HF Monitor at PES Refinery

The city’s health department downplayed the incident Wednesday, saying its Air Management Services (AMS) inspectors suspected the gas meter was not properly calibrated, and requested that the refinery and the U.S. Environmental Protection Agency double-check the tests.

“Both confirmed that there was no HF present in the air,” James Garrow, the health department spokesperson, said in an email. “The AMS inspectors took the improperly calibrated meter out of service.”

Garrow conceded, however, that one of the city’s meters, which was being used to confirm PES’s own zero readings, had not been functioning properly.

“[Air Monitoring Service] inspectors tested for the presence of HF to confirm the zero readings reported by PES,” Garrow said. “Due to the meter not being properly calibrated, the inspectors requested that the EPA and PES confirm the zero readings. Both confirmed that there was no HF present in the air. The AMS inspectors took the improperly calibrated meter out of service.”
