1 Air indicates emissions that come out of the stack.
2 Water indicates emissions that have been placed in an on-site holding pond and then discharged to the local waterway following all state and local permit requirements.
3 Land indicates ash that has been put in ponds or stacked dry in a pile on-site.
4 Off-site disposal indicates ash used for such things as driveways and fill for industrial parks.
5 Total 2004 releases represent a decrease of 1,100,866 pounds from 2003. Releases decreased primarily due to a decrease in the amount of coal combusted and a significant switch to western coal.
