Overview of Services

Air quality laws and regulations pose some of the most complex legal challenges that businesses face. Air laws cover stationary sources like refineries, cogeneration plants, and hospitals, as well as mobile sources such as trains, trucks, and automobiles. Regulatory violations can result in significant penalties, require expensive and disruptive retrofit requirements and, in extreme cases, shut down facilities altogether.

Our lawyers include former regulators and experienced environmental attorneys who have a wealth of knowledge about how air quality  regulations apply and how enforcement works. This experience allows us to develop targeted and effective compliance solutions. We also have long-standing relationships with seasoned technical experts who support our legal team in evaluating compliance concerns. In addition, we help our clients advance their business interests by monitoring and attempting to improve air quality legislation, regulations, and guidance that impact their operations.

When litigation is necessary, we defend clients in enforcement actions brought by local air districts, the California Air Resources Board (CARB), and the U.S. EPA. We vigorously litigate complex cases, but we also focus on resolving matters through practical and cost-effective settlements.
