On September 21, the ministry of ecological environment officially released the action plan for comprehensive control of air pollution in the beijing-tianjin-hebei region and surrounding areas in the autumn and winter of 2018-2019.The plan calls for the beijing-tianjin-hebei region and its surrounding areas (" 2+26 "cities) to fully achieve the air quality improvement target for 2018.On March 31, 2019, the average concentration of fine particulate matter (PM2.5) in the above areas decreased by about 3% year-on-year, and the number of days with heavy or above pollution decreased by about 3% year-on-year.

In order to accomplish the above goals, the plan has formulated specific main tasks and safeguards.One of the main tasks is to carry out special action on pollution control of industrial kilns, to carry out online screening of industrial kilns in casting and other industries. As of November 1, 2018, industrial kilns not included in the management list are not included.It is required to formulate the implementation plan of comprehensive remediation of industrial kilns, put forward rectification requirements by classification, and promote structural upgrading of industrial kilns and pollution reduction.

In a closely watched the fall and winter peak production side, "the plan" is different from last year, for the iron and steel, building materials, coking, casting, nonferrous metal, chemical industry such as emissions, cancelled the uniform limit production scale, to adjust measures to local conditions to promote industrial enterprise peak production, the implementation of differential peak production, according to the heating period around the monthly environmental air quality forecast results, can shorten or extend the peak production time appropriately.In the specific peak fault plan, the plan can not limit the production of environmental benchmark enterprises whose industrial pollution emission performance is obviously better than that of other enterprises in the same industry

For foundry enterprises: the plan stipulates that the discharge concentration of particulate matter and sulfur dioxide of the foundry smelting equipment is stable to 20 mg/m3 or 100 mg/m3 (the cupola must be installed with automatic monitoring facilities for flue gas emission), the production may not be restricted.

For the casting pig iron production enterprises: the plan stipulates the pollution emission control of sintering and blast furnace processes of these enterprises, which shall be implemented according to the relevant standards of the iron and steel industry;If the organized discharge, unorganized discharge and transportation of bulk materials and products meet the ultra-low emission requirements, the production may not be restricted.

In order to ensure the healthy and stable development of foundry industry, environmental protection management level, industry support emissions level significantly better than the same industry the development of foundry enterprises, China foundry association actively with the national ministry of industry and environmental protection departments many times communication, suggest to different levels of environmental protection foundry enterprises implement the cost management, and the casting and foundry pig iron production enterprises put forward concrete Suggestions for peak production, the relevant departments attach great importance to, for the "solution" in the casting industry the peak production plan formulation of support.
