Ross, Jr., Secretary —1 North Carolina Department of Environment and Natural Resources Gregory J. Thorpe, Ph.D., Acting Director i;s Division of Water Duality November 16, 2001 Brenda Meador Apex Oil Company 2801 Rock Road Granite City, Illinois 62040 Subject: FINAL -- NPDES Permit No. NCO071463 Apex Oil Company, Greensboro Terminal 6900 West Market Street Guilford County Dear Ms. Meador: This letter transmits your final NPDES individual discharge permit for the subject facility. Please review this final document carefully to ensure thorough understanding of the information, conditions, and requirements of dischargers to water supply (WS) waters contained therein. The Division of Water Quality (the Division) has revised permitting strategies and Standard Operating Procedures (SOP) for this and all bulk storage petroleum facilities and terminals in North Carolina. As part of permit renewal, the Division has also conducted EPA -required Reasonable Potential Analysis (RPA) on this facility's effluent data to determine the "reasonable potential" for identified parameters to exceed North Carolina receiving -stream Water Quality Standards and criteria. The following explanations summarize current changes to your previous permit in compliance with the new 2001 SOP. BTEX. Apex Oil Company (Apex) is now required to monitor monthly for BTEX (benzene, toluene, ethyl benzene and xylene) parameters. Please note that this requirement replaces EPA Method 624. These renewal parameters are not permit -limited currently because the RPA indicates no "reasonable potential," based on data submitted. For example, benzene's RPA "maximum predicted" effluent level of 0.05 µg/L (based on submitted data) does not exceed its 1.19 µg/L "allowable concentration." Data suggest that there is no "reasonable potential" to exceed receiving -stream Water Quality Standards. EPA Methods 624/625. Method 624 has been eliminated from facility monitoring if it did not detect compounds other than BTEX. However, because the majority of facilities now store, or have stored in the past, heavy -component fuels such as fuel oil and diesel, the Division has retained EPA Method 625 monitoring to detect naphthalene and related indicators of middle distillate compounds commonly found in these heavier fuels. The Division will consider a request to discontinue this monitoring if the Permittee can document that the subject facility does not now, nor has ever, stored heavier -component fuels. &A NCDENR N. C. Division of Water Quality 1617 Mail Service Center Raleigh, NC 27699-1617 919-733-7015 Customer Service 1-800-623-7748 Apex Oil Company Greensboro Terminal NPDES Permit NCO071463 Page 2 Phenol. The Division recalculated a phenol stream-wasteload allocation of 0.002 lbs./day at the USGS stream gauge (0209400000) on Horsepen Creek — the assumed beginning of Lake Brandt Water Supply. This allocation was distributed equally between two (2) bulk -storage facilities within this drainage (0.001 lbs./day per discharger). These calculations are available upon request. Apex did not detect phenol at a test -method practical quantitation level (PQL) of 5.0 µg/L in 37 sample events. Therefore, there is no "reasonable potential" and a phenol limit has not been included in the permit. Please continue to insist on, and report, the lowest PQL possible from your North Carolina —certified laboratory. MTBE is a gasoline component recently identified by the EPA as a potential human carcinogen. Therefore, monthly monitoring has been added to this and all oil terminal permits discharging to WS waters within the state. After collecting additional data, the permittee may request the Division to reduce the MTBE monitoring frequency (See Special Condition A. 2.). Granting this request shall constitute a minor modification to the NPDES permit. Concerning Total Suspended Solids (TSS). During 24 of 25 discharge months (January 1999 through June 2001) Apex reported TSS levels in excess of the permit Daily Maximum of 45.0 mg/L. Annual discharge averages include 79.5 mg/L (1999), 67.1 mg/L (2000), and 63.5 mg/L (2001). A high value of 272 mg/L — six times the permit limit — was reported in June 2000. Apex shall therefore design and implement a TSS Prevention and Recovery Plan, thereby employing all means necessary to comply with the permit limit. Although TSS was discussed, this requirement was not specified in the draft permit. This facility's discharge of TSS will be further evaluated during the coming permit cycle. Lead was limited in the previous permit and will also be limited in the new permit. The RPA "maximum predicted" effluent level of 140.0 µg/L (based on submitted data) exceeds the allowable concentration of 25.0 µg/L. This indicates "reasonable potential" to exceed the instream Water Quality Standard for lead. Oil & Grease. Similar to lead, oil and grease were also limited in the previous permit. This limit will continue because the RPA "maximum predicted" effluent level of 51.6 µg/L exceeds the allowable concentration of 30.0 µg/L, based on data submitted by the permittee. If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable, you have the right to an adjudicatory hearing upon written request within thirty (30) days after receiving this letter. Your request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is made, this permit shall be final and binding. This permit is not transferable except after notifying the Division of Water Quality. The Division may require modification, or revocation and re -issuance of this permit.

The permittee shall not discharge tank (or pipe) contents following hydrostatic testing unless benzene concentration is less than 1.19 µg/L and toluene concentration is less than 11 µg/L. Permit NCO071463 EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A. (2.) MTBE MONITORING For the protection of public health, oil terminals discharging to waters classified as water supplies ("WS" waters) shall adhere to the following action plan: 1. Monthly monitoring for MTBE (except as modified under 2.) is required for the duration of the permit [See Part A. (1.)]. 2. After a one-year Test Period of monthly monitoring or after twelve (12) discharge events have .been sampled and analyzed, the Permittee shall review MTBE data. If MTBE is not detected, the facility may request the Division to reduce the MTBE monitoring frequency. Granting this request shall constitute a minor modification to the NPDES permit. 3. If MTBE is detected during the Test Period, the Permittee shall submit an MTBE Reduction Plan. This plan may include site -specific Best Management Practices (BMPs) or engineering solutions. A copy of this plan shall be submitted to: North Carolina Division of Water Quality Water Quality Section Attn: NPDES Unit 1617 Mail Service Center Raleigh, NC 27699-1617 4. The Division anticipates that an MTBE regulatory criterion or Water Quality Standard will be established during the coming permit cycle. For the next cycle of permit renewals, the Division expects to apply this criterion or standard to MTBE data collected during this permit cycle. Should the permittee's MTBE data indicate discharge in excess of this criterion or Water Quality Standard, an MTBE limit will be added to the permit monitoring requirements at renewal. Permit NCO071463 EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A. (3.) ACUTE TOXICITY MONITORING (ANNUAL) The Permittee shall conduct annual toxicity tests using protocols defined as definitive in EPA Document EPA/600/4-90/027 entitled "Methods for Measuring the Acute Toxicity of Effluents to Freshwater and Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24-hour static test. Effluent samples for self -monitoring purposes must be obtained below all waste treatment. The permittee will conduct one test annually, with the annual period beginning in January of the calendar year of the effective date of the permit. The annual test requirement must be performed and reported by June 30. If no discharge occurs by June 30, notification will be made to the Division by this date. Toxicity testing will be performed on the next discharge event for the annual test requirement. The parameter code for this test is TAE6C. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it was performed, using the appropriate parameter code. Additionally, DWQ Form AT-1 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quality Environmental Sciences Branch 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should any test data from either these monitoring requirements or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re- opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

The Permittee's 5-year NPDES permit has expired and they have requested renewal from the Division of Water Quality (the Division). This Fact Sheet summarizes background information and rationale used by the Division's NPDES Unit to determine permit limits and conditions. This document also contains references to information sources relevant to this permit renewal (superscripted numbers in order of appearance, See References). FACILITY RECORDS REVIEW Facility Description. Apex (Table 1) operates the Apex Oil Company, Greensboro Terminal, a bulk storage petroleum fuel distribution center in Guilford County. Discharge from the facility consists of stormwater runoff controlled by a Water Pollution Control System consisting of: loading rack drains; oil/water separator; waste holding tank with optional offsite disposal; pumps to empty dike containment areas trough the oil -water separator; and discharge control valves. Discharge travels to an unnamed tributary (UT) of Horsepen Creek. Table 1.

To stager the renewal workload, the Division extended the expiration date to expire June 30, 2001.1'2 Waste Load Allocation (WLA). The Division conducted a WLA in March 1994 and developed effluent limits and monitoring requirements based on an in -stream waste concentration (IWC) of 100% (zero -flow stream).6 The Division judges these limits and monitoring requirements to be appropriate for this renewal with the exception of additions and deletions listed below (see PERMITTING APPROACH SUMMARY). Verifying Existing Stream Conditions. This facility discharges to a "zero -flow" stream, an unnamed tributary (UT) Horsepen Creek, a Class WS-III NSW stream within the Cape Fear River Basin. Horsepen Creek is not listed as an "impaired" waterbody [not 303(d) listed].s COMPLIANCE REVIEW Discharge Monitoring Reports (DMR) -- Effluent Data Review. DMRs were reviewed from January 1999 through June 2001.E Discharges from Outfall 001 occurred episodically, zero to four times per month — non -discharge months reported as "no flow." The permittee reported a maximum discharge of 0.0.096 MGD (June 2000). Therefore, this flow was used for reasonable potential calculations (see below). Monitoring parameter results are summarized in Table 2: Table 2.

Fact Shcet Renew,d -- N PDES NCO07 ! 463 Page 2 Based on the Division's our review of the DMRs, twice annual EPA 624/625 scans did not detect semi -volatile or volatile organic compounds. Total suspended residue (TSR) results do not exceed recommended levels. Notices of Violation (NOVs). No NOVs were issued to this facility during this permit cycle.8 Facility Inspections. This facility was last inspected September 1995 in connecting to an Authorization To Construct (ATC) an oil —water separator. Beginning with this permit cycle, the Winston-Salem Regional Office has scheduled regular annual inspections for this and all bulk - petroleum storage facilities in the Greensboro area.9 Whole Effluent Toxicity (WET) Test. The facility has passed its annual acute toxicity test for four (4) years, from 1998 through year 2001. Total Suspended Solids (TSS). During 24 of 25 discharge months (January 1999 through June 2001) TSS levels are reported in excess of the permit Daily Maximum of 45.0 mg/L Annual averages are 79.5 mg/L (1999), 67.1 mg/L (2000), and 63.5 mg/L (2001). A maximum was reported in June 2000 of 272 mg/L. These violations have not been assessed. According to the Compliance and Enforcement Unit, future discharges in excess of 45.0 mg/L will be assessed as a violation-9 A note to this effect will be added to the permit cover letter. PERMITTING STRATEGY Revised Standard Operating Procedures (SOP). The Division has revised permitting strategies and SOP for this and all oil terminals in the state based on a 1996 SOP. This document, hereafter referred to as the 2001 SOP,10 addresses issues and delineates monitoring frequencies and permit limits for contaminants commonly found at these facilities. Summary of Compliance Under 2001 SOP. Under the 2001 SOP, flow monitoring will be changed from "monthly" to "episodic" (Parts L.A. ). Compliance for acute toxicity, TSS, and oil and grease (Parts L.B. through I.D.). In place of EPA Methods 624/625 monitoring requirements [eight (8) chlorophenols specified in the previous permit], the permittee shall now monitor monthly for phenol only (Part LE.), required for all WS (water supply) waters, and for BTEX (Part III.A.). The Division shall also require monthly monitoring for MTBE (2001 SOP Part I.I.) considering WS waters. 10 Footnotes to the Effluent Limits and Monitoring Requirements page shall reflect no direct discharge of tanks solids, tank bottom water, or the tank rag layer. Footnotes also stipulate no direct discharge of hydrostatic test water if benzene and/or toluene concentrations exceed their respective water quality standard (2001 SOP, Parts I.G. and I.I). Phenol — Monitoring and Limits Calculations. When combined with chlorine, phenol can cause taste and odor (organoleptic) problems in drinking water, and can also result in the tainting of fish tissues. Therefore, in accordance with SOP 2001, all dischargers to state water supply (WS) waters shall conduct monthly effluent monitoring for total phenol.10 Moreover, if analytical results suggest "reasonable potential," a phenol limit shall be included in the permit.7 A phenol limit magnitude depends on dilution. Ideally dilution would be calculated at the Lake Townsand Dam water plant intake where chlorine is introduced, but it is impractical at this time to Fact Sheet Renewal -- NPDE.S NCO071463 Page assumed headwaters of this water supply. Secondly, the Division used 1 µg/L (the aesthetic limit for phenol) to calculate a wasteload allocation in pounds per day (lbs./day) at these headwaters. Finally, the wasteload allocation was distributed equally among phenol dischargers as a permit limit, but only as each facility's data -set showed reasonable potential to exceed the water quality stream standard. Currently two (2) bulk storage facilities discharge to Horsepen Creek draining to Lake Townsand, the nearest downstream intake waterbody. An EPA stream gauge (0209400000) located on Horsepen Creek was assumed for the following calculations to approximate the headwaters of Lake Townsand. The Division used published 30Q2 flows from this stream gauge to calculate a wasteload allocation for phenol. The 30Q2 flow, not the 7Q 10, was deemed appropriate because the standard for phenol is aesthetic. Flow Calculations: Given: Flow (30Q2) = 3.3 cfs (USGS Gauging Station) Drainage Area = 16.40 mil (USGS) Yield = Flow (cfs) Drainage Area (mil) = 3.3 cfs 16.40 mil 0.20 efs/mi2 Therefore: Total Flow = Yield x Total Drainage Area 0.20 cfs/mil x 16.40 mil 3.3 cfs Wasteload Calculation: 3.3 cfs x 0.001 mg/L x 8.34 = 0.002 lbs./day distributed among two (2) 1.55 dischargers 0.002 lbs./day 2 dischargers 0.001 lbsJday per discharger Phenol Limit: Maximum reported flow = 0.096 MGD Limit = Allocated wasteload (lbs./day) x 1.0 mW_ 8.34 lbs./MG Highest Reported Flow (MGD) = 0.001 x 1.0 8.34 0.096 .00125 mg/L 1.25 µg/L Fact Sheet Renewal -- NPDES NCO071463 Payc 4 QUESTION: Using 0.001 lbs. per day as the wasteload allocation for phenol, does the allowable concentration (calculated limit) exceed the maximum predicted concentration for this facility? Max Predicted: Allowable: ANSWER: YES. 16.7 µg/L (no hits in 37 @ 5 µg/L) 1.25 µg/L However, a phenol limit will not be included in this permit because: 1. phenol was not detected in 37 samples at 5 µg/L, and 2. because the "maximum predicted" is based solely on'/z the test -method Practical Quantitation Limit (PQL), and 3. because an analytical method more sensitive than 5 µg/L is not currently available. Summary of Reasonable Potential Analysis (RPA). The Division conducted an EPA -mandated RPA on Apex's reported data for benzene, phenols, oil & grease, and lead. There were insufficient data to establish reasonable potential for ethyl benzene, toluene, and xylene. Maximum Predicted Allowable Reasonable Potential Benzene 0.5 µg/L 1.19 µg/L No Phenol 16.7 µg/L* 1.25 µg/L Yes* Oil and Grease 51.6 µg/L 30.0 µg/L Yes Lead 140.6 µg/L 25.0 µg/L Yes * based only on 1/2 PQL of 2.5 µg/L; no hits @ 5.0 µg/L (see phenol calculations) Therefore, the allowable concentrations for lead and oil & grease will be included as limits in the permit, per the 2001 SOP. Phenol will be monitored per SOP 2001, but no permit limit will be imposed. Permitting Approach Summary Per DWQ/NPDES Unit's 2001 SOP: • Incorporated BTEX monitoring, frequency Monthly per SOP 2001. • Benzene remains in the permit; no added limit due to no "reasonable potential" • Removed EPA Method 624 monitoring; "no parameters detected." • Method EPA 625 monitoring remains at 2/Year per SOP 2001. • Phenol remains in permit -- no change in Monthly monitoring frequency; no permit limit because not detected (despite "reasonable potential"). • Per requirement for WS waters, added Monthly MTBE monitoring, no limit. • Oil and Grease — monitor Monthly; previously limited/currently limited; "reasonable potential" — yes. • Lead — RPA indicates "reasonable potential;" monitor Monthly with limit.
