After the screening of risks, the environmental risk factors that were in the unacceptable range were eliminated. Risk priority number was calculated. Those statements environmental risks that range from red three-dimensional matrix of risk, have a high risk priority number 600 and are in the unacceptable area .Therefore, for reduce and control them, has been developed environmental risk management and environmental monitoring program for this plan.
