Permit NC0005771 A. (1.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS Beginning on the effective date of the permit and lasting until expiration, the Permittee is authorized to discharge from Outfall 001. Such discharges shall be limited and monitored by the Permittee as specified below: EFFLUENT, " ._ MI LITS l ,;„ �'' -MONITORING,'_ REQUIREMENTS` :'. �-IN bA 4 CHARACTERISTICS> �� Monthlyt � Daily c' '_Measurement " Sample° 'SampleLocation'' , : s_.. . :tx". ,.._ Avera e. x Maximum.- Fre uenc Flowl i Episodic 1 Effluent Total Suspended Solids 45.0 m Monthly Grab Effluent Oil and Greasez Monthly Grab Effluent Turbidity' Quarterly Grab Effluent Benzene Quarterly Grab Effluent Toluene Quarterly Grab Effluent Ethyl Benzene Quarterly Grab Effluent X lene Quarterly Grab Effluent Naphthalene 4 Monthly Grab Effluent Acute Toxicit 5 Annually Grab Effluent Footnotes: 1. Flow — During periods of no flow, the Permittee shall submit a monthly Discharge Monitoring Report (DMR) indicating "No discharge." Flow should be monitored with each discharge event in one of four ways: a) measure flow continuously; b) calculate flow based on total rainfall per area draining to the outfail; exclude built-upon area (See Special Condition A. (3.) for rational equation); c) estimate flow at 20-minute intervals during the entire discharge event; or d) report flow based on discharge pump togs. 2. Oil and Grease — Where possible, the grab sample for oil and grease should be skimmed from the surface of a quiescent (calm water) zone. 3. Turbidity—Effluent shall not cause receiving stream turbidity to exceed 50 NTU. If receiving stream background turbidity exceeds 50 NTU, effluent shall not cause this background value to increase. 4. Naphthalene — Monitoring requirement applies to facilities that store, or historically stored, diesel or other heavy fuels on site. 5. Acute Toxicity (Fathead Minnow, 24-hour), Annual [see Special Condition A.(2.)]. Permit holder shall sample for acute toxicity and BTEX concurrently. There shall be no discharge of floating solids or foam visible in other than trace amounts. There shall be no direct discharge of tank solids, tank bottom water, or the rag layer. There shall be no direct discharge of tank (or pipe) contents following hydrostatic testing unless benzene concentration is less than 71.4 µg/l and toluene concentration is less than 11 µg/l. Permit NC0005771 EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS . SPECIAL CONDITIONS A. (2.) ACUTE TOXICITY MONITORING (ANNUAL) The Perniittee 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. Permit NC0005771 A. (3.) RATIONAL EQUATION The Rational Equation: Q=KuCIA, where: Q = flow(peak flow rate (cfs or m3lsec) Ku = units conversation factor= 1.008 for U.S. standard units (usually ignored because it is so close to 1), or 0.278 for SI units C= dimensionless runoff coefficient for the watershed, loosely defined as the ratio of runoff to rainfall I= intensity of rainfall taken from the intensity-duration-frequency curves for the specified design return period at the time of concentration, tc (in/h or mm/h). tc= time of concentration (time after the beginning of rainfall excess when all portions of the drainage basin are contributing simultaneously to flow at the outlet). A= area of tributary watershed(acres or km2) The rational equation is used to calculate the runoff from a region, given: • the runoff coefficient which accounts for infiltration and other potential losses in the region, • the rainfall intensity to the region, + the time it takes for runoff to travel from the region's upper reaches to its outlet, and the region's drainage area.

We request removal of the Toluene limit. Analytical results from sampling events for the years 2001, 2002, 2004, and y-t-d 2005 have all been non-detect. During 2003, toluene was detected at 8.9 mg/i in March and at 8.0 mg/I in December. We appreciate your review of the DMR data submitted for the current permit term and approve our request for removal of the Toluene limit. We also request that monitoring for Benzene, Toluene, Ethylbenzene, and Xylene be changed to Quarterly monitoring as is written in the draft permit for our Charlotte#2 facility. Should you have any questions, please contact me. Thanks.

Effluent water discharged from the single outfall consists of runoff from the loading rack and stormwater from the secondary containment areas (around the individual tanks). Loading rack water is run through grit screens and an oil water separator. This water then flows into two retention ponds (where it combines with stormwater)and is released from the second retention pond manually as needed. FILE REVIEW Correspondence The Mecklenburg County Department of Environmental Protection (MCDEP) conducts annual inspections at this facility as part of a cooperative working agreement between the county and DWQ. Inspection records indicate satisfactory ratings in all inspected areas. The facility has not received any notices of violation in the past permit term. DMR Review: DMRs were reviewed from April 2003 through March 2005. Discharges are sporadic in nature; for those months in which flow was recorded, the mean flow was 0.194 MGD. The maximum flow (used below in the reasonable potential calculations) was 0.3 MGD. Total suspended solids during this time averaged 8.9 mg/L with a maximum of 22 mg/L. Monitoring for oil and grease showed all values less than the detection level of 5 mg/L. The permit requires monthly monitoring for BTEX and MTBE and quarterly monitoring for turbidity. These are addressed below in the RPA section. The twice-annual EPA 624/625 scan revealed non-detects for all additional parameters tested. The facility has passed all its annual acute toxicity tests since the 2001 permit renewal. Reasonable Potential Analysis: Reasonable Potential Analyses were considered for turbidity and BTEX. Turbidity showed no reasonable potential. All levels for Benzene, Xylene, Ethylbenzene were below detection level. All samples for benzene were less than a detection level of 5 µg/L. However, with a detection level so high and a standard Fact Sheet NPDES NCO005771 Renc-%vul Page l G Z--/�� �� -b wao>7 , on� Q� of I u L,-the data is not useful. Toluene {with e detection) slowed reasonable potential, with a predicted entration of 15.4 µg/L to the allowable of 1 I ttg/L. Xylene and ethylbenzene were not detected above the quantitation levels. PERMITTING STRATEGY The permitting strategy for this and all oil terminals in the state is based upon a document entitled, "NPDES Permitting Requirements for Discharges for Petroleum Bulk Storage, Surface Storage Greater than One Million Gallons, 2005-Permitting Strategy Addendum." This document is based upon a 2001 SOP and has been updated after a data review and internal discussions. It delineates monitoring frequencies and permitting limits for contaminants commonly found at these sites. Below, it is referred to as the "2005 Permitting Strategy." Oil Terminal SOP: Requirements specified in the previous permit remain unchanged except for toluene, which showed reasonable potential to exceed water quality standards and will be limited at I jig/L. As per parts I.G. and I.H. of the 2001 SOP, there can be no direct discharge of tanks solids, tank bottom water or the rag layer, and no direct discharge of hydrostatic test water if concentrations of benzene and/or toluene exceed the water quality standard. Part II.C. lists a requirement specific to the Paw Creek terminals —quarterly turbidity monitoring as mandated by the EPA. SUMMARY OF PROPOSED CHANGES • Addition of toluene limit • Remove requirement for Method 625 scans based upon 2005 permitting strategy. • Add monthly monitoring requirement for naphthalene based upon 2005 permitting strategy. • Remove MTBE monitoring based upon 2005 permitting strategy.
