In response to questions about quarry work, TVA received this answer from the Harriman Quarry last week.

The Roane County quarry did not crush during the month of October. They started back Monday November 2nd with a shift running at night. The purpose of running at night is to allow the crew to do their maintenance work during the daylight hours.
They are currently making several changes at the quarry. They are in the process of enclosing the crushing plant in order to drastically reduce the noise of crushing. In addition they are replacing the back up alarms with strobe lights on all the equipment on the yard so there will no longer be warning beeps when a piece of equipment is backing up.
This schedule was developed as part of the normal operating plan and does not have anything to do with TVA. They plan to continue this schedule for the foreseeable future.
Let me know if you have any questions or need further information.
