OVERVIEW OF 1987 INDUSTRIAL HYGIENE PROGRAM A. INTRODUCTION The Environmental Monitoring Program of the Dow Syngas Project, commonly referred to as LGTI - Louisiana Gasification Technology, incorporated, is detailed in the Environmental Monitoring Plan (EMP) of the Project. The EMP was submitted to the U. S. Synthetic Fuels Corportation (SFC) and its Consulting Agencies in accordance with the requirements of the Energy Security Act, and the Price Guarantee Commitment between LGTI, the Dow Chemical Company and SFC. The EMP details Industrial Hygiene Monitoring for LGTI, synergistically combining the monitoring guidelines of Dow with those of the SFC. B. SUMMARY/RECOMMENDATIONS The Dow Syngas Project, commonly referred to as LGTI - Louisiana Gasification Technology Incorporated, completed construction during March of 1987, and commenced with start-up and initial operations at that time. Industrial Hygiene efforts during 1987 were mainly directed toward program development and initial implementation. A number of process and area audits were performed to assist with placement of area monitors, selection of personal and protable monitors and development of Physical and Chemical Agent Inventories. Extensive monitoring for hydrogen sulfide and carbon monoxide occurred during the year, in addition to less frequent monitoring for noise, dust and benzene soluble organics. Industrial Hygiene monitoring performed to date confirmed area monitor locations, defined the basis for personnel protective equipment requirements, and indicated areas of potential exposure such that corrective measures could be taken to eliminate the exposure. Typical levels of hydrogen sulfide and carbon monoxide detected were well below the TLV's for the compounds. A more pronounced effort for Industrial Hygiene monitoring is planned for 1988. C. CONCLUSIONS Industrial Hygiene monitoring performed during the start-up and initial operation of LGTI confirmed the need for area and personnel monitoring for hydrogen sulfide (H2S) and carbon monoxide (CO) to warn for potentially serious situations as a result of process leaks. Monitoring for noise and dust provided information to determine minimum requirements for personal safety equipment. Data from the organics testing performed will be used to establish future monitoring programs for the compounds, with the goal of eliminating exposure to the Benzene Soluble Organics. Industrial Hygiene monitoring at LGTI will continue and increase during 1988, as operation of the facility becomes more routine. All personnel classifications, and various operating conditions will be monitored. DO 099954 CONFIDENTIAL LGTI SURVEY, 1987 Page 2 II. 1987 LGTI EXPOSURE EVALUATION A. MONITORING PROGRAM RATIONALE Construction of the LGTI facility continued through the first quarter of 1987, with the Construction-Stage Health and Safety Review of the Project held on January 27, 1987. Each area of the workplace was audited by a number of Industrial Hygiene, Safety, Research, and Engineering Professionals. Pre-operational process area audits established the following hazard parameters to be monitored during operation as well as maintenance: Area* Parameter A. Coal Handling Dust Noise B. Coal Gasification and Particulate Removal Heat H2S CO Noise Selected Organics Particulate Matter C. Sulfur Removal and H2S D. Incineration of Waste Gas S02 H2S Heat *See Figure 1 (Figures found in Appendix 1) for area designations. B. PERSONNEL MONITORING Some personnel monitoring occurred during 1987 for noise, dust, organics, CO and H2S. Much of 1987 was spent developing appropriate mechanisms for documenting and reporting industrial Hygiene data. The LGTI Process Area Access Policy (See Appendix 2) require CO and H2S monitors for entry to certain locations. This monitoring, though extensive, was not documented during 1987. For 1988, data will be collected from the CO and H2S monitors to document actual exposures. Personnel monitoring data gathered in 1987 is included as Appendix 3. DO 099955 CONFIDENTIAL LGTI SURVEY, 1987 Page 3 C. AREA MONITORING A number of area monitors for CO and H2S are located throughout the LGTI plant (see Figure 2). This monitoring has been operational since startup, and is utilized to warn of leaks and potentially hazardous situations. In addition, some area monitoring for noise occurred during 1987. As a result of noise testing at the..coal unloading area, hearing protective equipment requirements were increased during this operation. The entire process area has been designated to require hearing protection for entry. This data is included as Appendix 4. D. PROCESS AREA SURVEYS Industrial Hygiene and Environmental surveys of the process areas were also used as the basis for generating Chemical and Physical Agent Inventories for the sixteen worker classifications associated with LGTI operations and maintenance. DO 099956 CONFIDENTIAL LGTI SURVEY, 1987 Page 4 III. 1988 SURVEILLANCE PROGRAM A. RATIONALE In order to protect the employees from overexposure to concen trations of chemicals in the air or through skin contact, dust, noise, or heat, the industrial hygiene monitoring for LGTI will use personnel monitoring for C02, S02, and NH3 with the use of Drager (R) Tubes; personal, portable and area monitors for H2S and CO; personnel sampling pumps for dust; sound level meters and noise dosimeters for noise: and oxygen/combustibles detectors for vessel entry. The potential for exposure to constituents from benzene soluble aerosols will also be monitored by sampling for selected PNAs (Polynuclear Aromatics). Industrial Hygiene sampling and analytical methods are included as Appendix 5. B. SAMPLING STRATEGY PLAN Major emphasis will be placed on increasing the sampling frequency of both personnel and area monitoring during 1988. To help insure meeting this important goal, an Environmental Assistant has been named at LGTI, with responsibility for coordinating the effort. 1. HYDROGEN SULFIDE AND CARBON MONOXIDE Current area and personnel monitoring for access to process area potentially containing H2S and CO will continue. During various plant conditions, such as startup, operation, shutdown, and maintenance, monitoring of personnel of all classifications will be documented to indicate actual exposure levels. 2. NOISE Personnel of all classifications will be monitored for noise exposure during 1988. In addition, annual area noise surveys will begin in 1988. 3. BENZENE SOLUBLE ORGANICS Monitoring for benzene soluble organics begun in 1987, will increase and continue during 1988. The 1988 program will include GC/MS scans for specific polynuclear aromatics. Surface wipes will be utilized to determine whether or not organic compounds are being carried from the process area to the control stations or other buildings.

Goal: Update Inventories on an annual basis. Accomplishment: Ordered, received and made fully operational area, personal, and portable Industrial Hygiene monitoring equipment associated with detection of noise, organics, dust, CO and H2S. Goal: Review effectiveness of monitoring equipment on an annual basis. Accomplishment: Began actual Industrial Hygiene monitoring of personnel and areas during start-up and initial operation of LGTI. Named Environmental Assistant to coordinate Industrial Hygiene Program. Goal: Increase monitoring effort, improved documentation and reporting procedures. Accomplishment: Area audits were performed during all phases of the LGTI start-up in an effort to verify the placement of the area monitors and requirements for personal and portable monitors for entry, and to aid in establishing areas with the highest potential for fugitive emissions. As a result of the audits, problems with the release of dissolved gases from the recycle water tanks in the process area were discovered, and the vent systems were successfully modified. Goal: Continue with area audits on a quarterly basis. DO 099958 confidential LGTI SURVEY, 1987 Page 6 V. EDUCATION AND TRAINING PROGRAMS A. HAZARD COMMUNICATION TRAINING On an annual basis, permanent employees are trained on the hazardous properties of the chemicals they work with or could be exposed to and are allowed access to written information about the chemicals especially as contained in the Material Safety Data Sheets. Also incorporated into this session is information on the consequences of overexposure to these chemicals and reactive chemical considerations associated with the process. Temporary contract personnel assigned to the block are trained via a Contractor Block Indoctrination Film. Additional training is administered as appropriate on the handling and disposal of asbestos and the proper use of CO and H2S monitors. B. RESPIRATOR PROGRAM The effectiveness of the respirator program at LGTI is audited quarterly, with semi-annual cartridge changeouts, and annual training on the proper use and care of the respirators. C. HEARING PROTECTION PROGRAM Ear protection requirements at LGTI are reviewed via annual training sessions typically incorporated into the monthly safety meetings. DO 099959 CONFIDENTIAL LGTI SURVEY, 1987 Page 7 VI. PLANT DESCRIPTION A. PROJECT OVERVIEW AND LOCATION The Dow Syngas Project produces medium BTU synthetic gas (syngas) for consumption by the existing gas turbine power generation units at Dow's Louisiana Division chemical complex in Plaqueraine, Louisiana. Figure 3 shows the location of the Louisiana Division. Figure 4 shows the location of the Dow Syngas Project facilities at the Louisiana Division site. At capacity, the Dow Syngas Project will produce 30,000MM BTU of synthetic gas per day from approximately 2,200 tons per day of western sub-bituminous coal from the Powder River Basin in Wyoming. The design-basis coal, used for purposes of sizing equipment, is a lignite coal. The Project will use sub-bituminous coal initially and intends to switch to lignite or other types of coal later on in the project life. All ranges of coal, including anthracite, bituminous, sub-bituminous, and lignite, may be used if the specific plant design is adapted to that coal type and as long as the feedstock does not exceed 1.2% sulfur as allowed in the air permit for the project. B. PROCESS DESCRIPTION The block diagram in Figure 5 illustrates the process used by the Dow Syngas Project. The following subsections describe various portions of the project. COAL SLURRY FACILITY The existing coal slurry facility, which was designed to support the Prototype II coal gasification plant, was expanded to provide the coal slurry feed for the commercial facilities. Coal is delivered in bottom dump hopper cars and discharged from the railcars into unload pit hoppers. Conveyors move the coal from the hoppers to a radial stacker which distributes coal over the entire stockpile area and keeps dust emission to a minimum. Reclaiming of the coal from the stockpile is accomplished by using a bulldozer to feed the coal in to reclaim pit hoppers where it is then ground and slurried with recycled process water and transferred to storage tanks. Coal slurry is transferred to the process site via pipeline into a storage tank located at the process site. DO 099960 CONFIDENTIAL LGTI SURVEY, 1987 Page 8 GASIFICATION, PRIMARY PARTICULATE RECYCLE, AND HEAT RECOVERY The Dow Syngas Project gasifier design is proprietary, but can be generally classified as a high-temperature, entrained-flow, slagging design. The coal slurry is fed to the reactor, where it is mixed with oxygen and the reactor temperature is carefully controlled to maintain a specific narrow range. The coal is almost totally gasified by partial combustion to produce synthetic gas consisting principally of hydrogen, carbon monoxide, carbon dioxide, and water. The sulfur in the coal is converted almost totally to hydrogen sulfide with small amounts of carbonyl sulfide. The nitrogen from the coal is converted primarily to elemental nitrogen with some ammonia found and to a lesser degree to hydrogen cyanide and thiocyanate. The ash is fused in the flame and is drained as molten slag from the bottom of the reactor by an enclosed system. The slag will be used for commercial purposes, rather than being disposed of as a solid waste. The gas is passed through a cyclone separator to remove most of the entrained char. The removed char particles are slurried with recycled water and the slurry recycled back to the gasifier. The raw synthetic gas containing some entrained particulates (char) is then cooled in a heat recovery train, generating steam. SECONDARY PARTICULATE RECYCLE AND COOLING The syngas passes from the heat recovery train to a wet particulate scrubber and the resulting slurry produced is pumped back to the gasifier. Thus, none of the particulate matter or scrubber water is discharged as waste streams. The scrubber product gas is then cooled through a series of heat exchangers before entering the H2S removal process. Water condensed from the product gas as it is cooled (sour condensate water) is stripped of the sour gases and much of the water recycled back to the process. Any excess water that has been stripped (sweet condensate water) will be discharged to the Division canal. SELECTAMINE H2S REMOVAL, SELECTOX SULFUR RECOVERY, AND TAIL GAS INCINERATION The sulfur in the sour syngas is removed by the Selectamine or GAS/SPEC ST-1 acid gas removal (AGR) process, which is a process licensed from the Dow Chemical Company. The sweetened product gas is suitable as fuel for the gas turbine power generation system, and the extracted acid gas is suitable as feed to the sulfur recovery unit. DO 099961 CONFIDENTIAL LGTI SURVEY, 1987 Page 9 Selectox sulfur recovery process is licensed through the Ralph M. Parsons Company, and the liquid sulfur produced by the Selectox process will be sold as a by product. The tail gas from the Selectox unit is fed to an incinerator which oxidizes the remaining H2S to S02 and vents it to the atmosphere. Small amounts of acid gas collected from various other points in the process are also disposed through the incinerator. EXISTING GAS TURBINES The clean syngas stream from the AGR is used to fire the equivalent of one existing gas turbine in the Power II facility at Dow's Louisiana Division. Two gas turbines are expected to be able to switch from natural gas to syngas as well as operate on blends of syngas and natural gas. EMERGENCY FLARE SYSTEM The location of the flare stack is in an area dedicated for that purpose. Adequate area has been left unoccupied to avoid any hazards when flaring. PROCESS WASTEWATER TREATMENT The water condensed from the product gas as it is cooled is passed through a water treatment system for removal of dissolved gases, primarily H2S and NH3. Much of the condensate from the water treatment system will be recycled to the coal slurry process. Any excess water (90 - 225 gpm; 175-225 gpm for lignite and 90-140 gpm for western subbituminous coal) that is not recycled to the process will be discharged to the Louisiana Division canal through a permitted outfall. The sweet condensate water will be characterized for contaminants that it may contain. If the level of contaminants are above the permitted level for discharge, the excess sweet condensate water will undergo secondary treatment for the removal of the impurities before being discharged. The secondary treatment will consist of treatment by activated sludge in the existing Louisiana Division wastewater treatment facilities. DO 099962 CONFIDENTIAL LGTI SURVEY, 1987 Page 10 INDUSTRIAL SOLID WASTE LANDFILL The spent catalysts which are periodically removed from the Selectox sulfur recovery unit will be landfilled. These are the primary solid wastes from the Dow Syngas Project that will be disposed of in landfills. The gasifier slag and liquid sulfur from the Selectox unit will be sold. The spent Claus catalyst will be landfilled in the solid waste landfill permitted for the Louisiana Division of the Dow Chemical Company. Spent Selectox catalyst is considered hazardous since it contains vanadium pentoxide, an acutely toxic chemical. It will be disposed in the hazardous waste landfill located within the Louisiana Division. DO 099963 CONFIDENTIAL LGTI SURVEY, 1987 Page 11 VII.

Environmental Monitoring Reference Manual for Synthetic Fuels Facilities, EPA-600/8-83-027. GENERAL DESCRIPTION: . Gas chromatography with flame ionization detection can be used to detect virtually any organic species which can be chromatographed. This technique Is applicable to gas samples collected on sorbents or in impinger solu tions, as well as aqueous and solid samples. The sample or sample extract is introduced into the gas chromatograph by either direct injection or thermal desorption. Separation of the sample components is achieved through use of a chromatographic column." A variety of. columns are available and the column used is dependent on the separation needed. Both capillary and packed columns can be used. This technique can be used to determine if any organic species are present, to obtain an estimation of the total chromatographable organic loading, and/or to determine the pre sence or concentration of selected compounds by comparison to analytical standards. METHODS: Pre-Analysis Preparation: The sample Is Introduced by thermal desorption or as an extract by direct injection. Procedures such as column separation, derivatiza-- tion, or solvent partitioning are used particularly for complex samples as they provide for more reliable identification and quantification of species present. Sample Analysis: Direct Injection or thermal desorption gas chromatography with flame ionization detection can be used in determining the presence of almost any organic species which can be chromatographed. GC conditions are determined from the analysis of calibration standards containing the analytes of interest. The method is not specific for any compound.

The analytes of Interest must be chromatographable. High concentrations of other organics can intefere with the analysis. The detector stability and linearity is established and verified proior to sample analysis. Identification Is based on retention time only. This method cannot be used to unequivo cally Identify unknowns or provide any specific information about the unknown except estimated boiling points. This method is tentative and must be validated for each sample or matrix on which it is used. During this process it may be determined that changes in reagents, equipment or procedures must be"made.

GENERAL DESCRIPTION: The instrument is non-specific, sensitive to detect less than 0.2 ppm of many organics. It ib a photoionization analyzer, light weight and operates on rechargeable batteries. The sensor consists of a sealed ultraviolet light source that emits photons which ionize many trace organics but not the components of air (O2, N2, CO, CO2, or H2O). METHODS; Pre-Analysis Preparation: Battery check and calibration with a standard gas in air is conducted. Sample Analysis: No preparation necessary. The sensor is non-specific, so only a single material can be measured as a gas in air. QA/QC: Standard calibration methods before and after sampling. Use G.C. to confirm that a single gas is present.

PROCEDURES REFERENCE; Teledyne Analytical Instruments, Model 600 UV/Visible Photometric Analyzer, 19S3. GENERAL DESCRIPTION: An on--stream analyzer will automatically and continuously sample the pro cess stream. Hydrogen sulfide or sulfur dioxide will be measured by uti lizing infrared or ultraviolet absorption techniques. METHODS: Pre-Analvsis Preparation: Sample stream to analyzer will be routed through a sample system designed to remove particulate matter. This will be done by selective filtration. Sample Analysis: The sample stream will flow through a sample cell which is in an opti cal path consisting of a source lamp, the cell, and a detector. Sample flows continuously through the cell and absorbs optical energy at various wave lengths in accordance with its composition. The con centration of the absorbing compound is proportional to the logarithm of the energy entering the sample divided by the transmitted energy, and inversely proportional to the cell path length. QA/QC: The detector response will be checked by flowing a non-absorbing gas through the sample cell and calibrating the instrument to read 100Z, then flowing a known concentration of gas through the sample cell and calibrating the instrument to read that concentration.

The survey included reviewing building specifications to identify potential problem areas and a walk-through visual inspection of areas likely to have asbestos-containing materials such as motor control centers and lab rooms. The building specifications indicated the following: 1. Asbestos vinyl floor tile (Block 57 and Block 70) Sec. 9.5.3.1. No other specific references to asbestos were found. Other areas visually inspected: Building Comments Lab None found Women's Locker Room None found Motor Control Center Transite electrical insulation between the boxes Our recommendations are as follows: 1. The motor control center has transite (asbestos-containing material) as electrical insulation between the boxes. This transite is in good condition; no remedial action is required. 2. Asbestos-containing materials (transite, gaskets) must be main tained, handled properly, and personnel trained according to the Louisiana Division Asbestos Guidelines. 3. A permanent file should be maintain d identifying asbestos loca tion, maintenance, and training records. AN OPERATING UNIT OP THE D W CHEMICAL COMPANY DO 100017 CONFIDENTIAL 4, The results of this survey identify the location of asbestoscontaining materials in the LGTI Plant's permanent buildings; however, caution is advised during the demolition of any building materials (i.e. flooring, insulation). 5. If further information, sampling, or material identification are required, please contact Industrial Hygiene (Ext. 6163) or Maintenance (Ext. 6443, or Radio 640).
