Old Dawn, Maine 04468Masi ,.n Dear Jack: 4`4'"`"� This letter is written in response to inquiries concerning disposal of residue coal tar from the prior coal gasification plant in the _ city of Bangor. This coal 'tar exists in an open tank with an in- " definite, immiscible water layer., Latest estimates of quantities within this tank made by Diamond International indicate that this tank includes approximately 285,000 gallons of coal tar and approx- imately 70,000 gallons of water, with some additional water dissolved within the coal tar layer. ".n ux.umn Analysis of the coal tar layer shows percentage quantities of aromatics, phendics, and polynuclear aromatics, all substances that are designated - as hazardous by the HMTA, FWPCA, and under proposed RCRA. In that these _ substances are soluble to some limited degree, in water the water also presents a lesser disposal problem if not handled properly. To the city of Bangor these substances are a disposal problem. The Hazardous Waste = Management Group has been working with the city of Bangor to try to clean up these hazardous wastes. In dealing with hazardous wastes the D.E.P.'s firstinteresthas been to encourage recovery. With some reservations, Diamond International's interest in burning the coal tar _ -_ as a fuel appears to act beneficially for all parties concerned. Because the burning of coal tar with your Bark Burner may effect air pollution emissions, this problem willbe dealt with first. Analyses of the coal tar indicate 2.75% sulfur, 19% carbon, 6.3% oxygen and ' nitrogen, 14.6% water, 6.6% hydrogen, with trace heavy metal levels (lead at 1.8 ppm), and only trace chloride (indicating little, if any, chlorinated hydrocarbons). The enclosed letter in Appendix I qualifies the Air Bureau's concerns for burning of this coal tar and grants its approval. alliBn A " Diamond International Page 2 October 2, 1979 _ The contaminated water does not lend itself to recovery and must, therefore, be properly disposed of. An analysis of this water reveals.- . approximately 50. ppm of benzene soluble polycyclic aromatics. Such concentrations undiluted would be toxic to the aquatic environment. {, Also, this water should not be chlorinated, asthechlorinated by- products are orders of magnitude more toxic. Given a typical 20 % 106 gal./day flow at Diamond International______ Treatment Plant and a 10 - 20 x 103 gal./day bleed of the contaminated water should sufficiently dilute the contaminates to a non-toxic con- centration. In fact, the normal 2 day residence time within the treatment plant should offer ample opportunity for biological refractory of the polycyclic aromatics to simpler less toxic molecules. The final river dilution of approximately 1/1000 should render the level of the remaining contaminants to trace sub part-per-trillion levels. Because of, the importance in maintaining a sufficient control of the treatment .system within Diamond International, and because of the slight uncertanti es in dealing with polycyclic aromatics, a substantial test bleed of the con- taminated water should first be made with subsequent monitoring of the gross criteria, BOD.and Suspended Solids over this first period. This should eliminate anydoubtsconcerning adverse effects upon the micro- organisms within the secondary treatment system. The specifics to which this contaminated water disposal may. be carried out are outlined - in the enclosed letter in Appendix 1I. In many respects the coal tar may be treated as a bunker C oil. In the event of a catastrophic spillage while in transit the following counter measures should be followed. All possible liquid waste should be picked up by a vacuum truck. Absorbants should be added to the spilled area as soon as possible. This absorbent and all contaminated soils should then be trucked to a suitable landfill area. Continued inhalation of the vapors is not recommended, however, normal atmospheric conditions should suffi- ciently dilute the vapors to satisfactory air concentrations. Our Department will aid in whatever ways possible to facilitate any clean-ups or solving other environmental problems occurring as a result of this recovery operation. Needless to say, the transportation should be con- tracted to a reliable firm in order to minimize any risk of this kind. The Division of Oil Conveyance has been informed of this transportation and they and myself will be on call should clean-up consulting be required at that time. There should be no other environmental regulations that need to be addressed at this time. I see no further complications with residues in the air, water, or solid wastes (ash debris) that have not been presently discussed. Diamond International Page 3 October 2, 1979 Indeed this resource energy recovery from a potentially hazardous waste earmarks the sort of enterprising cooperation that should. . make a success for future hazardous waste management within the State of Maine.

The 1/1000 fold dilution '• data the plant should reduce the toxicity of this water to a point va - where further biological degradation may occur. The ensuing 1/1000 dilution into the Penobscot River should likewise remove this Fvkmau effluent from any violationsand eliminate the need for any toxicity monitoring. " i mum.uw Because of the unusual nature of this Contaminated water, I would prefer to secontinuous monitoring test following a controlled introduction of this water into the treatment system. Preferably, um'mu'w two 10,000 gallon increments of this contaminated water would be N bled into the system ov the first day. Assuming a two day residence time within the treatment system, BODS and Suspended Solids would be amonitored over this two day and two additional days. This would .r, take nine days to complete. No noticeable effects on the water c treatment System should be noticed. If during this period the ROD i° approaches 9800 lb/day or the Suspended Solids approaches 12,000 .a.% 16/day or if these parameters substantially deviate from average operation, the bleed rate of the contaminated water must be reduced accordingly. If no effects are noticed, then two 10,000 gallon increments may be bled into the treatment system on the tenth day. One 10,000 gallon increment may be bled into the system on the eleventh day, and two 10,000 gallon increments added on the twelfth day, alternating from this paint on. During this whole period BOO and Suspended Solids must be monitored and in the event of any sharp deviations or license violations, the increments must be re— duced. Should you have any questions or concerns, please feel free to notify me at any time• I appreciate your cooperation in dealing with this EXNIRIT C Dianna International - Page 2 Oetcher 2, 1979 - unique and difficult waste problem.

Please forward results of all testing during this paried to me, wean they become available.
