Drake Cement has applied to increase its permitted clinker production rate by 10% and to remove a short-term clinker production rate limit.
According to a documents from the Arizona Department of Environmental Quality (ADEQ), the company is seeking to raise its permitted clinker production level from 0.66 million tpy to 0.726 million tpy. The company has also requested to remove a rolling three-hour clinker production rate limit of 83.33 tph.
The production increase would be achieved without the need for any additional equipment. The plant’s limestone requirements would increase from 1.056 million tpy to 1.197 million tpy, requiring an increase in the allowable hours for quarry crushing operation.
The ADEQ is proposing to issue the required revised permit, the department said in a public notice posted to its website, although the revision would result in an increase in particular matter emissions.
A public hearing will be held on 19 January to discuss the draft permit, while written comments can also be submitted to this date. A final decision will be issued following the hearing.
