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 an increase of 377,134 pounds over 2003. Releases increased primarily due to an increase in the disposal on-site of combustion by-products.

5 Total 2003 releases represent an increase of 208,337 pounds over 2002. Releases increased primarily because more coal was used and more slag remained onsite. Offsite waste transfers increased because more solid and hazardous waste was shipped offsite for disposal.
