Studies for the Environmental Impact Assessment

Name of project:
Screening Reports and Environmental Impact Studies in support of hydrocarbon exploration and production, onshore and offshore
Country: Area of study:
Italy Various localities onshore and offshore
Hydrocarbon exploration and production Companies
Project objectives:
Preparation of Environmental Impact Studies (EIS) and Screening Reports for exploration permit and exploitation concession applications, well sites, seismic survey plans and pipeline layouts, onshore and offshore
Composition of the working group:
Personnel involved:
1 or 2 geologists, 1 GIS expert
Number man/months:
variable, average 4 per project
Project steps:
The activity follows the procedures of the Italian national and regional legislation. The studies are carried out according to four steps:
1. Planning policies framework: relations between the project activity and the national, regional and local development policies; legislative framework;
2. Project operational framework: description of the operational methodologies and of the characteristics of the equipments employed. A special attention is given to the estimate of waste production and of pollutants release in the atmosphere, in the soil and in the water bodies, and to the description of the techniques for risk prevention;
3. Environmental framework: description of the environmental components that may be affected by the project operations, with special reference to the legislative constraints, use of the land, meteo-oceanography, physical, chemical and biological characteristics of soil and waters, geomorphology, lithology, surface and ground waters, vegetation, flora, fauna and ecosystems, landscape.
In case of offshore areas, the parameters considered include the fishing and touristic activities, the sea traffic, the meteo-oceanography, the physical, chemical and biological characteristics of the water column, the bathymetric, morphologic and lithologic characteristics of the sea bottom, with a special attention, in case of a sealine lay down, to the dynamic of the present sedimentation and to the characteristics of the sediments involved in the digging; the benthonic biocenoses, the fishing resources, the presence of marine mammals and reptiles.
At the end, an analysis of the critical elements of the environment is done, in comparison with the perturbation factors related to the activities. A non-technical synthesis is also included as well as the assistance in course of the evaluation procedure.
5. In case of an EIS, a fourth phase of impact assessment is carried out, through the creation of relational matrices among the project actions, the perturbation factors and the parameters characteristic of each environmental component suffering the impact. Then the control values are defined, the threshold values and the estimated values of impact for each project action, upon which, the appropriate measures of mitigation are analyzed.
In case of protected areas involved by the operations, the incidence evaluation is carried out.
Should be necessary, a baseline survey can be carried out for the direct acquisition of certain parameters.
For the evaluation of some parameters, such as the dispersion of pollutants in the atmosphere and/or in the water bodies, mathematical simulation model can be applied
