Abstract :

The purpose of this study is using reformed muhlbauer method in order to evaluate the pipeline environmentalrisk levels. In this method, the total index represents the hazard probability and the leakage factor represents theimpact intensity. The final risk score is obtained by dividing the total score into leakage factor. 32 % of thepipelines contain very high risk and 11 % of the pipelines contain high risk. Medium risk belongs to 23 % of thepipelines and 34 % of the pipelines contain low risk. According to the results of kent malhauber method, themost important risk factor in this study is the High activity levels, low depth of coverage, lack of adequateeducation about the risks of pipelines to nearby residents, the lack of emergency messaging system, Intersectionwith multiple faults, Urban tissue, Population density and Valuable areas Like the National Natural.
