Dam projects have serious influences on environmental parameters; therefore, environment risk assessment of dam is one of the most significant aspects of environmental risk management in these projects. The present study was conducted with the aim of presenting a new model for assessing the environmental risk of dams in construction stage. After identifying environmental risks and using the EFMEA method, the risk priority number for each of the environmental aspects was calculated and classified. Then, to assess and prioritize the identified environmental risks, the VIKOR method was used. The results showed that in The EFMEA method and by comparing calculated risk numbers, the risk of water pollution of Balarood River with the risk priority number of 125 is in the first priority. In the VIKOR method, the risks of water pollution in terms of agreement (high, average, low) with weights (1,300, 1,000 and 0,700) were identified as the most important risks. In the present article, using EFMEA and VIKOR methods in the environmental risk assessment of the dam, the most important risks were determined. The most important proposed corrective measure to reduce the environmental risks is the construction and completion of wastewater treatment for industrial units.

The ninth olefin plan of Arya Sasol Petrochemical Company (A.S.P.C.) is regarded the largest gas Olefin Unit located on Pars Special Economic Energy Zone (P.S.E.E.Z). Considering the importance of the petrochemical unit, its environmental assessment seems necessary to identify and reduce potential hazards. For this purpose, after determining the scope of the study area, identification and measurement of the environmental parameters, environmental risk assessment of the unit was carried out using Environment Failure Mode and Effect Analysis (EFMEA). Using the noted method, sources causing environmental risks were identified, rated and prioritized. Beside, the impacts of the environmental aspects derived from the unit activities as well as their consequences were also analyzed. Furthermore, the identified impacts were prioritized based on Risk Priority Number (RPN) and severity level of the consequences imposed on the affected environment. After performing statistical calculations, it was found that the environmental aspects owing the risk priority number higher than 15 have a high level of risk. Results obtained from Low Density Polyethylene Unit revealed that the highest risk belongs to the emergency vent system with risk priority number equal to 48. It is occurred due to imperfect performance of the reactor safety system leading to the emissions of ethylene gas, particles, and radioactive steam as well as air and noise pollutions. Results derived from secondary assessment of the environmental aspects, through difference in calculated RPN and activities risk levels showed that employing modern methods and risk assessment are have remarkably reduced the severity of risk and consequently detracted the damages and losses incurred on the environment.

Risk Assessment And Management

The existence, well-being, and sustainable development of the global economy hinges upon the state of the earth’s environment. Effective environmental risk assessment and management issues have become increasingly important. With the ever-growing global population and expanding economic development, we consume more natural resources, produce more waste, and develop more areas into the regions that are prone to environmental risks. Although humans have interacted with the environment for thousands of years, environmental risk assessment and management is only a recent research undertaking. As the industrialization has made the human-environment interactions more dynamic and complex, the increased environmental risks have propelled and compelled people to use technologies for identifying and solving problems. The earliest global environmental applications of remote sensing and GIS technologies began in the 1960s, particularly marked by the successful launch of the TIROS- 1, the first meteorological satellite, and the development of computer-based geographic information systems (GIS). The story Silent Spring (Carson, 1962) awoke the public’s environmental consciousness and promoted the public demands for governments to set up environmental protection policies and research priorities. The birth of the U.S. Environmental Protection Agency (EPA) in 1970 set the stage for modern environment risk assessment. The launch of the LANDSAT program in 1972 created a new way for monitoring global land use and land cover changes (Foley, 1999; Goward, Masek, Williams, Irons, & Thompson, 2001).

In recent years, various types of unexpected environmental accidents occurred frequently in China, which had caused great harm to economy and social development of China. The environmental risk assessment (ERA) model was built based on the related factors was described. Take the case of the proposed project of Cangzhou-Qiantongzhen freeway, the environmental risk was assessed by ERA model, and the corresponding countermeasures and emergency plans were put forward in the construction and operation period. The results show that the probability of water pollution in the sensitive sections along the freeway is 0.000927 to 0.011563times per year.

The petroleum industry holds long- and short-term environmental risks. Besides production fluids, all petroleum industry activities involve either use of fluids, which contain abundant substances, or waste generation, both associated with potential risk to the environment. The principal environmental risk associated with the petroleum industry is the risk of fluid spill/emission to the environment. Although in recent decades the risk analysis methodologies have matured, to date there is still no universally accepted methodology for environmental risk assessment in petroleum industry. In this chapter, the petroleum industry’s environmental incident history and statistics are presented. The environmental impact of the petroleum industry’s activities, its extent, and trends are analyzed. The overview of pollution sources with associated environmental risk is given along with the analysis of the causes and consequences of incidents in the petroleum industry.

The paper is devoted to the problem of protecting the environment from accidental environmental pollution from oil spills. Protection against this type of pollution is provided by a set of organizational measures and technical means that are aimed at preventing the occurrence of an accidental spill, stopping the flow of oil into the environment, eliminating the spill and eliminating its consequences. The development basis for a complex of protective measures in the form of a system including organizational measures and technical means was determined. This complex includes an operational procedure, the implementation of which provides effective protection against accidental pollution. The environmental risk assessment algorithm for emergency pollution of the environment during oil spills includes forming technical device groups for each technical object intended for moving oil. For each group, the environmental risk assessment is carried out by determining possible damage and the probability of an accidental spill, the causes of accidental spills are analyzed as well.

Case Basis

The article discusses the scope of the environmental risk assessment of genetically modified organisms (gmo). As environmental risks of the combination of gmo and herbicide application are not assessed on a case-by-case basis in the authorisation procedure of a plant protection product, the environmental risk assessment of gmo has to take account of the risks arising from herbicides against which the gm plants are engineered to be tolerant. As regards the scope of the environmental risk assessment of gmos, the Commission now moves in legislative ‘grey areas’. In 2017 the Commission has drafted a Directive to adapt the Annexes to Directive 2001/18/ec. Concerning the scope of the environmental risk assessment, the authors wish to highlight that the Commission is not empowered to answer questions of interpretation – be it even by a recital – as they do not fall within the scope of its regulatory powers (here: technical adaptations).
