The EIR description of the residual coking complex and its impacts indicates that Shell will double gasoline production. The 1993 EIR Clean Fuels Proiect does not specify existing or anticipated production. The project continues the same 1980 BAAQMD permit limiting production of 128,000 barrels/day. The BAAQMD maintains expansion is allowed under 1984 permit modifications that established a refinery emission banking system called either a "bubble" or a "cap". No language in the 1984 permit modification facilitates expansion. Shell's existing refinery includes a residual coker. The 1993 Clean Fuels Project includes a second residual coking complex composed of • a Delayed Coker Unit' including six vertical drums 120 feet tall with a combined length of 180' and width of 30'. The drilling equipment would be approximately 130' tall, making the combined structure 250' tall. In addition there are three heaters 100' tall by 60' square with a 250' tall stack 11' in diameter, and three columns: 175' x 8', 170' x 19' and 145' x 10. • a Coke Barn2 400' x 200' and 100 feet tall. • a Coker Gasoline Splitter Columna, 110' tall x 7' in diameter. • and a Lube Hydrotreatee, to be located near the existing lubricants facility, with a 150' x 2' stack. The second residual coking complex is now under construction 600' from the 1-680 near the Benicia bridge. The EIR does not describe-the capacity of any equipment.

Observation indicates rail traffic has expanded by more than.ten cars/day. • The 1993 EIR suggested (and the County approved) allowing two existing MTBE tanks, with undisclosed storage capacity, be permitted to store either a variety of oxidizing agents or gasoline without consideration of the potential for increased gasoline manufacturing10. No new gasoline storage tanks were proposed in the '93 rp olect • A diagram of the Delayed Coker Unit , Figure 3-1911, lists three sources of feed stock, the last listed references importing residuals from other refineries: 1. Pitch (crude bottoms) from existing crude unit 2. Bottoms from existing catalytic cracking unit 3. Residual from existing lube and imported Indications not included in the 1993 EIR that indicate Shell is significantly expanding gasoline production: 1. Shell closed their other California refinery at Wilmington about four years ago, creating the need to expand production elsewhere. Gasoline manufactured in Martinez is now loaded into multiple marine tankers weekly for delivery to the Wilmington wharf. Shell has only one other West Coast refinery, a smaller. refinery at Anacortes Washington. 2. Tank#12467, a 140,000 barrel exterior floating roof gasoline tank with 100 x annual throughput, (not described as existing or planned in the 1993 EIR), is now under construction 85' from the Marina Vista Ave. roadway and below hillside homes. The tank was originally permitted by the BAAQMD December 27, 1991. Permitting irregularities for this tank include: 8 Response to questioning at Board of Supervisors hearing on Clean Fuels Project, October, 1993 9 Page 11-47, Draft EIR, Chapter 11. Risk of Upset 10 "The proposed project also includes use of the two existing methyl tertiarybutyl ether(MTBE) tanks (Tank 12445 and Tank 12446)to store other oxygenates and gasoline and gasoline blending compounds." Page 3-2, and also page 3-53 which lists four other oxygenates besides MTBE and gasoline, and says "Shell's current Air District Permit to Operate allows them to store these other materials in these tanks, but they also need a land use permit for this action." 11 Page 3-49, 1993 Draft EIR, Chapter 3. Project Description attachment#5 3 • issuing a ministerial permit, exempting tank#12467 from risk analysis because it didn't have a stack nor was it located in a building --without consideration to it's location within a group of six antiquated, exterior floating roof gasoline tanks, five of which are in close proximity to the road below peoples homes. A copy of BAAQMD engineer, Hon Ting's memo to Shell exempting this tank from risk analysis is attached. Also a copy of the current BAAQMD risk screen that exempted the tank from risk review and the 1991 BAAQMD risk screen that it replaced -- which would have required risk screening. Why did the BAAQMD structure risk screening to exempt gasoline tanks? • Tank#12467 was originally ministerially permitted in 1991 when the 1985 AP-42 (which undervalues emissions by seven times) was still in effect. Had it been permitted today the 1985 AP-42 would still have been used as LARGE TANKS (20,000 gallons or greater)12 require application of the out-of-date AP-42. • Shell reported that tank#12467 would not lead to an expansion in production nor present risk on their City of Martinez land use permit application. The BAAQMD permit allows 100x annual throughput and does not require a flow meter. • Bechtel Environmental, Inc. July 1993 submission to the City of Martinez for Tank#12467 land use permit, claimed the tank "will not cause an increase in the present MMC production capacity.13i -- Bechtel is building Shell's Clean Fuels Project. . • Bechtel's report called this a "replacement of four existing fuel storage tanks j with a new unleaded gasoline tank14," the four tanks equaled half the capacity and the second largest tank, #128 was taken out of service in 1981. • Bechtel avoids disclosing that no risk assessment was accomplished and states "Placement of the tank in this location provides a greater margin of safety (with respect to distance from a public thoroughfare) than the current location of Tank 994 which is approximately 45 feet from Marina Vista Blvd.15" Tank 12467 is said to be 85' from the street. � The 1979 E/R reported that "The closest exposure (approximately 100 feet) the public has to oil storage facilities is the "Crude Hill"area...Because of the close proximity of these storage tanks to the public, Shell long ago adopted a policy of storing only low-volatility oils (e.g. 12 BAAQMD tank permitting criteria, page 21-4 (adopted 7/15/91) attachment#11 13 Page 2-1, Shell Oil Company Martinez Manufacturing Complex, Conditional Use Permit Application for Tank 12467, Submitted to City of Martinez, Bechtel Environmental, Inc., July 1993 14 Page 2-2 15 page 4-4 4 heavy gasoils, lube oils, residual fuels and diesel) in these tanks 16" The hillside community is now sandwiched between Crude Hill-- which now contains jet fuel tanks and the six exterior floating roof gasoline tanks below. • Leonard Clayton, a retired air district engineer applying current AP-42 risk analysis, determined that should this tank catch fire and explode, a fireball over one mile in diameter could cause death within a four mile radius. His report" advises requiring an EIR. • John Swanson, permitting chief for the BAAQMD, spoke on behalf of She at a City of Martinez public hearing on this tank and encouraged issuance of a negative declaration rather than examining risk through the CEQA process as requested by most speakers during the three hour hearing. He stated that the BAAQMD issued ministerial permits for all tanks. • The tank location noted on the BAAQMD application, permit and correspondence is inaccurately listed as 3485 Pacheco Blvd., on the other side of the refinery in unincorporated Martinez78. Marina Vista neighbors who saw the BAAQMD storage tank notice with a Pacheco Blvd. address had no way of knowing that this gasoline tank would be located near their homes. 3. Shell converted some of the tanks located less than 100' from Marina Vista to gasoline storage after 1980. This conversion was not anticipated in the 1979 EIR, nor were neighbors notified.. A copy of Shell's application to convert tank 1046 to from jet fuel to gasoline storage to gasoline is attached. 4. In January 1994 the ARB approved a 20% increase (33,103 additional barrels/day) in gasoline loading at six Shell bulk loading terminals in California. The 7,806 additional barrels increased loading at the Martinez bulk terminal equates to 30 more tanker truck trips on Marina Vista. The Marina Vista bulk loading terminal's expansion was not considered in the 1993 Clean Fuels Project EIR. note: the 1979 EIR claimed 54 existing truck trips that would expand by seven to a total of 61 truck trips/day post modemization19 Observation indicates that the current number of truck trips/day is significantly higher. Shell's.bulk gasoline loading terminal is accessed without dedicated tum lanes or other traffic control measures on Marina Vista, an undersized arterial with 10'wide 16 page D-2, Health and Safety, Appendicies Volume DER SHELL OIL COMPANY MARTINEZ MANUFACTURING COMPLEX MODERNIZATION, Prepared by Contra Costa County, October 1979 17 Leonard R. Clayton, Environmental Engineer, May 10, 1994 review of gasoline storage tank #12467 attachment#8 1e In 1991 the CCC planning director requested that the BAAQMD start notifying the County of pending permits. This tank was listed on a 1991 report as a storage tank with the Pacheco Blvd. address. I thought at the time that it would trigger County Ordinance 86-100 requiring permit review for expansions. Instead the tank was constructed in the City and Shell claimed that it wouldn't contribute to an expansion. 19 Page G-1-1, 1979 DER Appendicies Volume 5 lanes and no siding. The entry space before the bulk terminal gate is insufficiently sized, requiring that when more than one double tanker is in line, the back end of the second is on the street and if other tankers arrive, they wait in a traffic lane on the street. 5. Shell ceased internal rail switching about three years ago, and now switches hazardous material on the SP rails through town at night. Was this change accomplished in anticipation of the need to switch more than 100 cars/day, or was Shell freeing up the location of the internal switching yard for a different use? Shell now claims that they have always switched cars through town. The 1979 E/R described the on site rail car switching track that would continue to be used after project completion. 6. During the past three years the number of hazardous material filled tank cars stored on the unprotected rails west of town has increased dramatically. Could Shell be storing cars here in order to establish this expanded use as an ongoing practice -- or has production increased again? 7. Shell began operating a 260,000,000 BTU/hour thermal oxidizer in November 1992 to incinerate marine loading vapors as required by BAAQMD Regulation 8, Rule 44, The Marine Vessel Loading Terminals rule. This rule requires that marine loading emissions of over 2 lbs/1000 barrels of liquid loaded be reduced by 95% by weight from uncontrolled conditions. Shell should have been exempt from this rule based on calculated loading emissions established in the 1984 permit condition modifications which claims that none of Shell's marine loading emissions are higher than 1.7'Ib/1000 gallons loaded. The highest emissions in this permit are for various types of crude oil rated at 1.7 Ib./1000 gallons, even though the only crude Shell loads (for transport to the Anacortes refinery) is San Joaquin Valley crude rated at .06 Ib/1000 gallons. Shell's loading emission factor for finished gasoline is only 1.4 Ib/1000 gallons loaded. How Shell can double gasoline production without public scrutiny: Equipped with a modification EIR that doesn't address expanded gasoline production, but documents impacts from expanded gasoline production, a County land use permit that doesn't limit production, at least three new gasoline tanks20, a thermal oxidizer scaled to accommodate higher volumes of marine gasoline loading vapors, and a new wastewater system of unknown size under construction, Shell will rely on the BAAQMD Rules and Regulations to facilitate this expansion by employing BAAQMD Regulation 2-1-404 (attached) which allows equipment to increase production: "if emissions resulting from such changes are not of such quantity as would cause denial of an authority to construct..." or Regulation 2-2-223 20 Two MTBE tank conversions of unknown size and the 140,000 barrel tank currently under construction 6 i • 1, yo "...Unless previously limited by a permit condition the following shall not be considered changes in method of operation:" 223.1 An increase in the production rate if such increase does not exceed the operating design capacity or the actual demonstrated capacity of the facility as approved by the APCO." Since emissions and impacts are listed in the EIR without a description of existing or future gasoline manufacture or crude oil throughput, Shell can develop up to the emissions described and if the coking emissions increase, Shell will rely on their 1984 "Bubble Permit" that established the emission cap/bank system that allows emissions reduced elsewhere to be transferred, in this case to the residual coking facility. (A description of how Shell's emission banking account was inflated when established and operated in favor of Shell starts on page 13. The BAAQMD has historically accepted misinformation that facilitated unregulated growth. This practice is now required by Regulation 2-1-428 Procedure for Ministerial Evaluations: "...For such projects, the District will merely apply the law to the facts as presented in the permit application, and the District's decision regarding whether to issue the permit will be based only on the criteria set forth in Section 2-1-428 and in Volume 11 of the District's Manual of Procedures." (Adopted July 17, 1991) Will Shell scrap the 1977 emission baseline in favor of the current emissions Banking Credit Period Rule 2-4-202 as follows? "...The last twelve consecutive month period of actual emissions or a more representative twelve consecutive month period, approved by the APCO, occurring during the last five years immediately preceding the banking application date." (Adopted July 17, 1991) THE 1979/8 PROJECT The 1979 Shell Oil Company Martinez Manufacturing Modernization Project EIR proposed a modification project to process high sulfur crude and increase gasoline production by 11,000 barrels/day and jet fuel by 4,000 barrels/day without increasing throughput. The wharf was to be strengthened and modernized to import Alaskan crude oil. Contra Costa County was lead agency. 7 � zyo 1979/80 MODIFICATION PROJECT EIR CLAIMED TO MAINTAIN PRODUCTION -- INSTEAD, PRODUCTION IS EXPANDED BY 42,000 BARRELS/DAY 1. Shell's recorded refining capacity was 108,000 barrels21 when the 1979 Martinez Manufacturing Complex Modernization EIR, (based on Shell's 1979 BAAQMD application,) claimed refining capacity as 128,000 barrels/day. Manufacturing was to be modernized to increase gasoline manufacturing by 11,000 additional barrels/day and aviation turbine fuel production by 4000 more barrels/day22 without increasing crude oil throughput23,. In 1992 production had expanded to around 150,000 barrels/day24 even though Shell's BAAQMD permits still limit throughput to 128,00 barrels/day. 2. The EIR also claimed that existing gasoline production represented as 51% of a barrel of crude oil would increase to 60% per barre125. Long term Shell employees will tell you that Shell was incapable of producing 51% gasoline prior to installation of modernization equipment. Shell Oil Co., Martinez was known as a lube oil plant then. 1980 BAAQMD PERMITS LISTS BIG INCREASE IN GASOLINE PRODUCTION: "the proposed modifications will not increase the overall capacity of the refinery, which is presently 128,000 ba►rels/calendarday. However, these modifications will significantly increase crude distilling capacity, resulting in increased gasoline and aircraft turbine fuel production and a corresponding decrease in heavy fuel production26 The BAAQMD and numerous consultants hired to scrutinize Shell's 1979 application and prepare the EIR, had access to documentation and professional expertise to determine that the EIR falsely described the project's use, exaggerated existing throughput and gasoline manufacturing capability. Experts would know that ship pumps unload whereas loading is accomplished by on shore pumps. There was no reason to install the proposed equipment to unload Alaskan crude oil. Experts would 21 The Oil and Gas Journal, March 20, 1978, page 116 attachment#23 22 79 EIR, pages 1, 13 23 79 EIR pages 1, 13 24 The Oil and Gas Journal, December 21, 1992, page 85 lists calendar day throughput as 146,500 barrels/day, indicating stream day was 150,000 b/d. 128,000 and 108,000 are listed as stream day. attachment#24 25 page 14 26 page, 1, SHELL OIL COMPANY ENGINEERING EVALUATION APPLICATION#26786, 3/19/80, 1. Project Scope-first paragraph. attachment#27 8 know the capacity of proposed equipment and additional tankage would increase manufacturing by 50%. Documentation is available that reports actual ship visits and quantities loaded 27 THE 1979 EIR CLAIMED WHARF IMPROVEMENTS WERE REQUIRED TO IMPORT ALASKAN CRUDE OIL AND INSTEAD IMPROVEMENTS WERE USED TO EXPORT GASOLINE AND CRUDE OIL -' ACTIVITIES NOT ADDRESSED IN EIR The 1979 EIR reported: "Records of vessel operation indicate that the wharf . accommodated a total of 194 ship (tanker) and 247 barge voyages (round trips) during 1977 SHELL'S 1980 BAAQMD ENGINEERING EVALUATION REVEALS AIR DISTRICT KNEW SHELL PLANNED TO LOAD 10.9 MILLION BARRELIYEAR GASOLINE AT WHARF Shell's BAAQMD engineering evaluation addressed loading 10.9 barrels/yr of gasoline at Shell's wharf. Loading 10.9 million barrels/year of gasoline was not mentioned in the EIR. The BAAQMD received wharf use and refining records regularly to know that Shell did not have capability to load gasoline (except through 5" hoses). Had Shell loaded 5.3 million barrels/year gasoline in the past, as reported in the engineering evaluation, BAAQMD rule required permit review for expanded use. How Shell's 1979 EIR, 1980 BAAQMD permit and 1984 modifications exaggerated ship trips and loading emissions to establish the marine loading terminal. And how independent documentation contradicts Shell/BAAQMD tanker visits and wharf emissions. Shell likely planned to export San Joaquin Valley Crude to their A nacortes refinery and arranged installation of the equipment to do so by claiming to import Alaskan crude. The BAAQMD modified their permit in 1984 to accomodate this change even though Shell started loading SJV crude in 1982. 27 State lands Commission barrel tax records for Aug., Sept. & Oct. 1979 indicate that Shell did not have the capacity to load finished gasoline at their wharf until the end of 1979. No finished gasoline was loaded during this reporting period. attachment# 15 US Army Corps of Engineers,Waterborne Commerce Division records indicate a total of only 140 ship visits(loading/unloading) in 1977, this includes bay transfers of crude oil delivered to Shell's wharf by barge. 1977 Shell/BAAQMD reported more gasoline loading at Shell's wharf than reported by the five refineries with wharves in the Carquinez Strait region. attachment#28 9 Why was the focus of the'79 EIR on Very Large Crude Carrier stack emissions, listed as the number one air quality impact, and ballasting emission 28 when gasoline loading emissions, though grossly undervalued in the BAAQMD application were accepted as 3221 tons/year? Prior to installation of the 16" gasoline line from the refinery to the wharf in late 1979 or early 1980, the EIR identified Shell's only marine gasoline loading capability as stringing 5" hoses from the refinery to the wharf. The existing pipelines to the wharf (prior to the end of 1979 when the gasoline line was installed,) were "black lines" too contaiminated to carry gasoline. The BAAQMD received monthly loading records from Shell's wharf to know that gasoline loading would be a new activity that should have been addressed in the EIR. 1. Shell never received Alaskan crude oil but the following equipment listed in the 1979 EIR was installed to unload it from Very Large Crude Carriers 29 • Four 16" and one 10" articulated loading arms supported by additional piles, • an elevated operators shelter, • an emergency shut-off system with hydraulic valves and hydraulic coupling to ships the ships manifold and unloading equipment: • a 36" crude oil pipeline, • . a 16" gasoline line and 4500 ft. of 16" pipeline from Berth #1 & 2 and over Marina Vista pipebadge30 • a 386,000 barrel crude receiving tank. 2. The '79 EIR did not describe loading gasoline. The only gasoline marine loading reference mentioned that a 16" gasoline line would be installed from the refinery to the wharf,. 3. The equipment was installed but never used to import Alaskan crude. Instead it has been used since 1982 to load San Joaquin Valley Crude piped from Shell's Bakersfield oil field, for delivery to the Anacortes refinery. 4. The 1979 EIR claimed the most significant air quality impact resulted from SO2 emissions from Very Large Crude Carriers stacks37 -- which never arrived. Shell's 1980 BAAQMD engineering evaluation 32 listed gasoline loading that should have been addressed in the 1979 EIR: 28 Page C-2-15 and C-2-16 , 1979 Appendicies Volume 29 Pages 12 & 13, Goal I, 1979 DEIR Attachment# 14 30 Page B-2-2, Description Of Proposed Facilities, 1979 DEIR Appendicies Volume 31 Page 41, Air Quality Impact Summary, 1979 DEIR 32 Page 10, BAAQMD permit titled "SHELL OIL COMPANY ENGINEERING EVALUATION APPLICATION#26786, 3/19/80 Attachment#27 10 "The following marine operations shall be limited to those volumes listed in Tables 3 and 4 - WharfNolume I of the Permit Application, namely: a. Gasoline loading 10,950 M barrels/year b. Turbine fuel loading 1,925 M barrels/year c. Ballast for crude tankers 649 M barrels/year without segregated ballast d. Lightering of crude within S.F. Bay 1,099 M barrels/year The Air District knew that Shell did not have the capability to load gasoline, except.by 5" hoses strung from the refinery, prior to installation of loading equipment. The District had also received wharf shipping records for many years prior to Shell's 1979 application and should have questioned Shell's claim to have loaded 5.3 million barrels of gasoline. Why didn't the Air District require vapor recovery for the (undervalued) 322 annual tons.of hydrocarbon emissions anticipated in Shell's application? Wickland Martinez and Tosco both were required to install vapor recovery systems at their loading docks around that time. EIR AND ENGINEERING EVALUATION FALSIFY SHIPPING STATISTICS: 1. The 1979 EIR reported "Records of vessel operation indicate that the wharf accommodated a total of 194 ship tanker and 247 barge voyages (round trips) during 1977. The maximum cargo capacities of the ships ranged from 30,000 to 70,000 deadweight tons." 2. Shell's 1980 BAAQMD Engineering Evaluation claimed: "the increases are for the most part due to maneuvering, and unloading, of the 120 to 189,000 dead weight ton vessels which will visit Shell's wharf in the future. Use of these larger vessels will however reduce the total number of vessels visiting the wharf from 441 to 370 per year....Only hydrocarbon emissions will increase, due to increased ship loading of gasoline. This increase will be offset by additional control of hydrocarbon emissions from refinery storage tanks." (US Army corps of engineers reported 140 total ship visits. Increased gasoline loading not mentioned in 1979 EIR. The 1984 permit modification also credits Shell's baseline for storage tank controls) 3. The 1979 EIR based on Shell's 1979 BAAQMD application, exaggerated existing wharf emissions by claiming 245 tons of hydrocarbon were released from the wharf in 1977 33 The BAAQMD accepted Shell's undervalued gasoline loading formula of 1.4 lbs per 1000 gallons loaded. 4 Wickland is current owner, previous was something like Urich or UCO 35 Page 57, 1979 DEIR, attributed to M.S. Waller, Staff Engineer, Shell Oil Company 36 Unnumbered page 4, SHELL OIL COMPANY ENGINEERING EVALUATION APPLICATION #26786 dated 3/19/80 attachment#27 11 4. The State Lands Commissions started collecting a barrel tax from refineries whose wharves were on State lands in August, 1979. Shell provided explicit documentation as to materials loaded/unloaded. Since most of the same ships visited Shell's wharf in 1979 as in 1977, it is likely that the barrel tax shipping records for a three month period in 1979, reporting that no finished gasoline was loaded or unloaded at Shell's wharf in August, September or October 1979, supports the premise that Shell did not regularly load gasoline. Application of the Shell loading factors suggest that annual wharf emissions averaged about 80 tons/year maximum. A list of the materials and quantities loaded for this period is attached. 5. The US Army Corps of Engineers, Waterborne Commerce records report only a total of 140 ships either visited or were unloaded into barges in the Bay for transfer to Shell's wharf in 1977. Shell claims to have loaded more gasoline and crude oil that was recorded in total for the five refinery wharves located in the Carquinez Straits Region for 197737. [note: the EPA obtained these records which are supposed to list materials comparable to those included in Steve Hill's memo. These records must be reviewed to determine how 15,698,666 barrels of materials (including 5,321,690 barrels of gasoline) could be loaded into approximately 70 small ships.] Gasoline can only be loaded into clean, dedicated ships or barges. SF Marine Exchange record that the same ships visited Shell's wharf in 1977 as the 1979 period in which the State Lands Commission records indicate_no finished gasoline was loaded at the wharf. Finished gasoline marine loading in 1977 is extremely unlikely. 6. The San Francisco Marine Exchange recorded that 108 tankers arrived at Shell's wharf in 1977. These records include the name and size of the ships. Most of the ships that visited Shell's wharf were small T-2 parcel tankers with 15 to 20 compartments, leased to Shell and owned by Werner. The following Werner ships were used extensively by Shell in 1977. The compartments could be loaded with different materials during the same trip. The total capacity of each ship: the Austin -with a net capacity of 11,524 tons the Houston - 11,178 tons the Pasadena 11,340 tons In 1977 only one ship the Judith Prosperity, arriving from Singapore, docked at Shell's wharf October 30, 1977 with net capacity of 35976 tons, was large enough to accommodated 192,566 barrels of gasoline.

The actual emissions due to shipping in the base year 1977 were added to the adjusted refinery baseline." • The inflated emissions included in the application and altered in the EIR to avoid referencing gasoline loading, were included as the 'Actual' and anticipated wharf emissions as reported in the BAAQMD Engineering Evaluation42 as follows: Pollutant Existing Wharf .

The 1.4 gasoline loading factor was politically set and the District knew it should have been 2.4 lbs (per 1000 gallons loaded) based on the existing AP-42. Emissions are based on those included in Shell's application and the number of shipping trips appear to have been created to match. • The 1984 BAAQMD permit modification to the 1980 permit includes 16 pages of reconstructed daily baseline emission profiles for NOx emissions, hydrocarbon emissions, SOx emissions and particulate47 (only the hydrocarbon record is attached). 1977 Shipping statistics, recorded by the SF Marine Exchange (attached) report dates and names of ships that visited Shell's wharf. None of the days that ships visited Shell's wharf register a hydrocarbon increase of 7823 pounds, the hydrocarbon release reported in Steve Hill's calculation for each of the forty ships reported to have been loaded with gasoline at Shell's wharf in 1977. THREE SHELUBAAQMD EMISSION REPORTING AVOIDANCE: I. No benzene emissions were reported from Shell's wharf(as required by law), even though the BAAQMD Marine Rule Workbook estimated Shell's wharf benzene releases as 7.84 tons/year48 : 1. The 1989 BAAQMD Marine Rule Report states that Shell's marine loading organic emissions totaled 415.7 tons/year in 1986 and 522.6 tons/year in 198749, and uncontrolled benzene emission from Shell's marine loading averaged 7.84 tons/yearSO attached 2. Shell/BAAQMD did not report wharf benzene emissions to the EPA s required by law. A copy of Shell's 1987-91 EPA benzene record is attached: EPA TOXIC RELEASE INVENTORY SYSTEM, Year-To-Year.

The BAAQMD did not record Shell's benzene emissions in the AIR TOXICS EMISSION INVENTORY FOR THE SAN FRANCISCO BAY AREA, STATUS REPORT, MARCH 1, 1989. The only benzene releases attributed by Shell include 6800 lbs/yr from the refinery and 960 lbs/yr from product distribution. attached 4. A 1992 benzene outfall study by J. Phyllis Fox, Ph.D.'s determined that the wharf loading benzene emissions outfall was directed to an area on the other side of the refinery, by Las Juntas elementary school. Dr. Fox's study only addressed crude loading. (I was, not aware that gasoline loading was significant at that time.) This report dated May 9, 1992 and stamped "DRAFT"is attached. 2. The BAAQMD required all marine loading activity with emissions over two , pounds per 1000/gallons loaded install vapor recovery equipment. Shell's operating permit, the 1984 modification, undervalued all loading emissions as less than 2 lbs per 1000 gallons. Shell installed a 260,000 BTU/HR incinerator likely in anticipation of loading more gasoline for transfer to Los Angeles. 3. Shell hydrocarbon baseline included 244 tons/year of wharf hydrocarbon emissions. The 1980 Engineering Evaluation forecast wharf hydrocarbon emissions would reach 391 tons/year after modification. In 1992 Shell installed a marine vapor incinerator and reduced their hydrocarbon account by only 226 tons. Apparently the 325 tons/year of sulfur oxides, 22 tons/year of particulate and 115 tons/year of nitrogen oxides wharf emission contributions to Shell's baseline were not adjusted. Could these emissions be covering some of the 1000 additional tons/year of Clean Fuels Project emissions? • In 1992, more than ten years after marine loading started, a 260,000,000 BTU/HR marine vapor thermal oxidizer began destroying wharf loading emissions. BAAQMD permit51 conditions dictate that: "5. Shell shall reduce the baseline VOC emissions under the Emission CAP, permit #26786, for wharf activity for gasoline components, crude oil...by 95%, by weight" • The BAAQMD continued the undervalued loading emissions established in the 1984 condition modifications: "6. .:.tracking...wharf emissions..as specified in Permit#26786..." • In 1993 the City of Martinez hired Gary Rubenstein of Sierra Research to determine whether marine loading was properly permitted and to advise them whether the thermal oxidizer would facilitate expanded marine loading. Mr. Rubenstein's report claimed the wharf was properly permitted and that the thermal oxidizer would not facilitate expanded marine loading. He stated that Shell's hydrocarbon emission 51 August 10, 1992 letter to Shell from John Swanson, Permit Services Chief to Mark Kosliki, Shell. stating that the permit to operate is approved and Conditions#4288 are included. 16 O baseline was reduced by 155 tons as of 1991 and that he had found an error and "In a letter dated February 17, 1993, the BAAQMD corrected this initial error, and the Shell baseline has now been reduced by 226 tons/year.i52 . • Mr Rubenstein does not question why the emission baseline was established with 244 tons of hydrocarbons, offsets provided to expand the wharf hydrocarbon account to 391 tons/year and then only reduced by 226 tons/year--even though the BAAQMD Marine Rule staff report estimated Shell's wharf hydrocarbon emissions as 415.7 tons/year in 1986 and 522.6 tons/year in 1987, before extensive gasoline loading started. • Mr. Rubenstein's report makes no mention of whether the other pollutants attributed to the wharf and included in the emission baseline were reduced: 325 tons/year of sulfur oxides, 22 tons/year of particulate or 115 tons/year of nitrogen oxides. If these emissions continued in Shell's emission bank, are they being used to offset the Clean Fuels Project? 52 Page 23, Review of Air Quality Issues Related to the Shell Oil Company Marine Vapor Recovery Unit, prepared for: City of Martinez Community Development Department, 2/19/93, Sierra Research, Inc. 1521 1 Street, Sacramento Attachment#26 17 A PVUVU'0&0 yNUOUO TRPS 11 '95 �t5 44PM U EPR F"'E t7 G 1 44-1073 Develop JuneP�*,, Agency Washington DG 20460 Externa!Review Draft EPA Esfimating Review Exposure to graft Dioxine-Like (Do No.t CompoundsCite or Quote) Volume ll : Properties, Sources , Occurrence and _.. .. .. .Background Exposures /FORM 88(7.80)' /,/yTRANSMITTAL #of pages A.

The concentration of CDD/CDFs in the final combined refinery plant effluent was below the detection limits. !1" insufficient data are available to evaluate CDD/CDF releases from these sources in the United States, However, Beard et al. (1993) conducted a series of benchtop experiments to investigate the mechanisms) of CDD/CDF formation in the catalytic reforming process. A possible pathway for the formation of CDFs was found, but the results could not explain the formation of CDDs. Analyses of the flue gas from burning coked catalysts revealed the presence of unchlorinated dibenzofuran (DBF) produced in quantities of up to 22.0 ng/g of catalyst. Chlorination. experiments indicated that i dibenzofuran and possibly biphenyl and similar hydrocarbons act as CDF precursors and can become chlorinated in the catalyst regeneration process. Corrosion products on the steel piping of the process plant seem to be the most likely chlorinating agent. Furthermore, CDFs can form by de novo synthesis from chlorinated hydrocarbons like trichloroethylene, methylene chloride, and carbon tetrachloride in the presence of FeCl3 d! and HC! or C12. �r p 3.4.6. Additional Chemical Manufacturing and Processing Sources Rappe et al. (1989) reported the formation of CDFs (tetra- through octa-chlorinated Y ' CDFs) when tap water and double-distilled water were chlorinated using chlorine gas. The �} GDF levels found in the single samples of tap water and double-distilled water were 35 and f'. 7 pg TEO/L, respectively. The water samples were chlorinated at a dosage rate of.340 mg of chlorine per liter of water which is considerably higher (by a factor of one to two orders of magnitude) than the range of dosage rates typically used to disinfect drinking water. Rappe et al. (1989) hypothesized that the CDFs or their precursors are present in chlorine gas. it should be noted, however, that although few surveys of finished drinking water for CDD/CDF levels have been conducted, the few that have been published only rarely report the presence of any CDD/CDF even at low pg/L detection limits and in those cases the CDD/CDFs were also present in the untreated water.

Although the use of graphite electrodes has been eliminated, the potential for CDD/CDF releases from dump sites containing contaminated sludges may still exist (Svensson et al., 1992; Rappe, 1992a). 3.4.6. Petroleum Refining Catalyst Regeneration Catalyst regeneration in the petroleum refinery reforming process has been identified as a source of CE)Ds and CDFs based on testing conducted in Canada (Thompson et al.,. 1990), According to Thompson et al. (1990), "catalytic reforming is a refinery process which is used to produce high octane gasoline. The reforming pr-ocess occurs at high temperature and pressure and requires the use of a catalyst. During the catalytic process, a complex mixture of aromatic compounds known as coke is formed and deposited onto the catalyst. As coke deposits onto the catalyst, its activity is decreased. The high cost of the catalyst necessitates its regeneration. Catalyst regeneration is achieved by removing the coke deposits via burning and activating the catalyst using chlorinated compounds. Burning of the coke produce:9 flue gases which contain CODs and CDFs along with other combustion products.' Thompson et al. (1990) reported total CDD and CDF concentrations of 8.9 ng/m3 and 210 ng/m3, respectively, in stack gas samples from petroleum refinery reforming operations (Table 3-19), It was also found that the CDD and CDF congener distribution patterns observed were similar to those found in municipal, waste incinerator ash and stack samples. Because flue gases may be scrubbed with water, internal effluents may also be contaminated with CDD/CDFs. Thompson et al. (1990) observed CDDs and CDFs in the internal wash water from a scrubber of a periodic/cyclic regenerator (Table 3-20). The Canadian Ministry of the Environment detected concentrations of CODs in an internal wastestream of spent caustic in a petroleum refinery that ranged from 1.8 to 22.2 ppb, and CDFs ranging from 4.4 to 27.6 ppb. The highest concentration of 2,3,7,8-TCDD was 0.0054 ppb (Maniff and Lewis, 1988). CODs were also observed in the refinery's biological sludge at a maximum concentration of 74.5 ppb, and CDFs were observed at a 3-59 6194 �. yo TAN 11 195 05:45PM US EPA REG 'D CERA 41t , UT DRAFT-130 NOT aUOTE OR CITE Table 3-19.

Strock, Secretary, California Environmental Protection Agency James,D. Boyd, Executive Officer, Air Resources Board Since 1982 1 have several times informed your offices of Shell's illegal marine loading operation in Martinez. This terminal operated as the single worst toxic emission source in the Bay Area between 1982 and 1992. It emitted more than seven tons of benzene annually, with outfall centered around the Las Juntas Elementary School in Martinez. Thus far you have chosen to believe the Air District, who failed to disclose to the public that it was Shell's intent to load 10.9 million barrels of gasoline per year at its Martinez wharf facility. This activity was not mentioned in the 1979 EIR, but was included in Shell's BAAQMD application upon which the 1979 EIR was based. That EIR addressed major wharf modifications that would be used to facilitate the import of Alaskan crude oil. Although the equipment was installed, Alaskan crude was never imported. Instead the facilities were used to export gasoline and crude oil, hazardous activities not addressed in the EIR. I'm now informing you that Shell, aided by the BAAQMD, has proposed and received permits for a modification project that includes a residual coking complex, ostensibly to replace gasoline volume lost to their 1993 Clean Fuels Proiect. Based on clues peppered within the 1993 EIR, Shell anticipates using this project to double gasoline production. Attached documentation references expansion indicators. Shell's 1979 Martinez Manufacturing Complex Modernization was also presented as a modification project. It proposed to increase gasoline production by 11,000 barrels/day and aviation fuel by 4,000 barrels/day without increasing the overall level of production. Although Shell's recorded production capacity was only 108,000 barrels/day, the 1979 EIR claimed existing production as 128,000 barrels/day. Even though the Air District permit limits production to 128,000 barrels, production increased to 150,000 barrel/day by 1992. The risk and environmental consequences of this 42,000 barrel expansion were never addressed. Contra Costa County residents have well documented lung cancer, breast cancer and respiratory problems. it's time to stop refineries from using our air to dispose of their carcinogenic wastes. kv \h 1• L4 C) - January 3, 1994 In my opinion, Shell's failure to disclose its true intent amounts to fraud and the Air District officials who abuse the authority of their office are similarly guilty. I encourage your investigation to confirm the above allegations. Subsequent firm action will require Shell to operate lawfully, reemphasize the public's right to be informed and return confidence that its regulators represent the public and not the business they are assigned to oversee.

RA Diana Patrick 1310 Marina Vista Martinez, CA 94553 RE: BENZENE EMISSIONS FROM THE SHELL WHARF Dear Ms. Patrick: As you requested, I have evaluated the etr.issions of benzene from the loading of San Joaquin Valley crude at the Shell Wharf. This crude can contain from 23 to 400 parts per million ("ppm") of benzene in the liquid',2 and 156 ppm in the vapor at 71 F. For a typical tanker load of 200, 000 barrels, about 39 pounds of benzene would be released to the atmosphere.3 Thi - it quite low compared to measured benzene emissions from the of Alaskan crude, which range from 112 to 416 pounds per P00, 000 barrels.4 The low benzene emission value is due in part to the - - low temperature (71 F) that was used in the headspace analysis. � Crude temperatures during loading are typically closer to 100 F. A loading temperature of 100 F could increase the benzene emissions from San Joaquin Valley crude by about a factor of tjo to 78 pounds per 200, 000 barrel loads and would double the health risk. A.

Benzene Emissions Shell Wharf May 9, 1992 Page 2 The maximum annual average benzene concentration resulting from the loading of 200, 000 barrels per day of crude at the Shell Wharf was estimated using the health risk assessment prepared under the Air Toxic Hot Spots Act (AS 2588)6 and is 0. 14 micrograms of benzene per cubic meter of air ("ug/m") .T The location where this maximum annual average concentration would be experienced is shown in Figure' l. The cancer risk associated this benzene concentration is 4 in one million or an individual cancer risk of 4 x 10'6.9 The actual cancer risk could be up to two times larger if the benzene emissions are underestimated due to the low temperature used in the headspace analysis used to calculate the benzene emission rate. This cancer risk assumes an annual average crude loading rate of 200, 000 barrels per day. The cancer risk can be adjusted for another loading rate by multiplying the cancer risk by the ratio of the new loading rate to the old loading rate (i.e. , new/of or new/200, 000 barrels) ,. Sincerely, D A F T J. Phyllis Fox, Ph.D. 6 Radian Corp. , Air Toxic -"Hot Spots" - AS 2588 Health Risk Assessment, March 28, 1991. t Marine loading emissions are split between sources 20025 and 20028 [Radian 1991, Volume II, Table B-I] . The maximum normalized annual average concentration for the sum of these two sources is 0. 694 ug/m3 per g/sec and occurs at location 66 (x-579700, y-4207500) (id. , Volume II, Appendix C-21 . Assuming 200,000 barrels/day of crude are loaded, the benzene emission rate is (39 lb/day) (454 g/ib)/(24hr/day) (60 min/hr) (60 sec/min)-0. 20 g/sec. The' ambient benzene concentration is (0. 694 ug/mj per g/sec) (0. 20 g/sec) - 0. 14 ug m3 . e The cancer risk is (0. 14 ug/m3) (2.9 x 10'5)-4 . 1 x 10'6.

Delayed Coker Unit The u of the new Dela Coker Unit is to upgrade Vacuum Flasher purpose Y� PBT bottoms (pitch or equivalent) and recycled byproduct streams to produce coke and lighter fuels,such as gasoline,jet fuel, and diesel. As can be seen in ��)t ? Figure 3-7, the new Delayed Coker Unit would become a cornerstone in the U v processing of heavy, high-sulfur, petroleum compounds to higher value products. This unit is in keeping with Shell's objective of upgrading heavy fuels and thus maintaining coasting gasoline production levels while producing j►� � � reformulated gasoline. A simplified flow diagram of this unit is given in Figure 3-19. The Delayed Coker Unit would be the most prominent new facility in the proposed project. The Delayed Coker Unit would have two significant features —the coke drums with an associated drilling structure, and the coke barn. The first feature would consist of six vertical drums in a single row surrounded by a support structure approximately 120 feet tall with a combined length o feet and width of 30 feet. Located on to of the drums would i ng f 180 n p be a structure to support hydraulic drilling equipment required for decoking operations. The drilling equipment would be approuimateiy 130 feet tall, making the combined height of the drums and drilling structure approximately 250 feet. To the west of the Delayed Coker Unit would be the coke barn,which would accumulate coke product for shipment. The coke barn_wauldjwthe largest structure associated with the Clean Fuels __Project.

A number of fire and related hazards are posed if a simple leak finds an ignition source . "Liquid pool fire" and fireballs can result from Boiling Liquid Expanding Vapor Explosions ( BLE-EVE-si . 3L---":-s are among the most feared events when sealed tanks are exposed to fire. Although they are called explosions , -.i-ey are not associated with strong blast waves. The;- involve the violent rupture of a container and rapid vaporization of the gasoline. A large rising fireball will form depending on the amount of gasoline present . Although the fireball is generally of short duration, the intense heat generated can cause severe and even 2fatal burns to those exposed over a considerable distance. I used the Automated Resource for Chemical Hazard Incident Evaluation computer program, (better known as "ARCHIE" ) to estimate the potential area that would be affected should this tank BLEVE. This is the most widely used program of its kind. It is routinely used through out the U.S in training, emergency planning, hazard analysis and reference. The output attached, shows that a fire ball of about 40 seconds duration and one mile in diameter could result.

Environmental Protection ADDENDUM TO EVALUATION REPORT SHELL OIL COMPANY APPLICATION NUMBER 7015 Request to Extend A/C for Two Years Introduction: In their letter of August 18, 1993, Shell requested an extension of the Authority to Construct for S-2013, External Floating Roof Tank. The A/C for this tank was issued December 27, 1991. Because this permit application was received on 5/23/91 (prior to the adoption of amended Reg. 2-2), this tank was not subject to the current NSR rule. Per Reg. 2-1-407, an A/C may be extend for an additional two years, subject to meeting the current BACT and offset requirements of Reg. 2-2-301 and 302. The above POC emissions exceed the current trigger levels for BACT and offsets. Therefore, this application must comply with current BACT and offset requirements before an extension can be granted. Offsets were provided for the POC emissions identified below as part of the subsequent permit application number 7562. From the original evaluation report for this application, annual average POC emissions from S-2013 will be: 6.9 lb/day BACT: The District has publicly noticed our Preliminary Decision to issue an A/C for Shell's Clean Fuels Project (app. No. 8407). This project includes several storage tanks. The BACT determination for the Clean Fuels Project (CFP) storage tanks includes vapor recovery for three new tanks, and external floating roofs for the remaining 16 new and modified tanks that will be subject to Reg. 8-5. BACT for the CFP external floating roof tanks includes the following: a. liquid-mounted primary seal; b. zero-gap secondary seal; C. no ungasketed roof penetrations; d. no slotted guide poles; e. every roof fitting shall be of the design which yields the minimum roof fitting losses, per AP-42, Supplement E, Section 12.3.2, Table 12.3-11; and f. adjustable roof legs with vapor seal boots. The above BACT requirements will be included in the permit conditions for S•2013. • � • � 1,yo OFFICE MEMORANDUM August 2, 1991 ' TO: Steve Hill FROM: Hon-Ting Man SUBJECT: Risk Screen Shell Oil Company Permit Application Number 7015 Please provide the risk screen results for the following source: Source External Floating Roof Tank, Unleaded Gasoline, 140 Thousand Barrels Emissions: 0.36 lb/day of benzene (annual average) Risk Assessment Analysis: Request For Information form has not been filled in because the proposed tank does not have a stack nor locate within a building.

I he products of reforming have nearly the same molecular weight as the feed material. This process boosts octane numbers of gasoline components significantly. Platinum catalysts are required. This process produces a gasoline blending component called "Platformate" for gasoline. Alkylation: Most processes in the refinery take long heavy hydrocarbon chains and crack or reform them into lighter products. Alkylation does the opposite. This process takes light gaseous materials (e.g. isobutane and butylene, 4-carbon (C4) molecules) and joins them together to make a longer chain (i.e. iso-octane, a C8 molecule). Certain C8 molecules, such as iso-octane, have very high octane ratings. This process increases the octane number of gasoline,significantly. A simplified flow diagram of the existing and proposed LOP facility is shown in Appendix B-3, for review by the interested technical reader. Shell Oil Company has proposed numerous separate but related activities to make the modernization project fulfill the goals the company has set (Section III, preceding). For ease of understanding, the proposed modifications and construction are described in relation to the goals of the modernization project. The Glossary contains definitions of technical terms. Goal 1: Increase the refinery's capability to process heavier crude oils found predominantly on the West Coast and reduce the refinery's demand for lighter foreign crude oil. To achieve this goal, the company proposei to modify the crude distillation process and vacuum flasher. These modifications would consist of energy conservation measures and hydraulic debottlenecking. Since the crude gravity would be about 220 API gravity, an* additional desalter would be required for the brine/oil separation. The revisions would- expand crude oil distilling capacity by approximately 20,000 B/D. (API gravity: a measure of the specific gravity of oil: the higher the number, the lighter the oil. An API gravity of 400 indicates very light oil, a gravity of 100 very heavy oil. A gravity of 10o is equivalent to the density of water. Almost all oils are lighter than water. This concept is important because it roughly indicates the percentage of desirable light products, gasoline and aviation turbine fuel, in the crude oil. Oil used in Martinez.with a gravity of 150 has about 20% light products while oil with a gravity of 270 has about 40% light products.) The modifications to the crude unit would increase the energy efficiency of the facility by adding heat exchangers and by transferring products at higher temperatures to succeeding processing units. Such transfer would reduce the heat requirements at those following process units. In addition to modifying the crude unit, Shell proposes to increase its hydrotreating and sulfur-removal capacity. The hydrotreating would reduce the quantity of sulfur in the products. Shell proposes to use a Claus plant with a Shell Claus Off-Gas Treating Process (SCOT) tail unit to recover and dispose of additional sulfur from the products. The increased hydrotreating capacity would require the construction of a new hydrogen plant to supply the needed hydrogen. Because the proposed operating mode with heavier crude would produce more residual oil than the current operating mode the company would have an excess supply of residual oils and pitch. Shell proposes to eliminate this excess supply with a new process unit 141 12 called a Flexicoker. The Flexicoker would be sized at 22,000 B/D ("stream day", i.e., at maximum rated capacity) and would process vacuum flasher pitch and clarified oil from the catalytic cracking unit. The Flexicoker would perform a coking function. Coking drives off light volatile hydrocarbons and thermally cracks longer, heavy hydrocarbon chains into lighter products. The Flexicoker would produce a low-BTU gas (a gas with about 100-150 BTU's per standard cubic foot; natural gas has about 1000 BTU's per standard cubic foot) which would be scrubbed to 125 parts per million (ppm) sulfur prior to being burned with refinery gas (primarily methane, ethane and hydrogen from refinery processes) in selected refinery furnaces and boilers. The secondary products of the coking process are called conversion feeds. Coking also has other benefits which are discussed below. The Alaskan oil is shipped in special tankers designed for that purpose. These tankers are 189,000 ton very large crude carriers (VLCC). In order to accommodate the tankers, Shell would have to modify its wharf prior to the start-up of its new process equipment. Goal 2: Reduce inter-refinery movement of unfinished oils (conversion feeds) between Los Angeles and San Francisco areas. The Martinez facility sends its vacuum-flasher pitch to its Los Angeles area facility where it is caked. The resulting conversion feed is then shipped back to Martinez for further processing. Construction of the Flexicoker would reduce the need for these inter-refinery shipments. Goal 3: Improve refinery energy utilization. In addition to saving the energy required to ship materials to Los Angeles and back again, Shell proposes a variety of steps to improve energy utilization. The first would be the installation of numerous heat exchangers to capture heat lost to the atmosphere, thus reducing the amount of heat required from fuel combustion. The second would be to transfer products more efficiently within the refinery. The third involves the installation of a computer for furnace combustion control with oxygen ygen analyzers in all proposed and existing furnaces. In addition Shell plans to improve its distillation processes and to generate process steam in waste heat boilers. Goal 4: Convert high-sulfur residual products into clean fuels for transportation uses and reduce the supply of high-sulfur residual products, which have limited use in the western United States. The supply of high-sulfur residual products exceeds .the demand. This is because environmental restrictions limit the use of high-sulfur oils. The only use for these oils is for bunker fuel; numerous ships call on Los Angeles and San Francisco ports for the purpose of obtaining the high-sulfur oil at prices substantially lower than world market prices. The Flexicoker would reduce the supply of high-sulfur fuel oil by the processes described above. The sulfur would be removed from the Flexicoker low-BTU gas by the Stretford process (a proprietary process used to remove sulfur from gas streams). The sulfur in the hydrocarbon gases produced in the Flexicoker would be removed by a new treatment system. Goal 5: Increase the, supply of aviation turbine fuel and gasoline while maintaining existing octane capability. The facilities required to reduce the manufacture of residual oils at Shell's Martinez refinery (i.e. the Flexicoker and Hydrogen Plant) increase the yields of gasoline and turbine fuel. Gasoline production would increase by 11,000 barrels per day and aviation turbine fuel production would increase by 4,000 barrels per day.

Your Per-tit to Operate, when issued. will contain the following conditions: PERMIT CONDITIONS The following are the proposed conditions for the permit W operate. The purpose of those conditions is to guarantee that: 1. a net air Quality benefit is achieved. 2. all Mission redue-tions required fbr offsets are prov id ed. A. Refinery ,Conditions 1. Total fuel usage shall not exceed 14730 VVE (Net Liquid Fuel Equivalent) Barrels/Calendar Day. (One NLFE Barrel has a heating value of 5.96 V4 BTU. A calendar day basis is an average value determined by dividing the yearly total by 355.) This total shall include all natural Ras, refinery Ras, propane, flexigas, flexicoker coke, cat cracker low4M Ras (CO), cat cracker coke and low-sulfur fuel oil burned In refinery process units, heRters and boilers. Shell will report daily usage of each type of fuel to the District on a monthly basis. 2. Fuel oil usage and allowable sulfur content. a. lbtal low-sulfur liquid fuel used in refinery process heaters and boilers shall not exceed 4000 NVE Barrel s/Cal end or Day or 50M NLFE Barrels/ Stresam Day. A stream day is defined ss the actual daily rate. b. If liquid fuel usage is between 0 and 1,000 NVE Bar- rels/Calen-lar Day the allowable annual average sulfur content of this, fuel is not to exceed 0.491% by 'weight. If liquid fuel usage is between 1,0(X1 and 4,000 NVE Barrels/Calendar Day the allow:ablo annual average sulfur content of this fuel is to be found using the following equation: Weight % Sulfur -_ (434)/(NLF'E 9arrels/C3lendar Day) If t" emissions of sulfur dioxide from the catalytic cracking unit (CCU) are shoran to be less than 4.43 Tons/S*.ream Day, Shell may request the APCO to reeva- lu3te the above equation. 1h13 condition is dependent upon the installation of a District approved CEM monitor for 302 in the No. 3 CO Boiler Stack. c. In the event that the Flex icoker Unit is down, liquid fuel consumption can be increased to a maxtium of 9.000 NVE Barrela/Stream Day. If liquid fuel con- sumption is betty-en 4.000 and 5.0x}0 NLFE Barrels/Stream day during Flexicoker shut dorm, the t3xitmus content of this fuel shall not exceed 4.125 by weiSht. If liquid fuel conwnotion exceeds 5.000 NLFE Barrela/Stream 03y, d u-i ng Fl ex icoker shut down, the m ax i aum sulfur content of this liquid fuel shall not exceed 0. 15 by weight. Shell shall determine the average sulfur content of this liquid fuel on a weekly basis unless commnp►.ion exceeds 4,600 NNE Barrels/Stream Day in which case sulfur content will be determined daily. Shell shall report these data to the District on a monthly basis. 3. 'fie net sulfur content of the coke burners in the regenerator of the Catalytic Cracking Unit (CCU) shall not exceed an annual average of 0.38% by weight. Shell will draw equal size spent and regenerated catalyst samples from the CCU daily and analyze a weekly composite of each for sulfur and coke content. fie net sulfur con- tent of the coke will be determinei from these samples by a method approved by the PAAQMD. Shell shall report weekly net coke yield and weekly net sulfur content of the coke / burned in the regenerator on a monthly basis. 4. Shell will install and maintain continuous monitors to measure H25 concentration in the flexigas system qD and the refinery gas system. The annual average H2S concentration shall not exceed 60 We fbr refinery gas and 17 ppm fbr flexigas.

Dated at San Francisco, the 30th day of November, 1984. Milton Feldstein Air Pollution Control officer Bay Area Air quality Management District i R - Shell WUR Permit Conditions November 5, 1984 A: -.Shell shall operate the units listeu in Table I in such a way tnat any, daily emission increases over the oaselxne protile are offset by • reductions below the profile at a ratio of at least 2.0:1. Compliance shall be demonstrated on a daily basis in the following manner: 1: For each pollutant, actual daily emissions for the previous 364 days plus the day in question shall be ranked in descending order by quantity. The calculation of actual daily emissions shall not be affected by the granting of a variance by the nearing Board of the District unless such variance specifically includes a variance from Paragrapa A (1) of these conditions. In the event of failure or range exceecance of a monitor upon which emissions are based, emissions shall be calculated to be the maximum possible under the prevailing operating conditions in the plant during the event; emission calculations will be based upon theoretical or historical emission factors or other information which demonstrates emission levels to the satisfaction of the APCO 2, The resulting profile will be compared clay by day witn the baseline profile. 3 . The emissions on each day of the current profile will be subtracted from the corresponding day of the baseline prof ile. Positive values are "profile decreases. " The acsolute value of negative values are "profile increases." 4 . Profuse increases will be totalled; profile decreases will be totalled. Profile increases will be doubled, and the decreases will be subtracted from this total. If the result (the profile excess) is positive, Shell is out of compliance. Profile Excess = 2.0 X (Prof-, le increases) - (Prof.ie uecceases) 8 . Emission Profiles and emission factors 1. Tables Ii through VI list the baseline prorises for each pollutant. The baselines reflect actual emissions during the baseline period, less reductions required by regulation of sources under the "cap" , and increased by offsets and increases providea by reductions at operations no; under the "cap' (i.e. , tankage) . The baseline profiles were calculated as follows (this condition contains a summary of the steps used to arrive at the values in Tables II through VI , and should be updated every time the baseline profile is adjusted) : a. Actual refinery emissions for the baseline period 197o- 1978 were calculated using the usage rates contained in 1 Shell' s application 26786 and the emission tactors contained in these conditions. b. Actual refinery baseline emissions were averaged over 365 days. c. Actual refinery baseline emissions were reduces by any amounts required by District regulations. (Reductions so far applied: SO2 emissions from sulfur recovery units; r t particulate emissions from CO boilers) . d. Tne hydrocarcon baseline profile nas been increasea by 2300 lb/day uue to abatement on tankage (tankage is not included under the cap) . e. The hydrocarbon baseline profile has been decreased by 1543 lb/day due to increases -in fugitive emissions from process units. f . The hydrocarbon baseline profile has been increased by 243 .-,�. lb/day due to shutdown of chemical plants not under the cap (application 29376) . g. The actual emissions due to shipping in the -base year 1977 were added to the ad3usted refinery baseline. The baseline daily emissions were ranked in . descending order by quantity. The results ( the baseline profiles) are shown in Tables II through VI. 2. Table VII lists the emission factors to be used for aarine activities. Any changes or additions will be incorporated into these conditions, and must be approved in writing by the APC O. 3. Table VIII lists the emission factors to be used for combustion. Shell may summarize fuel consumption for those furnaces whicn have identical emission factors. These factor are subject to annual review and may be changed to reflect source test results and CEM data. Shell shall determine average sulfur content for each gaseous fuel on- a daily basis, anc for each liquid or solid fuel on a weekly basis, 4 . FCC: unit emission factors will be reviewed annually and wild oe based on source test results and CEM data. 5 . Sulfur plant emissions will be based on the actual measured sulfur emissions. All emissions will ce included in the total. Shell will operate the in-stack monitors in such a way as to provide an accurate measurement uncer all operating + conditions. 6. Baseline profiles for particulates, NO., S02, and CO may be modified in the future in the following ways: i. Shell may increase the baseline profile by provision of additional offsets by abating or shutting down sources not included in the cap. The amount of offset credited snail be the actual emission reduction (as defined in tre uistrict' s NSR rule at the time of offset) resulting froa abatement or shutdown of the offsetting sources, reduced by the offset ratios prevailing at the time of offset. ii. Shell may increase the baseline profile by buying credits from the Emissions Bank or reduce the profile by making deposits in the bank. Offset ratios shall be those prevailing at the time of offset. The baseline profile shall be ad3usted to reflect current RACT emission levels for baseline operations prior to any deposits going into the bank. iii. Tne baseline profile will be permanently lowerea to 7 correspond to reductions required by any future regulations promulgated by the District. iv. The baseline profile will be permanently lowered by the ditf erence oetween baseline emissions ana RAC"r for any source under the cap which is permanently shut down or- ` removea Crow the cap. Tne baseline period uses for determination of emissions shall be the sauce as was usec in the evaluation of Permit 26786 (baseline operations shall be as described in Shell' s Application No. 26786) , unless emissions at the affected source were increased as a result of this or otner permits; in whicn case the baseline period shall be the two year perioc immediately preceding the date of application. V.- If a new source is aodea to those under tae cap, the profile will be permanently lowered by the amount of excess offsets required for onsite offsets under the prevailing NSR rule (I.e. applicable offset ratios and XACT ad]ustmen ts) . vi. If a source already under the cap is modified with a resulting increase in emissions, the baseline profile will be permanen uy lowered by the amount of excess offsets required for onsite offsets under the prevailing NSR rule ( i.e. applicable offset ratios and RACT ad3 ustmen ts) . vii. The baseline profile may be adjusted to reflect more accurate emission factors which may become available, providing: ---, a. Sufficient data are available to apply the revisea emission factor to the baseline period. b. The revised emission factor is approvea by tae APCD, ^---� incorporated into this permit, and is applied to all future emission calculations. viiia Notwithstanding any of the above, the relaxation of any I.;.mu:ts t at increase the potential to emit may require a full PSOINSR review of the source as though construction had not yet commenced on tae source. 7 . The baseline profile for hydrocarbons may be mcdified in the ruture in the following ways: i. The baseline profile will be permanently lowered to. correspona to reductions required by any future regulations promulgated by the District. ii. The baseline profile will be permanently lowerea oy the. difference between baseline emissions and RACT for any source under the cap which is shut down or removed from the cap. The baseline period used for determination of emissions shall be the same as was used in the evaluation of Permit 26786 (baseline operations shall be as I in Shell' s Application 26786) unless emissions _I at the affected source were increased as a result of this or other permits; in which case the baseline period sham be the two year period immediately preceding the slate of application. qD 6 r.e L may r, iz,�. u Q.i I Czi V =.it I z Q L 6 s imp( lowering tne nyurocaroon 1p.

Tne calculation of baseline for the purposes of banking or new source review for any nyorocarcon source under the cap snall be determined pursuant to the provisions of Regulation 2-2-606 . 2 or the equivalent regulation in effect at tne time of application. iv. If a new source is added to nose under the cap, the profile will be permanently lowered by the amount of excess offsets required for onsite ottsets under tne prevailing NSR rule (i.e. applicable offset ratios and RACT adjustments) ; the entire emission increase shall be offset by actual emission reductions from specific identifiable sources subject to enforceable permit conditions. V. If a source already under the cap is modified, the profile will be permanently lowered by the amount of excess o'ffsets required for onsite offsets under the prevailing NSR rule (i. e. applicable offset ratios and AACT adjustments) ; the entire emission increase shall be offset by actual emission reductions from specific sources ources subject to eniorceabie permit conditions. C. ' cion-compliance will result in the following actions: Number of Non-complying days Action for any one pollutant (per 365 day period) More than 0 Shell shall notify the District witnin 15 working days of any non-complying day. One V/N will be issued per day of non- compliance for violation of permit condi- tions. vlore than 5 if the previous 365 days include more than 5 non-complying days, the refinery opera- tions shall be limited in the ways iisted below. Shell may submit alternative ac- tions providing equivalent corrective con- trol for consideration by the APCO. Upon APCU approval, the alternative actions may replace the limitations listed below. These limitations shall remain in effect following any day of non-compliance until Snell has demonstrated compliance for three consecutive days. i. The refinery shall not process more than 124,000 barrels of crude oil per stream day. ii. The refinery shall not process more than 22,000 barrels of Flexicpkec' feed pit stream day. iii.

Hydrocarbon Emissions Associated wiUJA 5th argo Loading Operations q0 Hydrocarbon emissions associated with cargo loading operations will be reduced as a result of the operation of the marine vapor recovery unit. District Regulation 8, Rule 44, requires that the vapor recovery unit reduce cargo loading emissions by at least 95%, or to a level not greater than 2.0 pounds of emissions per 1,000 barrels of product loaded. By comparison, loading emissions without vapor recovery range from <O.l to over 100 lbs/1000 barrels of product loaded. Sierra Research estimates that the installation and operation of the marine vapor recovery unit reduces hydrocarbon emissions from product loading at the Shell wharf by about 200 tons per year. The remaining 5% of hydrocarbon emissions associated with cargo loading operations are those that exit the thermal oxidizer, and are discussed in the earlier paragraph regarding combustion emissions. tIndirect Impacts on Refinery and Wharf Operations Since portions of the Shell Martinez Manufacturing Complex are operating under an emissions profile (or "cap") permit, a reduction in cargo loading emissions could theoretically result in indirect increases in emissions by allowing for increased marine loading activities. However, the BAAQMD has reduced the allowable hydrocarbon emissions under Shell's emissions profiles by an amount calculated based on the amount of loading activity that occurred during the 1977 wharf baseline period. The details of the calculated reduction are included in Shell's September 26 , 1991 letter to the BAAQMD. On an annual basis, Shell's —_� emissions profile was reduced by 155 tons/year under this adjustment: from 563 tons/year to 408 tons/year. A review of the procedures used to make this correction suggested that an error exists. Specifically, there were 18 days during the wharf baseline period when ballast water was taken onto vessels and placed in holds that had previously contained volatile cargos. This operation can generate emissions in much the same way that loading gasoline or crude oil pushes vapors present in the hold (the "arrival component") into the air. However, the emissions profile was not adjusted to reflect the fact that these emissions are subject to control under the BAAQMD's. marine vapor recovery rule. An initial recalculation of the wharf baseline indicates that it should have been reduced by approximately 225 I' tons/year, rather than the 155 tons/year adjustment which was actually made. In a letter dated February 17, 1993, the BAAQMD corrected this initial error, and the Shell baseline has now been reduced by 226 tons/year. The corrected baseline, and a verification that emissions during the period when the error was in effect did not exceed the correct, allowable limits, are shown in Figure 4 above. i Since the emissions profile has been adjusted to reflect the effect of the installation of the marine vapor recovery system, no change in • actual loading volumes is anticipated as a result of operation of the marine vapor recovery unit. While loading operations may increase or decrease in the future, and while the mix of products being loaded may 3/19 /50 SMELL OIL COMPANY ENGINEERING EVALUATION APPLICATION #26786 I. PROJECT SCOPE Shell Oil Company has applied for an authority to construct in order that they can make major changes to their Martinez Refinery. The proposed modifications will not increase the overall capacity of the refinery, which is presently 128,000 barrels/calendar day (BBL/CD) . However, these modifications Will significantly increase crude distilling capacity, resul- ting in increased gasoline and aircraft turbine fuel produc- tion and a corresponding decrease in heavy fuel oil output. Shell states that this modernization project is necessary to enable thew to process heavier, high-sulfur domestic crudes ( primarily Californian and Alaskan) , thus minimizing their dependance on foreign crudes. The proposed new process units and the modifications to exis-_ ting process units are listed below: A. New Process Units (new process heaters in parentheses) 1. Flex icoker ( steam superheater and pitch !water) 2. Dimerization Unit 3. Hydrogen Plant ( steam methane reformer) 4. Sulfur Recovery (Claus/SCOT plant incinerator) S . C3/C4 Splitter 6 . Cooling Tower , 33,000 gal/min. B. Modified Process Units (major modifications) in parentheses) 1. Crude Distillation (new crude furnace and desalter) 2. Catalytic Cracking Gas Plant (modification of main fractionator) 3. Hydrocracking (additional heat exchangers and hydraulic debottleneck) 4 . Catalytic Reforming (new inter-reactor heater) 5. Straight Run Hydrotreaters a. Naphtha Hydrotreater (pump and three heat exchangers) b. Gas Oil Hydrotreater (pump and heat exchanger) 6. Catalytic Cracking Feed Hydrotreater ( furnace modified to burn low-BTU flexicoker gas) 7. Cat Gasoline Hydrotreater (operational changes and increased heat exchange) . e. 0 • 8. Distillates Saturation Unit (additional heat exchanger) 9 . Wharf Revision (new unloading facilities for 189, 000 DWT tankers) For additional details of these new and modified units , including process descriptions and flow diagrams , please refer to Volumes I and II of Shell ' s application. In addition , new tankage will be constructed for the storage of crude oil -(315;000 `BBL), ' gasoline (961 ,000 BBL) and inter- mediate feedstocks (856, 000 BBL) . Shell will also control twelve existing storage tanks with a new vapor recovery system in order to provide hydrocarbon emission reductions. The Bay Area Air Quality Management District has imposed a comprehensive list of conditions to assure compliancy with all District regulations including: 1 . Best Available Control Technology ( BACT) requirements of Regulation 2, Rule 2, Section 301 . 2. 2. New Plant Performance and Emission Requirements of Regulation 10, Rules 8 and 9. 3. New Source Review (HSR) requirements of Section 1309 of Regulation 2 (old codification) . Tradeoffs will be required for non-methane hydrocarbons (HC) , sulfur oxides (SOX) and nitrogen oxides (NOX) , since increases of greater than 250 lb/ day of each pollutant will occur due to worst-day changes in marine operations. }' II. BEST AVAILABLE CONTROL TECHNOLOGY (BACT) Shell will comply with the BACT requirements of Regulation 2, Rule 2, Section 301 . 2 as follows : A. Process Heaters - Shell will construct five new process heaters as part of the refinery modification. 1. The new flexicoker pitch heater will be equipped with a low-NOx burner approved by the APCO as BACT. Shell Will supply the necessary documentation before the permit to operate is granted . d 2. The Steam Methane Reformer (SMR) furnace in the new hydrogen plant will be equipped to burn refinery gas and low-BTU flexicoker gas. These SMR furnaces by design are inherently low NOx emitters. Source tests by the District and Shell indicate an emission factor of 0.06 " lb/MMBTU while burning refinery gas. An even lower factor should be achieved when burning low-BTU flexico- ker gas. This is considered BACT. (note : This unit will not be capable of burning fuel oil) . , a 3. Three new process heaters will be equipped with tri- fuel burners capable of burning fuel oil , refinery gas and low-BTU flexicoker gas. These heaters are listed below: a . Crude Unit Feed Heater b. Catalytic Reformer Inter Heater #1 c. Flexicoker Steam Super Heater . The furnaces will be low NOx emitters when firing on low-BTU flexicoker gas. Shell will document to the APCO that tri-fuel burners are not currently available that are designed for low NOx generation while firing fuel oil and refinery gas. Since. the primary fuel for each of these heaters 070%) will be low-BTU gas , these tri-fuel burners will be accepted as BACT provided a low-NOx design is not available. B. Flexicoker - The flexicoker gasifier will be vented to a Stretford gas treating system capable of reducing the H2S content of the gas by 99•,. The Stretford gas treater is BACT. C. Coke Storage Bins and Purge Silos - These sources will be controlled by baghouses capable of reducing mass emissions of particulate matter by a minimum of 991. D. Claus/SCOT Sulfur Plant - The new sulfur plant will be a three-stage clans plant with a SCOT tail-gas treater . The SCOT Unit will provide overall sulfur removal of >99% and will assure compliance .with the S02 limits of Regulation 9 , Rule 1 , Section 306. 2 (i .e . 250 ppm( v) and 4 lb/ton) . The SCOT unit as proposed by Shell is consi- dered BACT. E. Storage _Tanks -- Shell will equip all new tanks storing ��--- organic liquids with true 'vapor -pressures >1.5 psis' with either-�floating "roofs with approved double seals or with a vapor recovery system demonstrated to provide equivalent or greater control. This is BACT for tankage. F. Pumps and Compressors - Al] npw pumps and compressors will be equipped with mechanical seals or mechanical .packing de- signed to minimize fugitive emissions of organic gases. This is BACT. G. Flares and Marine Vessels - There is no BACT for flares or marine vessels. Z7 III. NEW PLANT PERFORMANCE AND EMISSION REQUIREMENTS Shell will comply with the New Plant Performance and Emission Requirements of Regulation 10, Rules 8 and 9 as follows : A. Rule 8 requires that the H2S content of fuel gas burned in any refinery combustion device not exceed 0. 10 grains/SDCF ( 159 ppm H2S by volume hourly average) . The three year ( 1976-1978) average H2S content of Shell's refinery make gas was approximately 60 ppm (<0.04 grains/SDCF) which -indicates compliance should be attainable with good maintenance of the existing gas treaters. The anticipated H2S content of the low-BTU flexicoker gas ( flexigas) will be. approximately 17 ppm (0. 01 grains/SDCF) or one tenth of the standard . In order to show compliance with this requirement, Shell will install and maintain continuous H2S monitors in both the existing fuel gas system and the new flexigas distribution system. B. Rule 9 requires that petroleum liquid with a true vapor pressure equal toor greater than 1. 5 psia be stored in a vessel equipped with a floating roof, a vapor recovery system , or their equivalents . Shell will comply with this standard by: 1 . equipping their new crude oil storage tank with a floating roof with double seals. 2. controlling the two new naphtha tanks and the three new gasoline tanks with a vapor recovery system. C. Shell ' s catalyst regenerator and CO boilers serving the catalytic cracking unit (CCU) are in compliance with District regulations which are more restrictive than the New Plant Performance and Emission Requirements of Regu- lation 10, Rule R . IV. OFFSETS (NEW SOURCE -REVIEW) "Worst-day" emission increases of particulates , SOx , NOx and hydrocarbons will exceed 250 lb. Therefore, offsets will be required per Section 1309 (c) of Regulation 2 (old codification) . The increases are for the most part due to maneuvering , and unloading , of the 120 to 189,000 dead weight ton vessels which will visit Shell' s wharf in the future. Use of these larger vessels will however , reduce the total number of vessels visiting the wharf from 441 to 170 per year . This will result in annual emission reductions of particulate , SOx and NOx . Only hydrocarbon emissions will increase , due to increased ship loading of gasoline . Th13 .increa3e will be offset by additional control of hydrocarbon emissions from refinery storage tanks . 01 0 Shell elected to calculate baseline refinery emissions on an annual average basis. Therefore, daily emission averages have been calculated for the three year period 1976 through 1978 using fuel usage data , source test results, tank storage infor- mation and approved emission factors. The wharf emission baseline was established using a summary of marine operations for the 1977 calendar year . Shell will offset the worst-day increases with annual average emission reductions on a 2-lb to 1-lb basis. See Tables 1 and 2 for emission and offset summaries. The major emission reductions will be provided by the following measures: A. Sulfur Oxides (SOX) 1 . Improved hydrotreating of catalytic cracker feed is expected to decrease S02 emissions from the cat cracker regenerator by 25%, or approximately 550 ton/yr . 2. Shell will discontinue burning high-sulfur residual fuel oil in the process heaters and boilers. This fuel will be replaced by 0. 12', sulfur fuel oil and by low-BTU flexicoker gas . 3. Permanent shutdown of the lube oil Compounding Unit will reduce fuel requirements equivalent to a 44 _ ton/yr reduction of SC2. 4. Overall SOX emissions from wharf operations will be reduced 127 ton/yr due to decreased vessel traffic and use of 0. 55 Sulfur fuel oil during discharging of large tankers (greater than 170 MDWT) . Note : The District has not given Shell offset credit for anticipated SOX emission reductions from the two existing sulfur plants , since these reductions are mandated by Regulation 9, Rule 1 , Section 306.2. However, control of these sources will reduce total refinery emissions of SOX by approximately 4, 000 Ton/yr . B. Nitrogen Oxides (NOx) 1. Combustion of low-BTU flexicoker gas will provide a very low NOx generating fuel , thus offsetting in part NOx emissions which would result from the combustion of conventional fuels. 2. Computer control of process heaters will assure low excess oxygen , resulting in low NOx eneration . Shell will verity by source testing the anticipated NOx reduction of 66 ton/yr . z.7 3. Permanent shutdown of the lube oil Compounding Unit will reduce fuel requirements equivalent to a 53 ton/yr reduction of NOx . 4. Overall NOx. emissions from wharf operations will be reduced 5 ton/yr due to decreased vessel traffic . C. Hydrocarbons (HC) Shell will offset increased HC emissions from wharf and process units by using vapor recovery or double seals to control new and existing tankage to a greater degree than required by District regulations. This net offset is equivalent to 299 ton/yr . D. Particulate Matter (TSP) 1 . Combustion of low-BTU flexicoker gas will provide low TSP emissions compared to all other fuels . 2. Combustion :of low-sulfur fuel oil in place of heavy residual fuel oil will also result in reduced par- ticulate emissions. The net reduction due to items 1 and 2 will be approximately 12 ton/yr . 3. Decreased vessel traffic will reduce particulate emis- sions from wharf operations by u ton/yr . It is the opinion of the District staff that the emission reductions provided by Shell Oil Company will result _ in a net air quality benefit in the area affected by the emissions from the stationary source. V.
