Island Lake, NC Facility Summary Motiva Enterprises, LLC / Charlotte North Terminal (Motiva) is a minor discharger (<1 MGD) collecting and discharging stormwater as a component of its Surface -Water Pollution Prevention Plan. This plan manages stormwater in proximity to bulk -storage of petroleum hydrocarbons stored in aboveground storage tanks (ASTs). Motiva produces no products. This a storage terminal for gasoline, ethanol, and petroleum distillates. Facilities include ASTs exceeding one million gallons of various fuels servicing a fuel -truck loading rack. Significant changes to this facility are planned for permit renewal include the permittee's addition of discharge from a GW-REM system. Treatment facilities contributing to Outfall 001 consist of: • bermed secondary containment for ASTs; a detention pond including a discharge line fitted with hand -operated valve (normally closed) for combining stormwater and GW-REM effluent • oil/water separator and waste holding tank (truck -loading rack); residuals of holding tank hauled offsite for recycling • a groundwater remediation system (GW-REM) consisting of a dual -phase extraction system with carbon filtration; an intermittent discharge estimated not to exceed 1,000 gpd or 365,000 gallons per year. Receiving Stream - Discharge from WWTP for Outfall 001 is into an unnamed tributary to Gum Branch [Stream Segment 11-120-5]. The segment is not list in the 2018 North Carolina Integrated report or 303(d) list.

Whole Effluent Toxicity (WET) - The Permittee's application to renew requests relaxing Quarterly monitoring to Annually. However, DWR has deemed annual WET testing insufficient to evaluate toxicity and has set Quarterly WET tests as a minimum frequency. Therefore, all permits statewide with annual testing will be converted to Quarterly at renewal. Motiva does not perform Chronic [TGP3B] (Ceriodaphnia dubia) typically required for groundwater remediation (GW-REM) wastestreams deemed complex and continuous. Motiva combines GW-REM with stormwater and manages its discharges as manually controlled, episodic. Consequently, DWR's Aquatic Toxicity Branch (ATB) continues to recommend an Acute Toxicity 24-hour static test (Ceriodaphnia dubia) Pass/Fail limited as a Quarterly grab sample, during the months of January, April, July, and October [see section A. (1.)]. This facility has passed all toxicity monitoring over the past eight years. Compliance History- BIMS has no record of permit violations for the period Jan2017 thru Feb2021. Reasonable Potential Analysis (RPA) - In accord with current permitting guidance, renewal conducted RPAs using the "highest monthly average flow" during the previous permit cycle. DWR considered this conservative to protect the surface -water environment. Motiva's highest monthly flow was reported in December 2020 as 0.6199 MGD (see Table 3). The Division used this flow for renewal RPA calculations. Based on analytical databases reported on DMRs for the past three (3) years (Feb2018-Dec2020), DWR conducted an RPA for BTEX [benzene, toluene, ethylbenzene, Total Xylenes], naphthalene, Total Recoverable Phenolics, Turbidity, and MTBE (See RPA summary). The parameters Total Manganese, Total Iron have no standard therefore were not included in the RPA, but because this facility discharges to a water supply (WS-IV), manganese monitoring will continue, no limit. Turbidity was evaluated for its potential to exceed 50NTU. It did not show reasonable potential, but because the maximum predicted [32 NTU] is greater than 50% of the allowable concentration, monitoring will continue Monthly, no limit. Renewal Summary - DWR updated the following: • Total Iron is no longer a parameter of concern (POC). Monitoring is hereby discontinued. • Total Manganese monitoring continues Monthly (limit removed) considering a discharge to waters classified Water Supply (WS-IV). Fact Sheet Renewal Jun2021 -- NPDES NC0022187 Page 3 • Turbidity removed limit; monitoring continues Monthly. • BTEX (benzene, toluene, ethylbenzene, and total xylenes) were not detected during the previous permit cycle, and data do not show reasonable potential (RP) to exceed respective surface water -quality standards. However, BTEX remain parameters of concern (POCs) for petroleum bulk storage facilities. Therefore, monitoring will continue but at a frequency reduced from Monthly to Quarterly. Benzene, however, is a carcinogen, here further evaluated for its potential to impact water supply (WS-IV). Its permit limit is hereby removed based on no RP but monitoring continues Monthly. • EPA Method 625 monitoring continues Semi -Annually as a spot check for additional POCs related to GW-REM. • MTBE — The Permittee discontinued using this fuel additive years back and therefore it may only appear in local discharges as a component of onsite GW-REM. Furthermore, the Permittee mixes its GW-REM discharges with ponded stormwater for episodic discharge. Finally, data do not show reasonable potential, therefore monitoring for MTBE is discontinued for permit renewal.

However, application of the dissolved and hardness -dependent standards requires additional consideration in order to establish the numeric standard for each metal of concern of each individual discharge. The hardness -based standards require some knowledge of the effluent and instream (upstream) hardness and so must be calculated case -by -case for each discharge. Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45 (c). The discharge -specific standards must be converted to the equivalent total values for use in the RPA calculations. We will generally rely on default translator values developed for each metal (more on that below), but it is also possible to consider case -specific translators developed in accordance with established methodology. RPA Permitting Guidance/WQBELs for Hardness -Dependent Metals - Freshwater The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern, based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable standards and the critical low -flow values for the receiving stream. If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases. If monitoring for a particular pollutant indicates that the pollutant is not present (i.e. consistently below detection level), then the Division may remove the monitoring requirement in the reissued permit. 1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the following information: • Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically calculates the 1Q10 using the formula 1Q10 = 0.843 (s7Q10, cfs) a993 • Effluent hardness and upstream hardness, site -specific data is preferred • Permitted flow • Receiving stream classification 2. In order to establish the numeric standard for each hardness -dependent metal of concern and for each individual discharge, the Permit Writer must first determine what effluent and instream (upstream) hardness values to use in the equations. The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any hardness data and contacts the Permittee to see if any additional data is available for instream hardness values, upstream of the discharge. If no hardness data is available, the permit writer may choose to do an initial evaluation using a default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively. Fact Sheet Renewal Jun2021 -- NPDES NC0022187 Page 6 If the use of a default hardness value results in a hardness -dependent metal showing reasonable potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and upstream hardness samples over a period of one week. The RPA is rerun using the new data. The overall hardness value used in the water quality calculations is calculated as follows: Combined Hardness (chronic) = (Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) x (s7Q 10, cfs *Avg. Upstream Hardness, mg/L) (Permitted Flow, cfs + s7Q 10, cfs) The Combined Hardness for acute is the same but the calculation uses the 1 Q 10 flow. 3. The permit writer converts the numeric standard for each metal of concern to a total recoverable metal, using the EPA Default Partition Coefficients (DPCs) or site -specific translators, if any have been developed using federally approved methodology. EPA default partition coefficients or the "Fraction Dissolved" converts the value for dissolved metal at laboratory conditions to total recoverable metal at in -stream ambient conditions. This factor is calculatedusingthe linear p artition coefficients found in The Metals Translator: Guidance for Calculating a Total Recoverable PermitLimit from a Dissolved Criterion (EPA 823-B-96-007, June 1996) and the equation: Cai55 = 1 Crota1 1 + { Kpo] [sso+a)] [10-6] } Where: ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L used, and Kpo and a =constants that express the equilibrium relationship between dissolved and adsorbed forms ofmetals. A list of constants used for ea chhardness-dependent metal can also be found in the RPAprogramundera sheet labeledDPCs. 4. The numeric standard for each metal of concern is divided by the default partition coefficient (or site -specific translator) to obtain a Total Recoverable Metal at ambient conditions. In some cases, where an EPA default partition coefficient translator does not exist (ie. silver), the dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is dissolved to the same extent as it was during EPA's criteria development for metals. For more information on conversion factors see the June, 1996 EPA Translator Guidance Document. Fact Sheet Renewal Jun2021 -- NPDES NC0022187 Page 7 5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration (permit limits) for each pollutant using the following equation: Ca = (s7Q 10 + Qw) (Cwqs) — (s7Q 10) (Cb) Qw Where: Ca = allowable effluent concentration (µg/L or mg/L) Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L) Cb = background concentration: assume zero for all toxicants exceptNH3* (µg/L or mg/L) Qw = permitted effluent flow (cfs, match s7Q 10) s7Q 10 = summer low flow used to protect aquatic life from chronic toxicity and human health through the consumption of water, fish, and shellfish from noncarcinogens (cfs) * Discussions are on -going with EPA on how best to address background concentrations Flows other than s7Q10 may be incorporated as applicable: 1 Q 10 = used in the equation to protect aquatic life from acute toxicity QA = used in the equation to protect human health through the consumption of water, fish, and shellfish from carcinogens 30Q2 =used in the equation to protect aesthetic quality 6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern. Data entered must have b een taken within four and one-half years prior to the date of the permit application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper concentration of each pollutant. The Predicted Max concentrations are compared to the Total allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds the acute or chronic Total allowable concentrations, the discharge is considered to show reasonable potential to violate the water quality standard, and a permit limit (Total allowable concentration) is included in the permit in accordance with the U.S. EPA Technical Support Document for Water Quality -Based Toxics Control published in 1991. 7. When appropriate, permit writers develop facility specific compliance schedules in accordance with the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss on 40 CFR 122.47 Compliance Schedule Requirements. 8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and hexavalent chromium Water Quality Standards. As a cost savings measure, total chromium data results may be used as a conservative surrogate in cases where there are no analytical results based on chromium III or VI. In these cases, the projected maximum concentration (95th %) for total chromium will be compared against water quality standards for chromium III and chromium VI. 9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are inserted into all permits with facilities monitoring for hardness -dependent metals to ensure the accuracy of the permit limits and to build a more robust hardness dataset.

This petroleum bulk storage and distribution facility discharges stormwater under NPDES Permit No. NC0022187 which will expire on June 30, 2020. Enclosed is a copy of the Permit Renewal Application Form — Short Form C — Minor Industrial, a flow diagram of the wastewater system, a map of the facility location and surrounding area, and effluent data for the last three years. There is no change at the facility since the 2015 permit renewal, and Motiva is respectfully making the following requests for this permit renewal: Reduce monitoring frequency for BTEX and Naphthalene Motiva is respectfully requesting reduced monitoring for BTEX (Benzene, Toluene, Ethyl Benzene and Xylene) and Naphthalene based on the facility's exceptional performance for the past three years. All monitoring results for BTEX and Naphthalene were below the limits of detection (LOD) except for one sample of Benzene at 0.14 µg/L in the past three years. The statistics are as follows: 3-Year Average, ug/L 3-Year Max, ug/L # of Data Points Benzene Toluene Ethyl Benzene Xylene Naphthalene <1 <1 <1 <2 <1 0.14 <5 <5 <5 <5 36 36 36 36 36 Based on the effluent data from past three years, Motiva requests that monitoring frequency for BTEX and Naphthalene be reduced to annually. Removal of MTBE monitoring requirement Motiva has stopped using MTBE as oxygenate in gasoline since 2010, and monitoring results from the past three years have shown below the limits of detection for 27 out of 36 samples, with an average value of 0.65 µg/L for MTBE. Currently the Division's recommended criteria for MTBE is 19 µg/L, and Motiva's effluent does not show any reasonable potential to exceed the surface water criteria. In addition, Motiva Enterprises LLC 410 Tom Sadler Road Charlotte, NC 28214 MOTIVA ENTERPRISES LLC Motiva has been actively monitoring MTBE in the groundwater wells and is not planning to use MTBE for future production and operation. Therefore, Motiva respectfully requests the monitoring requirement for MTBE be removed from the permit. Reduce monitoring frequency for Acute Toxicity Testing to Annually Motiva has passed all quarterly WET tests as required by the last permit renewal with no demonstration of toxicity. In accordance with the Division's 2005 Permitting Strategy for Petroleum Bulk -Storage, Motiva respectfully requests that monitoring frequency for Acute Toxicity Testing be reduced to annually. Thank you for your assistance in processing this renewal application.
