EPA Weighing National Screening Levels For Petroleum Vapor Guide

摘要

EPA is developing guidance for site remedial managers to consider vapor intrusion from petroleum contamination stemming from leaking underground storage tank sites, weighing whether to develop national screening levels in the guide or to allow states to develop their own levels, according to a staffer in EPA's underground storage tank office.rnThe petroleum guidance, which will also provide direction on sampling approaches, will build on other existing vapor intrusion efforts, and is expected to follow the same development schedule as a separate guidance the agency is developing for vapor intrusion from other volatile organic compounds (VOCs) such as chlorinated solvents, according to Matthew Young, with EPA's Office of Underground Storage Tanks (OUST).
