Re: Compliance Stormwater Evaluation Inspection
Dear Mr. Ruettgers:
On September 1, 2022, the U.S. Environmental Protection Agency Region 4, Mecklenburg County, and
the North Carolina Department of Environmental Quality (NCDEQ) conducted a Compliance
Stormwater Evaluation Inspection (CSWEI) at the Southern Cast facility. The purpose of the CSWEI
was to evaluate your compliance with the requirements of Sections 301 and 402(p) of the Clean Water
Act (CWA), 33 U.S.C. §§ 1311 and 1342(p); the regulations promulgated thereunder at 40 C.F.R.
§ 122.26; and the NCDEQ National Pollutant Discharge Elimination System industrial stormwater
general permit NCG03.
The EPA recommends that you reach out to Mr. Danny Smith at NCDEQ, at dannv.smith( ,ncdenr.eov
to discuss your permitting requirements. The EPA and NCDEQ appreciate your cooperation in
conducting this CSWEI. Enclosed is the EPA's CSWEI report, which includes EPA's observations. If
you have any questions regarding this inspection report, please contact Mr. Mark Robertson by email at
robertson.mark(aepa.eov or at [phone].

RE: NPDES Permit Application
Southern Cast
901 N. Church Street
Charlotte, NC 28299
F&R Proposal No.: 2259-00702
Dear Sir or Madam:
Froehling & Robertson, Inc. (F&R) on behalf of Southern Cast (the Client) is pleased to submit this National
Pollution Discharge Elimination System (NPDES) NCG030000 Notice of Intent for inclusion in the
Stormwater General Permit. The Subject Property is located at 901 North Church Street in Charlotte,
Mecklenburg County, NC.
The United States Environmental Protection Agency (EPA) issued a letter dated October 28, 2022 based
on their compliance inspection of the facility on September 1, 2022. Based on their compliance inspection
the EPA indicated that a NPDES permit appears to be required for the facility. The EPA identified several
potentials for discharge to stormwater via inlets located on the Subject Property. A copy of the
correspondence and Inspection Report is attached to this Application. The EPA recommended that
Southern Cast contact the North Carolina Department of Environmental Quality (NCDEQ), specifically Mr.
Danny Smith, in regards to the permitting requirements for this facility for an NPDES Industrial Stormwater
General Permit (NCG03). F&R, on behalf of Southern Cast, spoke with Ms. Britney Carson and Mr. Danny
Smith of the NCDEQ on November 15, 2022. They confirmed that NPDES Industrial Stormwater General
Permit (NCG03) would be the appropriate permit, and the sample locations should correlate to the outfalls
identified in the EPA Inspection Report. F&R indicated they would be assisting Southern Cast with the
application and would be conducting a site walk to examine the outfalls and facility and invited the NCDEQ
to accompany F&R. The NCDEQ indicated they would not need to be present and that they had the EPA's
report.
F&R did a site walk on December 5, 2022 to examine the facility and outfalls. And has incorporated that
information into this application. The drop inlet by the railroad tracks identified in Page 11 of the EPA
Inspection Report does not receive run-off from the facility. This inlet was installed by the railroad in their
right of way to manage run-off that could impact the rail line; therefore, F&R has not proposed sampling
associated with this drop inlet.
F&R proposes quarterly sampling for the following parameters in accordance with the General Permit
requirements:
• Total Suspended Solids (TSS)
A Minority -Owned Business

9
• pH (Field Measurement at collection)
• Chemical Oxygen Demand (COD)
• Total Lead, Total Zinc, and Total Copper
• Oil & Grease (Method 1664)
• Total Rainfall at time of Sampling Event (as reported at Mecklenburg County CRN1S)
Please do not hesitate to contact us if you have any questions or require further information, or if you
would like to discuss the sampling parameters and locations.
Sincerely,
FROEHLING & ROBERTSON, INC.
