McALLEN, Texas (ValleyCentral) — McAllen City Hall was evacuated Thursday afternoon after what was called “sewer smell,” authorities said.

ValleyCentral spoke with McAllen Fire Chief Juan Gloria who said they received a notification of an unknown smell in an area of the first floor of the city hall.

He said that the area was evacuated as part of a safety protocol and firefighters entered the building with gas monitors to look for inhalation hazards.

“It happened to be sewer smell coming from a utility closet,” Gloria said.

He said that paramedics made contact with several employees for evaluations, but there was no need to transport anyone to the hospital.

Normal operations will resume at the city hall tomorrow, he said.
