Ice pads are cleaned and smoothed by ice resurfacing and edging equipment. Ice resurfacers maintain the entire ice surface, while ice edgers shave near the boards where the ice resurfacer cannot reach.

Ice resurfacing is typically conducted frequently, as often as every hour, while edgers are used less frequently but can still significantly contribute to emissions. Increasing ventilation during and after edger use, as well as on ice maintenance days, is recommended.

Ice arena operators must follow regular maintenance schedules as per the manufacturer's instructions for ice resurfacers and edgers.

Service of ice surfacers should include exhaust gas analysis and engine adjustments to reduce air pollutant emissions. The richness of the fuel or air-fuel ratio can be adjusted to decrease pollutant emissions. Routine maintenance of ice resurfacers includes tune-ups and replacement parts when needed (i.e. spark plugs, plug wires, timing belts, and fuel system components).

The goal is to maintain carbon monoxide and hydrocarbon levels at the lowest possible levels. Ice arena operators should produce a record of the last ice resurfacer emissions test at the time of inspection.

In addition to routine maintenance, ice resurfacers should be warmed up outdoors or in a room equipped with a carbon monoxide alarm and sufficient ventilation for at least five minutes prior to use, allowing the catalytic converter to reach the appropriate operating temperature.
