Subject: NPDES Permit Application
Wastewater Treatment Additive update
Marshall Steam Station
NPDES Permit NC0004987
Catawba County
Dear Dr. Chernikov,
In a submittal to NCDEQ dated August 22, 2017, Duke Energy updated it's NPDES
permit application including a list of chemicals that were to be used as part of Marshall
Steam Station Hazardous and Toxic Substances List. Below is a summary and
reasoning for this updated lists submittal.
Sodium Hydroxide (Caustic Soda) — The previously submitted table 5.1 lists "Caustic
Acid" which was a typo, and should have been listed as "Caustic Soda". This chemical
will be used in the new FGD WWTS, for pH adjustment in the Submerged Flight
Conveyors (SFCs), and for pH adjustment at the Retention and Holding Basins.
Sodium Carbonate (Soda Ash) — This will be used for pH adjustment in the Submerged
Flight Conveyors (SFCs).
Included in the submittal are the following:
• Updated Marshall Steam Station Hazardous and Toxic Substances Table 5.1
• The SDS sheets for Sodium Hydroxide and Sodium Carbonate.
