Six Local Emission Standards Issued in Motor Vehicles, Oil and Gas Recovery and Other Fields

09-18-2008

With the approval of the municipal government, Beijing Municipal Environmental Protection Bureau and Beijing Municipal Bureau of Quality and Technical Supervision jointly issued six local emission standards: Limits and Measurement Methods for Exhaust Smoke Opacity from in-use Diesel Vehicles under Lug-down Test Procedure (DB11/121-2010), Limits and Measurement Methods for Exhaust Pollutants from In-Use Gasoline Vehicles under Steady-State Loaded Mode (DB11/122-2010), Limits and Measure Methods for Exhaust Smoke under Lug-Down Test From In-Use Agricultural Vehicles (DB11/183-2010), Emission Controls and Limits for Oil-Gas From Fuel Depot (DB11/206-2010), Emission Controls and Measurement Standard for Oil-Gas from Tank Truck (DB11/207-2010), and Emission Controls and Limits for Oil-Gas from Gas Station (DB11/208-2010) on January 12, 2010. The newly issued three motor vehicle emission standards about gasoline vehicles, diesel vehicles, and low-speed trucks proposed the relevant emission limits of light-duty gasoline vehicles, heavy-duty diesel vehicles, and transformed diesel vehicles of meeting the National Stage IV Emission Standards, and three-wheeled vehicles and low speed trucks of meeting the standards of phase II; and adjusted the technique contents the power correction coefficient of in-use diesel vehicles, wheel edge power limit, and engine speed range in the original standard. The newly added National Stage IV Emission Standards increased 30% of the emission limit of in-use gasoline vehicles than that of the National Stage III Emission Standards; and increased 34% of the emission limit of in-use diesel vehicles than that of the National Stage III Emission Standards; the newly added phase II emission limits for in-use three-wheeled vehicles and low speed trucks were increased by 16% than that of the corresponding limits of phase I. The implementation of these three new emission standards for motor vehicles provided the management basis for ensuring the emission status of vehicles to maintain their factory or treated levels, which could urge the vehicles of not meeting the emission standards to conduct maintenance timely, and be conducive to control the pollution caused by emission of vehicles. Three emission standards on oil and gas recovery of fuel depots, oil tank trucks, and gasoline stations were newly issued, compared with the original standard, the emission limit of oil and gas processing equipments in fuel depot was increased by 25%; Oil Tank Truck Emission Standard was renamed as Emission Controls and Limits for Oil-gas from Oil Tank Trucks, and the test method and the emissions limits for the impermeability and recall valves of the oil-gas collecting system on oil tank trucks; in the gas station emission standards, the requirement of installing the online monitoring and oil-gas emission processing equipments was added; according to this standard, the oil-gas recovery efficiency could be increased by 5% -10%, and the online monitoring system can conduct the real-time monitor the working condition of the oil-gas recovery equipments. The three emission standards of in-use vehicles will come into effect on June 1, 2010, and the three standards on oil-gas recovery from fuel depots, oil tank trucks, and gasoline stations will come into effect on July 1, 2010.
