The project applicant shall ensure that the environmental impact assessment report is prepared by competent experts. In order to classify the investigation effort, the information in the EIS is to be divided into "priority" and "non-priority" in terms of the environmental impacts. Project documents which, according to the opinion of the project applicant, contain business or company secrets shall be especially identified. Data, which are not relevant for a specific project or are not available, need not be submitted.
With regard to an efficient process management, the earliest possible contact between the project applicant and the authorities is necessary for determining the scope of the investigation (scoping). The scoping can either be carried out as a formal procedure or as part of the investor service and should avoid unnecessary documentation and enable a concentration on the significant environmental effects.
