He assists clients with many aspects of environmental and administrative law, including compliance counseling, permitting, due diligence, audits, commenting on agency rulemakings, administrative enforcement defense, and litigation.

Examples of Dan’s experience include:

  • Serving as working group leader on the Department of Justice-appointed Independent Corporate Compliance Monitor and Auditor team in conjunction with the Volkswagen AG emissions proceedings.
  • Negotiating favorable administrative settlements with EPA and state regulators for alleged violations of environmental statutes, including the Clean Air Act, the Federal Insecticide, Fungicide, and Rodenticide Act  and the Emergency Planning and Community Right-to-Know Act.
  • Counseling clients on “voluntary disclosures” under EPA’s self-disclosure policy and similar state-based policies.
  • Defending a leading crop-protection company in a multi-million dollar EPA administrative enforcement action.
  • Representing leading crop-protection companies in Federal Insecticide, Fungicide, and Rodenticide Act and Endangered Species Act federal litigation challenging product registrations.
  • Counseling companies on a wide range of permitting and compliance issues under the Clean Air Act and comparable state laws.
  • Preparing comments for companies and trade associations on both federal and state proposed air regulations.
  • Advising companies including a global pharmaceutical company and a major oil and gas company on the environmental aspects of corporate transactions and conducting related due diligence.

While at EPA, Dan formulated effective litigation strategies to defend agency actions and advised senior EPA officials on matters arising under a variety of statutes including the Clean Air Act, Clean Water Act, and the Resource Conservation Recovery Act. Dan was awarded an EPA commendation for outstanding counseling on administrative and regulatory law issues, and a Department of Justice commendation for assisting in the successful defense of EPA’s suite of greenhouse gas regulations.
