Environmental impact assessment

Environmental Impact Assessment (EIA) is one of the basic and important reports prepared by environmental engineering consulting companies at the request of employers from various industries including oil and petrochemical industries, metal industries such as steel, chemical industries and other industries. . This report examines the effects of the construction and operation of various projects on the natural, physical, etc. environments in the environmental, cultural, and economic fields.

Environmental impact reporting process

1. Ensuring the need or lack of need to carry out environmental impact assessment according to the grouping of industries required to prepare an opinion report on the documents of the Environmental Protection Organization
2. Determining the scope of environmental impact assessment in order to determine the boundary of the study
3. Examining the existing situation and determining the existing conditions before the project components
4. Prediction of effects
5. Evaluating the effects and prioritizing and determining the important items
6. Set up an environmental management plan
7. Preparing reports and making decisions
8. Decision making

Procedures for environmental impact reporting

In the first stage, according to the classification provided by the environmental organization, the industries are required to submit an environmental impact assessment report, the decision to prepare this report for the target industries is determined.

In the second stage, to carry out the assessment of environmental effects, according to the information provided by the employer’s industry, the boundaries of the project and the range of environmental effects are investigated. Determining the scope of influence also includes specifying physical boundaries.

In the third stage, the environmental, social, cultural and economic conditions of the region are examined before the construction of the project.

In the fourth stage of environmental impact assessment, the construction and operation stages of the project are predicted. The characteristics of the effects include the nature of the effect (positive/negative), the magnitude of the effect and the intensity of the effect, the time period of the effect (short-term, medium-term and long-term), the importance of the effect, the probability or certainty of the effect.

In the next step, these effects can be evaluated using different methods. Methods such as the checklist method (evaluation without any kind of size of their approximate volume), the matrix method (quantitative evaluation of the effects and taking into account the activities column and the effects column), network analysis (the evaluation of the second and third order effects is used) , superimposition of maps (production of different layers of information in the form of maps and their overlap), pollutant release modeling (use of environmental models in determining pollutant distribution and identification of vulnerable areas; attention to the type of pollutant under investigation can be obtained from various software such as AERMOD , AERFLOW and… used to model pollutants.).

After the results of this stage are determined, the environmental management plan for the construction or construction and operation phase is adjusted according to the target industry. Finally, according to the results of the previous stages and the points obtained for the various operations in the industry in the construction and operation phase, the appropriate decision is made and reflected in the report.
