2/7/2011	Bill Bertie sent an e-mail stating that the flow meter was repaired and returned to service at 1:19pm on 2/4/11	GLENN CARPER
2/4/2011	Bill - Wanted to let you know that we are having problems with the stack flow meter for the CEMS unit. The air line between the probe and the monitor froze. When we went to replace the line we broke a connector on one end. We don't have a replacement on hand. We ordered a new connector and hope to have it delivered in a day or two. The line will be repaired as soon as possible. In the meantime we don't have any stack gas flow data. I think the CEMS uses the last good flow reading to calculate mass emission rates. How are we suppose to fill in missing data? Glenn - You'll have to ask Mark Stone that question. I will note your call for the record.	GLENN CARPER
