Facility Summary
This facility discharges 100% industrial wastewater. This facility serves a Surface -Water Pollution Control
System for stormwater in proximity to above -ground storage tanks (ASTs) for surface bulk -storage of
ethanol and petroleum hydrocarbon fuels with capacity exceeding one million gallons, and fuel -truck
loading racks. This facility utilizes the following treatment units:
• Oil -water separator (10,000-gal)
• Two (2) holding tanks (10,000-gal each)
• Bermed secondary containment for ASTs
• Final holding pond (currently 160,000 gallons) with hand -operated discharge valve (normally
closed)
Renewal Summary
This renewal contains the following proposed changes:
• Reduced the monitoring frequency to Annually for Acute Toxicity testing in the effluent table in
Section A. (1.) as the facility has passed all toxicity tests within the last five years, per the Sept
2005 Guidance on Petroleum Bulk -Storage.
• Increased the monitoring frequency to Monthly for MTBE in the effluent table in Section A. (1.) as
the parameter was detected upon review of the DMR data from the past five years. Per the Sept
2005 Guidance on Petroleum Bulk -Storage facilities, footnote #7 has been added to Section A. (1.)
requiring that an action plan to reduce MTBE be submitted within 12 months of the permit effective
date.
• Removed the Turbidity limit in the effluent table in Section A. (1.) as recent data did not show a
reasonable potential to exceed water quality standards. Per the Sept 2005 Guidance on Petroleum
Bulk -Storage facilities, the most recent two years of data were used in the RPA. Monitoring kept at
Monthly to remain consistent with other permitted terminal facilities.
• Added footnote #3 for Oil & Grease to the effluent table in Section A. (1.), per the 2005 Guidance
on Petroleum Bulk -Storage facilities.

DocuSign Envelope ID: 4C2BE7DC-0B7A-4556-9DF0-1DF967B3D8AD
• Updated the language in Section A. (2.) to include the new electronic submission information for
testing results.
• Updated Section A. (4.) Electronic Reporting of Discharge Monitoring Reports to reflect current
federal requirements.
Compliance History
Charlotte Terminal (West) has had no enforcements since 1993. Most recent inspection (February 2020)
showed the facility to be in compliance. One NOD issued in 2018 for TSS limit exceedance.
Whole Effluent Toxicity (WET) Testing
In accordance with current permitting strategies for Petroleum Bulk -Storage facilities (see Sept 2005
Strategy), WET testing is required in this permit as Acute Annual toxicity monitoring [TAE6C] with
Fathead Minnow (Pimephales promelas).
This facility has passed every annual test during the past five years (April 2016-April 2021).
RPA for Bulk Storage (2016 Generic RPA for non -hardness dependent)
A flow (Qw) of 0.2298 MGD was used, as it is the maximum, monthly average flow during the past four
years (April 2017- April 2021).
A reasonable potential analysis was conducted on effluent toxicant data collected between September 2016
and April 2021. Based on this analysis, the following permitting actions are proposed for this permit:
• Benzene — no detects; monitoring kept at monthly per current permitting strategy for Petroleum
Bulk -Storage facilities
• Toluene — no detects; monitoring kept at quarterly to remain consistent with previous permit and
other permitted terminal facilities
• Ethylbenzene — no detects; monitoring kept at quarterly to remain consistent with previous permit
and other permitted terminal facilities
• Xylenes Mixture — no detects; monitoring kept at quarterly to remain consistent with previous
permit and other permitted terminal facilities
• Napthalene — no detects; monitoring kept at quarterly to remain consistent with previous permit
and other permitted terminal facilities
• MTBE — detected; no reasonable potential to exceed water quality standards; predicted max < 50%
of allowable concentration; monitoring increased to monthly per current permitting strategy for
Petroleum Bulk -Storage facilities
• Phenolic Compounds — no reasonable potential to exceed water quality standards; predicted max <
50% of allowable concentration; monitoring kept at monthly per current permitting strategy for
Petroleum Bulk -Storage facilities
• Turbidity — no reasonable potential to exceed water quality standards; predicted max > 50% of
allowable concentration; current limit will be removed from the permit and monitoring kept at
monthly per current permitting strategy for Petroleum Bulk -Storage facilities
Monitoring will be retained in the permit for all parameters per current permitting strategy.

describe the processes that generate wastewaters. If the space provided is not sufficient attach a
separate sheet of paper with the system description.
The facility does not have any treatment system or treatment assets associated with the

structures with normally closed valves. Stormwater gravity clarifies within containments and
sediment basin before infrequently discharging thru one containment valve (outfall 001) as
necessary for water management. Very infrequently, (annually or less in most instances)
hydrostatic test wastewaters convey by the same system and retention occurs for a period of
time as necessary to dissipate total residual chlorine before discharge thru the same outfall.
In rare instances chemical dechlorination may be used to achieve chlorine removal. Contact
stormwater reaching the truck loading rack is conveyed to an in -ground separator/ sump and
then to a holding tank before off -site recycling, treatment and disposal by third -party facilities.
Tank water bottoms are also removed to the same third -party facilities.

Subject: RE: DRAFT Permit Renewal for Charlotte Terminal (NC0046213)
Date: Friday, August 13, 2021 3:20:06 PM
Sydney,
I appreciate the opportunity to review the subject draft NPDES permit and have included my
response below in bold to satisfy the new paperless standards.
I concur with issuance of the above permit as I have no appreciable expertise in implementation
of the Clean Water Act requirements and have minimal understanding of the information
provided. As a result, I have no basis for opposing the permit.
Please also note that the nearest downstream raw water intake for a public water system is
associated with the City of Belmont and is located approximately 9.9 miles downstream.
If you have any questions or need any additional information, please let me know.
Thanks,
Clint

Hello,

DocuSign Envelope ID: 4C2BE7DC-0B7A-4556-9DF0-1 DF967B3D8AD
Requesting comments on the draft permit for Charlotte Terminal (NC0046213). This is a PC-1
facility in Mecklenburg County. It was submitted for Public Notice on July 13, 2021.
Please send any comments to me by August 13, 2021.
Mr. Cook,
We used to send a separate approval memo for the review by Public Water Supply. Since
we're moving to paperless documents, your email comments will take the place of the
old DEH/PWS memo. Thanks for your help with this.
Thanks,
