"0: k.h. Conrad FROM: R.D. Hillman. S.V. Corkran, and G.G. Bacon (PED) DATE: May 22, 1937 SUBJECT: Heavy Ends Disposition White Paper Attached are the results of the study made to examine the proposed options for the disposition of the heavy ends material produced at the VCM f:'.l ant as a by-product, in the manufacture of EDC and VCM. Several options were examined with the majority of the time spent examining options which involved sending the heavy-ends to PPG, as is currently done, sending the heavy ends to BFG in La Porte, and the use of the VCM Plant incinerators to burn the heavy ends. The results of this study indicate that the most desirable solution to the heavy ends disposition problem would involve continuing to send aoout one-half of the material to PPG and to negotiate a contract with B.F. Goodrich in La Porte in which BFG would agree to take the remaining material for use as feedstock for their CATOXID Unit. This solution (with an NPV of $:92"93M relative to the current practice) , would be more economical than both the current practice of sending the heavy ends to PPG or permitting and revising the VCM Plant incinerators to burn the heavy ends (with an NPV of -:17i-3B0M relative to the current practice). This option would provide Vista wi_th t.wo_d i sposl't i on options white not having a possible affect on. the stream factors of the VCM Plant or itsi incinerators!. There would be no increase in the risk\of possiblyiincreased regulation or enforcement measures ^applied to f.he incinerators which could result if Ahe number .of incinerator bypasses' and st^ack v" excedancesj which could be increased by-.burning__heavy ends, increases sufficiently to draw action by regulatory actions. A decision must be made to determine which of the options discussed in the attached document should be made as soon as is practicable due to the existing deadlines which would apply to the permitting process of the incinerators. A complete permit application should be submitted by August S, 1997 to ensure that the complete permitting process can be completed by November 3, 19B8. Even now the timing is such that it would be difficult to complete the time consuming and expensive permitting process in time to meet the existing deadline which was imposed by Congress. If the permitting process is not completed (permit in hand) by the November 3, 1988 deadline, the entire permitting process will have to be repeated.

Vista would still be dependent upon another company for the disposition of heavy ends. 3. Cost - Vista pays about #383,000 per year for sending heavy ends to PPG. 4. Heavy ends sent to PPG must be treated as hazardous waste and each shipment must be manifested and is subject to all hazardous waste shipping regulations. QQti.on_2_-_S4._Ea._SQQBRICH_CAIQXID_PRQQESS B. F. Goodrich has developed a CATOXID Process which uses a fluidized catalytic bed reactor to oxidize chlorinated hydrocarbon feed streams to HC1, water, and nitrogen oxides which are then fed to their Oxychlorination reactors to be used in the production of EDC. They have a CATOXID Unit in operation at their La Porte, Texas facility and have presented Vista with a terms proposal in which they would agree to accept up to 12 million pounds of heavy ends per year for a charge of #25 per ton. This would provide for the disposition of the current 11.4 million pounds produced annually at the VCM Plant. Since the heavy ends material would then be classified as a feedstock, and not as a hazardous waste, the environmental regulations applying to the shipping and handling would be less stringent allowing for the shipment of heavy ends under a bill of lading instead of having to manifest it as is currently done on shipments to PPG. Approval has been received from the Louisiana Department of Environmental Quality and the Texas Water Commis sion for this interpretation of applicable regulations. Two truckloads of pling and testing CATQXID Process. of the heavy ends heavy ends were sent to the La Porte facility for sam for compatibility with their other feedstocks and the They reported no difficulties in unloading and blending material. The estimated cost of sending the heavy ends to BFG would be #25 per ton for processing and #11.40 per ton plus about #20,000 per year for transpor-- tation casts for a total annual expense of about #227,000 per year to send 11.4 million pounds of heavy ends to BFG. An additional cost of about #50,000 would be required for secondary containment and piping revisions which would allow for railcar loading at the VCM Plant. When approached on the possibility of Vista purchasing the CATOXID Tech nology for use at the VCM Plant, BFG indicated that the current technology was not compatible with the oxygen-based fixed bed Oxychlorination Unit at the VCM Plant. BFG also indicated that they had no immediate plans of de veloping the required technology. The approximate cost of the La Porte CATOXID Unit, about #10 million, indicates that even a smaller unit, such as would be required at the VCM Plant, could not be justified at this time. ASVANIAGES CWH 0000083,, 1. Few capital modifications ($50,000) required. 2. Possible long-term solution to heavy ends disposition problem. 3. Eliminates the need to RCRA permit the VCM Plant incinerators to burn heavy ends. 4. Eliminates the need for secondary containment at heavy ends feed tank and pumps (about $55,000) as would be required for burning heavy ends. 5. Eliminates the need for revisions to the VCM Plant inci nerators, a savings of about $80,000. 6. Provides for a lower disposition cost than either PPG or incinerati on. 7. No potential effect on the stream factor for either the VCM Plant or the VCM Plant incinerators. 8. Heavy ends would not be classified as hazardous waste and would be subject to less stringent shipping regulations, with only a bill of lading required instead of a manifest. 9. Vista would have a signed contract with BFG with a guaranteed method of heavy ends disposition for a minimum of three years with less chance of being affected by future environmental regulations or solvent market conditions which would cause PPG to shut down the solvent process in which they utilize some of the heavy ends material. DISADVfiNIBSES 1. Vista would still be dependent upon another company for disposition of the heavy ends and would not recover any of the chlorine value in the heavy ends. 2. Increased expense and risk involved in shipping the heavy ends to La Porte, Texas although this would be minimized by the use of railcars instead of trucks. 3. Cost -- Vista would still have to pay about $227,000 annually for the disposition of the heavy ends. 4. Risk of having PPG arrange for another company to supply heavy ends material to fill the gap left by the heavy ends sent by Vista to BFG, thus eliminating a disposition option for that fraction of Vista heavy ends. QPIIQN_3_-_AERANaE_I0_fiiyiDE_IHE_HEAVY_ENpS_BEIWEEN_PPGzANP_BFG This option would involve negotiations with both PPG and BFG to reach an agreement with the two companies in which the shipments of heavy ends would be split between them. Provisions should be made which would allow the amount sent to each of them to be varied to meet current conditions. The most economical split would be to maximize the amount of heavy ends being sent to BFG while maintaining a share of PPG's demand. The PPG share should be maintained in order to prevent PPG from arranging for another company to fill the gap left by having Vista send heavy ends to BFG. QEIIQM_5_Z_BGRQ,,ESCDii_the_yCMi_PiantI_I.n5ineratgr s_t.o_.Bur n_Heavy_Ends Currently Vista has interim status to burn heavy ends in the VCM Plant incinerators. Unless a complete permit application, including a trial burn plan is submitted by August 8, 1987 this interim status will be lost. The complete permitting process must be completed by November 8, 1988 or the entire process must be repeated. The permitting process required for haz ardous waster incinerators is very time consuming and is expensive. CWH 000008313 S//^i //<jv HEAVY ENDS DISPOSITION OPTIONS SUEjMABY A study was made to examine several proposed options to provide -for the disposition of the heavy ends material produced at the VCM Plant as a by--product in the manufacture of EDO and VCM. The objective was to de termine whether the VCM Plant incinerators should be permitted to burn the heavy ends which would be classified as a hazardous waste material. This decision is required at this time since currently the VCM Plant has interim status for burning hazardous waste in the incinerators but in order to retain approval to do so a complete RCRA Part 2 permit appli cation, along with a test burn plan should be submitted by August 8, 1987. This is the expected latest date that aould allow sufficient time to complete the permitting process by the November 8, 1988 deadline set by Congress in the RCRA Amendments of If this deadline is not met, then Vista would lose the option of burning heavy ends in the VCM Plant incinerators until a complete r eappl i cat i on can be submitted. The following options were examined : Option 1 - Continue to send the heavy ends to PPG without a signed tract, possibly negotiating for a lower cost and a signed contract in the future. con Option 2 - Obtain a contract with B. F. Goodrich to have them process the heavy ends material in their La PorteCATOXID Unit to recover the chlorine as HC1 which is fed to their Oxychlorination Unit to produce EDC while generating high pressure steam. Option 3 - Obtain a contractual agreement with B. F. Goodrich and approval from PPG which would allow Vista to send heavy ends to both plants with about an even split between the two. This would provide two disposition options thereby making Vista less dependent on one industry for the outlet of heavy ends, would allow for price negotiations with PPG, and would like ly result in cost savings. Option 4 - Permit the VCM Plant incinerators to burn heavy ends and perform the required revisions to allow for this operation. Option 5 - Permit and construct heavy ends at the VCM Plant. a new hazardous waste incinerator to burn Option 6 - Commercial incineration of all heavy ends by participation in take-or-pay arrangement with a company such as Chemical Waste Management or Gulf Coast Waste Disposal Authority. a Option 7 - Negotiate an arrangement with Georgia Gulf in developing a pro cess similar to the CATOXID Process of B. F. Goodrich, possibly building such a process unit at or near the VCM PLant. The results of this study indicate that the best option would be Option 3: Continue to send heavy ends material to PPG while negotiating a contract with B. F. Goodrich and then to split the shipments of heavy ends material CWH 000008310 between the two companies. This would provide two disposition options and would allow for -future price negotiations. It should also provide -for an annual savings o-f about ... ' relative to the current cost of sending all of the material to PPG. This option would also provide a two to three year period in which other options, such as the Georgia Gulf process, could be examined or developed. dEa^^^EtlDS_DISEQSlIIQtJ_QEIIQt}S QEXIQb!_i,,=:_QQNIItilUE_IQ_SEb|D_HEayy_gNDS_XQ_PPS Currently Vista sends all of its heavy ends to PPG where some of the ma terial is recovered in one of their solvent processes and the remaining material is incinerated. There is no signed contract and future environ mental regulations or changes in the solvent market could result in PPG refusing to accept the Heavy Ends upon a sixty-day notification. Currently this would leave Vista with no other disposition option except for commer cial incineration which has an estimated $4--7 million annual cost. Currently Vista pays about $383,500 annually to send about 11.4 million pounds of Heavy Ends to PPG. This material is shipped by truck and each shipment must be shipped under a hazardous waste manifest and can be re fused for various reasons, (such as difficulty unloading due high solids content). Each of these refusals necessitates state and federal notifi cation in which the reason for refusal is given along with what was done to correct the problem. ADVANTAGE*! 1. No need for permitting or modifications to the VCM Plant incinerators. 2. No potential affect on the stream factor of the VCM Plant or the incinerators. 3. No capital modifications required. DISADVQNIAGES HUH 00000(3311 1. Risk of having to resort to commercial incineration or other option The timing is such that it would be difficult to have the required work completed in time to meet the existing deadlines. Some studies and test burns have been completed to determine whether the heavy ends could be successfully burned in the VCM Plant incinerators. Previous test burns were only partially successful but John Zink repre sentatives feel that it is possible. The major problem which would be encountered would be the need to remove essentially all of the sodium present in the heavy ends. Past studies indicate that the newly-installed static mixers in conjunction with a mesh coalecsence system should lower the sodium concentration in the heavy ends to an acceptable 10-20 ppm. The presence of sodium in the feed to the incinerators can cause excessive fouling of the waste heat boiler tubes and severe damage to the refractory lining, requiring frequent cleaning of the tubes and possibly annual replacement of the refractory lining.Bath of these would result in greater downtime for the liquid-burning incinerator which would increase the risk of having incinerator bypasses since the downtime required to re place the refractory is estimated to be three to four weeks during which time the VCM Plant would have no back-up incinerator should there be a problem with the on-line incinerator. Recent tightening of the regulations and enforcement practices pertaining to the number of incinera tor bypasses and stack exceedances cause this added risk to be highly undesirable and possible costly in the future. ADVANI^gES 1. This option would provide for in-plant disposition of heavy ends with no dependency upon other companies. 2. Some possible revenues from increased steam and muriatic acid production, although these revenues would be nearly negligible since the extra steam has little current value and the market for muriatic acid is nearly non-existent, especially for the low-grade acid which would be produced. 3. Savings of costs for sending Heavy Ends to PPG or BFG ($227,000 3S3,000/year). 4. Lower capital expenditure when compared to building a new hazardous waste incinerator dedicated to Heavy Ends. ADVANTAGES 1. Higher risk of incinerator bypasses and the resulting possible increased enforcement measures by environmental agencies. This increased risk is due to: a> higher feed rates to the incinerator resulting in a lower tolerance for possible upsets in the vent flows and b) more downtime required for more frequent maintenance including a possibly annual 3-4 week downtime required for refractory replacement ($90,000) 2. Increased maintenance cost - about $107,000 per year 3. RCRA permitting costs ($130,000) and timing requirements 4. Modifications required for sodium removal ($70,000) 5. Additional incinerator instrumentation required by RCRA regulations, (carbon monoxide monitoring system and fuel shut-off controls, casting CUH 0000083.14 6. 7. 8. 9. 10. about $80,000). Need -for secondary containment around the heavy ends feed storage tank and feed pumps (about $55,000). Risk of reducing the stream factor for both the incinerators and the VCM Plant Possible capital modifications which may be required to achieve the required 99.997. destruction efficiency (not likely to be needed) The VCM Plant would become a hazardous waste disposal site and subject to any applicable regulations Engineering/envirionmental manpower requirements QEIIQN 5 - CQNSIEUQI &NQ EERMII & NEW INQ1NERAIQR IQ BURN HEQVY ENJDS A quick examination of the option of constructing and permitting a new haz ardous waste incinerator to burn heavy ends and possibly other Vista generated wastes indicated that this option would not be desirable at this time. If built at the VCM Plant it would cause the VCM Plant to be classi fied as a hazardous waste disposal site and subject to all applicable regu lations. The estimated cost ($5-10 million plus an undetermined operating cost) is not justifiable at this time. QDyANjeGES 1. Could provide capacity to process much of Vista's hazardous waste materials. 2. Would be more capable of meeting the required destruction efficiencies for all types of waste produced by Vista. 3. Would eliminate the risk of decreasing the stream factor of the VCM Plant or its incinerators QISADyeNJABgS 1. 3-5 years would be required before start-up of the new incinerator. 2. The VCM Plant would became a hazardous waste disposal site and subject to any applicable regulations and enforcement measures. 3. Estimated cost - $5-10 million plus an undetermined operation cost. QPIIQClj_6_z_aMMRGieL_INGJNERAIIQN^gP_ALL3_HEAyY_END I This option would involve Vista participating in a take-or--pay arrangement with other companies in which the expense of constructing, permitting, and operating a commercial incinerator would be shared by the companies which would send material to be incinerated. Usually the companies subscribing to the incineration services must agree to supply a certain fraction of the feed material to the incinerator or to pay the required minimum fee for processing that amount whether they send it or not. Currently bath Gulf Coast Waste Disposal Authority and Chemical Waste Man agement are proposing such arrangements. In the case of the Chemical Waste Management proposal the subscribers would be required to supply eighty per-- cent of the capacity of the incinerator for a period of three to four years depending on the required payback period. After the payback period, each CUH 0000083IS 1-/1S/87 subscriber would have an annual right o-f first refusal to renew its origi nal capacity commitment or to reduce its commitment if so desired. A simi lar arrangement should be available from Gulf Coast Waste Management Au thor i ty. AD^ANTAgES 1. Secure, long-term solution to heavy ends disposition problem 2. No need to permit and revise the VCM Plant incinerators 3. No demand on Vista engineering manpower required 4. No possible affect on the stream factor of the VCM Plant BISaSyANJAGgS 1. Cost - estimated to be $7-9 million annually 2. No provisions for interim disposal of heavy ends while the incinerator is constructed (possibly in 1990) 3. Increased risk of transporting hazardous waste further distances 4. Increased onsite and offsite storage capacity may be required. 5. No raw material or energy recovery by Vista 6. Vista would have to commit to a take-oi--pay arrangement with the constructing the incineration facility with no payback or payout possible. OPTION 6 - NEGOTIATE AN ARRANGEMENT WITH GEORGIA GULF Georgia Gulf has been working on developing a process similar to the CATOXID Process of B. F. Goodrich which could be of value to Vista for pro cessing heavy ends. They has been some tentative contact with them and the initial impression is that they would possibly work with Vista in the de velopment of this process. They currently don't have this process in oper-- ation and are probably several years away from doing so. aeyayiAG^s 1. Possible long-term solution to heavy ends disposition problem 2. Future bargaining tool for negotiating pricing and terms with both PPG and BFG 3. Might be feasible to build a CATOXID-like unit at or near the VCM Plant as either a joint venture with Georgia Gulf or by licensing the technology from Georgia Gulf and constructing the unit ourselves. 4. Possible revenues from the recovery of the chlorine and energy value of the heavy ends. DISADVANTAGES 1. This option is still several years away from possible operation. 2. No firm commitment or proposal from Georgia Gulf is expected at this time. 3. May not be economically feasible due to the possibly high capital expenditure required for the development and construction of this process. ooooo**6 To__ VISIAFrom Calculation Sheet Sec* or* ' C Jt o fo-.'JQ.O U P h ?
