Aaron has focused on hazardous waste issues since the beginning of the federal regulatory program in 1980. With this historical experience, he offers clients broad-based regulatory counsel on hazardous waste matters, including compliance advice, strategic planning, advocacy, challenging rules in the courts, applying for permits and variances, and responding to enforcement actions. His clients include companies and trade associations in the chemicals, electronics, recycling, petroleum, pharmaceuticals, retail, steel, and mining industries, as well as government entities at the federal, state, and local levels, and non-profit organizations.

In addition to helping clients manage hazardous wastes and recyclable materials, Aaron advises companies on U.S. and international requirements for transporting hazardous materials and dangerous goods, as well as on worldwide regulations for preventing diversion of chemical products to use in the production of chemical weapons or illegal drugs. He also has considerable experience with the rules governing radioactive materials. 

He had the high honor of being appointed by the National Academy of Sciences as the sole attorney on a committee tasked with advising the U.S. Army on closure of the two facilities used to destroy the nation’s remaining stockpile of chemical weapons.
