PM10 did exceed the federal health standard again yesterday. Over the weekend, we do expect some improvement with less dust generating work activities. Therefore, we are dropping the risk level to Low. On Monday, we expect a Moderate dust risk to return with calm conditions and a return to the work week. Then on Christmas Eve and Christmas Day, we are forecasting a Low dust risk due to better ventilation from a tough moving through, as well as less dust generating work activity over the holiday.
