December 22, 1982 CHRONOLOGY OF DIOXIN INCIDENTS IN MISSOURI Date May 1968-Feb. 1969 November 18, 1969 December 1969 April 15, 1970 (through January, 1972) November 30, 1970 (through December 4, 1970) Late '70 or Early '71 Event Hoffman-Taff was producing 2,4,5-T for military (U.S. Army), production wastes disposed by Conservation Chemical Co. Hoffman-Taff leased building in Verona, Missouri to NEPACCO. Syntex acquired Verona facility from Hoffman-Taff. NEPACCO started production of hexachlorophene-- 2,4,5-TCP distilled to make hexachlorophene-- dioxin formed in TCP production-- still bottoms contained TCDD. Three wastes streams were disposed of as follows: (1) still bottoms-- two shipments of approximately 6000 gallons each were incinerated by Rollins Environmental Service Co. (nee Rollins Purle, Inc.) in Baton Rouge, LA; six shipments of approximately 3000 gallons each were removed by Bliss Waste Oil Co.; approximately 4300 gallons remained in storage tank at Verona Facility; (2) wash water waste-- between 225,000 gallons and 540,000 gallons were transported by National Oil and Supply Co. to the Water and Waste Management School in Neosho, MO for treatment and disposal; an additional unestimated amount was discharged to on-site lagoons at the Syntex plant in Verona; (3) diatomaceous earth filter material-- majority of unestimated amount disposed at Baldwin Park (nee Aurora municipal dump) with lesser amounts taken by local farmers (Denney, Erwin, and Rusha farm sites). Initial waste from NEPACCO production was taken to Rollins in Baton Rouge, LA for incineration-- 12,600 gallons still bottoms. Russell Bliss was hired by Independent Petrochemical to haul waste from Verona. w IFWrotectwe order. SUBJECT to P Y 'O February 16, 1971 March 23, 1971 April 1-8, 1971 May 20, 1971 May 25, 1971 May 26, 1971 May 30, 1971 June 11, 1971 June 16, 1971 July 1971 July 1971 2 Bliss picked up first load of NEPACCO waste, mixed waste with waste automotive oil in storage tank, ultimately sold as salvaged oil to one of two refiners (Midwest Oil and Refinery or M.T. Richards Co.); est. 3000 gallons. NEPACCO caught fire. Syntex closed their //4 and //5 trenches. Russell Bliss removed 3,500 gallons of still bottoms. Truck ticketed as being overweight. Delbert Eskew, driver for Bliss, off-loads about 500 gallons of still bottoms on road at Bliss farm (reportedly without spray attachment) to reduce weight before continuing on to St. Louis. Shortly thereafter, 70 chickens and 1 dog die. The Bliss farm consists of about 90 acres and is located in N1/2, Sec 12, T38N, R6W, Phelps County. Bliss removed 3,000 gallons of still bottoms used almost entirely to "oil"Shenandoah Arena at Moscow Mills (Lincoln County) for dust control. Gary Lambarth, driver for Bliss, sprayed arena with 2,000 gallons of what appears to be straight still bottoms containing approximately 306-356 ppm dioxin for an estimated total dose of 6.1 lb TCDD; remainder applied to Bliss'Mid-America arena in Ellisville. First horse became sick. From this date on, 62 horses belonging to Piatt and Hampel, plus 12-13 other horses, die or are destroyed. Hundreds of sparrows were found dead on floor of arena at Shenandoah Stables; horses became ill. During next few weeks, more wild and domestic animals affected with most of them dying; human illness noted during horse show this date. Bliss oils Bubbling Springs Arena at Fenton (St. Louis County). Arena 115' x 224' in size. Bliss oils Timberline Stables near New Bloomfield (Callaway County). Arena 78' x 138' in size. NEPACCO took material to Denney Farm. Shortly after oiling at Timberline Stables, animals began to die. The first of these was a cat which developed sores around the eyes and began losing hair. Five more kittens died shortly thereafter. A dog, many birds, mice, and an opossum also died during this period of time. July 15, 1971 July 30, 1971 August 21, 1971 CDC memo 3-24-71 Appendix 2 ' Document //I August 22, 1971 August 23, 1971 CDC memo 8-24-71 Appendix 2 Document //I h August 1971 September 8, 1971 October'1971 October 4, 1971 ' October 25, 1971 October 30, 1971 November 1971 i 3 Piatt and Hampel of Shenandoah Arena suspicious about "oil"-- called Bliss-- no indications of source or problem with "oil". Bliss removed 3,000 gallons of still bottoms. May have been sold as salvaged oil to one of two refiners. Six-year-old daughter of Shenandoah arena co-owner develops and exhibits hemorrhagic cystitis and is admitted to St. Louis Childrens Hospital the following day. Hampel (owner) cleared out Shenandoah arena, stopped horse shows, Hampel removed 6 to 8 inches of soil which was placed in new highway fill in front of stables. Estimated about 350 yards of contaminated soil. Fresh soil put back in arena. Division of Health notified by the Centers for Disease Control (CDC) of contact from girl's physician requesting assistance; Division of Health issues invitation to CDC to participate in an investigation of situations. Symptoms of human illness resolve with cessation of exposure to arena; horses continue to sicken and die until January 1974 when almost all of the 85 horses originally exposed have died. CDC took soil samples at Shenandoah Arena. NEPACCO denied, by Syntex, further use of lagoons on Syntex property. Shenandoah Stables arna excavated again by Hampel to depth of 12 inches and refilled with "clean river bottom soil"; excavated soil put in road fill for U.S. Highway 61, then under construction immediately adjacent to stable property. * Bliss removed 3,000 gallons of still bottoms. Bliss removes last 3,000 gallons of still bottoms fot total estimated 18,500 gallons. National Oil and Supply started trucking wastewater to Neosho Digester at Water and Wastewater Technical School, a total of 225,000 gallons. Hampel & Piatt started bringing horses back in to Shenandoah Stables. Animals continue to get sick and/or die. Late 1971 January 10, 1972 Early 1972 February 8, 1972 April 1972 July 1972 August 4, 1972 August 14, 1972 CDC Memo 8/14/72 Appendix 2 Document //2 Late 1972 March 1973 August 1973 Nov.-- Dec. 1973 March 4, 1974 DGLS Letter 3-7-74 Appendix 2 Document //3 4 A three-year-old boy who lived at the Timberline arena in 1971 developed chloracne, "gastrointestinal illness with nausea, vomiting, and abdominal pains. He also complained of headache." Symptoms first appeared six weeks after arena was treated with contaminated oil. Was first seen by doctor in July 1972. NEPACCO made last batch of Hexachlorophene. Two horses died at Bubbling Springs Arena. Additional TCDD-contaminated wastewater taken to Neosho. Hampel removed 790 to 1,060 yards of soil and placed in slough area adjacent to stables at Shenandoah Stables. Chemical odor still present when area wetted down. A veterinarian, from the School of Veterinary Medicine, UMC, obtained a soil sample from the Timberline arena for analysis. The protective equipment that he was wearing left part of his face exposed. A "gas" that was emanating from the soil burned the subject's face, from which he had "keratoses" for at least one year. At Timberline Stables, approximately 12" of contaminated soil (400 yards) removed and buried in a Jefferson City sanitary landfill. In all, 12 horses died at this arena. At least two other animals became ill and recovered. "Final" report of investigation at horse arenas issued by CDC; no clear-cut toxicant identified, but some unknown organphosphorus compound implicated. Three more horses die at Bubbling Springs Arena. Vern Stout excavated soil (approximately 850 yards) from Bubbling Springs arena and used as fill at two locations including Minker residence and Vern Stout residence. Seventh and final horse dies at Bubbling Springs Arena. This animal had been sick for a year. Six other sick horses recover. Shenandoah Arena sold by Piatt & Hampel, to Marlene Hudsteth & Bob Grizzle. Dr. Jim Williams of the Division of Geology and Land Survey (DNR) shows concern about conditions at Hoffman-Taff (Syntex) property. July 1, 1974 July 15, 1974 July 30,1974 August 2, 1974 CDC Memo 8/8/74 Appendix Document //6 August 2, 1974 DOH Memo 8-5-74 Appendix 2 Document #4 August 3, 1974 CDC Memo 8-5-74 Appendix 2 Document #5 August 8, 1974 August 9, 1974 August 10, 1974 5 Dept, of Natural Resources (DNR) was established as a result of State Reorganization Act. At Timberline a three-year-old gelding horse died. Autopsy showed "emaciation, dermatitis on both hind fetlocks, defuse, supporative pleuritis, and ulcerative gastritis." Shenandoah Arena samples collected by CDC in August 1971 found to yield the following results: TCP 0.56 to 0.6 percent (5,600 to 6,500 ppm) TCDD 31.8 to 33 ppm PCB 1,350 to 1,590 ppm CDC informs Division of Health of latest findings and accepts invitation from Dr- Denny Donnell, State Epidemiologist, to participate in renewed investigation. CDC followed up with memo on August 8. DOH contacted Russell Bliss concerning spraying of Shenandoah Stable with toxic substances. Heath (CDC) shows concern for future health effects studies concerning persons exposed to toxic substances in Lincoln County. Two EIS physicians (Drs. Coleman Carter and Matthew Zack) from CDC are met in St. Louis by Dr. Patrick Phillips, then Division of Health Public Health Veterinarian; after reviewing previous investigation and updates, began current phase of field investigation by traveling to Shenandoah Stables near Moscow Mills and talking with Marlene Hudsteth (present co-owner with Bob Grizzle) concerning previous dioxin incident; obtained current information on animal and human health and samples of soil and wood from arena. Phillips informed Carter and Zack of probable involvement of Timberline Stables near New Bloomfield because of similar illnesses in horses and spraying of arena by Bliss Waste Oil in 1971; Carter and Zack informed Phillips of origin of TCDD in TCP production; investigation planned. Phillips, Carter and Zack traveled to Timberline Stables and interviewed Robert Hand (owner) and Hamp Ford (attorney) concerning animal and human illnesses experienced in 1971; obtained history of arena, including excavation, and names of contacts for further information on human illnesses. August 11, 1974 August 12, 1974 August 13, 1974 August 14, 1974 August 15-16, 1974 August 19, 1974 August 20, 1974 Phillips, Carter and Zack met with Judy Piatt and reviewed original information on dioxin incident at Shenandoah Stables; explained toxicity and effects of TCDD and referred all exposed originally to family physicians for evaluations; updated information on health condition of animals and humans; received information of private investigation of Bliss Waste Oil Co. by Piatt and Hampel. Carter and Phillips interviewed Russell Bliss and obtained lists of sources (other than service stations) of wastes in 1971 and sites and dates of "oiling" in 1971. Obtained samples from MidAmerica Arena and soil by storage tanks. Results of analysis showed 0.15 ppm TCDD from Arena sample. Arena reportedly never excavated-- Bliss did not report any deaths of horses. Bliss indicated sprayed arena once a month between 1960-1974. Carter and Zack telephoned waste sources as supplied by Bliss to ascertain possible TCP . production but no success; Phillips telephoned sites "oiled" by Bliss and discovered that Bubbling Springs Ranch had similar horse illnesses as two other arenas. Phillips interviewed various members of Bubbling Springs Ranch and obtained information on animal and human illnesses; also obtained information on subsequent disposal sites of excavated arena soil; interviewed Vern Stout and Valerie Minker concern ing soil excavated from Bubbling Springs Ranch arena and learned that soil was deposited at Minker residence in March 1973; informed both of probable dioxin contamination and obtained samples of soil for analysis. Samples at Stout residence found to contain 0.44, 0.43, 0.17 ppm TCDD. Samples at Minker residence found to contain 0.085, 0.38, and 0.74 ppm TCDD. Phillips finished calling sources of wastes and sites of oiling with no further success or discoveries; Carter and Zack return to CDC in Atlanta with samples for analysis. Carter and Zack (CDC) contact various chemical producers with no apparent success. Carter contacted the Defense Contract Administra tion Services Regional Office in St. Louis for information on companies once under contract to the U.S. Army for production of 2,4,5-T; in Missouri, these companies were Monsanto, Thompson ' 6-TW;.-. August 23, 1974 August 24, 1974 CDC Report 8-24-74 Appendix 2 Document #7 August 26-28, 1974 f-:. August 28, 1974 August 29, 1974 7 Hayward, Hoffman-Taff and Thompson Chemical Company; after contacting and questioning each company on disposal of wastes via Bliss Waste Oil, it was learned that NEPACCO (North East Pharma ceutical and Chemical Co.) had bought equipment and leased plant space from Hoffman-Taff (since acquired by Syntex Agribusiness, Inc.) and had used Bliss for disposal of some of its wastes; it was also learned that a tank containing approxi mately 4300 gallons of distillation residue wastes from NEPACCO's operation was still existant on Syntex plant property at Verona. Zack interviewed Edwin Michaels, President of NEPACCO, about production history of Verona plant and disposal of wastes; also interviewed Rick Bagby, former plant manager for Syrrtex's Verona plant about NEPACCOfs operation. CDC summarizes dioxin incident in Weekly Report. Zack had further conversations with Rick Bagby and Bill Ray, plant manager of NEPACCO plant in Verona; Ray confirmed use of Bliss Waste Oil to dispose of wastes; also spoke with a Dr. Layton of Water and Waste Management School near Neosho concerning certain wash water wastes from NEPACCO's operation and learned that approxi mately 150,000 gallons of these wastes were received and put into an old sewage digester tank at the school; much has evaporated, leaving a tarry residue, and tank was being filled with debris and soil from new sewage plant construction site. Zack again spoke with Edwin Michaels concerning disposal of NEPACCO Verona plant wastes via Bliss Waste Oil; Michaels could only recall disposal company but promised to review plant records; also contacted Russell Bliss to verify allegation that he received chemical wastes from NEPACCO plant at Verona; Bliss stated that he had recalled a contract with Independent Petrochemical Co. to haul waste material from a company in Springfield area in 1971; Bliss also said that some of this waste material was sprayed on his farm near' St. James. Michaels called Zack with further information on waste disposal from Verona plant; three compaines were involved: Rollins Purle Inc., Independent Petrochemical Co., and National Oil and Supply Co. August 30, 1974 August 31, 197^ August 1974 August 1974 August 1974 September 4, 1974 Carter/Zack had further conversations with Dr. Layton concerning delivery of NEPACCO wastes at Water and Waste Management School in 1971-72; also talked with W. L. Gears, manager of National Oil & Supply Co., about disposal of wastes from Verona plant; Gears confirmed transport of waste from NEPACCO plant in Verona to Water and Waste Management School in Neosho; also interviewed a Mr. Calcaterra of Independent Petrochemical and learned that they had sub-contracted to Bliss Waste Oil for removal and disposal of wastes from NEPACCO's Verona plant; then contacted Bliss again for actual dates of removal, which he related as February 16, 1971, May 20 and 25, 1971, July 30, 1971, and October 4 and 25, 1971; Bliss stated that IPC gave him sample of waste which he later discarded; Bliss remembered that wastes had "stuffy creosol smell" and were "very heavy." Phillips (DOH), Carter and Henning Eklund (CDC Industrial Hygienist) traveled to Syntex Agri business Inc. plant in Verona, former site of NEPACCO operations, and spoke with Godfrey Moll, Syntex V-P in charge of operations, and Bill Ray; historical information.pertaining to HoffmanTaff's 2,4,5-T production for the U.S. Army and subsequent NEPACCO hexachlorophene production was obtained; also samples of NEPACCO still bottoms waste were collected for analysis. Two soil samples were collected on Bliss farm road by CDC investigators show 0.46 andO.61 ppm TCDD. CDC collects samples at Timberline. Trace amounts of TCP found. At Shenandoah Arena, (CDC) samples collected from arena floor found to contain a trace amount of TCP and no detectable concentrations of TCDD or PCB. Bubbling Springs Arena sample negative, handwritten notation in CDC notes indicates "trace (?)." Zack talked with Lyle Jordan, marketing represen tative for Rollins Environmental Service Co. in Baton Rouge, LA, about "still residues" wastes from NEPACCO plant in Verona; this was confirmed by Jordan who said that the waste load was incin erated at Rollins plant in LA; also spoke with Glen Gettinger, manager of Midwest Oil and Refinery Co., about nature of operation and disposal of oil from Bliss Waste.Oil Co.; Gettinger stated that refinery's clay filter material was all disposed at Simpson Sand and Gravel Co.; Carter spoke with Bliss again concerning deposition of dioxin wastes on his farm near St. James; Bliss said that truck received ticket at weigh station September 6, 1974 September 10, 1974 September 11, 1974 Draft Memo 9-11-74 Appendix 2 Document #8 October 2, 1974 CDC letter, 10-2-74 Appendix 2 Document //9 October 30, 1974 CDC Letter 10-30-74 Appendix 2 Document //10 December 2, 1974 DOH Memo 12-2-74 Appendix 2 Document //10a January 1975 February 24, 1975 DOH Memo 4/4/75 Appendix 2 Document 11 Mid-March 1975 outside Springfield for being overweight at end of May 1971; Bliss claimed that the driver was Delbert Eskew and that Eskew sprayed the wastes on Bliss's farm so as not to be overweight at the next weigh station. Interview with Mr. Richards of M.T. Richards, Co., Crossfield, IL; sludge from refinery process spread on oil field roads, usually within two mile radius of plant area; samples collected for analysis from oil field roads. Information obtained from Missouri Division of Motor Vehicles reveals that an overweight citation was issued to Delbert Eskew, driver of Bliss Waste Oil Co. truck, at Stafford weigh station on May 20, 1971; truck left weigh station without reducing its load; truck subsequently stopped at Bliss Farm near St. James and emptied some of the wastes on dirt farm road before continuing trip to St. Louis. Phillips' memo to Dr. Domke (DOH Director) with preliminary report of investigation. Memo emphasized "draft" nature of report and that investigation was continuing. Heath's letter to Dr. Donnell expressing concern for safe and prompt destruction of remaining wastes in storage tank at Verona facility; suggested incineration of wastes with deep-burial of tank after sealing and marking; recommended appropriate handling safeguards and that persons involved with disposal be properly informed of hazard posed by TCDD. Carter's letter to Phillips outlining cornerstones for effective hazardous waste management legislation. Domke requests ideas for legislation on hazardous waste management. DNR initiates hazardous waste project which was primarily a survey of current hazardous waste generators to determine type and quantity of waste being generated. Press release announcing Syntex's intention to find a "permanent solution to the problem" in Verona. Phillips' telephone conversation with Jim Whitley of Department of Conservation advising him of dioxin investigation and NEPACCO's Verona plant. I >.

Report indicates halflife of dioxin is approximately one year. Phillips provided Domke an outline of legislation for hazardous waste management. Phillips updates Domke (DOH director) concerning the dioxin investigation. Letter from Missouri Division of Health to Solid Waste Representative, EPA - Region VII providing state report on investigation of arenas. Domke encourages working with DNR on legislation. Phillips met with EPA, Department of Natural Resources and Syntex officials in efforts to effect disposal of tank wastes; interviewed various producers of incineration, systems and operators of commercial incinerators in attempt to solve problem. CDC and DOH personnel author paper in science Vol. 188 concerning dioxin at Missouri Horse Arenas. Joe Eigner (Director of DNR Hazardous Waste Project) updated Kenneth Karch (Director, DEQ) on the dioxin problem. Recorrcnends DOH to continue investigation and DNR to draft legislation concerning hazardous waste disposal. Bob Lindholm (AG office) informed Kenneth Karch that precautionary action should be taken to prevent harm to residents where Bubbling Springs arena soil had been used as landfill. July 24, 1975 DNR Memo 7-24-75 Appendix 2 Document #16 June-July 1975 March 5, 1976 DOH Memo 3-5-76 Appendix 2 Document #l6a March 1976 April 9, 1976 EPA VII Letter 4-9-76 Appendix 2 Document #17 April 14, 1976 AG Memo Appendix 2 Document #18 August 1976 September 1976 September 8, 1976 DNR Letter 9-8-76 Appendix 2 Document #19 September 29, 1976 CBNS Paper : 9-29-76 Appendix 2 Document #20 11 Robert Robinson (Director of Solid Waste Management Program, DNR) and Joe Eigner updated Kenneth Karch on dioxin investigation. Recommendation made to have CDC resample soil at Stout and Minker property and wells in area be sampled for dioxin. Also questions as to whether soil removal is needed three years after the fact if dioxin has a half-life of one year. State investigation continues. Phillips contacted by Dr. Ralph Ross of EPA concerning detection of dioxin in beef fat tissue samples from three Missouri counties; after check ing with known and potential dioxin sources and Division of Geology and Land Survey, concluded that source of dioxin in beef fat tissues probably not related to NEPACCO incident. EPA, DNR and DOH continue to confer with Syntex officials about latest efforts to incinerate tank wastes; ultimately realized that transport out-ofstate was impossible due to lack of cooperation of intervening states and states of possible receipt. Jrome Svore (Regional Administrator of Region VII of EPA) informed Robert Lindholm (AG's office) that EPA, DOH, DNR and Syntex are continuing to look for disposal options. Svore also suggests land burial as an option. Bob Lindholm informed Phillips of land burial option and adds that this would not be a "long term" option. At Shenandoah Arena, dog named Scotty died after unearthing leg of horse buried on property. Phillips returned to Minker/Stout sites - noted that soil was stable - took new samples and sent them to CDC. Joe Eigner informed Bertha Parsons (concerned citizen) that the EPA and DOH are looking for alternatives for the disposal of the dioxin waste in Missouri. Also that DNR is assisting DOH in the investigation. DNR is also proposing legislation to prevent this situation from-' reoccurring. Barry Commoner publishes report entitled Accidental Contamination of Soil with Dioxin Missouri: Effects and Countermeasures. Paper outlines investigation and states that half-life of dioxin in soil is between 1 year and 0.24 year. Recommends further study. October 1976 1976 1976 December 1976 January - June 1977 July 1977 August 1977 September 6, 1977 DOH Memo 9-6-77 Appendix 2 Document 20a October 1977 April 1978 12 DNR and League of Women Voters organize pre-legislative session conference on proposed state Hazardous Waste Management Bill sponsored by Rep. Wayne Goode; Phillips re-samples Minker and Stout sites. Toxic Substances Control Act (TSCA) and Resource Conservation and Recovery Act (RCRA) passed; state law drafted. Syntex begins work on disposal options - contents of tank at Syntex's Verona facility is major concern because of 3^3 ppm concentration of TCDD. Missouri Legislative Conference on Hazardous Waste; Missouri House Bill (318) pre-filed. DNR continues working on Hazardous Waste Management Bill being considered by legislature. Passage and enactment of Missouri Hazardous Waste Management Act, requiring registration of generators, licensing of transporters and permitting of disposal facilities, with definitions (RSMo 260.350 through 260.^30, 1978). More meetings between Department of Natural Resources, Division of Health, EPA and Syntex concerning destruction/disposal of tank wastes; Syntex official (Godfrey Moll) reported on investigation of new process called photolysis which involves ultraviolet light to strip chlorine atoms off dioxin molecule, thereby de-toxifying the compound; as more research completed, photolysis technique became more and more promis ing; finally decision reached to destroy dioxincompound of tank wastes by photolysis in September of 1979. Domke encouraged incineration of dioxin. Missouri Hazardous Waste Management Law signed by the Governor. Hazardous Waste Management Commission appointed by Governor; DNR begins drafting Hazardous Waste regulations. May 30, 1978 EPA Letter 5-30-78 Appendix 2 Document #21 December 14, 1978 Governors Letter 12-14-78 Appendix 2 Document #22 February 21, 1979 DOH Memo 2-21-79 Appendix 2 Document #23 February - June 1979 March 29, 1979 September 11, 1979 EPA Letter 9-11-79 Appendix 2 Document #24 October 1979 DOH 11-7-79 and 11-8-79 Appendix 2 Documents #25, 26 October 2, 1979 October - November 1979 November 19, 1979 DNR Memo 11-19-79 Appendix 2 Document #27 November 19, 1979 DNR Memo 11-27-79 Document #28 EPA Region VII informed Robbie Robinson (Director of Solid Waste Management Program in MDNR) that the request for EPA mobile incinerator to be used to destroy waste dioxin at Verona was being processed.
