DOE Deal to Monitor Euro-4 Diesel Quality

As part of a drive to protect the environment and curb air pollution, the Comprehensive Monitoring Office at the Department of Environment has reached a deal with the National Iranian Oil Refining and Distribution Company to regularly monitor the quality of Euro-4 diesel, director of the department said.
"Monitoring the amount of sulfur in Euro-4 diesel is of great importance, that's why DOE will check the index in 25% of gas stations every other week," Shina Ansari was also quoted as saying by ISNA.
According to the official, as per the agreement signed between DOE and NIORDC, the quality of diesel distributed nationwide since May 22 will be controlled all year round through random sampling.
