On the analysis basis of Ukraine fuel and energy complex priority problems, the key role of the introduction of international standards ISO 14000, ISO 9000 series and HSE policy to create conditions for the prevention of technological effects on environmental components and the formation of prerequisites for a safe environment, both for personnel and for the population of the surrounding territories, are determined. Deterioration of natural resources quality and ecosystems degradation and possible levels of natural environments pollution are used as parameters for environmental risk assessing in the conditions of the fuel and energy complex operation. The concept of environmental risk management in this field is presented. The biomonitoring uses to assess the factors influence of the industry enterprises is proposed. Biomonitoring of the territory around the Burshtyn thermal power plant is carried out, taxonomic characteristics of phytoobjects are given, and the indicative prospects of plants, their diversity and classes of permanence are evaluated. A literature analysis is carried out regarding the convenience, ease of use and phytoindicative suitability of plants under the conditions of the man-made environment complex impact. The highest species representativeness in Asteraceae family, represented by 17 species, Fabaceae and Poaceae – by 5 plant species, is established within the study area. The highest phytoindicative potential of Cichorium intybus L. and Achillea millefolium L. under the influence of Burshtyn thermal power station is revealed, which indicates the possibility of effective use of these plants as sensitive monitors of the fuel and energy complex enterprises ecological state.
