The Clean Air Act (the CAA) is a core federal environmental law that has imposed increasingly stringent requirements on air emissions from stationary sources. Over the past four decades, Sidley’s lawyers have advised clients on some of the most complex regulations, permitting, and enforcement issues under the CAA.
Our clients extend across all major industry sectors, including numerous national trade associations and electric utilities, oil and gas, wood products, pulp and paper, and chemical and other manufacturing. We provide counsel and write comments on EPA rulemakings, represent clients in judicial proceedings reviewing EPA rules, assist clients in obtaining permits and developing and implementing compliance programs, and guide clients through voluntary disclosures to the EPA to achieve a resolution before enforcement. When necessary, we also defend clients in enforcement proceedings before the Federal and State Courts.
We have extensive experience with matters involving the CAA’s New Source Review (NSR) program. Our team has litigated and defended permit challenges through the courts of appeals—and defended claims brought against clients in multiple industrial sectors. For instance, when a utility faced multi-billion dollar NSR claims, it turned to Sidley.
