Scrubbers to be tested tomorrow

Update for Community Advisory Group About Kingston Fossil Plant

Scrubber Equipment Testing

October 28, 2009

Consistent with the information we provided you on October 19, the process of bringing the Kingston Fossil Plant scrubber unit online is continuing. As an update, tomorrow, the plant will be running pumps which will circulate water within the scrubber. Water from a one-million gallon tank will run through sprays and fountains, including a bed of 1700 fountains that shoot water 20 feet high.

Again, if the air is cool, the warmer water coming into contact with the cooler air will create a water vapor inside the scrubber that will likely exit the unit through the stacks. This water condensation is like the steamy water vapor that comes off the surface of the river when the air temperature cools below the water temperature.

There are still no furnaces operating and no coal is being burned. No flue gas has passed through the scrubber, and nothing will exit the stack other than water vapor. The scrubber has not started up; this is still scheduled for mid- to late November.

Equipment testing will continue until the scrubber starts up. You may see this vapor again, but we want you to know it is only water vapor.

We will give you plenty of notification prior to the scrubber going into service.

As always, let me know if you have questions. Thanks,
