On the update of the sanitary classification of objects of oil production, preparation and primary oil refining (from the experience of designing of sanitary protective areas)

Abstract

There are given results of generalization of designing materials for sanitary protective areas of objects of the oil production, preparation and primary oil refining. It is shown that as a result of manufacturing technology enhancement, renewal of the hardware park and implementation of air-security actions aiming at exhaust fumes reduction and the reasonable use of passing oil gas, considerable changes happened over the last decade as regarding the impact of objects on the atmospheric air and population health. The accumulated expertise of designing and concordance of the projects of sanitary protective areas for the oil production, preparation and primary oil refining objects confirms that for the majority of objects of approximate sizes of sanitary protective areas determined by the actual sanitary norms and regulations are excessive. Single and average daily maximum concentration limits as well as allowed levels of cancerogenic and non-cancerogenic risks for the health of the population are provided at the distances from the borders of construction sites which are considerably less than the ones determined by the sanitary classification. Calculation data is confirmed by results of the systematic instrumental research. There are given guidelines to introduce changes in the sanitary norms and regulations. For a number of objects it is suggested to keep the existing classification.
