Dear Mr. Holland:

On November 14, 2023, Daniel Boss with the Division of Water Resources - Asheville Regional Office, received
notification that an estimated one gallon of pitch and oily debris from the pitch trap of building 55 reached Silver
Creek (11-34-6.5; Class WS-IV) at the SGL Carbon facility in Morganton. The incident occurred after plumbing
contractors were jetting 180 feet of underground stormwater line that was clogged. The release of the clog
allowed the oily debris and pitch to migrate from the malfunctioning pitch trap to the creek. Staff from the facility
immediately followed the facility’s release procedure and installed booms in the weir. Stephen Richards (Site
Environmental, Health & Safety Representative) indicated that a contractor arrived on-site the same day to clean
the remainder of the pitch and oily water from the pitch trap and inspect all other traps on site to ensure they are
working correctly. SGL Carbon caused an illegal discharge of oil & grease into Silver Creek, and the following
violation was identified:
