The Environmental Protection Agency (EPA) is proposing to revise provisions of the Arizona Regional Haze Federal Implementation Plan (FIP) applicable to the Phoenix Cement Company (PCC) Clarkdale Plant and the CalPortland Cement (CPC) Rillito Plant. In response to requests for reconsideration from the plants' owners, we propose to replace the control technology optimization requirements for nitrogen oxides (NO<INF>X</INF>) applicable to Kiln 4 at the Clarkdale Plant and Kiln 4 at the Rillito Plant with a series of revised recordkeeping and reporting requirements. We are seeking comment on this proposed action.
The agency’s own summary, as published.
