Govemor D. E. Benton r Chief Deputy Secretary .� North Carolina Department of Environment and Natural Resources Coleen H. Sullins, Director Division of Water Quality April 15, 2008 Barbara Castleberry, Environmental Coordinator TransMontaigne Product Services, Inc. 2000 Mansell Court East, Suite 600 Roswell, Georgia 30076 Subject: Dear Ms. Castleberry: Modification of NPDES Permit NC0026247 TransMontaigne Southeast Terminal 6801 West Market Street, Greensboro Guilford County The Division of Water Quality (the Division) has received and reviewed your request to modify permit monitoring requirements for Methyl Tertiary Butyl Ether (MTBE) for the subject facility, in accord with your permit Special Condition A.(2.). We concur that your data comply with this Special Condition. Based on your 2007-2008 analytical dataset for MTBE, the Division hereby grants a reduction in monitoring frequency from Monthly to Quarterly for MTBE. Please add the attached permit change - pages to your existing permit and discard the old pages. EPA's ongoing research and evaluation of this toxicant as a potential human carcinogen raises our concerns about your facility's discharges to a waterbody classified as Water Supply (WS-IV). Therefore we feel your request to "discontinue monitoring" altogether is premature, and have modified your permit consistent with existing guidance for similar fuel bulk -storage facilities across the state. Please notice that this permit is not transferable except after notifying the Division of Water Quality. The Division may modify, or revoke and reissue this permit. This permit does not affect your legal requirements to obtain other permits from the Division of Water Quality, the Division of Land Resources, the Coastal Area Management Act, or other federal or local governments. If you have questions concerning this permit modification, please contact Joe Corporon at (919) 733-5083, extension 597 or email joe.corporon@ncmail.net. Sincerely, Coleen H.

Flow — During periods of no flow, the Permittee shall submit a monthly Discharge Monitoring Report (DMR) indicating "No discharge." Flow shall be monitored with each discharge event and may be monitored in one of four ways: a. measure flow continuously; b. calculate flow based on total rainfall per area draining to the outfall; exclude built - upon area (best method for facilities with large runoff -collection ponds); c. estimate flow at 20-minute intervals during the entire discharge event; or d. report flow based on discharge pump logs. 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. Acute Toxicity (Fathead Minnow, 24-hour), Annual [see Special Condition A.(3.)]. Units: mg/L = milligrams per liter µg/l = micrograms per liter MTBE = methyl tertiary butyl ether The Permittee shall not discharge floating solids or foam visible in other than trace amounts. The Permittee shall not discharge tank solids, tank bottom water, or the tank rag layer. The Permittee shall not discharge tank (or pipe) contents following hydrostatic testing unless benzene concentration is less than 1.19 pg/L and toluene concentration is less than 11 pg/L. Ira INC.
