NPDES Stormwater Permit NCS000589
Duke Energy Progress, LLC
Weatherspoon Steam Electric Plant
Robeson County
Dear Ms. Bednarcik:
On November 2, 2022, a site inspection was conducted for the Weatherspoon Steam Electric Plant located at 491 Power
Plant Road in Lumberton, North Carolina. A copy of the Compliance Inspection Report is enclosed for your review. Mr. Kent
Tyndall, Lead EHS Professional, and Mr. Ricky Stroupe, CCP Environmental Field Support, were present during the
inspection and their time and assistance is greatly appreciated. The site visit and file review revealed that the subject facility
is covered by NPDES Stormwater Permit NCS000589. Permit coverage authorizes the discharge of stormwater from the
facility to receiving waters designated as an unnamed tributary to the Lumber River and the Lumber River, class C;Sw
waters in the Lumber River Basin.
As a result of the inspection, the facility was found to be compliant with the conditions of NPDES Stormwater Permit
NCS000589. Please refer to the enclosed Compliance Inspection Report for additional comments and observations made
during the inspection.
Please be advised that violations of the NPDES Stormwater Permit are subject to a civil penalty assessment of up
to $25,000 per day for each violation. If you or your staff have any questions, comments, or needs assistance with
understanding any aspect of your permit, please contact me, at [phone] or via e-mail at [e-mail].
Sincerely,

Inspection Summary
Inspection conducted as part of the individual stormwater permit renewal process. Met with Kent Tyndall, Lead EHS
Professional, and Ricky Stroupe, CCP Environmental Field Support. Application for permit renewal has been submitted as
required. Based on review of the facility's monitoring records, facility was triggered into monthly monitoring of all parameters
under the current permit's Tier One response actions due to an exceedance of the benchmark value for TSS at outfall SW-2
in December 2018. Additionally, there was an exceedance of the benchmark value for Zinc in December 2019, TSS and
Copper in September 2020, and Copper in April 2022. Monthly monitoring has been conducted and recorded continuously
since December 2018 as there has not been three consecutive monitoring events with all results below benchmarks. For
several months in 2019 as well as late 2020 into most of 2021, 'No Flow' was recorded. It should be noted that there have
been no consecutive exceedances of any parameter. Analytical monitoring has only been conducted at outfall SW-2 as
outfall SW-1 has been determined to have only sheet flow and the drains leading to outfall SW-3 have been covered with
metal plates. In an attempt to determine what might be causing the sporadic exceedances, facility staff have evaluated the
weather conditions that occurred during the respective sampling events (large storms/hurricanes) and even tested the fines
associated with the available gravel that was purchased to place on parking and roadways after large storm events. Results
of the gravel fines testing, which were provided for review during the inspection, show extremely elevated levels of all
parameters; not just TSS, Zinc and Copper. Facility's SWPPP contains all necessary components and is reviewed/updated
on an annual basis. Documentation related to facility inspections, employee training, evaluations of the stormwater outfalls
for the presence of any non-stormwater discharges, listing of significant spills (none), effectiveness of BMPs, and
comparison of monitoring data to the benchmark values was also provided for review.
Regarding the facility's ash hauling activities; approximately 25 trucks enter and exit the facility twice per day, five days per
week. Facility staff estimate that ash hauling should be completed in approximately three more years.
After the records review, observations were made of the ASTs and other containers with secondary containment Trucks
hauling ash along the travel route as well as the catch basins leading to outfall SW-2 were also observed.
