'Minor' ammonia leak closes rink at Cottage Grove Ice Arena
An ammonia leak discovered Wednesday has temporarily closed a rink at the Cottage Grove Ice Arena.
An exposed ammonia pipe outside the arena had a minor leak affecting refrigeration of the western-most rink in the arena, City Administrator Ryan Schroeder said.
“What we’ve found is that the piping was supposed to be in a vault and it wasn’t,” Schroeder said. The pipe runs from a compressor room to the rink. “It’s not a safety hazard … but it does have an impact on our rink.”
