SHANGHAI, Mar 14 (SMM) – The weather bureau of China's steel capital of Tangshan lifted the red alert on smog for two key areas, on 20:00 CST Wednesday March 13. This allowed local sintering machines that met ultra-low emission standards to restart.
Tangshan implemented the highest-level air pollution alert on March 1 when it escalated the alert from orange to red.
Steelmakers in the city continue to face restrictions in the Tangshan air pollution control plan for March, SMM learned. Sintering machines that failed to reach ultra-low emission standards will remain suspended.
