Contaminated Sites and Long-Term Stewardship: Meeting Obligations for Residual Contamination

Mr. Gillay heads the Brownfields and Environmental Transactional Practice Groups and provides environmental counseling in connection with assessing environmentally challenged properties. Over the last decade, David has focused on the legal, regulatory, and technical impact and implications related to the vapor intrusion pathway. He also represents an influential multi-state environmental consultants’ association and works closely with leading technical experts on a wide array of environmental matters, including rapidly evolving vapor intrusion guidance. Prior to joining Barnes & Thornburg, he obtained an advanced environmental engineering degree and practiced as an environmental consultant on various projects across the country.

Mr. Hoylman has worked on more than 150 vapor intrusion projects over the past 9 years, focusing on VI mitigation and long-term risk management.  He currently serves on the EPA VI Science Advisory Committee, as well as chairs the standards management committee working to develop the national VI mitigation contractor credential and ANSI VI mitigation standards. He also serves on the board of the American Association of Radon Scientists and Technologists and is involved with ongoing research projects regarding the economic impact of radon-induced cancer and the effectiveness of national lending guidance on multifamily radon assessments.   

Dr. Schuver led the development of a technical document on ‘Radon Lessons’ based on the scientific observations from decades of Radon intrusion studies. He authored the national RCRA Corrective Action Environmental Indicator guidance for both Groundwater Migration and for Human Exposures. He also led the development of the 2001 Supplemental Guidance for Vapor Intrusion for RCRA EI Determinations which raised the awareness of VI exposures nationally and led to the development of the 2002 OSWER (RCRA & Superfund) draft VI guidance.
