In July 2018, EPA asked Amphenol Corporation to sample air quality conditions at its Franklin, Ind. facility (IND 044 587 848) related to VOC emissions from the groundwater recovery/air stripping remedial system.

1. Investigate whether ambient air at the Site is impacted by VOCs above risk-based screening levels,
2. Determine whether emissions from the groundwater remedial system venting pipe is a source of VOC contamination to ambient air, and
3. Determine the extent of VOC migration up to the property boundary in a downwind direction.

The sampling plan will help ensure that respondents react quickly and make appropriate changes to control VOC emissions, as needed.
