The present treatment consists of two () oil/water separators that have the same discharge outlet. The existing loading racy is in the process of being replaced by a new loading rack, however, the oil/water separation system will remain the same. The new loading rack will have new lines and tie into the oil/water separator. A review of the monitoring reports from 11/88 to 10/89 did not reveal any problems. There did not appear to be any problems with the treatment of the wastewater or the treatment process. It is recommended that the NP%ES Permit be issued. a Signature of Report Peparr Water Quality Regional Supervisor ""u�./r 'tt°.. �^�� � � ��/ �"`�^s'" ``� �,,;�,r?�� '/ '✓'``� � �+i� � ."tr r�- � v, t w ` * mpppppp— XV c` *�. � �`a }yttr�f��k. . , �"i"' 3 4 yrQ1r' C� • Gra 114�*' W.

If continuous flow monitoring is no f sible, record the approximate time that discharge began and ended, along with the instantaneous flow at the time of the effluent sampling. ***The discharge shall not cause the turbidity of the receiving water to exceed 50 NTU. If the turbidity exceeds these levels due to natural background conditions. the discharge level cannot cause any increase in the turbidity in the receiving water. ****Chronic Toxicity (Ceriodaphnia) P/F at 90%; January, April, July, October, See Part III, Condition E. *****BTEX parameters should be monitored using an EPA approved method to a detection level of I pp b (99A). The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units and shall be monitored monthly at the effluent by grab sample. There shall be no discharge of floating solids or visible foam in other than trace amounts. Minimum treatment for the groundwater rem ediation will include oil/water separator, air stripping or used aeration and Activated Carbon Adsorption. Treatment for the stormwater will include an oil/water separator. Design and Construction of the Waste Treatment Facility will emphasize the use of plastic pipes and fittings where practically possible. pppppp� Part III t ,. Permit No. NCO004839 D. Disposal Alternatives The Pemittee shall continually evaluate all wastewater disposal alternatives and pursue the most environmentally sound alternative of the reasonably coast effective alternatives. If the facility is in substantial non-compliance with the terms and conditions of the NPDES permit or ,governing rules, regulations, or laws, the permittee shall submit a report in such form d detail as required by the Division evaluating these alternatives and a plan of action withinsixty (60) days of notification by the Division E. CHRONIC TOXIC PASS/FAIL PERMIT LIMIT QR Y ) e effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in; 1.) The North Carolina Ceriodaphnia chronic effluent bioassay 'procedure (North Carolina Chronic Bioassay Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant t mortality is 90% (defined as treatment two in the North Carolina: procedure document). e permit holder shall perform quarterly monitoring using this procedure to establish compliance with the permit condition, The first test will be performed after thirty days from the effective elate of this permit during the months of January, April, duly and October. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered: can the Effluent Discharge Monitor' Form (MR-1) for the month in which it was performed, using the parameter code TGP3Bm Additionally, DEM Form AT-1 (original) is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy e Road Raleigh, N.C. 27607 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 single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin immediately until such time that a single test is passed.. Upon passing, this monthly test requirement will revert to quarterly in the months specified above. Should any, test data from this monitoring requirement or tests performed by the North Carolina Division of Environmental Management indicate potential impacts to the receiving stream, this permit may 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 d will require immediate retesting(within 30 days of initial monitoring event).

This request was made as a result of recent developments arising from the encounter of free phase gasoline on the watertable at the Charlotte Terminal. Background of this situation was provided to you by both Exxon and Mr. ,Robert Owens, EA Engineering, our environmental consultant. The free phase gasoline has recently appeared in downgradient observations wells, which were previously clean. This indication of gasoline movement requires prompt action to prevent further movement offsite.- We have ;proposed a total fluids drawdown in this area including treatment of the recovered g g p sting NPDES permit. groundwater to meet the discharge e ammeters f our existing �µ. ^ We will provide your office with updates on the details of the recovery system and volumes/rates of water discharged.

The same water will be used to test all three tanks: After the hydrostatic tank tests are completed the water will be sampled and analyzed, including BTEX, for contaminant constituent levels prig to discharge. If the tests conclude EP and TC constituents are below regulatory levels Exxon Intends to discharge this water through the existing NPDE outfall at this facility: However, should testing indicate any constituent contamination levels greater than allowable limits, Exxon will not discharge the water until the water has been treated to a level mere further testing i conducted and indicates compliance with these limits. Exxon has recently conducted hydrostatic tank test's at the Greensboro terminal facility. Toxicity tests of the the water remaining after the hydrostatic tank tests were completed all were within regulatory parameters.

Our experience from treating tank water bottoms for oil companies in die past is that tank water bottoms have the following characteristics: Petroleum Hydrocarbons 50-250 ppm Benzene 10-200 ppm Toluene 10-200 ppm Ethyl Benzene 10-200 ppm Xylenes 10-200 ppm pH 5-10 COD 500-3,000 TSS 2- 20 ppin We propose to meet die following effluent criteria: Total Benzene, Toluene, Ethyl Benzene and Xylenes (BTEX) I ppm Total Petroleum hydrocarbons 5 ppm pH 5-10 TSS 2 mg/L During the final pass, the pumped water from the 22,000 gallon tank will initially enter a holding tank prior to sand filtration (2 units, I operational; is are backwashable) for silt removal and/or removal of particulate metals. Following particulate removal, the water enters an air stripping tower followed by liquid phase granular activated carbon treatment. The gaseous emissions from the air stripping tower are treated by steam regencrable gas phase activated carbon. The regenerated gas carbon produces free phase product which is given back to the client as recycled product (in drums). The trailer is equipped with two liquid phase carbon vessels (one operating and one on stand-by) and two gas phase carbon beds (one operating and one steam regenerating, steam boiler on the trailer). The final effluent can be recycled to the head of the treatment trailer for additional PPV aired. mobile trailer;is equipped with 2 flame ionization detectors to monitor lity as well as air quality ftom the gas phase activated carbon units. scharging the effluent over a 1-2 day period in April 1991.

Each batch of water was initially'recycled through the air stripper and multi -media filters d subsequently pumped back to the frac tank. This initial recycling loop allowed maximum adsorption and subsequent desorption of the dissolved gasoline constituents onto the refine able gas phase carbon (maximum collectable reclaimed product) and also ensured that upon further treatment (second pass) through Cle °s system, the discharged effluent would meet discharge criteria. The water was recycled (through filters and air stripper) back to the frac tank for ` a period of approximately 6 hours at a flow rate of approximately 60 gprrL Upon recycling for 6 hours, the water ftom the frac tank subsequently undergoes full treatment from the mobile system. The water initially entered a holding tank prior to multi -media filtration for particulate removal'. Following filtration, the water entered the air striping tower followed by liquid phase granular activated carbon treatment . The two CAC liquid phase units (1,500 lbs each) were used in series , Emissions from the air stripper were treated by gas phase steam eg erable activated carbon. The recycled product collected from steam regeneration (12 gallons; 6" thickness in a 55 gallon m) was collected and stored in a labelled DOT approved drum and left for the client The gas phase carbon vessels did not show breakthrough during monitoring. The system operated during the recycling operations without problems. The system water and air effluent were of high quality and met all permit requirements. 3.0 »ANALYTICAL METHODS & RESULTS 3.1 Methods Analysis was performed with a Shimadzu Gas Chromatograph (GC) model A. The GC is equipped with two flame ionization detectors (FID) and two 10 meter packed columns. GC output is stored and quantified by a Shimadzu Integrator. The GC injector and detector temperatures were set at 170 C. The column temperature increased from 70 C to 120 C at a to of 8 degrees per minute. Gas flow to was set at 3.25 Kpa. pumping. Air Stripper effluent, and the effluent of the first GAC column were also periodically sampled. Water samples were analyzed using the following field headspace analytical method: I- The s=pies were placed in 40 ml VOA vials. 2- 10 ml were withdrawn from the vials. 3- The vials were placed in a constant temperature bath (70C) and allowed to equi�brate- 4- Prior to analysis, the heated samples were shaken vigorously for 20 seconds. 5- 500 microliter (uL) of vial headspace gas were injected into the GC. 6- Duplicate samples (2 separate VOA vials) were used for all analyses. Syringe blanks as well as 100 ppb, 1,000 ppb and 10,000 ppb standards of BTEX were used to calibrate the instrument before Dumping. Ait S Analysis Air Samples were withdrawnfrom the treated effluent stream (after gas GAC treatment) every four hours. Samples were withdrawnusing a 500 ul, syringe directly from a septum sealed sampling port in the effluents k" The syringe volume was subsequently directly injected into the GC at the previously mentioned chromatographic conditions. 3.2 Results Benzene, Toluene, Ethyl Benzene and Xylenes in the samples were quantified according to the CC response to that particular compound's response factor (area countfng injected) for the standards (100, 1,000, and 10,0001ppb BTEX standards). The total VOC numbers represent all compounds including, BTEX, present in the sample. In general the analytical methods showed excellent reproducibility for duplicate comparison. cknaal nos, Appendix A contains summary tables of the analytical results. In general the water effluent showed Benzene concentrations ranging from non detectable to 29 ppb, well within permit reouirements (40 unb). Influent VOC concentrations ranzed from an'Droximatelv 68 to 161 D-Drn d Benzene levels were measured at approximately 17- ppnL e discharged air stripper emissions showed consistently low levels of VOCs. Appendix B shows sample GC: outputs the water influent, water effluent and air effluent. 4.0 SUMMARY The following summary points can be e; • All permit requirements for liquid and gaseous effluent were met. 12 gallons of dissolved gasoline product were recovered Table 1 .
