LaFarge isn’t sure why Utica residents are feeling vibrations after quarry blasting — the blasts are well below regulation — but company officials said Thursday they’ll look into why and try to fix it.

Robert Sapp, operations manager for LaFarge, and plant manager Cody Tucker offered to install seismographs in places of concern and to explore ways to cut down on disruptions reported in the village.

“We’re going to take this very seriously,” Sapp said, pledging to open a line of communications. “We can also have somebody come here, an expert, and tell you a little bit more about that.”

LaFarge had a blast last week that set the phones ringing at the Utica Village Hall. Trustees were quick to assure their concerned constituents they felt it too.

“My entire house shakes,” said Trustee John Schweickert. “There absolutely are vibrations. There are things falling off walls. We have a lot of citizens come forward.”

“The one two or three weeks ago knocked pictures off my wall,” said Trustee Jim Schrader. “I can literally feel it in my shop, which is basically a mile away from you guys.”

As a goodwill gesture, LaFarge presented the village with a $1,500 donation for the fireworks and earlier donated $500 to the Little League.
