4. Instream Data Summary
Instream monitoring may be required in certain situations, for example: 1) to verify model predictions
when model results for instream DO are within 1 mg/l of instream standard at full permitted flow; 2) to
verify model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other
instream concerns. Instream monitoring may be conducted by the Permittee, and there are also
Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee (in
which case instream monitoring is waived in the permit as long as coalition membership is maintained).
If applicable, summarize any instream data and what instream monitoring will be proposed for this
permit action: NA.
Is this facility a member of a Monitoring Coalition with waived instream monitoring (Y/N): NA.
Name of Monitoring Coalition: NA.

5. Compliance Summary

Summarize the compliance record with aquatic toxicity test limits and any second species test results
(past 5 years): B_WET Testing_Self Monitoring Summary 4-2021 HQ 18.
Summarize the results from the most recent compliance inspection: [See Attachment
C_NC0021962_Compliance Evaluation Inspection_20201221_7p]

6. Water Quality-Based Effluent Limitations (WQBELs)
Dilution and Mixing Zones
In accordance with 15A NCAC 2B.0206, the following streamflows are used for dilution considerations
for development of WQBELs: 1Q10 streamflow (acute Aquatic Life); 7Q10 streamflow (chronic Aquatic
Life; non-carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH).
If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): NA.
If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): NA.
Oxygen-Consuming Waste Limitations
Limitations for oxygen-consuming waste (e.g., BOD) are generally based on water quality modeling to
ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits
(e.g., BOD= 30 mg/l for Municipals) may be appropriate if deemed more stringent based on dilution and
model results.
If permit limits are more stringent than TBELs, describe how limits were developed: NA.
Ammonia and Total Residual Chlorine Limitations
Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of
1.0 mg/l (summer) and 1.8 mg/l (winter). Acute ammonia limits are derived from chronic criteria,
utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non-Municipals.
Page 4 of 9

Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection
of aquatic life (17 ug/l) and capped at 28 ug/l (acute impacts). Due to analytical issues, all TRC values
reported below 50 ug/l are considered compliant with their permit limit.
Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: NA.
Reasonable Potential Analysis (RPA) for Toxicants
If applicable, conduct RPA analysis and complete information below.
The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality
standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent
effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC
RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero
background; 3) use of ½ detection limit for “less than” values; and 4) streamflows used for dilution
consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of
dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of
Instream Dissolved Metals Standards, dated June 10, 2016.
A reasonable potential analysis was conducted on effluent toxicant data collected between Sep2016 and
Feb2021 for Outfall 001. Pollutants of concern included toxicants with positive detections and associated
water quality standards/criteria. Based on this analysis, the following permitting actions are proposed for
this permit:
• There was no detection for the following parameters: Toluene, Benzene, Ethylbenzene,
Naphthalene, Xylene, MTBE. Monitoring for MTBE was requested to be removed because
MTBE has not been used in gasoline since the early 2000’s. In response to your request,
monitoring has been reduced from monthly to quarterly. No changes to monitoring for the others
parameters is recommended because they are parameters of concern for bulk-storage of petroleum
products.
• There was detection for the following parameter, but there was no reasonable potential to exceed
water quality standards, EPA criteria, nor in-stream target values: Total Phenolic Compounds.
The Predicted Max Concentration was < 50% of Allowable Concentration for this parameter. No
changes to monitoring for this parameter are recommended because this is a parameter of concern
for bulk-storage of petroleum products.
If applicable, attach a spreadsheet of the RPA results [See Attachment D_NC0021962 RPA 2021_7p] as
well as a copy of the Dissolved Metals Implementation Fact Sheet for freshwater/saltwater [Not
Applicable] to this Fact Sheet. Include a printout of the RPA Dissolved to Total Metal Calculator sheet if
this is a Municipality with a Pretreatment Program.
Toxicity Testing Limitations
Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in
accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits
issued to Major facilities or any facility discharging “complex” wastewater (contains anything other than
domestic waste) will contain appropriate WET limits and monitoring requirements, with several
exceptions. The State has received prior EPA approval to use an Alternative WET Test Procedure in
NPDES permits, using single concentration screening tests, with multiple dilution follow-up upon a test
failure.
Describe proposed toxicity test requirement: No changes for renewal. Whole Effluent Toxicity (WET) -
Acute (Fathead Minnow, 24-hour P/F), Annual [see Section A. (2.)].
Page 5 of 9

Mercury Statewide TMDL Evaluation
There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply with
EPA’s mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a
wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and
industrial facilities with known mercury discharges. Given the small contribution of mercury from point
sources (~2% of total load), the TMDL emphasizes mercury minimization plans (MMPs) for point source
control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (>1 ng/l) will
receive an MMP requirement. Industrials are evaluated on a case-by-case basis, depending if mercury is a
pollutant of concern. Effluent limits may also be added if annual average effluent concentrations exceed
the WQBEL value (based on the NC WQS of 12 ng/l) and/or if any individual value exceeds a TBEL
value of 47 ng/l
Describe proposed permit actions based on mercury evaluation: NA.
Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: Lake Wylie has TMDLs for Total Phosphorus and Total Nitrogen. Nutrients are not a
concern for Bulk-Storage Oil Terminals.
Other WQBEL Considerations
If applicable, describe any other parameters of concern evaluated for WQBELs: NA.
If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall
comply with in order to protect the designated waterbody: NA.
If applicable, describe any compliance schedules proposed for this permit renewal in accordance with
15A NCAC 2H.0107(c)(2)(B), 40CFR 122.47, and EPA May 2007 Memo: NA.
If applicable, describe any water quality standards variances proposed in accordance with NCGS 143-
215.3(e) and 15A NCAC 2B.0226 for this permit renewal: NA.

7. Technology-Based Effluent Limitations (TBELs)
Industrials (if not applicable, delete and skip to next Section)
Describe what this facility produces: bulk-storage of petroleum products
List the federal effluent limitations guideline (ELG) for this facility: NA.
If the ELG is based on production or flow, document how the average production/flow value was
calculated: NA.
For ELG limits, document the calculations used to develop TBEL limits: NA.
If any limits are based on best professional judgement (BPJ), describe development: See current Bulk-
Storage permitting strategy for discussion of TSS limits.
Document any TBELs that are more stringent than WQBELs: NA.
Document any TBELs that are less stringent than previous permit: NA.

Page 6 of 9

8. Antidegradation Review (New/Expanding Discharge):
The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not
degrade water quality. Permitting actions for new or expanding discharges require an antidegradation
review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit must
document an effort to consider non-discharge alternatives per 15A NCAC 2H.0105( c)(2). In all cases,
existing instream water uses and the level of water quality necessary to protect the existing use is
maintained and protected.
If applicable, describe the results of the antidegradation review, including the Engineering Alternatives
Analysis (EAA) and any water quality modeling results: NA.

9. Antibacksliding Review:
Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(l) prohibit
backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a
reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations
may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL
limits, or WQBELs may be less stringent based on updated RPA or dilution).
Are any effluent limitations less stringent than previous permit (YES/NO): No.
If YES, confirm that antibacksliding provisions are not violated: NA.

10. Monitoring Requirements
Monitoring frequencies for NPDES permitting are established in accordance with the following
regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2)
NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance,
Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best
Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not
considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti-
backsliding prohibitions would not be triggered by reductions in monitoring frequencies.
For instream monitoring, refer to Section 4.

11. Electronic Reporting Requirements
The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective
December 21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports
(DMRs) electronically. Effective December 21, 2020, NPDES regulated facilities will be required to
submit additional NPDES reports electronically. This permit contains the requirements for electronic
reporting, consistent with Federal requirements.

Introduction
You will find five separate tables in the worksheet tabs below. These tables are:
1- Determine the designated use(s) for the water body of concern.
3 - Read across the table to identify the available standards, criteria or in-stream target values once a parameter has been located.
Contacts - We are here to help. Please contact us with any questions and comments.
919-707-9016
Example
Parameter of concern = Carbon Tetrachloride (CAS 56-23-5)
Water body of concern = Mountain Creek (Yadkin Pee-Dee River Basin, Stream Index: 13-5-(0.7))
Step 1 - Determine the designated uses associated with Mountain Creek
Class WS IV (Water Supply)
The following information was found:
NC 02B Standards table:
Water Supply = 0.254 ug/L
Fish Consumption = 1.6 ug/L
EPA NRWQC table:
No information
NC In-Stream Target Values table:
Freshwater Aquatic Life = 560 ug/L
The most sensitive designated use for Mountain Creek is the Water Supply use. Therefore,
The Water Supply standard of 0.254 ug/L for Carbon Tetrachloride will be used.
Note: If the most protective value is not a NC 02B water quality standard, it is best to contact NC DWR Classifications &
Standards staff for more information.

1.2 - Identify all designated uses associated with the classification identified in step 1.1 by referring to the North Carolina Designated Uses for
Surface Waters table (orange tab in this workbook):
2 -Search the NC 02B Standards (green tab), EPA NRWQC (yellow tab), and NC In-Stream Target Values (blue tab) tables for the parameter(s) of concern.
2.1 - Search for chemicals by Chemical Abstracts Service (CAS) number. If you do not know the CAS number for the chemical of concern, a simple
google search should provide it.
Click here for an example of this process
Name For questions concerning:Email Phone
2.3 - Search for non-chemical parameters (pH, temperature, etc.) by name as they do not have CAS numbers.
2.2 - Chemicals can be searched for by name, but be advised that all known synonyms are not included in these tables. Searching by chemical name
may miss important information.
4 - The standards, criteria, and in-stream target values in these tables do not substitute for any written regulations, nor are they themselves regulations.
2.4 - Search all tables for each chemical or non-chemical parameter as different water quality standards, EPA recommended criteria, or NC in-
stream target values may apply for different designated uses.
3.1 - The most sensitive use must be protected. Refer to the designated uses table when deciding which standard, criteria, or in-stream target
values to apply.
3.2 - North Carolina Standards are established in rule (15A NCAC 02B) and take precedence over EPA national criteria. EPA national criteria have
undergone thorough scientific and national stakeholder evaluation, but have not been through the NC rule making process. EPA national criteria
take precedence over NC in-stream target values. NC in-stream target values are determined based on available toxicological data for chemicals per
language in Title 15A the North Carolin Administrative Code (15A NCAC 02B .0202 and .0208). Classifications & Standards staff should be contacted
for guidance on the use of these values.

The tables in this workbook detail the various water body classifications, surface water quality standards, criteria, and in-stream target values that
the State of North Carolina employs to protect the designated uses of its surface waters.
1 - North Carolina Designated Uses for Surface Waters (Designated Uses - orange tab)
2 - North Carolina 15A NCAC 02B Water Quality Standards for Surface Waters (02B Standards - green tab)
3 - Environmental Protection Agency Nationally Recommended Water Quality Criteria (EPA-NRWQC - yellow tab)
4 - North Carolina In-Stream Target Surface Waters (In-Stream Target Values - blue tab)
1.1 - Identify the classification associated with the water body of concern by referring to the NC Surface Water Classifications interactive map, river
basin classification schedules, and any NC Title 15A rules associated with the water body of concern.
5 - Supporting information such as footnotes, descriptions of acronyms, and references (Supporting Info - bright yellow tab)
River Basin Classification Schedules

North Carolina Designated Uses for Surface Waters
Surface Water Quality Standards, Criteria & In-Stream Target Values
Step 3 - Choose the most protective value from those identified in Step #2 to protect the most sensitive designated use.
Step 2 - Search for Carbon Tetrachloride, for each of the designated uses, in the NC 02B Standards, EPA NRWQC, and NC In-Stream Target Values
tables.
Determining what in-stream concentration of Carbon Tetrachloride would protect the uses in Mountain Creek. Other factors, such as dilution, may
need to be considered for determining permit limits.
Step 1.1 - The following classification for Mountain Creek was found using the online NC Surface Water Classifications interactive map
(see link above):
Step 1.2- The following designated uses were identified using the classification for Mountain Creek (See the designated uses table):

RE: Charlotte Terminal Draft NPDES Permit NC 0021962 Comments
FedEx— 7737 5400 5830
Dear Mr. Denard:
CITGO Petroleum is submitting a permit modification request for the draft NPDES permit
NC0021962. Regarding the sampling requirements as outlined in Section A. (1) Effluent
Limitations and Monitoring Requirements, CITGO is requesting MTBE be removed from the
monitoring requirements since MTBE has not been used in gasoline since the early 2000s, is not
used in any products stored onsite and has not been detected in NPDES monitoring for at least
the last 5 years and beyond. CITGO is also requesting that the sampling frequencies for EPA
Method 625 (semi-volatiles)be reduced from semi-annual monitoring to annual monitoring as all
semi-volatile monitoring parameters were undetected or below the Reported Detection Limit
RDL) for at least the last 5 years and beyond.
CITGO believes that through the implementation of stormwater Best Management Practices,
Spill, Prevention, Control and Countermeasure plan, routine equipment maintenance and
inspections, it has minimized the potential for pollutants to enter the stormwater. Additionally,
all products are contained in sealed tanks and hard piped to the loading rack, all rack stormwater
is contained in an aboveground storage tank and hauled offsite for treatment and terminal
personnel complete inspection of stormwater daily and prior to any discharge. As such, the
possibility of the tank dike area contributing pollutants to stormwater is minimal as highlighted
by our monitoring results.
CITGO appreciate you taking these requests under consideration. If you have any questions or
need additional information,please feel free to contact me at(484) 587-6524.
