According to the Chapter 3 of the Regulation on the Assessment of Environmental Impact approved by Order of the State Ecology Committee of the Russian Federation of May 16, 2000 No.372 insofar as it does not conflict with the current legislation of the Russian Federation the EIA investigations include:

• Characteristic of proposed economic activity and possible alternatives;
• Research of the territory state that can be influenced by proposed economic activity;
• Detection of possible environmental impacts;
• The likelihoods of  risks appearance;
• The extent, scale and area of distribution, the forecast of the ecological and socio-economic consequences;
• Measure mitigations and their effectiveness and possible realization;
• Working out of the environmental quality monitoring plan on each stage of the project realization.

For projects connected with construction, reconstruction as well as location of the objects of transport infrastructure the EIA is conducted on the base of the engineering-ecological investigations. The specific requirements to the engineering-ecological surveys are described in the Formulary No.47.13330.2012 “Engineering investigations for construction” issued by the Ministry of regional development of the Russian Federation in 2012.

Types of work and investigations that form a part of engineering-ecological investigations:

The collection, processing and analysis of published stock materials, data on the state of the environment and a preliminary environmental assessment of the territory;

• Ecological decoding of aero- and space images;
• Route observations;
• Ecological-hydrogeological investigations;
• Ecological-hydrological investigations;
• Ecological-criopedological investigations;
• Soil investigations;
• Geoecological probes and assessment of air, soil, surface and ground waters pollution;
• Laboratory chemical-analytical investigations;
• Investigation and assessment of radiation situation;
• Gas-geochemical investigations;
• Investigation and assessment of physical impacts;
• Biological investigations;
• Social-economic investigations;
• Sanitary-epidemiological investigations;
• Archeological investigations;
• Making report.
