Luminant Responds to U.S. Supreme Court Cross-State Air Pollution Rule Decision

DALLAS – While Luminant is disappointed with today's remand of the Cross-State Air Pollution Rule, we are pleased with the Supreme Court's confirmation that the EPA has a "statutory duty” to avoid over-regulating.

We will now closely analyze the opinion and evaluate what additional legal or regulatory actions are necessary to determine any final requirements of an interstate transport rule. In addition to further proceedings before the appellate court as a result of the Supreme Court's remand of the case, several other appeals are pending regarding aspects of the CSAPR and other related rulemakings, and it is uncertain when and how the rule's precise requirements will be completely resolved and implemented.

Luminant remains proud of and committed to upholding its legacy of meeting or outperforming all environmental laws, rules and regulations. The company will assess and determine its ultimate business and operational decisions based on the requirements of the final interstate transport rule when those requirements are fully known.
