Monitoringemissions from a former Manufactured Gas Plant MGP site during remediationwas used to manage risks associated with inhalation of Volatile OrganicCompounds VOCs and contaminated particulates acting as an exposure conduitfor Polycyclic Aromatic Hydrocarbons PAHs and heavy metals. This riskmanagement case study presents a USEPA-approved air monitoring programimplemented to manage public health risks during remediation at a former MGPsite located in the southeast United States. Risk-based Acceptable Air ConcentrationsAACs were developed and a sampling regimen established to monitor potentialemissions to maintain contaminant concentrations below the AACs. The exposureduration used was based on a twelve-month project duration and an exposure timeof 24 hours per day; equations, toxicity values and sources were based onUSEPA’s Regional Screening Levels. A total 535 twenty-four hour time weightedsamples 269 VOC samples and 266 PAH samples were collected over the projectduration. Only minor levels of VOCs and PAHs were detected and no results wereabove the AACs. These timeweighted averages demonstrate that the real-time airmonitoring and control measures implemented at the site effectively maintainedconcentrations below the AACs and were protective of public health.
