It contains specific reference information on the major chemicals made or used at Vista*s plants, along with approved responses to questions that would likely be encountered during press interviews. This updated and expanded statement supersedes the material included in the earlier **If--Needed document on Air Emis sions,11 dated Feb. 28, 1986. Please destroy all copies of that document and replace them with the present statement. Please note that while the actual and permitted emission totals included in this statement are correct as shown, a few of the numbers have "caveats** associated with them--for example, some of the some of the permitted plant emissions are for "new equipment** only. In keeping with the general nature of this document, however, we have chosen not to in clude this kind of detailed information because it might only cloud the issue for the press. If you have any questions regarding the attached material or need assistance in responding to a media inquiry, please let me know. Please also continue to keep me advised of all lo cal press calls or contacts. Thanks for your help. ccs REL, RTF, JAD, TGG, WLM, DAK, MSR, JCB, DLM VHR 5174 if-Needed Statement AIR EMISSIONS All Vista plant locations Date approved for use: September 18, 1986 Use the following material only in response to specific questions from the media: Does Vista use or manufacture hazardous chemicals? Vista Chemical uses and manufactures a number of chemicals in volumes large enough to be of concern in the event of an emergency. However, these chemicals are strictly controlled and monitored. Our plants have been carefully designed and built to handle them safely. Our employees who work with these chemicals have received detailed special training. All of these precautions make an accident which could injure a member of the public extremely unlikely. Do you routinely release any of these chemicals to the atmosphere? Yes. Air emissions from our manufacturing processes are regulated by state and federal environmental agencies. These agencies have issued permits to Vista regulating our air emissions. Vista currently operates under 43 different environmental permits which specify allowable air emissions for chemicals ranging from sulfur dioxide and nitrogen oxide, which come from fuel burning processes such as steam generation, to hydrocarbon products. In addition, two compounds produced and used extensively by Vista--benzene and vinyl chloride monomer--are stringently regulated under the Clean Air Act as hazardous air pollutants. The amount ofpermitted emissions is generally determined by health effects data and by best available control technologies for our manufacturing processes. How can you justify releasing these hazardous chemicals, some of which are known cancer-causers, into the atmosphere on a routine basis? Vista Chemical and the regulating agencies believe that the permitted quantities will not harm the employees who work in our plants or members of the public and the environment nearby. The chemicals we use, manufacture or which come from our fuel-burning processes are well understood, common chemicals which have been used for years throughout A VHR 5175 Air Emissions Page 2 * the industry and which have been studied at length. The effects ofexposure to them are well known. Safety and health precautions for properly handling them have been developed, installed and regularly tested at our plants. Our plants* emissions are controlled so that the concentration ofcancer-suspect chemicals in the air in the plants is as low as feasible, typically less than one part per million. With those concentrations in our plants, we know that concentrations in the air further away from our plants are even lower. Chemicals which have been shown to cause cancer have done so only at relatively high concentrations over long periods of time. Based on the large amount of scientific data available from studies done over the past two decades, low level or short term exposure to these chemicals does not create a hazard. We believe there is a more than adequate margin of safety for our employees and the public. The amounts of these chemicals routinely released have been greatly reduced over the years, because it makes good business sense and because ofmore rigorous governmental regulations. We've spent more than $3.2 million in the past five years just to protect the air around all our plants. Why is it necessary to release chemicals to the atmosphere? Why don't you just make your plants leak-proof? It's not possible to make a chemical plant 100 percent leak-proof, or to burn fuel without emitting some pollutants. We employ the best available technology and operating procedures to keep emissions at very low levels which are safe for employees and the neighbors ofour plants. Besides the routine emissions to the atmosphere, do you have accidental releases? Very infrequently. We must immediately report these releases in accordance with the appropriate state or federal regulations. No accidental release of a chemical from a Vista Chemical plant has ever caused a death or serious injury to a member of the public. We've studied the causes of these releases and have made engineering or operational changes to prevent their recurrence. UHR 51?^ Air Emissions Page 3 * \ Why haven't you reported these releases to people in the communities surrounding your plants? Because the releases have not been of a quantity which would cause injury to the public, and an evacuation of the community has never been required as a result of the releases. Could such an accidental release lead to a Bhopal-type accident at one of your plants? Because the chemicals we handle are not as toxic as methyl isocyanate (MIC), and because of the strict controls and procedures we use in our manufacturing processes, we believe that that the possibility of an incident similar to that which happened in Bhopal is very remote. Our plants are well designed and are maintained, inspected and operated by well trained, experienced personnel. In the event of a large gas release, a catastrophic loss of life (such as occurred in Bhopal) is highly unlikely because we do not have any materials as toxic as methyl isocyanate. In addition, we have emergency procedures for dealing with gas leaks ifone were to occur and we are working with local authorities to improve procedures for protecting the public in the event of an emergency. Have you made any changes as a result of Bhopal? Due to the extent of the tragedy at Bhopal, we instituted a formal program to reassess our existing safety systems and emergency procedures. This assessment included a study ofmaterials present in the plant, our handling, processing and storage of those materials, employee training and emergency response procedures. We wanted to be certain that we are operating our plants in a manner that is safe and which will prevent any tragedy from occurring in our plant communities. We've also broadened our studies to include the surrounding communities. Our work at our Lake Charles plants is a good example. We have joined together with other local industry members as well as medical, governmental, police and fire agencies in a committee to improve our communication and understanding. That committee is examining such topics as availability of emergency medical care, a direct public warning system and evacuation routes which might be needed in the unlikely event of a major catastrophe. VHR 517? Air Emissions Page 4 What sort of warning system or evacuation procedure do you have for the public? Current procedures call for alerting and providing assistance to local authorities who have the authority to handle evacuation in the event of a disaster. At our Lake Charles complex, we are connected by special phone lines with other major plants and governmental agencies in the area, so that we can warn or be warned of emergencies. More direct methods of notifying people in the surround communities are being studied. Which chemicals listed by the EPA, or otherwise classified as acutely toxic, does Vista Chemical use or manufacture? 1. Chlorine is used as a feedstock at our Lake Charles VCM Plant and the Baltimore LAB (linear alkylbenzene) Plant. 2. Ethylene oxide is used as a feedstock at our Lake Charles Chemical Plant 3. Hydrogen fluoride is used as a catalyst at our Lake Charles LAB Plant 4. Sulfur trioxide is used as a feedstock at our Hammond Premium Sulfonation Plant. 5. Hydrogen chloride is used as a feedstock at our Lake Charles Chemical Plant and at our Lake Charles VCM (vinyl chloride monomer) Plant. Muriatic acid, its liquid form, is manufactured at our Baltimore LAB Plant; a small amount is also produced in our VCM Plant incinerator unit. In addition, we use or manufacture much smaller quantities of: 1. Sulfur dioxide 2. Nitric acid 3. Sulfuric acid 4. Isopropanol (isopropyl alcohol) 5. Methanol (methyl alcohol) [See reference section for more detail.] Which of the chemicals you use or manufacture are volatile organic compounds? 1. Ethylene dichloride (EDC) and 2.

Xylene 4. Chloroform 5. Isopropanol (isopropyl alcohol) [See reference section for more detail.] What do you do about tiny leaks, ones that are so small that even people working in the plant would not notice? We have a system of fixed point monitors in our plants to detect quantities of the of the most hazardous VOCs in the air as small as one part per million, or less. When these chemicals are detected, an operator is notified. Then, employees using portable detection equipment can pinpoint the leak and repair it. What chemicals are produced by yourfuel-burning processes? 1. Particulates are emitted at all of our plants, except Hammond. 2. Sulfur oxides (SOx) is emitted by all ofour plants. 3. Nitrogen oxide (NOx) is emitted by all of our plants, except Hammond; 4. Carbon monoxide is emitted by all of our plants, except Hammond.

Chlorine Plant LCVCM Actual emissions (tons per year) '9.6 Permitted emissions (tons per year) Basis Chlorine is a major feedstock at our Lake Charles VCM Plant, arriving by pipeline or rail tank car. We use it to make vinyl chloride monomer, the major ingredient in polyvinyl chloride (PVC), a plastic with hundreds of uses from vinyl siding and food packaging to plastic pipe and record albums. Chlorine is also used as a feedstock at our Baltimore LAB (linear alkylbenzene) Plant to make a major ingredient in industrial and household cleaning products, such as detergents. Its most common usage is in water treatment plants. Chlorine is a heavy, greenish-yellow gas at normal temperatures and has a pungent, irritating odor which is detectable at very low levels. Because it is intensely irritating, you would not remain voluntarily in dangerous concentrations. Exposure to high concentrations can damage tissues in the respiratory system resulting in breathing difficulties. Severe exposures could be fatal. Chlorine is also present at most of our other plants in cylinder quantities for water treatment purposes. E PA 402 Hydrogen fluoride (HF) Plant Actual emissions (tons per year) LCLAB 0 Permitted emissions (tons per year) Basis 0- Hydrogen fluoride is used as a catalyst at our Lake Charles LAB Plant. It arrives at the plant by truck. We use it to make the chief active ingredient in such products as laundry detergents and dishwashing liquids. It is a colorless fuming liquid which rapidly vaporizes in the atmosphere to a gas, which reacts with moisture in the air to form a visible cloud. HF is very irritating to the skin, eyes and respiratory tract at low concentrations. Exposure to high concentration in air can burn the skin and damage lung tissue. Lung damage resulting from severe exposures could be fatal. EPA 402 A VHR 5184 VOC = volatile organic compound.

EPA 402 Ethylene Oxide (EO) Plant Actual emissions (tons per year) LCCP 4 Permitted emissions (tons per year) Basis Ethylene oxide is a feedstock in the ethoxylation unit at the Lake Charles Chemical Plant. We use it to make ingredients which have a multitude of uses, including cleaning and personal care products. It is shipped to our plant by rail tank car. Ethylene oxide is a highly flammable and reactive gas at room temperature. We handle it under pressure in a liquid form. At high concentrations, it has an ether like pungent odor and is irritating to the eyes, nose and throat. Exposure to extremely high concentrations may result in lung injury and accumulation of fluid in the lungs and death. It is regulated as a cancer-causing agent. This chemical is highly volatile and disperses rapidly in the atmosphere to low concentrations. Therefore, it is unlikely that hazardous concentrations would be encountered outside the plant boundaries. EPA 402, VOC A VHR 5185 VOC = volatile organic compound.

VCM is shipped from Lake Charles and arrives at Aberdeen and Oklahoma City by rail tank car. We use it to make polyvinyl chloride (PVC), a plastic with hundreds of uses from vinyl siding and food packaging to plastic pipe and record albums. Vinyl chloride monomer (VCM) is a colorless gas and a liquid under pressure. Vapors can form flammable mixtures in air. Burning VCM generates hydrogen chloride (HC1), a strongly irritating gas which, in high concentrations, can damage tissues in the respiratory system. High levels of exposure to VCM over long periods of time can cause cancer in humans. VCM is highly volatile and disperses rapidly in the atmosphere to low concentrations. Therefore, it is unlikely that hazardous concentrations would be encountered outside the plant boundaries.
