Briefly describe the proposed permitting action and facility background:
Norfolk Southern Railway Company applied to renew their permit to treat industrial wastewater
generated from shops at the Linwood Yard facility and stormwater, which consists of runoff (stormwater)
from the fueling track, fuel offloading area, and petroleum storage tank containment areas (SIC 4011 -
Railroads, Line-Haul Operating). The SIC code for Petroleum Bulk Stations and Terminals is 5171.
DocuSign Envelope ID: 261D4171-FCD1-4FFD-949F-D9C24F931907
Page 2 of 9

The petroleum bulk storage consists of a 2,000,000-gallon tank of diesel fuel according to a site plan
submitted on January 22, 2014. The SIC code for Petroleum Bulk Stations and Terminals is 5171.
In prior versions of this permit (2004) stormwater was permitted with internal outfalls 001 through 010.
These outfalls were removed from the 2009 version of the permit. The factsheet for the 2009 version of
discussion of separating water quality permitting into wastewater and stormwater permits. However, little
to no detail was given about what Outfalls or drainages would be permitted under the stormwater permit
and why outfalls 001 and 010 where removed on an individual basis. The 2009 final permit cover letter
indicated that there were no changes to the facility. Since the application indicates that stormwater is
being directed to the wastewater treatment plant, it would be assumed that runoff from activities formally
covered by monitoring outfalls 001 through 010. Ultimately, the WWTP discharges treated wastewater
and stormwater via Outfall 011. Moreover, facility does hold a stormwater permit NCG080842 (Transit
and Transportation, SICs 40-43) with DEMLR for an Outfall 001. Presumably, this stormwater covered
under NCG080842 is not directed to the WWTP. Flow from this stormwater does not appear to be
directed to the WWTP.
The railyard and maintained shops employee 190. No products are produced at this facility. Activities at
the facility include locomotive fueling and lubrication, locomotive and railcar maintenance and
repair, and railcar classification. The principal raw materials consumed are diesel fuel (95,000 gpd) and
lube oil (160 gpd). Boron treated cooling water used in the locomotives is also discharged (2004
Factsheet). The frequency of the discharge form Outfall 011 is intermittent for a variable number of days
per week. The monthly average stormwater discharge is 230,000 gpd. The monthly average discharge
from the wastewater and shop drainage is 25,700. [See Permit Application Attachment A]

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: No changes are proposed.

Is this facility a member of a Monitoring Coalition with waived instream monitoring (Y/N): No.

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.
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:
Not monitored, NA.

Page 5 of 9

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 Apr2014 to
Mar2019. 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:
For Total Phenolic Compounds there was no reasonable potential to exceed the allowable concentration
of 2,192.7 µg/L. The maximum predicted concentration is 37.5 µg/L. The recommended action is to
continue quarterly monitoring of Total Phenolic Compounds as these are pollutants of concern for this
industry.
If applicable, attach a spreadsheet of the RPA results [See Attachment E; NC0029246 RPA Spreadsheet
Summary] 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: The permit renewal will maintain Acute Toxicity
(Ceriodaphnia dubia): pass/fail; permit limited; at 90%; March, June, September, and December [See A.
(2)].

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
DocuSign Envelope ID: 261D4171-FCD1-4FFD-949F-D9C24F931907
Page 6 of 9

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: No monitoring. Mercury is not a
pollutant of concern.

Other TMDL/Nutrient Management Strategy Considerations
If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation
within this permit: NA.

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)
The facility is not categorical. No categorical TBELS apply.

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
DocuSign Envelope ID: 261D4171-FCD1-4FFD-949F-D9C24F931907
Page 7 of 9

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.
