EPA HINTS IT MAY RETAIN STRICT APPROACH IN NEWVAPOR CLEANUP GUIDE

摘要

EPA is suggesting its upcoming guidance for assessing whether toxic vapors stemming from hazardous waste sites require cleanup may retain strict default assumptions contained in a draft 2002 guide for assessing the risks posed by exposure to the vapors, according to draft site data the agency unveiled earlier this month. If the agency retains the strict assumptions when it finalizes the guidance, it will likely disappoint industry officials who are hoping the agency will instead adopt a more site-specific cleanup approach when assessing whether toxic contamination results in a new indoor air exposure pathway that requires cleanups.
