On 19th December, the government of Henan province issued a Work Plan for Air Pollution Prevention and Control in Henan Province(consultation paper). The Work Plan requires 60 ceramic companies to achieve the ultra-low emissions before October 2018. If the companies get the plan done before June 2018, they can reduce the time for taking peak production and the volume of limited production during the period from 2018 to 2019. 

The plan claims that Henan province will push forward the ultra-low emissions in seven important industries, including steel, cement and ceramic industries.
