Community group flags stack-test finding that emissions may show more PFAS than inputs

Petersburgh Community Action (CA) members spent part of their meeting reviewing recent staff test reports and questions raised by an independent chemist who examined data obtained via a FOIL request. The group said the chemist, Denise Driver Pointer, forwarded technical questions about laboratory conversions and the list of analytes included under the facility's permit.

Members discussed a specialist’s explanation from a community call that heating processes can transform chemicals during combustion. "They found that there was more PFAS coming out than what was going in, and he explained it really well," Speaker 2 said, relaying the expert’s account and prompting questions about whether routine permit testing looks for transformation products as well as parent compounds. Participants agreed to send a focused set of follow-up questions to the Department of Environmental Conservation (DEC) and the facility’s data contact and to request continuous-emissions monitoring records cited in the permit.

The committee identified the 2014 permit contaminant list (item 56) as a central document to review; members noted it names only a handful of parameters such as hydrogen fluoride, PM-10 and DOCs and does not clearly list a broad PFAS panel. Speaker 1 said the committee will seek clarification from DEC on which analytes are required and whether lab methods would detect PFAS that form during heating processes. The group also planned to share the chemist’s comments with DEC and with DDC to request technical explanations and conversion details.
