The following items need some follow up attention. 1. We need a copy of your revised site map as soon as possible. 2. The method of restraint for the 150# chlorine cylinder was insufficient. Compressed gas cylinders must be restrained around the body of the cylinder. Never attach restraints around the valve or neck of a cylinder. The restraint must be attached to a sturdy support. The chlorine cylinder at Gist was attached to what appeared to be a rather wobbly electrical conduit. As we discussed, this situation needs to be corrected immediately. 3. Several of the drum chemicals had inadequate labels. For instance the 40% sulfuriC acid - 15% phosphoric acid had a hand written, almost illegible label. Container labeling must clearly state the hazardous ingredients or display the National Fire Protection Association (NFPA) hazard ratings. I have attached the NFPA classification definitions and placarding standard for your use. 4. Several of the haz mat storage tanks bear only small labels that are placed Iow and are impossible to see from a distance. Labeling on tanks needs to be large and visible from a distance for purposes of hazard assessment during a fire or haz mat incident. The Fire Department does require the use of the NFPA hazard identification diamond on all hazardous material above ground storage tanks. 5. Section 80.401 (c)2B of the Uniform Fire Code requires emergency shutoff valves to be identified and the location to be clearly visible and indicated by raeans of a sign. We particularly wish to see the shutoff valves in the systems handling acutely hazardous materials marked per the UFC requirement. 6. Due to the fact that the generation of hydrogen is possible in the event of a sulfuric acid spill, we request that your emergency planning include provisions to extinguish ignition sources on the exterior deck if a sulfuric acid spill occurs. We understand that it is not likely that hydrogen would be able to accumulate in this area. However, hydrogen has a very broad explosive range, and our ability to monitor for the lower explosive limit would be inhibited by the corrosive nature of the acid vapors. Corrosive environments will quickly burn out our detection equipment. We especially appreciate your efforts toward labeling the tanks that contain only molasses and water. In an industrial setting, identification of non-hazardous materials is also very valuable to emergency responders. I have added the location of the lock box and weather station to your hazardous materials management plan. Please address the items.listed above as soon as possible. I will contact you with in the next month to follow up on the resolution of these items. Thanks again for all of your cooperation.

GENERAL DESCRIPTION OF FACILITY Gist-brocades Food Ingredients Inc.'s Bakersfield plant produces baker's yeast. The yeast is grown in a batch process in fermentation tanks. During this batch process, the yeast solution is fertilized in the fermentation tanks with phosphoric ~ a~sulfuric acid and ammonium hydroxide. After the fermentation process is c~)~ C~mplete, the yeast is dried and/or packaged for the industrial market. B. DESCRIPTION OF SULFURIC ACID PROCESS AND EQUIPMENT The sulfuric acid system has been maintained in excellent condition since it began service in 1985. The system consists of a 700 gallon storage tank, a 20 gallon dosing tank, and associated transfer and distribution piping as shown in Figure 1. Material of construction for the sulfuric acid system is 316L stainless steel. All tanks and pipelines are welded. The 700 gallon storage tank is an atmospheric pressure tank. The dosing tank is a pressure vessel that is equipped with a pressure relief valve set at 35 psig. This pressure relief valve relieves back to the acid storage tank. Sulfuric acid is delivered to the storage tank by the vendor using a pneumatically driven diaphragm type pump. After the delivery is complete, the acid remaining in the fill line is blown into the storage tank using compressed air from the plant air system. The storage tank overflow line is piped directly to the plant wastewater system. Since the yeast production process is a batch process, sulfuric acid is added to the yeast solution in a batch process. To accomplish this, sulfuric acid is gravity fed from 'the storage tank to the dosing tank when needed. Once the dosing tank is isolated (valved out) from the storage tank, compressed air from the plant air system is used to force the acid from the dosing tank into the acid distribution piping.--The dosing tank is normally empty and is filled only when sulfuric acid is to be fed to the fermenters or the yeast storage tanks. Phosphoric acid is also used dUring the yeast production process. Normally, the phosphoric acid is delivered to the process through its own distribution piping. Gist-brocades/Sulfuric Acid/RMPP Page2 Luft Environmental Consulting ~ . STOOGE However, phosphoric acid can be delivered to the sulfuric acid dosing tank for distribution to the fermenters or the yeast storage tanks. Phosphoric acid (37%) and sulfuric acid (93%) are compatible compounds. A minor amount of heat may be generated if the two acids are mixed due to the relative strengths (water content) of the acids. C. ACCIDENT HISTORY Gist-brocades Food Ingredients Inc. has not had an accident involving sulfuric acid at the Bakersfield Plant within the last three years. D. RECORDKEEPING PROCEDURES The sulfuric acid storage tank level is checked once per week at a minimum 'Written weekly and monthly inventories are kept that include a record of the storage tank level. An order for sulfuric acid is placed when the inventory indicates that the tank level is below the reorder point. All documents relating to the RMPP are maintained for a minimum of five years. E. PERSONNEL AND TRAINING All operations personnel are specifically trained for their responsibilities within the plant. In addition to the equipment training, the operations personnel receive training in fire prevention, fire control, accident prevention, and safety and first aid, in accordance with Gist-brocades Food Ingredients Inc. standards. All personnel at the plant are instructed in the site specific environmental and safety requirements on a periodic basis. The general subject matter for this training inciudes the following elements: * Hazardous materials handling * Hazard communication program * . Emergency response and evacuation procedures Annual safety training includes first aid procedures for individuals exposed to acids used at the facility. Emergency evacuation routes and the locations of possible hazards are included in the safety program. Gist-brocades/Sulfuric Acid/RMPP Page3 Luff Environmental Consulting The Plant Manager and Maintenance Engineer are responsible for the implementation of the RMPP and for the training of the Gist-brocades Food Ingredients Inc. employees. F. EMERGENCY RESPONSE PROCEDURES In the event of a large volume acid spill, the acid would be allowed to drain into the wastewater system. Depending on the nature of the spill, plant personnel may don the appropriate personnel protective equipment and attempt to stop the spill. A large volume spill would be permitted to drain into the wastewater system. Following the acid spill, plant personnel would wash any residual acid into the wastewater system using copious amounts of water. G. HAZARD ANALYSIS The HazOp study generated release events for the sulfuric acid system based on the design of the system, potential operator error, and external events, such as an earthquake. The HazOp study indicated that the possible release events were a hose failure during acid delivery and a tank or pipeline failure as the result of an earthquake. These release events were reviewed to determine whether there was a high likelihood of occurrence or a significant consequence if the release were to occur. None of the release events had a high probability of occurrence. The worst credible release would involve a large volume acid spill onto the concrete and into the wastewater system. The maximum volume of acid that could be released from the sulfuric acid system is 700 gallons from the storage tank. Due to the Iow vapor pressure of sulfuric acid, a significant airborne release from a spill of the acid is very unlikely. 1. ACID SPILL ON CONCRETE The worst case release from the sulfuric acid system involves an external event, such as an earthquake, that causes a catastrophic failure of the main sulfuric acid storage tank. If the release were to occur shortly after an acid delivery,-a maximum of 700 gallons of sulfuric acid could be released. The area around the acid storage tank is sloped so that any liquid spill would flow toward a storm drain and into the wastewater system. The sulfuric acid storage tank is mounted on a concrete pad, and is surrounded by concrete and rubber coated concrete. Gist-brocades/Sulfuric Acid/RMPP Page4 Luft Environmental Consulting In the event of a release, the acid would move in a fairly narrow stream toward the storm drain and would react with any concrete in its path. This chemical reaction would release hydrogen gas. In order to ignite the hydrogen, the hydrogen concentration in the air at the combustion source would have to exceed the lower explosive limit (LEL) of 4% (40,000 ppm). Discussion with a sulfuric acid manufacturer1 indicates that the rate of evolution of hydrogen is not expected to be sufficient to support combustion. Since the combustion sources are located approximately 80 feet from the acid tank and the acid spill would flow away from the combustion sources due to drainage grading, an explosion and/or fire is very unlikely. Additionally, there are no confined spaces above the sulfuric acid system to trap the hydrogen gas. In this release event, it is possible that employees would exit the building on the south side through a door located near the sulfuric acid storage tank. These workers could be inadvertently exposed to the acid as it drained from the tank to the wastewater system. Injury could result from individuals walking through the acid by splashing the acid on clothing and exposed areas of skin. However, there are emergency eyewash/shower stations located near the acid storage tank and the acid fill connections. Use of (hese emergency eyewash/shower stations would minimize the injuries to exposed workers. 2. ACID SPILL IN WATER Sulfuric acid could be released to the wastewater system as a result of a catastrophic failure of the storage tank or as the result of overfilling the storage tank. The compartmentalized vendor trucks carry a maximum of 650 gallons of sulfuric acid. Based on normal reorder quantities, overfilling the storage tank could release a maximum of 60 gallons of acid to the wastewater system. A catastrophic failure of the storage tank could release 700 gallons of acid to the wastewater system. Since the mixing of sulfuric acid and water produces heat, the possibility of an offsite consequence if the acid enters the wastewater system was investigated. If an acid spill reached the wastewater system, the acid would react with the water in the wastewater system. This reaction would evolve heat. Temperatures in excess of 400° F could be obtained depending on the rate 1jerry Mitchell, Cargill Inc., Telephone communication on December 17, '1992. Gist-brocades/Sulfuric Acid/RMPP Page5 Luff Environmental Consulting the acid is added to the water and the relative amounts of water and acid that are present.2 Engineering calculations also indicate that temperatures above 325° F (163° C) are possible as shown in Figure 2. Since the wastewater system contains a minimum of 5,600 gallons of water at all times, the highest ratio of acid to water is 0.13 which corresponds to a temperature of approximately 125° F, as shown in the figure. At that temperature, no steam or acid mists are expected to form. Also, the vapor pressure of a 93% sulfuric acid solution is relatively Iow, even at elevated temperatures (see Attachment 1)3. If sulfuric acid (100%) is heated to temperatures above 572° F (300° C), it begins to decompose and release sulfur oxides. Further heating and higher temperatures accelerate the decomposition process. As stated above, the acid used at the Gist-brocaQes iacility is a 93% solution. The reduced conCentration of sulfuric acid lowers the vapor pressure of the sulfur oxides substantially. The reduced vapor pressure substantially raises the temperature required for the evolution of sulfur oxides from the acid. Since there are no combustible materials present near the storage tank, heating of the tank due to a nearby fire is extremely unlikely. It is, therefore, unlikely that the storage tank could be heated sufficiently to cause decomposition of the acid. H. OFFSITE CONSEQUENCE ANALYSIS The hazard analysis indicated that a worst case release of sulfuric acid could release 700 gallons of sulfuric acid to the wastewater system. Large volumes of water are contained in the wastewater system, so the heat produced by this reaction would not be sufficient to cause decomposition of the acid or produce steam that could carry sulfuric acid into the air. Since the sulfuric acid would not be carried offsite, no offsite consequences are expected. Emergency eyewash/shower stations are available for onsite personnel who may be exposed to the acid. 2jerry Mitchell, Cargill Inc., Telephone communication on December 17, 1992. 3perry's Chemical Engineer's Handbook, 6th ed., McGraw-Hill Book Company, New York, NY 1984 Gist-brocades/Sulfuric Acid/RMPP Page 6 Luft Environmental Consulting TEMPERATURE OF SULFURIC ACID ADDED TO WATER 35O 300 '-' 250 D 200 ,,, 150 ,,, 100 0 I i I I I I I I I J I I I I I I ; I I ~- I I I I I I I I I 0 1 2 3 4 5 6 RATIO OF ACID TO WATER Gist-brocades/Sulfuric Acid RMPP Figure 2 Luft Environmental Consulting GIST-BROCADES FOOD INGREDIENTS, INC.-SULFURIC ACID HAZOP REVIEW SUMMARY Item # H2SO4 Equip. .~uide Wor~ Deviation Poss~le Cause Probability Severity Consequence Comments 1 Fill No No Row Fill valve dosed or blocked.

Berkeley RESPONSES TO ITEMS #4 AND #6 OF THE BAKERSFIELD CITY FIRE DEPARTMENT'S CONCERNS DATED JANUARY 25, 1993 · Individuals at the plant participate in annual training concerning evacuation of the plant during an emergency. The locations of various hazards, including the sulfuric acid tank, are addressed during the training sessions. Several alternate routes are available for employees exiting the building during an emergency. Since the existing training program includes alternate escape routes, additional training will not be required. · Several acids are used at the Gist-brocades plant site. Periodic safety training includes the safe handling of acids, personnel protective equipment, and the use of safety showers that would be used in the event that an individual is exposed to an acid, including sulfuric acid. · Mixing of sulfuric acid and water results in the evolution of heat. The resulting temperatures are not high enough to cause sulfur oxides to be emitted. Figure 2 in the enclosed RMPP addendum shows the maximum temperature is expected to be slightly higher than 325° F at a ratio of 1.8:1, well below 572° F where decomposition of the acid begins to occur. · In the event of a sulfuric acid spill, Gist-brocades personnel are trained to secure the area and notify their supervisor. The spill would be evaluated and the appropriate public emergency response agency would be notified if required. The best course'of action for mitigation and clean up would be determined before Gist-brocades personnel attempt mitigation or clean up procedures. · Written operating procedures for the sulfuric acid system have been developed and implemented as recommended.

As we discussed, it would be helpful if you noted in the,text of the hazard analysis the potential volume of a delivery truck release scenario. Per your request, I have reviewed the Health and Safety Code'to determine what additional information will be needed to complete the RMPP. These items are listed below. ~1. Report of any accidents within the last three years relating to the sulfuric acid. v/~. Add the age and condition of'the equipment to the existing description of the process and equiPment. ,,/~. Record keeping procedures for verification of the acid reorder schedule should be included.. 4_,,/ Operator training is listed as a safeguard. Include a description of the training program for the operators. It was noted that evacuation routes cross areas that may be contaminated with acid Will additional training be required for general personnel so that they will know what to do if exposed to sulfuric acid during a release? Are there alternative evacuation routes that could be used if an acid spill occurs? It was noted that acid/Water mixing ratios of about 1 result in high temperatures that may cause the release of sulfur oxides. If the acid is allowed to flow into the drainage system and into the large tank, this problem is avoided. However, if operators wash down the plant deck,during a release the situation could worsen. Should operators be trained specifically about the possible effects of washing down a spill area? What are the operators expected-to do during an emergency release? 5.-''/''' Include a section formally titled Offsite Consequence Analysis and report the findings. 6../,/'' Include a schedule for'development of the recommended written operating procedures.

Luff Principal Mechanical Engineer cc: Bob Deedy, Gist-brocades Food Ingredients, Inc with enclosure Enclosures -- RTR LEC-93-0003 GIST-BROCADES FOOD INGREDIENTS, INC. HAZARD ANALYSIS - SULFURIC ACID SYSTEM A. GENERAL DESCRIPTION OF FACILITY Gist-brocades Food Ingredients Inc.'s Bakersfield plant produces baker's yeast. The yeast is grown in a batch process in fermentation tanks. During this batch process, the yeast solution is fertilized in the fermentation tanks with phosphoric acid, sulfuric acid and ammonium hydroxide. After the fermentation process is complete, the yeast is dried and/or packaged for the industrial market. B. DESCRIPTION OF SULFURIC ACID PROCESS AND EQUIPMENT The sulfuric acid system consists of a 700 gallon storage tank, a 20 gallon dosing tank, and associated transfer and distribution piping as shown in Figure 1. Material of construction for the sulfuric acid system is 316L stainless steel. All tanks and pipelines are welded.. The 700 gallon storage tank is an atmospheric pressure tank. The dosing tank is a pressure vessel that is equipped with a pressure relief valve set at 35 psig. This pressure relief valve relieves back to the acid storage tank. Sulfuric acid is delivered to the storage tank by the vendor using a pneumatically driven diaphragm type pump. After the delivery is complete, the acid remaining in the fill line is blown into the storage tank using compressed air from the plant air system. The storage tank overflow line is piped directly to the plant wastewater system. Since the yeast production process is a batch process, sulfuric acid is added to the yeast solution in a batch process. To accomplish this, sulfuric acid is gravity _. fed from the storage tank to the dosing tank when needed. -Once the dosing tank is isolated (valved out) from the storage tank, compressed air from the plant air system is used to force the acid from the dosing tank into the acid distribution piping. The dosing tank is normally empty and is filled only when sulfuric acid is to be fed to the fermenters or the yeast storage tanks. Phosphoric acid is also used during the yeast production process. Normally, the phosphoric acid is delivered to the process through its own distribution piping. However, phosphoric acid can be delivered to the sulfuric acid dosing tank for Gist-brocades/Sulfuric Acid/RMPP Page I Luft Environmental Consulting STORAGE F-t F-2 aA~: ~/ay/9~ n~ws~o SULFURIC ~CID distribution to the fermenters or the yeast storage tanks. Phosphoric acid (37%) and sulfuric acid (93%) are compatible compounds. A minor amount of heat may be generated if the two acids are mixed due to the relative strengths (water content) of the acids. C. HAZARD ANALYSIS The HazOp study generated release events for the sulfuric acid system based on the design of the system, potential operator error, and external events, such as an earthquake. The HazOp study indicated that the possible release events were a hose failure during acid delivery and a tank or pipeline failure as the result of an earthquake. These release events were reviewed to determine whether there · was a high likelihood of occurrence or a significant consequence if the release were to occur. None of the release events had a high probability of occurrence. The worst credible release would involve a large volume acid spill onto the concrete and into the wastewater system. The maximum volume of acid that could be released from the sulfuric acid system is 700 gallons from the storage tank. Due to the Iow vapor pressure of sulfuric acid, a significant airborne release from a spill of the acid is very unlikely, unless the acid adversely reacts with another compound. D. ACID SPILL ON CONCRETE The worst case release from the sulfuric acid system involves an external event, such as an earthquake, that causes a catastrophic failure of the main sulfuric acid storage tank. If the release were to occur shortly after an acid delivery, a maximum of 700 gallons of sulfuric acid could be released. The area around the acid storage tank is sloped so that any liquid spill would flow toward a storm drain and into the wastewater system. The sulfuric acid storage tank is mounted on a concrete pad, and is surrounded by.concrete and rubber coated concrete. In the event of a release, the acid would move in a fairly narrow stream toward the storm drain and would react with any concrete in its path. This chemical reaction would release hydrogen gas. Ir~ order to ignite the hydrogen, the hydrogen concentration in the air at the combustion source would have to exceed the lower explosive limit (LEL) of 4% (40,000 ppm). Discussion with a sulfuric acid manufacturer1 indicates that the rate of evolution of hydrogen is not expected to 1jerry Mitchell, Cargill Inc., Private communication on December 17, 1992. Gist-brocades/Sulfuric Acid/RMPP Page2 Luft Environmental Consulting be sufficient to support combustion. Since the combustion sources are located approximately 80 feet from the acid tank and the acid spill would flow away from the combustion sources due to drainage grading, an explosion and/or fire is very unlikely. Additionally, there are no confined spaces above the sulfuric acid system to trap the hydrogen gas. ~ In this release event, it is pOssible that employees would exit the building on the south side through a door located near the sulfuric acid storage tank. These workers could be inadvertently exposed to the acid as it drained from the tank to the wastewater system. Injury could result from individuals walking through the acid by splashing the acid on clothing and exposed areas of skin. However, the are emergency eyewash/shower stations located near the acid storage tank and the acid fill connections. Use of these emergency eyewash/shower stations would minimize the injuries to exposed workers. E. ACID SPILL IN WATER Sulfuric acid could be released to the wastewater system as a result of a catastrophic failure of the storage tank or as the result of ovedilling the storage tank. Based on normal reorder quantities, overfilling the storage tank would release a maximum of 60 gallons of acid to the wastewater system. A catastrophic failure of the storage tank could release 700 gallons of acid to the wastewater system. Since the mixing of sulfuric acid and water produces heat, the possibility of an offsite consequence if the acid enters the wastewater system was investigated. If an acid spill reached the wastewater system, the acid would react with the water in the wastewater system. This reaction would evolve heat. Temperatures of 400° F to 500° F could be obtained depending on the rate the acid is added to the water and the relative amounts of water and acid that are present.2 Engineering calculations also indicate that temperatures above 400° F (200° C) are possible as shown in Figure 2. Since the wastewater system contains a minimum of 5,600 gallons of water at all times, the highest ratio of acid to water is 0.13 which corresponds to a temperature of approximately 150° F, as shown in the figure. At that temperature, no steam or acid mists are expected to form. Also, the vapor pressure of a 93% sulfuric acid solution is relatively Iow, even at elevated temperatures (see attached table)3, 2jerry Mitchell, Cargill Inc., Private communication on December 17, 1992. 3perry's Chemical Engineer's Handbook, 6th ed., McGraw-Hill Book Company, New York, NY Gist-brocades/Sulfuric Acid/RMPP Page3 Luft Environmental Consulting If sulfuric acid (100%) is heated to temperatures above 572° F (300° C), it begins to decompose and release sulfur oxides. Further heating and higher temperatures accelerate the decomposition process. As stated above, the acid used at the Gist-brocades facility is a 93% solution. This reduced concentration lowers the vapor pressure of the sulfur oxides substantially. The reduced vapor pressure substantially raises the temperature required for the evolution of sulfur oxides from the acid. Since there are no combustible materials present near the storage tank, heating of the tank due to a nearby fire is extremely unlikely. It is, therefore, unlikely that the storage tank could be heated sufficiently to cause decomposition of the acid. F. SUMMARY The hazard analysis indicated that a worst case release of sulfuric acid could generate steam if the acid contacts a limited amount of water. The heat produced by this reaction would not be sufficient to cause decomposition of the acid. Any steam produced by the reaction could carry a sulfuric acid mist-into the air. However, since sulfuric acid is a heavy chemical and the steam would dissipate quickly, no offsite consequences am expected. Emergency eyewash/shower stations are available for onsite personnel who may be exposed to the acid. 1984 Gist-brocades/Sulfuric Acid/RMPP Page4 Luff Environmental Consulting TEMPERATURE (F) 3-68 PHYSICAL AND CHEMICAL DATA I TABLE 3-14b Sulfuric Acid Partial Pressure, bar, over Aqueous Sulfuric Acid' 50 513E - 07 .;~ 70 336E-06 80 .786E-06 100 371E-05 140 .50~E- 04 · 210 .159E--02 :., 220 .239E-02 i: 240 515£-02 : '250 .740E--02 280 .208E--01 i :~.
