On September 15, Gina McCarthy, assistant administrator for air and radiation at the Environmental Protection Agency official told the House Science, Space, and Technology Committee under the new Cross-State Air Pollution Rule, requiring power plants to reduce interstate transport of sulfur dioxide and nitrogen oxides, that the agency has the flexibility to increase state emission budgets. EPA also is evaluating the relationship between the rule and electricity reliability. The Cross-State Air Pollution Rule covers 27 states, but officials and industry leaders in Texas have claimed the final rule is much harsher than the proposed rule.
