(a) Measuring air quality. Owners of indoor ice arenas must measure carbon monoxide and nitrogen dioxide air concentrations in each arena when internal combustion engine-powered ice maintenance equipment is used.
(b) Persons who can take measurements. Measurements must be made by an individual who has received annual training on monitoring equipment in use.
(c) Frequency of measurements. Owners must measure air concentrations at least twice per week after using an internal combustion engine-powered ice resurfacer. Measurements must be taken:
(1) At board height, inside the boards, and at the centerline of the ice;
(2) Twenty minutes after completing resurfacing unless the AHJ has granted the owner approval to measure under an alternative schedule;
(3) At time of maximum use of the resurfacing machine; and
(4) At least once on Saturday or Sunday of each week that the arena is open to the public.
(d) Owners must measure air concentrations at least once per week after using an internal combustion engine-powered ice edger. Measurements must be taken following a time of maximum ice edger use at board height, inside the boards, and at the centerline of the ice:
(1) Twenty minutes after completing edging if the arena building is open to the public when edging occurs; or
(2) Before the public reoccupies the arena, if the arena is not open to the public when edging occurs.
(e) Owners may measure under an alternative schedule if the AHJ has approved one.
(f) Measurement records. Owners shall keep a record of measurement findings and make them available to the AHJ upon request.
(g) Additional measurements. Owners must make any additional measurements as determined by the AHJ.
