Introduction
I The National Energy Policy Office (NEPO) of Thailand promulgated new clean fuels standards in late 1992 to cope with severe poUutionin Thailand. In order to meet the new specifications, certain modifications in the Bangchak Petroleum refinery are required. Bangchaks consultant completed optimum process redesign in March 1993. The proposed Environmental Improvement and Clean Fuels Project would provide the additional refinery facilities required to meet Thailand's new clean fuel standards prior to year 2000 in addition to upgrading safety and environmental operations. The project scope is to add an FCC unit for improving gasoline product quality, a deep gas oil hydrodesuifirization unit for improving diesel product quality and associated facilities including enviromnental controls.
2 New gasoline standards. The city of Bangkok currently experienced high pollusion from automobiles; therefore a new specification for gasoline has been promulgated. The specification will require reduction of aromatic content to 35% by volume. Benzene content will be probably reduced further. Leaded gasoline will be eliminated totally by the end of the 1990s.
3. New diesel fuel standards. The sulfur level of diesel must be reduced to 0.25% by weight initially by 1996, and to 0.05% by weight by the year 2000. Since heavier hydrocarbons do not burn as completely as lighter fractions, in order to reduce the particulate emissions from diesel engines, the boiling range and specific gravity of diesel will also be reduced.
Project Description and Analvsis of Alternatives
4. The Bangchak refinery is located in Bangkok, 25 km upstream from the Gulf of Thailand on the east side of the Chao Phya river. The land is undeveloped on the other side of the river. Along the northwest the refinery borders a Petroleum Authority of Thailand (PTT) terminal, and to the northeast lie some low density housing area. To the east of the facilitiy there are army barracks. A plywood factory lie to the south of the refinery.
5. The refinery consists of two hydroskimmingplant called Plant No. 2 and Plant No. 3 of total capacity 105,000 barrels per calendar day. Crude oil is shipped to the refinery via ship and railway. Products are shipped out of the refinery via tank truck, railway and pipeline. There are five piers along the riverfront on the west side of the refinery operated by Bangchak. A newly commissioned pipeline will transfer some of the productsto|a terminalin the north replacingheavy tank truck traffic. Products are also transferredto PTT terminaladjacent to the refinery.
6. Bangchak completeda major restructuringproject in May 1993. Revamping of Plant No. 3 was completed in 1989. Plant No. 2 which was a renovated plant was completedin May 1993. Under the project,the refineryfacilities were rehabilitatedand mechanicalreliability was restored to a level meant to exceed international safety standards In addition,refinery operations were broughtup to Thailandenvironmental standards. Prior to the construction,environmental impact assessment of both projects were preparedand submited to Thaigovernment authorities for approval.
7. AfterNEPO promulgatedthe new cleanfuel standardsin 1992, Bangchak engaged a consultant to identify the most economical and cost effective as well as environmnentalyappropriate option to meet the clean fuels requirements. The four processingconfiguration were studied. Finally,FCC unit together with gas oil deep hydrodesufrization unit was selected based on their superior economic and environmentalbenefits. Bangchak has then embarked on the Environmental Improvementand Clean Fuels Project to installthe facilitiesincluding vacuum gas oil distillation unit, fuel gas treating unit, sulfur recovery unit, FCC unit, flue gas desulfurizationunit, gas oil deep hydrodesulfurizationunit. . The project would include additional emissionsand effluentscontrol and treatment process equipment requiredto handle additionalloadings from the added refineryprocess equipment,as well as upgradingcurrent pollutioncontrol facilities.
BaselineData
8. After the completionof restrucuring project in 1993,Bangchak has monitored ambient air quality, water quality, workplace exposure, emissions and effluents accordingto Thai regulations. The environmentmonitoring plan currentlycarnied by Ban,chak is shown in Table 1.
9. Ambientair quality monitoringaround the refineryarea performedby the Pollution Control Departmentindicates the level of SOx is in the range of .009-0.10 mg/cu.m. which is lower than Thai standard at 0.3 mg/cu.m. Other parameters monitored includedcarbon monoxide(CO), oxideof nitrogen(NOx), and particulates. One year average monitoringdata indicatesthat ambientair qualityaround the refineryarea is withinThailand standard limitations and WorldBank guidelines.
10. Water qualitvand ecologyof the Chao Pha river. The Chao Phya river flows north to south past the refinery. The ThailandEnvironmental Board classifiedthe section of the Chao Phya river in the area of the Bangchakrefinery (7-62 km. from the river mouth) as class 4. Class 4 water is descnbed as water source used to receive discharnedwater from variousactivities, usable for industrialand consumptionpurpose subject to prior sterilizationand specialtreatment, for the qualityof water is below the standard. Water quality monitoringcarried by Bangchak indicatesa high level of sewage and possiblyindustrial pollution: coliform and fecal counts are comparableto untreated sanitarv wastewaters, conductivityand chlorides are high, and dissolved oxygenlevels are below those which would support fish. There is little differencein
2 terms of pattem of pollution,between the stations upstream and downstream of the refinery.
11. Performanceof existingenvirornmental control. Air emissionsand wastewater effluentmonitoring indicates the existingrefinery is currentlyoperating within Thai standardsand WorldBank guidelines.
12. Air emissionsmonitoring Emissions from the refinerystacks are monitoredby Bangchak- Parameters monitoredinclude carbon monoxide, hydrogen sulfide, oxides of nitrogen,oxide of sulfurand particulates. One year's monitoringdata indicatesthat Bangchakis operatingwithin Thailand emission standard limitations. Thailandair emissionstandards set a limnitof 1,000parts per million(ppm) on sulfurdioxide (SO27). The standardsare set by concentrationonly, and not by mass loading;however, dispersionmodeling were used in the permittingprocess. Bangchakrefinery is targeting400 ppm as emissiongoal. Againsta standardof 400 ppm,the emission measuredfrom the refinerysources is between 16-437ppm.
13. Effluent monitoring. Sample analysesare conducted by Bangchak laboratory. Samplesare taken in the three guard basinsonce a week except in the dry season. The guard basins are equipped with skimmingweirs and are the points of discharge into surface water. One year of effluent monitoringdata indicatesthe Bangchakfacility is currentlymeeting effluentstandards.
14. OccupationalExposure monitorin2. Workplaceexposure monitoringwas carried out for carbon monoxide,hydrogen sulfide, oxides of nitrogenand sulfur. particulates, organic lead and 1,-1,1-TCE.Identified workplace areas are monitoredfor noise levels and heat. Staff with potential exposure to lead are tested for blood and urine lead levels. Completephysicals are given once each year, includinghearing and respiratory systemchecks.
Environmental Impactsand Mitigation
15. A summary of the existing refinery and Clean Fuels Project ennronmen:al impacts and mitigationplan is shown in Table 2.
16. Air emissionscontrol. The new units will have emissionscontrol equipmentand facilities such as flue gas desulfurizationunit, electrostatic precipitatorfor FCC unit, sulfur recoveryunit, tail gas treating unit. , designedto meet both Thailandand World Bank standards. The Thailandemissions standard for S02 of 400 ppm would be used as process design criteria. The World Bank emissions standard for SPM of 100 mglcu.m.would be used for design criteria of the ESP unit for FCC unit. In addition, Bangehak has been using combinationof sweetenedfuel gas (90% of total usage) and low sulfur(0.5%by weight) fuel oil (10% of total usage). The S02 emission from these sources are low. Dispersionmodeling for the existingrefinery was performed in the Envirornental Impacts Assessment report of the restructuringproject. The results indicated that the highest average concentrationof S02 in one year period based on SO2 loading of 6.4 tons per day was 13.23 microgram/cu.mwhich was
3 below Thailand standard of 100 rnicrograx/cu.m.and the WorldBank standardof 50 microgram/cu.m.
17. New dispersionmodeling of the refineryafter installation of the new units will be performedas design parametersof the new project units are finalized. The dispersion modelingreport for the CleanFuels Project will be sent to the World Bank for review by August 15, 1994. It is preliminaryestimated that SO2 loadingof the future refinery will be about 5.9 tons per day which is lower than the WorldBank criteria of 500 tons per day.
18. Water quality. The flow of the existingrefinery wastewater effluent is about 0.05 cubic meter per second comparedto the flow of the Chao Phya river whichvaries between 500 and 1000 cubic meter per second. The refinery is currently operating withinThailand effluents standard limitations. All new wastewatertreatment systemto be added along with the additionalrefinery units in the Clean Fuels Project will be designedto exceed current Thailandstandards for effluents. In addition, wastewater from the guard basin receivingthe effluent flow will be partiallyrecycled within the refinery. Given these factors, the impactsof the refineryeffluent are consideredto be the minimal,and ecologicallyinsignificant
19. Planned exMansionto the WastewaterTreatment System. The planned expansion would includeoily surface water drainsfrom the new units, and an additionaloily storm water pond. Bangohak plans to installanother dissolvedair floatation unit. Another activated sludge system is plannedwhich would operate in parallel or series with the current system and a sand filter will also be installedbefore the guard basin for total suspended solids remnoval.The second activated sludge system would be added in order to target phenol as well. Phenol is not currently a problem in the refinery's effluent. However, the additionalcrackdng unit would increasephenol concentrations in the effluent. The target phenol concentrationin the effluentwould be 1 milligram per liter.
20. Impacts on land use. Since the CleanFuels Project will be implementedin the existingrefinery area and there is no expansionof land use, the project will not affect the communityland use area
21. Impacts on transporation. Afterthe completionof the CleanFuels Project, there wil be a net increase of 0.7% of products from the refinery. Considered that the products will be partially transferred by the new pipeline connected to Bangchak terminalin the north, the transporationof products will be decreasingand this will not much affect transporation.
22. Impacts on community Surveys and interviews conducted on governmental officialsand communitiesaround the refinerywere done for the restructuringproject in 1991. The survey showed that about 63.4 per cent of the population agreed that Bangchak expand the capacityof the refinerywhile 25.8 per cent did not agree and 10.8 per cent had no idea. The surveyalso showed that 8% of the total population in the area was disturbed by smell of oil, 28.6%Meof the populationwas concemed with accidentwhich might occur from the refinery. In the survey, it was suggestedthat the refineryshould plan its transporafionperiod so that it would not cause trafEc jam, the
it refineryshould check its loading and unloadingequipment regularly to prevent any accident.
23 Occupational Health and safety From the survey study related to public occupationalhealth, it was indicatedthat this issue has been taken care by Bangchak, by public hospitals, by private health centers, etc awidthis will not affected by the project.
IndustrialHazard
24. Risk assessment. A risk assessmentwas performedfor the Bangchak refinery before the emergencyplan was made. Another risk assessmentwould have to be completedbefore plant expansion. A consultantwill be contracted to perforn the assessment. The new units will be designedto include control and safety system similarto the existing plants to prevent any hazard, fire or explosion. Safeguarding systemsfor process facilitiesespecially FCC and Gas Oil HDS unit will be designedto ensurethat the integrityof the facilitiesis maintained.
EnvironmentalManagement and Traiging
25. Bangchak establishedan OccupationalHealth, Environmentand SafetyCommitee to establish corporate policy with respect to occupationalhealth, enviromnentand safety. Safety team was also set up to review safety conditionsin the refinery in additionto functional group of safety in Bangchak organization. All works in the refineryare subject to prior approvaland checldngof flammablegas or vapor around the workingarea Alarm and plant control systemare connectedto the centrol control room where any unit can be shutdown in case of emergency. Emergencyplan, spill prevention control and countermeasureplan has been prepared for use in case of emergency or accident in addition to operating procedures prepared according to internationalstandards. Bangchak-has fire suppressionsystems designed according to internationalstandards such as NFPA. Bangcbak also cooperates with other oil companiesin an organizationto control spill. Trainingof operators with respect to operationsof the plant and safetyare regularlyconducted.

9 ChaDter 1 Policy and Legal Frame Work
1.1 Overview
The National Energy Policy Office (NEPO) of Thailand promulgated new clean fuels standards in late 1992 to cope with severe environmental problem resulting from increasing economic growth. Specifications of gasoline and diesel will be changed to mitigate the adverse impacts on enviromnent. Time frame for changes of product specifications is shown in Table 1.1. In order to meet the new fuel specifications, certain process modifications in the Bangchak refinery are required. Bangchak's consultants completed process identification and optimization study together with a conceptual design with unit capacities in March, 1993. Bangchak has embarked on Environmental Improvement and Clean Fuels Project in order to install additional process units to improve product qualities to meet expected standards before the year 2000. The project scope is to add an FCC unit to facilitate the production of gasoline of the required specification, a deep gas oil HDS unit to comply with the diesel specifications and associated facilities including environmental controls.
New gasoline standards: The city of Bangkok currently experiences high pollution from automobiles; therefore a new specification for gasoline has been promulgated. The specification will require reduction of aromatic content to 35% by volume. Benzene content will be probably reduced further. Thailand refineries are now required to eliminate lead (0.013 mgliter) totally by the end of the 1990s.
New diesel fuel standards: The sulfur level of diesel must be reduced to 0.25 wt. percent initialy by 1996, and to 0.05 wt. percent by the year 2000. Since heavier hydro- carbons do not bum as completely as lighter fractions, in order to reduce the particulate emissions from diesel engines, the boiling range and specific gravity of diesel will also be reduced.
1.2 Preparation of Environment Impact Assessments and Mitigation Plans
Thailand regulations require Bangcbak to perform an environmental assessment (EA) for the facilities to be added to the refinery. In order to obtain govermmentapproval, it has to be established that emissions from the new as well as existing facilities will not result in an increase in ambient concentrations of pollutants beyond levels set by the appropnate Fnviromnental agencies and also that emissions will not exceed established permissible levels.
Emission standards are regulated by Ministry of Industry. Prevailing standards are shown in Table 1.2 - 1.4. Ambient air standards regulated by Pollution Control Depart- ment, Ministry of Science, Technology and Energy is shown in Table 1.3. Industrial effluents standards is shown in Table 1.4.

1-6 Chapter 2 Proiect Desisg ODtimizationand Description
2.1 Introduction
The Environmental Improvement and Clean Fuels Project (ICP) has as its objective to provide the equipment and processing facilities needed to meet the Royal Thai govern- ment's clean fuel specifications. The EICP follows the just completed refinery restruc- turing project, which included major modifications to the refinery, including expansion of refinery capacity from 65,000 barrels per calendar day (bpcd) to 105,000 bpcd. A complete Environmental Impact Assessment was done for the refinery restructuring project in 1992. The EA for the proposed EICP is an extension of the work done for the restructuring project. This EA is based on design work done up to now on the EICP and will be reviewed and revised as appropriate when the detailed design work is completed.
2.2 Analvsis of Alternatives and Design Optimization
The clean fuel specifications mandated by the Royal Thai Government (RTG) will have wide-ranging impact on the refinery's products. The primary specification changes involve elimination of lead and reduction of aromatics and benzene levels in gasoline and reduction of sulfur and boiling range of diesel oil. Bangchak engaged Chiyoda Corporation to identify the most economic and cost-effective as well as environmentally appropriate option to meet the clean fuels require-ments. The four processing,configu- rations were considered:
(i) Deep gas oil hydrotreating, which reduces the sulfur content of diesel oil from 1.00 wt % to 0.05 wt %; (ii) a hydrocracker, which would convert low value vacuum gas oil to primarily premium quality high value diesel oil with neglegible sulfur (c 2 ppm), with a deep gas oil hydrotreater to reduce the sulfur content of straight-run gas oil; (iii) a fluid catalytic cracker (FCC), which would convert low value vacuum gas oil to high quality gasoline, and some middle distillates and LPG together with a deep gas oil hydrotreater; and (iv) a reduced crude catalytic cracker (RCC), which could convert residual fuel oil to products similar to that from a FCC but of lower yield and quality, together with a deep gas oil hydrotreater.
2.3 Except for the FCC and RCC options, the other two require the import of FCC quality, high octane, low aromatics and benzene gasoline, which are virtually unavailable on a long term basis in large quantities. The RCC has an inherent deficiency - it would produce about 5 tons per day (tpd) of spent catalyst compared to 1 tpd from the FCC. Hence the final comparison was confined to the Deep Gas Oil Hydrotreater (DIGHT), the Hydrocracker with a DGHT and FCC with a DGHT. Tables 2.1 to 2.3 which follow indicate the relative merits of the three options. Based on this comparison the FCC with the DGHT was selected, both for their superior economic and environmental benefits.
2-1 Proiect Description
2.4 The proposed Environmental Improvement and Clean Fuels Project (EICP) would provide the additional refinery facilities required to meet Thailand's new clean fuels standards, in addition to upgrading safety and environmental operations in order to meet expected standards into the year 2000. The Bangchak refinery is located in Bangkok, along the Chaophraya river. The land is undeveloped on the opposite bank. Along the northwest the refinery borders Petroleum Authority of Thailand (PTT) products terminal, and to the northeast lie some low density housing areas. To the east of the facility there are arrny barracks. Industrial facilities lie to the south of the refinery, (see site location map, figure 1).
2.5 Crude oil is shipped to the facility via ship and railway. Product is shipped out of the refinery via tank truck, railway and pipeline. The railway loading racks and piers are located along the west side of the facility, and the truck loading racks are located in the southwest corner. There are five piers along the riverfront on the west aide of the facility operated by Bangchak. A newly commissioned pipeline will transport some of the product out of the facility, replacing the heavy tank truck traffic. The existing pipelines will continue to deliver products to the PTT terminal adjacent and rorth of the Bangchak Refinery.
2.6 The existing refinery comprise the fbllowing:
1 x 40 kbd crude distillationunit 1 x 80 kbd crude distillationunit 2 x 7 kbd catalytic naphtha reforming units 1 x 18 kbd gas oil hydro-desulfurization unit I x3 kbd LPG merox unit 1 x 10 kbd Kerosene merox unit Associated off-site and utilities 91 Bulk storage tanks for crude oil and products 3 LPG spheres 6 LPG Bullets
2.7 The proposed project will include the following principal process facsl::ies
I x 16,000 bpsd FCC I x 24,300 bpsd DGHU Fuel gas desulfurization unit Sulfur recovery unit Waste water and other effluenttreating facilities.
2.8 A.block flow schematic showing unit capacities and production at design capacity are given in figure 2; charge and products are presented in Table 2.4 for the overall refinery (including new facilities) and finished products specifications are given in Table 2.5. Material balances are also provided for the following:
- Vacuum distillation unit (VDU) (Table 2.7) - Fluid catalvtic cracking (FCC) unit (Table 2.8) - Flue gas desulfurization section in FCC unit (Table 2.9) - Gas oil deep HDS unit (Table 2.1 0)
2-2 - Existing gas oil HDS unit (Table 2.11)
throughputand capacitiesare shownin Table 2.5 and productsquality in Table 2.6.
2.9 Utility consumption is summarized in Table 2.12. Refinery energy requirements are suppliedby three types of fuels; refinerylight hydrocarbongas, residualfuel oil and a mix of the two liquid and mixed fuels. Mixed fuels are in the followingmixng ratio based on their heat.
Mixingratio - heat duty basis - Fuel Oil 85.5% Fuel aas 14.5% Total 100.0%

Catalystand chemicalconsumptions for the major in new process unit are presentedin Table2.13.
2.10 Overall Utlity Balance for the Refinery: Utility balance includingcorsumption and production in process, uaility,offsite and miscellaneousfacilities is presented in Table 2.14. Capacityof utilityfacility is given inTable 2.15.
2.11 CaRacitv of New Utilitv Facilitv
Additional electric power demand is only 0.7 MW. A Gas turbine generator is proposed to be installedat 5 MW rated to satisfythe demandand reduce electricpower import. The fired boiler operates only to generate steam for process usage. A 580 Nm/lhr air compressorsystem is provided.
2.12 Bulk Products Movements
Bangchakimports the majorityof its crude oil from the Middleand Far East to Sriracha on the eastem coast in large tanklersand then transferredto the refineryby 3,000-7,000 DWT barges. About 6.5 tripspbybarge are required. This is well withinthe capacityof the wharf

HOS 2-25 , ______Chapter 3 Base Line Data 3.1 PROJECT LOCATION This project is located at 210 Sukhumvit 64, Bangchak, Phrakanong District, Bangkok, (Figure 3-1). The total area of the refinery covers 480 rai, of which 462 rai will be appor- tioned to the refinery and 18 rai to wharf. The refinery borders the following sites: Northern end : Bangchak canal and Petroleum Authoriry of Thailand's oil tenrinal Southern end : Bang Oh canal and the Thai's plywood factory Westem end : the military's compound, Soi Sukhumvit 64 and Express way Eastern end Chao Praya River 3.2 PHYSICAL ENVIRONMENTAL RESOURCES 3.2.1 Meteorological Conditions (A) General Meteorological Conditions Being located in Bangkok City, the project enjoys the central-region tropical rainy climate. South-western monsoons blow accross the Kingdom from February to September (a total of eight months). From October to January, the country is affected by monsoons from the northeast (a total of four months). The central-region of Thailand is influenced by three distinct seasons. The summer starts from mid February, ending in the middle of May. From mid May until half the month of October is the time for the rainy season after which comes the cool season. Considering that the project is located very close to Bangna air-monitoring station, it thus uses the data, for a thirty year-period (1959-1988), gathered by the Climatology Division, The Meteorological Department and distributed from that particular station. From this study, data could be summarized as indicated in Table 3-1. • The highest average temperature was 35 C. The lowest temperature averaged at 21C. The year-round temperature had an average of 28.4C. * The degree of rain fall peaked in September (345.6mm). January had the lowest amount of rain (8.0 mm). The year-round average rain fall was 1498.7 mm. Looking at wind direction and windspeed, southern winds blew accross Thailand from February until May which was during the south-western monsoon season. Between the month of June and September, the country received most winds from southwest. A frequent north-eastem and eastern wind occurred mostly in January during the time of the north-eastern monsoon season. In each month, windspeed averaged from 1-4.9 notches. The windrose diagram (Figure 3-2) at the Bangkok air-monitoring station indicates that in March, the wind was the most calm (18%/6).October was the month in which the wind was the least calm (44%). (B) Meteorological Conditions. A Variable in the Dispersion of Polluted Air Detailed and accurate meteorological data are necessary when calculating the dispersion of air pollution: the average of wind direction and windspeed during each hour, atmospheric stability, the temperature and polluted air mixing height. 3-1 i zusoa £utrnsaM AFI 1a E Pir UOTtDOI q 0a[o IJ,4 I-£ _1 t!'"@ni - =^" . / I", I . _J <$ /.. .. 5 t r) t . .

In this case, Bangna station and Donmuang station would be two fuindamnentalsites. On the other hand, the calculation using a mathematical model has employed surface data collected from the Bangkok station in 1990. The latest data disseminated from Meteorologocal Department Radiosonde data were also collected from the Bangkok air-monitoring station. 3.22 CarrentAir Qality The objective of conducting a study on air quality presently is to determiine the level of air quality during the time which the refineries are in operation: producing oil at 68,000 barrels per day. Data have been continuously collected from the observations of air quality since 1989. Both ambient air quality and air quality at the funnels are being monitored. Table 3-2 illustrate the index used and the frequency of the measuring process. Table 3-3 shows the method employed in collecting data and the analyzing procedure. The results of each and every measurement have been compared and displayed in Tables 34 and 3-5. The following could be concluded: (1) Air Quality in Ambient The production process in use today consists of process heaters and boilers. From the first stage of evaluation, pollutants could be emitted into the atmosphere within the range of 1-2 kilometeres during normal conditions. Under windy conditions, pollutatns could be dispressed into the atmosphere as far as 5 kilometers. Seasonal wind direction plays an important role when chosing the sampling location: the north-eastern monsoon, South-western monsoon and the south wind. The slightly populated conununity and several schools with approximately a little over 1000 students situated in the areas directly surrounding the refinerv have the highest risk of being affected by the pollutants. Therefore, the following four sampling location have been designated as the major locations used to measure air quality: Site Al - Somthavin School Site A2 - Wat Bangna Nok School Site A3 - Ban Ubakekha Detention Center Site A4 - Pipattana School These sites are situated above and below wind direction based on the different s * Al and A4 would be above the wind direction during the months of No; ember and January. Between April and July, these two sites would be under the * ind d:. e: :on A2"and A3 would be above the wind direction in April and JulY They would bc below the wind direction November and January. Air Quality Index Pollutants which are being monitored and measured according to the regulations made by the Office of National Environment Board (ONEB) are: total suspended particulate (TSP), sulfur dioxide (S02) and nitrogenoxide (NO2). Measuring Results Air quality which has been monitored and measured in all four sites since April of 1993 in five periods (Table 3-4).

The highest level of TSP was recorded in July of 1993. The average was 0.563 mg/m3 . In general, the level of TSP measured at sites located above the wind direction is lower than that measured at sites situated below the wind direction. Sulfur dioxide (SO2 ): Every samples taken for sulfur dioxide in all four sampling loca-tions is below air quality standard requlated by ONEB (the standard was set at 0.300 mgf m3). The highest level of S02 was found at site Al-Somthavin School (averaging at 0.047 mg/m3 ). Nitrogendioxide (NO2): Environmental impact assessment (EIA) conducted previously at each site indicates that the level of N0 2 in ambient is lower than the regulated standard and more over, the record did not seem to significantly change over time. NO2 was measured to be at its highest level in January and lowest in April of both years. (2) Air Quality at Chimneys Presently, the refinery has five main stacks namely: * TPU which is 56 meters high, has a diamneterof 2.5 meters and a flow of air at the rate of 47,800 Nm3/h. * CRU which is 26.9 meters high, has a diameter of 1.0 meters and a flow of air at the rate of 18,900 Nm3/h. * Boiler which is 50 meters high, has a diameter of 2.5 meters and a flow of air at the rate of 10,980 Nm3/h. * Comnmonstack which is 70 meters high, has a diameter of 4.8 meters and a flue gas flow rate of 259,668 m3/h. * Gas Oil hydrotreating unit which is 23.5 meters high, has a diameter of 10.4 meters and a flue gas flow rate of 19,080 m3/h. Table 3-5 shows the results of air quality measured at stacks of which the following could be concluded: * TSP: The level of TSP emitted from TPU CRU and Boiler is much lower than the standard permitted by the Ministry of Industry. Similarly, the level of TSP emitted from GO-HDT and common stack which has been measured since November 1993 is lower than standard. Today, the level of TSP emitted from all stacks (except common stack) significantly decreases from previous years. * SO2 : The level of S02 measured at stacks was reported to be lower than the standard set by the Ministry of Industry. The most recent measurement indicates that the level of SO0 emitted into ambient has decreased tremendously, particularly S0 2 emitted from Boiler and common stack. • N02: The level of NO2 measured at stacks was also reported to be lower than the standard set by the Department of Industrial. The latest result measured in April 1993 displays that the amount of NO, emitted from the stacks was only 2.4-1.6 mg/m3 (the standard was set at 470 mg/m3 )_ * CO: Similar to TSP, SO2 and NO2 , the level of CO emitted into ambient is very insignificant, particularly when compared to current standard level (1,000 mg/m3). 3-11 * nt 2 b: ite ievei or fl2b enuLteu lito amoient U;an nOL UCLeCGLUlJC%ULeLCLJULIUI MAS Lb U. mg/m3 ) whereas the standard was set at 140 mg/rm3. In conclusion, the level of pollutants namely TSP, S02, N0 2 , CO and HES emitted from the refinery's stacks: TPU, Boiler, CRU, GO-HDT and common stack is much lower taan the standard. 3.2.3 'he Hydrology of the Chao Phraya River The section of the Chao Phraya River that runs through the project area is said to be in the lower part of the river, which starts from Chainat Province and runs southwards through the Province of Phra Nakhon Si Ayutthaya, Nonthaburi and Bangkok into the Gulf of Thailand in the area of Muang District, Samut Prakan Province, the length of which part is approximately 241 kilometers. The estuary area would be influenced by the tides of the sea, especially in January to May, which would give rise to the pressure of the sea water into the river for a long distance, and in order to prevent the invasion of the brine, water must be discharged from Bhumiphol Dam in the upper part of the Chao Phraya River basin zone at a rate exceeding 75 cubic meters/ second, which would keep the depth of the river at such a level that permits navigation. So the flowing of the current in the Chao Phraya River would be controlled by Bhumibhol Dam and Chao Phraya Dam. From the data showing the rate of the flow of water between 1985 - 1988, provided by the Water Quality Subdiv .. nL,Environmental Quality Standards Division, office of the National Environment Board, it is found that the lowest flow rate is in the period of April to June, which is approximately 50 cubic meters/second, and in the period of August to December which is the period of prevailing rainfall, the flow rate would rise, the highest rate being approximately 4,000 cubic meters/second, and on average the normal flow rate of the Chao Phraya River is approximately 1,000 cubic meters/second. When the character of the section of the Chao Phraya River that runs through the project area is considered, it is found that its character is that of a bend of a river. Added by the alterations of the flow of water, it works favorably in ermnsof the economics of navigation in that there is no need to dredge or maintain the water channel for navigation purposes in this area. This is why the water level in the area of Bangchak Wharf has a sufficient depth for navigation throughout the year; and from a water-depth-sounding survey by the Ports Authority of Thailand in 1986, which also covered the area in front of the wharf of Bangchak Company as shown in Figure 3-3, which shows the character of a river bed with a depth contour of 10 meters from the lowest ebb-tide level in the parrallel direction and close to the landing line of WTharfNo. 2 (Wharf 1 SD), the width of the water channel for a depth contour of 10 meters is approximately 150 meters The landing area of Wharf No. 3 provides the character of a basin about 14 meters deep from the lowest ebb-tide level, and with an average area of 25 x 280 meters, which is usable as a basin for turning back vessels. In addition to this, the river bed area continuing from Wharf No. 3 to Wharf No. 6 (Wharf 1SA) is a deep water channel about 25.50 meters wide and 13 meters deep from the lowest ebb-tide level. Such character gives rise to local erosion due to the influence of the current near the river bend, which would usually lead to the erosion of the banklof the inwardly curved portion of the river bend. 3.2.4 The Quantity of Deposits in tle Chao Phraya River Almost all of the deposits in the lower part of the Chao Phraya River are from the water receiving areas of the upper part, while those deposits generating from the river banks or mixing with waste water from industrial works are in a small quantity.

In a year cycle a quantity of approximately 4.7 million tons/year of deposits are carried along frr:m the north. The major part of the deposits, approximately 4.5 mnilliontons, are carried along during the rainy season between August and October, while in the dry season only 0.2 million tons of deposits are carried along. Of the total quantity of deposits, about 0.5 million tons would settle between the mouth of the Chao Phraya River and Km. 52 from the river mouth, and about 0.7 million tons of deposits would settle in the portion between Km. 52 and Km. 112. As for the density of deposits, it is found that during the dry season the density of deposits averaged throughout the depth of water varies between 178 per million at Km. 52 and ?49 per million at the month of the Chao Phraya River, while in the rainy season the density of deposits in the said portion of the river does not vary significantly, i.e. having a value between 327 and 336 per million. 3-2.5 The Quality of Water ofthe Chao Phraya River The quality of the water of the lower part of the Chao Phraya River would depend mainly on the manner of land use in the area of the Chao Phraya River basin, which may be devided into different zones according to utilization as follows: (1) The Agricultural Zone Covers the areas of four provinces, namely Phra Nakhon Si Ayutthaya, Pathum Thani, Nonthaburi and Bangkok Metropolis; various wastes discharged into the river generate from housing and farming in large part. (2) The CommunityZone Is the area of Km. 40 from the river month to Km. 60. The Rama VI Bridge area is an area in Bangkok that is densely populated; there are small-scale industrial works in lare part. Almost all of the waste waters from these communities and industries would be discharged into the Chao Phraya River through various canals. (3) The Industrial Zone Is the area of Km. 40 from the river mouth downwards, e.g. the areas of Ratburana District, Phra Pradaeng District, Muang District, Samut Prakan Province. Industrial works in this zone are numerous and large, and so the quantities of water discharged into the Chao Phraya River are significant. As a result of the said maimer of land use, the index of quality of the river varies with the distance from the oriainating source of pollution to the river mouth, and from the conduct of an "inspection of the quality of water throughout a distance of about 380 Kilometers of the Chao Phraya River by the Office of the National Environment Board in 1988, it was found that the lower part of the Chao Phraya River from the river mouth in Samut Prakan Province up to Nonthaburi Province had an oxygen dissolution level lower than 2 milli-gram per liter, which was lower than the prescribed minimum standard of 2 milligram per liter. Particularly in the portion from the Memorial Bridge to Bangkok Port, which is the critical spot of the quality of the water of the Chao Phraya River, th eoxygen dissolution level was very low, i.e. lower than I milligram per lier; while the portion of the lower part of the Chao Phraya River from Nonthaburi Province up to Phra Nakhon Si Ayutthaya Province, which was designated as a 3-14 water source of the third category, and the portion of the upper part of the Chao Phraya River from Phra Nakhon Si Ayutthaya Province up to Nakhon Sawan Province, which was designated as a water source of the second category, were found to have oxygen solution level lower than the standards of the two categories of water sources prescribed at not lower than 4 and 6 milligrams per liter respectively. The level of contamination in the form of BOD had a rising trend every year in the portion from the river mouth up to Nonthaburi Province, a level not exceeding 4 milligrams per liter, while in the portion of the lower part of the Chao Phraya River from Nonthaburi Province up to Phra Nakhon Si Ayutthaya Province up to Nakhon Sawan Province the BOD level was within the standard. As regards the quantity of coliform bacteria, it was found that there was also a rising trend. Particularly in the lower part of the Chao Phraya River from the river mouth up to Nonthaburi Province there was a quantity of coliform bacteria higher than 50,000 MPN per 100 milliliter, while in the upper part of the Chao Phraya River from Nonthaburi Province up to Nakhon Sawan Province there was a quantity of coliform bacteria from 2,900 - 20,0007PN per 100 milliliter. However, it was found that in the upper part of the Chao Phraya River, the quality of which was regarded as being at a positive level, in 1985 - 1988 there was a quantity of coliform bacteria higher than the prescribed maximum standard of 5,000 MPN per 100 milliliter. As for the quantities of heavy metals, e.g. mercury, cadmium, lead, copper, zinc, chromium and toxic substances like cyanide in the whole of the Chao Phraya River, it was found that they were within the standard, while compounds of the organochlorine catego-ries of insecticides were found to exist in a very small quantity and not to be dangerous to lives in the water. The results of the analyses of the quality of water on the average in the Chao Phraya River from 1981 - 1988 are shown in Table 3-6, with changes in the quantity of oxygen dissolved in water and changes in the BOD quantity of the Chao Phraya River from 1935 - 1988 being shown in Figures 3-4 and 3-5. 3.26 Water Qualit Anaysis in the Chao Phraya River and in GuardBasins The quaIity of water of the Chao Phraya River in the project area which is at of Kms. 23 - 25 from the river mouth is classified to be in the industrial zone and standard of water of the fourth category. From the.regular checking of the quality of water of the Chao Phraya River in the project area by Bangchak Petroleum Public Co., Ltd., with such sample collection spots as shown in Figure 3-6, i.e. the collection spot No. 1 in the area of the mouth of Bangchak canal, which is an upstream of the project area; the collection spot No. 2 beside the project area; the coRlectionspot No 3 in the area of the mouth of Bang-oh canal; the collection spot No. 4 in the area in front of Thai Plywood Factory, which is downstream of the project area. The analysis of Chao Phraya River water and refinery wastewater in the past one year are illustrated in Table 3-7 and Table 3-8 respectively. The following conclusions was made: (1) Oil and Grease (FOG) While the concentration of oil and grease in treated wastewater has values ranging bet-ween 0.6-10.0 mg/litre, the concentration of oil and grease in Bang Oh canal and in Bang-chak canal has values which ranges from 0.5-2.8 and 1.0-2.6 respectively. The concentra-tion of oil and grease in the Chao Phraya River has values ranging from 0.6 - 2.8 mg/litre. 3-15 Table 3-6 Chao Pliraya River Water Quality on the Average from 1981-1988 Distanice froml Inidex Standard 1981 1982 1983 1984 1985 1986 1987 1988 RiverMoutil _ Km. 7-62 DO, mg/I 2.0 1,1 1.5 1.2 1.3 0.8 1.0 1.3 1.3 Water Quality BOD, mg/l 4.0 2.2 2.2 2.2 1.9 2.6 2.8 3.4 3.2 Class 4 Colifonrn - 63000 > 6700 209300 163000 372000 236000 223000 192000 MPN/100 ml Cd, mg/i 0.005 , 0.05 - - <0.0005 0.009 0.0003 0.0008 0.0007 0.0008 Pb, mg/i 0.5 - nd 0.012 0.008 0.0036 0.008 0.012 0.002 Hg, mg/l 0.002 - 0.005 0.0003 0.0002 0.0003 0.0002 ird Salinity, ppt - - 2.9 2.8 2.6 4.2 - 4.3 1.5 Km. 62- 142 DO, mg/I 4.0 4.5 5.1 4.4 4.1 4.5 5.2 4.3 4.3 Water Quality DOD, mg/l 2.0 1.5 1.1 1.2 2.1 1.7 1.2 1.2 1.7 Class 3 Coliform, 20000 33700 15700 16800 14600 19400 6900 29000 25000 MPN/100 ml Cd, mg/I 0.005 , 0.5 - - <0.0005 0,0004 0.0001 nd 0.0003 0.0002 Pb, mg/I 0.05 nid < 0.005 0.012 0.002 0.002 0.013 0.0015 Hg, mg/I 0.002 - < 0.0001 0,0002 0.0002 nd 0.0003 nd Salinity, ppt 0-0 0 0 - 0 0 Knm.142-379 DO, mg/l 6 I- 7.0 7.2 7.0 6.0 - 6.8 6.0 Water QuAlity BOD, mg/I I S 1.2 1.9 2.1 0.9 - 1.3 1.4 Class 2 Colifonnr, 11800100(() 9000 12000 - 5600 8000 MPN/1100ml Cd, mg/I 0 0I , 0I - c 0.0005 0.001 0.0001 0.005 0.0001 0.0001 rb, tlg/I 0 (05 . 0.011 0.005 0.004 0.003 0.006 0.004 Hg, niig/l 0.002 - 0.0004 < 0.0002 0.002 nd 0.0001 id SaIinity, ppt -- 0 0 0 0 0 0 j- 1* TX Water Quality Level 2 Water Source Class 2 Water Quality Level 3 U _ _ 4 - ______ a >3 Water Source Class 3 h1 Water Quality Level 4 2 ______-2 3 Wr-aterSource Class 4 1988 Year 1985 1986 - / 1967 Figure 3-4 BOD Quantity of the Chao Phraya River from 1985-1988 rl Water Quality Level 4 3- CD Water 2.

N.D. = Nat Delectable I (2) Suspended Solid (SS) While treated wastewater emitted from the refinery has suspended solid dissolved in the amount of 8-34 mg/litres, suspended solid measured in Bangchak canal and in Bang Oh canal has values ranging from 15-270 and 14-315 mg/ltre respectively. Part of the Chao Phraya River which flows through the refinery has suspended solid with a value of 14-285 mg/itre. (3) Total Disolved Solid (TDS) While the total disolved solid in treated waste water emitted from the refinery has values ranging between 634-4,776 mg/litre, that in Bangchak and Bang Oh canals has values of 394- 10,528 and 392-11,024 mg/litre respectively. The total disolved solid in the Chao Phraya River is in the range 392-11,024 mg/litre. It is interesting to observe that the amount of the total disolved solid measured during the month of April 1993 has the highest value. (4) BOD5 While BOD5 in treated wastewater has a value of 3-10 mg/litre, BODS measured in Bangchak and Bang Oh canals has values between 6.8-21 mg/litre and 5.2-15.6 mg/litre respectively. BOD5 in the Chao Phraya River clostest to the project has a BOD5 of 6.8-19.0 mg/litre.. (5) Lead While the amount of lead measured in treated wastewater has a value of 0.001-0.020 mgditre, the amount of lead found in Bangchak and Bang Oh canal, as well as in the Chao Phraya River has values between 0.010-0.052 mg'iitre, 0.006-0.051 mg/litre and 0.009- 0.048 mg/litre respectively. This analysis shows that wastewater which has been treated and drained into the Chao Phraya River has various quality indexes very similar to water quality in the Chao Phraya River. Obviously, treated wastewater does not have a serious impact on the quality of water in the Chao Phraya River. 3.3 ECOLOGICAL RESOURCES Major bio-environmental resources in this project study are the eco-system in the Chao Phraya River, but since in the current situation the Chao Phraya River has been faced with the problem of water pollution due to the discharge of wastes into the river, the quality of the water of the Chao Phraya River worsens: Particularly in the period of months in which the flowing rate of the water is low, the severity of water pollutants would be significant, and from the quality classification of water services in the Chao Phraya River by the Office of the National Environment Board, the water source in the area of Kms. 7-62 from the mouth of the Chao Phraya River is classified to be a water source of the fourth category, which is a water source used to receive discharged water from various activities, usable for industrial and consumption purposes subject to prior sterilization and special treatment, for the quality of water is below the standard. Such quality of water will certainly affect the sustenace of animated beings in the water source. So in the water source of this area no major eco-system of aquatic animals is found existing. This study will deal with plankton and cash fishes in the Chao Phraya River which may be expected to be directly affected by the project in the event of any leak-agesof oil into the river by means of data from organizations having conducted studies in the most recent year. Plankton From the collection of plankton samples in the Chao Phraya River by Southea.t Asia Technology Co., Ltd., the Environmental SpecialistFirm in April 1986 for supplementinigto a study of the environmental impact of Bangchak rehabilitation project and by the wharfs in June 1988, which collected plankton samples at five spots in the Chao Phraya River, namely stLtions 1, 2, 4, 6 and 7 from the head end of the tide at the Port Authority of Thailand to the area of the tail end of the tide at the Naval Ordnance Department, and collected samples in the areas cf Khlong Bangchak and Khlong Bang-oh at Station 3 and 5 respectively, the study results in detail are shown in Annex 2, which contains a report on the discovery of plant planktons and animal planktons of various kinds, in summary as follows: - Plankton in the Chao Phraya River in the vicinity of the project area there are 22-26 families, of which those in the diatomaceous group (Phylum Chrysophyta) were found in the largest quantity, with a factor of abundance of 67-79%. The family found to be highly abundant was melosira; the plant plankton group second in abundance was Phylum Chlorophyta. The level of abundance of plant planktons in the Chao Phraya River in the Vicinity of the project area averaged 6.3 x 106 - 15.1 x 106 cells/cubic meter. - Animal planktons : 3-11 families were found, with a highly varying factor of abun-dance. No plankton of any kind was found at every sample collection spot. The level of abundance of animal planktons was between 19 x 103 - 77 x 103 cells per cubic meter. Cash Aquatic Animals Rachadabhorn and company from the National Institute of Freshwater Fisheries carried out a study of the number of kinds and the quantity of fish in the Chao Phraya River from the area of Pakkred District, Nonthaburi Province, down to the river mouth in Samut Prakan Province during the period of February to December 1990. They found that the majority of cash aquatic animals belonged in the fish group, consisting of 36 kinds (Table 3-9). The estimated total quantity of aquatic aninals was approximately 38.97 tonslyear. However, it was found that for the time being, particularly in the zone from Muang Nonthaburi District southwards there was a very insignifcant degree of fishing since the state of poUution of the Chao Phraya River caused the kinds and the quantity of aquatic animalsto decline significantlyin comparison with the past. 3.4 HUMAN USE VALUES 3.4.1 Land Use Based on surveys and studies conducted on town-planning maps coupled with land use maps in areas 100 square kilometers surrounding the project, land use in such areas could be divided into three categones: community compound, agricultural land and other land (see detail in Table 3-10 and in Figure 3-7). (1) Community Compound 73 percent of the area being studied could be categorized as a community compound which consists of residential, commercial, governmental, and industrial activities. In addition, there are several academic and religious institutions located in the compound: 92 schools, 30 temples, I christian church and four mosques. Land use in the community compound could be summarized as follows: : Q IZ - g -> h0@ \ ^4 .N\ l >I % - _ * _-. l l - -7 =-. si- M *.j -*; > > z 9X . 2 1 /_ -- tBang l ak refier *;- i9' .... .\ | \\ | 't X .' -~~~~~ tA_" _-. -;=7i-' E_-/4l- '*tS/-; l _ _- -

"SlumKlong Toey"is the home of blue-collarworkers at the port and in various industrialplants operatingin that area. Other slumareas are locatednot veryfar fromWat Tai, Soi Wat Rat Sathathum, PhrakanongVittaya School, VachirathumSathit School,Tanin Industrial Company,Soi Rung Ruang, Wat Bangna Nai and Pet Product Company.The total slum area is 1.8 percentof the total area beingstudied. a Home Garden: a traditionalstyle of homebuilding along the right-handside of the Chao PhrayaRiver usuallyknown as 'Bang Kra Chao",Amphur Pra Pa Dang in SamutPrakarn Province and along the PhrakanongCanal. For the past ten years, most home gardens have been constructedvery closedto one another.Today they are starting to decay and singlehomes have declinedwhile apartments and town houses are spurringup. Thistype of residentialarea composedof onlyfour percentof the total land area in the study. (B) Industrialand WarehouseArea The industrialand warehousearea used up 5.7 percentof the total land in the study. Located mainlyon Pu Chao SanmingPry Road, AmphurPra Pa Dang and along the left bank of the Chao PhrayaRiver, industriesin these areas are of all sizes with the majorityrequiring the benefitsof water transportation.For example,Bangchak Refinery, Thai Ply Wood Factory, Chao Phraya AgriculturalProduct Company,Saha Thai Paper Factory and Thai Scott Paper Factory.Small factories are scatterlylocated. (C) GovernmentalAgencies and TransportingStations Governmentalagencies which provide local public services are located scatterlyin the area with the two most significantagencies being the Naval Ordnance Department and the MeteorologicalDepartment Research Center. The transportingstation in the area is the Port Authorityof Thailand.This type of landusetakes up 5.7 percentof the total land area in the study. (D) Agriculturalland Agricultureis a very importantcharacter of landuse in SamutPrakarn Province particularly in the BangKra Chao area where the majorityof land is used for fruitplantations such as mango, banana, areca-nut, coconut and jack-fruit. The total area covers approximately3 -10 rais. These are distinctlyold orchardswhich lack attendtion.The new younger generationof the villagersoftenly migrate into the city, seeldng for jobs in factories, leavingtheir orchards unattendedand abandoned.The other area which is being used for agficulturingis Na Dum (the eastemside of the total area beingstudied), which adjoins between Prakanong District and AmphurMuang in SamutPrakarn. It is projectedthat such area would significantlychange in the nearfuture due to the effectsof the constructionof the PatanakarnRoad. Agriculturalland could be found about 20.4 percentof the total land in the study.

(E) OtherLand Area 6.5 percentof the total land area includedin the study is labeiledas 'other land". This type of land could be found along the water basinand along differentcanals. The Chao Phraya River whichflows throughthis type of land demarcatesBangkok and Sanut Prakarn. 3.4.2 Transportation Althoughthe Chao PhrayaRiver and the canalsplays a very significantrole for the community and commercein the past until today, ground transportationis increasing becomringvery importantfor public transportaionand importingand exportingof goods and resources.The accelerationof road constructioncreates a whole new networkof ground transporationwhich owes its popularityto the convenient,efficient and speed in gettingfrom one place to another. Nonetheless,in rural areas or in the local community,water transportationis still the main vehicle despite the fact that it is not as efficientas ground transportation. Through water transportation,a mass amount of goods and people could be transported at the same time. Collecteddata on groundand water transportationscould be summarizedas follows: (A) Ground Transportation The project could be accessed,through ground transportation,using Sukhumvit62/1, 64 or 64/1, or by usingNa Krom Road which parallelsthe Chao PhrayaRiver. SanpavuteRoad is also anotheroption (Figure3-8, Image 3-1). The surveyon traffic densitywas conductedby Aggie ConsultCompany Limited on May 1, 1990.Samples were takenfrom five points(Figure 3-9) three timesa day. The ways whichare beingused by Bangchak'semployees to get to work and the waysused for transportingof raw materialsand finishedproducts havealso been surveyedas follows: - Sukhumvit Road - Na Krom Road - paralleling the Chao Phraya River - Suklhumvit64 - the most direct way to reach the project site Samplesfor trafficsurvey conducted on al three roadswere takenbetween the hours of 8.00 - 9.00, 12.00- 13.00and 16.00- 17.00.The results are displayedin Table3-8. From the survey, it was found that the proportion of cars coming in and out of the project site through SukhumvitRoad is 3.3 percentcompares to the total numbersof vehicleson Na Krom Road, the majorityof whichare motorcycles(1.4 percent). The hoursbetween 8.00 - 9.00, the proportionof vehiclescoming in and out of the projectsite is only 0.8 percent comparingSukhumvit as a whole. Most were sedans, pick-up trucks and jeeps (0.5 percent).The numbersof cars usingNa KromRoad is 3.3 percenthigher than those using SukhumvitRoad when comparingthe total numbersof car on Na Krom Road. Again, most are motorcycles(1.4 percent). From 12.00 -13.00, the proportionof vehiclescoming in and out of the project site is 1.6 percentwhen comparingthe numbersof car on SukhumvitRoad as a whole and 3.5 percent whencompared with the numbersof car on Na KromRoad, mostof which are sedans,pick-up trucks andjeeps. W < Wfi~~~~~~~~q%SI ~~ / |Lq U - / ow Bf~~TTAR kJ ! I'~~~~~~~~~~~~~~~~O Figure.3-9-001 p~~oc ANetok rudN:( rjctAe Betweenthe hours of 16.00- 17.00,the proportionof vehiclesentering and leavingthe project site is 1.9 percent comparedto the numbers of cars on SukhumvitRoad as a whole and 1.9 percent when comparingwith the numbers of vehicleson Na Krom Road which are mainly sedans, pick-up trucks andjeeps. Obviously,the results of the survey indicate that the proportion of vehicles entering and leaving the project site is much lower than vehicles traveling on Sukhumvit and Na Krom roads. Also, a higherproportion of vehiclesuses Na Krom Road to get to the project site than SukhumvitRoad. When traffic density is to be converted to passenger car unit (PCU) for the purpose of calculatingtraffic peak volume capacity,as shown in Table 3-1, with a standard value of V/C ratio or a value which displaysthe levelof trafficthat each road could bear per lane per hour as follows: V/C < 0.7 meaningthe level of traffic is much lowerthan the roads' capacity; V/C between 0.7 - 1.0 meaningthere is a slight level of traffic and the roads are not being used to their fillest capacity; * V/C between 1.01 - 1.5 meaningthe levelof of trafficis very closed to the roads capacity, V/C > 1.5 meaningthe level of traffic congestionis very high and the roads are being put to used to their fullestcapacity. From the calculation,it was found that the survey points on Sukhumvitand Na Krom roads which are the two main access to the project site, have a VIC ratios of 1.04 and 0.9 respectively.This shows that the levelof traffic on Sulcurrvit Road is very closed to the road capacityand the level of traffic on Na Krom Road is very slight and the road is not being put into its fullestuse. Basically,the majority of vehicles entering and leavingthe project site are sedans, pick-up trucks and jeeps. There are only a couple of trucks and motorcyc]es.When converting,the value of PCU fbr the numbers of vehicle entering and leaving the project site throueh Sukhumvit Road, there are approximately 142 vehicles per day and about 174 vehicles per day on Na Krom Road. Importantly, the expansion of refineryunit 2's production capacitv would not in any way substantiallyincrease the transportingof raw materialsand products throughthe use of trucks. (B) Water Transportation Beside travelingby automobiles,trucks and motorcycles,the project site could also be easily reached by water transportation.This type of transportationis the heart for transportingof products and raw materials.The Chao Phraya River is the main river used for transportation and transferingof goods withinthe country. it also plays a noteworthypart in the public's everydaylife. 3.4.3 Draining System and Flood Control (A) Project Area The project site is situated along the plain on the estuary of the Chao PhrayaRiver where land on the eastern side is mainlyused for industrialand commercialpurposes while the western side is used for agriculture.

The important ones are Prakanong canal, Jek canal, Bangchak canal, Bang Oh canal and Bangna canal. Watergates and pumps control the draining of water. Table 3-12 illustrates the total numbers and the capacity of pumps. Prakanong canal which is the largest canal within the area drains water into the Chao Phraya River 24 hours a day by pumping water out when the watergate is closed. During a crisis, Bangehak canal Jelk canal, Bang Oh cana and Bangna canal would maintain the water level in the canals at 34.50 meters (the normal sea level is 35.03 meters). In case when the level of water in the Chao Phraya River is lower than the water level in these canals, water in the canals would be drain into the river by leaving the watergates opened. On the contrary, if the water level in the river is higher than the level in the canals, watergates would be closed and water would be drained into the river with pumps. During the dry season when there is not much water, watergates would be opened to receive water from the river, at the same time, drain water in the canals into the river as a way to change the water quality. During the rainy season, water in the canals would always be maintained at a constant low level. High and low tide system is used to drain water in the area on the western end. Several important canals are: ong Pae canal, Rua-bin canal, Yai-ed canal and Wat Bang-nam-pueng canal. Usually, in the area known as Bang Kra Chao is flooded everyday during the time when the tide is high for approximately2 -3 hours. The water would be drained auto-matically when the tide is low. During the rainy season when sea level rises and water from the north flows into the city, that particular area would be flooded for long periods of time. The Department of Public Works is presently in the stage of conductiAnga research on the means to control the problems of flood in such area. (B) WharfAreas Draining on each wharf is done by means of the slope of the wharf and through drain channel in the curb area down into the Chao Phraya River (only wharfs Nos. I SA and I SD, see Figure 3-10) Elsewhere, water is drained into a slop tank and there is a slap slopirg to the back side of the whar( draining it into an empty space of the wharf area so that it will permeate through earth. The wharfs using this manner of draining are Wharfs Nos. 18B, 18C, 1SF and Wharf No. 18E. As regards draining inl the wharf areas, it is done by means of the permeation of rain water through earth to dry automatically. This will help the absorption of oil that may adulterate in the wharf areas, keeping it from getting into the Chao Phraya River directly, but there may be some obstacles. In case of heavy rain, slow draining may lead to flooding from part to part in the wharf areas. The officials in charge of the wharfs would provide pumps to drain water into the public draining channels on Na Krom Road from time to time. With respect to prevention of floods in the wharf areas, presently throughout the front lines of the wharfs of Bangohak Refinery concret3 embanlanents have been built to prevent floods and erosion. There are walcways on the ridges of the embankments raised about 50 centimeter from the ground level, about 1 meter wide and running throughout the whole lengths of the whars, while the respective wharfs would be from +1.46 meter to +184 meter above mean sea level. 3.4.4 RFzterSources The survey conducted at governmental agencies located within one kilometer radius around the refinery, indicates that consumption water sources are city water (68.52%). underground water (16 .67 /o), water from rivers and canals (5.56%). rain water (3.70%) and water from other sources (5.550 /a). Potable water sources. on the other hand, come mainly from city water (53.85%). The rest comes from bottle water (lS S0%). underground water ( 1.9S%). rain water (6 92%) and water from other sources (345%).

Portable water in the area comes from rain water (90.00%) and undergroundwater (10.00%)(see more detail in Table 3-13). In Bangkok, consumption water has several problemssuch as brackish (33.33%), odorous (26.67%),hazy (20.00%) and it has leesand a rusty color (20.00%).Fortunately, the people in Bangkok City do not have to face the problemof water shortageswhereas undergroundwater is usuallyinadequate during the dry seasonand city water suppliedduring rush hours (6.00 - 8.00 am) does not have a constant flow. Similar to consumption water, potable water faces certainproblems most of which are that it has taste ofchlorine (43.48%), hazy (391 3%/o)and it has lees (17.39%o).Again, there is not problemin terms of the quantity. The problems of the quality of consumptionwater in Amphur Prapadaeng are: haziness brackish and odorous. Except during the dry season, there is sufficientamount of water for consumptionthroughout the rest of the year. As for potablewater, the persistingproblems are: the taste, the brackishness,sand and lees and nrst Similarly,water is scarce during the dry season. Communityleaders try to solvethe problemof insufficientconsumption water during the dry season by diggingmore wells.The lack of potablewater is alleviatedwith botte water. Water for agriculturaluses, on the contrary,comes from the rivers and the canals which has the capacity to serve farmers all year long. A few problems such as the problem of bracldshnessand the problem of oil stains mixed with the water, create anno-yance to localities. Unlike bottle water, the quality of potablewater is improved before the actual drinkingby using filtersor strainers, by boiling aftersedimentation. 3.5 QUALllY OF LIFE VALUES 3.5.1 Economic andSocial Conditions and Perspective (1) Boundaryand the Study Area (A) The Boundary of the StudyArea Surveyswere conducted in a prospectivearea whichis anticipatedto be affected by the Plant 2 ExpansionProject The two most likelyareas were located approximately2 kilometers away from the project (see Figure 3-11): * The Bangkok City area namelyBangna district, Bangchak district, Prakanong district Klong Toey distict, SuanLuang districtand Pravetdistrict. * The Pra Pa Daeng area in SamutPrakarn Province specificallyin Tambol Bang-kor-bua and TambolBang-nam-pueng. (B) The Scope of the Content Interviews relating to the issues of the economic and social conditions in the above mentioned areas have been conducted on communityleaders and governmental officials who lived approximately2 kilometersaway from the projectsite. The purpose of these interviewsis to inquire about educated people'sperspectives on the project in order to compare them with the impactof the project on the local population. xj~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~- IaC_ 2 ~~~~~~~~~~~~~~~~IBD 1 a Krom Rtoad Whar f S Location I.'

It is also importantto notice that the surveyshave been conductedon 10 percentof governmentalofficials who actuallylive in the area closedto the project site. (2) Economicand SocialConditions (A) Banzna district, Bangchak district, Prakanongdistrict and Suan Luang district retain a "city1 ' characteristiccomposing of residentialareas, commercialareas, industrialareas and several governmental agencies. Today, industrial and commercial activities have grown abundantlyin these areas. The nmber of populationin each district are: 94,506 people in Bangna district, 101,659people in Bangchakdistrict, 79,249 people in Prakanongdistrict and 95,515 people in Suan Luang district. The majorityof the population are of worling- age. Most are employed in companies and factories, have a private buslness, work for state enterprises and work fbr the governmentrespectively. The average income ranges between 10,000-40,000Baht per year. These characteristics,however, differ from those in Tambol Banko.k-Bua and TambolBang-nam-pueng. (B) TamnbolBangkok-Bua and TambolBang-nam-pueng which is located in AmphurPra-pa- daern, Samut Prakarn Province, in contrast to the other districts, are more of a 'rural community" The governingstnucture of TambolBangkok-Bua was dividedinto 13 villagesall of which are being overseenby the Organizationof ProvincialAdministration. The total population is 7.4:5. The total area is 2,768 rai (4.42 square kilometers).The populationdensity is 1,680 people per I square meter. Mlost.villagersare betweenthe ages of 18 -50 years old or 343 per cent of the total population.The seconddominant age group is between 14 - WV I I ,~~~~~~~~~~~L. -, ..

The majority of the people have completed at least elementary or secondary school. The villages are neither rich nor poor. - Formerly, almost everybody eam their living with agriculturing. However, due to the impact of sea water, planting fields would be flooded for 7-8 months per year. Villagers have to build dams which in turn, increased their production cost. For this reason, many left their fields and seek employment in factories, governmental agencies and state enterprises outside their villages. Nonethe-less, thie total area in Tambol Bangkok-Bua is 2,768 rai. Of this total land, 2,055 rai or 74 percent of the total land was alloted to agricultring. There are 455 households most of which are structured in the form of half rice filed and half garden. Tambol Bang-Nam-Pueng divided its governing structure imo I 1 villages. The total land in Tambol Bang-nam-pueng is 2,968.75 rai (4.75 square meters) of which 1,672 rai is used for agriculturing. Out of the 777 households, 310 households are owned by fanners. 2,848 people or 72.7 percent of the total population of 3,918 are between the ages of 18 -50. These are middle to upper income fimiiGeswho are govermnental and state enterprises employees, fictories workers and firmers. Orginally, the majority of the people lived on income from agricultuing. Today, many work in factories, governxnental agencies and state enterprises, leaving their fields abandoned and decreasing the agriculturing workforce. The reason is similar to the sitation in Bangkok-Bua- Flood was the major problem. Farmers had to spend a lot of money investing in dams which was not cost effective compared to their produce sold. (3) Views and Perspective on the Project Surveys and interviews conducted on sample groupswithin the study area depict these people's views and perspective concerning the project as follows: (A) In the past, 51.6 percent of the sample group was disturbed by the activities of Bangchak refinery. 19.3 percent was disturbed by the smell of oil, 14.6 percent by the smoke, 5.2 percent was concerned that they would be affected by accidents which might occur form the refinery. 12.5 percent was concemed by other reasons. (3) From the survey conducted on the same sample group, there were 36.6 percent in the sample group was disturbed by the project 8.0 percent was disturbed by the smell of oil, occasionally but such smell was not strong. 28.6 percent was concerned that accident would occur due to various reasons (note: the reason that a lot of people was concerned with accidental fire is because the survey was conducted during the time which a tragic accident had just occured - a LPG tank truck exploded on the New Petchburi Road). Evidently, the results of the survey show that the level of disturbances which the people and institutions located around the project site used to have relating to the activities of Bangchak refinery have decreased, particularly for the direct disturbances such as smell of oil and smoke. (C) Views and Perspective which the sample group has on Bangehak Refinery: -13percent felt that Bangchak refinery does not benefit anybody. 79.50 percent felt that the refinery is very beneficial. 7.5 percent showvedno idea or comment. For the people who recognized the refinery as being beneficialgave the following reasons: ;36.0percent felt that it creates employment and stable income and raise the level of the country's economv * 27.5 percentfelt that the refineryin beneficialto other industries. . 19 percentfelt that it helps createa balancein intemationaltrade. * 17.5 percentfelt that the refineryhelps develop and expandthe community. These given reasons demonstratethat the majorityof the people in the sample group regarded that Bangchakrefinery is advantageousto both the local and the nationallevel. (D) Interviews and surveys conducted on the sample group regarding their views and perspective on the impact of Bangchak refinery on the country's social and economic conditionscould be concludedas follows: 62.4 percentfelt that the refineryhas moreadvantages than disadvantages. 22.6 percent felt that the refinerycreates advantages as much as disadvantages. * 15 percent felt that the refineryhas more disadvantagesthan advantages. (E) The transportingof raw materiat productsand labor wouldhave an impact on both ground and water transportation and wouldaffect 34.4 percent of the livesof the people who lived in the area. The rest, 66.7 percent would not be affected.In the case where such transportation affectsthe local people, problemoccurs in terms of raw materialsand products transportation by vessels which had caused on oi spifl and troubled the houses along the nver. Ground transportationalso causedtrouble due to narrowstreet. (F) Being directly and indirectlydisturbed by the problemsrelated to the refinery'sactivities, the samplegroup has given severalsuggestions and preventivesolutions: * The refineryshould improvetheefficiency of its equipmentto get rid of the smellof oil, particularlyduring the transferingof oil and duringthe cold season. .Safetymeasures relating to accidentsuch as fire must be stnct and effectivebecause they have a considerable impact on the local's mentality. The refinery should provide informationand hold campaignsabout the productionprocesses and safety measuresbeing undertaken in the refineryto promote clear understandingamong the local people. This could eventuallydecrease the public'sconcerns. * Procedures in trasferringoil and gas and in getting rid of oil stain should be stan-dardized and secured. * Trucks used in trasporting raw materialsand finished products should be arranged to depart the refineryat specifictime in order to avoid trafficjam duringrush hour. * Ard Narong Road which is in front of the reinery should be expanded and rail tran- sportation should be used more frequently. (G) 63.4 percent of the samplegroup agreed that the refineryshould increase its capacityby revamnpinits Plant 2. Only 25.8 percentdisagreed with the project,while 10.8 percent did not expresstheir opinions. For those who agreed with the projectgave the followingsuggestions: a The refineryshould well plan its ground transportaionin order not to increasetraffic jam. * Regularmonitoring should be carriedout for trucks and transportingfacilities. Considered that Bangchak refinery is installing pipe lines to transfer oil from Bangehak- to Don Muang, this could help lessen trafficjam tremendously. 3.4.2 PAblic Health (1) Public Health Center Several health centers located within Amphur Pra-pa-daeng are: Bang-kra-chao Health Center, Bang-nam-pueng Health Center and Bang-kor-bua Health Center. Those located in the vicinity of Bangkok are: Pralanong District Health Center, Pravet District Health Center and Klong Toey District Health Center. Table 3-16 shows a list of health centers operated by the government, the private sector and by the Public Health Service Center. Beside health centers mentioned above, local people also prefer services provided by other health centers not in the survey, of which are both governmental and privately own as shown in Table 3-17. (2) Medical and Public Health Personnel Table 3-18 provides detail on medical and public health personnel active in three health centers located in Amphur Pra-pa-daeng. Table 3-19 gives information on medical and public health personnel working in hospitals and certain private health centers in the surveys which are located in Bangkok City. (3) Admitted Patienti Statistic Interviews with local people who lived in the area being surveyed indicate that when ill, most prefer to be treated at health centers located closed to their residents and at public health centers and hospitals in Bangkok Tables 3-20, 3-21 and 3-22 Illustrate that between 1989-1987, the statistic of out-patients used to be admitted in the three health centers were RI due mainly from respirtory related diseases (although the symptoms were not very clear), from accidents, from poisonous substances, from skin diseases, from infectious diseases and from worn related diseases. 1984-1989 statistics show the percentage of patients in all three health centers admitted because of respiratory related diseases which is the number one cause of illness in all three districts as follows: Health Centers 1984- 19 t 1986 1987 -1988 1989 Bang-kra-chao 39.54 44.85 44.18 44.85 38.29 43.73 Bang-namn-pueng 47.82 37.94 41.78 41.08 40.32 50.12 Bang-kor-bua 41.81 38.93 44.95 50.45 42.93 (Data betweenyears 1984 - 1985 was providedby SEATECCompany Ltd.) Evidently, the statistics illustrate that when compare respiratory related diseases within a six year period, the percentage of patients admitted does not vary substantially within the district and berween the districts. Table 3-23 displays data relating to patients who were admitted at the nine health centers and only those who were admitted for respiratory diseases from 1987 - 1984 Table 3-16 Health Center in the District of Prakanong, Pravet and Klong Toey Health Center Number of Beds Govermental Hospital Naval Ordnance Department 60 Port Authority of Thailand Hospital 30 Private HospitaYl-ealth Center Smitivat Hospital 20(i Bumrungrad Hospiial 200 Kuaynumtai Hospital 150 Sukhumvit Hospital 110 Camilian Hospital 100 Prommit Hospital 80 Bangna-Trad Hospital 50 Padpunya Hospital 46 Rittanin Eye Clinic 25 Pattanavat Hospital 25 Navapad Polyclinic 10 21/491 10 Choice Nursing Home Co., Ltd. 10 Theptarin Hospital 8 Rumchat Polyclinic 50 Rita Polyclinic 2 Public Health Center Public Health Center 8 Public Health Center 10 Public Health Center 21 Public Health Center 22 Public Health Center 32 Public Health Center 34 Public Health Center 37 Public Health Center 41 Public Health Center 57 Table3-17 leialthiCenter in Banglkokand their Services, 1988 Number Number Numberof first-time-servicePatient Numberof Service Numberof Stay-at- of Places ofBeds Outpatient Inpatient Other Outpatient Other Hospitalof Inpatient LypicalServices Government Ministry of public health 5 2,756 246,566 65,088 49,859 1,273,180 218,198 754,273 Otlier ministry 12 4,587 487,523 55,228 78,094 1,742,371 220,957 840,803 Ministryof Llniversityaffairs 2 2,798 222,801 83,036 - 1,842,596 9,774 229,616 State enterprises 5 558 31,581 4,464 18,515 240,334 21,042 82,513 Municipality 6 1,992 755,872 63,976 83,398 2,348,836 585,548 394,447 Private 59 4,812 1,234,494 115,387 81,664 1,183,071 192,788 649,748 independentorganization 2 1,298 239,351 39,538 256,017 790,498 790,704 337,056 SpeciricServices Government Ministryof publicliealtl 7 2,325 98,754 13,156 - 436,510 - 495,821 Mlinistryof universityaffairs 1 220 10,679 1,727 - 31,665 23,761 57,329 Private 17 339 86,298 8,524 23,258 115,979 338,692 47,060 Table 3-18 Miedicaland Puiblic Hlenith Personnel of Bangkoli and Pra-pra-daeng District -______,______Unit:person ______~~~~Numberof Personnel ______1lealtil Ceniter Doctor ______Dentist Pliarmacist Nurseand Assistant Assistant DentalHealth ______Midwife Dentist Pbarrnacist Office fBang-kra-chao IlealthCenter - 3 B3ang-nam-pueng HeafithCenter 3 Bang-kor-btia1ealtlh Centcr - - 4 PrivateHIospital/Helith center 47 - 14 120 - - IPliblicHlealth Center 18 9 9 108 9 9 9 Table 3-19 Classification of Medical and Public Health Personnel in Bangkok, 1988 Type of Profession Minisay of Other State Municipality Private Independent Total Public Health Ministry Enterprises Organization 1.

OccupationalHeathandSafety (1) Air Quality in the Workplace Air qualitywas assessedin refineryPlant 3. Several substanceswere evaluated,specifically the level of CO, HES, NO.,, SO2, SPM, 1,1,1-Trichloroedhaneand organic lead compound.There substances were analyzed by the Faculty of Engineering,Chulalongkorn Univeristy. The results of the assessmentare demonstratedin Table 3-24. (2) -NoisePollution Normally noise evaluationwas conducted only in refineryPlant 3 when the plant was in operation. Several places withinthe refinerywhich were deemed to be sources of disturbing noises had been designatedas the samplingstations, namely,areas next to machines'motors, areas by the operatingpumps and the maintenanceunit. Noises resultingfrom the activitiesand operationsof the refinerywere heard continuously.Evaluation relating to the level of noise in the workplace was done by a group of experts from Aggie Consult Company Limited.The followingdetail has been provided: (A) Distances in Measuringthe Levelof Noise Equipment used in measuring and testing noise density from each source was a noise measunng machine set up by using a 1.5 meter camera stand (Image 3-2). The machine represented a refinery worker within a hearing zone distance. The level of noise was also measured in places where workers were actually present by setting up a noise measuring machinein an opened area away from the sources of noise together with a noise rebounding wall withinthe radius of 3.0 meters.This could eliminateany unwantednoise 7-c-c*: -. (B) The Trimig of Each Measurement Since the majority of the sources which produce a lot of noise are mo:ors gcnr:_.:;.n steadv noise, the level of noise were measuredfive minutestwice consecutivelyfor each source The level of noise was recorded every minute. Leq. was then calculated according to safeny standard(for the level of noise)in the workplaceregulated by the Departmentof Labor, The Ministryof Interior. Noise levelis alwaysbeing measuredwhen the machinesare in operation. (C) Equipmentused to MeasureNoise Level A Sound Level NMetter,prod-ced by Bruel and Kjaer, Model 2226, was the main equipment used to measure the level of noise within the refinery. This equipment complies with the product standard set by the InternationalElectrotechnical Commission (IEC) type2.Before the equipment was put to use, it was tested for precision with a precision testing machine.In addition, during the operating of this equipment, a wind screen was utilized in order to decrease the impact on the environmentsuch as suspendedparticulate matters, etc. aroundthe area.

Oilywaste waters are collectedin an oily water pond and cycled through a conrugatedplate separator (CPI) and then dissolvedair flotation(DAF). Tankdrains are sent throughoi separatorsand the oilywater is sent to the oiy water pond for physicalseparation at the beginningof the waste water treatment process. Sour water and spent caustic are combined in an equaliztion tank and sent to a tilted plate separator(TPI) and to the activated sludge process. The effluentfrom the dissolvedair flotation is also sent to the atvated sludge process. The activated sludge process consists of an aeration tank and a clarfier flocculator. The effluent from the clarifier is discharged Througha flow measurementflume. Estimed quantity and qualitiesof waste water from new process units are shownin Table4-3.

The studyin the model included sulfur dioxide (SO2 ), nitrogendioxide (NO 2 ) and particulates(TSP). A mathematical model wasused to calculatethe concentrationof emissionsat ground level coveringarea in the distanceof 10 km fromthe refinery. The mathematical model was acceptedby United StatesEnvironmental Protection Agency (US.EPA)to be used for calculationof concentrationof emissionsin the ambient. The softwareprogram used for the studywas UNAMAPVersion 6 which had been used sinceNovember 1985. The programconsists of 33 models for variouscharacteistics. The mathiematicalmodel used for the study was IndustrialSource ComplexShort-Term (ASCOTS) Model which is Advanced GaussianPlume Modeland is appropriatefor projectin the plain area. The basis for the calculationof dispersionis shownin Table4-4 The results of the studyare as follows: Sulfurdioxide (S02) In the existingrefinery, fuel gasesfrom Plant 2 and Plant 3 are sent to Fuel Gas AmineTreating Unit to remnovesulfur and then sent to fired heaters in Plant 2 and Plant 3 to be used as fuel. Anotherprocess which help reduce SO2 is SulphurRecovery Unit which can removehydrogen sulfur from acid gases up to 98% by weight. Therefore,emissions from heater stacks have low S0 2 than the standards. It was estimatedthat the total SO2 emission from the existing refinerywould be about 6.4 tons per day. Based on the calculationof S02 at 4-8 ground levelin every 1 squarekdlometer around the project site in the distance of 10 km., the results of the studyare as follows: The highestconcentration of S0 2 in 24-hourperiod was 59.53 micrograms per cubicmeter which was below the standardof 300 micrograms per cubic meterset by Thailand'sNational Environmental Board (NEB). The highestconcentration was foundat the distanceof 1.5 kilometernortheast of the refinery. The isoplethsin Figure 4-4 showsthat the concentrationof S02 is high in the northeastarea at the distanceof 1-2 kilometerfrom the refinery. The highestaverage concentration of S02 in 1-yearperiod was 13.23 microgramsper cubicmeter whichwas belowthe standardof 100 rmicrograms per cubicmeter for annualaverage. The highest concentrationwas found at the same locationas 24-hourperiod and is in the northeastarea of the refinery. The estimatedhighest concentration in each location is shown in Table 4-5. The isoplethsin Figure4-5 showsthat the dispersionof SO2 is in the northeast region of the refinery. The actualdata of ambientair qualityaround the existingrefinery are shown in Chapter2 and the highestaverage concentration of S02 is lower than 47 microgramper cubicmeter in 1-yearperiod. Nitrogendioxide (NO) The concentrationof NO2 was calculatedsame as SO2 and the results are as follows: The highestconcentration of NO2 in 1-hourperiod was 15.21 microgramsper cubicmeter whichwas below the standardof 320 micrograms per cubicmeter set by NEB. The highestconcentration was foundat the distance of 1.5 kilometernortheast of the refinery. The isoplethsin Figure 4-6 shows that the dispersionof N02 is highin the northeastregion of the refinery. The highestaverage concentratikr, of NO2 in 1-yearperiod was 0.80 microgramsper cubicmeter. Thoughthere is no standardfor N02 in Thailand, the highestconcentration was far below 1eL, microgram per cubicmeter which was the standardset by US.EPAfor 1-yearaverage. The isoplethsin Figure 4-7 shows that the dispersionof NO2 is not far from the refinery. 4-9 Map for overlay of dispersion model. l.x_- uu~~~~~~~~~~~~~ &-Z. -l ~~~~~~~~~~~~~ ..

The highest concentrationwas found at the distanceof 1.5 kilometernortheast of the refinery. The isoplethsin Figure 4-8 showsthat the dispersionof TSP is not wide as SO2 and N02 . The highestaverage concentration of TSP in i-year period was 3.91 microgramsper cubicmeter which was below standardof 100 microgramper cubicmeter set by NEB. The isoplethsin Figure4-9 shows that TSP was dispersedin a short distancefrom the refinery. In the new project whichincludes FCC unit, Flue Gas DesulphuizationUnit, Gas OI HDS unit, Fuel GasTreating Unit and Sulphur RecoveryUnit, it is estimatedthat there wouldbe total SO2 emissionof 5.9 tons per day based on sulfuircontent of 0.5% in reduced crude used for burning as shown in Table4-6 and Table4-7. Dispersionmodel of the refineryincluding new racilitiesin the projectwil be performedwhen detaileddesign is available. 4.1.3 Solideffluents and spentcatalyst Solid effluent from FCC complex is presented in Table 4-8. Catalyst fine entrainedinto flue gas stream from Regenerator(Combustor) is presented as the total quantity. Almost all the amount of catalystfine will be caught upto FGD, and the solid is separatedwith filterpress. The rest of the catalyst fine is caught in Electrostatic precipitator (ESP) to meet Thai governmtenfs environmental 3V regulations. On the other hand, a catalystfine entrainedfrom Disengageris routed to FCC bottom product of HCO+SLO. The solid in the stream can be removed by Separator,e.g. GULFTRONICS,to lessthan 100wt-ppm. With respect to spent catalystfrom FCC unit whichwill be about 1 2 ton per day, the catalyst will be sent either to cement plant to produce concrete blocks or transportedto land fill.. 4-18 Table 4.6 Summary of gas effluents - from existing and new facilities - FCC/FGD/ESP Refineryfuels Total desulfurized burning flue gas flue gas flue gas Flowrate, Nm3/h 79,700 334,000 413,700 Composition S02, ppm-vol 310 191.2 214.1 N02, ppm-vol 600 N/A 96 CO, Vol% 0.05 0.00 0.01 C02, vol% 12.97 11.2 11.64 H20 vol% 18.78 11.9 13.22 02, vol% 1.62 2.6 2.41 N2, vol% 66.62 74.4 72.88 Total vol% 100.0 100.0 100.0 Note: N/A;not available Table4.7 Estimateon flue gas in burningrefinery fuels - Reducedcrude burning case - Refinery Refinery Refinery fuel oil fuel gas flue total Fuel Firingduty, mmkcal/hr 180 75 Sulfuircontent, wt% 255 0.5 0 Fluegas Fluegas rate, Nm3/hr 234,000 Fluegas composition 100,000 334,000 S02, ppm-vol 11.8 C02, 0 191.197 Vol% 12.5 H20, 7.8 11.2 vol% 9.4 02, 17.6 119 vol% 2.6 N2, 2.5 2.6 vol% 75.3 Total 72.0 74.4 vol% 100.0 100.0 100.0 * * ,!

Increasingtransporttion of products will be about 3,600 barrels per day LPG and 9,000barrels per day of gasolineand decreasing transportationof fuel oil by about 12,000barrels per day. LPG will be transportedby 700-tontankers and tanktrucks. Gasolinewill be mainly transportedby newly-installedpipeline to BCP tenninalin the north. Totally, the tansportation of products willbe decreasingafter the completionof new pipeline in mid 1994. 4.2.3 River water Increasingtransportation of LPG by tankeras well as cunrentloading and unloadingof crude and products at piersmight have impact to the river water, especiallyin case there is oil spillor accident. Oil dispersionmodeling in the riverin caseof spillwas performedin 1988 using mathematicalmodel taldng into account flow of river and tide. The scope of study coveredthe distanceof 12 km. fromthe pier which is 25 km. from the mouth of Chao Phya River as shownin Fifure 4-10. The modelingwas performedin 4 cases of spillvolume, 10- , 1, 100 and 5,000 cubic meter. The results of studyindicate that in one-dayperiod the minimumdispersion will be 15.4 knmor cover area of 6.05 squarekilometer and the maximumdispersion will be 28.2 Ikm.or cover area of 11.08square kllometer as shown in Table 4-9.

Blind flangesare bolted to the hoses when not in use. The manifoldsare equippedwith checkvalves. A perimeter ditch surroundsthe onshoremanifolds, and is lead to waste water treatment eystemSpill containmentbooms are deployedto encirclethe entire ship for each loadingoperation. Wamingsigns and the fireemergency plan are posted, and there is a wind sock at the controlroom. BCP has spill control equipmentmaintained at the control room which include25 drumsof freshwateroil dispersant, skimmerand suctionpipe for diaphragm pump, suction truck, absorbent,suction hose, backpackdispersant sprayers, portable dieseldriven sprayer, mobile wagon dispersantsprayer to be run off fire hydrantsystem, a workboat withboom spreaderand dispersantsprayer. Three spare oil contaiment boomsare kept at the ficiUity. Nevertheless,it has been recordedthat there is no accidentor oil spill at piers for years and accordingto monitoringdata of Chao Phya river qualityat the project area during 1-yearperiod, oil and grease contentwas in the range of 0.6- 2.8 mg(iter as shownin Table3-7. 42.4 Water Consumption Curntly, water consumptionin the refineryis about 5,500 m3/day for power plant and heat exchangein the processand for off-sites. Raw water is obtainedfrom underground through 5 wells These wells are 170- 200 meters deep. After the project is completed, the refinery will increase consumpton to about 7,200m3i/day. City water, on the other hand is being used at 250 m3/day. To improvethe qualityof deep-weUwater to be in used in the x boilers, an ion exchangesystem is applied.Chenicals are added to cooling water to adjustpH level and decreaseorganisms. 4.2.5 Enerav Consumption The refinerycurrently needs 15 MW of electricityand wil increaseto 23.4 MW after the project 17 MW will be generated in the refinery and the remaining requirement will be purchased from the Metropolitan Electricity Authority (MEA). A gas turbine generatorof 5 MW capacity will be installed in the project. 4-25 4.2.6 Drainageand FloodPrevention System The refineryimproved its drainage and flood preventionsystem in 1988. Water from vafious areas and rain water will be drained into a guard basin before dischargingto outside. Additionaloily surifacedrain from process units will be installedin the project Floodingis not anticipatedto occur within and outsidethe refinery'scompound. 4.2.7 OccupationalHealth and Safetv Currentlythe refineryis undertaldngprecaution activities in many areas such as industial healtb,safety, emergencyfire protection and prevention and oil spill preventionwhich details has been depictedin Chapter3. 4-26 Chapter 5 Environmental MitiEation Plan and Monitoring Plan 5.1 Mitigation Plan Bangchak revamped its refineryunit in 1987 and expandedthe refinery capacity in 1989.

Thisarea is classifiedas hazardousarea. iii) LightProduct Tank Areas Includingtank areas that containinglight products(flash point below 135°F) such as gasoline,kerosene and jet fiel. These areas are classifiedas hazardousareas. iv) UtilitvArea Includingarea of powerplant, steam generatorand boiler. This area is classifiedas intermediatehazardous area. v) HeavyProduct Tank Areas Includingtank- areas that containing heavy products (flash point higherthan 1350F) such as dieseland fuel oil. These areas are classi- fied as low hazardousareas. vi) OtherAr Including offlicebuilding, canteen, maintenance building, control room, laboratory,fire brigade and areas that are not classifiedin abovementionedareas. These areas are classifiedas low hazardous areas. b) Cause of Hazard in the Refinery i) Human Error: Hazardmay be caused by misoperation,negligence, misunderstandingand so on Table 6-1 shows details of human error. ii) Phvsical Error: Hazard may be caused deficiencyof material or equipment,corrosion, leakage, etc. as detailedin Table 6-2. c) SafetyEquipment i) Alarm System Alarm systemcurrently used in the refinery is DCS console which can warn of a risk by alarm display, graphic display and signal to operatinggroup display. ii) EmergencyrShutdownand InterlockSvstem This system is the cortrol system for safe emergency shutdown of the plant. It was installedboth in Plant No. 2 and Plant No. 3 which functionsas follows: a) Load SheddingSystem Electricityused in the refinery comes from 2 soures; refinery power plantand MetropolitanElectricity Authority. This system wiil measurethe electricityfrom the two sourves. If there is any failure of supply this control system will automaticallyshut down the planttemporarily. b) EmergencyPlant Shutdown In case of fireor emergency,Plant No. 2 and Plant No. 3 can be shut down simultaneouslyfrom the control room which has reservedpower supplyfor the control system. c) TPU CrudeCharre SelectionInterlock System There are 3 pumpsfor crude chargingto each plant, 2 in opera- tion and I for spare. The spare pump will automaticallystart worldngin caseof failurein any operatingpump. d) NPU OperationMode SelectionInterlock System The operationof NPU in Plant 2 and Plant 3 require hydrogen gas in a certain quantity. If there is any shortage of supply. this system will warn the operator by conventionalconsole in the control room Table 6-1 Causes to Human (Human Factor) Classification Detailed Example Classification OperationalError Mis-Operation - Valvemisoperation (Error Carelessness) - Error in operationprocedure (Error & negligenceof standard Operationprocedure) (Abnormalreaction, pressure, combustion) DangerousAction - Carelesshandling of dangerous -materials (Accumulation, spilled oil gushing& outflow,Oxidation Cracking) - Unsafe work (Carelessness use of unsafe tools) Incompletecheck - Deficientchecking before work - Deficient daily cheL.kind Poor Management Defects in Management - Lack of communication - Poor guidance by supervisor - Poor safety countermeasure before work Table 6-2 Causes Due to Materials(Physical Factor) Classification Detailed Example ______Classification InferiorMaintenance - Corrosionand/or errosion of materials - Clogging of equipment and/orpiping - Mechanical defects of - Leakage, Rupture, Break, of equipmentand/or Flanges,Gland, etc. instruments Defective - Poor material quality - Mis-Design Fabncation - Improperfabrication .,- Interior Design - Iferior design not - Lack ofKnow-How anticipatedat the time - Poor Considerationfrom of design SafetyStandpoint Outside - Raw materials - Supply of raw materials stopped Disturbance - Utiflities - Supply of electric power stopped - Supply of steam stopped - Air pressure drop - Coolin, water pressure drop Other - Fire Sources, Ignition - Static electricity, spark Sources spontaneouscombustion e) NPUFeed Cut System This systemcontrols feed charge rate of NPU to dialy set point capacityby emergencyvalves. f) F-101 ShutdownSystem This system will control operation of fired heater in TPU. In case of emergency,fuel charge systemof the heater will be cut off by emergencyvalves. g) F-I01 Off GasBuming Interlock System This system controlsthe separationof acid gas to bum at flare so that fuel gas can be used in the heater,otherwise fuel gas will cause corrosionin the heater. h) EmergencvValves of CRU Furnace To protect any accident of fuel supply to CRU fumace by stopping the furnace operation or shut down the fuel charge systea. i) SafetyValves of Pumpand TransferringSvstem - To control operationof pumps and products transferimngsystem to prevent any emergencyor accident. iil7 Pressure ReliefValves To control pressure of high pressure or gas related equipment. Pressure reliefvalves will work when there is any abnormalpressure. iv) Er .ergencyMotor OperatedValve Motor operated valve wil be installed in pipeline for feeds or products whichcan easiy evaporizeor have temperaturehigher than 260°C to protect any retention or build up of pressure. The motor operated valves are fireproof and their switch are kept at safe location. v) SnuffEngSteam for FiredHeater In case there is explosionor fire in heater, snuffing steam will be injectedto the fire to controlheater temperature. Since the heater is normallyoperated at high temperaturesnuffing steam facilitiesare installed15 meters away from the heater. vi) Safety Shower Safety showerwill be installedin processunit area and located in the followingunit A - Light Naphtha Merox Unit - LPG Caustic Washing Unit - LPG Merox Unit - Caustic Distribution System, etc- vii) Combustibleand ToxicGas Detector Svstem Combustibleand toxic gas detector systeminstalled are as follows: - LPG detector : to detect leakage of LPG from the area such as LPG sphere area and LPG pump at LPG meroxunit. - Toxic gas detector: to detect toxic gas such as hydrogensulfide in the area of fuelgas treatmentunit, sulfur recoveryunit and gas oil hydrotreatingunit. 6.2 Hazard and Onerabiitv Study 6.2.1 Introduction In the refnery, safety equipmentor facilitiesfor monitoringof the operation and/or any irregularityare installedas follows: - Fail-Safe: to check operationof equipment.If the operation deviatesfrom the set point or fails, the back-up system which is called fhil-safe will operate immediately.Fail-safe will work in the followingsituation: * failure of air systemor powersystem - falt of control signalof equipment * failure of temperaturemeasurement Basically,fail-safe system are designedfor equipmentand facilities in the refinery. 6.22 Alarms Alarmsystem will warn the operatorswhen the operationof the process unit deviates from the set points such as temperature,pressure, level and flow rate. The set points willbe establishedfrom the limitationof each process unit. For example,as a process unit whichis operated at temperatureof 2000C, the set point for operatingrange will be set at 150°Cand 2500C. The temperature control systemvwill adjust the operationwithin this range. However, if this control systemfails, the alarm systemwill work immediately. In Bangchak Refinery,there are two kinds of alarms,alarm by siren and indicating ight in the control room. Moreover, there are alarm system for vibration of rotating machincs especiallypumps, compressors,fans and steamturbines generator. The alarm system will work-when the vibrationof the machines is abnormal. 6±3. Remote Emeryencv Shutdown System In case of emergency, the process unit will be shutdown. The basic concept of emergency shutdown is to cut off all power distribution system, reduce quickly temperature of the unit as low as possible, and reduce fuel in the system. Remote shutdown system which is operated at control room are as folows: a) Remote Shutdown of Heaters This is the first step for emergency shutdown in the control room. Fuel supply will be reduced and snuffing steam will be injected to prevent fire. b) Remote Stop of Pumps and Comnressors When the heater stops working, pumps and compressors will be shut off in the control room. 6.2.4 Flammable Gas Detectors The detectors will detect flammable gas and chemicals or hydrocarbon. The detectors are installed in the following area: - high pressure process unit - around fired heaters' - connection of equipment There are 2 Idnds of detector. The first ldnd is to deteca gas in high pressure process unit and around fired heaters at which alarm levelis set at 500 vol. ppm., the second kind is to detect gas at specific area at which alarm level is set at 0.45 vol.%. 6.2.5 Backup Svstem for Instument Air and Electricitv In case power failure or instrument air supply failure. this s. s:e-. A,!: supplv for a period of time during which the failure will be rene.d:ed In case of nitrogen supply pressure (normally at 6.5 kIgcrn2g) for gas oil hydrotreating unit which is operated at high pressure is inadequate, the backup system will increase pressure to the unit within 20 minutes. Similarly, in case of power supply failure, all the process unit will be emergency shutdown and power back up system will be utilized. The power backup system is supplied from battery which can supply power to the unit for 20 minute and to the control room for all the time. This power back up system is called "CVCF". 6.2.6 Pressure Relief Svstem This system will prevent equipment from higher pressure than normal. Function of this svstem can be described as follows: - Safetv Valve and Relief Valve These valves are operated by on-off spring according to pressure. Normal position of valves are closed. But if pressure is increased to the set pressure, valves will be automaticallyopened. Safety valves will be used for gases; on the other hand, reliefvalves will be used flor liquid. Normally, relief valves for toxic liquid will be connected to receiving storage for dischargedtoxic liquid. But for nox-toxic liquid or water, liquid will be drainedto surface. Safety valves will releasedgas to stack or flare. 6.2.7 Rupture Disk Rupture disk is a thin diaphragmequipped to flanges to reduce pressure Rupture disk is normallyused for equipmentwhich pressure can be increased rapidly wheresafety valve and reliefvalve is not applicable. 6.3 Risk Assessment Area in the refinerycan be classifiedaccording to risk as follows: 63.1 LPG Sphere There are 2 iypes of LPG storage in the refinery. One is bullet and the other is sphreretank. There are 6 bulletsof capacity185 millionliters (50 MTON) each numberedD-91 1, D-912, D-913, D-914, D-915 and D-916. There are 2 spheres of capacity1,830 nilion iiters(1,043 MTON) each numberedT- 950 and T-974. Normally,LPG willbe stored in sphere. Bullets will be used for temporary storage of LPG which will be transferred to sphere. Risk assessmentwas performedfor sphereas foLows: a). OperatingLimit ofLPG Sphere The highest level of LPG in the sphere will not be more than 11.40 meters (800/a of sphere capacity),therefore maximumcapacity of sphere is 1,464 millionlter (834.4 MION).

Note In case of any leakage,the control system of LPG sphere will releaseLPG to flare,quantity of LPG and pressureof spherewill be tremendouslydecreased and consequently decrease the value of L. c) Risk Assessment LPG sphere in the refineryhas a completesafety control measure such as safety valve, cooling water system, gas detector, remote block valve, leveland pressurecontrol, etc. In an emergencysituation, a safety valve will releasegas to preventexplosion. Cooling water will be automatically dispersedto cool down the sphere. A gas detector will signal to the control room. In addition,a remote block valve which is located 15 meters away fromthe tankwili cut offthe flow of gas. Furthermore,LPG is controlledto contain RVP at lower than 100 psi which is less than standardregulated by the Ministryof Commerce(140 psi) and is probablylower than other refineriesin general. Whereas BangchaklsLPG sphere aloawableworking pressure is 250 psi. It &is- certainthat accidentsuch as fire or explosionis improbable. In the worst situation,if LPG sphere explodes or catch fire, building structurewithin a 44 metersrange willbe damaged;building components within an 89 meters range wil be damaged; and people within a 487 meters range will be affectedas shown in Table 6-3 and Figure 6-2. If there is fire or explosion,it will impact structure, buildingcomponents and people at the distanceof 615, 1,065and 1,885meters respectively. Nonetheless,it is the least likelythat LPG sphere will explodeor catch fire becausethe refineryhas measuresas follows: i) SphereDesign To get maxinum safety,the refineryhad taken into account LPG sphere designas follows: - Safety valves are equippedon spheres and bullets which shal releaseLPG if there is fire. - Cooling water system. In case of fire, cooling water will be sprayedto the surfaceof sphere to protect deformationof metal and prevent explosion. - Gas detectors wvilsignal to the control room if there is any gas leakage.

In additionsthe refineryhas safety committeeand safety teams to reviewand monitorsafety conditons in the worling place. 6.3.2. Crude Tanks Presently,there are 14 crude tanks 5i the refineryof capacityfrom 90,500- 350,000 barrels. Risk assessmentwas performedfor crude tank capacity 350,000barrels. According the followingcalculation, the radiusof fire will be about 166 meters as shownin Table 6-4 and Figure 6-3. - RadiationEffect qp = 0.0012R (LHV2) A PT I (L 2) qp = Spill(pool) fire radiant heat flux,Btu/hr.ft 2 LHV = net heat of combustionfor the material,BtuAb A = surfacearea of the fuelpooL ft 2 PL = .

However, preventionand control of fire had been taken into account in the designand operationas follows: a) 2 sets of levelalarm instrumentwere installedindependently at two levels. If level of crude goes higher than the set levels, the instru- ment will alarmto the control room. In addition,foam line systemare installedon crude tank-s:tank seals and roofs have been regularly inspectedto preventany leak-azeof vapor.

Risk assessmentwas performedfor 200,000-barreltank. Accroding to the followingcalculation, the radius of fire is about 55 meters as shown in Table 6-5 and Figure 6-4. - RadiationEffect qp = 0.00 12R P AP/ (,L) 95% gasolineintak L = (O.0012)(O.3) (19000) O3.38L.50) L44.93) (155) (3962.5) = 32148.04 L = 179.30= 54.65m. To prevent the hazard, the refineryhas measuresas follows: i) Floatingroof tanls are used for gasoline. ii) Fire fightingsystem and fire extinguishersare equipped around tank storage area. iii) Coolingwater will besprayedif there is any fire. iv) Operatorshave been trainedwith respect to operationsand safetv. v) Other safetymeasures are similarto crude tanks. 6.3.4 Gas Oil HIDSUnit. Fuel Gas Treatment Unit and Sulfur Recoverv Unit Risk assessmentwas perfonned for each unit. Calculationof impact in case of fire using "Jet Fire" calculationand dispersionof hydrogensulfide if there is any leakageusing "PlumeModel" was performed. Results of the study are as follows: a) Gas Oil HDS Unit In case there is a fire in this unit, heat flux of 12 KW/m2 or about 4,000 BTUthr-ft will cover the distanceof 29 meters which will onlyaffect the nearby process unit. In case of hydrogensulfide leakage, the maximum concentration at ground level will be about 5.67 x 103oppm at the distance of 196 meters.

In case of hydrogen sulfide leakage, the maximumconcentration at ground level wil be about 1.27 x 1O ppm. and will flow to a distanceof about 87 meters. c) SulfurRecoverv TJnit The dispersionstudy of hydrogen sulfidefrom SRU was perfonned by plume model. The result indicates that if there is any leakage of hydrogen sulfide, the maximum concentrationat ground level will be - about 525.3 ppm at the distance of 132 meters from the source of leakage. 6.3.5 Preventive Measures To Prevent fire and dispersion of gas, the following measures had been considered: a) Desisn of ProcessUnit In the process units, safety valves are installedto control temperature and pressureand to cut off flow or releasepressure. b) Fire Fightingand Foam Pipeline Fire fightingfacilities are instaUlledin the nearby area and available for immediateuse. c) Gas Detectors Gas detectors are installedat the area where there is potential of risk. d) Trainiinzof Personnel Operators havebeen trainedfor safe operationand safetvpractices. 6.3.6 Mitioation Measure Bangchaklrefinery has prepared Accident PreventionPlan for the refinery includingthe pier area. The plan is composedof 3 main plans as foUows: 1. Emergencyplan 2. Coordinationand co-operationplan with other organization. 3.

Last yearat Bangchak,100 percentofthe employeeshad firefightingtraining. 7.3.3 Supemsionof Work-Permits Four kindsof work permitsare issuedto contractorsat BangchakRefinery 1) cold work, 2) hot work, 3) vessel entry, 4) X-Ray. Each work pennit is searated into categories. A checklistand attachments are providedfor each category.The work permitsare preparedby the field engineerand che&edand acceptedby the area supervisors.Ilspections and audits are carriedout by the Safey PromotionTeam and SafetyForemen to countercheckthe area authority. If unsafeconditions are uncovered,work is stoppedimmediarely. Each permitis good for only 8 hours of work. Work commencedon holidaysand at niguh requires special considerationby the operation learn because the support functionsare not availableat the refinery. Therefore,this type of work permitis avoided when possible or special precautions are taken after review by management Contractorsare requiredto havesafety officers or safetyengineers to counter controlwith Bangchak safety engineers. 7.3.4 ContingencvPlans The BangchakRefinery Contingency Plan has been revised and reviewedand updatedtwice this year. The ContingencyPlan is regularlyupdated only once per year. A meetingfor orientationof supervisorsis calledon contingencydrils, once each year. BCP employeesare given fire trainingand havecompleted the highestlevel of trainingby a U.S. epert consultantcourse given in Thailand.Six drils per year and classesand drillsin respirators,firefighting technique are given to Bangchak employees.Safety teams conduct safety equipment checks, inmcludingfoam, floatingtardc seals, etc. besidesthe firefihtng equipmentitselE The Safety Engineercoordinates compliance with new Thailandsafety laws. Saferyposters and safetyawards are part of the safetymanagement technique. 7-6 7.3.5 FtreSuplression Svstems The fire suppression system design was checked by Japanese and British petroleum experts and modified according eo their recommnendauons.The standardsused in the firesuppression system are the NFPAor better. Fire water for the fire suppressionsystemn is obtainedfrom the river through redundantpumps, both electricand diesel. Thereare three main fire water lines. Thepressure in the line is automaticallycontrolled and set by jockey pumps. The jockey pumps are all electic. The firewater pumps can be operated by the control roonmremotely. The large firewaterpumps are both diesel and electric. In addition,the facity maintainsseveral fire trucks, one foam truck two large fire trucks, and two small fire trucks, plus an ambulance. Bangchak has recently placed an order for a telescopingplatform and rescue truck. The order is expected to be filled within 10 months. The order would include rescue equipment. 7.3.6 Tnnk1ann The LPG spheresare equippedwith water delugesystems. In addition,the tak rm is equipped witha foam chamberand a foamtruck. Hydrantsfor foam and water and fire monitorsare locatedthroughout the plantand tank farm. All of the bulkstorage tanks are surroundedby dikeswith ipervious (plasticliners topped with asphalt)bases. The dikes surroundingthe legt fuels have recently been raisedin order to containthe fill volume of the enclosedtanks. 7.3.7 Sft neerin The control room of the Bangchak Reflneryincludes a fire alarm system and automatic feed cutoffs for the processing units. The fire alarm system is displayedon a site plan board and includes both fire alarms and gas leak detectors.The firepumps are automaticallystarted and the systemcan be started from the control room as well. The systemis checkedonce each week. The controlroom itself is an explosionproof bulding, and is protected with a halon fire protectionsystem. A computerizedcontrol system in the refineryoperations control room allowsfor automaticshutdown of individualunit feeds and unit process operationsin the entire plant. Video monitors in the control room are tied to video cameras located throughoutthe plam The monitorsare normallyfocused on the Bares and the plant operationareas. The view field of the remote cameras can be contmroledfrom the operationscontrol room. 7.3.8 PreventiveMaintenance of Equipment Equipmentin the Bangchak refinexyis subject to preventivemaintenance as describedin Appendix1. 7-7 Appendix3 Emer!encvPlan Fire Prevention and Extinmshine Plan Bangchakrefinery has prepared emergencyplan to preventand extinguishfire whichmight occur in process area tank farm area, tank truck loading area, railway loading and unloadingarea, officebuildings, laboratory, mainteace and warehouse.This plan will be used in case of fire. Fire preventionand extinguishingfacilities in the Bangchakrefinery consist of fire water pumps and pipelines,fire-engine, hydrant system, mobile dry-chemical extinguisher, mobile foam unit, wheeled foam generator, fixed water monitor, sprinker system and other supportingfacilities. Bangchak refineryhas a fSerstaion which is equippedwith equipment,chemical for fire extinguishing,personmel protection equipmentand ambulance.Fire briades are on 24- hour stand-byat the fire station and normallyexercise on weekdybasis.
