The district government of Fengrun in Tangshan, Hebei province undertook an emergency measure on Monday June 25 to counter heavy air pollution.
From 20:00 CST on Monday, all sintering machines and shaft furnaces at steel mills of the district were suspended. Production at independent lime kilns were suspended, while lime kilns at steel mills were required to halve output.
These measures come after the Tangshan government implemented similar measures during May 26-June 3, June 5-7, and June 20-21.
It is unclear when the restriction will be lifted.
