Environmental Compliance 101

Register here for the free August Mack webinar on "New Developments in Vapor Intrusion Evaluation in Indiana" on September 13th at 10:00 a.m.

Inhalation of contaminant vapors is often the primary exposure risk related to contaminated properties. Volatile substances such as gasoline and cleaning solvents emit toxic vapors as they evaporate. Exposure to toxic vapors becomes particularly concerning when the vapors emanating from contaminated soil and groundwater collect in overlying buildings. This phenomenon is referred to as vapor intrusion (VI) and is often the driver in risk based closures.

The Indiana Department of Environmental Management (IDEM) issued guidance outlining their suggested approach to evaluating vapor intrusion in Indiana. Their approach to vapor intrusion evaluation is contained in the Remediation Closure Guide (RCG) issued on March 22, 2012 and differs in some very important ways from the prior guidance that was issued in draft form in 2006.

This webinar will provide information on how to approach vapor intrusion evaluations based on the new guidance and how this approach differs from the prior guidance. This webinar will also provide important information as to how to approach vapor intrusion evaluations in a cost effective manner while minimizing disruption to site operations and will highlight situations where vapor intrusion evaluations can be completed without entering buildings.
