US: Drake Cement has applied to the Arizona Department of Environmental Quality (ADEQ) to revise its air quality permit in order increase its clinker production at its Paulden plant by 10% to 0.73Mt/yr from 0.66Mt/yr at present. The cement producer is required to make the application as the increased production could increase its emission of particulate matter. The plant is also requesting a removal of the rolling three-hour clinker production rate limit of 83.3t/hr and an increase in the allowable hours of quarry crushing operation. The ADEQ will be holding a public hearing on the revision on 19 January 2017.
