## Abstract

We are approving two revised Commission Orders modifying the sulfur dioxide (SO<INF>2</INF>) allowable emissions at two stationary sources in Harris County, Texas. The Orders are separate, enforceable agreements between Simpson Pasadena Paper Company, Lyondel-Citgo Refining Company, and the Texas Natural Resource Conservation Commission (TNRCC). This action will incorporate these two Orders into the federally approved State Implementation Plan (SIP). The intention of this action is to regulate SO<INF>2</INF> emissions in accordance with the requirements of the Clean Air Act, as amended in 1990 (the Act).
