Drake Cement to raise production limit

According to documents from the Arizona Department of Environmental Quality (ADEQ), Drake Cement 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 operations.

The ADEQ is proposing to issue the required revised permit, the department said in a public notice posted on its website, although the revision would result in an increase in particular matter emissions.
