Tangshan, an industry hub of Hebei province in northern China, further intensified environmental control measures from June 6 to 9 to combat a round of heavy pollution.
Previously, Tangshan released the "Air Quality Guarantee Program for June", which required heavy-duty freight vehicles at or below National IV be banned at steel mills, coking plants, cement factories, utilities, ports and coal mines.
From 17:00 on June 6 to 12:00 on June 9, steel mills, coke plants, industrial kilns, etc. shall escalate measures to cut emissions, and VOCs-related plants and heavy-duty vehicles would be under strict control.
Steel mills classified as A and B are encouraged to voluntarily reduce emission. Other steel mills are required to increase the ratio of emission reduction and further reduce the emission of gaseous pollutants.
Coke plants are required to reduce pollutant emissions by prolonging coking time, optimizing operation and strengthening pollution treatment measures.
Brick and tile kilns and independent heating furnaces for steel rolling shall stop feeding new billets, and the cement grinding process and slag powder process shall cease operation.
Except for chemical factories and coking plants that are in continuous production, all other VOCs-related processes shall be shut down.
