Section 675.009 - Required Corrective MeasuresIf an air sample taken in accordance with the requirements of 105 CMR 675.000 reveals that the air level of carbon monoxide or nitrogen dioxide exceed the correction air levels of 105 CMR 675.008(A), the operator shall take both immediate corrective measures as described in 105 CMR 675.009(A) as well as one or more appropriate long term measures as described in 105 CMR 675,009(B).
(A)Immediate Corrective Measures. The operator shall immediately take steps to increase the ventilation in the indoor skating rink through any appropriate and safe means, and shall continue to ventilate the indoor skating rink at above normal rates or through extraordinary means until such time as a subsequent air sample taken by the operator reveals that air levels of carbon monoxide or nitrogen dioxide are below the correction air levels of 105 CMR 675.008(A). The operator shall take one or more follow-up air samples in intervals of 20 minutes or less after the taking of any sample which had revealed an exceedance of the correction air levels of 105 CMR 675,008(A) until such time as a follow-up air sample reveals that the air level of the contaminant(s) for which there was an exceedance have been reduced below the correction air levels of 105 CMR 675.008(A). The operator shall record the results of each follow-up air sample in the Record Keeping Log as well.(B)Long Term Corrective Measures. The operator shall, as soon as reasonably practical, take one or more of the following steps to eliminate the problem which resulted in an exceedance of the correction air levels of 105 CMR 675.008(A) and to prevent any future exceedances of these levels: (1) increase ventilation (the rate of exchange of outdoor and indoor air) at the skating rink;(2) begin warming up ice resurfacer equipment outside the building;(3) install a local exhaust system in area where resurfacing equipment is warmed up to vent exhaust to the outside;(4) retune or repair resurfacing equipment and then continue to regularly retune and repair the equipment as recommended by the manufacturer.(6) replace edging equipment with equipment having lower emissions;(7) install a vertical exhaust pipe the top end of which protrudes above the highest point of the ice resurfacer;(8) install a catalytic converter on resurfacing equipment;(9) install an oxygen sensor in resurfacing equipment to regulate fuel leanness or richness;(10) decrease resurfacing schedule to reduce amount of exhaust gases emitted;(11) convert the existing resurfacing equipment to electric power or acquire replacement electrically powered resurfacing equipment; and/or(12) take other action which has the effect of reducing or helping reduce air levels of carbon monoxide and nitrogen dioxide to required levels.
