RE: Discharge Monitoring Reports
September-December,2025
OmniSource, LLC—Fayetteville
COC No.NCG200366
To whom it may concern:
Please find enclosed with this submittal the September thru December,2025 Discharge Monitoring
Reports (DMRs) for our OmniSource, LLC facility in Fayetteville (Cumberland County). No
stormwater samples were collected and/or analyzed during September, October, or November due
to no discharge. However,stormwater was collected and analyzed during a rain event in December
2025. The following DMRs are included in this submittal:
September 2025—No Discharge DMR
October 2025—No Discharge DMR
November 2025—No Discharge DMR
December 2025—DMR with Analytical
OmniSource submitted these DMRs on February 18, 2026 to the Division of Water through their
electronic upload portal. The attached DMRs include original signatures. If you have any questions
regarding this submittal, please contact me via phone [phone]) or by e-mail at
[e-mail].

Dear Mr. Anderson:
As authorized by acceptance of the ECS Southeast, LLC(ECS) Proposal 49-48388P dated December 19, 2024, ECS has
completed a December 2025 National Pollutant Discharge Elimination System (NPDES) stormwater sampling event
for the above referenced site. The Stormwater Discharge Outfall (SDO) Qualitative Monitoring Reports for Outfall
(OF) Numbers 2, 4, 5, and 6 are attached. The sampling event was conducted on December 2, 2025 within the
first 30 minutes of an approximate 1.25-inch recorded rainfall event. SDO Qualitative Monitoring Forms and photo
documentation for sampling Outfall Numbers 2, 4, and 6 are included as an attachment.
Stormwater samples (sample IDs: OF-2, OF-4, OF-5, and OF-6)were collected and submitted for analysis by EPA
Method 1664B for Oil and Grease, EPA Method 200.7 for Copper (Cu), Lead (Pb), and Zinc (Zn), Standard Method
5220D-2011 for chemical oxygen demand (COD) and EPA Method 2540D-2015 for total suspended solids(TSS).
We appreciate the opportunity to provide our services. If there are questions regarding this report, or a need for
further information, please contact us.
Respectfully submitted,

A"measurable storm event" is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period,and the permittee obtains approval from the local DEMLR
Regional Office.

QUALIFIERS
Project: OmniSource Fayetteville-Storm
Pace Project No.: 92832345
DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
ANALYTE QUALIFIERS
R1 RPD value was outside control limits.
