SLEW OF VAPOR INTRUSION GUIDES COULD LIMIT APPLICATION OF EPA POLICY

摘要

A slew of state, local government and other guidance documents creating policies for detecting and determining the risk of vapor intrusion could limit the application of a revised version of a controversial EPA guide expected later this year that is generally stricter than the state and other documents, sources say. Observers including state officials, environmentalists and real estate professionals say the strict EPA guide, which calls for extensive tests to determine vapor intrusion risks and stringent cleanup measures — particularly for groundwater contamination — has spurred other regulators and officials to develop guidances that take into account state and regional environmental diversity.
