The U.S. Environmental Protection Agency (EPA) has proposed withdrawal of a requirement that certain power plants (typically coal-fired) in Texas participate in the second phase of the Cross-State Air Pollution Rule (CSAPR) trading programs for annual emissions of sulfur dioxide (SO2) and nitrogen oxides, according to a notice in the Federal Register. The move “…is intended to address a decision of the U.S. Court of Appeals for the District of Columbia Circuit remanding the CSAPR Phase 2 SO2 budget for Texas to the EPA for reconsideration,” the notice said.
