditional information/commentsHerewith attached is a map of proposed andalternative(s) route options in relation to theProject.iii) Information on exDected environmental impacts and proposed mitigation MeasuresoScope ofassessment(e.g. consideration ofi cumulative impacts,evaluation of alternatives, sustainabledevelopment issues, impact of peripheralactivities, etc.)The relevant National and European legislation rsapplicable, including the recently voted law401412011. The Preliminary Definition ofEnvironmental Requirements (an activity which isoptional in the new law) has taken place with thesubmission of the Preliminary EnvironmentalImpact Assessment Study (PEIAS).The Environmental Impact Assessment willfollow, considering, among others, the following:allowed land uses; location, design and technicalcharacteristics of the project, during itsconstruction and operation; evaluation ofalternative routes; data of the natural andanthopogenic environment; evaluation andassessment of potential significant impact to theenvironment during both construction andoperation; mitigation measures, in order to delete,reduce and counterbalance any potentialsignificant negative impacts; environmentalmanagement and monitoring; specialized studies,to be performed in the above mentionedEnvironmental Studies.
Expected environmental impacts of proposedactivity(e.g. types, locations, magnitudes)During construction-installation works, the levelof noise is expected to be temporary increased,due to the activities of construction machineryand workers. The operation ofconstructionmachinery is expected to lead to increase of theconcentration of COz in the atmosphere. It is alsoexpected that limited discharge at specifiedsuitable points of used lubricating oils will takeplace.During the construction of the IGB, constructioncorridors will have an expected width of 22m.In the above mentioned are4 the vegetation shallbe temporarily cleared. Following the pipelineinStallation, the reinstatement of the area will takeplace. In azone 5m wide from each side of thepipeline axis, no deep root plants will be allowed.The impact of the construction to the flora isconsidered as not significant, local andpelmanent.Due to the significant volume of ground worksnecessary for the gas pipeline bedding, themechanical effect on soils is the most significantone compared to all the other effects. The impacton soils could be assessedsignificant, local (atconsffuction site), short-term during construction,possible to reclaim and without cumulative effect.Inputs (e.g. raw material, power sources, etc.)During implementation of construction, smallquantities of concrete shall be incorporated. Thenecessary electric energy for welding and otherworks will be provided by mobile dieselgenerators. In general, water will not be used forthe pipeline construction and installation works.Water will be necessary for the performance ofthe hydraulic testing of the pipeline, followingwhich, the water will be discharged in the nearestwater basin.Outputs(e.g. amounts and types of: emissions intothe atmosphere, discharges into the water system,solid waste)During construction of the IGB, the followingtypes of emissions are expected:-dust- during construction works (mainly fromearth digging and reinstating works along thepipeline route and the at the stations)- "nonorganizedsource"-emissions from the engines of constructionmachinery, construction processes andtransportation of raw and other materials,equipment and staff.During construction, transmission pipelines arestress tested (hydrotested) according to standardsEN 1594, EN 12186, EN 12327. Duringhvdrotestins. water does not chanse its volume.
