One Williams Center MD 27 Tulsa, OK 74172 Dear Ms. Little: Donald R. van der Vaart Secretary August 19, 2015 Subject: Change-Page(s) to Correct Error NPDES Permit NCO074705 Magellan Terminals Holdings, L.P. Charlotte I Terminal 7145 Old Mount Holly Rd, Charlotte 28214 Mecklenburg County The Division of Water Resources (the Division) staff noted a type-o for a parameter code in your recently issued permit (July 27, 2015). Total Suspended Solids (TSS) should have the parameter code C0530. Accordingly, we hereby forward the modified permit pages to amend Section A.(1.) of your permit with the following: Total Suspended Solids parameter code is C0530. In addition, parameter units were added to the table for your reference. Please insert these change pages into your existing permit and discard the old pages. We regret any inconvenience this causes your organization. Please note that this permit is not transferable except after notice to the Division. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Resources or any other Federal, State, or Local governmental permits that may be required. If you have questions, or if we can be of further service, please contact Derek Denard at [derek.denard@ncdenr.gov] or call (919) 807-6307. espe lly� Jay Zimmerman, D' or Division of Water Resources, NCDENR Enclosure: NPDES Permit NCO074705 (Corrected Pages) he: Central Files NPDES Program Files MRO Files/ Attn: Michael Parker ec: Richard Farmer [Richard.farmer@mecklenburgcountync.gov] Aquatic Toxicology Unit/ Susan Meadows [susm.meadows@ncdenr.gov] Joshua McDorman, Magellan Terminals Holdings, L.P.

(1.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS [15A NCAC 02B .0400 et seq., 02B .0500 et seq.] During the period beginning on the effective date of the permit and lasting until expiration, the Permittee is authorized to discharge treated stormwater from Outfall 001. Such discharges shall be limited, monitored and reported' by the Permittee as specified below: EFFLUENT CHARACTER19TXCS [Parameter Codes [P ] .

No later than 270 days from the effective date of this permit, the permittee shall begin submitting discharge monitoring reports electronically using the Division's eDMR application system [see A. (4.)]. 2. Flow shall be monitored with each discharge event — During periods of no flow, the Permittee shall submit a signed, monthly Discharge Monitoring Report (DMR) indicating "No discharge." Flow may be monitored using any one of four methods: a) measure flow continuously (via flow meter, totalizer preferred); b) calculate flow (see Rational Equation ) based on total rainfall per unit area draining to the outfall [see A. (3.)]; c) estimate flow at 20-minute intervals during the entire discharge event; or d) report flow based on discharge pump logs. 3. Turbidity — Effluent shall not cause receiving stream turbidity to exceed 50 NTU. If receiving - stream background exceeds 50 NTU, the effluent shall not increase background levels. Non- compliance with this Standard may require additional stream monitoring and a Turbidity Corrective Action Plan (TCAP). 4. This sample to be collected concurrently with Acute Toxicity. 5. Acute Toxicity (Fathead Minnow, 24-hour), Annual [see Section A. (2.)]. Conditions: The Permittee shall discharge no floating solids or foam visible in other than trace amounts. The Permittee shall discharge no tank solids, tank bottom water, or tank rag layer. Following hydrostatic tank or pipe testing, the Permittee shall discharge no wastes containing benzene concentrations greater than 74.1 µg/L, or toluene concentrations greater than 11 µg/L. Page 3 of 7 Permit NCO074705 A. (2.) ACUTE TOXICITY MONITORING (ANNUAL) [I5A.NCAC 02B .0500 et seq.] The permittee shall conduct acute toxicity tests on an annual basis using protocols defined as definitive in EPA Document EPA-821-R-02-012 entitled "Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters 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 during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all waste treatment processes. The parameter code for Pimephales promelas 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, DWR Form AT-1 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1623 Mail Service Center Raleigh, North Carolina 27699-1623 Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section 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 Resources 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.
