Ms. Wang,

In response to your question regarding the groundwater references that were removed from Pages 2, 3, a nd 9 of the original draft, SCE&G has opted to close Ash Pond 1 mainly due to its desire to c onvert from wet to dry handling of fly ash and bottom ash, increase the potential for ash recycling, and in anticipation of future federal regulations.

Please feel free to contact me at the noted numbers or by e-mail at mferguson1@scana.com<mailto:mferguson1@ scana.com> if you have any other questions.

Sincerely,

Mark
