His breadth of experience includes issues spanning environmental liability, toxic tort claims, products liability, establishing and maintaining federal and state regulatory compliance, and brownfield redevelopment issues, as well as handling sophisticated contract and commercial disputes. Trajan represents manufacturers, energy companies, industrial facilities, waste and recycling entities, and other highly regulated businesses. He is known to take his clients’ problems as his own, which is reflected in his acute knowledge of their businesses and adjacent sectors and industries, as well as a robust understanding of the regulations that govern their operations.

In both administrative hearings and in trial, Trajan represents clients against local and state agencies to successfully resolve municipal challenges and/or disputes. On the environmental side, he litigates federal cases arising under CERCLA and RCRA Superfund statutes, handling all aspects of the litigation process, including negotiations with responsible parties, contribution and allocation remedies, and cost recovery. He advises on matters concerning federal regulations, including the Petroleum Marketing Practices Act, the Clean Water Act, and the Clean Air Act, as well as various state-law equivalents. Additionally, he negotiates with state and federal environmental agencies, manages environmental response activities, and advises on obtaining environmental permits, CEQA permitting, and EIR challenges. He is familiar with all aspects of ADR and has recently begun to offer his services as a mediator. Trajan is also experienced with admiralty and maritime law, including arrests and attachments.

Trajan represents clients in class action litigation in state and federal courts. He handles matters involving toxic torts, wage and hour, and consumer protection. Trajan is highly adept at achieving early motions to dismiss and favorable class-wide settlements.
