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 9,451,013 pounds over 2003. Releases increased primarily due to the increased use of SCRs and the associated increase in sulfuric acid emissions. Changing the basis for estimations from model predictions to stack test data exacerbated the change as stack measurements yielded much higher SO3 concentrations. Apparently, both, the SCR catalyst oxidation of SO2 to SO3 and boiler production of SO3 are much higher than predicted.

⁴ “Off-site disposal” indicates ash used for such things as driveways and fill for industrial parks.

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.
