STERLING, Ill. (KWQC) - Construction crews are working on resolving a report of a natural gas smell in the Sterling, Rock Falls area.

Crews are working at the old natural gas substation on McNeil Road, city leaders said in a Facebook post. The crews have a leaking tank of mercaptan on-site. Mercaptan is the odorant added to natural gas to detect leaks by smell. It has a strong scent, but is not hazardous on its own.

If you believe you have a gas leak at your home or business, city leaders ask that you please continue to call 911.

However, due to multiple odor-related calls in the area, response times may be slightly delayed, city leaders said.

“Thank you for your patience and understanding,” city leaders said.
