September 2016

On August 24, Ohio EPA released new guidance that incorporates an unprecedented approach to vapor intrusion.

In the case of one particular contaminant – trichloroethylene (TCE) – the Agency expects action within days if the associated trigger levels are exceeded. The guidance has major implications for businesses, property owners, consultants and attorneys. Read the Client Alert here.
