## Abstract

The Environmental Protection Agency (EPA) is taking direct final action under the Clean Air Act to approve a revision to the Arizona State Implementation Plan (SIP). This revision concerns particulate matter emissions from dust generating operations that do not already have a permit within the Phoenix planning area. We are approving a state statute that requires the Arizona Department of Environmental Quality to develop and adopt a general permit that specifies episodic best management practices that are to be implemented by certain dust-generating activities.
