Hi Stephanie,

This email is a follow up to the voice mail I left you a few moments ago. The Mayo Steam Station will
report a daily permit limit exceedance for thallium at outfall 002. Our permit limit is 2.0 ug/L daily
max and we received a result of 2.67 ug/L for the November 15th sample. The station had recently
undergone some planned maintenance and we think this increase is from that work. Please let me
know if you have any questions. Thanks
