All,
I wanted to follow up on a phone message I left you all this morning.
Yesterday (5/21/19) at approximately 2:30PM, PNG experienced a loss of HDD returns into Stream 4 (Troublesome
Creek) on the Line 446 Belews Creek Pipeline Project.
The stream in question is already impacted by a beaver dam that has diverted flow into a separate channel. As a result,
onsite crews were able to isolate the drilling fluids into the dry channel and impounded them with coconut wattles and
sand bags.
See picture attached referencing HDD fluids being isolated.
The onsite team tracked the stream downstream and the turbidity dissipated just past the ROW.
Volume = 1,000 gallons +/-
HDD Fluid = Bentonite and Water
Station Number= 412+10
A 5 day follow up letter will be sent out by Friday afternoon (5/24/19), but feel free to call me with any questions or
concerns.

Inadvertent Release of Drilling Mud
Rockingham County, NC
ESC Permit-Rocki-2019-013
Dear Mr. Leonard,
Duke Energy Corporation
4720 Piedmont Row Drive
charlotte, NC 28210
Please accept this letter as written notification of an inadvertent release of drilling mud to waters
of the US on May 21, 2019 from Horizontal Directional Drilling related to Line 446 project. The
release's location was into a tributary of Troublesome Creek in Rockingham County, NC.
The release, which consisted of Bentonite and Water, occurred at 2:30 pm on May 21, 2019
impacted Troublesome Creek and connecting tributary. The volume of this release to the dry
creek bed was approximately 1000 gallons. Duke Energy made a verbal notification to Division
of Water Resource —Winston Salem Regional Office at 10:15am on May 22, 2019. The crew
stopped drilling immediately and started coordinating with Duke Energy Environmental
Personnel to contain and mitigate the release. Below are specific remedial actions we have
taken:
• Installed sand bags and wattles to prevent further migration of Bentonite and Water.
• Implemented use of a vac truck to remove accumulated material in the dry tributary.
• The impacted area is currently being monitoring and plans have been put in place to
reduce potential for IR once drilling resumes. Intent is to capture further surface release
of drilling fluids in a closed loop system.
We will continue to focus on implementing BMPs relative to horizontal directional drilling and
implementation of the Inadvertent release contingency plan to reduce the potential for further
adverse environmental impact.
If you have any questions or wish to discuss in further detail, please contact Brad Loveland
Environmental Specialist at [phone].

Sincerely,
Ned Dietrich
